While we can get pretty far with a very simple approximation of what a fire is in our fire cfd, at some point our simplications are not enough. And there is a plenty of features and phenomena, for which we simply need a better tool to handle - carbon monoxide, soot, extinction, flashover behavior, and what happens when ventilation disappears. At the IAFSS symposium, we sit down with Professor Bart Merci (Ghent University), fresh off delivering the Howard Emmons Invited Plenary Lecture, to talk about what it really takes to model turbulent combustion in real fires without asking practitioners to become full-time combustion scientists.We start with the engineering reality check: you do not get unlimited mesh resolution, unlimited runtime, or the luxury of endless sensitivity studies. As Bart says - "you need to pick your battles". That practical constraint shapes everything, from whether LES is a smart choice to how you treat the “unseen” physics inside a CFD cell. Bart breaks down turbulence in plain terms, explains why the largest eddies dominate entrainment and smoke movement, and shows how mesh decisions can quietly decide whether LES outperforms unsteady RANS in practical smoke control and compartment fire problems.Then we go deep on sub-grid combustion models. We unpack why infinitely fast chemistry can be acceptable in well-ventilated flames yet collapses in under-ventilated conditions, where toxicity, soot, and extinction dominate the risk picture. Bart explains a finite-rate, autoignition-informed approach that uses detailed chemistry offline to tune simplified reactions, then applies flamelet concepts and turbulence measures to predict reaction rates and species production inside each cell, including ignition and extinction behavior without relying on a guessed “critical flame temperature.”We close with what's next: validation in compartments, microgravity as a brutal test of “universality,” and why advanced non-intrusive diagnostics could finally improve near-wall heat transfer and flame-surface interaction. If you care about CFD, FDS modeling limits, fire dynamics, and the future of practical fire safety engineering, you'll want this one. If you would like to read more on the topic, here is Bart's paper that accompanied his brilliant lecture. Figure 3 is what we discuss at the end of the episode.----The Fire Science Show is produced by the Fire Science Media in collaboration with OFR Consultants.

In this episode, our host and Head of Research, Thilan Wickramasinghe, discusses how optimism surrounding a US-Iran peace deal and the reopening of the Straits of Hormuz is easing inflation concerns and supporting risk assets globally. With oil prices falling and central bank pressures easing, he highlights why Singapore markets could be a key beneficiary, supported by strong liquidity, AI-driven growth and resilient domestic fundamentals.We begin with SGX, where Thilan explains why Maybank is raising its target price and maintaining a BUY call. He discusses how safe-haven inflows, market reforms and corporate restructuring activity are driving higher trading volumes, stronger derivatives activity and a structural improvement in market liquidity.Next, our Analyst, Xuan Hao Toh, shares his views on Singapore Investment and Finance following recent meetings with management. He discusses the company's growth outlook, AI integration strategy and why he reiterates a BUY call on the stock. Thilan then turns to the World Cup, examining how Singapore equities have historically performed during tournament years and highlighting 10 stocks that could benefit from increased travel, hospitality, consumer spending and financial activity. He also shares insights from Maybank's proprietary AI model on the tournament favourite.Finally, Head of Client Engagement, Alex Furber, joins the show to discuss the sharp moves in oil and gold prices following developments in the Middle East. He explains how traders can position for volatility and introduces new opportunities available through Maybank's CFD platform.
Cam Darlington is Global Strategy Expert at Mitrade, the Australian-founded CFD trading platform regulated by ASIC in Australia and CySEC in Europe, offering forex, commodities, indices, shares, and crypto from a single account. A Nova Scotia native based in Hong Kong for the past eight years, Cam brings a dual perspective: a traditional finance background working with brokers expanding across Asia, and recent experience as co-founder and COO of easy.fun, a social trading app built on Solana and Hyperliquid. Why you should listen Cam has a name for the phenomenon most people inside traditional brokerages never see from the trenches: the convergence. TradFi and crypto are collapsing into a single market structure, and the pivot point, he argues, is Washington. With the CLARITY Act working through the Senate and President Trump signing the Integrating Financial Technology Innovation into Regulatory Frameworks executive order in May, digital asset brokers are being ushered toward the core plumbing of the US financial system, including direct access to Federal Reserve payment rails. Add growing regulatory comfort with tokenized stocks trading at parity with their underlying assets, and the discount problem that dogged early real-world-asset experiments like Robinhood's tokenized equities starts to disappear. Tokenized RWAs, Cam says, just became viable. The second-order effects are reshaping market infrastructure itself. When a broker like Robinhood can mint tokenized stocks on its own proprietary chain and handle execution and settlement in-house, it stops feeding liquidity to the public exchanges. Cam frames the exchange's recent moves, including its tokenization partnership with Kraken built on the xStocks framework, as a defensive response to exactly this threat. He speaks from experience here: his team at easy.fun integrated the xStocks API and saw firsthand how thin liquidity gets once you trade beyond Nvidia, Apple, and Tesla. Cam says players most at risk are the centralized crypto exchanges, squeezed between newly crypto-enabled traditional brokerages on one side and purpose-built DeFi venues like Hyperliquid on the other. For traders, Cam's message is about survival. The first year determines whether someone becomes a trader or a statistic, and he is scathing about platforms offering 1,000x leverage to beginners, which he likens to handing a brand-new driver a Ferrari and pointing at the motorway. He makes the case for starting on a regulated platform with guardrails, modest leverage, built-in TradingView charting, and daily strategy feeds, which is precisely the gap Mitrade aims to fill as a companion to a traditional brokerage account.

David Hochberg calls Shaun with a call to arms to help a longtime South Side family business who makes apparel supporting CFD, Shrader's Goods, as the City of Chicago has sent them a cease and desist. And Randy Hultgren, Director of the Alliance of Health Care Sharing Ministries, tells Shaun his story of leaving Obamacare for a Health Care Sharing Ministry and how much it has saved his family.See omnystudio.com/listener for privacy information.
Jumping straight to CFD has become the default move in fire safety engineering, but that habit can quietly weaken our work: more inputs, more assumptions, more ways to be wrong, and often no clearer link to the actual design question. We sit down with Craig Hofmeister and Brian Klein to unpack a practical, defensible way to choose the right fire model for the job using the SFPE guideline “Substantiating a Fire Model for a Given Application.”The broad framework of this work is to define the phenomena of interest and questions at hand, then choose the candidate models and evaluate them through set of core qualities, then address the verification and validation of the models, consider uncertainties and user impact, and finally document the whole process.We walk through the framework step by step, starting where good performance-based design always starts: the questions the model must answer. From sprinkler and detector activation to atrium smoke control, pressurization, visibility and tenability, we talk about translating objectives into key physics and required outputs. That sets up a grounded comparison across hand calculations and algebraic correlations, zone models like CFAST, node network tools like CONTAM and Ventus, and field models like FDS built in PyroSim.From there, we get into the part many projects rush past: verification versus validation, how to use published V&V evidence (and when you are outside the validated scope), and how uncertainty and user effects should shape your confidence. We also address real-world constraints like AHJ expectations and contract requirements, plus practical tools like sensitivity studies, bounding analysis, and grid sensitivity checks to keep complexity from turning into false precision.If you want a cleaner way to defend your modeling decisions to reviewers and stakeholders, this conversation gives you a repeatable process you can build into your own practice.----The Fire Science Show is produced by the Fire Science Media in collaboration with OFR Consultants.

Ingmar Jungnickel, an expert aerodynamicist, earned this distinction for his work with US Speedskating, where he developed a revolutionary team pursuit technique known as the 'American Push'. This strategy used advanced simulation and computer modeling to help the team break world records. His career includes: Specialized Bicycles: He led the aerodynamics department, overseeing the development of high-performance bikes like the S-Works Tarmac and Venge. US Speedskating: He serves as the Chair of the Sports Science Commission and is the 2018 US Olympic Committee Sports Science Coach of the Year. Innovation: He is the founder of AiRO, an AI-powered platform that uses computational fluid dynamics (CFD) to provide aerodynamic bike fitting without a wind tunnel. Aerodynamics plays a significant role in cycling performance, often more so than the weight of the bike. Ingmar emphasizes that many athletes mistakenly believe that a lighter bike is the key to speed. However, the real challenge lies in minimizing aerodynamic drag. By focusing on reducing drag, cyclists can improve their efficiency and speed without the need to invest heavily in new equipment. This insight is crucial for all cyclists, particularly those who may not have access to high-end gear or professional training. One of the most exciting developments at AiRO is the introduction of the Digital Airo Twin technology. Ingmar explains that this innovative approach allows for the creation of a 3D model of an athlete based on just a few photos. This model can then be adjusted for various parameters like limb length and body fat percentage, enabling customized aerodynamic assessments. This technology democratizes access to aerodynamic testing, making it feasible for everyday athletes to optimize their performance without the high costs associated with traditional wind tunnel testing. 0:00:03 - Introduction and welcome 0:01:04 - Journey into aerodynamics 0:03:11 - Development of aerodynamic testing technologies. 0:10:58 - Digital twin technology and its applications 0:16:22 – How AiRO is used by athletes and Fitters 0:28:49 - Upcoming developments and industry impact 0:42:57 – Final thoughts LINKS: AiRO at https://www.airo.app/

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.
Warum ist ein einfaches Prallblech noch lange kein guter Aerosolabscheider? In dieser KI-gestützten Podcast-Episode sprechen wir über moderne Luftreinhaltung, die Entwicklung von Abscheidern, die Grenzen einfacher Filterlösungen und die Bedeutung von Strömung, Messtechnik und Oberflächenstruktur. Die Folge ergänzt unser zweites REVEN cci Webinar 2026 und verweist auf die vollständige Video-Aufzeichnung in den Shownotes. Die Grundhaltung dahinter ist klar: Industrielle Luftreinigung bedeutet nicht nur, Luft zu bewegen, sondern Schadstoffe daraus zu entfernen.

Il partage son cheminement, de ses premières curiosités scientifiques à son rôle actuel au cœur de la recherche appliquée, où il travaille sur des sujets variés mêlant spatial, ingénierie système et durabilité. L'épisode aborde notamment la question des débris spatiaux, un enjeu largement invisible, mais aux conséquences très concrètes, qui illustre parfaitement son approche de la recherche : explorer, modéliser et progressivement faire émerger des solutions ancrées dans le réel.Un épisode éclairant, pour découvrir le parcours d'un ingénieur passionné par la science et convaincu que la recherche est avant tout une aventure humaine.
In dieser KI-gestützten Podcast-Episode sprechen wir über ein Thema, das in der Ablufttechnik und Lüftungstechnik immer wichtiger wird und gleichzeitig häufig falsch verstanden wird: CFD, also die numerische Strömungssimulation. Viele Darstellungen von Luftströmungen wirken auf den ersten Blick technisch und plausibel. Pfeile, Strömungsbilder oder Visualisierungen vermitteln schnell den Eindruck, dass klar ist, wie sich Luft verhält. Doch genau hier liegt das Problem: Diese Darstellungen haben mit der realen Strömung oft nur wenig zu tun. In dieser Episode werfen wir einen Blick hinter die Kulissen moderner Strömungssimulation und zeigen, was tatsächlich notwendig ist, um Luftströmungen realistisch zu analysieren und zu verstehen. Sie erfahren unter anderem: • was CFD wirklich bedeutet und wie Strömungssimulation funktioniert • warum einfache Darstellungen mit Pfeilen häufig in die Irre führen • welche Rolle Modellierung und Rechennetze bei der Simulation spielen • warum Luftströmung und das Verhalten von Aerosolen nicht identisch sind • weshalb die zusätzliche Betrachtung von Partikelbahnen entscheidend ist • und wie CFD zu neuen Erkenntnissen in der Produktentwicklung führt Anhand konkreter Praxisbeispiele – unter anderem aus dem CFD-Kompetenzzentrum der SCHAKO Group – wird deutlich, wie groß der Unterschied zwischen theoretischen Annahmen und realen Strömungsverhältnissen sein kann. Diese Episode richtet sich an Planer, Ingenieure, Fachbetriebe und alle, die sich mit Lüftungstechnik, Luftreinhaltung und realen Strömungsprozessen beschäftigen. Weiterführende Inhalte, Fachartikel und Praxisbeispiele finden Sie auf unserer Website unter www.reven.de in der Rubrik „Blog“. Alle relevanten Links haben wir in den Shownotes zu dieser Episode für Sie zusammengestellt.
In this episode of the Laidback Bike Report, we go behind the scenes of one of the most exciting and secretive recent developments in the recumbent world: The Theta Velomobile. For months, a small team of 4 scientists and engineers in Germany worked in total silence, even hiding their Strava data to keep their project a secret from the "nosy folks" on the German Velomobile Forum. They decided to move beyond modifying existing designs like the DFXL to start with a completely clean slate. The result is a 19kg racing machine that didn't just meet expectations—it dominated. In its public debut at Aldenhoven, the Theta shattered the long-standing 4,000m world record and went on to set a new 24-hour relay record with an average speed of 64 km/h. In this interview, one of the designers-Julian Kraft-discusses:-Lightweight Engineering: How the team achieved a race-ready weight of just 19kg. -The "Secret" Strategy: Why they kept the project hidden until the very last moment. -World-Class Testing: The transition from digital CFD simulations to real-world track testing and world record attempts. -Daily Utility vs. Racing: Why the Theta was designed not just for the track, but for day-to-day commuting and travel. Whether you are interested in high-end aerodynamics, lightweight carbon fiber construction, or the thrill of world-record HPV racing, you won't want to miss this deep dive into the Theta Project.00:00:00 Intro00:00:30 What's on Today's Show00:01:13 Panel Introduction00:02:15 Sponsor Introduction00:07:20 Honza Galla with Recumbent News Segment00:13:45 Julian Kraft Interview on the Theta Velomobile01:17:35 Julian responds to questions and comments on the Theta01:34:00 Larry Seidman with the Recumbent Sports Report01:42:20 Sponsor Thanks01:47:25 Announcements01:49:20 Goodbye to panel and crewPlease subscribe to us on YouTube (https://goo.gl/CHOOgX) and Like us on Facebook (https://www.facebook.com/laidbackbikereport/) if you haven't already done so.

Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m here with Yolanda Padron, Rosemary Barnes at Matthews Stead, and we start off. On the Danish trip to Australia, 54 Danish companies traveled to Australia alongside King Frederick II and Queen Mary. Uh, over the past week, most work in the renewable energy and green construction businesses that traveled along several signed agreements during the trip. Denmark sees Australia as a growth market, and Rosemary is tied to royalty here. Loosely that Queen Mary is actually from Tasmania, much like Rosemary. [00:01:00] So there is possibly a line to the throne, the Danish throne for Rosemary. Rosemary Barnes: My dad’s from Tasmania. I, I live in Canberra, but I was, the whole five years I was living in Denmark, I kept waiting for Princess. She was Princess Mary at that point, but Princess Mary to get in touch with her phone number, catch up. You know, Australians have moved to Denmark. Never happened. And now I see that they’ve come to Australia. And do you think that Mary reached out and got in touch with me? No, she didn’t. So I continue, continue to be disappointed in, in Queen Mary. Matthew Stead: Maybe she’s waiting for you, Rosie. Rosemary Barnes: Yeah, she could be waiting for me to reach out. That’s true. Allen Hall: But I clearly, Australia is a growth market. Denmark sees it. I know there’s been a number of Danish companies in Australia over the last two, three years, or con companies from all over the world have been down to Australia, realizing that the growth of renewables is gonna be big because Australia is targeting 82% renewables by 2030. Uh, and right now it’s about 50% renewables, which is [00:02:00] remarkable by the way, that connection to Denmark. Is only going to grow, especially with the relationship with Queen Mary to the area. What are some of the growth areas that Denmark can walk into in Australia right now, Matthew? Matthew Stead: I mean, obviously the proposed offshore wind is a, is a big thing. So, um, once that gets up and running, obviously the Danish technology will come in there. Um, but, but also, you know, through vest have been here forever. Uh, Siemens, gaa, you know, there’s a strong Danish connection there. Um, so. Yeah, I, I think it’s already, already, already really strong. And, um, obviously having the, the queen, the Danish queen, um, yeah. Ties in with all of that. Allen Hall: Is it a reciprocal agreement that Australians can do work in Denmark? Rosemary Barnes: I don’t think, it’s not any sort of like free trade agreement, is it? It’s just some individual, I dunno how much we’ve, we’ve got to [00:03:00]teach Denmark, although there are some good Australian technologies, like maybe not building wind turbines themselves, but there are some good technologies like here, logic’s Ping, uh, Australian developed the ping part of it anyway. And then also, you know, I think some, some future manufacturing methods, uh, doing some exciting things here in Australia. Also, it’s not that hard to move to Denmark if you, um, like when I moved there, all I needed to get a Visa was a, a job offer. That was a certain, I, I don’t think it, I don’t, I don’t remember exactly if it was the type of job or if it was the salary, but you know, like you’re not gonna get a job offer. Like working part-time at a bar isn’t gonna be enough to get you a, a working visa in Denmark. But certainly. Any engineers, um, you can, if you get a good engineering position offered to you in Denmark, it’s not hard for the company to make that happen. So I don’t know that we need, we don’t, we don’t really need it made that much easier for us [00:04:00] to get over there. Allen Hall: Is it difficult to get a work permit in Australia if you’re from Denmark? Rosemary Barnes: Yes and no. It’s not like I would so love to be hiring my XLM colleagues to come. I know that I’d moved to Australia too. Some of them, it’s, it’s not super duper easy. Um. It’s not impossible. And uh, if people are young enough, it’s a bit easier. But, um, it’s, it’s definitely possible, but it’s not, it’s not straightforward. It’s quite expensive and lengthy process. Matthew Stead: You know, if they can fund a fund, um, themselves with a couple of million dollars, that’ll make it easier. Rosemary Barnes: It’s definitely beyond my capabilities as a small company of like four, four people to be able to, um, sponsor someone. But I have had, um, actually. Most, maybe. Yeah. Every single employee actually that I’ve had has been, has non, not an Australian citizen, but they’ve all had visas for other reasons. You know, either because they came over with a partner who, um, was an unskilled working visa or because they did a master’s [00:05:00] here and then got a, um, a, yeah, after that got permanent residency through the, you know, the, there’s a pretty established pathway after studying to be able to get permanent residency. Definitely appreciate that there is so much, um, international talent that’s willing to come to Australia, but just yeah, unfortunately any, any random skilled person, you, it’s not, it’s not easy for a small company to bring them over. Matthew Stead: Rosie, would you recommend Australians to go to Denmark to learn about the wind industry and then, and come back again like you did? Rosemary Barnes: I recommend that they do that in 2016 when I did it. Um, so everyone who’s got a time machine. Hop, hop in, hop in your time machine and go, go do that. I mean, it’s, uh, I was looking back through, um, photos, uh, of my time there recently and was just, uh, like thinking about how much work I did and the amount of time that I spent like in, in production is like I got in my. Four years that I was working for lm, I had at least 10 years worth of experience. And I mean there were [00:06:00] some long, long weeks, but I’m not sure that Denmark’s the right place now because for LM there’s nearly no engineering left in Denmark and certainly not doing the cool, new, exciting technologies that they were while I was there. So that’s not the go Vestas is still doing a fair bit. But you know, we talked recently about the Vestas CO wanting to, wanting to move somewhere with more favorable. Taxation of CEOs salaries. So, you know, maybe that’s not continuing. So I definitely recommend moving to another part of the world early on in your career while you’ve still got enough energy to, to, to like really, really hard work. Um, but I dunno that Denmark is, is the right place anymore. There’s not that much manufacturing left Now. Based on your experience in both Denmark and Australia, how likely do you think that any of these companies that are coming in. To Australia will do any r and d with data from Australia for all of these wind technologies that they’re bringing. Rosemary Barnes: I, I think that there’s some interest in that. I haven’t heard [00:07:00] Danish companies specifically. I have heard a few little inklings of US companies who are interested and I think that that makes a lot of sense because the US was a much more attractive environment for wind energy technologies until a couple of years ago. So there’s a lot of companies that got partway and now are frustrated and I think that Australia seems quite attractive to them. So that’s where I’ve heard people interested, maybe British as well. Um, the Denmark Danish companies would do well. Like any company, um, that’s trying to develop a technology related to wind energy would, um, do really well to come try and develop in Australia because, you know, like, um, we’re so short staffed or like for expert staff. Things are really spread out. Costs are very high. Um, things wear out faster. Like we just have more operational problems here. So, you know, when you’re putting a business case together, you need to, um, you know, an environment where you are. The alternative of just doing everything manually is [00:08:00]far more expensive here, and it takes far longer so you can get a much more positive business case, um, in Australia, like earlier than you could somewhere else. So I think that that makes it really. Really like perfect place to develop technologies. Um, yeah, but I don’t think everybody realizes that yet. But I do see some, some people starting to, Matthew Stead: and I’m adding to what you’re saying, Rosie, when I first started in wind, um, back in 2012, um, I got great reception from Denmark. Actually, I probably got the most. Positive responses to my outreach from Denmark. So, um, I, at that point in time, you know, it is a little bit before 2016, but, um, um, um, I, you know, I found really positive engagement and willingness to be open to new technologies. So that was my experience 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.

The UK government announced contracts for difference allocation round eight, which will open in July of this year. This follows AR seven in January, which secured 8.4 gigawatts of offshore wind. The largest UK CFD procurement ever and renewable UK says up to 18 offshore wind farms could compete for this AR eight round now. The amount of wind going in offshore in the UK is astonishing. Uh, AR eight. I haven’t seen any numbers yet of what they think the total gigawatts will be, but it has to be somewhere around the eight range just to keep up with the [00:10:00] expected rate, uh, to meet their environmental targets and electricity targets in the uk. This is changing the way wind is developed in Europe, especially with the UK changing its tariffs and eliminating tariffs on wind turbine parts and components that come into the country. That is going to really improve the economics of wind turbines in the uk. Plus turn out a lot of European countries and companies to to feed the UK energy goals. Is this the right move in, in terms of the government approach? Because a lot of, uh, other auctions that have happened up in Germany all the way up into Scandinavia have not had such success as this recent UK round. Is their model just a little bit different? And maybe the UK approach is, is the winning method with the the CFDs. Rosemary Barnes: We have some in Australia too. The A [00:11:00] CT Australian Capital Territory where I live has the same thing and, um, for at least several years. Recently, I think most years recently we’ve had our electricity prices in Canberra have been reduced while in the rest of Australia they’ve gone up. It doesn’t always happen that way. Um, it depends on, yeah, how expensive. Electricity was compared to normal. But you know, like when the gas, uh, shock was happening and pushing up electricity prices everywhere, it didn’t affect Canberra very much because we already have PPAs for a hundred percent of our electricity from clean sources. So, Allen Hall: but isn’t that the goal at the end of the day to get. Some levelized pricing, which is the allocation rounds are doing, is they’re getting levelized pricing over a fixed period, so you know what your electricity is going to cost you. None of this up and down, like with the gas market in the United States and elsewhere. Rosemary Barnes: My understanding is that it’s the most crucial aspect of that is certainty, so that new projects can get financing.[00:12:00] It’s not actually about it being a, like, whether it’s a subsidy or a payment is not as important as, like, it’s not that that renewable electricity is too expensive and the government needs to subsidize it. It’s that the bank needs to know how, how much you’re gonna get for the electricity that you generate, um, in order to fuel Okay, to lend it to you. And I mean, you can understand why, like, think about. As, um, batteries enter the electricity grid, you, you know, the pricing, the market movements throughout a day are really starting to change. We used to have, you know, like big spikes in price every evening as a lot of gas generators came on. ’cause they’re expensive to run. But now we’re needing less and less of that as we add more batteries. And, you know, people know these. Trends are generally happening, but not exactly. So how can you forecast what your revenue is going to be? Um, if you’re lending billions of dollars to a project, then you want to know that your person you’re lending to is gonna be able to, to pay you back, which they, they can’t if the revenue goes through the floor. So, yeah, my [00:13:00] understanding is that’s, that’s what it’s really for, is to provide the certainty. It’s, it’s like a bit outdated to refer to it as a subsidy. Um, ’cause it’s not always a subsidy. Sometimes it’s the opposite. But what’s really needed is like knowing how much you’re gonna get for the product that you are delivering. I think it makes sense. I just think that like if there’s all this, all the changes that are coming down the pipeline for the uk, it’s a little bit difficult to actually pinpoint where that price is gonna be. Like a sweet spot for all parties involved. Um. Which I think is something that we saw on the PPA side a lot in the US a few years ago. Rosemary Barnes: They had issues in the UK as well, like a couple of auctions ago. Um, they set the price way too low and I mean, they were told leading up to it, no one can deliver a project at this cost and then nobody bid. And it was, it was a real shame because, you know, like it set them back on, you know, that there’s no projects entered the pipeline, um, in that year as a result. But it’s also what’s interesting to [00:14:00] me is that it’s a different price for different. Types of project. So, you know, onshore wind has a, a different safety price than a, um, offshore wind. And fixed offshore wind has a very different price from floating offshore. Solar’s different. They also have special, uh, price for tidal energy. And that to me is a really interesting thing because who is looking at the UK’s energy mix and saying, yep, title energy needs to be part of this, and we we’re happy to pay, you know, 2, 3, 4 times whatever it is, more. For that than for offshore wind. It’s, um, that, that’s interesting to me. How, how they’ve come up with, with the Yeah, like how the mix is going to look. I mean, they don’t control it precisely. It’s not like they say we are gonna have exactly this many gigawatts for offshore wind and exactly this many gigawatts for solar farms. But they do have, um, different prices and different technologies that are targeted. Matthew Stead: Seems like it really relates really well to the energy [00:15:00]security as well. You know, an extra eight gigawatt here, extra eight gigawatt there. I mean, that can only help with energy security, which is obviously a massive topic. I’m not sure how the newspapers has been coping in the last week or so in the us but over here it’s all about rationing of fuel. It’s all about queues at the pump. So energy security is, is definitely a huge topic. Rosemary Barnes: You wanna know where there isn’t a queue. In my driveway when I plug my car into the, the outlet in my garage. It’s been a really, really fun time to be a smug EV owner. I’ve been, um, reveling in it. Yeah. Really, really, really enjoying, uh. And Joan, but I also do think like it’s gonna last, like we, because we still talk about the oil crisis in the 1970s, right? Like that, uh, we, uh, people overreacted and then reverted for the most part pretty quickly after that. With Denmark being one exception, they, they went all in on when consistently after that. Um, but [00:16:00] you know, like this, even if it’s only a few weeks long, this little shock is going to. Make people think, okay, oh, I was super worried that I might have to spend 20 minutes refueling on a road trip instead of 10 minutes. Um, but actually remember that time when I couldn’t even get petrol at all and I had to spend yeah, like half an hour lining up because everyone was freaking out and. Uh, I wasn’t sure if I was even gonna be able to get to work the next week because the Australian government only thinks we need 30 days worth of, um, of oil in reserve. Uh, I, I think that it’s, it’s got to help EV sales and then. The EV sales is only one part of it because you need then also, you know, security of electricity generation. And I mean, in Australia we’ve got our own coal, so we’re not, um, probably ever going to be able to not generate electricity. But, um, renewables is a, is a huge part of that as well, being able to, you know, have cheap, cheap electricity all the time. So I, I do think that. It, it’s got to be, you [00:17:00] know, helping some of these technologies move, move ahead a little bit faster now. Matthew Stead: Yeah, and I also heard that, uh, the UK is sort of patting themselves on the bat for, uh, actually, you know, transitioning and, you know, securing their own, um, energy supply and not being as reliant as some other countries on imports of, of energy. Rosemary Barnes: Yeah. I mean, we’ve had so many opportunities to learn that lesson over the last few years. Right. So. Anybody that just, um, relaxes after this and says, yep, okay, we’re all good. To go back to relying a hundred percent on, on gas is, you know, like, really. Really going to big lengths to nod to not futureproof themselves from the next one. I do. Do we could, would anybody believe that this is the last time that we’re gonna see, uh, a shock like this? I mean, it will happen definitely. Again, Matthew Stead: rather embarrassing, but actually currently I own approximately six EVs. Allen Hall: It sounds like a lot. Matthew, Rosemary Barnes: you’ll have people beating down your door. Share. Share the love around. We need, it Allen Hall: should give taxi rides. [00:18:00] Ubers Matthew Stead: in 2026. I wanna sell, I wanna sell three of them. So this is just. I’m just so happy. Rosemary Barnes: So message ’em on LinkedIn if you need an ev. Now we’re running classified ads in the uptime When new podcast Allen Hall: are they? BMW electrified? BMWs Matthew Stead: no one’s. One’s BMW. Um, another one is, uh, Austin 10. From 1947, Allen Hall: this is an ad. Matthew Stead: The other one’s in Nissan Leaf, uh, NISO leaf with about 16,000 Ks on the clock. Rosemary Barnes: But the first two you converted yourself. Matthew Stead: Yeah, Allen Hall: we can reach out to Matthew on LinkedIn and he will sell you an electric vehicle. He’s in Adelaide and there’s plenty of people listening to the podcast in Adelaide and all around Australia. Honestly, he, he will deliver. If asked, so Matthew Stead, S-T-E-A-D on LinkedIn. Matthew Stead: The BMW that I converted is a 2 0 2, um, from 19 in the the seventies. And, uh, actually BMW um, converted the same car to an electric vehicle for the Munich [00:19:00] Olympics. So yeah, all I did was, um, recreated what. BMW had done back in 1972. Allen Hall: Delamination and bottomline. Failures and blades are 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. Well, south Korean Drone Company Earth Lab built its vision AI [00:20:00]through wind turbine inspections, and I’ve seen hundreds of those in the states. A $10 million defense export deal in 2025 shifted revenue from 80% inspections to. A much larger defense share. Now they have a, a pretty sizable deal, obviously in the Middle East right now, where they’re using their drone technology to be involved in the defense sector. And North Lab I think got driven to that just because, uh, some of their business in the United States didn’t turn out properly the way they expected it to, although they had. Really great technology. In every conference I would attend with Ner lab, like, uh, and they would explain what they were doing. At one point, they were probably three or four years ahead on the, doing your own drone inspections with the little drone and you just buy their software and it would just, it would go up and take pictures of your wind turbine. Didn’t need a separate [00:21:00] pilot. It, it made all things a lot simpler, but that did never seem to catch on. But the technology is there and North Lab does have good engineering teams to develop drone technology. One of the things about this article, which I, I saw the other day, is that North Labs is thinking about their technology in a broader sense. That they’re not just focused on wind turbine inspections. And we see companies that are only tied to wind quite often. The struggle when wind slows down like it’s doing right now, where an Earth Lab is thinking about the problem a little bit differently and saying, I have this technology. It solves a bunch of problems. Maybe we ought to explore those other problem areas and see if we could generate some revenue. And clearly they have. Is that good advice for the wind industry in terms of technology companies is not to just focus on wind, but to think about solutions for adjacent industries? Does that just broaden the portfolio enough where? It keeps your, [00:22:00] it keeps your company viable for longer periods of time. Matthew Stead: This is a huge topic for us because, um, you know, our technologies can be applied to, you know, rail mining defense, you know, so we’ve, we’ve got sensors which can instrument a whole range of things. Like, you know, we can listen for a conveyor belt when it’s failing. We can measure the ice. On the platform next to a railway line, we can measure ice on an aircraft. Um, you know, with our sensors we can do so much. Um, and um, what we’ve decided is that we need to really conquer. Wind in a nice way, as in, you know, actually help the wind industry first. So we really need to, um, you know, focus there. But, you know, we, we’ve all always been sort of dragged into other industries. Um, but, you know, I think being a technology startup is all about focus. Um, but, you know, revenue is hard. Um, you know, gaining traction is hard. The industry [00:23:00] is hard. Um, so I can see why it might be attractive to, to look at other, other verticals. Um, yeah, so it’s, it’s a, it’s, it’s a reality of a technology startup, unfortunately, that you need to look for other applications for your tech. And, and the other thing is, you know, obviously if we can sell our sensors. Into say, mining or, or rail or whatever. Then it can lower the cost and then, you know, that benefits wind as well. Allen Hall: Well, there’s other technology developments can happen in those other industries you could bring into wind makes both avenues possible. Yeah. A lot of industries are gonna benefit from the technology that has been evolved from wind turbines growth into other industries. But it works both ways and it just adds complexity to the business. But to me it’s complexity you have to take on. Rosemary Barnes: Yeah, I’ve worked with a bunch of startups through my career and I’m trying to think of even one that hasn’t had a defense project at some point. It’s very, very common for development, like, um, [00:24:00]technologies that are in development. Is a very appealing avenue to get funds because, you know, defense spends a lot of, a lot of money on developing new technologies. I’m sure that’s true in every country, not just Australia. Um, and they’re also prepared to, like, if you’ve got a capability that they want, they are like, you don’t, it’s not so commercially cutthroat, you know, like they are prepared to pay a lot for something that, um, has unique capabilities. So I do see that that is incredibly attractive to startups, but I really like what Matt said when he said that as a startup you’ve gotta stay focused because that is what the startups that I have worked with in the past nine, outta 10 of them have done the opposite. They’re just like trying to grab any grant that they think that they could possibly, you know, um, apply for. Then they win it and then now all of a sudden they’ve got a project in a direction that is not. Taking them to their actual business. It’s, you know, it’s not step on the way towards their bus achieving their business goals. Um, and it’s like, [00:25:00] what is the startup for? Are you trying to commercialize a technology or find out if, if it’s not possible and stop? Or are you trying to just keep on working on this as long as possible? And I think that, like, honestly, nine outta 10 of the startups that I’ve worked with, it’s the the latter where they just want to keep on doing cool stuff. Then yeah. Grabbing any, any grant that you can to continue working on that. And a lot of them are defense. Um, makes a lot of sense. But I, I do think that, you know, you’ve got to be goal oriented, keep your eyes on the prize and, um, yeah, like Matt said, say focus if you wanna succeed as a startup, Allen Hall: you think that’s a difference between grants and actual business? I agree with you, Rosemary. When you get hooked into a grant that has a particular outcome and you tend to deviate from what the market. Once, because you’re not listening to the market when you’re going through this grant process, but if you’re in a second business area, it may make sense just because you have a customer, you’re learning from that experience. A lot of things between wind and the other industries are similar in [00:26:00]terms of the way they’re structured, the demands, the expectations, the. It’s, it’s close. Rosemary Barnes: Grants are amazing when it’s the right grant, and you shouldn’t choose a grant for the sake of getting the money. You should choose it because it helps you achieve something that you wanted to achieve anyway. Um, I think that that’s what you’ve gotta, gotta consider. Um, and yeah, definitely don’t turn down free money if it’s available to help you, you know, get to where you need to get, but don’t deviate on. A bunch of side quests just because you can get funding for that. Matthew Stead: I think half the battle is that, uh, half the challenge of commercialization is actually the industry. So half, half the challenge is the technology and r and d and making stuff, but the other half is actually knowing the industry, knowing how to price it, knowing the people, knowing where to sell it, you know, knowing the return on investment. So every time you go into a new market, you might think, oh yeah, I’ll just reapply what I’ve already learned. But that’s, that’s. Definitely not true. So your rail is completely different from [00:27:00] wind. Um, in terms of the actual market, the tech, the tech might be the same, the same for, you know, aerospace. Rosemary Barnes: Yeah. I see that a lot with companies that are trying to take a, a technology that they have from another area and try and bring it into wind. And people are always shocked at. At how different, um, wind energy is. I mean, in terms of the physical operating environment, that’s a, a shock for most companies to start with. It’s like, like in several aspects, it wouldn’t be a more harsh operating environment than, you know, sticking something in or on a wind turbine blade and expecting it to last without maintenance for 20, 30 years. Um, but then also just the way that the, the market works. But it’s interesting that you say 50 50, it’s half about the technology. Do you reckon it’s even half? I, I have come to believe that the technology is like, yeah, like really understanding the problem is and, and knowing that there is a need for a solution. Is the vast majority of the way there, there are so many good engineers in the world that they will find, find the solution if they know exactly what problem they should be solving. [00:28:00] I, I reckon it’s less than 50%. I don’t know about 10%, but, um, certainly I don’t think it’s 50 50. Matthew Stead: Yeah. Maybe it depends on what, what stage of development it is and, you know, what, what maturity level you’re at, perhaps. Rosemary Barnes: Yeah. I mean, your company started. From a, um, you, you didn’t just think, Hey, I want, you know, I know a lot about noise. I wonder what technology I can develop with this. You, you started from, Hey, we’ve got a, a, a problem that, uh, I don’t wanna, you know, um, tell your origin story for you, but you started with a, a problem and a potential solution and then, you know, went from there. Right? So, Matthew Stead: yeah, Bre, you know, I, I think B would be happy for me to say his name, Bre, basically throughout a challenge saying. But, you know, technicians can hear, um, blade damage. So, you know, it should be really simple and easy to make a machine to do the same as what a human can do. Rosemary Barnes: And it was simple and easy, right? Matthew Stead: Ah, yeah. It was so easy. Look, look at all that, all that gray hair. Allen Hall: Well, I think that’s the trouble, right? Is that [00:29:00] if you want to be tied to an industry, hopefully you hit it during a peak time. Because there are ebbs and flows to every economy about every seven years. There’s always something cataclysmic that happens. You just don’t wanna be in that down cycle. You want to be in the upcycle and have something ready to go. When the upcycle hits, you’ll see a lot of businesses do that. In the aerospace, you see it quite a bit that they’ll kind of go dormant and then when they feel like the, the economy is going to boom, they’ll ramp up operations real quick and, and try to make their money while the kidding is good. Then slow it down when it’s not. They have taken a, a more longer term perspective on it. Large businesses can do that. ’cause usually they’re stockpiling cash to, to manage that. Small businesses don’t usually have the cash flow to get over those, uh, lean times. And that’s the trouble. I, I think a lot of companies that I know, in fact. Rosemary and I are working on a project and a couple of names of companies that were in [00:30:00] Wind two, three years ago popped up and I thought they had such great technology and the business model was right. It just hit a rough patch. That’s all it was, and that if you revive that technology a year from now, it would still be applicable. You could still sell that product. It’s just trying to manage the cash flow. It’s hard because I, and back to Rosemary’s point. How much of it is the technology? Uh, and I, I say 10%, and I think that’s roughly right from my experience. A lot of it is everything else. Managing the books, managing your risks, people, uh, all that manufacturing, right, all quality, all every, all that’s involved. And it’s, unless you do it, you don’t realize it. It’s hard to see it unless you’re on the inside. You know, the inside. You think every minute is some other. Major calamity that you have to manage. If you don’t manage it right, you may not make it out the other [00:31:00] side. That’s what small businesses are all about. But it’s, that’s what makes it so hard. Rosemary Barnes: Yeah. I know that at Parlo we’re spending a lot more effort on understanding the problems that people need solved, um, rather than developing solutions, which has been a bit of a tough thing for me to. Kind of, uh, stick to because, uh, you know, I’m an engineer. I’ve developed products my whole career and that I, I love tinkering and, you know, like making things work and doing things that haven’t been done before. But I, I, I do think that there is a real, real need for, um, understanding the problem really well, understanding, um, what solutions are available and, and fitting them together. I think that that is actually a really, um, a, a really needed part of the, you know, the whole wind energy ecosystem. Allen Hall: We had a listener reach out from Japan, Sini Kajima, who was a city counselor in one of the cities, in obviously in Japan, who was a regular listener and. He wrote in [00:32:00] about some of the wind turbine installations that are going on in sort of northern western Japan. They’ve installed some eight megawatt turbines about a mile, 1.6 kilometers offshore, and that’s creating a lot of concern for the local residents there. Those are big turbines, and they’re talking about using 15 megawatt turbines to do something similar and. As, uh, advocate for, uh, the, the city he’s advocating, uh, a 10 kilometer minimum setback in the national diet in Japan. You’re gonna see a lot more of this come up, I think. And the pictures that was sent along with it is pretty, um, eye-opening in that you got this really big turbine, really close to shore. Are we going to put setbacks [00:33:00] in as, uh, a regulation or law in some of these territories, like especially Northern Japan where there is great wind resources, amazing wind resources, but at the same time, there’s a lot of people who live there that will like to have some view of the ocean, not just turbines in the water right off the coastline. This is not just a Japanese problem, but it does seem to be a, a big problem ’cause of the, the way the Continental shelf is around Japan, it drops up pretty quick. Rosemary Barnes: Yeah, exactly. It’s not a specific Japanese problem, and I mean, in most cases there’s development approvals and people have plenty of opportunity to express their displeasure at where turbines are cited. But for Japan, it wouldn’t be as simple as saying, okay, we just increase the offset dis distance by a little bit because you increase the, I’m assuming these turbines are cited already as far out as they can be while still being fixed bottom. And if you wanted to push them further away, then you move to floating and you double or triple the cost, [00:34:00] which Japan is looking into floating offshore wind a lot. Um, but Japan. Has no, has no easy options. I mean, Japan likes electricity as much as every other country does. They don’t want to rely on nuclear as much as they have been, which is, you know, probably, at least to a certain extent, understandable. They don’t have great solar resources. I mean, they have some, um, and they could do more. They don’t have good onshore wind opportunities. They have geothermal potential, but they don’t like that so much because their, um, NAL hot springs are, you know, a very important tourism industry and very important culturally. So they’re worried about doing anything that would mess that up. The offshore wind solution, this particular environment haven’t seen, it doesn’t sound like the best situated project, but take any other option that they’ve got for generating electricity in Japan and it has. Probably equal disadvantages. I just think that they have a, a hard problem and [00:35:00] have to choose which compromise they wanna make. Allen Hall: Mr. Kuma brings up a couple of points here that. There’s about 150 residents that are at risk of insomnia from the wind turbine noise, and they’re concerned about the migratory zones for protected wildlife. In this case, geese about five kilometers offshore. Rosemary Barnes: Then there might be birds that are affected, and if they are, they can use technologies to spot the birds. Stop the turbines. Like there’s, there’s, you know. Dozens of success stories, um, related to birds and wind turbines. That’s, that’s a solved problem. The noise, I mean, how far away are they? Matt’s the noise expert. Like how, how far away from a wind turbine do you have to be before you can even hear it over the wind noise? Matthew Stead: Uh, the wind turbine noise is not gonna be an issue. Allen Hall: So then it comes down to sight lines. And Japan has some of the most beautiful coastline in the world. Rosemary Barnes: I mean, I’m not gonna tell someone that they should, like looking at wind turbines, like I would also rather not look at a wind turbine if I could be looking at an ocean view or a mountain view or whatever. But any energy project would [00:36:00] be nicer if it wasn’t there in the first place. Like, you know, there’s not like a beautiful coal power plant to look at. There’s not a beautiful transmission line to look at. There’s not a beautiful petrol pump, um, to look at. Like, none of none. None of these things are like beautiful technologies that we enjoy interacting with on our daily lives, but we prefer to, you know, have the trade off of having that infrastructure. And trade off for the, the benefits that it brings. And, um, you know, there’s, in that sense, there’s nothing different about renewable energy technologies. It’s different, different trade offs, but they’re always gonna be there. Allen Hall: That wraps up another episode of the Uptime Wind Energy Podcast.

During Race Industry Week by EPARTRADE, Jim Campbell, Vice President of Performance and Motorsports Commercial Operations at General Motors, delivers a comprehensive look at GM's expanding global motorsports strategy—from Cadillac's entry into Formula 1 to a new 2026 NASCAR Cup Series Camaro, and the advanced simulation, CFD, AI and powertrain technology driving performance across every series.Broadcast from inside GM's high-performance powertrain facility in Pontiac, Michigan, Campbell explains how this center anchors GM's factory race programs and its Chevrolet Performance parts business—supporting programs in F1, NASCAR, IMSA, FIA WEC, IndyCar, NHRA, off-road racing, and more.
A tight, historic cellar. Arched ceilings. Long corridors. Tiny shafts. We faced a design wall: to keep routes tenable, we needed twice the extraction that the building could carry. At that point, I've failed as an engineer - I've reached my limit and could not find a solution.Some time later, a solution appeared in my head from nowhere —what if the fan changed with the fire? Not in a crude on-off way, but by tracking temperature, exploiting density changes, and chasing constant mass flow instead of fixed volume.We unpack the moment this clicked, the fan physics behind it, and why hotter smoke can actually make extraction easier if you use the margin correctly. You'll hear how we oversized the fan, ran it at a lower frequency in ambient, then ramped as temperatures rose to keep kilograms per second steady. That adaptive control boosted cubic meters per second right when the layer needed support, eased plug-hole entrainment, and stabilised makeup air velocities. We walk through the thermodynamics, the electrical and pressure implications, and how these pieces form a practical control strategy for retrofits and new builds.To ground the idea, we share two paths to proof. First, CFD with user-defined control that reads gas temperature each time step and updates fan frequency with smoothed delays to prevent oscillations—capturing the real feedback loop between fire and system. Then, full-scale container burns with live control showed the same trends from 20 to over 500 degrees: falling duct pressures, lower fan power at heat, and the headroom to increase volumetric extraction without breaking limits. Thinking about it now, this idea is a part of many other concepts that I describe together. To show a way how we come from the simple framework—Smoke Control 1.0 (empirical, static), 2.0 (CFD-informed, still static), into a new smoke control 3.0 (adaptive, feedback-driven)—and explore how this thinking can reshape underground venues, car parks, tunnels, pressurisation, and natural ventilation.If you care about safer evacuation, smaller shafts, lower velocities, and systems that work with physics rather than against it, this story is for you. Subscribe, share with a colleague who designs smoke control, and leave a review with your toughest question so we can tackle it next.Reading material:- Can smoke control become smart?- Transient characteristic of the flow of heat and mass in a fire as the basis for an optimised solution for smoke exhaust- Smart Smoke Control as an Efficient Solution for Smoke Ventilation in Converted Cellars of Historic Buildings----The Fire Science Show is produced by the Fire Science Media in collaboration with OFR Consultants.

In this episode of Energy Transition Today, Leonard and Maja start with the fallout from the UK's AR7 offshore wind auction, looking at record awarded volumes alongside cancelled projects and growing strain on the development pipeline. They then turn to Poland, where RP Global is progressing a highly leveraged, largely merchant onshore wind project, highlighting rising lender confidence in Central and Eastern Europe. The focus moves to the Netherlands and its decision to introduce a temporary one sided CfD to relaunch a 1GW offshore tender and rebuild investor appetite. The episode also examines Germany's newly approved gas capacity programme and what it means for system security, before closing with the surge in battery storage investment, including major equity and debt financings for terralayr in Germany and Greenvolt's grid scale project in Hungary.Hosts: Maya Chavvakula and Leonard MüllerThis epsiode was edited by Leonard Müller.

This week Patrick and Lori welcome Ingmar Jungnickel, an aerodynamicist and the founder of AiRO, a fitting system based on rider aerodynamics. AiRO uses CFD (computational fluid dynamics) to simulate wind tunnel testing to give riders otherwise unaffordable feedback on their bike position.
For most of us getting into a wind tunnel is but a dream. Tunnels are hard to find and harder to afford. As an alternative Josh has recommended the Chung Method. It's proven yet it does take some expertise to get right. What if there were something in the middle. Something that is more accessible and less expensive than a wind tunnel yet doesn't require the hours of commitment and trial and error of field testing? Our guest believes he has just that. AiRO may sound like a company that is trying to latch onto the "AI" craze. But its founder, Ingmar Jungnickel, has been into cycling aerodynamics long before Chat GPT became a thing. He has a degree in engineering, he's developed on-bike aero hardware, and he worked for Specialized where he logged many hours in that company's wind tunnel. All of that, along with a chance opportunity to work with speed skaters, led him to develop a CFD program that attempts to make cycling aerodynamics more accessible. Ingmar's back story includes meeting are own Josh Poertner. But the real story here is how good Computational Fluid Dynamics has become. The potential of AiRO and its date even blew the mind of Josh as you will hear in this episode of Marginal Gains.
AI data centers are no longer just buildings full of racks. They are tightly coupled systems where power, cooling, IT, and operations all depend on each other, and where bad assumptions get expensive fast. On the latest episode of The Data Center Frontier Show, Editor-in-Chief Matt Vincent talks with Sherman Ikemoto of Cadence about what it now takes to design an “AI factory” that actually works. Ikemoto explains that data center design has always been fragmented. Servers, cooling, and power are designed by different suppliers, and only at the end does the operator try to integrate everything into one system. That final integration phase has long relied on basic tools and rules of thumb, which is risky in today's GPU-dense world. Cadence is addressing this with what it calls “DC elements”: digitally validated building blocks that represent real systems, such as NVIDIA's DGX SuperPOD with GB200 GPUs. These are not just drawings; they model how systems really behave in terms of power, heat, airflow, and liquid cooling. Operators can assemble these elements in a digital twin and see how an AI factory will actually perform before it is built. A key shift is designing directly to service-level agreements. Traditional uncertainty forced engineers to add large safety margins, driving up cost and wasting power. With more accurate simulation, designers can shrink those margins while still hitting uptime and performance targets, critical as rack densities move from 10–20 kW to 50–100 kW and beyond. Cadence validates its digital elements using a star system. The highest level, five stars, requires deep validation and supplier sign-off. The GB200 DGX SuperPOD model reached that level through close collaboration with NVIDIA. Ikemoto says the biggest bottleneck in AI data center buildouts is not just utilities or equipment; it is knowledge. The industry is moving too fast for old design habits. Physical prototyping is slow and expensive, so virtual prototyping through simulation is becoming essential, much like in aerospace and automotive design. Cadence's Reality Digital Twin platform uses a custom CFD engine built specifically for data centers, capable of modeling both air and liquid cooling and how they interact. It supports “extreme co-design,” where power, cooling, IT layout, and operations are designed together rather than in silos. Integration with NVIDIA Omniverse is aimed at letting multiple design tools share data and catch conflicts early. Digital twins also extend beyond commissioning. Many operators now use them in live operations, connected to monitoring systems. They test upgrades, maintenance, and layout changes in the twin before touching the real facility. Over time, the digital twin becomes the operating platform for the data center. Running real AI and machine-learning workloads through these models reveals surprises. Some applications create short, sharp power spikes in specific areas. To be safe, facilities often over-provision power by 20–30%, leaving valuable capacity unused most of the time. By linking application behavior to hardware and facility power systems, simulation can reduce that waste, crucial in an era where power is the main bottleneck. The episode also looks at Cadence's new billion-cycle power analysis tools, which allow massive chip designs to be profiled with near-real accuracy, feeding better system- and facility-level models. Cadence and NVIDIA have worked together for decades at the chip level. Now that collaboration has expanded to servers, racks, and entire AI factories. As Ikemoto puts it, the data center is the ultimate system—where everything finally comes together—and it now needs to be designed with the same rigor as the silicon inside it.
In this episode, Jason Pritchard is joined by Lester Erlston, Founder of Flight Kinetics, to explore how advanced aerodynamics could unlock the next phase of electric and hybrid-electric flight. Lester explains how the company's proprietary technology, PropWings, is designed to dramatically improve lift, range, and payload capacity for eVTOL aircraft—without requiring advances in battery chemistry. Instead, the solution focuses on smarter aerodynamics, harvesting previously wasted propeller slipstream energy to enhance performance during critical flight phases such as transition and cruise. During the conversation, Lester outlines Flight Kinetics' journey from initial invention through patent protection and toward a scalable licensing business model. The company positions itself as a future Tier 1 technology licensor, offering an airframe-neutral solution that can be integrated across multiple eVTOL platforms. The discussion dives deep into the technical challenges of designing a high-lift system that is robust, adaptable, and certifiable across diverse aircraft architectures. Lester shares how a phased validation roadmap—progressing from advanced CFD analysis to wind tunnel testing and ultimately flight testing—is being used to reduce risk and deliver the real-world data OEMs require. Looking ahead, the episode explores how improved aerodynamic efficiency can translate directly into safer operations, greater energy margins, longer routes, and stronger economics for operators.

Today we cover another branch of safety of Battery Energy Storage Systems (BESS), that is explosion prevention in mitigation. I always thought you can either end with a fire or with an explosion, and boy I was wrong... but we will go back to this later. Now I bring on Dr. Lorenz Boeck (REMBE) and Nick Bartlett (Atar Fire) to unpack how gas released during thermal runaway turns a container into a deflagration hazard, and what it takes to design systems that actually manage the pressure, flame, and fallout. This is a tour through real incident learnings, rigorous lab data, and the evolving standards that now shape best practice.We start with the fundamentals: from the overview given by NFPA855, why modern BESS enclosures—with higher energy density and less free volume—see faster pressure rise, how gas composition varies by cell and manufacturer, and why stratification matters when lighter hydrogen-rich mixtures sit above heavier electrolyte vapors. From there, we translate UL 9540A outputs—gas quantity, composition, flammability limits, burning velocity—into engineering decisions. NFPA 69's prevention path typically relies on gas detection and mechanical ventilation designed to keep concentrations below 25% LFL, validated with CFD to capture obstructions, sensor placement, fan ramp, and louver timing. NFPA 68's mitigation path kicks in if ignition happens, with certified vent panels sized to the actual reactivity and geometry, relieving pressure and directing flame away from exposures.A major takeaway: the latest NFPA 855 now often pushes for both prevention and protection. Even with active ventilation, partial-volume deflagration hazards remain, especially as cell capacities rise and gas volumes scale up. We dig into venting trade-offs—roof vs sidewall, snow and hail loading, heat flux to back-to-back units—and how targeted sidewall venting can deflect flame upward while reducing weather vulnerabilities. Perhaps most critical, we talk about late deflagrations observed hours into large-scale fire tests, when changing ventilation conditions allow pockets to ignite. Active systems aren't built to operate throughout a long fire, so passive venting becomes essential during and after ignition.Whether you're a fire engineer, AHJ, insurer, or developer, this conversation connects the dots between lab data, CFD, and field realities. You'll leave with a clearer view of how to apply UL 9540A, NFPA 68, NFPA 69, and NFPA 855 in a world of stacked containers and supersized cells—plus where training can shorten your learning curve.

In this episode of the Data Center Frontier Show, DCF Editor in Chief Matt Vincent speaks with Uptime Institute research analyst Max Smolaks about the infrastructure forces reshaping AI data centers from power and racks to cooling, economics, and the question of whether the boom is sustainable. Smolaks unpacks a surprising on-ramp to today's AI buildout: former cryptocurrency mining operators that “discovered” underutilized pockets of power in nontraditional locations—and are now pivoting into AI campuses as GPU demand strains conventional markets. The conversation then turns to what OCP 2025 revealed about rack-scale AI: heavier, taller, more specialized racks; disaggregated “compute/power/network” rack groupings; and a white space that increasingly looks purpose-built for extreme density. From there, Vincent and Smolaks explore why liquid cooling is both inevitable and still resisted by many operators—along with the software, digital twins, CFD modeling, and new commissioning approaches emerging to manage the added complexity. On the power side, they discuss the industry's growing alignment around 800V DC distribution and what it signals about Nvidia's outsized influence on next-gen data center design. Finally, the conversation widens into load volatility and the economics of AI infrastructure: why “spiky” AI power profiles are driving changes in UPS systems and rack-level smoothing, and why long-term growth may hinge less on demand (which remains strong) than on whether AI profits broaden beyond a few major buyers—especially as GPU hardware depreciates far faster than the long-lived fiber built during past tech booms. A sharp, grounded look at the AI factory era—and the engineering and business realities behind the headlines.
In this conversation, Neil Ashton and Prof. Siddhartha Mishra, and Prof. Johannes Brandstetter discuss their recent paper on AI foundation models in computational fluid dynamics (CFD).

Welcome to The Chopping Block — where crypto insiders Haseeb Qureshi, Tom Schmidt, Tarun Chitra, and Robert Leshner chop it up about the latest in crypto. This week, Kaledora Linn, Co-founder and “Empress of RWAs” at Ostium, joins to break down the rise of on-chain equity perps, the funding-rate chaos that hit 365%, and why she believes the next wave of tokenized assets won't come from exchanges—but from structured liquidity markets. We dive deep into Ostium's hybrid CFD model that blends TradFi mechanics with on-chain transparency, explore why most retail traders can't stomach perp carry costs, and debate what “safe leverage” could look like in an RWA world. The panel also touches on CZ's presidential pardon and Coinbase's new Echo platform, connecting the dots between political optics, capital formation, and how crypto's product design is evolving beyond speculation. Whether you're building perpetual DEXs, tokenizing RWAs, or just trying to survive the next funding-rate spike, this episode unpacks how market design, UX, and regulation will shape crypto's next trillion-dollar frontier.

Send me a messageIn this week's episode of the Sustainable Supply Chain Podcast, I sat down with Ollie Taylor, Founder & Director of Marine Futures, to talk about one of the toughest nuts to crack in sustainability, decarbonising the marine industry. Boats, big or small, don't often top climate discussions, yet their materials, manufacturing, and fuel use carry a hefty footprint.Ollie explains how Lifecycle Assessment (LCA) can reveal the true environmental cost of marine products, from resin to recycling, and why so many “green” designs turn out to be anything but. We unpack how his platform, Marine Shift 360, is helping designers and builders make data-led choices early in the design phase, where up to 80% of a product's total impact is decided.We also dive into the data problem: how poor visibility, outdated datasets, and supplier secrecy distort sustainability claims. Ollie argues that transparency, education, and automation are key to bringing LCA into the mainstream, making it as essential as CAD or CFD in engineering.Other highlights include the promise of circular design to stabilise volatile supply chains, the limits of regulation versus commercial pressure, and why profitability and sustainability must align for real progress.If you care about data-driven design, circularity, and cutting emissions at the source, this episode is worth your time.
On Monday, President Donald Trump, Department of Health and Human Services (HHS) Secretary Robert F. Kennedy Jr., and other Trump administration officials announced a pair of actions the Food and Drug Administration (FDA) will take to address the increase in autism spectrum disorder (ASD) in children. First, the FDA will update the warning labels for acetaminophen — the active ingredient in pain relievers like Tylenol — to note a potential association between the ingredient and neurological conditions — such as ASD and attention-deficit/hyperactivity disorder (ADHD) — in children (though it also emphasized that no causal link has been established). Second, the agency has initiated the approval of leucovorin calcium tablets for patients with cerebral folate deficiency (CFD).
