Pogled v raziskovalne oddelke in laboratorije naravoslovnih, družboslovnih fakultet in inštitutov ter pogovori z raziskovalkami in raziskovalci. Po vsem svetu obstaja potreba po izboljšanju napak merjenja krvnega tlaka (KT) za pravilno diagnosticiranje hipertenzije. Bolezni srca in ožilja vsako leto povzročijo 17,9 milijona smrti in pomenijo znatno finančno obremenitev za zdravstvene sisteme. Trenutno merilno negotovost 3 mmHg bi bilo treba izboljšati. Tokratni gost prihaja s Fakultete za elektrotehniko Univerze v Ljubljani oziroma Laboratorija za metrologijo in kakovost. Asistent dr. Žan Tomazini je s sodelavci razmišljal o sfigmomanometrih in avtomatskih merilnikih srčnega tlaka, ki jih že v osnovi kalibrirajo le s senzorji, ki merijo statični tlak. Manšeta, ki jo ovijemo nad komolcem, pa dejansko meri tlak v njej sami in ne srčnega, ki je seveda dinamična kategorija. Od tod je prišla ideja za uporabo kondenzatorskega mikrofona, ki bi namesto klasičnih senzorjev tlaka v manšeti zaradi njegovih lastnosti pravzaprav merila dejansko dinamiko srčnega tlaka. Med drugim jih je k temu spodbudila odsotnost standarda za dinamično komponento tlaka. To se uporablja v algoritmih, s katerimi merilniki pridejo do vrednosti o sistoličnem/diastoličnem tlaku. V objavljeni študiji so predlagali novo metodo merjenja zračnega tlaka v cevi sfigmomanometra med merjenjem krvnega tlaka z uporabo kondenzatorskega mikrofona. Zasnovali, izdelali in preizkusili so sistem, ki uporablja metodo radiofrekvenčne (RF) modulacije za pretvorbo sprememb kapacitivnosti kondenzatorskega mikrofona v signale tlaka. Radiofrekvenčni mikrofon so preizkusili z nizkofrekvenčnim virom zvoka, simulatorjem krvnega tlaka in s piezoresistivnim senzorjem tlaka kot referenco. Izvedli so potrebne teste za oceno negotovosti sistema. Prototip RF mikrofona ima delovno frekvenčno območje od 0,5 Hz do 280 Hz v območju tlaka od 0 do 300 mmHg. Skupna razširjena negotovost (k = 2, p = 95,5 %) RF mikrofona je bila 4,32 mmHg. Predlagana metoda bi lahko vzpostavila sledljivost naprav za merjenje krvnega tlaka do akustičnih standardov, opisanih v standardu IEC 61094-2, in bi se lahko uporabila tudi pri oblikovanju dinamičnih standardov krvnega tlaka. V pogovoru pa več o tem, zakaj so za preizkušanje hipoteze o točnejšem merjenju srčnega tlaka prišli z uporabo radiofrekvenčne metode pri odzivu tega mikrofona na zvok srčnega utripa.

Parce que… c'est l'épisode 0x301! Shameless plug 3 au 5 juin 2026 - SSTIC 2026 24 et 25 juin 2026 - Troopers 26 et 27 juin 2026 - leHACK 19 septembre 2026 - Bsides Montréal 1 au 3 décembre 2026 - Forum INCYBER - Canada 2026 24 et 25 février 2027 - SéQCure 2027 Description Dans cet épisode, Georges Badro, consultant chez Mandiant à Paris spécialisé dans les infrastructures critiques et les systèmes industriels, explique le fonctionnement et la sécurisation des sous-stations électriques. Architecture du réseau électrique Le réseau électrique se décompose en trois zones : la génération (centrales hydrauliques, nucléaires, thermiques, renouvelables), le transport et la distribution. Le réseau de transmission permet de limiter les pertes d'énergie et surtout d'équilibrer production et consommation afin de maintenir une fréquence stable. Contrairement à un réseau d'eau, un réseau électrique exige un équilibre permanent entre ce qui est produit et ce qui est consommé, sous peine de l'endommager. Les sous-stations sont les nœuds névralgiques de ce réseau de transmission : ces grands parcs clôturés que l'on aperçoit au bord des routes centralisent et redistribuent l'électricité. On y trouve des transformateurs et des disjoncteurs, ces derniers permettant d'ouvrir ou de fermer le courant. Aujourd'hui, ces équipements ne sont plus opérés manuellement mais via du contrôle numérique : interfaces homme-machine (IHM), contrôle à distance, RTU (Remote Terminal Units servant de passerelle vers le centre de contrôle), relais de protection et de contrôle (qui lisent tension, intensité et fréquence pour automatiser des décisions), postes d'ingénierie et équipements réseau. Interconnexion croissante et surface d'attaque Badro insiste sur la disparition de l'« air gap » d'autrefois. Les sous-stations sont désormais interconnectées avec les centres de contrôle, des tiers, des partenaires, parfois directement à internet, voire avec le cloud pour la maintenance prédictive. L'architecture type comprend un réseau IT, une DMZ séparant l'IT des systèmes industriels (OT), un centre de contrôle régional ou national (avec historians, serveurs SCADA, bases de données) relié aux sous-stations via VPN ou MPLS. Chaque sous-station est configurée différemment. Certaines connexions exploitent le Powerline Communication (PLC), qui utilise les câbles électriques existants pour transmettre des paquets TCP/IP. Cette multiplication des accès distants, justifiée par la difficulté d'intervenir physiquement dans des zones rurales, augmente considérablement le risque. Les protocoles courants incluent IEC 104, DNP3 et GOOSE. Scénario d'attaque en Red Team Badro détaille l'approche Red Team de Mandiant, précisant qu'un véritable attaquant ne prendrait pas les mêmes précautions. L'attaque commence généralement par un accès initial à l'IT via phishing ou exploitation de vulnérabilités. Suit une phase de reconnaissance : énumération du domaine, recherche de documentation sur les partages réseau et wikis, fichiers de configuration aux extensions spécifiques, mots de passe en clair (notamment de VPN) et schémas d'architecture. L'accès au réseau OT s'obtient ensuite via un VPN, l'exploitation de flux autorisés au firewall, ou la compromission d'hyperviseurs hébergeant des VM IT et OT. Plutôt qu'un scan NMAP destructeur, l'équipe privilégie une reconnaissance furtive : écoute passive du trafic, analyse des adresses IP et MAC, utilisation de logiciels légitimes d'opérateurs et de scripts spécialisés (Modbus, DNP3). Les vulnérabilités exploitées sont souvent basiques : mots de passe par défaut sur interfaces web, SSH ou Telnet, parfois sur des fonctionnalités cachées utilisées par les fournisseurs et inconnues des équipes. À partir d'une IHM, l'attaquant remonte vers les relais de protection, cibles plus insidieuses permettant des dégâts coûteux. Compromissions réelles Badro compare deux attaques réelles. En Ukraine en 2015, l'attaque a démarré sur l'IT par phishing (malware Black Energy via macro), récupéré des mots de passe VPN, accédé aux IHM, RTU et switchs Moxa, puis ouvert les disjoncteurs et déployé des firmwares corrompus pour empêcher la reprise de contrôle. En Pologne en décembre 2025, l'attaque a ciblé directement l'OT en exploitant une CVE connue mais non corrigée pendant plusieurs semaines sur des firewalls exposés à internet. L'attaquant s'est étendu aux RTU, relais, IHM et convertisseurs série-Ethernet via des comptes par défaut, a lancé des scans locaux, uploadé des firmwares corrompus, supprimé des fichiers système des relais et déployé des wipers sur les IHM. Le constat marquant : malgré dix ans d'écart, les mêmes vulnérabilités basiques persistent. Si l'entrée dans les réseaux IT s'est durcie, le côté OT reste comme l'IT « d'il y a très longtemps » — peu de mots de passe robustes, peu de contrôles — par préjugé d'isolement et par des pratiques de maintenance figées. Attaques avancées et défense Au-delà de la simple ouverture d'un disjoncteur, des attaques plus subtiles ciblent la logique des relais : modifier des valeurs de déclenchement, fausser une LED, ou altérer la fonction de réenclenchement automatique. Ces manipulations restent invisibles jusqu'à une condition rare (un arbre tombant sur une ligne) et sont très difficiles à diagnostiquer sans journalisation. Côté défense, Badro recommande : changer les mots de passe par défaut (et alerter si l'ancien est réutilisé), maintenir à jour les systèmes exposés à internet, restreindre les accès SSH/HTTP à des points spécifiques, contrôler les flux PLC venant des centrales, et surtout établir une visibilité réseau et événementielle à tous les niveaux. La prévisibilité des réseaux OT facilite la définition d'une baseline et la détection d'anomalies. L'approche consiste à décomposer chaque système, comprendre les fonctions et leurs interfaces internes/externes (par exemple le GPS spoofing), puis concevoir protections et détections adaptées — en protégeant avant tout le disjoncteur, élément le plus critique.

When a company moves from lab validation to commercial conversations, the phone does not just ring once. It starts ringing from multiple directions.HPQ Silicon's technology partner Novacium has signed a non-binding, non-exclusive Letter of Intent with GH Technologies, a Hong Kong based B2B distributor, to evaluate potential commercial opportunities for high capacity GEN4 lithium-ion cells in Asia Pacific markets.The LOI covers Novacium's GEN4 18650 and 21700 formats, along with other lithium-ion batteries built on Novacium's GEN4 silicon anode technology. Asia Pacific represents more than 57% of global demand for cylindrical lithium-ion cells, making it one of the most important regions for battery commercialization.GH Technologies entered the LOI following its evaluation of Novacium GEN4 cells, including reported capacity exceeding 6,600 mAh, reported energy density of 319.9 Wh/kg, and international certifications including IEC 62133, UL 1642, and UN 38.3.A related Novacium LinkedIn post added another layer of context, referencing a potential partnership value of more than US$30 million over 36 months. That figure should be understood as potential value, not confirmed revenue or a completed sales contract. Still, when combined with the official LOI, it points to the scale of the commercial opportunity now being evaluated.For HPQ, which holds a 36.8% equity interest in Novacium and exclusive North American rights to commercialize the technology under the ENDURA+ trademark, the story is moving from technical performance toward early commercial execution.WHAT YOU NEED TO KNOWAsia Expansion: Novacium signed a nonbinding, nonexclusive LOI with GH Technologies to evaluate potential commercial opportunities for GEN4 battery technologies across Asia Pacific markets.Potential US$30M Value: A Novacium LinkedIn post referenced a potential partnership value of more than US$30 million over 36 months, which should be viewed as potential value rather than confirmed revenue.High Capacity Results: GH Technologies entered the LOI after evaluating Novacium GEN4 cells, including reported capacity exceeding 6,600 mAh and reported energy density of 319.9 Wh/kg.Major Battery Market: Asia Pacific represents more than 57% of global demand for cylindrical lithium-ion cells, according to the company's release.Phone Ringing: Bernard Tourillon says HPQ is now focused on converting growing market interest into first sales, with about 10 NDAs active.Nimble Strategy: Rather than chasing only large, slow moving contracts, HPQ is targeting flexible buyers in markets such as drones, electric bikes, power tools, defense, embedded systems, and high energy density electronic equipment.CEO Bernard Tourillon:“This LOI provides a framework for Novacium and GH Technologies to evaluate potential business opportunities involving GEN4 battery technologies in Asia-Pacific markets. HPQ's 36.8% equity ownership in Novacium SAS and its exclusive North American license provide the Company with access to these technologies for Canada, the United States, and Mexico under the HPQ ENDURA+ trademark.”INVESTOR TAKEAWAYHPQ Silicon is progressing from lab validation toward early commercial execution. Novacium's GEN4 battery technology has now attracted an Asia Pacific LOI with GH Technologies, following reported high capacity cell performance and international certifications. HPQ's 36.8% equity interest in Novacium and exclusive North American commercialization rights under the ENDURA+ trademark give the company multiple ways to participate if the technology continues to advance.For investors, the key question is no longer only whether the technology can perform in testing. The next stage is whether HPQ and Novacium can convert interest, validation, and commercial discussions into first revenue, customer adoption, and a scalable commercialization model.

Howard Penrose: [00:00:00] Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow. Allen Hall: Howard, welcome back to the program.  Howard Penrose: Hey, thanks for having me.  Allen Hall: It’s about time everybody realizes what motorDoc can do. There’s so much technology, and I’ve been watching- Yeah … your Chaos and Caffeine podcast on Saturday morning, which are full of really, really good information about the motorDoc as a company, all the things you’re doing out in the field, and how you’re solving real-world problems, not imaginary ones- Yeah real-world problems. Oh, yeah. Yeah, and  Howard Penrose: whatever annoys me that week. Exactly. And, and whatever great coffee I’m trying out. Yes. Except for a few. We’ve had the ReliaSquatch down our- Yes … um, a couple of times. Uh, yeah, no, I, I enjoy it, and we gotta get you on there sometime. I don’t do- I, it- … a lot of interviews other than an AI character we put in. Allen Hall: It’s a very interesting show because you’re [00:01:00] getting a little bit of comedy and humor and s- Yeah … and a, and a coffee review, which is very helpful because I’ve tried some of the coffees that you have reviewed, that you’ve given the thumbs up to. But if you’re operating wind turbines and you’re trying to understand what’s happening on the drivetrain side, on the generator, everything out to the blades even, main bearings, gearboxes- Yeah all those rotating heavy, expensive parts, there’s a lot of ways to diagnose them-  Howard Penrose: Yes …  Allen Hall: that are sort of like we can look at a gear, we can look at a joint, we can look at roller bearings, whatever, but motorDoc has a way to quickly diagnose all of that chain in about- Yeah … 15 seconds.  Howard Penrose: Well, a little longer than 15 sec- more like a minute. A minute, okay. It feels like paint drying. But- Uh, in any case, yeah. Uh, uh, and, and what’s kind of funny is, um, back in the ’90s, uh, EPRI actually accidentally steered the technology away from its [00:02:00] core purpose, which was in 1985, um, NAVSEA, the US Navy, had done research on using current signature analysis for looking at pumps, fans, and compressors, the bearings, the belts, the components, all the rotating components using the motor as the sensor. Not too much different than we are now. I mean, mind you, we got better resolution now, we’ve got, uh, more powerful– I mean, I look at my data from the ’90s, and now it’s completely different. Um, and then Oak Ridge National Lab, same thing, bearings and gears in motor-operated valves. So in 2003, we were the first ones to apply electrical and current signature analysis to some wind turbines in the Mojave Desert. Wow. Yeah. So, um, nobody had tried it before. Everybody said it couldn’t be done. And, uh, that was a bad thing to say to me because- … it meant I was gonna get it [00:03:00] done. Right. At that time, um, we were looking at bearing issues and some blatant conditions with the, um, with the, uh, generator using a technology called Altest, ’cause I was with Altest at the time. And, uh, I had taken an EMPath software and blended it with a, a power analyzer, and they still have that tool to this day. I was using that technology all the way through 2015. 2016, I should say. And then- And then switched over to the pure EMPath, which was more of an engineering tool. And then more recently, in 2022, uh, made the decision to ha- to take all the work we’d done on over 6,000 turbines, uh, looking at how we were looking at the data and what we were doing on the industrial side, and took a, uh, created a current signature analyzer that would do one phase of current to analyze the entire powertrain. Allen Hall: So when you tell [00:04:00] operators you can do this magic, I think a lotta times they gotta go, “ Howard Penrose: What?” Oh, yeah, yeah. They don’t understand it because they’re used to vibration- Right … which is a point analysis system. Right.  Allen Hall: Vibration at this- Yeah … particular location. Yeah. One spot- Even if it’s- … or a couple  Howard Penrose: spots triax, they’re reading through material, up through a transducer. Hopefully, they put it above the bearing and not in the middle of the machine like everybody is now, because everybody’s trying to sell a sensor. Right. True. They’re not selling a- they’re not selling accuracy. They’re just selling sensors. Right. So, um- Yeah … you know, uh, I, I’ll, I’ll even talk about one of the companies here. We’ve got Onyx here, and they do it right. I mean, they’ve been doing it right pretty well because we’ve been doing some of the same towers they’re on, and we can match the data they’re getting. Oh, good. Right? Yeah. Uh, so but they get it in multiple spots, and there’s areas they can’t quite reach, so we’ll detect those areas as well. So it’s a good melding of two technologies.  Allen Hall: Oh, sure. Sure,  Howard Penrose: sure. You know what I mean? Yeah, yeah, yeah. So when you have electrical signature and you have vibration, but in [00:05:00] cases if you don’t have vibration, we’re a direct replacement.  Allen Hall: Because the generator- I  Howard Penrose: dare say that.  Allen Hall: Yeah. Whichever–  Howard Penrose: I dare say that, um, with- Well, the  Allen Hall: generator is acting as the sensor. Howard Penrose: The air gap. The air gap in the generator s- specifically, yes. Yeah. Generator, motor, transformer. Right.  Allen Hall: Yeah. So any of those- Mm-hmm … you can clamp onto, look at the current that’s on there. Everything that’s happening on the drivetrain, in the gearbox, out on the rotor- Yep … main bearings, all of that creates vibration. Creates a torque. T- a, a torque. Yeah. Yes, more exactly a torque. Yeah. And that’s seen in the generator, in the current coming out of the generator. Yes. So those signals, although minute, are still there. Yes. So if you clamp onto that current coming out of the generator, you’ll see the typical AC sine wave sitting there. But on top of that- Is all the information about how that drivetrain is doing  Howard Penrose: Absolutely, and everything else. Anything electrical comes through [00:06:00] that. So what you do is just like vibration, you do a spectral analysis. So every component has a frequency associated with it, just like vibration. It’s, as a matter of fact, I, I keep having to try to explain to people electrical and current signature analysis is no different than vibration analysis. It’s the same concept. We use the same tools. The signature looks just a little different. It’s a little noisier, um, but you need that noise in order to see everything. But we have a time waveform, and instead of, um, inches per second or millimeters per second, whatever, you know, uh, velocity, acceleration, and displacement, uh, what we end up with is decibels is the optimal method. You can look at straight voltage signatures at those points or, or current signatures, but the values are so small that you have to look at it from a logarithmic standpoint. Right. There are some benefits to it versus vibration, and there’s some things that aren’t as good as vibration. [00:07:00] So, you know, we, we do… You have to… Any technology is gonna have their strengths and weaknesses. Sure. So we will see everything all at once. Load doesn’t matter. Right. Speed doesn’t matter. It’s… Only reason speed matters is the location of the frequencies. Uh, so the higher the resolution, meaning the longer you take data, the less chance you have on a lightly lo- loaded machine of blending the peaks together. Right. Um, on the flip side, if I have two bearings turning at the exact same speed, I couldn’t tell you which one it is. Because they’re the same. Right.  Allen Hall: And the mechanical features of that bearing is w- what creates the signal that you’re measuring. Exactly. So if a bearing has five rollers versus 10, just imaginary thing. Yeah, yeah. Five rollers versus 10 has a different electrical signature, so you can determine, like, that bearing, that 10 roller bearing- Yes … has the problem, the five is fine. Yes. Yeah. That’s the magic, and I think people don’t translate the mechanical world into the electrical world. That that’s what’s [00:08:00]happening. They,  Howard Penrose: they don’t because, because what’s happening is they named it wrong.  Allen Hall: Yes.  Howard Penrose: A majority of our users are mechanical folks. Sure. Our vibration analysts and stuff like, ’cause they know how to look at the signatures. Right. Everybody tries to force it on their electrical people, and electrical people go, “We don’t know what this is.” Yeah. And it’s, it’s, it’s a matter of that training and, and, you know, in the electrical world, you’re not taught to look at that. Right. Yeah. It doesn’t matter. Mechanical world, you’re taught to look at that. So our intern, we were trying to bring in electrical engineering interns and found out that just wasn’t working. So last year, I brought in my first, uh, intern that’s, you know, he’s been with us now since I brought him in. Okay. Uh, and, uh, Amar, and, uh, you know, he’s helped us develop our vi- uh, vibration software to go along with it. Guess what? It’s the same thing. It’s the exact same sy- system Um, but we just take in a vibration signal instead. But he picked up on it immediately as a [00:09:00] third-year college student. I can take somebody with a decade as an electrical engineer with a PhD and they can’t figure it out.  Allen Hall: Well, because you’re, you’re taking real- Because it’s different. Yeah. It’s r- well, it’s real-world components-  Howard Penrose: Yeah …  Allen Hall: creating electrical signals. That’s hard- Well, you have- … to process for a lot of people. Yeah,  Howard Penrose: yeah. It’s  Allen Hall: just not  Howard Penrose: something that we do every day. But that’s… If they, i- if we sa- i- i- if you’re looking at vibration and you start looking at the sensor, it gets complicated too, ’cause guess what? It’s an electrical signal. Right. It’s, it is technically electrical signature now. It’s converting a  Allen Hall: mechanical signal- Right … into an electrical signal, which is what’s happening in the generator anyway. Yeah.  Howard Penrose: Whether it’s a piezoelectric cell that’s generating a small signal- Yeah … on top of a small waveform that you then take out, you demodulate, uh, or it’s, uh… So you take that carrier frequency out, or it’s a MEMS sensor, which is the same thing. You know, the, it just sees some slower s- It, it does more of a digital output. So you, you, you know, you have those, or you [00:10:00] have this, which just basically uses a component of the machine to, to, as its own sensor. There is one other difference between them, too, and, uh, I find this very useful when I’m going out troubleshooting something that other people can’t figure out, uh, ’cause we use all the technologies. So in this case, it would be, uh, the structural movement. Okay? So, so say I have a generator and there’s something wrong with the structure, and the whole machine is vibrating. So y- well, if I put a transducer on it, they might think that’s vibration or something else. We don’t see it. Right. We only see directly exactly what’s happening with the machine. Sure. So a lot of times when we go in to troubleshoot something that people have done vibration on and everything else, it’s been pro- a, a problem for them for years. We walk in, and all of a sudden we’re identifying whether it’s the machine or it’s something else right off the bat. Then we can take a look at the vibration data and [00:11:00] say, “Okay, it wasn’t the bearing or the bearing, um, structure. It was, you know, the mounting.” Right. It wasn’t  Allen Hall: fastened  Howard Penrose: down properly. Yeah,  Allen Hall: yeah. Right.  Howard Penrose: Go tighten that bolt. Right, exactly.  Allen Hall: Well, I mean, that’s the cheap answer. Yeah. I’d rather tighten a bolt than rip apart a motor or a generator- And, and- … every day …  Howard Penrose: and that’s the whole point. Now, there are other strengths that go with it. So for instance, on the powertrain of a wind turbine, I can tell you if you’ve lubricated the bearings correctly. Wow. Because part of what we do is we do take those electrical signatures, and we convert those over to watts. Watts is an energy conversion. Sure. So you see that as heat or some type of loss. So whatever, whatever’s being lost there is not being sent to the customer. To the outside. Right. Making money. So, um, if I’m taking a look at, say, a main bearing, I might see watts or kilowatts of losses. So you’re gonna have some ’cause you have friction, right? But when we see it increase on, say, a roller, [00:12:00] or the rollers, or, or the cage, that’s usually an indicator that I have a lubrication issue. Or if we only see it on the outer race, that means that they didn’t clear out all the old grease when they were lubricating it, ’cause the rollers then have to ride across it- Right … ’cause it dries up.  Allen Hall: Sure.  Howard Penrose: Uh, and will carry contaminants. So if you see that, you go up, clean it up, you’ll extend the life of the bearing. Absolutely you will. Without having to do a lot of work. So, uh, we, we look at our technology as more so early in the, in the stage of a condition. I don’t wanna call it failure, ’cause it’s not a failure. It’s something that’s mitigable. And I made that word up. You can mitigate it. Meaning you can go up and correct it and extend the life of that component. Sure. Uh, in gearboxes we’ll see problems with, um… Well, the, the one we’re talking about here a fair amount is all the circulating currents going on uptower. We did that research. The current signature analyzer we have is a direct result of doing wind turbine [00:13:00] research just on circulating currents uptower, ’cause we conferred everything over to, to sound at 48 kilohertz. And so that gives me a 24-kilohertz signal. That high-frequency stuff, which we’re researching in CGRE, and IEEE, and IEC, is called supra harmonics, which I– we talked about that before. Yes, we have. Yeah. And, uh, so when you start seeing that in the, in, in the current that’s circulating uptower because the ground that goes from the top of the tower down is for- DC lightning protection. And lightning protection, yeah. It’s not meant for, um- Not for  Allen Hall: high frequency- Yeah …  Howard Penrose: currents. Yeah. Uh, we, when we measured it, when we mapped out dozens of towers of all different manufacturers, we found that the impedance about halfway down the tower is where it ends. Sure. The, the resistance. And then the increased, uh, the high-frequency noise turns any of your shaft brushes into resistors. And at about 15 kilohertz, no current is [00:14:00]passing through them. It’s all passing the bearing, which becomes more conductive the higher the frequency. So with 60% of main bearings failing due to electrical currents, it’s actually currents that are circulating uptower. It’s not static. There is some static up there, but it’s not static. It’s coming from the controls, the, the generator, and everything else. Inverters,  Allen Hall: converters.  Howard Penrose: And we’ve seen up to 150 amps passing through a, through a bearing.  Allen Hall: So I– We run across a lot of operators who have been replacing main bearings, and they don’t know the reason why. Yeah. And I always say, “Well, call Howard at MotorDoc because I would almost bet you you have the f- high frequency running around uptower in the nacelle- And the next main bearing you put in there is gonna go the same way as the- Yeah … first one you put in there. Until you cut off that circulating current and then the cell, you’re just gonna continue with the problem. Then you haven’t eliminated the problem, you’re just fixing the result of that problem. Yes. But it takes- Yeah, you’re, you’re- How, [00:15:00] how, well, how long- You’re replacing  Howard Penrose: a fuse.  Allen Hall: Right, you’re replacing a fuse. Yeah. How long does it take you to s- to determine- An expensive fuse. Yeah. Yeah. Oh, yeah, ’cause you’re taking the rotor down. Yeah. Well, how, how fast can you determine if you have harmonics uptower that are gonna be causing you problems? 120 seconds.  Howard Penrose: Okay.  Allen Hall: So that’s the thing. I think a lot of- I mean,  Howard Penrose: that’s of the actual data collection time. So you clamp on uptower, uh, and then you can… Well, the way we have it set up now, you just tell it you wanna collect data every five s- uh, five minutes, and then you go downtower, let it collect its data, go back up, grab it. Um, it’s like… It’s huge. It’s this size. So, um, and then you connect- It plugs into a laptop. Yeah. Plug it into a laptop or any type of tablet. Um, it, it’s Windows now. I’m trying to get away from Windows. We’re gonna have Linux systems, uh, as well. Uh, and then you use that to, um, just collect that data, and then you press another button. Now it pops up, and it tells you if you’re in danger or not, [00:16:00] the amount of current passing through the bearing, and the frequencies all the way out.  Allen Hall: So the ideal is you’re gonna have this kit with you in the truck. Yeah. And as you see these problems pop up, you’re gonna clamp on uptower. Yep. You’re gonna measure these circulating currents, and you’re gonna know immediately if you have another mechanical issue, a, a lubrication issue- Oh, yeah. It’ll look at- … some kind of alignment issue, or- You’ll get all  Howard Penrose: of this information at once. So you- Right … if you go on the power side. So certain turbines, like anything that has the transformer downtower, you don’t have to climb. Right. GE. I mean, I don’t climb. So, uh, uh, you know, th- and that was part of the, the concept behind when we started down this path because I’ve been in the wind industry since 1997. So one of the things I always saw was, and, and we talked about even, you know, here when it was called AWEA, and we were talking always on the health and safety side about wearing out the technicians. Um, so we discovered that, you know, what was it? Almost 60% of the [00:17:00] turbines you didn’t have to climb. Right. Oh, yeah. And even the ones you do, you go up, you set it up, and it’ll tell you where you need to focus. The other thing in the powertrain, let alone the generator, when we do a sweep of a site– Now, if we do a straight electrical signature analysis, I’d term that one as a technician’s tool. Sure. That’s more of an engineer’s tool. Uh, a lot more data, a lot harder to set up. But even though I’m saying harder to set up, it’s still pretty easy. It’s still minutes. Right. Yeah. Most technicians will collect data with, like, a couple hours worth of training. Yeah. You g- You basically gather that data, and if you’re getting a site, so we’ll go out– I love going out in the field. So we’ll go out in the field, especially if it’s a tower we don’t have to climb I’ll knock out, uh, well, let’s just say I’ll, I’ll, I’ll name one. Say a GE 1.6. I’ll knock out one of those every eight to 11 minutes, depending on how you get to the tower.  Allen Hall: So that’s a full diagnosis of drivetrain- Yeah … plus anything odd happening- Yep with circulating currents and all that [00:18:00] can- Oh, no, no. Circulating- Or just- … current, that’s a- That’s a separate thing at tower … separate study that- Okay … you have to do that uptower. But anything, anything drivetrain-wise, you can be in and out- Yeah … in a couple of minutes. Yep. Okay. So there’s a lot of operators that have end-of-warranties coming up, right? Yes. There’s been a lot of developments, so they’re kind of running into the end-of-warranty, and they don’t know the health status of their drivetrain. Same thing for a lot of operators that are in- Yep … full service agreements, and they’re questioning whether they’re getting their money’s worth or not. Yes. I always say, “Call Howard at Motordoc. You guys can have a whole site survey done maybe in a couple of days, and you will know all the problems that are on site for the lowest price ever”. Yeah. It’s crazy how fast you can do it and how accurate it is. I talk to operators that use your system, so I hear you. Yeah. Your podcast, listen to your podcast, I’m calling your customers to find out what they say, and they love it. Oh, yeah. They can’t believe how accurate it is. Yeah. Well, the thing about that is we as an industry need to make sure that our turbines are operating at [00:19:00] maximum efficiency. Yep. And if a simple tool like the Motordoc EMPath system exists, we need to get customers, operators in line to start doing it worldwide. Australia- Oh … Europe-  Howard Penrose: Yeah. We- … Canada. Australia, we’re trying to get into, but right now we even have OEMs using it through North- That’s good … and South America, Asia. Good. Uh, Middle East, um, and, uh, and some of Europe. Good. So it’s, it’s, it’s really taking off. Uh, I’d say probably our biggest market right now is Brazil. Sure. They’re going crazy. Well, the, the turbines are- They’re having a lot of problems. Yeah.  Allen Hall: Right. And the, well, those turbines have a h- high usage, right? So because- Oh, yeah … the winds are so good, they’re operating at, like, capacity factor is above 50%. Yes. It’s insane. Yeah. So there’s a lot of wear and tear. There’s no downtime for those turbines.  Howard Penrose: Yeah. Well, and, and people think it’s all the starting and stopping. It’s not. No. It’s a grid-related issue. So we have- Sure … we have a low frequency. And you know some of the stuff I volun- I, I’m, I’ve been volunteered for- [00:20:00] Yeah … uh, including the CIGRE thing. Um, so I get to sit in the grid code committees for IEEE and put my, and our input into that, uh, and kind of watch the back of the IBR industry, right? Mm-hmm. ‘Cause there’s a definitely bias against our industry. Um, and I also, uh, get to hear what’s going on in the grid side of things from CIGRE worldwide, and it’s all very similar, and it has to do with low-frequency oscillating currents- Yes … called subsynchronous currents- Yes … which are low enough not to damage large synchronous machines. And they thought, and there’s books written on this, by the way, multiple books written on wind turbine impact- Uh, and they’re seeing now, um… Well, we detected it first, along with Timken. Hank, uh, and, and I went out to a site, and we detected for the first time, because of how they wanna do the testing and where the site was located, we saw the oscillating torque [00:21:00] in the air gap, ’cause that’s one of the things the technology does. It actually measures the torque, air gap torque. Sure. So we were watching the oscillating torque as a tower started up. And so we did, we went through the rest of that site looking at the same stuff in the same way. It increased our time and data collection, and time on site. But then we started looking for it at other sites, and going to pass data because I don’t have to go back and retake data. Right. And we’re like, “Oh my God. It’s everywhere.” 16 hertz, 21 hertz, and 50 hertz. And we found a paper that specifically identified that as the sub synchronous frequencies for 60 hertz. So we know what they are also for 50 hertz. Once we identified that and we saw how much the torsi- torque was oscillating, we worked with Shermco, who got us some information on Y-rings that were failing. Yeah. And they were all failing… When the metallurgy was done, they were all failing from fatigue. And you’re like, fatigue how? What’s fatiguing these connections? [00:22:00] Well, the fatigue is that air gap torque- Exactly … because you’re basically causing the, the, everything to oscillate a little bit, and that causes the windings to move slightly. It’s a living,  Allen Hall: breathing machine-  Howard Penrose: Exactly … this generator  Allen Hall: is.  Howard Penrose: Yeah.  Allen Hall: It’s not  Howard Penrose: static. It’s definitely not sta- no electric machine is static. No. Even a transformer’s not static. Right.  Allen Hall: So- There’s a little  Howard Penrose: bit of wiggle going on there all the time All the time. And it’s minute, so it takes a long time. Right. And what, uh, uh, everybody… Well, first people thought it was a particular manufacturer, which it wasn’t. Turned out every defig’s failing the same way. Sure. You’re fatiguing it. Yeah. Every bearing is failing the same way, even in the gearbox, main bearings, and everything else. Right. All of these conditions are happening across all the OEMs, but they’re not allowed to talk. Well, this is, this is the thing that  Allen Hall: I like watching your podcast.  Howard Penrose: Yeah.  Allen Hall: The Chaos and Caffeine. It comes out Saturday mornings. It’s on YouTube. If you haven’t- Yeah … clicked into it, you should click into it  Howard Penrose: because a lot of these issues are discussed there. It’s definitely, um… [00:23:00] Let’s just say I’ll speak Navy quite a bit. Allen Hall: It’s a great podcast, and I think what you’re doing with the EMPath system- Yes … at motor dock is really a game changer. Yeah. I’m talking to everybody, all the operators I know. I keep telling them to call you and to try the system out because it’s so inexpensive and it does the work quickly and efficiently, and it’s been proven. There’s no messing- Oh, yeah … around when you’re talking to MotorDoc. I…  Howard Penrose: Somebody dared tell me that there’s no standard for it. There’s ISO standards for it. Yes. There’s IEEE 1415- Yes … which I chair. Uh, and there’s other standards coming out- This is- … associated with it. And there’s a document that I also chair for Sea Gray- Called A178, which is the practical application of the technology. So it’s well-documented. There are traceable standards for it. I need more  Allen Hall: operators to call you- Yeah … and to talk to you and get systems in the back of the trucks that they can use to check out the health of their gear boxes and their drive trains and their generators. How [00:24:00] do they do that? Where do they go? Where, where’s, what’s- Well- … the first place they should look for?  Howard Penrose: Uh, info@motordoc.com. Okay. I get all, I get all of those as well, so do my people. Um, or, uh, LinkedIn. LinkedIn’s really good.  Allen Hall: Look up anything. Yeah.  Howard Penrose: Yeah, yeah. So, so either the company at Motordoc, or, uh, I’m, I sh- I’ll show up either searching for my name or, uh, linkedin.com/in/motordoc. Come straight to me ’cause I’ve been in, on LinkedIn forever, so- Right, just- … I got to do that … look up  Allen Hall: Howard Penrose, P-E-N-R-O-S-E. Yep. Or go to motordoc.com is- Yep, motordoc.com … the website address.  Howard Penrose: Yep. There’s a lot of great information there. And we have partners, and we have people. We’re growing the company. You know, talk to me. I, I’ll- Yes … I like answering the phone and talking. It’s, it’s a thing. My people go, “Can we answer the phone one?” No. Um, but, but yeah, we, we, y- when you call us, you’re not just dealing with a single person. Right. The Motordoc is far more expansive. Right now, we [00:25:00] just got our partnership with, uh, Hitachi and, and Juliet- Yeah, that’s great and stuff like that. Uh, we’re helping them with certain things. Uh, we’re partnered with some of the big OEMs, almost all of them, um, you know, helping identify the issues, you know. And, and when users contact us, often they’ll tell us what’s going on, and we’ll, we can, uh, sometimes say, “Yeah, it’s this, and here’s how we prove it.” Allen Hall: Yeah. That’s the, that’s the beauty- Yeah … of calling Motordoc. So I need my operators that, that watch the show- Yeah … worldwide, go online, go on LinkedIn, get ahold of Howard, get ahold of Motordoc, and get started. Yep. Howard, thank you- And- … so much for being on the podcast. Yeah. This is fantastic. I love talking to you because- it’s, it’s like talking to, you know… Uh, no, really, it’s talking like someone who’s a real good industry expert, who’s been there a long time, and understands- Yeah … how this  [00:26:00] works.

I’m your host, Allen Hall, and I’m here with Matthew Stead, who is back in Australia, but not at home. He’s up in Queensland. Or actually, not even on– in Queensland, technically. He’s on an island off the coast of Queensland. Where are you at, Matthew?  Matthew Stead: Uh, Moreton Island. It’s, uh, like a resort island off, uh, off of Brisbane, so beautiful outside.  Allen Hall 2025: Well, you need a little bit of resort time because you’ve been to two conferences, and you spent a good bit of time in Austria after that. So you were at WindEurope in Madrid, and then following that, you went right over to Scotland for Blades Europe. So I wanna hear your thoughts. We’ll start with, uh, WindEurope and what was going on at that conference. It did sound like there was a pretty [00:01:00] good attendance, and some people that I have talked to about it really en-enjoyed being in Madrid. It’s just  Matthew Stead: a bigger city. Um, first time I’d ever been to Madrid, and, uh, yeah, the show was amazing, actually. I was, I was a bit blown away by, uh, I think the OEMs were back out in force. You know, so like the Vestas, Siemens were, um, really– and Nordexes and so forth were really back out in force, so that was really good to see. Um, the, some of the larger operators had really, really strong presence as well. So you could see that, you know, Iberdrola, Res, um, those sorts of companies were, um, really, you know, putting a big effort in and meeting their customers and, um, really showing, uh, the world who they were. So that was really, um, you know, really good to see. There were so many people seriously. Um, the queues for food at lunch were, were, um, one of the major problems. Um, so, um, yeah, it was really a lot of people, so that was really exciting. Um, and I mean, for me, I was [00:02:00]trying to catch up with, with partners and friends and, yeah, it was, it was jam, jam-packed just meeting people in the industry. Um, probably a few other things. So s- you know, SkySpecs and Aerones had a really strong, um, presence there. So, um, SkySpecs and Aerones were, were doing really well. Um, maybe one of the, um, surprises for me, and I know this has been a topic on a few other previous episodes, was there was a lot of interest in bird and bat detection. I, I, I think there had to be, like, five companies that were, were– had really big setups, and it was a really, really big topic around cameras and so forth. So, um, that was a, a big topic. And, um, then there, there was a really, really strong, you know, supply chain, you know, from, from vessels to cables to, you know, repairs. Allen Hall 2025: What was the ratio of offshore companies to onshore companies? I’m always curious.  Matthew Stead: You’re looking through the, the list. Um- I would, I’m only guessing it [00:03:00] was probably about 40% had an offshore focus of some kind. So it was definitely a strong offshore focus. Um, obviously, you know, a lot of onshore, offshore combined companies. But yeah, definitely the word offshore kept on popping up a lot.  Allen Hall 2025: Because Spain is mostly onshore. Like, um, like 99% onshore, right? I think it’s a couple of small projects going offshore. Does it look like the onshore business is gonna pick up, uh, just in terms of the activity on the floor in Madrid?  Matthew Stead: Uh, yeah. Um, I, I think, you know, like I said, you know, those big operators like the REZAs and the Iberdrolas and, and the OEMs, I, I think it’s just a given that, um, you know, things are buoyant. Um, well, they appear to be definitely very buoyant. Uh, I think we’ve heard, you know, some of the positive, um, financial news from a few of the OEMs recently. So yeah, yeah, it seems like o- onshore is, is maturing further, further, further. And so you went straight  Allen Hall 2025: from Madrid, right, to [00:04:00] Edinburgh, Scotland. That was a change in weather, I would assume. Uh, probably about a 20 degree Celsius difference. 25 down to 15, yes. Whoa. Okay. Yeah, that’s a good bit. Uh, but the Edinburgh conference, that’s the first time that Blades Europe has been to Edinburgh. I, at least I don’t remember them being there before. That tends to be a more technical conference than Wind Europe. Uh, the, the Blades conference is obviously focused on blades, and all the relevant experts in Europe do tend to show up there. What were some of the hot topics at Blades Europe this year? Matthew Stead: Yeah, I think it was, um, an interesting conference. Um, I, I’d been to Blades USA, so I was able to contrast, um, Blades USA a little bit. I think probably the differences here were, yeah, there was definitely some strong, strong, uh, experts there, like you say. Um, you know, Birgit, um, our friend was, was in attendance and a few of her colleagues from Statkraft. Um, I think, and or, uh, actually ORE Catapult, the, the [00:05:00] UK research, um, offshore renewable energy research, um, they did some great presentations. I really, um, they really shared some really good insights. So, um, ORE Catapult were talking about life extension and, um, you know, looking at the, the fatigue on blades and, uh, how they’re, how they’re going to perform and life extension. So some great stuff from ORE Catapult there. Probably another key topic that came up was around, uh, sort of related to life extension, but also recycling. The, there was a really good session on the new IEC standard. Um, um, to, you know, full disclosure, I was actually on the panel. So I, I thought it was a great panel. But, um, the new IEC standard for blade operations and maintenance, um, is really well a-advanced now in its development. Um, very strong risk focus, you know. So depending on the risk then drives your, your blade O&M program. [00:06:00] Um, so that was a, a great talk as well. Uh, and then maybe finally, um, something close to my heart, um, I think the, the, you know, the maturity of CMS companies. There actually, there were five blade CMS companies there, which is probably the biggest turnout I’ve seen around blade CMS, um, ever. And so it was good to see that sort of, um, interest and growth, um, and the need for, for blade CMS. Uh, and, um, obviously the last one, lightning. So lightning always an issue. Lots of discussions around lightning, um, you know, through Greece and a few of the, the, the Balkan go- Balkan states. On the blade recycling front, there’s a  Allen Hall 2025: company in Scotland called ReBlade that is involved in some of the recycling efforts. Did they give a presentation of, of what they’re up to at the moment? Matthew Stead: Uh, yes, I think they did. Um, they’re talking about setting up a, a site in a, a [00:07:00] couple of sites, and I think Inverness was the, the location where they’re, where they’re setting up a site. The, um, the port is supportive, so they’re working through those, those, those challenges. You know, getting a site, getting transport and access to the blades. Um, working out when, when the, when the blades will come to them. You know, the storage of blades. Um, the, the end, end uses for those blades. Getting all that supply chain, um, lined up was, you know, yeah, it was, that was quite thorough and quite, um, yeah, inspiring.  Allen Hall 2025: And on the CMS side, what are operators trying to monitor? ‘Cause usually have something in mind that they’re going after.  Matthew Stead: For better or for worse, there’s still some serial, um, failure modes. Um, and so the industry is looking at very particular, you know, challenges that, um, certain make and model have. Um, so root insert failures was definitely one of those, um, one of those topics. Um, and that was actually one of the, the, the [00:08:00] roundtable discussions at, uh, Blades Europe. Some other, um, monitoring around, you know, lightning and- lightning damage and what’s happening with the LPS. That was also, uh, another big topic for, for monitoring. And then a few other sort of general, more, more general, um, you know, natural frequencies of blades and seeing if the natural frequencies are changing, indicating a change in stiffness, which relates to potential damage. So yeah, there was– it was quite a mix of the types of, um, CMS that was discussed.  Allen Hall 2025: Has the digital twin finally died? Anybody talk about that?  Matthew Stead: There’s actually a current call-out for a new research project in Europe around digital twins. So, um, yeah, one of the larger, one of the larger operators is, is putting, pulling together a team to talk about digital twins, so-  Allen Hall 2025: I, I think this is one of the more difficult things to do, but just because you’re dealing with a variety of blades and blade factories and unique issues that pop up that are…[00:09:00] You, you really can’t model until after they happen. And after they happen, everybody knows about them anyway. So what’s the point of the digital twin if you can’t detect things early? It, it, it is a great concept, but hard to implement.  Matthew Stead: Yeah. And why? Why would you do it? I mean, you, you’re only gonna do it if there’s a benefit, and what is the benefit? So, but I think, uh, actually at Blades Europe, digital twins was not really a topic. And maybe one thing I forgot to say is that the, um, Wind Power Lab did a, a good, um, presentation on carbon blades as well, so.  Allen Hall 2025: The, the carbon blades are, is a very good discussion, just because the trend has been lately to scrap blades and bring new ones on site. And the carbon can be difficult to repair, or it takes a long time to repair, and you just don’t have the manpower or woman power to go out and fix it. So the, the fastest option is to build a new blade. But it does leave a lot of blade waste, which is where the industry is not going. Uh, recyclable blades, which is [00:10:00] in process at the moment, will make that easier, but you just don’t wanna be recycling blades. You like to be able to repair them. Composites are repairable. And it’s, it is so odd that they, they wanna continue on that pathway, but we’ll see. We’ll see. You don’t really learn the lesson until you do it.  Matthew Stead: Um, however, you know, the, the presentation on carbon blades was, um, you know, highlighted a lot of the challenges, but also highlighted some of the positives and the, you know, how they do help. Um, and so there was a lot of support for carbon blades, but there’s a lot of unknowns and, um, and there was a lot of discussion around how do you even test if the LPS is working. Uh, it’s just impossible. So, you know, traditional methods on carbon blades, yeah, it just don’t work. So, um, but there was a lot of support that the carbon does bring benefit. But yeah, I agree with you. There’s a lot of challenges there.  Allen Hall 2025: That’s one of the things we learned years ago back in the late ’80s, early ’90s when we, at least in, in the [00:11:00] States, started building a number of carbon fiber aircraft. And the repair situation and dealing with repairs in, in remote locations became difficult. And you’ve learned how much training it took to keep an industry running, and you’re starting from zero for a lot of places that all he had worked on was aluminum. It, it’s a completely different world. You’re, you’re training tens of thousands of technicians around the world. You weren’t planning to go do that, and now you are. So it just, it adds to the cost.  Matthew Stead: It also ties into the OEM, um, you know, providing, you know, details on how to repair those blades because they’re not, they’re not just a standard item, so-  Allen Hall 2025: No, you, you don’t wanna be grinding into a protrusion if you can avoid it. It- you’re just never gonna get it back into that original form because protrusions are in some part magic. And taking a grinder to them is not gonna… It’s breaking the magic. All the magic will be leaving that protrusion when you do that. Yeah, very [00:12:00]difficult. Delamination and bond line failures in blades are difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production. CIC NDT are specialists to detect these critical flaws before they become expensive burdens. Their nondestructive test technology penetrates deep into blade materials to find voids and cracks traditional inspections completely miss. CIC NDT maps every critical defect, delivers actionable reports, and provides support to get your blades back in service. So visit cicndt.com because catching blade problems early will save you millions. Well, as we know, the wind industry has long been dominated by a handful of European and American turbine makers, uh, particularly in the, quote-unquote, “West.” Uh, but that landscape may be [00:13:00] shifting. Suzlon, the Indian turbine giant that nearly collapsed under about a $1.5 billion of debt just a few years ago, is back. The company has unveiled a new turbine platform aimed squarely at Europe, and says it will build its first factory on the continent if it wins enough orders. Vice Chairman Girish Tanti, uh, delivered the announcement at the WindEurope conference in Madrid, where Matthew was Signaling that Suzlon believes its time has come. And since you were there, Matthew, did you hear any news on the floor, any discussion on the show floor about Suzlon entering Europe?  Matthew Stead: Well, actually, yes. So, um, um, there was actually a good, uh, contingent of Suzlon people at, uh, Blades Europe. So, uh, they attended, uh, Wind Europe and then Blades Europe. Um, and I, you know, I was able to have a bit of discussion with them. I think, I think, uh, they were quite optimistic about, um, [00:14:00] you know, moving back or moving into, into Europe in terms of manufacturing. Um, however, there was an element of skepticism. Am I allowed to say that? So they, uh, were, they were not completely, um, convinced that it’s gonna happen, but, uh, they were certainly excited by that. It was definitely a, a clear possibility, but not a given.  Allen Hall 2025: Well, they have a, a new platform called the Blue Sky platform, um, which will have, I think, two turbines here, a 5 megawatt and a 6.3 megawatt, which is squarely aimed at Europe and also the United States, for that matter. And building a factory, though, doesn’t make a lot of sense if the cost driver for a factory in Europe is the European employees, which it tends to be when you hear the discussions about the cost structure, it’s about the employees. I’m not sure why Suzlon would make blades or nacelles in Europe unless they could avoid tariffs or taxation, because India is a very [00:15:00] cost, uh, driven, uh, manufacturing facilities writing country. So why would you wanna go build another expensive factory, probably in the realm of a couple hundred million pounds, uh, if you’re gonna go do it? It probably doesn’t make any sense to do that as well as just selling turbines into Europe. It seems like the easier path.  Matthew Stead: Yeah. And then you’ve got all the, like, the quality control challenges and, you know, you get the cultural challenges. So yeah, to be honest, I don’t qu- I don’t quite understand the logic behind that either. Um, maybe there’s, there’s some things that we don’t know about behind the scenes in terms of tariffs and other, other incentives that we don’t know about.  Allen Hall 2025: Would you see operators taking, uh, a Suzlon presentation and maybe even writing plans for developing with Suzlon turbines in the next couple of years? Is that a, a feeling that Europeans would, would do that, or is Vestas mainly and Siemens Gamesa so strong in Europe that it doesn’t make any sense unless [00:16:00] you’re in sort of the periphery countries of Europe?  Matthew Stead: I mean, my first exposure to a wind turbine was a Suzlon turbine in Australia, and there are many, many, many Suzlon turbines in Australia. And they’re all, they’re all still working. They’re all still reliable. So I mean, from a reputation and reliability and, um Yeah, history point of view, I can’t see why not. I mean, you know, uh, the operators will see that, you know, they’ve proven themselves. They’re not new kids on the block. Um, and so why wouldn’t an operator think about it? Allen Hall 2025: Well,  Matthew Stead: in  Allen Hall 2025: this quarter’s PES Wind magazine, which you can download for free at peswind.com, there is a nice article from Muelhen Wind Services, and that is a growing company. A lot going on there. Our friends at AC883 just joined Muelhen a f- few months ago, and is being part of that conglomerate. And, and we know that obviously building wind farm used to mean [00:17:00]consulting with dozens of contractors, and this is where Mue- Muelhen has really s- stepped into the breach here. So from blade repair at one company and heavy lift cranes at another company, all that had to be managed separately. You’re calling s- different companies all the time. And watching asset managers and site supervisors do this, uh, it is a thankless job. Well, Muelhen’s trying to change that a little bit, uh, and they’re saying that that model no longer works, and I totally agree with them. It’s insane. Uh, but so Muelhen has consolidated six specialist firms under its one brand, and covering everything from port pre-assembly to long-term operations and maintenance across Europe, the US and Canada, uh, and Asia-Pacific. Its CEO, Søren Hoffer, uh, puts it plainly, “The next phase of wind will not be won by turbine size alone. It will be decided by the supply chain’s ability to execute.” Boy, [00:18:00]couldn’t say truer words. Uh, I’ve worked with Muelhen or my company, Weather Guard Lightning Tech, has worked with Muelhen on a couple of projects over the years, and we’ve always had, uh, great service from them, and we have talked to a number of operators that love them, that love using Muelhen. So it’s not a surprise that they’re trying to grow and expand and make life easier for the operators.  Matthew Stead: Sounds like a brilliant move, really. I mean, you know, pulling all these sort of things together is, is a real challenge, isn’t it? I mean, coordinating all these subcontractors, um, getting to turn up at the right time, and yeah, I mean, it just sounds like a brilliant move, and I think that we need more, more, more efficient service companies to service the growing fleet. So the more they can get organized, the better.  Allen Hall 2025: Yeah, the scale matters here, and the expertise matters. As we’ve have a couple hundred thousand turbines that are [00:19:00] operating in the, quote-unquote, “West,” it does make sense to have a larger player that has seen most of those turbines and has some experience with them. It’s always the scary scenario when you’re working with a new company. Have they been on this turbine before? Do they know what they’re doing? Do they know- Lockout tagout. Even simple things like that come to the forefront. And the, the trouble is on some of these smaller companies that are in that business is that, uh, you just don’t get the level of service, you don’t get the level of response, you don’t have the horsepower if something were to, to go wrong on site. They don’t have the cash to, to bring in a second crane or another crew to get this job done. It, it does become scale at some point. And, uh, for a long time in the wind industry, particularly United States, it, it has been a lot of, quote-unquote, “mom-and-pop operations,” and those are slowly getting acquired by the likes of Muehlhan. I, I, I think this is inevitable at some point. Uh, from the asset owner’s, uh, desktop watching this go on, [00:20:00] how do you see, you know, a large operator interfacing with Muehlhan? Are they gonna do just one-stop shopping at this point? They’re, they’re not gonna have three or four different companies to work with, that they’re just gonna lock into, uh, Muehlhan? ‘Cause, uh, that’s what I see.  Matthew Stead: Yeah. I, I think, you know, from the, the WOMA Conference in, in Melbourne, we saw a bit of a, bit of a shift towards, um, outsourcing, at least in Australia Pacific region. And I mean, if, if you’re gonna outsource, um, you’re, you’re probably gonna join up with a, a Muehlhan, um, equivalent. So, you know, that way it just takes some of the risk out of, out of it, so it, it sort of makes sense. Um, the other observation I’ve heard is that, you know, because of the seasonality of blade repairs, it’s really hard to keep hold of, um, blade techs. And so if you’re a global company, you’ve got at least some opportunity of using the ses- seasonality and keeping hold of the good techs and, um, you know, so, you know, you know, summer in, in North, North, uh, America, and then, you know, summer in [00:21:00] Australia. So it, it, it allows these company, allows these companies to keep hold of their good people.  Allen Hall 2025: Yeah. And that, that’s always been the yearly problem, right? That you have a, a crew of a couple good crews in the summertime, and you come back the next summer and it’s a whole different group of people and yeah, that, that, that’s trouble for the industry. Well, a- and it’s good. It’s fi- it’s finally good to see this happening, and I know, uh, we’ve talked about it internally here at Weather Guard of who to work with and who to partner with. We like working with companies that have scale, and I think we’re finally there. So it’s really interesting to see this article from Johan in PES Wind. So if you, if you haven’t read the article, you should go visit peswind.com and take a look. There’s a lot of great content in this quarter’s issue, and y- you don’t wanna miss it. So go to peswind.com today. As wind energy professionals, staying informed is crucial, and let’s face it, difficult. That’s why the Uptime podcast recommends PES Wind magazine.

Whether you’re an industry veteran or new to wind, PES Wind has the high-quality content you need. Don’t miss out. Visit peswind.com today. So when, when the energy prices spike like they’re happening right now, uh, the Iran war being one of the main drivers, and obviously gasoline prices have jumped quite a bit, here’s what happens. The China’s clean energy sector goes to work, and they’re racing to make connections and make sales. As electricity prices jump up, gas prices jump up, everybody wants to try to find a cheaper way to provide energy to their countries or locales. Uh, China’s there to offer it. So it’s solar panels, batteries, EVs, and even wind turbines are, are looking for homes out of China. Uh, for European wind professionals, [00:23:00] the most important part comes from Mingyang, right? So they were unable to get a production facility in Scotland, but they haven’t given up yet. They are still searching for a home somewhere in Europe. And as of today, I don’t think they’ve found it. They’re s- I think they’re still looking for some country to host them. But how long is that gonna go on, Matthew? I, I think with the domination of Vestas and Siemens Gamesa in Europe and Suzlon trying to make an entry, will Mingyang and other Chinese manufacturers eventually find a home?  Matthew Stead: It’s interesting. I think, uh, if you look at the airline industry, you’ve always had premium providers, and you’ve always had low-end providers, and I think there’s always a place for all of them. And so I re- I reckon they’ll find, I think they’ll find their place in, in the market and just, you know, it might just take a while. But they’ve got the strength, haven’t they? They’ve got the product. They’ve got the strength. So it’s just a matter [00:24:00] of time.  Allen Hall 2025: Yeah. I, I, I d- I do think eventually it will happen. But Vestas and, and Siemens Gamesa have done a pretty good job of controlling it, and wind Europe, honestly. Wind Europe has not been a proponent of a Chinese manufacturer in Europe, so that generally will help slow down any business plans they would have But at the same time, there’s a lot of opportunities around the world that’s not necessarily in Europe, right? South America has strong ties with China. They’re– And Chinese companies are, are starting production in China. There’s a lot th- things happening there. You’re gonna see that in Africa and other places. So it doesn’t necessarily have to happen in Europe, which is, I think Europeans and Americans think, “Well, we can’t have China in those locales.” Fine. But it isn’t like China doesn’t have other opportunities to, to sell turbines or solar panels or batteries. There are plenty places on the planet where  Matthew Stead: people that  Allen Hall 2025: need  Matthew Stead: lower cost energy, and they’re gonna find them. Um, I did attend a, a panel [00:25:00] discussion on Türkiye, um, and the growth, and there was a lot of growth in Türkiye around onshore and offshore. And so maybe Mingyang, that might be a, a place, um, for them to, to start, you know, on the doorstep of, of Europe. The stepping stone, so to speak. Stepping country.  Allen Hall 2025: Is there risk in that, uh, uh, if, uh, uh, Mingyang decided to put a plant in Türkiye? Is, does that come with some political aspect? Because I, I, I don’t remember. Türkiye t-tends to play, uh, uh, k- kind of like Switzerland in, in terms of working with different, uh, political systems over time. Yeah.  Matthew Stead: I, I’ve had a bit more to do with a few, a few, um, sort of organizations in Türkiye recently and, um, you know, it’s highly professional, highly, you know, logical, and so I, I can’t see why it’d be a challenge. So I think, yeah, that stepping stone into Europe might be a, a logical way to go. Well, maybe  Allen Hall 2025: we’ll see that in the next [00:26:00] couple of months. I don’t know. There’s gonna be a lot to happen there. There’s so much money being spent in Europe on renewables, wind, solar, battery, all the above, that there’s plenty of opportunity, and every company that has a product that’s gonna be trying to sell it in Europe right now. It’s a smart move. Absolutely.  Matthew Stead: I think the other thing that we’ll probably be talking about a little bit more is EV trucks or, you know, electric trucks.  Allen Hall 2025: You think so?  Matthew Stead: I reckon we’ll be talking more and more about electric trucks.  Allen Hall 2025: Does Europe even have a, a le- a real true EV tractor-trailer, large truck? What do they call… I guess they call it a lorry.  Matthew Stead: I don’t think yet. But that’s why I’m saying I think this is a topic that’s gonna raise itself. Um, I’ve, I’ve seen some numbers recently which says that it’s a bit of a no-brainer to go from diesel to, um, to battery now.  Allen Hall 2025: So is Tesla gonna be the, the winner there just because of their, I don’t even what they call it, the Tesla truck? Is that what they call that now?  Matthew Stead: Not the Cybertruck, the, the truck truck.  Allen Hall 2025: Electric semi-truck. There you go. [00:27:00] Thank you, producer Claire.  Matthew Stead: I think you’ve gotta watch, you know, you’ve gotta watch BYD and a few of the other, the other, um, other companies.  Allen Hall 2025: Do they have something as large as what, uh, Tesla is offering today? Because Tesla is offering a true semi or tractor-trailer  Matthew Stead: I, I, I must admit I’m not a, a huge expert on the topic, but I’m sure Rosemary is.  Allen Hall 2025: She drives the big rigs? Is that what she’s doing?  Matthew Stead: But I think we– Yeah, I think, I think it’s an in-interesting thing to watch because, um, certainly fuel prices in Australia are definitely pushing, um, this idea of, um, electric trucks. Allen Hall 2025: Yeah, diesel prices are really high in the States. I- if they’re high in the States, I can’t even imagine what they are in Europe or Australia. They must be through the roof. So if you have a diesel vehicle, although they run forever and are pretty efficient, the price of fuel is insane right now.  Matthew Stead: And, you know, if you, if you take that a step further into mining, so Twiggy Forest, um, and Fortescue, you know, switching to [00:28:00] electric, uh, trucks and electric mining, yeah, it makes sense. Allen Hall 2025: Does the math work out on that? Uh, obviously Fortescue is taking, uh, really a pretty significant risk in that they’re developing their own electricity generation sites via wind and solar and battery, the whole thing, and they’re converting some of their larger vehicles to electric. Does that hold a big risk, or is this just a financial no-brainer, particularly when diesel prices are so high? Matthew Stead: Yeah, I think it’s a financial no-brainer. Uh, and that’s why partly I think we’ll be talking about trucks because, you know, once the finances make sense, um, there’ll be a faster transition. And I think, you know, Fortescue is not a silly company.  Allen Hall 2025: Fortescue is willing to dabble, right? So they’re willing to, to see where the technology is and spend a little bit of money and possibly it works out, right? I think there’s– you have to take a little bit of risk if you’re in that business because you are spending so much money on fuel. [00:29:00] You can spend a couple million dollars playing in different areas to pick an eventual winner. Obviously, they’re gonna– Well, it’s not obvious at the moment, but it, it seems obvious to us being on the electricity side. Electricity is gonna be the answer. Renewable energy is gonna be the easy way to do it, the lowest cost way to do it. There you go. Go do it. Well, American Clean Power’s event, uh, which is in Houston this year, will be happening June 1st through the 4th at the convention center downtown in Houston. It’s gonna be warm, everybody, so if you’re traveling from a cooler country like Denmark to Houston, bring something cool to wear. It will be warm in June. It, it– Houston is just a very warm place, and it’s quite humid, so it’ll, it’ll be a, a unique environment. However, it does sound like there’s gonna be a, a, an– A number of interesting companies and a lot of people that are attending that event this year, and one of them is gonna be Matthew and EOLOGIX-PING with Weather Guard Lightning Tech will [00:30:00] both be down at the event in a booth and seeing everybody and, and, and meeting a whole bunch of, of, uh, new people that are getting into the industry, which is, to me, is always the fun part. Like, we just meet so many really fun people. Uh, and Matthew, you know, we had a discussion internally about that, like, uh, our, our new, uh, chief commercial officer, Nikki Briggs, has been commenting. We’ve been talking to so many operators around the world, and after every, uh, little meeting briefing that we have, we do a post-briefing, and she goes, “They were so nice.” And I s- yes, Nikki, the wind industry people are fantastic to work with. Like, they’re all focused on doing something positive, and they’re trying to, to do it the best that they can. And there’s a lot of constraints to it, and they’re making a number of hard decisions. But when we all come together at American Clean Power here in the States, hey, we can kinda commiserate and [00:31:00] talk about what’s happening and catch up. And I feel like we need a little bit of catch-up time in this industry, particularly here in the United States.  Matthew Stead: Yeah. Yeah. I, I think, um, I, I definitely agree. And I, I found, you know, previously I used to work in the construction industry and work with engineers and, you know, transport, blah, blah, blah, blah, blah. And actually, I found that the renewable industry, there’s a lot of really open people, really happy to have a discussion, um, not the big egos, so I completely agree. And, um, I’m thinking back, um, I first met people in the wind industry in, you know, around 2012, 2013, and, you know, I still know a number of those people and really appreciate catching up with them. Um, so actually, Berend van der Pol was probably one of the first, and, uh, Birgit Junker was, um, maybe one of the second, so yeah. And I’m definitely looking forward to ACP.  Allen Hall 2025: If you’re, if you’re down in Houston at American Clean Power, definitely stop by a- and say hi to everybody from [00:32:00]EOLOGIX-PING and Weather Guard Lightning Tech, and hey, learn about all the things that are going on because both companies have new products that’ll, were gonna be announced at the site. Uh, we’re already getting inundated with requests on the Weather Guard side. It’s insane. We’re telling people, like, “Slow down, slow down, slow down. We’ll, we’ll, we’ll talk to you about it when we get to Houston.” But, uh, expect a very attentive audience this year, which is exciting.

Allen Hall: So we’re in Dunlap, Tennessee, not too far from Nashville, uh, and also close to. Chattanooga Chattanooga, and we’re in the Smoky Mountains ish region. We’re Alfred Crabtree: no, we’re, we’re, you could consider it Appalachia for sure. Sure. Okay. Uh, we’re on the, in the valley called the Seche Valley, uh, which splits the Cumberland Plateau. So we’re, we’re in a valley and we have hills a thousand feet above us here. Yeah. Either way. It’s beautiful. Joel Saxum: Yeah. It’s a great drive in here. Alfred Crabtree: Yeah. It’s a unique place. Yeah. Allen Hall: And we’re at Blade Repair Academy, which, uh, if you’re not familiar with Blade Repair Academy, you should be. Uh, because a lot of the good training that happens in the United States actually happens to play repair, repair Care blade, repair academy. Uh, yeah, it’s been a long week at uh, OMS this week and we got the introduction today. This is the first time we’ve been on site. That’s right. And, uh, we wanted to see all the cool things that are happening [00:01:00] here. And it really comes down to technician training competency. Working with blades, working with tools, knowing what you’re doing up tower when you’re on the blade, which is hard to train. It’s really hard to train, and both you and Cheryl have a ton of experience being up on blades and repairing blades and scarfing and doing all the critical features that have to happen to make blades work today. It’s a tough training regimen. There’s a lot to it and a lot of subtleties that don’t always get transferred over from teachers to students unless you have. Done it for a number of years. You wanna kind of just walk through the philosophy of Blade Repair Academy? Alfred Crabtree: Yes. The, uh, you’ve, you’ve outlined quite well some of the issues. The environment where we work is very hard to take a ti the time to put somebody through a training regimen. We’re so constrained by weather windows and then. You know, even if the weather’s nice, lightning can come, wind [00:02:00] speeds can cut off your workday. So production, production, production is what’s important. And Cheryl and I both come from the rope access method. And in the rope access method, 95% of the time you’re up there alone. And if you’re up there and you’re producing, you’ve got your blinders on. Speaker 2: Mm-hmm. Alfred Crabtree: And you’re not ready to share with somebody else what to do. Speaker 2: Mm-hmm. Alfred Crabtree: With the basket or platform, you can have two even three people up on Blade, but it still has all these constraints of get the job done, get the job done. There’s a lot of stress up there. And having the bandwidth to take on new information or to challenge some preconceived notions or try, that’s not the place to do it. So knowing that. Blade Repair Academy is built so that we have an environment that simulates all of the up tower stuff without being up tower. And you’re gonna have the time you need to invest in your learning without consequences. Right. So it’s a very much a [00:03:00] about creating the right environment to uptake the new information. And we have found a lot of help from. Manufacturers and suppliers in the industry to sponsor us because obviously it behooves them to have their materials in the hands of trainees. So we’re also able to help companies come up with, uh, new solutions, try new products. Speaker 2: Mm-hmm. Alfred Crabtree: New, uh, you know, what’s the best practice. For this, if you’re up on Blade and you have a way of top coating and you get a new product and your way of top coating doesn’t suit that product, well chuck it down. I’ll never touch it again. Yeah. Because I did not perform well here we can, we can give you training. We have, of course, been trained by the suppliers about what’s the best product to use, what’s the best way to go about things, and then, and then we can disseminate it. So that’s the fundamental reason why the space is. Is [00:04:00] what it is. Joel Saxum: Yeah. And I think that that’s, that’s a good segue to be honest with you, right here, right behind these doors you have a classroom. That’s right. Right. So in this facility, all composed in one, we have a classroom here we have your additive and subtractive. I liked how you said that to us when you’re giving us the tour. Uh, but we’ve got a, a grinding booth basically over here and we’ve got, um, a layup area here where you can teach. 16 people at a time. Alfred Crabtree: That’s right. Yeah. That would be max Joel Saxum: for sure. Alfred Crabtree: Yeah. Sheryl Weinstein: And in a vertical surface, so, ’cause all the stuff that you’re doing in the field, right, is always in a vertical surface. Mm-hmm. So there’s a, there is a big difference between working where gravity is sort of against you, especially with larger laminations and things like that. So being able to do your training and simulate the same, a similar way that you would work in the field is pretty critical, I would think. Allen Hall: And actually working on. Actual repairs. Simulated repairs, yeah. Mm-hmm. Now, don’t explain how you created them, because I know secret sauce. It’s a secret sauce. Yes. But I did look at the blade [00:05:00] damage. It, it looks exactly like a lightly strike. Yeah. Which a predominant amount of repairs are about, unless there’s, you know, serial defects, as Cheryl has pointed out numerous times, but. Being able to repair something that’s quasi real is critical because we’ve been to other places and the repairs are, well, I’ll take a hammer and I’ll hit this and, okay, sure you got a DA, you gotta repair that. But that’s not real. And getting, getting the people to use the tools in the right way, vertically Speaker 2: mm-hmm. Allen Hall: Is the key. Because although the, the, the article, the test sample isn’t moving around like you are up on a blade, it’s still difficult. And unless you have the proper techniques and the approaches, yeah, it’s gonna be dang near impossible. We explain some of the blade repairs that Joel and I have seen more recently is like. It’s a little rough and it shouldn’t have to be so rough because it is a skill that you have to learn and acquire over time. But you have to know the fundamentals. That’s what Blade Repair Academy is here to teach you those [00:06:00] fundamentals. Like, yes, it’s gonna take time, but if you work it this way, at least you’re gonna be successful. Alfred Crabtree: Yeah. And if you’re managing a team of employees who are doing this, it, it would be great to have the insight of what your teams. Strengths and weaknesses are, yeah, you can figure out how to deploy people, but also how to, you know, maybe fix some of those problems. Mm-hmm. Our panels that you brought up are standardized. Everyone looks exactly the same. It’s the exact same makeup, and we standardize the damage. So when somebody has to repair damage here, the core removal size is the same on everyone. That way when we’re comparing the reports, you can actually have a apples to apples comparison of the, the trainees. Outcome. Speaker 2: Mm-hmm. Alfred Crabtree: And now you, you know, in, in the model that you talked about where people will go to a, you know, their junkyard of blades and they’ll find spots on blades to put their eight guys on. Those eight people are not gonna be doing the same repair. And even if they are collecting data, what are you [00:07:00] comparing? It’s not Joel Saxum: apples to apples. Yeah. It’s not. Alfred Crabtree: So we really tried to start from the beginning, fresh with a whole new idea of how to approach this. Mm-hmm. By not being attached to an ISP, we don’t have to deal with. Oh, here, use all our leftovers. Yeah. Yeah. That’s your training budget. Yeah. Yeah. And oh yeah. We, you know, we’re an, we’re a owner operator, so yeah. Go work on that blade in the grass. Mm-hmm. That those limit what precious time we have available to train. Yeah. So this thing from the ground up is about. Making as much advance in the skillset and understanding that technician in the, in the week that they’re here. Joel Saxum: I think that was a really cool thing we touched on as well. Your, your team here as well, Cheryl. Thanks for traveling up to, to hang out with us. Offer some insights too. But you guys, because you’ve been in the people that have developed a curriculum yourself, Cheryl, your, some of your team sitting over here, uh, and, and people around the industry that have helped out with the place, you have the ability of like, okay, we have. Eight brand new technicians. Let’s make [00:08:00] sure we walk through how to measure from the trailing edge to the blade center up, mark this thing out, these kind of things all the way to some stuff that I didn’t really think about that much. Like I’ve used an angle grinder before, right? But I’ve never looked at five different ones and decided which one would be the best for my hands. Thinking about it up on the blade, how you’d handle it with your fingers, these kind of things like, I was like, man, that’s, those are real insights that you’re not gonna get to learn. Like why put someone up to let them have a whole season or a whole summer, two summers figuring out how to hold a grinder? Well, when they can learn from someone that’s been doing it for years and years and years and can teach them these things. So from advanced or from very beginners learning fundamentals to advanced training, you guys have gotta cover here. Alfred Crabtree: There’s something here to glean for everybody, and even if you are a well experienced technician, maybe what you’re gonna get most is learning how to talk the language of the new techs and the new hires who are getting the. Introductory course training. You know, our, our el our basic course is called support. It’s 40 hours [00:09:00] and it’s really about making, uh, an employee who can support a lead. And then if that person follows up with the lead training in a whatever interval of time of their choice, which is kind of another benefit here, we can train you any week of the year. That is where we start to really get this, we call it the retention vortex. Right where we layer up technician training and somebody who’s had level two now gets a level one with them. Now there’s some synergies. Now they’re getting some really efficiencies. A commonality of language, a commonality of process, you know, eliminating variables. Uh, and that’s how you’re gonna have to build new net capacity and build new teams Allen Hall: and that common language. Is really unique, but that comes from your experience in the field, mostly at rope partner, where you both really got your teeth in this industry. Speaker 2: Mm-hmm. Allen Hall: But communicating to one another correctly so you can pass along to the next crew or even explain what you did to the engineer, the. Properly [00:10:00] there is. There is a culture to it. There is a language to it, and you just don’t pick that up. By going from wind turbine to wind turbine. You pick it up in training from someone who knows how to do it. It’s really critical. Sheryl Weinstein: It’s pretty critical to have baseline training. I think it is also very important to follow it up with field experience and skills building because every blade model is different. Every repair is different. You’re always gonna encounter something that deviates from that like standard approach to your repair. You have to kind of know how to problem solve, and that kind of only comes with the field experience, but having a more standardized training to start with, it’s something that industry doesn’t really have and is really needed. I think across the board it also helps, you know. Owner operators or even OEMs kind of track their ISPs and understand what level of text do you have, what experience do they have and how, how does that differ across their different [00:11:00] levels? If we have one ISP training one way over here and another one training another way over here, and they have different sets of certifications. It’s really hard to keep that all together and evaluate it as an owner operator or an OEM, you know, using a vendor. So I think having a place like Blade Academy that’s agnostic and separate from like, you know, the actual ISP really helps to standardize that a bit more. Allen Hall: Yeah, because the key is we’re getting to, well, we’re gonna cross a hundred thousand turbines in the United States pretty quickly. Yep. Joel Saxum: Before 2030, or probably rated about 2030. Allen Hall: Right. That’s. Soon. Mm-hmm. How are we gonna manage that? And there’s a lot of new people coming into the industry, obviously. How are we gonna train ’em up properly? How are we gonna communicate to one another? And there’s just so much movement in the industry. I. It makes it hard, I think, because weirdly enough, I think ISPs develop their own little culture about how to deal with things, and then they hop to the next company and it’s a different language. Exactly. And that needs to go away. Yeah. There’s a, Alfred Crabtree: there’s a branch of business that’s [00:12:00] OEM centric and there’s a branch of business that’s asset owner. Yeah. Post warranty. And those are really two different things. And, and there’s a veil of secrecy between one and the other. Yeah. And we kind of feel here at Blade Repair Academy that we’re like this polyglot that can talk to everybody because we don’t have, we’re not an ip You’re not competing, we’re not an O You’re not competing. Yeah, we’re not competing. But we, we, you know, we have the, we wanna provide this data as a clearinghouse. You know, we talk about certification in the non standards. Well, the way we deal with it is we’ll give you a certificate. And it’s got our brand on it. But you know, what does that mean? Yeah. What? That And $4 will get you a Starbucks the way we do it, maybe not even then. Right? The way, the way we, not four bucks Sheryl Weinstein: for Starbucks, maybe 10 Alfred Crabtree: and a half hour wait in the line. But the way you know, what we do is we provide you with a deliverable. We knew, we knew that. Okay. Our certification is, you know, ether. Speaker 2: Mm-hmm. Alfred Crabtree: But [00:13:00] this report. That everybody who comes through here generates that you can compare. Now you’re gonna have to go to work and study these reports when you get ’em as a deliverable. Speaker 2: Mm-hmm. Alfred Crabtree: As a, you know, an employer, but we we’re giving you what you need. Mm-hmm. To make some decisions about what do I have to work on, what else do we need to improve upon? Allen Hall: Yeah. Not everybody’s built for this job, but you wanna be able to suss that out. Earlier rather than later. Yeah. Right. I mean, there’s other things to do with wind turbines that don’t evolve blade repair. And if they don’t necessarily have the skillset or the comprehension to do some of these more complex things, maybe blade repair is not it. Right. But rather know that now. Yeah. Right. And the Blade Repair Academy is a place to do that because there’s a standard there, right? Mm-hmm. And I, I, as Joel has pointed out, yeah, there’s a lot of erratic training that goes on. Mm-hmm. You can’t compare student A to student Z. Blade repair academy. You can. Alfred Crabtree: We can. Mm-hmm. Right. Allen Hall: And if, if I’m an ISP, I want that. Sure. I want you to tell me [00:14:00] who’s on top and who’s kind of the middle so I can make decisions about where to deploy ’em and who and who to put ’em with. Joel Saxum: Yeah. ’cause at the end of the day, every ISP, uh, every ISP that’s trying to grow and scale effectively is trying to do that at the end of the year, right? Yeah. They’re looking through, they’re grading their technicians, finding out who’s the next lead, who’s this, who’s that? But this is a great way to do that, sort them through in a controlled setting. I mean, we sat in, in your training facility in the actual classroom here, and you walked us through some of the online, the online training platform that you have built. Some of the things the students have to do before they get here, and then kind of how you walk ’em through things, and it’s impressive. It’s good stuff, right? So when you have that combined with the both sides of blade repair, subtractive, additive, right? You get to get this, this holistic view of what that blade technician can do. Yeah. Right? And that’s, that’s one of the things you guys offer here, which I think is fantastic. Alfred Crabtree: Yeah. And we’re trying to constantly improve, you know, we’re talking with OEMs about dissemination of operating procedures or work instructions, share with us [00:15:00] work instructions. We’ll build analogs. That we can train to. Mm-hmm. And we can test off of it. We can verify skill sets. You know, we have a lot of serial flaw campaigns out there that are critical. And do we wanna unleash anybody on it or do we want to know that those people can do it? I think everybody wants to know that they can do it, whether they’re the. Technician themselves, or the person writing the checks. Speaker 2: Yeah. Mm-hmm. Alfred Crabtree: Everywhere in that loop wants to Now not everybody wants to pay for it. Yeah. But we all need it. Speaker 2: Yeah. Alfred Crabtree: And so somewhere along the line, you’re paying for it in the forms of our favorite acronym, COPQ. That’s Joel Saxum: right. Cost support, quality. You know, speaking about the idea of serial defects or known problems in the industry and how to prepare people for those, how do you prepare people for those? Well, they gotta get the experience by just. Grinding away Top coat and getting into him. I walked in here and I looked at this blade sample we have here, and I was looking at it and I go, it looks like a 48.7 C Oh yeah. Buddy walks over you like our 48.7 C I’m like, [00:16:00] man, you guys did a good job on, you know, like, so, so I made a lot of money on 48.7, you know, so to walk in here and see these different tickets that you guys have built, you know, carbon plank and different things with carbon spars and hey, we’re gonna do a carbon spa repair. We have this boom, now we can work on it. Mm-hmm. You know, and we’ll Alfred Crabtree: work with you to solve your problem in a really quick, efficient manner. Mm-hmm. You know, I think one of the things that we have is operational readiness. Most people who are training in-house flip their hat around for a couple weeks and train composites. Mm-hmm. In a limited capacity in the warehouse or at the dock at the truck during January. During January, whatever. And then they flip their hat back on and they go deal with it. And I think the hiring situation is so tough. Like working at Height, you probably need to make sure somebody can tolerate working at height. Yeah. Before you invest in composite training, I mean. You have so many things you have to juggle in your particular situation. When do I put money in this person? We get that. [00:17:00] And so we’re open all the weeks of the year. So we can do this at any time. Of course, everyone wants it in the end of first quarter. Mm-hmm. You know, right before the season starts. So we have a, you know, you have to, you gotta schedule with us, but we can really do this anytime. And so you don’t have to one and done and live with it. Speaker 2: Mm-hmm. Alfred Crabtree: You know, it. You can fit the training into your hiring schema wherever you feel fit, and you can hire people. And if there are stars, bring them in for their secondary, they’re execute their lead training whenever you want. You know, so you can, we can be very flexible and in the advanced stages we will make what you need, you know, obviously has to make business sense for us, but we’ll make blades to replicate the problems you’re facing. Sheryl Weinstein: And I think in terms of like what you were saying when you’re working on, you knows whether we wanna call them recurring issues or serial defects. A lot of it is awareness, right? It’s awareness [00:18:00] of understanding the blade structure, at least at a basic level. It’s awareness of understanding what you’re looking at. It’s, you know, we’re only gonna better inform the industry and the OEM if our technicians have a level of awareness to sort of bring up things that they see as they’re doing repairs. So if they notice that, for example, the, the fibers are misaligned, right? That could indicate that that was a wrinkle, and them having that level of communication or documentation will only help then inform the OEM. Like, is this the reason behind that problem? And so I think like. You know, with Alfred and, and the curriculum here at Blade Academy, them kind of, you know, setting a standard for how, how you know, the structure of the blade, the different types of blades you may see, whether they have carbon fiber in them, or you know, fiberglass, UD spars. Where those things are located, [00:19:00] what to be aware of as you’re removing damaged material. It’s really critical to the overall quality and just the awareness of the tech on the blade and that feedback loop that we’re lacking so much in this industry. Alfred Crabtree: Yeah, for sure. Yeah, and we have our boilerplate products that come from, you know, like, uh, Cheryl was my mentor at RP and wrote partner, and she taught me a lot and a lot of the. The, the way we do things here comes from the rope, a rope access paradigm, which, you know, actually is backward compatible because if with rope access, you’re doing things alone. Speaker 2: Yeah. Alfred Crabtree: So if we’ve have ways and, and processes that allow that to happen alone, then when you’re on a basket or a platform with an extra person, you can only benefit Yeah. That much easier. Yeah. Um, it’s where we come from, you Joel Saxum: know, and, and that’s a good point, right? Like when we’re sitting here, rip Blade Repair Academy. Alfred, you’re here. Cheryll, you’re joining us today. These are two X blade technicians that have been on all kinds of blades. They have been up and down on ropes. So it’s training by [00:20:00] trainers who have been the technicians that’s important. Who have seen the problems. Yeah, yeah. You know, who have lived, have lived that road life. We talked, you’re joking about living in hotels, right? Mm-hmm. Like that have done, gone through that, right? So you’re learning from people that aren’t just like, oh, I hate the idea of going to a university and learning HR or something, whatever, from someone who’s never done it in the real world. Yeah. You know, uh, the trainers here have done it in the real world, um, and it shows. Alfred Crabtree: Thanks, man. And you know, the other thing too is our tagline is practical and contemporary. And the thing is, I’m no longer contemporary. Like I left the field years ago. I rely on folks like Cheryl, who’s still in the, in the Blade Services game over there at Skys Specs. She’s on, she’s got a full subscription to the cereal floss that are out there. Joel Saxum: Yeah. Probably the best one in the industry, to be honest with you. Alfred Crabtree: Well, you know. Uh, I think so. I don’t know anything about serial flaw, but it’s, it’s input from the rest of the industry that’s gonna allow this to continue. Otherwise, we’re gonna be, you know, [00:21:00] a 10-year-old standard that isn’t relevant anymore and that’s not what we want to do. So, outreach like Cheryl and I are talking about, Hey, what is it in your product line that should be in our product line? And I want to talk to OEMs and, uh. Owner operators, you know, what is it? What are your pain points? What in your fleet is needing attention? And of course, we’re gonna do all this with the business case, right? Mm-hmm. Like we wanna take LEP products and place them head to head and give a two day clinic or seminar to stakeholders, to purchasers. You know, we wanna give our, our two, our five day course condensed into two days. Where people who are stakeholders who are making decisions about where to place technicians, they should get out here and gr and grind a little bit and get a little empathy for their position. Hard work. The hard work of the Sheryl Weinstein: hard work that it is. Yeah. And then kind of understand Alfred Crabtree: from another side where the [00:22:00] communication breakdown is. ’cause it’s, it’s not all the texts, right? Mm-hmm. You know, they have a, you gotta understand how heavily loaded they are, you know, when they’re in the field. Mm-hmm. Um, so we’re, we’re at the place now where we’re really looking to do some outreach and talk to, uh, regulatory bodies that are starting to come up with standards, right? Like the IEC group met and pro produce a draft standard and they’re gonna work on the repair standard. And that’s a, a little bit of a ways away, but I can’t sit around and wait for, for standards to come to me. So we got this thing started. If you build it, they will come. You guys came, you know, Cheryl came and, um. We we’re really proud of where we’re at, but at the same time, it’s like, okay guys, the rest of the industry, now we’re here. Now you need to know, now you need to take advantage of us. Mm-hmm. And help tell us what you need. So I think the Sheryl Weinstein: LEP thing is a really good call out because I do see a lot of customers questioning what do I choose? How do I know [00:23:00] what to choose? Absolutely. Should my vendor be telling me what to choose? And that’s what happens in many cases, is that the ISP just kind of tells the owner operator. This is what you should use. Well, why, and, and what, you know, how have we ever really sized up like one against the other? Like in any true, I don’t know, study? No. And a lot of the, a lot of the like. Those different types of LEP, the, the companies that you know have these, they don’t have a lot of good documentation on showing like how their products stand up. I mean, it’s kind of, it’s more theory based than anything. I mean, they put ’em through rain erosion tests and whatever, but. It’s, I feel like that’s a tough space. It’s also a very, like, um, a very tough scope of work to have high quality at. So more training around it is necessary. You know, repair companies don’t wanna use their high skilled repair techs for the LEP because they need them for the more complex repairs [00:24:00] yet. The LEP is so susceptible to quality issues, and if you’re gonna pay an extreme amount of money to, you know, put the LEP to fix your erosion, put the LEP on blades, hope for a performance improvement, and then it fails in a year. I. That’s no help to anybody. So these different products, they also come with different price points. Like, can we really value the shell over the coating? I, I just find that this is a tough space. And so doing something like that and doing more training around LEPI think is probably pretty important. Yes. You know, unless the robots are gonna take it over and then, well, even then, I think it’s the only app. Allen Hall: The application, that’s the variable there. And not having people trained up for that particular LEP product is a huge problem because it’s super risky. You’re risking all that money and time and having to do it all over again and removing LEP that has been improperly applied. It’s a nightmare. [00:25:00] Nightmare. Total nightmare. You don’t want that to happen. And I’ve seen sites where that’s happened, getting technicians. Trained properly for the right material and doing that here up in Tennessee is, is the right approach. It’s risk reduction, which is what the industry is in right now. Risk reduction. Alfred Crabtree: Yeah. Yeah, we, we’ve beliefs. That’s a great way to put it. You know, if you hire somebody. We were talking earlier how there are like two models. One is like the New York Yankees, where you’re going to be buying all the expensive free agents. You can poaching people from other, you know, trying to get experienced talent. You’re paying a premium for them, but you aren’t gonna know until halfway through that season how that person is performing. Yeah. You know, that is a lot of. That was, that is a lot of variability that you could control. Mm-hmm. And in a seasonal business, those weeks are really multiplied by two or three. Right. In terms of like the impact on your revenue and your opportunity to make money. It’s risk reduction, like Alan was saying. Yeah. It’s Allen Hall: all risk, right? Yeah. And the, [00:26:00] the way that the industry is moving and the pace at which is moving right now, risk reduction starts to move to the top five years ago. We do a lot of risky things because we’re making money. Interest rates are low and, but today we cannot afford to do that. And if you watch the industry change right now, it is gonna be more focused than ever in having proper technicians on site that they complete the job that they were intended to do. Precisely, accurately, and once, not twice. Once. Yeah. And that is gonna be the marker of the, whether this industry grows or not. Mm-hmm. And that’s why Blade Repair Academy is needed so much. Now, Alfred, how do you interface with the ISPs, OEMs, and the operators in terms of getting people out here? How do they, how do they push that button and say, Alfred, I’m gonna send you 40 technicians next week. How does that, how does that go? I don’t quite have that down Alfred Crabtree: yet. But, uh, you know, it, we talked earlier, it’s a small world. You know, blade repair is small. There [00:27:00] we mentioned if you, there’s a hundred people in the industry you need to know and then you’ve covered it. Um, our, I think we’ve been, we’ve been kind of riding this new wave of like, oh, who’s this new kid on the block? And, and we can kind of be quiet and still are mysterious. And I pop up at a conference and host a round table or whatever. Uh, so far. It’s mainly been our personal network, which is large enough in this gig to, to get people in. ISPs are much more likely to do it small is ISPs are much more likely to do it. Owner operators, they’re trying to build their training centers. They have a little different, that’s a different model though. It’s a different model. Um, they’re, they’re tougher to get. So primarily it’s been ISPs. We have definitely a, a, a curriculum for new hires, right? We call it support, but we’re [00:28:00] reluctant to go sell that to the street or to the public. Like, Hey, enter the industry here, because we don’t quite yet have that, you know, guarantee that people will recognize our certificate and. Use it to hire people. I don’t quite have that system in place. However, I have so much interest from the Department of Labor to support us in creating an occupation. They want us to build apprenticeship programs. We need corporate sponsor, we need a big employer or to to buy in, and then we can create an apprenticeship program. Then we can find public money for people to get some support to get into a new, a new industry. So, well, they Allen Hall: need to come out here. They need to come out to Dunlap. And visit the facilities, talk with you, understand what the philosophy is, see it up close. There’s a lot of them have been to other places. Sure. And see what the differences are here. And, and that’s gonna be the decision maker. They’re gonna see what the product walking out the door is and [00:29:00] go into the classroom and, and get the grinder, right? Yes. Get, get your hands dirty a little bit. Yeah. And realize, yes, this is what I was looking for to begin with. I just couldn’t find it. And I found it here in Tennessee. Alfred Crabtree: Yeah, I, I think you’re right. And, and we, we are slowly, you know, bringing people in that we know, like the reason why y’all are here and some other folks have visited us this week is because o and m was in Nashville. And I was like, come on, come on. We’re only two hours away. We’ll buy you lunch. Come on. Pretty place. Yeah. You have to see this place to understand it because we are sort of, you know, outsiders, right? I mean, we’re, we’re from the, the industry, but we’re not. We’re not a spinoff of any company. We’re not a division of an ISP. We’re totally organic and unique in a, in a part of the world that doesn’t have any wind. So, yeah. Uh, but once you get here, you get it. The economics make sense. You know, we couldn’t do what we’ve done anywhere else as cheaply as we’ve done, which means we feel like we’re super value rich for what you’re paying and for the amount of time that you’re spending [00:30:00] here. Allen Hall: Oh, 100%. Uh. Let’s give the ISPs, the OEMs and the operators, uh, where to go. What’s the website? Where can they find you on LinkedIn? Alfred Crabtree: We’re at blade repair academy.com. Uh, we’re located in Dunlap, Tennessee. We’re on Blade Repair Academy at LinkedIn. I’m Alfred Crabtree. You can find me there. Uh. Allen Hall: Yeah, that’s where you need to go because that’s how the process starts. If you want to have high level technicians that really know how to work on composites and are working with real materials on simulated, but. Pretty realistic damage. Yeah. Weirdly realistic. Yeah. Secret sauce. And to get some sort of validation and to kind of get graded. Mm-hmm. And so you have a, a, a sense of how they’re doing. You’re going to have to go to Blade Repair Academy. You need to get out to Tennessee and you better check it out because I, Alfred, I gotta be honest, this place is gonna get crazy busy [00:31:00] and I’m gonna have. ISPs calling me saying, can you get a hold of Alfred and get me inside? Can you get me in? No, I can’t because it’s Alfred’s deal and Alfred’s gonna run this thing. We’re very approachable and, but very approachable. Keep calling, he’ll answer and take care of you, but it’s gonna get busy because the philosophy here is the right one. Thanks. So congratulations for putting this together and thank you for the invite. Uh, it is been a pleasure to see it. It’s uh, it, it’s great to know that you are around and you’re helping the industry. Alfred Crabtree: Thank you. We appreciate it and you guys are a great clarion for the industry. A great voice. So, uh, those words, uh, right in the fields. And I wanna thank Cheryl too for coming out. I haven’t seen her for a while. It’s funny ’cause today I, on my phone, you know, five years ago today, she and I were here before this business existed as rope partner employees working on r and d week doing infusions. So, uh, Sheryl Weinstein: the space has transformed. It’s amazing. Yeah. You guys have done a, a [00:32:00] really great job. Like I, yeah, I think you’re definitely pushing the industry into a, like a new realm. Bringing something that, that it really needs, you know, that we don’t have at the moment or that we didn’t have. Alfred Crabtree: Yeah, well hopefully, uh, it improves everybody’s quality of product and the bottom line. ’cause uh, you know, that’s what we’ll do. We’ll affect your bottom line for sure. Allen Hall: So Sheryl and Alfred, thank you so much for being on the podcast. Thanks guys. Right, Sheryl Weinstein: thank you.

In the latest edition of the Electoral Road Show with Chris Steyn, Elections Analyst Wayne Sussman dissects this week's by-election results: The Patriotic Alliance (PA) makes history by winning its first ever ward in the Upington area. It took the ward off the Democratic Alliance, and grew its support from a paltry 1% to an “astonishing” 37% of the vote, while the DA fell from 47% to 29%. The African National Congress (ANC) did not have a bad night either: it won a ward off a local party in the Siyathemba Municipality with its support growing from 39% to 51%. The ANC also had a big night in another by-election, this one in North West. “There are people who write off the ANC. There are people who say that the ANC is done. But here in a key township… in a gold mining town in the Northwest, the ANC's vote share is climbing from 72% to 81%.” Sussman notes that the Economic Freedom Fighters (EFF) were not able to capitalise on their Phala Phala victory over President Cyril Ramaphosa. He also 9comments on the engagement of the Independent Electoral Commission's (IEC) with former President Jacob Zuma's MKP in Nkandla as part of its preparations for the Local Government Elections in November.

Podcast: Energy TalksEpisode: #125: OT Cybersecurity Risk Assessments in the Power IndustryPub date: 2026-04-30Get Podcast Transcript →powered by Listen411 - fast audio-to-text and summarizationDiscover methods, findings, and lessons directly from the energy industry In this episode of Energy Talks, host **Simon Rommer **speaks with his colleague Jaron Stammler, OT Cybersecurity Consultant at OMICRON, about how OT cybersecurity risk assessments are conducted in the power industry. Drawing from current experiences in substations and battery energy storage systems (BESS), they walk through how assessments are initiated, structured, and executed in practice. The discussion also highlights the gap between theory and reality, especially when assessments are performed late in project lifecycles due to regulatory or project constraints. Jaron explains the fundamentals of the IEC 62443-3-2 risk assessment process, including system scoping, risk identification, and zone and conduit modeling, while also addressing common challenges such as missing documentation and limited stakeholder availability. Simon and Jaron also emphasize how cybersecurity is an ongoing process and that effective assessments provide actionable insights, prioritized risks, and practical mitigation strategies tailored to each project.

Energy’s brightest innovators. This is the Progress Powering tomorrow. Allen Hall: Nicholas, welcome back to the show.  Nicholas Gaudern: Thanks, Allen. Always a pleasure.  Allen Hall: Well, there’s a lot of new products coming outta PowerCurve. And PowerCurve is the aerodynamic leader in add-ons and making your turbines perform at higher efficiency with less loss. Uh, so basically taking that standard OEM blade and making it work the way it was intended to work. Nicholas Gaudern: Yes. We  Allen Hall: like to  Nicholas Gaudern: think so. Yeah.  Allen Hall: And there’s a, there’s a lot of new technology that you’ve been working on in the lab that you haven’t been able to explore to the, introduce to the world, so to speak. Yeah. And we’ve seen some of it from the inside of, you know, you’re working behind the scenes or working really hard to get this done, but now that technology has been released to the world, and we’re gonna introduce it today, some new trailing edge. [00:01:00] Components. Yeah. That really, really reduce the noise. But they, they look a little bit odd. Yes. There’s a lot of ADON dams going on with  Nicholas Gaudern: Yeah.  Allen Hall: With these. So what, what do you call these new trailing edge parts?  Nicholas Gaudern: So, so what you have in your hand here? This is the Silence edge, uh, serration. So this is our new trailing Edge Serration products. Now, most people, when they think of training restorations, they are thinking of triangles.  Allen Hall: Exactly.  Nicholas Gaudern: These Dino tails. Dino Tails, that’s the Siemens, Siemens name for them. Pretty, pretty standard. You see ’em on a lot of turbines now. Sure. And they work, you know, they do do a job. They do a job. They reduce noise. But like with lots of things in, in aerodynamics, there’s lots of different ways that you can solve a problem and some are better than others. So we’ve worked for a long, long time in the wind tunnel, uh, in the CFD simulations, and we’ve come up with this pretty unique shape. We think,  Allen Hall: well, the, the, the shape is unique and if you, if you look at it, there’s actually different heights to the, the triangle, so to speak. To mix the air from the pressure and the [00:02:00] suction side to reduce the, the level of noise coming off the blade  Nicholas Gaudern: e Exactly. So we have, uh, we have an asymmetry to the part. We have these different tooth lengths. We have, uh, a lot of changes in thickness going on across the part. So it may be a little bit difficult to see on the camera, but these are quite sculpted 3D components. They’re not, they’re not flat stock white triangles. No, no. There’s a lot of thickness detail going on here. We’ve paid a lot of attention to the edges. We’ve paid a lot of attention to these gaps between the teeth as well. So all of this is about trying to figure out what is the best way to reduce noise. And something that not a lot of people will, will admit, but it’s true, is that as an industry we don’t really understand the fundamentals of how serrations work.  Allen Hall: It’s a complicated  Nicholas Gaudern: problem. It’s a really complicated thing. Problem, yeah. Yes. So trying to simulate it in CFD is an absolute nightmare. The, the mesh sizes required, the physics models required are really, really difficult. So what we found is that you’re probably better off spending [00:03:00] most of your time and money in the wind tunnel. Yes. So, so we go to DTU, they have this wonderful, uh, air acoustic wind tunnel, the pool of core tunnel. It’s one the best tunnels in the industry for doing this kind of work. It  Allen Hall: is  Nicholas Gaudern: because you can measure acoustics and aerodynamics at the same time. So this allows us to do a lot of very cost effective iteration for this kind of design work. So we know what’s important. You know, we’ve, we’ve studied all the different parameters of serrations lengths, aspect ratios, angles, thicknesses, all this kind of stuff. And it’s about bringing them together into a, into a coherent product. So this is, this is a result of a lot of design of experiments, a lot of iteration, and combining wind tunnel and CFD to kind of get the best of both of those tools. So,  Allen Hall: so what’s the. Noise reduction compared to those standard triangular trailing aerations. Yeah.  Nicholas Gaudern: So there’s lots of different ways of, of thinking about noise reduction, but I think probably the most useful is the O-A-S-P-L. So this is the overall sound pressure level. Right. Is kind of what [00:04:00]typically you’ll be measuring in an IEC test.  Allen Hall: Right.  Nicholas Gaudern: And that’s measured in decibels, but a way to decibels because it’s important that we’re waiting to what the human ear can actually hear. Right. Perceive. Exactly. So that’s the numbers we report. For the field test we’ve recently completed with Silent Edge, we’re seeing up to five decibels of O-A-S-P-L noise reduction.  Allen Hall: Okay. So what’s that mean in terms of what I hear on the ground?  Nicholas Gaudern: So that is an absolutely huge reduction. It’s multiple times of reduction because you know, decibels on a log scale,  Allen Hall: right? Nicholas Gaudern: So five DB is is enormous. It’s  Allen Hall: a lot. Yeah.  Nicholas Gaudern: And what’s really interesting is that if you have a turbine that’s running in a noise mode, just one decibel reduction. Of power, sound, sound, power level might be three or 4% P loss. I mean, that, that’s, that’s huge. Think about that loss. So if you need to reduce noise by five decibels to get within a regulation, imagine how much a EP you have to throw away by basically turning down the [00:05:00] turbine to do that. Allen Hall: That’s right.  Nicholas Gaudern: So that’s really what the, the business case for these kind of products is. It means you can escape noise modes because as soon as you use a noise mode. You are throwing away energy.  Allen Hall: You’re throwing well you’re throwing away profits.  Nicholas Gaudern: Exactly.  Allen Hall: So you’re just losing money to reduce the noise. Now you can operate at peak.  Nicholas Gaudern: Yep.  Allen Hall: Power output without the creating the noise where you have that risk. Right. So, and particularly in a lot of countries now, there are noise regulations. Yes. And they are very well monitored.  Nicholas Gaudern: Yep.  Allen Hall: We’re seeing it more and more where, uh, government agencies are coming out and checking. Yes. ’cause they have a complaint and so you get a complaint. Oh, that’s fine. Or someone can complain. Yeah. You know, you need to be making your numbers.  Nicholas Gaudern: Yep. And, and the industry needs to be good neighbors, you know? It  Allen Hall: certainly does.  Nicholas Gaudern: Uh, we have to make sure that people are, you know, approving and comfortable with having wind turbines in their backyard. Sure. And noise is a big part of that.  Allen Hall: It is.  Nicholas Gaudern: So yeah. Ap sure. That’s really important. Being a good [00:06:00] neighbor also important.  Allen Hall: Right.  Nicholas Gaudern: Meeting the regulations. Obviously you have to meet the regulations. So this product, um, has been through a really long development cycle, and we’re now putting the final touches to the, to the tooling. So this is available now.  Allen Hall: Oh, wow.  Nicholas Gaudern: Okay. Great. Um, and we’re hoping that in the next uh, few months we’ll be getting even more turbines equipped out in the field with, with the technology.  Allen Hall: So, oh, sure. There’s a, you think about the number of turbines that are in service, hundreds of thousands total worldwide. A lot of them have no noise reduction at all.  Nicholas Gaudern: No. No.  Allen Hall: And they have a lot of complaints from the neighbors.  Nicholas Gaudern: Exactly.  Allen Hall: Trying to expand wind into new areas, uh, is hard because the, the experience of the previous Yes. Neighbor  Nicholas Gaudern: Yep.  Allen Hall: Grows into future neighbors. So fixing the turbines you have out in sight today helps you get the next site. I know we don’t always think about that, but that’s exactly how it works. Yeah, of course. Uh, we need to be conscientious of the people of the turbines we have in service right now. So that we can continue to grow wind [00:07:00] globally and more regulations on noise are gonna come unless we start taking care of the problem ourselves. Nicholas Gaudern: Yep. And another really important thing with Serrations is that you have to design them so that they don’t impact the loads on the rest of the turbine.  Allen Hall: Right. And people forget about that.  Nicholas Gaudern: Yes.  Allen Hall: Can you just, can’t just throw up any device up there. And think, well, my blade’s gonna be happy with it. It may not be happy with that device. Nicholas Gaudern: You have to really carefully understand what the existing blade aerodynamic signature is.  Allen Hall: Sure.  Nicholas Gaudern: How is that blade performing? What is the lift distribution across the span? Yeah.  Allen Hall: Right. Yeah.  Nicholas Gaudern: So what we do, and we, we’ve talked about it before we go and laser scan blades. We build CAD models, we build CFD models so we can actually understand how much lift a blade can take and what’s the benefit or the penalty of doing so. So these serrations are designed by default to be load neutral. They won’t increase lift. They won’t reduce lift. That’s what  Allen Hall: it should  Nicholas Gaudern: be. That’s where you should start,  Allen Hall: right?  Nicholas Gaudern: And maybe there’s some scope to do something else [00:08:00] on certain turbines, but you shouldn’t, you shouldn’t guess. You, you need to calculate, you need to simulate, you need to think very carefully about that. So that’s what we do with these, uh, with these serrations, we go through this very careful aerodynamic design process to make sure that they reduce noise and that’s it. They don’t increase loads, they don’t reduce AP by killing lift. And that’s, that’s an important aspect.  Allen Hall: Well, that’s the goal.  Nicholas Gaudern: Yes,  Allen Hall: exactly. I don’t necessarily want to increase power. I don’t wanna put more load in my blade, but people do that. I’ve seen that happen and man, they regret it.  Nicholas Gaudern: Yeah, regret it. There’s, there’s some pretty wild claims out there as well about observations can and can’t do. And uh, like with lots of things, it’s important to just do the simulations, speak to some experts and, um. Yeah, maybe take the, the less exciting path, you know, sometimes,  Allen Hall: well, no. Yeah. Well, less exciting path where I don’t have a broken blade.  Nicholas Gaudern: Yeah, exactly.  Allen Hall: Yeah. That’s a lot less exciting. It’s, it’s definitely more profitable. Now, the Dragon Scale Vortex generator has been [00:09:00] around about a year or so.  Nicholas Gaudern: Yep, yep.  Allen Hall: And the thing about these devices, and they’re so unique, interesting to think about because you typically think of a vortex generator as this being this little bit of a fence. Where you are tripping the air and making it fall back down onto the blade.  Nicholas Gaudern: Yep.  Allen Hall: A really, it works.  Nicholas Gaudern: It works.  Allen Hall: But it’s it’s  Nicholas Gaudern: been around a long time.  Allen Hall: Yeah. Yeah. It, it does, it does do this thing. And they, they were, they came outta the aviation business. We use ’em on airplanes to keep air flow over the control surfaces so we can continue to fly even in close to stall conditions. All that makes sense. And airplanes are not a wind turbine.  Nicholas Gaudern: Yes.  Allen Hall: So there’s different things happening there. So although they work great on on aircraft, they’re not necessarily the most efficient thing for a wind turbine where you’re trying to generate power and revenue from the rotation of the blades. Nicholas Gaudern: Exactly.  Allen Hall: So this is a completely different way of thinking about getting the airflow back onto the blade where it produces [00:10:00] revenue.  Nicholas Gaudern: And what’s really nice is to actually see this together with silent edge, because historically, and maybe not even historically. Serrations VGs, they’re triangles. They work, they do a job. But that doesn’t mean you can’t do it in a different way. In a better way.  Allen Hall: Right.  Nicholas Gaudern: And that’s the same principles from applying with Silence Edge and Dragon Scale. We want to work the flow in the most efficient way possible.  Allen Hall: Right. You’re trying to get to an  outcome.  Nicholas Gaudern: Yeah, exactly.  Allen Hall: Efficiently.  Nicholas Gaudern: We want to, we want to target very specific things on the blade, and that’s where you can see there’s a few different styles of Dragon Scale that we have on the table here. We have some that are two fins. We have some that are three fins. We have different sizes, and this is because they’re tailored to different parts of the blade. So these three Fin Dragon scales, their focus is ultimate lift. We are creating a really powerful vortex through this combination of three air foils, if you imagine, um, the inside of a Turbo fan. You have these cascading air force. [00:11:00] You look at the leading edge slacks on an aircraft. You look at the front wing of a Formula one car. It’s that kind of concept.  Allen Hall: It’s like that,  Nicholas Gaudern: and it’s these air force that are cooperating with each other.  Allen Hall: Right.  Nicholas Gaudern: To end up with a more beneficial result. ‘ Allen Hall: cause an air force by itself does a function, but when you combine airflows together in the right way  Nicholas Gaudern: Exactly. Allen Hall: You can really control airflow efficiently, less losses. More of what you want out the backside. Yeah, exactly. It’s, it’s the backside you’re trying to work on, on a VG or, or dragon scales. You’re trying to create this flow which gets the airflow back onto the blade to create power. We,  Nicholas Gaudern: we want as much attached flow as possible and down exactly down in the roots of a blade. We have to have really thick aerofoils, you know, blades about round. They’re basically cylinders.  Allen Hall: Yeah.  Nicholas Gaudern: And that, that’s essential, right? We have to have the blade take a lot of load into the root aerodynamically. They’re horrible.  Allen Hall: Yeah.  Nicholas Gaudern: So this is where these, uh, these powerful Dragon Scale VGs come into play because what they do is they’re [00:12:00] reenergizing the flow over the aerofoils, and they’re ensuring that that flow remains attached for much, much longer than if those bgs weren’t there. So down in the root, you’ll get significant boosts to the lift that those sections can generate. And what’s more lift? It goes to more torque, it goes to more power, goes to more a EP. So these dragon scale VGs in the root are there to boost, lift, and boost EP out on the tip of the blade. Things are actually a little bit different because it’s way different. You shouldn’t really have stall there to begin with if your blade’s been designed well.  Allen Hall: But if you have leading edge erosion exactly. Or some other things that are happening, you can have real aerodynamic problems.  Nicholas Gaudern: So yeah, as soon as you have erosion, uh, maybe your stall margin is not as big as you thought it was. You’re starting to get some significant losses of lift Yes out towards the tip of the blade. So that’s where these, uh, TwoFin uh, variants come in. So it’s still a dragon scale vg, it’s still the same concept of these cascading error foils. Yeah, but these are [00:13:00] designed for basically ultimate lift to drag ratio. Mm-hmm. So we don’t really want more maximum lift outta the tip. We kind of have enough, but what we do want is to keep stable attached flow and we want to do it for the less, uh, least drag penalty possible. So basically we want to get rid of as much parasitic drag as we can. These two fin dragon scales, we are seeing 25 plus percent improvements in lift to drag ratio. Compared to a standard triangle vg. I mean that’s huge.  Allen Hall: That that is really  Nicholas Gaudern: huge.  Allen Hall: That’s huge, right? Because people have seen these, uh, triangular VGs in a lot of places. And one thing I’m noticing more recently is that those VGs, because they’re so draggy, they tend to flutter and they tend to break in just off. Nicholas Gaudern: Interesting.  Allen Hall: So you’re having this failure mode because this thing is just blocking the air, getting the air to trip.  Nicholas Gaudern: Yeah.  Allen Hall: It’s not efficient. It does have its downsides ’cause it is. D definitely drag. Just face it, it’s it, is it a draggy [00:14:00] 1940s technology? That’s what it is. Where with the dragon scales, now we’re doing things a lot more efficiently and thinking about how do I get the airflow that the blade designer originally wanted? Nicholas Gaudern: Yes,  Allen Hall: because the blade designer, they’re really intelligent people. They’re, they’re sitting designing blades. But the reality is what you design is on an ideal airflow, and what you have out in service are totally different things. As, as it turns out, the shape of the airflow is not what you think it is because it comes out of the tool and there’s a lot of touching with by humans that are grinding on the leading edges and doing the things that have to be done to manufacture it. So you don’t really have an ideal blade when it comes out of the  Nicholas Gaudern: No. You  Allen Hall: never do factory. No, you never do.  Nicholas Gaudern: And it’s not polished either.  Allen Hall: It’s not polished. Right. So  Nicholas Gaudern: when you go to the wind tunnel, you have a perfect profile. Yes. And it’s polished. And it works basically. It  Allen Hall: works great. It  Nicholas Gaudern: works great.  Allen Hall: The theoretical and the actual match. Yeah. In reality they do. I think a lot of operators are not [00:15:00] connected with that reality of, Hey, that Blade should be producing this amount of revenue for me, and it’s not. And you hear that discussion all the time, particularly in the us. It should be producing this amount of power. I’m doing all the calculations. We are not producing that power. Why? The blade length’s saying, but the power’s not coming out of it. Well take a look at your leading edge, take a look at your yard full of shape and realize you’re going to have to do something like dragon scales to get that E energy. Exactly. Revenue back.  Nicholas Gaudern: You need to do a full aerodynamic health check. Basically you do. And see what are all the possibilities to improve my blade performance. And some of it is down to the fundamental shape of the blade,  Allen Hall: right?  Nicholas Gaudern: But some of it is down to blade condition. Yes. Blade Blade manufacturing quality.  Allen Hall: Yes.  Nicholas Gaudern: Uh, what kind of paint did they put on it? What day of the week was it made? And all these things can be compensated for by VGs and you’ll get more revenue out at the end.  Allen Hall: You say? ’cause what happens? The, the, the scenario which is hard to visualize unless [00:16:00] you’re an A and emesis, is that there comes on the suction side, and it should be, in a ideal sense, rolling all the way to the back edge of the blade and coming off. What happens is though, is that. When you get leading edge erosion is that the air flow actually separates. Yeah.  Nicholas Gaudern: It  Allen Hall: doesn’t  Nicholas Gaudern: always make it, yeah.  Allen Hall: Doesn’t make it to the back edge. Yeah. And so you can see that, especially if, if there’s dirt in the air, you can look on dirty blades, you can see where that separation line is, and a lot of operators have sky specs, images or Zeit view images, and then go back and look at the blades. It takes two minutes to go. I have  Nicholas Gaudern: particularly down in the root, you’ll see it.  Allen Hall: Oh, in the root all the time. You, you  Nicholas Gaudern: see it really clearly that that separation line  Allen Hall: all the time, you really see that separation line. I’m seeing it more and more up towards the tip. Interesting. That’s where the lightning protection, yeah. Systems sit.  Nicholas Gaudern: Yeah.  Allen Hall: I see a lot of airflow that is not front to back on the suc. Well, you  Nicholas Gaudern: have a lot of three dimensional flow out there.  Allen Hall: You do towards the tip you do. And you realize how much power you’re losing there. And I think operators are just throwing away money.  Nicholas Gaudern: Yeah, exactly.  Allen Hall: So you could [00:17:00] put dragon skills on it very efficiently, very quickly. Get that revenue back into your system and it’s gonna stay. So even if leading edge erosion happens, the dragon scales are gonna compensate for it. It’s gonna get the airflow back where it should be.  Nicholas Gaudern: Exactly. And the nice thing about this is, you know, we are building on well over a decade of upgrading turbines with aerodynamic components. Oh yes. So this technology stands on the foundations of all of that work. In terms of the materials, the work instructions. Um, the fatigue calculate, you know, everything  Allen Hall: Yes.  Nicholas Gaudern: Is built on thousands of installations that we’ve done. Yes. So, although it’s a new technology aerodynamically, it’s not really new in lots of sensors. Allen Hall: Well, I look at it this way. If you turn on Formula One today and look at what the new generation of cars running around as you look at the, that front. Yes. Uh. Fin. Yeah. What do I call it? Air foil shape in the front. It’s super complicated.  Nicholas Gaudern: The sculpting of the [00:18:00] surfaces is really impressive,  Allen Hall: right? There’s a lot of thought going into those surfaces versus you turn on a Formula One race or go on YouTube and look at a Formula One race from the 1980s. Yeah, it’s basically a piece.  Nicholas Gaudern: Yeah.  Allen Hall: To provide down downforce. That’s it. The aerodynamics wasn’t really there, so we come a long way and a lot of that technology that happens in Formula One that happens in aviation eventually rolls down into. Yeah. Wind.  Nicholas Gaudern: Exactly  Allen Hall: right. So we, we, although we are not designing Formula One style blaze today, we’re taking that same knowledge and information and we’re applying that back in. Nicholas Gaudern: Yeah. We’re  Allen Hall: secondarily we,  Nicholas Gaudern: which is a right thing to do. We’re taking, taking inspiration from all these different aerodynamic fields and, you know, picking the best  Allen Hall: Yes.  Nicholas Gaudern: From what’s available and just allowing ourselves to be a little bit more creative.  Allen Hall: Yes.  Nicholas Gaudern: And thinking outside the box a bit. There’s so many ways to do this as we’ve been saying. And the import. And the  Allen Hall: data’s there.  Nicholas Gaudern: The data’s there. Exactly.  Allen Hall: The data’s there because you’ve been at the DTU Yep. Uh, wind Tunnel, which also has the acoustic piece to it. Yeah. So you have measured data from a reliable source. [00:19:00] You have field data, and you know, you put all these together, you’re gonna get that improvement back. You’re gonna get your invest back, you’ll be more profitable.  Nicholas Gaudern: So Dragon Scale, focus on the AP. And that a EP will, uh, vary depending on the turbine.  Allen Hall: Sure.  Nicholas Gaudern: But we’ll assess the turbine and, and decide the best configuration, and then say silent edge. That’s the focus on the noise reduction. And we’re seeing up to five decibels OASP on the field. It’s, which  Allen Hall: is crazy.  Nicholas Gaudern: It’s even more That’s really good that we were hoping for, you know?  Allen Hall: Yeah.  Nicholas Gaudern: So we, we know this is gonna be a, a great product.  Allen Hall: It looks very interesting.  Nicholas Gaudern: It does.  Allen Hall: It does it. It looks complicated and you think air airflow is complicated. It’s a compressible fluid. It’s not easy to, to just assume it’s gonna do what you think it is. Yeah. You need to get into the tunnel. You need to replicate, you need to do all that work, which is expensive in time consuming. That’s why you go to someone like Power. Curver knows what they’re doing in the wind tunnel, knows how to measure those things and know when they’re getting nonsense. Out of their computer. I  Nicholas Gaudern: mean, you, you’ll pay thousands and thousands of [00:20:00] Euros dollars a day to run a wind tunnel.  Allen Hall: You will.  Nicholas Gaudern: You’ve gotta Absolutely. You’ve gotta turn up with your plan in hand, that’s for sure.  Allen Hall: Oh, oh yeah, yeah, yeah. And I think there’s a lot of assumptions because it, aerodynamics is hard. You know, you watch these blade spin around, you don’t realize how complicated these devices are. They are complicated. Those air force shapes we are running today have been through a lot of history, a lot of history to get to where we are now. Now we’re just gonna take him into the next generation. This, we’re bringing ’em into the two thousands. In sort of a  Nicholas Gaudern: sense, what I’m hoping to see is, you know, with the OEMs, some OEMs do it already, but it’s important to think about these components when you’re designing new blades as well, you should because then that will allow you a much bigger design space to work in. And  Allen Hall: a lot less customer complaints.  Nicholas Gaudern: Yes.  Allen Hall: Where’s my power?  Nicholas Gaudern: Exactly. You know, these products, particularly the VGs, are really important tools for PowerCurve robustness. And some OEMs have known this for a long, long time.  Allen Hall: Yep.  Nicholas Gaudern: And you’ll see VGs on most of their blades. Mm-hmm. Others not so much. And that’s a design choice. It’s a design philosophy. Um, and I think it may not [00:21:00] be the right one, you know?  Allen Hall: Well, I think the operators are asking to get the most out of their turbines. Yeah. Why shouldn’t they? They should be asking for that.  Nicholas Gaudern: I think for a, for a long time, and it’s not just in wind devices, like these have been considered, you know, band-aids fixes when you’ve, you’ve messed something up. But I feel that’s a really negative way to think about products like this. They’re doing something that the kind of raw air fall shape on its own cannot achieve. Sure. Oh no. Right. You know, you might be able to mold some interesting stuff. Uh, as part of the blade, it’s very difficult to, to recreate the kind of aerodynamic effects that these products, uh, have. Allen Hall: Right.  Nicholas Gaudern: So they shouldn’t be considered bandaids or fixes. No. They should be considered opportunities. And ways that you can maximize performance and unlock areas of the design space that previously weren’t accessible to.  Allen Hall: Sure. Every possible component that deals with fluid air is moving this way.  Nicholas Gaudern: Yes.  Allen Hall: Jet engines, you look at jet engine, how much more is going into those jet engines today in terms of this kind of [00:22:00] technology? Yeah. All the race colors, doesn’t matter what class, where it is, is all looking at this anything to do with aircraft, it’s all over this.  Nicholas Gaudern: Yeah,  Allen Hall: exactly. Or, or doing this today. It’s just wind that’s behind  Nicholas Gaudern: wind. Wind is  Allen Hall: significantly  Nicholas Gaudern: behind. No,  Allen Hall: it’s not magic. It’s proven technology. It’s  Nicholas Gaudern: just good engineering. Allen Hall: Well, it’s good engineering and if you call PowerCurve, they’re gonna help you under to to, to understand what you have today and what you could have tomorrow.  Nicholas Gaudern: Yes.  Allen Hall: And how this, these devices will improve your revenue stream.  Nicholas Gaudern: Exactly. You know, we will look at your blades, we’ll give you some good advice and maybe that advice will be that. You know, a certain product isn’t right for your blade. Right. That’s fine.  Allen Hall: That’s an answer.  Nicholas Gaudern: That’s an answer.  Allen Hall: Yeah, it is.  Nicholas Gaudern: But let’s, let’s look at the blade. Let’s see what’s possible, and let’s just have a, have a proper conversation about it over some real data, some real  Allen Hall: facts. Right. I think that’s the key, and a lot of operators are afraid to talk about aerodynamics is it’s, it’s a difficult area to, to start the conversation on, right? Yeah. But I think at the end of the day, when I work with PowerCurve, and I’ve worked with you guys for a [00:23:00] number of years, the answers I get back are intelligent and they’re not. Super complicated. This is what you’re gonna see. This is the improvement. And then we can, this is how we’re going to show you can get that improvement. It’s not magic,  Nicholas Gaudern: no  Allen Hall: power crews backing up with data, which I think is the key, right? Because you’re the, you do hear a lot of noise in this industry about magical products that’ll do all these things. Particularly aerodynamic ones. Yes. PowerCurves, the ones really bringing the data.  Nicholas Gaudern: Yeah. And we have, we have the track record now. We have like we do 17, 1800 turbines. Should be over 2000 very soon with our products on. Yeah. So we have a lot, we have a lot of data to draw on to know that we’re doing a good thing.  Allen Hall: Well, and speaking of that, because one of the questions that always pops up is, well, we have put these new VGs or trailing edges on, are they gonna stay on? How durable are they?  Nicholas Gaudern: Yeah. And that’s a, that’s a really important question to ask was it doesn’t matter how fancy aerodynamic product is, if it falls off the blade.  Allen Hall: Right.  Nicholas Gaudern: So, you know, we’ve spent a lot of, uh, time and effort looking at how we should be fixing these products on. [00:24:00] So we use a, uh, a wet adhesive. We specify a plexus adhesive to put our products in place. Really good adhesive. It’s a great adhesive and it means that they are not going anywhere. Basically. It’s a very, uh, forgiving adhesive. Uh, and it’s a very high spec. So we, we don’t use, uh, sided tape. We might have some of our products for some initial tack to help, you know, get the clear, the clear outta the line exactly. But in terms of the bond itself, that is with a, a proper structural adhesive. So one thing that we are really proud of is that we haven’t got any, uh, reported failures of our panels over all the installations we’ve made. And that’s a combination of materials, but also geometry, work, instructions, adhesive. It’s, it’s the full package. So it’s something that, um, yes, say we’re very proud of. And I think it’s, it’s a big part of what we do at PowerCurve, making sure the product is the right shape. Sure. But also making sure it stays on the blade.  Allen Hall: Well, you see it [00:25:00] from OEMs who have all kinds of aerodynamic treatments on there, and they’ll double set a tape to the blade, and then those parts are on the ground. Nicholas Gaudern: Yeah. And double-sided tape. You can get some really nice spec tape. Sure.  Allen Hall: You,  Nicholas Gaudern: yeah. But it’s not  a  Allen Hall: 20 year device.  Nicholas Gaudern: No. And the installation tolerance required on surface prep is really, really high. So it’s possible. It’s just harder. I think it’s riskier,  Allen Hall: it’s risky.  Nicholas Gaudern: So, you know, I think for us, the adhesive is, is the way to go. And, and it’s been proven out by the, by the track record.  Allen Hall: And some of the things we’ve seen over in Australia is when trailing ulcerations have come off, it’s been a safety concern. So now you got  Nicholas Gaudern: absolutely  Allen Hall: government officials involved in safety because parts are coming up. Turbine.  Nicholas Gaudern: Yeah.  Allen Hall: You  Nicholas Gaudern: can’t have these components flying, flying through the air. That’s, that’s not safe.  Allen Hall: That’s because PowerCurve has done the homework.  Nicholas Gaudern: Yes.  Allen Hall: And has the track record. That’s why you wanna choose PowerCurve. So how do people get a hold of PowerCurve? How do they get a hold of you, Nicholas, to start the process?  Nicholas Gaudern: So, um, you’re welcome to reach out to us in lots of different ways. We’re on LinkedIn. Uh, we have our website, [00:26:00] PowerCurve, dk, um, so yeah, LinkedIn websites. There’ll probably some links on this podcast as well to get in touch. But, um, yeah, whatever way works best for you.  Allen Hall: Yeah, it’s gonna be a busy season. So if you’re interested in doing anything with PowerCurve this year, you need to get on the website, get ahold of Nicholas. And get started, uh, because now’s the time to maximize your revenue.  Nicholas Gaudern: Thanks a lot and great to talk to you,  Allen Hall: Nicholas. Thanks so much for being back on the podcast.

The latest study conducted for the Electoral Commission by the Human Sciences Research Council points to a troubling decline in South Africans’ belief in democracy, with the “demand for democracy” falling from 65% in the early 2000s to just 26% today, driven by growing frustration over corruption, poor service delivery, and a widening gap between political promises and delivery. Concerns are also being raised about declining trust in institutions such as the Electoral Commission of South Africa, alongside alarmingly low voter registration figures and fears of even lower turnout in upcoming elections. Lawson Naidoo, Executive Secretary of the Council for the Advancement of the South African Constitution, speaks to John Maytham about what this means for the future of South Africa’s democratic system and the risks of governments being elected by an ever-smaller share of the population. Presenter John Maytham is an actor and author-turned-talk radio veteran and seasoned journalist. His show serves a round-up of local and international news coupled with the latest in business, sport, traffic and weather. The host’s eclectic interests mean the program often surprises the audience with intriguing book reviews and inspiring interviews profiling artists. A daily highlight is Rapid Fire, just after 5:30pm. CapeTalk fans call in, to stump the presenter with their general knowledge questions. Another firm favourite is the humorous Thursday crossing with award-winning journalist Rebecca Davis, called “Plan B”.

The Uptime Wind Energy Podcast brought to you by Strike Tape, protecting thousands of wind turbines from lightning damage worldwide. Visit strike tape.com. And now your hosts.  Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host, Allen Hall. I’m here with Matthew Stead, Rosemary Barnes and Yolanda Padron. And the UK is really gearing up for offshore wind and they’re making some really smart moves and. One of them is, uh, the change in tariffs. So the British offshore wind manufacturers have been fighting really an uphill battle for a long time and for years. The companies that build turbines and components in the UK have faced import tariffs on the materials needed most, which tends to be steels like steel. Uh, cables, specialized parts from overseas all carried a tariff with it. Well, now the federal government has acted to [00:01:00] remove those tariffs on offshore wind equipment. The move is expected to save UK manufacturers tens of millions of pounds every year. And for an industry trying to cut costs and scale up that kind of relief could make the difference between winning. Losing contracts, and I’m surprised the UK has waited this long and I think other countries have the same problem. Obviously the US is taring the heck out of everything at the minute, but uh, a lot of European countries do put tariffs on the raw materials and the components that are used to make wind turbines. That’s not a smart long term move if you’re trying to deploy. Gigawatts of offshore wind.  Matthew Stead: Well, I, I think, uh, the recent events in the world show that energy security and not importing energy is a wonderful thing. And so this completely aligns with that, um, that objective. So I think that’s why we all agree with you, Alan. Allen Hall: Well do, is there a, a. A threshold here where other countries start to do it [00:02:00] and for whatever reason there’s, there’s tends to be tariffs on energy in all forms of it. Right. And there and on steel in particular, that seems to be a big area of concern. Are we gonna start to see some of those come down just to lower the cost of wind turbines and to deploy the middle of the water? ’cause there is a lot of steel in an offshore wind turbine.  Matthew Stead: It’s been like China. I mean China has, you know, a lot of clean energy, low cost energy and it is to their advantage. So I, I think it’s a entirely logical approach and I would’ve thought it’s, if you’re a good on policy, you would definitely be looking at this. Allen Hall: Is this has been a concern of the UK steel industry, which has been diminishing over the years? Uh, so it’s always been a pain point with the uk. They’ve been trying to stand up their own steel industry and forever they had a big steel industry In the uk you think of all the. The steel that was built from late 18 hundreds all the way up to the 1980s and nineties. Uh, but it does sound like you, you gotta pick and choose your battles here. And maybe the UK has [00:03:00] finally said, okay, the, the steel battle is a separate issue within offshore wind, and maybe we gotta do something different.  Matthew Stead: I mean, I think Australia did the same thing ages ago. I mean, we had a car, car industry and you know, we just didn’t have the scale. So, you know, Australia’s picking its battles and um, yeah, I mean, you can’t be good at everything, so you know why not. Uh, get the, the lower cost energy and um, deal with it that way.  Rosemary Barnes: Australia has actually just announced, you know how Australia’s got the policy to support clean energy technology manufacturing in Australia. And they started with, um, solar panels and then they’ve also got something related to battery cells. Well, they just announced wind turbine tower manufacturing, um, which is very simple. The reason why Australia doesn’t have, um, wind turbine tower manufacturing anymore. Is just because we can’t compete on price with Asia, um, in general and China specifically. It’s interesting now to be like, okay, let’s support Australian [00:04:00]manufacturing of wind turbine towers when like there’s no technological barrier. It’s pure cost, cost issues. I would really love to see the Australian government supporting some of the new manufacturing methods and you know, like we’ve seen that Fortescue has invested in. Um, in Ena Lift, the Spanish, Spanish company, um, ESCU has, has bought their tower manufacturing. Um, it’s, it’s like modular, advanced thing that’s gonna work well for remote areas. Otherwise it’s just like, pay a bunch of money so that we can make towers more expensively, but we can sell them at a competitive rate with the Chinese. And I don’t know, to me that’s not very strategic. I always prefer we support the next, the next thing.  Allen Hall: Whatever happened to spiral welding and making towers on site. I think that died about a year or two ago because they were trying it here in the United States and about building ’em at the wind farm. But it sounded like just setting it up to [00:05:00] build the spiral mechanism, the, the cold, uh, forming plus all the welding on top of it. It got to be so expensive to install on site that it was just easier to, to build a central location, which I think they were going for. I’m not even sure that in today’s world, because of the advanced technology in the existing way of manufacturing is so good and inexpensive that it makes any sense to try anything else. It just seems like it’s, there’s just stamping out parts right now.  Rosemary Barnes: Oh, no. I mean, we definitely need new, new methods because we’re really constrained on how tall towers can get if you just wanna make a steel cylinder and ship it out in, you know, whole pieces, like whole cross sections and. Um, put them together vertically. That’s you. You know, like we’ve, we’ve gotten about as tall as we’re gonna get for that because if you want to go any taller, you’re gonna have to start massively increasing the thickness of the tower to make it stiffen up. And that just means way more steel to keep material costs reasonable. You need to increase the diameter, um, beyond [00:06:00] what you can transport on the road. Um, but I think that it’s like the, the, the problem is definitely real and well established, but it’s like with many other. Problems. You know when you start thinking, okay, we’ve got a solution to this problem at that time, there aren’t other solutions, so you’re sure that you know you’re gonna win. And so spiral welding was one of the early ones. Oh, we can fix this problem, but. While they’re developing that and trying to get the capabilities where it needs to be, the cost down, you’ve got a dozen other competing ways that you could solve that problem. And they include like, um, some manufacturers, I think Vestus is one. They’re cutting longitudinally. And so instead of, um, shipping out towers in a single cross section, it’ll be like four. And then they’re bolted together on site. Um, and then Concrete Towers is another one. The Naber Lift, um, thing that I mentioned.  Matthew Stead: Wooden towers.  Rosemary Barnes: Yeah, wooden Wooden towers is, uh, another one I’ve covered, uh, [00:07:00] on my YouTube channel. Matthew Stead: They really should make them out of carbon fiber, shouldn’t they?  Rosemary Barnes: Well, I have, it’s not, it’s You’re saying that as a, as a crazy thing. It’s not, it’s not such a crazy thing. And I have, I have, I have looked into it. You wouldn’t do it outta carbon fiber. You’d do it outta glass. Um, there’s a lot of. There’s a lot of benefits to it, and I actually do believe that we might eventually see like 3D printed glass, um, towers. Allen Hall: No.  Rosemary Barnes: Now we’re just getting into our standard. I, I believe the future might look different to the, to the present day, and Alan never thinks that anything’s ever gonna change.  Matthew Stead: I would’ve. 3D uh, printed concrete towers would have some logic.  Rosemary Barnes: There’s been pilots of 3D printed concrete, concrete towers. I’m, I’m pretty sure GE had a, um, a project on that and there might have been somebody else that did, took it a bit further. It’s all possible. It’s also like concrete towers are, are good, but it is local. Like it depends on having the right materials around locally. ’cause you don’t want to have to transport Hess of. Concrete and water to site. Um, [00:08:00] so yeah, anyway, the point is that like, just because you’ve identified a real problem and you’ve got a solution to it, if you are gonna take five or 10 years to develop your technology and get it to the right price point, you are not gonna be the only, the only solution anymore. So people often like massively overestimate how valuable their idea is. Um, and by the time that it’s ready, it’s not the best solution anymore. So I think like the lesson from that is to just. You need to just move really, really fast and keep your peripheral vision available to see what other technologies are developing in tandem and know when, when to pull the pin. If you are no longer, you no longer have a path to be the best solution, then. Stop. Even if you’ve got 90% of a solution, don’t bother with the last 10%. If you’re never gonna sell it, you know it’s a waste go. Um, let, let all your smart people work on something else. Allen Hall: Delamination and bottom line, failures and blades are [00:09:00]difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production. C-I-C-N-D-T are specialists to detect these critical flaws before they become expensive burdens. Their non-destructive test technology penetrates deep to blade materials to find voids and cracks. Traditional inspections, completely. Miss C-I-C-N-D-T Maps. Every critical defect delivers actionable reports and provides support to get your blades. Back in service, so visit cic ndt.com because catching blade problems early will save you millions. Can we pull the pin? On digital twins. I came across another company that was pushing digital twins in the wind turbine space. And I thought, I thought we got rid of that a year ago. Can we stop doing that?  Rosemary Barnes: I, um, in general, like I think a lot of times you see digital twins and I can’t see the point, but there are some applications where you [00:10:00] definitely can,  Matthew Stead: uh, I can add on the digital twin, so the IEC 61 400 dash 32, the new blade o and m standard has in the, in its current draft, it has a section on digital twins. Um, and um, at the last meeting there was a debate as to whether that should be taken out because actually, um, AI, ml, um, all these, um, approaches will just overrun the concept of the traditional digital twin. So, um, I was voting for it to be removed, um, but. Other people didn’t. And so it’s still in the current draft. Yolanda Padron: I am a little bit tired around digital twins at the idea of, like, I’ve seen the title slapped around a lot of things that just aren’t digital twins. And I think that gets even more confusing to a lot of people who are just new to the space or new to the idea that then they, they, they hear digital twin, they have like an idea about it or like, oh, it’s really great, and then they pursue something that just [00:11:00] really isn’t, it’s just a. A monitoring system that they wanted to name something else.  Allen Hall: Yes, that’s it.  Rosemary Barnes: I’ve seen it used well in manufacturing, which is not usually what people are selling it as, but you know, if you have a new composite part, for example, and like a wind turbine blade is a really good example, you design it. And then you can only test it to a certain extent. Um, and you never know exactly what you’ve made, right? And so it’s really hard to kind of relate, like to validate your design tools when not every blade is the same. You know, it’s aiming to be the same. The design is the same every time, but you’re gonna get different results every time you test it. But with some advanced, uh, manufacturing, like my favorite thing to argue with Alan about 3D printing, um, fiber reinforced composites. You can really precisely know exactly what your part looks like all through the structure. You know where every void is. Um, you know where every fiber is and then so you know that exact part. Then you can test that exact part, and you do that with, you know, a dozen of them and you can really [00:12:00] build up a model of what kinds of defects are really, um, you know, doing what to the performance output. And then that can help you to get your quality, um, acceptance to really, like you, you can do the things that matter instead of guessing, oh, okay, yeah, we know that we want this much. Bond line, you can actually know, okay, well like where does that matter? Where doesn’t it? What’s the actual threshold? However, it’s very expensive to do that, and I don’t know that it would make sense for wind turbine blades economically, maybe. Maybe it will one day. I mean, if we can get the quality data that we need, there are big pro quality problems that need to be solved with blades so. I think it’s something to not totally rule out anyway. Matthew Stead: That’s quality control. That’s not a digital twin.  Rosemary Barnes: No, but it is. You have the di you have the make up a digital twin of the, of the part that you’ve made, and then you test it and then you can, um, digitally test the [00:13:00] part that you, the model that you have. So it is a digital twin. Um, it’s just used in a very different way to what digital twins are usually sold as. It’s not at the right level yet for a hundred meter long. Composite wind turbine blade. Um, and also because you would need to destructively test, you know, a, a whole bunch of blades which no one can afford to, to do that.  Yolanda Padron: What if we were to take all the money from like FSAs and stuff that they have to spend, like the OEMs actually have to spend from all of the manufacturing defects from, oh, I tweaked this on this blade type in this. Factory and set it to print and then I tweaked it over here and then I set it to print for like hundreds and hundreds of blades. Um, you know, all of that money spent accumulates too, if we really wanna look at the business case. But eventually, I think maybe it’d be great if it were to work out. I am also.[00:14:00] Hoping  Rosemary Barnes: I, I think it would be a really interesting project to work, and I bet I could. I, I bet that, you know, a good project manager could get, get a positive business case out of it. At the end. One of the problems is that like service, the service department bucket of money is not at all related to the manufacturing bucket of money. Um, so, or the, yeah, the engineering back of the money that, that, that would be a really big problem and make it harder to find a positive business case. But I still think that it’s, um. Yeah, it, there’s a lot of potential there. It would be really interesting project to work on.  Matthew Stead: In terms of the operational phase, I, I think, um, like I said before, the A IML tools. A way more powerful with anomaly detection rather than building a, a fancy digital model, which is not accurate. Um, actually you’re better off looking at the deviations and then the anomalies from what you expect. And I, and there are quite a few people that are doing that, and I, I personally think that’s a way more effective method during the operations and maintenance phase. Rosemary Barnes: But I think that that [00:15:00] would be related. It would be a way to improve what you’re doing there because you said, yeah, digital twin, that’s not. Accurate. So you would need to be accurate. That would be the project to figure out like how you can get accuracy in the right places that you need it. You wouldn’t be able to afford to have accuracy over the entire blade ’cause it’s just way too much data. And then, um, it would help you to figure out like what anoma, what anomalies do we need to look for that are the, the critical ones. I, I think that they would, they would work in partnership. Um, not as two separate things. Can I just plug, because I’m gonna go to China in April and can I just plug that if anyone has any projects, I’ll be there anyway. And um, yeah, so I am sharing the cost of the trip between a few different collaborations and there will be a chance. To, to get me out there to see some manufacturing, et cetera. Would be really excited to go visit some Chinese [00:16:00] manufacturing, some Chinese development. Got a few, few tentative irons in fires at the moment, but would love to have Chinese companies reach out to me and see if we can arrange a collaboration  Allen Hall: as wind energy professionals. Staying informed is crucial, and let’s face it difficult. That’s why the Uptime podcast recommends PES Wind Magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future. Whether you’re an industry veteran or new to wind, PES Wind has the high quality content you need. Don’t miss out. Visit PS wind.com today. It has been a turbulent chapter in offshore wind in America. No doubt about that vineyard wind. The first large scale offshore wind project in the US has faced a crazy difficult road after months of uncertainty, partial construction, and a federally ordered pause. The [00:17:00] project has reached a telling milestone the first. And final shipment of the last blade has departed the port of New Bedford, Massachusetts. And, uh, the blades were just sitting on port for a little while. Uh, Keyside. So this is the last blades or set of blades that’s going out to a turbine. This should sort of wrap it up. I, although I do think there are a couple of blades that may still need some modification updates, something of the sort. But in terms of getting termites out in the water. This should be it. And remember a few months ago, GE and uh, a number of others, vineyard was saying that they’re trying to be done in March. So they’re going to come really close to doing that. And that I know they’re trying to get power all turned on for the site. Because once that happens, it’s really hard for the, uh, the federal government to put any stops on them. I, I guess the question is now, is there any future for offshore wind for [00:18:00]ge now that this is complete and, and it’s kind of off the books, which is what they’ve been trying to do for the last roughly two years, is get it off the books. Matthew Stead: Um, as a positive, I mean. You know, every industry goes through challenges and improve. So I mean, despite all the turmoil, you know, there has to be some good come from it, even though it is been a painful, horrible process. You know, surely there’s some good come from it in terms of improved quality in the future, improved processes, so,  Allen Hall: well, I, I guess that’s the question is are they taking some of these lessons learned and applying them, or are they taking the lessons learned and saying we’re not gonna do that again in, in terms of going down the pathway for offshore wind. Matthew Stead: Well, I think if, uh, if they don’t apply the lessons, that’s sort of, it shows a massive failure of an organization.  Allen Hall: Yeah. It may, I guess it’s a question if it’s a technical failure or a financial failure. Maybe it’s both at the minute until they get everything up and running. But I think the financial side has been. Driving a number of the, of the decisions because the [00:19:00] technical side hasn’t gone all that well.  Matthew Stead: Uh, I think, uh, I think the financial side is an art, which I don’t understand.  Allen Hall: Yeah. Yeah. There’s a lot of moving pieces in financing offshore wind. Now, Vestas has won a, a couple of big. Uh, orders from RWB offshore and Vestus has obviously been in, in some offshore, not at the scale as originally as some of the other OEMs. It does look like the future is bright for Vestus offshore. Is that just gonna continue on that? Vestus is going to invest heavily in offshore and basically dominate that market. Or compete against a a Chinese manufacturer. It doesn’t seem like Siemens is gonna win a lot of offshore contracts off. At least today it doesn’t. You don’t see a lot of noise about that. You see mostly Vestas winning these gigawatt orders. It almost seems inevitable they’re gonna win most of them.  Matthew Stead: Um, I don’t, being long way, way away from where these projects are being made, uh, installed. Um, I don’t have the same sort of insights. [00:20:00] Um, but, um, I mean, obviously yeah, vest, MHI, the previous, um, you know, joint venture with MHI, which especially heavy industries. Um, obviously they’ve come from a, a long pedigree of, um, working offshore, so yeah, I mean, why not? And, um, it seems to be a more of a gradual ramp up, um, and a more orderly, systematic ramp up for offshore. So, yeah. Why, why wouldn’t that work?  Allen Hall: Well, we should hop on the. China discussion because, uh, China’s when turbine makers obviously been trying to build turbines in, in Europe at scale for quite a while now. Uh, and Ying Yang is talking about focusing their efforts on. Germany and they have joined the German Offshore Wind Association BWO. And this is not just a membership cards, uh, that they have subscribed to. It is really like, in a lot of people’s opinion, a strategic signal that Ming Yang intends to compete in the European off.[00:21:00] Market, maybe starting with Germany. Ming Yang was trying to get into Scotland originally, and they were talking about a billion and a half pounds being poured into Scotland to develop factories for offshore wind. Maybe that has come, uh, time has passed and Ming Yang is moving on to Germany. That’s what it reads like to me. Or, or they’re gonna hedge their bets and, and look at both places to see if they can get a foot. Print established in either country.  Matthew Stead: I mean, reputation matters. So you really need to build up a, a footprint. And why would you apply a scatter gun approach? So, I mean, you know, just targeting, you know, one region or, um, you know, makes complete sense to me. So, you know, get, get, get some turbines in the water, get them up and running, get them, get the reliability and the, the reputation, and then, and then go from there. I mean, made complete business sense.  Allen Hall: Well, does that mean that, uh, a mean yang is going to have to lose a little bit of money early on to get some turbines in the water just to demonstrate that they [00:22:00] can do it at scale in Europe? Matthew Stead: I might defer to Rosie, but I would’ve thought they don’t need to, you know, cut costs. I think they’re already cost effective. So you would’ve thought they would just go in, um, with their, their normal product offering and still be successful. Uh, but maybe I’m, I’m on the wrong mark there.  Rosemary Barnes: My understanding is, and I, I don’t know heaps. But my understanding is with Chinese when turbines, that there’s a separate version for the Chinese market, and then if they wanna sell it internationally, then they need to make a new version of it that will pass the IEC, um, standards and the kinds of, you know, certification testing that everybody in those markets is used to. So you’re not always getting, or I don’t think you, I think you’re usually not getting the exact same product. So just because the product exists in China doesn’t mean that it is. Um, without risk in new markets.  Allen Hall: Well, I’m, I’m just curious if ING Yang will have to do a complete IEC certification process because they haven’t done it yet. Uh, is that what you’re saying?  Rosemary Barnes: They do [00:23:00] a, actually a redesign so that they can pass the, um. Certification and then they, yes, they do the whole certification process. However, Mingan hasn’t sold no turbines outside of China. So they have, or it’s not like this is a brand new thing for them that they’ll have to have to, you know, figure out as they go. Um, they’ve, they’ve, you know, I, I, if they haven’t done it for these specific turbines that they’re planning to manufacture in that factory, they’ve at least done it for others and know the process. Um, yeah, and I think we all know it’s not that hard to pass a certification test, so it’s not like a huge obstacle for them. But it will add, it will add cost to the, um, to the process and to the product. Probab probably, you know, there are some design changes that will be needed that will increase the cost of the product. So I don’t think that we’re gonna see, um, you know, Chinese turbines from any, any manufacturer outside of China that are as cheap as the prices that you see within China. Matthew Stead: To be fair though, um, there is a strong, um, Chinese involvement in the IAC committees. So, um, [00:24:00] definitely the, the standards are being used. So, you know, the standards are being used in China, and so I, I don’t think it’s a huge stretch from, you know, the, the domestic product versus the international product.

In this deep-dive episode, host Etienne Nichols shifts away from the "inspiring" fluff of entrepreneurship to deliver a gritty, practical masterclass for medical device founders. Drawing from his experience judging at MedTech Innovator and speaking with hundreds of founders, Etienne highlights a sobering reality: success in this industry isn't just about having the best technology. It is about getting the right specialized experts in the room at exactly the right time to avoid the "walls" that sink most startups.The conversation centers on the critical importance of early-stage strategic planning. Etienne argues that the most important first step for any founder isn't building a prototype or filing a patent—it's establishing a regulatory strategy. By understanding the classification and requirements of a device early on, founders can prevent the catastrophic loss of capital and time that occurs when a design doesn't match the eventual clinical or regulatory data requirements.Finally, the episode walks listeners through the transition from design to commercialization. Etienne emphasizes the "valley of death" that occurs after FDA clearance, where many companies fail because they lacked a reimbursement strategy. This episode serves as the essential recording Etienne wishes he had ten years ago, offering a comprehensive blueprint for navigating the complex MedTech ecosystem in 2026.Key Timestamps00:01:17 - The Idea Stage: Why regulatory strategy must come before the prototype.00:03:02 - The "First Three": Essential roles for the early idea phase.00:05:35 - Stage 2: Design and Development—The reality of design controls and ISO standards.00:08:11 - Building your quality system and the necessity of risk management (ISO 14971).00:09:18 - Human Factors: Why the FDA cares about the "layperson" user experience.00:10:33 - The Manufacturing Dilemma: Why Etienne recommends a CMO over in-house production.00:14:28 - Stage 3: Testing and Verification—Managing backlogs and accredited labs.00:17:27 - The Biological Evaluation Plan: Why you need a biocompatibility expert.00:19:02 - The role of the statistician in clinical data and test methods.00:20:07 - Stage 4: Submission and Clearance—The craft of telling your regulatory story.00:22:33 - Reimbursement Strategy: The missing link that saves businesses from the "Valley of Death."00:24:07 - Stage 5: Commercialization—Navigating the post-clearance landscape.Quotes"Your regulatory pathway is going to determine everything. It determines your timeline, your budget, your clinical requirements... it's like eating your vegetables before you're even allowed to look at dessert." - Etienne Nichols"The companies that make it aren't always the ones with the best technology; they're the ones who get the right people in the room at the right time." - Etienne NicholsTakeawaysRegulatory First: Never spend significant capital on prototypes until you have a confirmed regulatory classification and pathway.Document from Day One: Start your design controls and document control early to avoid "recreating history," which is expensive, painful, and often leads to reverse engineering.Leverage CMO Expertise: In 2026, partnering with a Contract Manufacturing Organization (CMO) is often superior to in-house manufacturing due to their specialized knowledge in DFM (Design for Manufacturing) and process validation (IQ/OQ/PQ).Plan for Reimbursement Early: FDA clearance does not guarantee a business. Without a CPT code or a clear insurance coverage path, a device cannot be commercially successful.ReferencesISO 13485:2016: The international standard for medical device quality management systems.ISO 14971: The essential standard for the application of risk management to medical devices.ISO 10993: The standard series for the biological evaluation of medical devices.IEC 60601 & 62304: Standards governing electrical safety and software life cycle processes.Greenlight Guru: Provides QMS (Quality Management System) and EDC (Electronic Data Capture) solutions specifically designed for MedTech.Etienne Nichols' LinkedIn: Connect with Etienne for expert connections and industry insights.MedTech 101 SectionDesign Controls Think of design controls like a rigorous "paper trail" for a recipe. If you were baking a cake for a grocery store, you couldn't just throw ingredients in a bowl. You would need to prove what the ingredients were (Inputs), show that the final cake matches the recipe (Verification), and confirm that people actually enjoy eating it (Validation). In MedTech, this process ensures the device you built is exactly what you intended to build and that it actually helps the patient.510(k) vs. De Novo vs. PMA510(k) (Cleared): Your device is "substantially equivalent" to something already on the market (a predicate).De Novo (Granted): Your device is low-to-moderate risk, but there is no existing predicate.PMA (Approved): For high-risk, Class 3 devices (like a pacemaker). This is the most stringent path and almost always requires clinical trials.SponsorsThis episode is brought to you by Greenlight Guru.
