Energy’s brightest innovators. This is the Progress Powering tomorrow. Allen Hall: Michael, welcome to the program.  Thanks, Allen. A pleasure.  Allen Hall: Well, this is gonna be a, a really interesting discussion today because, uh, I don’t know a lot about wave power, but. Obviously the world has made some substantial progress in wind and solar, but the ocean energy is still relatively unknown and. I want you to, just to paint the picture of the problem, what gap exists in renewable energy today that wave energy can fill? Michael Henriksen: Thanks. Thanks. A yes. Uh, that’s right. So ocean energy as such. And we have, um, we are working with the wave energy side of the other things here in Wave Piston has a very large potential because there’s a lot of waves around us. We all feel it when we are out in the sea, when we’re out swimming or whatever.[00:01:00] So what can it fill out that is that, that the, the interesting thing about wave energy is that is, um, timewise shift compared to wind. You know, it’s the wind that builds up the waves. The waves come, uh, the wind comes and goes, but the waves that keep rolling also afterwards. Yeah. So this timewise shift that gives some extra value. Of the energy that you can actually produce at the same time, it’s actually also, it’s a more of stable resource. So you, you don’t have these large fluctuation, it, it, it comes slowly and then dies away slowly depending on where you are in the world, of course. And then the last for the least is it’s very predictable. So stable days advantage, you can actually very precise predict what sort of your energy production profile. So by adding an extra renewable energy source, you can actually sort of, it gives extra value to both have sort as much solar PV as possible, as much wind as possible, but also have wave energy there to have sort of a better, uh, in the end, uh, [00:02:00] uh, energy production. Allen Hall: Yeah. And that, and the technology is really applicable to, uh, a lot of regions, uh, around just like island communities and places of a little more remote. Uh, because the cost of electricity on islands is incredibly high. They’re buying diesel usually, and they have a kind of a, a double problem in that they have to buy diesel to run electricity plants, and then at the same time they’re, they’re having to make fresh water all the time ’cause fresh water’s a problem. Wave Piston solves both of these problems together. But why are we in this? Space right now. I, I just wanna back up a minute. I mean, there, there does seem like for the last 30, 40 years that I can remember, the island communities have been really stuck. Solar hasn’t really filled the void. Wind has been intermittent option at times. Why waves?  Michael Henriksen: Yeah. But that’s actually, uh, where we see our, like our step to, uh, [00:03:00] you know, uh, go to market strategy, so to speak. See, that is the first step because as you mentioned, all the island communities, I would also say remote coastal communities still have this, this challenge of being dependent on fossil fuels. And as you know, it’s, it’s mainly because of course you have limited, uh, uh, uh, land space. Uh, of course they should have as much solar PB as wind as possible, but you still have this, you know, you don’t wanna have it in your backyard. It’s difficult to have, you know, spatial beautiful islands where you have, uh, tourism, et cetera. And then you have, uh, solar PB and winter turbines all over the place. It’s not gonna happen. So they’re looking at to go to, of course, offshore. What they have a lot of us is they have ocean. Yeah. And the challenge there again, is. Most places when you go just a few kilometers from shore get very, very deep. Yeah. So you need to find something that is sustainable, something that it will not spoil the view. Something that is actually, uh, uh, an [00:04:00]environmental friendly way, you know, of harnessing the energy that that is where wave energy come into the picture because. It’s happening below the sea. So the, the surface and, and, and the, it can sort of coexist with other things happening there. Of course, you need to have an area where just say this is for wave minute. Yeah. But you don’t, so sort of spoil view. You don’t have this issue with the, not in my background as such. So, so, so by coming in, of course we will be at another cost level to begin with. Yeah. By coming in, taking that part of it, then we can actually be a part of solutions for these remote islands and the coastal communities. Allen Hall: Well, because some of these islands are spending more than 10% of the GDP just on energy to import it. That’s. Really high and a, on a big burden on the economy is how do you see wave piston affecting that?  Michael Henriksen: But it’s just actually that is this, uh, it’s, it’s both, you know, in the first phase, of course, the islands in milk richi, but also you can say [00:05:00] countries as such that are dependent on fossil. Because you can just reduce your dependency and also these volatility of the price. Uh, but, but go coming back to wave piece, of course we, uh, the special thing about our system is that we actually, we can both produce electricity and we can also desalinate sea water ’cause it’s hydraulic system. So this about coming into an island community where they have both these challenges. We can actually come with a double. Sort of a, uh, solution and then, uh, work with how much energy you need, how much water you need at a given time. It could be an off grid solution or an on grid or micro grid, whatever, where, where, where. That makes sense. Yeah. So coming in and that’s actually why there is a big uh, uh, sort of. Focus on wave, not only on us, but also others in the sector, that we can be a part of the solution, which is actually when you come with a new thing, you need to sort of to say, okay, this is new, this is fantastic. But you also need to say, okay, we are part of the solution now. We are solving some of the problems you have. We’re not [00:06:00] creating new ones. Or maybe you not, not, there’s always some challenges, but we are not creating that many of big ones. You know? We are solving things. Yeah, we’re solving. Your challenges?  Allen Hall: Well, e even if you look beyond the island, island economies, uh, there’s a bigger picture here about renewable energy sector that is not really considered wave energy too much, especially for offshore wind, right? There’s, uh, uh, offshore wind, particularly in the North Sea and off the coast of England and other places where there’s our massive wave resources. We haven’t really addressed that at all. Are we missing out on a, on a lot of energy production? That would be relatively easy to go get.  Michael Henriksen: We are missing out. That’s the, the, the short, the short, uh, uh, answers there. Of course, we see relatively easy need to look at the relatively side of it because it is difficult going offshore. You know why? But it’s also why I’m asking. It’s actually why it hasn’t wave energy succeeded so far. Well, that’s simply because it’s [00:07:00]not the low hanging fruit. Now being able to take a wind turbine. You know, in Denmark it was the farmer. You could just go, or the local Smith blacksmith go, go and fix things. Now we need to go offshore immediately. You didn’t throw the wind turbines in the middle of the North Sea in the first place? No. So this of course, solving the issue with. The survivability someplace. Sometimes you have really extreme large weight, large, uh, forces you need to work with. You have your ability, you know, you have this, that, that there are millions of cycles in the corrosive, uh, environment. So all that of course you need to, uh, design the system to handle and still being able to, you can see through cost trajectory will get you down to, to a competitive cost limit. So of course, yes, we’re missing out. Uh. There is a large, uh, uh, sea space, especially in the, all the newer, uh, offshore wind turbine areas because they take up a lot of space. They have very large, beautiful wind turbines, but you have a large sea [00:08:00] space in between where you can actually use that for energy production. So, so yes. That’s, uh, definitely a large of opportunity.  Allen Hall: Well, so let’s talk about what Wave Piston has built. Can you walk us through what the Wave Energy system does, kind of how it works in simple terms and what makes it different from some of the earlier Wave energy devices that have been tried over the years? Michael Henriksen: So, so we, uh, in Wave Piston is actually going a bit back to the, the whole old style. It was not me actually, that’s the clever one There is by colleagues in, in, in, in Wave Piston. So, uh, but they, they was general analyzing. What are the, the challenges, you know, or has been the challenges, uh, on, on Wave 80. Why haven’t we succeeded so far? And it, what they came up with is actually this brilliant concept we have now that is so hard so far, not so. Put it in a, in a labor perspective. Something also I und

    UK Bans Ming Yang, Vestas Plans Scotland Factory

[00:00:00] The Uptime Wind Energy Podcast brought to you by Strike Tape, protecting thousands of wind turbines from lightning damage worldwide. Visit strike tape.com. And now your hosts. Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host Allen Hall, and I’m here with Rosemary Barnes, Matthew Stead, and Yolanda Padron. And. The hot news this week is Scotland, and Scotland is gonna be a major hub for manufacturing for all the offshore wind that is happening in the UK and around Europe. Well, the UK government ruled that Chinese turbine maker Ming Yang poses a national security threat and blocked its products from UK offshore wind projects, which in turn killed a plan for a one and a half billion pound Scottish factory. And then a couple of hours later, Dana Danish Giant Vestus announced plans to build its own cell [00:01:00] and hub factory in Scotland with an investment of about 250 million euros and up to about 500 jobs. Uh, but there is still a catch. Vestus is only going to move forward if it wins enough orders from the UK’s offshore wind. Auction program and allocation round eight was announced recently, so that’s gonna happen. So obviously Vestus would like to win a number of turbine orders from that, but that’s a pretty major announcement by the UK and by Vestus. It does seem like Vestus will be the leader in offshore winds in the uk. Is that the long term play now? Is that there’ll be a primary. Wind turbine source for the uk and that would be Vestas.  Rosemary Barnes: Weren’t we just covering, didn’t we just cover last week about another Danish manufacturer who just closed in a cell, uh, manufacturing facility in Denmark? Allen Hall: Siemens did.  Rosemary Barnes: So yeah, one week [00:02:00] Siemens is closing a factory in Denmark and the next week. As Bestus is opening similar factory in the uk. So that’s a interesting little geographic, uh, bit of information,  Matthew Stead: isn’t it? Thanks to our friends, the royal family in the uk, that they’re really promoting offshore wind. Matthew Stead: Uh, my understanding is they own the rights to the offshore water. Uh, well, obviously the offshore, offshore area, and they, they have promoted, um, the use of leases. And I, I understand, I might be cor incorrect, that the royal family is the one that may gain the, the benefit from the leases.  Allen Hall: It’s the crown of state in the UK that. Manages the royal family’s holdings. [00:03:00] Some part of the awarded amount or the, the leases are going to go to the royal family. I forget what that number is. Maybe 10% of ’em. And the rest basically are the treasury of the uk.  Matthew Stead: Oh, not all of it.  Allen Hall: Yeah, not all of it. But yeah, I mean it definitely benefits the royal family.  Matthew Stead: Yeah. So kiosk to the royal family for promoting it.  Allen Hall: Well, the price of petroleum in oil products recently has skyrocketed, of course. And, uh. The push to get renewables as the leading source of electricity generation in the UK is a massive move, which will. Promulgate all through Europe, everybody’s gonna be on that same pathway, I would think. Right now, the, the, the unique part about the UK and these, these Scottish efforts is that the speed at which the UK and Scotland in particular are going after it, you see some commitment by the Scandinavians in Germany to get to some of these numbers. But, uh, the UK is putting in an action. And they have a in, uh, industrial growth plan, which [00:04:00] is a little bit unique that this is part of the growth strategy of the UK is they’re trying to grow jobs, they’re trying to get higher paying jobs into the uk and this is the, the one way they’re trying to accomplish it. I was listening to a podcast today talking about this. It was someone representing, I think it was great British energy, but they are at least the, as the discussion points, they were trying to show comparisons. To what will happen and when to What has happened in the past with aerospace that the UK realized it’s good at composites, manufacturing wings, doing power plants, rolls Royce is there, right? So there’s a number of parallel. Tracks that the UK is going to to try to do through, um, their knowledge of aerospace into the wind turbine market. We’ll see if that comes to fruition. I’m not sure where these vestus turbine blades are gonna be built. They’re gonna be V 2 36 turbines, 15 megawatt machines out in the water. I, I assume that the turbine blades are gonna be coming from outside the [00:05:00] uk, but maybe the UK is working on something with Vestus about that.  Rosemary Barnes: I don’t know, but, but the UK government with their auctions has definitely laid the framework that would enable manufacturers to make that sort of investment or that, that sort of investment decision. So it wouldn’t, wouldn’t surprise me if we saw more manufacturing there. They’ve got, you know, the most secure, uh, and long, long term pipeline, more the most visibility around. Future projects. So if I was a company looking for, you know, where am I gonna open another factory, that would probably be quite appealing. That security really helps when you’re planning out a factory to know that you’re highly likely to have orders filling it for, you know, the lifetime of the factory. Even if costs are a little bit higher, I think that it would be, you know, you can offset a certain amount of cost by. The certainty.  Allen Hall: What are the short term ramifications for Chinese wind turbine manufacturers in Europe? Are you gonna see [00:06:00] more of these type of moves like the UK just did today, where they’re gonna put some prohibitions in? Or will there be some places that, uh, Chinese manufacturers can set up base?  Rosemary Barnes: To me, it’s really strange because it’s, it’s like you’re worried about security, so you don’t let them come bring their technology to your country. It’s. Like the, to me, the obvious thing is the other way around. If they’re worried about, um, technology transfer and IP theft, that they, um, should have prevented European wind turbine manufacturers from sitting up factories in China, because surely that’s how the big transfer of knowledge happened. Now China, you know that that’s where, that’s where they learn how to make win winter turbines 10, 20 years ago. Um, and what they’re doing today in China is, is not, it’s not like static from that. They have also developed their own, you know, their own ideas and taken the technology in a different direction. Why don’t we take the opportunity to learn from that? I, I find it a bit, [00:07:00] a bit funny that, um. Yeah, that you would ban a manufacturer from coming to your country because you’re concerned that they have, um, you know, copied or stolen your technology in the past and can’t see how they’re gonna do that by bringing their tech to your country. Matthew Stead: And how does that tie in with the discussion we had the other week about the tariffs and removal of tariffs on certain components? Um, Alan, do you know if that’s linked at all?  Allen Hall: I don’t think it’s linked. There hasn’t been any news articles about it. However, there’s gonna be a lot of hard choices made about where components do come from. That does seem like the UK government is thinking about what components can be made in the uk where UK engineering and technology can be applied to, to change the marketplace and where they want to go buy components. Uh, are they gonna buy them from China or are they gonna buy them from Poland or somewhere in Eastern Europe or somewhere in South America? There’s a lot of places to buy components today. Or India. I think India is obviously, uh, one of the top choices, [00:08:00] right? Just because it was a colony years ago. And there’s a relationship there between the UK and India. Is that where the technology transfer begins? Uh, instead of it with China? Probably so 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 into the label 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.[00:09:00] Alright, how tall is too tall? Well, for onshore wind, the answer keeps changing with. Nordics group just receiving its first order for a turbine with a hub height of. Drum roll please. 199 meters. So there must be some sort of limitation at 200 meters is where the limit is. So they came in one meter below it. It’s what it smells like.  Rosemary Barnes: The limitation would be on the tip height, not the hub height.  Matthew Stead: Should have been 200,  Allen Hall: just routed up to 200. See?  Rosemary Barnes: Yeah. But this is Germany, right? Where it’s lik

    Britain Breaks Wind Record, Ørsted Exits Floating Project

    Allen covers the UK’s all-time wind record, the Crown Estate’s new 6 GW leasing round, Port Talbot’s floating wind assembly port, and Ørsted and BlueFloat’s exit from the Stromar project.

And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Good Monday everyone! Last Wednesday, the British Isles did something remarkable. Wind turbines across the United Kingdom generated twenty-three thousand eight hundred and eighty megawatts of electricity — an all-time national record. That is enough to power twenty-three million homes at the same moment. And while wind was hitting its record high, natural gas fell to just two-point-three percent of total British supply. A two-year low for gas. In a single day. Britain is not stopping there. The Crown Estate has announced a new offshore wind leasing round, targeting six gigawatts of new capacity off the northeast coast of England — enough to power six million more homes. And now the United Kingdom is building the physical infrastructure to match that ambition. Ministers have committed up to sixty-four million pounds in support for Port Talbot in South Wales. The plan: the UK’s first dedicated assembly port for floating offshore wind. Associated British Ports says total investment could exceed five hundred million pounds once fully built out. The goal is the Celtic Sea, where developers are targeting four gigawatts of floating wind. Four gigawatts. Floating. In open ocean. Floating offshore wind is the industry’s next frontier. But it is also the industry’s most expensive and complicated technology. Consider what happened quietly this last week off the coast of Caithness, Scotland. Ørsted, the world’s largest offshore wind developer, and BlueFloat Energy have both walked away from the Stromar floating wind project. Stromar is a one-point-five gigawatt floating wind farm — sixty to one hundred meters of water depth, fifty kilometers offshore, enough power for one-point-five million homes. Construction was not expected to begin until twenty twenty-eight. Now Nadara, the project’s remaining partner, holds one hundred percent of Stromar alone. For Ørsted, the exit signals tighter capital discipline. For floating wind, it signals just how difficult the economics remain. And yet, across the North Sea, a solution is taking shape. The University of Strathclyde and Japan Marine United signed a Memorandum of Understanding last week. Their mission: standardise and mass-produce floating offshore wind turbines. Japan Marine United has been developing floating wind technology since 1999. Their Jade Wind floater is headed for large-scale government-led deployment in Japan. Standardisation — the same answer that made fixed-bottom offshore wind competitive. So here is where we are. Britain just broke its wind generation record. The Crown Estate is opening new ocean for development. Port Talbot is becoming a floating wind assembly hub. And Strathclyde and Japan Marine United are building the engineering knowledge to make it all affordable. Two companies stepped back from Stromar. But the Celtic Sea is still waiting. And that’s the state of the wind industry on the 30th of March 2026. Join us tomorrow for the Uptime Wind Energy Podcast.

Energy’s brightest innovators. This is the Progress Powering Tomorrow. Allen Hall: Dainis and Janis, welcome back to the program.  Dainis Kruze: Thank you, Alan, for visiting us, uh, in, in our new facility.  Allen Hall: Yeah. Is a great new facility. We’re in Denton, Texas, which is just north of Dallas. Uh, and you move from. Lake Dallas area. Mm-hmm. And we had visited that facility a year or so ago. This new facility is amazing. It’s what, probably four times the size. Yeah. Maybe a little bit bigger. And it is, uh, indicative of the growing business that Aeros has in the United States. And that’s wonderful. Uh, and I’m glad I could catch you in Texas ’cause I know you, you guys are running around the world all the time. Uh, I think the last time I was at. A facility with both of you was over in Riga?  Dainis Kruze: Yes.  Allen Hall: Uh, probably two years ago now. Oh,  Dainis Kruze: yeah.  Allen Hall: So I saw the Riga operation and, and now we’re seeing [00:01:00]the, the Denton US operation. You have facilities in other places too, right?  Dainis Kruze: A small one in Australia, but, but yeah, the main facilities in Riga and the second biggest one here in, in Dallas. Allen Hall: A lot of technology changes since Rose Riga. Uh. Leading edge being the big one, leading edge protection materials. And when I talk to US operators, even operators in Australia, we’re just there. They love the idea and the application of a robot for leading edge repairs.  Dainis Kruze: Oh yeah,  Allen Hall: it makes total sense. It’s one of those areas that, uh, Rons has shown you can do this with a robot much more consistently. Has that business grown quite a bit since you first started it?  Dainis Kruze: Oh yeah. Oh yeah. We did more than 500 turbines last year, so we. The plan for this season is about one and a half thousand turbines, so it is growing quite a lot.  Allen Hall: So the, the speed and the quantity of robots here in the United States is must have grown considerably. Dainis Kruze: Oh, yeah. Uh, one team now gets [00:02:00] up to 15 turbines a month. So if it’s category one or two turbine, uh, leading edge, uh, erosion, it’s about one day to do one turbine category three. Uh, one turbine is being done in two days, and we are talking about like 12 meter repair. It’s not a spot repair, it’s a full repair, like  Allen Hall: full repair. Okay.  Dainis Kruze: Yeah.  Allen Hall: And the robot technology and the, the amount of technology on the robot is behind us has grown quite a bit. Uh oh. Yeah. You’re learning as you’re going. Obviously. I looked at a number of robots in at the Denton facility. Smarter robots. More data, more consistency. Particularly because the leading edge protection materials require a lot more care than rope technicians can generally create on site. Right. Walk us through what this robot is doing, why it’s doing what it’s doing, and, and like the, the quality you get coming out of it. ’cause what I see behind me is really nice. Better than, than [00:03:00] what I’ve seen typically coming out of a factory.  Janis Putrams: Yeah. So multiple things actually we’ve been. Kind of what we’ve been hearing sometimes is that, um, that material’s good, the application seems good, but then it comes off after some time and you don’t understand what’s what happened, right? Yeah. So we understood to, to make it right. We need to make sure that both the kind of, we take the full ownership for the, for the whole process, for the application. And so we’ve been investing quite a lot in our lab to, to actually understand what the material needs, how the surface needs to be, be prepared. How do we measure it? How do we make sure the process is right? So actually what we saw is that, yeah, making sure adhesion, uh, is, is right, is is very important part. Also, when you go out there, there’s a quite a spectrum of the weather forecast, like information. You have humidity, you have temperatures, and you need to be able to guarantee the, the, yeah, the output in all of that spectrum. So yeah, we’ve done quite a lot on, [00:04:00] uh, on those. And  Allen Hall: so from a technology perspective, you’re incorporating all those measurements actually into the robot. So you know what the temperature was when the application was made, you know what the humidity was, you know what the mixture was exactly. Remember the temperature of the, the ingredients that went into make the, the LEP material. That’s remarkable. And now it’s, uh, I think a lot of people think of LEP as being something you would apply with a, you see it still, you see it with rollers and sort of. Basic human tools. You’re spray coating today. Yes.  Janis Putrams: Yes.  Allen Hall: And the, the smoothness of that coating is remarkable.  Janis Putrams: Yeah. For example, I dunno if you, if you know in factories where the cars are made Yeah. You don’t see people rolling the car. Yeah. So, because the, the spraying technology, it enables us to actually guarantee the robot when it moves, it moves in a constant speed. It’s not manually, it’s kind of on a cruise control. So it’s, it’s moving in a constant speed [00:05:00] and the spraying is constant. And so yeah, the, the thickness is, is, is always the same. And also it kind of nicely tempers off on the, on the sides. So there’s no vortexes, kind of, no aerodynamics loss. Uh, so yeah, it, it comes out very, very nice and  well.  Allen Hall: That’s the thing about when you put a leading edge coating on, a lot of times there’s a taped edge or a hard edge there. And then they gotta come back and try to fill it. Or maybe they don’t fill it and the filler doesn’t stay. It may. I’ve seen all varieties of that. So when you spray coat it, not only do you get a very smooth finish, aerodynamically, you lose the step on the backside. Right. So the, the entire assembly is, is just more aerodynamic. And that’s the reason you’re doing in the first place. Mm-hmm. It’s not just we’re recovering this shape. Yes, you’re recovering the shape, but you’d like to get some more power outta your, your turbines. That makes sense to me. When you’re, uh, cleaning the blade too. There’s a lot of technology about just getting the blade prepped because we’ve seen so many times where a leading edge coating’s been applied to a very [00:06:00] poorly prepped blade surface, and it just doesn’t stick. A year later, you’re out doing it again. Describe what you’re doing on the prep side.  Janis Putrams: Yeah, so what we also see, uh, saw that, um, if there’s some damaged material, it’s very important to get it off. If you put it on top of the damaged material, it’s just not gonna hold. So we have one of those robots, it has quite a powerful kind of belt sanding tool, uh, where you can truly take it off. And then the second tool prepares the surface and also the tool kind of makes sure that it’s not up to the, to the operator to choose which point to, to prepare, but just the tool goes in, in a single step and prepares all of it so we can kind of. Be sure that nothing’s missed. And then when you, when you put it on, uh, then, then what’s gonna, it’s gonna hold. Dainis Kruze: And to develop that tool. We have a laboratory where two chemical engineers are actually working and testing and doing pulley tests and surface, uh, adhesion tests [00:07:00] and, uh, to get the result, the best result possible. Because, as Ian said, we’re taking, we, we are giving guarantee, uh, of our work. Uh, and we don’t do that. Oh yeah, it peeled off because the material was bad. We, we, we take the guarantee of application and materials that it’s gonna be stick, uh, is gonna stick and it’s gonna stay there.  Allen Hall: I think there’s a lot into that. And having been to the Riga facility, I understand you have a lot of capabilities there. When we talk to. Independent service providers and they’re applying materials. They’re not doing all the research. Oh, yeah. That aone is doing. You, you are actually looking at material properties, you’re looking at surface conditions, you’re looking at the chemical reactions that are happening. You’re doing the mechanical pull test. You’re putting engineering behind it. Oh, yeah. Which, which has to happen. We’re still early in this leading edge protection world. We have, we don’t have 50 years of experience. We have two or three really good years, and we’re still learning and there’s a lot of different materials being proposed right now. That mechanical testing and evaluation [00:08:00] laboratory really raises the bar.  Dainis Kruze: Oh  Allen Hall: yeah. I think in terms of just what you’re expecting to get out and, and EC saying, you back up what you do. Oh yeah. Which is completely different than the rest of the industry. De describe what that means to an operator that chooses their owns to do leading edge protection. Dainis Kruze: Yeah, it’s a turnkey, uh, solution, right? So, uh, you won’t get in a situation when, um,

Visit strike tape.com And now your hosts. 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. [00:09:00]

    UK Unlocks 10 GW Offshore Wind, Revolution Wind Powers Up

    Allen covers Britain’s radar fix unlocking 10 GW of offshore wind, Revolution Wind delivering first power off Rhode Island, typhoon-proof turbines rising in the Philippines, and an Iowa bill to dim turbine lights at night.

Here’s the wind energy stories you need to know. For years, offshore wind developers in the United Kingdom ran into an invisible wall. Not weather. Not financing. Radar. Military air defence radars could not distinguish a wind turbine from an aircraft. So certain stretches of British waters were simply off-limits to offshore development. Not anymore. The UK government has purchased specially designed air defence radars built to coexist with offshore wind farms. Installation begins in early 2029. Ten gigawatts of previously blocked offshore wind capacity, now unlocked. That follows the largest single offshore wind procurement in British and European history — 8.4 gigawatts, at a price forty percent lower than new gas. Enough to power twelve million homes. And the UK is not stopping at the water’s edge. The government has also proposed removing planning permission requirements for small onshore turbines up to thirty meters tall, no bigger than an oak tree. Farmers. Schools. Factories. All of them able to generate their own clean power on site. No planning application required. Now, let us cross the Atlantic. Off the coast of Rhode Island, the Revolution Wind project is delivering on a promise that once seemed very much in doubt. On March thirteenth of this year, Revolution Wind delivered its first power to the New England grid. The project is led by Ørsted, the Danish offshore wind leader, alongside Skyborn Renewables. As of March sixteenth, the project stood ninety-three percent complete. Sixty-five turbines, each one eleven megawatts, manufactured by Siemens Gamesa. When fully operational, Revolution Wind will power more than three hundred and fifty thousand homes in Rhode Island and Connecticut. Let us go somewhere you might not expect to find wind energy news today. The Philippines. Spanish firm Acciona Energia has installed the first turbine for its Kalayaan 2 wind farm in Laguna province, in the Philippines. One hundred and one megawatts. Seventeen turbines, Goldwind GW 165 units, each one six megawatts, with blades spanning one hundred and sixty-five meters. Every one of them designed specifically to survive typhoons. Structural reinforcement. Smart control algorithms. Advanced sensors to protect infrastructure during storms. Commercial operations are scheduled for December of this year. When that happens, roughly two hundred and fifty thousand tonnes of carbon dioxide will not enter the atmosphere, every single year. And finally, back home in Iowa, a bill is moving through the statehouse that has nothing to do with megawatts. It is about sleep. Iowa House File 2081 would require wind turbines across the state to use aircraft detection lighting systems. Instead of blinking red lights all night long, the lights would only activate when radar detects an approaching aircraft. The bill’s sponsor, Representative Dean Fisher of Montour, put it simply. His constituents used to enjoy a quiet sunset view. Now they stare at rows of flashing red lights through the night. About twenty-seven percent of Iowa’s turbines already have the sensor-based lights. The rest are being upgraded, year by year. The American Clean Power Association registered undecided. New projects, they said, are already planning to use the sensor lights. But retrofitting existing turbines? That cost goes straight to the customer. No groups registered in opposition. Even the environmental advocates said yes. And now you know the rest of the story. From British radar systems finally making room in the sky for offshore wind, to a court-rescued project delivering first power off Rhode Island, to typhoon-proof turbines rising in the Philippines, to an Iowa lawmaker who just wants his neighbors to sleep — wind energy in 2026 keeps moving forward. And that’s the state of the wind industry for the 23rd of March 2026. Join us for the Uptime Wind Energy podcast for more.

    Sunrez Prepreg Cuts Blade Repairs to Minutes

    Bret Tollgaard from Sunrez joins to discuss UV-curing prepreg that cuts blade repair time by up to 90% and has recently received OEM approval. Sign up now for Uptime Tech News, our weekly newsletter on all things wind technology. This episode is sponsored by Weather Guard Lightning Tech. Learn more about Weather Guard’s StrikeTape Wind Turbine LPS retrofit. Follow the show on YouTube, Linkedin and visit Weather Guard on the web. And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Allen Hall: Brett, welcome back to the program.  Bret Tollgaard: Thanks for having me again.  Allen Hall: So a lot’s happening at sunrise at the moment. Uh, there’s, uh, activity with sunrise materials on a lot of blades this year. Over the last couple of years actually, ISPs, operators, OEMs, are realizing that UV curing is a huge advantage.  Bret Tollgaard: Turns out there’s a lot of value added, uh, to the entire process when utilizing UV cure, uh, pre-req.  Allen Hall: So the, the pre pres are, have been available for a couple of years. The qualification though was always the concern. Has the OEM qualified this material? Are they gonna give you the blessing? Does this show up in the manual? If I call the OEM, are they gonna say they have talked to you guys? A lot of those hurdles have been cleared at this point.  Bret Tollgaard: Yeah, great question. And we are happy to announce that we have finally been approved by a large OEM for use on the epoxy blade for now all general kind of repairs. We have several more OEMs that have already passed their phase one mechanical testing, and we’re iterating through now [00:01:00] their, uh, secondary and tertiary kind of tests. And so we do expect to be fully qualified by several OEMs before the end of the year, which should make the ISPs integration and utilization of our materials much, much easier. Allen Hall: So the, the, the problem you’re solving is repairs in the field for the most part, or sometimes in the factory. Mm-hmm. But a lot of times in the field that those repairs. It happened quite a bit. They’re the same repair, the same area, the same kind of thing over and over and over again. And wetting out fabric on site takes time. Particularly if you’re using standard materials, you have to bag it. You have to apply heat in some cases to get it to kick, and then you have to wait several hours for it to cure. So in the repair cycle time, most of your time is waiting.  Bret Tollgaard: It sure is. Uh, and on top of all that, we all know that there aren’t enough technicians in this industry to even do all the repairs, uh, that would like to be done. Yeah. And so to really kind of streamline all of that, [00:02:00] uh, we’ve rolled out a couple of new things and we’ve had a lot more interest in some pre consolidated preki patches for customers. Uh, if a particular blade model has an issue that is a standardized kind of repair. We’re actually now building custom prepregs, or we will build the appropriate width length, stack it, consolidate it, uh, wrap it between our films. So then all the customer has to do when they get on site is, uh, you know, do do the appropriate surface prep. Scarfing, apply a little bit of our UV surface primer to the backside of that patch. But now they can go up tower, single peel, stick, roll out, and then they’re cured.  Allen Hall: And that’s a. How many hours of saving is that? It’s gotta be like six, 12 hours of saving, of, of  Bret Tollgaard: labor. It’s upwards of 80 to 90% of the labor that’s gonna actually need to be done to apply that. Otherwise, and then same thing too. We’ve had a couple instances where we took a several day repair down to one, to two to three hours. And these are multi-meter long repairs that were fast tracked because we pre consolidated preki [00:03:00] everything. Some were in flat sheet forms, some were much longer on rolls, where you’re actually then rolling out with a team. Um, and so we’ve been able to demonstrate several times, uh, over the last 12 months, uh, the, the value that a UV cure preprint.  Allen Hall: Well, sure, because that, that would make sense. The issue about wetting out fabric in the field you just done in the back of a trailer or something, somewhere like that. Usually it is, it’s that you’re never really sure that you got the fabric wetted out. The experienced technicians always feel like, have done it enough that they get very consistent results. But as you mentioned, getting technicians is hard and, and there’s so many repairs to do. So you’re doing those wetting out composite things takes practice and skill. Just buying it, preki it, where you have control over it. And you guys sell to the military all the time. So that, and you’re, are you ass 91 qualified yet? You’re in the midst of that?  Bret Tollgaard: So we, I mean, a, we just got ISO certified, uh, at the end of last year in December. So our [00:04:00] QMS system and everything like that’s up to date, that’s huge. Another big qualification for the OEMs that want to see, you know, true quality and output.  Allen Hall: That’s it. I, if I’m gonna buy a preki patch, so, uh, uh, that would make sense to me, knowing that. There’s a lot of rigor as a quality system. So when I get out the the site and I open that package, I know what’s inside of it every single time. Bret Tollgaard: Well, and that’s just it. And like we got qualified based on the materials that we can provide and the testing that’s being done in real world situations when you’re wetting out by hand and you’re vacuum backing and you’re trying to cure. It is a little bit of an art form when you’re doing that. It is, and you might think you have a great laminate, you got void content, or you haven’t properly went out that glass ’cause humidity or the way the glass was stored or it was exposed. The sizing and the resin don’t really bite. Well. You might think you have a great repair, but you might be prematurely failing as well after X cycles and fatigue. Uh, simply because it’s not as easy to, to truly do. Right? And so having the [00:05:00] pre-wet, uh, pre impregnated glass really goes a long way for the quality, uh, and the consistency from repair to repair. Allen Hall: Well, even just the length of the season to do repairs is a huge issue. I, I know I’ve had some discussions this week about opening the season up a little bit, and some of the ISPs have said, Hey, we we’re pretty much working year round at this point. We’re, we’ll go to California. We’ll go to Southern Texas. We’ll work those situations. ’cause the weather’s decent, but with the sunrise material, the temperature doesn’t matter.  Bret Tollgaard: Correct. And I was actually just speaking to someone maybe half hour ago who came by and was talking about repairs that they had to do in Vermont, uh, in December. They could only do two layers of an epoxy repair at a time because of the amount of the temperature. Allen Hall: Yeah.  Bret Tollgaard: Whereas you could go through, apply a six or an eight layer pre-reg cure it in 20 minutes. Uh, you know, throughout that entire length that he had and you would’ve been done. That’s, and so it took several days to do a single repair that could have been done in sub one hour with our material.  Allen Hall: I know where those wind turbines are. [00:06:00] They weren’t very far from, we used to live, so I understand that temperature, once you hit about November up in Vermont, it’s over for a lot of, uh, standard epoxy materials and cures, it is just not warm enough.  Bret Tollgaard: Yeah, we, we’ve literally had repairs done with our materials at negative 20 Fahrenheit. That were supposed to be temporary repairs. They were installed four or five years ago. Uh, and they’re still active, perfectly done patches that haven’t needed to be replaced yet. So,  Allen Hall: so, because the magic ingredient is you’re adding UV to a, a chemistry where the UV kicks it off. Correct. Basically, so you’re, it’s not activated until it’s hit with uv. You hit it with uv that starts a chemical process, but it doesn’t rely on external heat. To cure  Bret Tollgaard: exactly. It, it is a true single component system, whether it’s in the liquid pre preg, the thickened, uh, the thickened putties that we sell, or even the hand lamination and effusion resin. It’s doped with a, a variety of different food initiators and packages based on the type of light that’s [00:07:00] being, uh, used to, to cure it. But it will truly stay dormant until it’s exposed to UV light. And so we’ve been able to formulate systems over the last 40 years of our company’s history that provide an incredibly long shelf life. Don’t prematurely gel, don’t prematurely, uh, you know, erode in the packaging, all those  Allen Hall: things.  Bret Tollgaard: Exactly. Like we’ve been at this for a really long time. We’ve been able to do literally decades of r and d to develop out systems. Uh, and that’s why we’ve been able to come to this market with some materials that truly just haven’t been able to be seen, uh, delivered and installed and cured the way that we can do it. Allen Hall: Well, I think that’s a huge thing, the, the shelf life.  Bret Tollgaard: Mm-hmm.  Allen Hall: You talk to a lot of. Operators, ISPs that buy materials that do have an expiration date or they gotta keep in a freezer and all those little handling things.  Bret Tollgaard: Yep.  Allen Hall: Sunrise gets rid of all of that. And because how many times have you heard of an is SP saying, oh, we had a throwaway material at the end of the season because it expired. Bret Tollgaard: Oh, tremendously  Allen Hall: amount of,

The Uptime Wind Energy Podcast brought to you by Strike Tape, protecting thousands of wind turbines from lightning damage worldwide. Visit strike tape.com. And now your hosts.  Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host, Allen Hall. I’m here with Matthew Stead, Rosemary Barnes and Yolanda Padron. And the UK is really gearing up for offshore wind and they’re making some really smart moves and. One of them is, uh, the change in tariffs. So the British offshore wind manufacturers have been fighting really an uphill battle for a long time and for years. The companies that build turbines and components in the UK have faced import tariffs on the materials needed most, which tends to be steels like steel. Uh, cables, specialized parts from overseas all carried a tariff with it. Well, now the federal government has acted to [00:01:00] remove those tariffs on offshore wind equipment. The move is expected to save UK manufacturers tens of millions of pounds every year. And for an industry trying to cut costs and scale up that kind of relief could make the difference between winning. Losing contracts, and I’m surprised the UK has waited this long and I think other countries have the same problem. Obviously the US is taring the heck out of everything at the minute, but uh, a lot of European countries do put tariffs on the raw materials and the components that are used to make wind turbines. That’s not a smart long term move if you’re trying to deploy. Gigawatts of offshore wind.  Matthew Stead: Well, I, I think, uh, the recent events in the world show that energy security and not importing energy is a wonderful thing. And so this completely aligns with that, um, that objective. So I think that’s why we all agree with you, Alan. Allen Hall: Well do, is there a, a. A threshold here where other countries start to do it [00:02:00] and for whatever reason there’s, there’s tends to be tariffs on energy in all forms of it. Right. And there and on steel in particular, that seems to be a big area of concern. Are we gonna start to see some of those come down just to lower the cost of wind turbines and to deploy the middle of the water? ’cause there is a lot of steel in an offshore wind turbine.  Matthew Stead: It’s been like China. I mean China has, you know, a lot of clean energy, low cost energy and it is to their advantage. So I, I think it’s a entirely logical approach and I would’ve thought it’s, if you’re a good on policy, you would definitely be looking at this. Allen Hall: Is this has been a concern of the UK steel industry, which has been diminishing over the years? Uh, so it’s always been a pain point with the uk. They’ve been trying to stand up their own steel industry and forever they had a big steel industry In the uk you think of all the. The steel that was built from late 18 hundreds all the way up to the 1980s and nineties. Uh, but it does sound like you, you gotta pick and choose your battles here. And maybe the UK has [00:03:00] finally said, okay, the, the steel battle is a separate issue within offshore wind, and maybe we gotta do something different.  Matthew Stead: I mean, I think Australia did the same thing ages ago. I mean, we had a car, car industry and you know, we just didn’t have the scale. So, you know, Australia’s picking its battles and um, yeah, I mean, you can’t be good at everything, so you know why not. Uh, get the, the lower cost energy and um, deal with it that way.  Rosemary Barnes: Australia has actually just announced, you know how Australia’s got the policy to support clean energy technology manufacturing in Australia. And they started with, um, solar panels and then they’ve also got something related to battery cells. Well, they just announced wind turbine tower manufacturing, um, which is very simple. The reason why Australia doesn’t have, um, wind turbine tower manufacturing anymore. Is just because we can’t compete on price with Asia, um, in general and China specifically. It’s interesting now to be like, okay, let’s support Australian [00:04:00]manufacturing of wind turbine towers when like there’s no technological barrier. It’s pure cost, cost issues. I would really love to see the Australian government supporting some of the new manufacturing methods and you know, like we’ve seen that Fortescue has invested in. Um, in Ena Lift, the Spanish, Spanish company, um, ESCU has, has bought their tower manufacturing. Um, it’s, it’s like modular, advanced thing that’s gonna work well for remote areas. Otherwise it’s just like, pay a bunch of money so that we can make towers more expensively, but we can sell them at a competitive rate with the Chinese. And I don’t know, to me that’s not very strategic. I always prefer we support the next, the next thing.  Allen Hall: Whatever happened to spiral welding and making towers on site. I think that died about a year or two ago because they were trying it here in the United States and about building ’em at the wind farm. But it sounded like just setting it up to [00:05:00] build the spiral mechanism, the, the cold, uh, forming plus all the welding on top of it. It got to be so expensive to install on site that it was just easier to, to build a central location, which I think they were going for. I’m not even sure that in today’s world, because of the advanced technology in the existing way of manufacturing is so good and inexpensive that it makes any sense to try anything else. It just seems like it’s, there’s just stamping out parts right now.  Rosemary Barnes: Oh, no. I mean, we definitely need new, new methods because we’re really constrained on how tall towers can get if you just wanna make a steel cylinder and ship it out in, you know, whole pieces, like whole cross sections and. Um, put them together vertically. That’s you. You know, like we’ve, we’ve gotten about as tall as we’re gonna get for that because if you want to go any taller, you’re gonna have to start massively increasing the thickness of the tower to make it stiffen up. And that just means way more steel to keep material costs reasonable. You need to increase the diameter, um, beyond [00:06:00] what you can transport on the road. Um, but I think that it’s like the, the, the problem is definitely real and well established, but it’s like with many other. Problems. You know when you start thinking, okay, we’ve got a solution to this problem at that time, there aren’t other solutions, so you’re sure that you know you’re gonna win. And so spiral welding was one of the early ones. Oh, we can fix this problem, but. While they’re developing that and trying to get the capabilities where it needs to be, the cost down, you’ve got a dozen other competing ways that you could solve that problem. And they include like, um, some manufacturers, I think Vestus is one. They’re cutting longitudinally. And so instead of, um, shipping out towers in a single cross section, it’ll be like four. And then they’re bolted together on site. Um, and then Concrete Towers is another one. The Naber Lift, um, thing that I mentioned.  Matthew Stead: Wooden towers.  Rosemary Barnes: Yeah, wooden Wooden towers is, uh, another one I’ve covered, uh, [00:07:00] on my YouTube channel. Matthew Stead: They really should make them out of carbon fiber, shouldn’t they?  Rosemary Barnes: Well, I have, it’s not, it’s You’re saying that as a, as a crazy thing. It’s not, it’s not such a crazy thing. And I have, I have, I have looked into it. You wouldn’t do it outta carbon fiber. You’d do it outta glass. Um, there’s a lot of. There’s a lot of benefits to it, and I actually do believe that we might eventually see like 3D printed glass, um, towers. Allen Hall: No.  Rosemary Barnes: Now we’re just getting into our standard. I, I believe the future might look different to the, to the present day, and Alan never thinks that anything’s ever gonna change.  Matthew Stead: I would’ve. 3D uh, printed concrete towers would have some logic.  Rosemary Barnes: There’s been pilots of 3D printed concrete, concrete towers. I’m, I’m pretty sure GE had a, um, a project on that and there might have been somebody else that did, took it a bit further. It’s all possible. It’s also like concrete towers are, are good, but it is local. Like it depends on having the right materials around locally. ’cause you don’t want to have to transport Hess of. Concrete and water to site. Um, [00:08:00] so yeah, anyway, the point is that like, just because you’ve identified a real problem and you’ve got a solution to it, if you are gonna take five or 10 years to develop your technology and get it to the right price point, you are not gonna be the only, the only solution anymore. So people often like massively overestimate how valuable their idea is. Um, and by the time that it’s ready, it’s not the best solution anymore. So I think like the lesson from that is to just. You need to just move really, really fast and keep your peripheral vision available to see what other technologies are developing in tandem and know when, when to pull the pin. If you are no longer, you no longer have a path
