Welcome to Uptime Spotlight, shining Light on Wind Energy’s brightest innovators. This is the Progress Powering Tomorrow.

Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host, Alan Hall in the Queen city of Charlotte, North Carolina. Joel Saxon’s up in Wisconsin, and Yolanda Padron is down in Texas, and this is our yearly Thanksgiving edition. Thanks for joining us and, and on this episode we always like to look back at the year and, uh, say all we’re thankful for.

We’ve had a number of podcast guests on more than 50, I think total by the time we get to conferences and, uh, all the different places we’ve been over the past year. Joel, it does seem like it’s been a really interesting year. We’ve been able to watch. The changes in the wind industry this year via the eyes of [00:01:00]others.

Joel Saxum: Yeah. One of the things that’s really interesting to me when we have guests on is that we have them from a variety of parts of the wind industry sector. So we have ISPs, you know, people running things out in the field, making stuff happen. We’ve got high level, you know, like we have this, some CEOs on from different, uh, people that are really innovative and trying to get floating winged out there.

They have like on, we had choreo generation on, so we, so we have all different spectrums of left, right center, Europe, well us, you name it. Uh, new innovative technology. PhD smart people, uh, doing things. Um, also, it’s just a, it’s just a gamut, right? So we get to learn from everybody who has a different kind of view on what’s

Allen Hall: happening.

Yolanda, you’ve been in the midst of all this and have gone through a big transition joining us at Weather Guard, lightning Tech, and we’re very thankful for that, for sure. But over the last year, you’ve seen a lot of changes too, ’cause you’ve been in the seat of a blade engineer and a [00:02:00] large operator.

What do you think?

Yolanda Padron: Uh, something I am really thankful for this year is, and I think a lot of owner operators are, is just knowing what’s coming up. So there was a lot of chaos in the beginning before the big beautiful bill where everyone theorized on a lot of items. Um, and, and you were just kind of stuck in the middle of the court not really knowing which direction to go in, but.

Now we’re all thankful for, for what? It’s brought for the fact that everyone seems to be contributing a lot more, and at least we all know what direction we’re heading in or what the, what the rules are, the of the game are, so we can move accordingly.

Joel Saxum: Yeah. I got some clarity. Right. I think that, but that happened as well, like when we had the IRA bill come in.

Three, four years ago, it was the same thing. It was like, well, this bill’s here, and then you read through it. I mean, this was a little bit opposite, right? ’cause it was like, oh, these are all [00:03:00] great things. Right? Um, but there wasn’t clarity on it for like, what, six months until they finalized some of the.

Longer on some of the, some of the tax bills and what it would actually mean for the industry and those kind of things. So yeah, sorting this stuff out and what you’ve seen, you’re a hundred percent correct, Yolanda, like all the people we talked to around the industry. Again, specifically in the US because this affects the us but I guess, let me ca caveat that it does affect the global supply chain, not, you know what I mean?

Because it’s, it’s not just the, the US that it affects because of the consumption here. So, but what we have heard and seen from people is clarity, right? And we’re seeing a lot of people starting to shift strategy a little bit. Right now, especially we’re in budgeting season for next year, shifting strategy a little bit to actually get in front of, uh, I know like specifically blades, some people are boosting their blades, budgets, um, to get in front of the damages because now we have a, a new reality of how we need to operate our wind farms.

The offshore

Allen Hall: shift in the United States has really had a [00:04:00] dramatic impact. On the rest of the world. That was, uh, a little unexpected in the sense that the ramifications of it were broader, uh, just because of so much money going into offshore projects. As soon as they get pulled or canceled, you’ve have billions of dollars on the table at that point.

It really affects or seen it. Ecuador seen it. Anybody involved in offshore wind has been deeply affected. Siemens has seen it. GE has clearly seen it. Uh, that has. In my opinion, probably been the, the biggest impact. Not so much the big beautiful bill thing, but the, uh, ongoing effort to pull permits or to put stoppages on, on offshore wind has really done the industry some harm.

And honestly, Joel, I’m not sure that’s over. I think there’s still probably another year of the chaos there. Uh, whether that will get settled in the courts or where it’s gonna get settled at. I, I still don’t know. [00:05:00] But you’ve seen a big shift in the industry over in Europe too. You see some changes in offshore wind.

It’s not just the US that’s looking at it differently. Yeah. Globally. I think offshore wind

Joel Saxum: right now is in a reset mode where we, we went, go, go, go, go, go get as much in the water as we can for a while. And this is, I’m, I’m talking globally. Um. And then, and now we’re learning some lessons, right? So there’s some commercial lessons.

There’s a lot of technical lessons that we’re learning about how this industry works, right? The interesting part of that, the, the on or the offshore wind play here in the States. Here’s some numbers for it, right? So. It onshore wind. In the states, there’s about 160 gigawatts, plus or minus of, uh, deployed production out running, running, gunning, working, spinning all day long.

Um, and if you look at the offshore wind play in planned or under development, there’s 66 gigawatts of offshore wind, like it’s sitting there, right? And of that 66, about 12 of them are permitted. Like [00:06:00] are ready to go, but we’re still only at a couple hundred megawatts in the water actually producing.

Right. And, and I do want, say, this is what I wanna say. This is, I, I think that we’re taking a reset, we’re learning some things, but from, from my network, I’m seeing, I got a, a whole stack of pictures yesterday from, um, coastal offshore, Virginia Wind. They’ve, and they looked promising. They looked great. It was like a, it was a marshaling facility.

There was nelle stacked up, there was transition pieces ready to go. Like, so the industry is still moving forward. It’s just we’re we need to reset our feet, um, and, and then take a couple steps forward instead of those, the couple steps back,

Allen Hall: uh, and the industry itself, and then the employees have been dramatically reduced.

So there’s been a lot of people who we’ve known over the past year, they’ve been impacted by this. That are working in different positions, look or in different industries right now, uh, waiting for the wind industry to kind of settle itself [00:07:00] out to, to figure out what the next steps are That has been.

Horrible, in my opinion. Uh, uh because you’re losing so much talent, obviously. And when you, when you talk to the people in the wind industry, there’s like, oh, there’s a little bit of fat and we can always cut the fat. Yeah, yeah, yeah. But we’re, we’re down to the bone. We’re cutting muscle right now. We’re into some bones, some structure.

That is not what I anticipated to happen. But you do see the management of these companies being. Uh, very aggressive at the minute. Siemens is very aggressive. Vestas is very aggressive about their product line and, and getting availability way up. GE has made huge changes, pretty much closing LM wind power, uh, and uh, some things happening in South Carolina that we probably people don’t know about yet, but there’s so much happening behind these scenes that’s negative and we have to acknowledge it.

It’s not great. I worry about everybody that has been [00:08:00] laid off or is, is knows their job is gonna go away at the end of the year. I struggle with it all the time and I, I think a lot in the wind industry do. But there’s not a lot to do about it besides say, Hey, uh, we’ve gone through this a couple of times.

Wind has never been bountiful for 50 years. It’s bountiful for about 10, then it’s down for about five and it comes back for 10. It’s that ebb and flow, but you just hate to be involved with that. It’s particularly engineering ’cause this industry needs engineering right

Joel Saxum: now. All of us on this podcast here have been affected by ups and downs in the industry at some point in time in our life, in in major ways.

I guess one of the positive things I have seen that from an operator standpoint, and not as much at the latter half of this year, but at the beginning half of this year is when some of these OEMs were making cuts. There was a lot of people that landed at operators and asset owners that were huge assets to them.

They walked in the door with. Reams of knowledge about how, [00:09:00] you know, how a ge turbine works or how the back office process of this works and they’re able to help these operators. So some of that is good. Um, you get some people spread around in the industry and some knowledge bases spread around. But man, it’s really hard to watch.

Um, your friends, your colleagues, even people that you, that you don’t know personally just pop up on LinkedIn, um, or wherever. And. That they’ve, they’re, they’re looking for work again.

Allen Hall: Yolanda, how do you look at 2026 then, knowing what’s just happened in 2025? Is there some hope coming? Is there a rainbow in the future?

Yolanda Padron: I think there’s a rainbow in the future. You know, I, I think a lot of the decisions were made months ago before a lot of people realized that the invaluable, how invaluable some of that information in people’s heads is. Uh, particularly, I mean, I know we’ve all talked about the fact that we’re all engineers and so we, we have a bit of bias that way.

Right. But, uh, [00:10:00] just all of the knowledge that comes in from the field, from looking at those assets, from talking to other engineers now, which is what, what we’re seeing more and more of, uh, I think, I mean. So there’s going to have to be innovation, right? Because of how, how lean everybody is and, and there’s going to have to be a lot more collaboration.

So hopefully there, there should be some, some good news coming to people. I think we, we need it a little

Joel Saxum: bit. You know, to, to, to pair on with what you’re saying there, Yolanda, like, this is a time right now for innovation and collaboration. Collaboration, right. I want to touch on that word because that is something that we, we talk about all the time on the podcast, but you also see the broader industry talking about it since I’ve been in it, right.

Since I think I came in the wind industry, like 2019. Um, you hear a lot of, uh, collaboration, collaboration, collaboration. But those were like, they were [00:11:00] fun, like hot air words, like oh yeah, but then nobody’s really doing anything. Um, but I think that we will start to see more of that. Alan, you and I say this a lot, like at the end of the day, once, once the turbines are in the ground as an asset owner, you guys are not competing anymore.

There’s no competition. You’re competing for, for green space when you’re trying to get the best wind resource. I get that. Um, but I mean, in the central part of the United States, you’re not really competing. There’s a lot of hills out there to stick a turbine on. Uh, but once they’re, once they are spinning.

Everybody’s in the same boat. We just wanna keep these things up. We wanna keep the grid energized, we wanna do well for renewable energy and, um, that collaboration piece, I, I, I would like to see more and more of that in 2026. And I know from, from our chairs here, we will continue to push on that as well.

Yolanda Padron: Yeah. And just so many different operators, I mean sure they can see themselves as, as being one against the other. Right. But. When you talk [00:12:00] to these people and it, I think people in the past, they’ve made the, the mistake of just being a little bit siloed. And so if you’re just looking at your assets and you’re just looking at what your OEM is telling you of, oh, these problems are new and unique to you, which I’m sure a lot of people hearing us have heard that.

You can stay just kind of in that zone of, oh no, I, I have this big problem that there’s no other way to solve it except for what some people are telling me or not telling me, and I’m just going to have to pay so much money to get it done and take the losses from generation. Uh, but there’s so many people in the industry that have a hundred percent seen the issues you’ve seen.

Right. So it’s, it’s really, really important to just talk to these people, you know? I mean, just. Just have a, a simple conversation. And I think some of the issue might be that some people don’t know [00:13:00] how to get that conversation started, right? And so just, just reach out to people, someone in the same position as you go to Wilma, you know, just talk to the person next to you.

Joel Saxum: I mean, like I said about visibility, like we’re here too. Like the, the three of us are sitting here. We’ve got our. We’re always monitoring LinkedIn and our emails like if you, if you have a problem, we, we had one this morning where I, Alan, you got a message from someone, I got a message from someone that was like, Hey, we’ve got this root bolt issue.

Can you help us with it? We’re like, Hey, we know two companies that can, let’s just connect them up and, and make that conversation happen. So we’re happy to do the same thing. Um, if, if you have an issue, we have a, a

Allen Hall: broad reach and use us as Joel has mentioned a thousand times on the podcast. If you don’t know where a technology lies or where a person is that you need to reach out to, you need to go to the Uptime podcast.

You can search it on YouTube and probably get an answer, or just reach us on LinkedIn. We’re all willing [00:14:00] to give you advice or help or get you in the right direction. We’ve done it all year and we’ve done it for years. Not everybody takes us up on that opportunity. It’s free. We’re just trying to make this world just a tiny bit better.

Yolanda Padron: No one has the time or the money right now to reinvent the wheel, right? So I mean, it just doesn’t make sense to not collaborate.

Allen Hall: I think we should discuss what will happen to all the people that have left wind this past year willingly or unwillingly. And what that means for the industry, in my opinion.

Now there is more knowledge than ever walking on the streets and probably doesn’t have an NDA to tie them up. ’cause it’s been long enough that the industry hasn’t tapped into, the operators have not grabbed hold of the people who designed the blade that, uh, manufactured the blade that looked at. The LEP solutions that looked at all the bearings and all the different gear boxes that they evaluated and were involved in the testing of those [00:15:00] things.

Those people are available right now and a little bit of LinkedIn shopping would give you access to, uh, really invaluable wealth of information that will make your operations work better, and you may have to be willing to pay for it a little bit. But to tap into it would save you months and months and months of time and effort and, uh, limit having to add to your engineering staff because they will work as consultants.

It does seem like there’s an opportunity that maybe the operators haven’t really thought about all that much because they haven’t seen too much of it happening yet. Occasionally see the, the wise old operators being smart about this, they’ve been through these loops before and are taking advantage of it.

Don’t you see? That’s like 2026 is is is the year of the consultant. I a hundred percent

Joel Saxum: agree with you, Alan. Um, I saw a TEDx talk oh, years ago actually now. Uh, but it was about the, what the future of worker looks like, the future of [00:16:00] work and the future of work at that time for those people giving that TEDx talk was workers on tap.

Basically consultants, right? Because you have subject matter experts that are really good at this one thing, and instead of just being that one thing good for just this one company, they’re pulling back and going, I can do this, this, this, and this for all these companies. So we have, um, we have a lot of those in the network and we’re starting to see more and more of them pop up.

Um, at the same time, I think I’ve seen a couple of groups of them pop up where, uh, you didn’t have. When I look at ISPs, um, I’m always kind of like, oh man, they could do this a little bit better. They could do this a little bit better. And I, I recently heard of an ISP popping up that was a bunch of these like consultant types that got together and we’re like, you know what?

We have all this knowledge of all these things. Why not make this a, a company that we can all benefit from? Um, and we can change the way some things are done in the wind industry and do it a little bit better, uh, a little bit more efficiently.

Allen Hall: Does that change the way we think about technicians also. [00:17:00] We had the Danish Wind Power Academy on the podcast a couple of months ago talking about training and specific training for technicians and engineers for that matter on the turbines that are at their sites and how much productivity gain they’re getting from that.

And we’ve recently talked about how do I get a 10% improvement? Where does that 10% lie? Where is that? And a lot of times we get offered the 1%, the half a percent improvement, the 10% lies in the people. If you know who to ask and you get your people spooled upright, you can make multiple percentage point changes in your operation, which improves your revenue.

But I think that’s been left on the table for a long time because we’ve been in build, build, build. And now that we’re into operate, operate, operate. Do you see that shift happening? Do you see O operators starting to think about that a little bit that maybe I should train up my technicians on this?

Intercon turbine

Joel Saxum: that they’re not familiar with. In my [00:18:00] opinion, I think that’s gonna be a 2027 reality. Because we’re seeing this, your, your right now what? You know we have this cliff coming where we’re gonna see in, in the face of the current regulations in the US where you’re gonna see the. Development kind of slow, big time.

And when that happens, then you can see the focus start to switch onto the operating assets. So I don’t think that’s a 26 thing, I think that’s a 27 thing. But the smart operators, I believe would be trying to take some of that, take control of some of that stuff. Right. Well we see this with the people that we know that do things well.

Uh, the CRS team at EDF with their third party services and sala, Ken Lee, Yale, Matta, and those guys over there. They’re doing a, I don’t wanna lose any other names here, Trevor Engel. Like, I wanna make sure I get a Tyler. They’re all superstars, they’re fantastic. But what they’re doing is, is is they’re taking, they’re seeing what the future looks like and they’re taking control.

I think you’ll see, you’ll, you’ll see an optimization. Um, companies that are investing in their technicians to train [00:19:00] them are going to start getting a lion’s share of the work, because this time of, oh, warm bodies, I think is, is they’re still gonna be there, right? But I think that that’s gonna hopefully become less and less.

Allen Hall: Yolanda, I want to focus on the OEM in 2025, late 2025, and moving into 2026 and how they deal with the developers. Are you thinking that they’re going to basically keep the same model where a lot of developers are, uh, picking up the full service agreements or not being offered a turbine without a full service agreement?

Will that continue or do you see operators realize that they probably don’t need the OEM and the historical model has been OEMs manufacture products and provide manuals in the operations people and developers read the manuals and run the turbine and only call over to the OEM when they need really severe help.

Which way are we gonna go?

Yolanda Padron: I think on the short term, it’ll still be very FSA focused, in my opinion, [00:20:00] mainly because a lot of these operators didn’t necessarily build out their teams, or didn’t have the, the business case wasn’t there, the business model wasn’t there. Right. To build out their internal teams to be able to, to do the maintenance on these wind turbines as much as an OEM does.

Uh. However, I do think that now, as opposed to 10 years ago when some of these contracts started, they have noticed that there’s, there’s so many big things that the OEN missed or, or just, you know, worked around, uh, that really has affected the lifetime of some of these blades, some of these turbines. So I think the shift is definitely happening.

Uh, you mentioned it with EDF NextEra, how, how they’re at a perfect spot to already be there. Uh, but I think at least in the US for some of these operators that are a lot [00:21:00] more FSA focused, the shift might take a couple of years, but it’s, it surely seems to be moving in that direction.

Joel Saxum: So here’s a question for you, Ilana, on that, on that same line of thinking.

If we, regulation wise, are looking to see a slow down in development, that would mean to me that the OEMs are gonna be clamoring for sales over the next few years. Does that give more power to the operators that are actually gonna be buying turbines in their TSA negotiations?

Yolanda Padron: I think it should, right. I mean, the.

If they, if they still want to continue developing some of these, it and everyone is fighting, you know, all of these big OEMs are fighting for the same contracts. There’s, there’s a lot more kind of purchase power there from, from the operators to be able [00:22:00] to, to, you know, negotiate some of these deals better.

Stay away from the cookie cutter. TSA. That the OEMs might supply that are very, very shifted towards the OEM mindset.

Joel Saxum: You, you’re, you’re spot on there. And if I was a developer right now, I’d be watching quarterly reports and 10 k filings and stuff at these operators to make sure, or to see when to pounce on a, on a, a turbine order, because I would wait to see when in, in the past it’s been like, Hey, if we’re, it doesn’t matter who you are, OEM, it has been like we’re at capacity and we have.

Demand coming in. So we can pick and choose. Like if you don’t buy these turbines on our contract, we’ll just go to the next guy in line. They’ll buy ’em. But now if the freeboard between manufacturing and demand starts to keep having a larger delta, well then the operators will be able to go, well, if you don’t sell it to me, you’re not, there isn’t another guy behind me.

So now you have to bend to what I want. And all the [00:23:00] lessons that I’ve learned in my TSA negotiations over the last 20 years.

Yolanda Padron: Something relating to Alan’s point earlier, something that I think would be really, really interesting to see would be some of these developers and EPC teams looking towards some of those contract external contractor consultants that have been in the field that know exactly where the issues lie.

To be able to turn that information into something valuable for an operating project that. Now we know has to operate as long as possible,

Allen Hall: right? Without repower, I think two things need to happen simultaneously, and we will see if they’ll play out this way. OEMs need to focus on the quality of the product being delivered, and that will sustain a 20 year lifetime with minimal maintenance.

Operators need to be more informed about how a turbine actually operates and the details of that technology so they can manage it themselves. Those two things. Are [00:24:00] almost inevitable in every industry. You see the same thing play out. There’s only two airplane companies, right? There’s Boeing and Airbus.

They’re in the automobile world. There’s, it gets fewer and fewer every year until there’s a new technology leap. Wind is not gonna be any different, and I hope that happens. OEMs can make a really quality product. The question is, they’ve been so busy developing. The next turbine, the next turbine, the next turbine.

That have they lost the magic of making a very, very reliable turbine? They’ll tell you, no, we know how to do it. Uh, but as Rosemary has pointed out numerous times, when you lose all your engineering talent, it gets hard to make that turbine very robust and resilient. That’s gonna be the challenge. And if the OEMs are focused on.

TSAs it should be, but the full service agreements and taking care of that and managing all the people that are involved with that, it just sucks the life out of the OEMs, I think, in terms of offering the next great product. [00:25:00]Someone showed me the next GE

Joel Saxum: one five. Oh, I would love to see it. Do you believe that?

Okay, so I, we’ll shift gears from oe, uh, wind turbine OEMs to blade manufacturers. LM closing down shops, losing jobs, uh, TPI bankruptcy, uh, 99% of their market cap eroding in a year is there and, and, and the want for higher quality, better blades that are gonna last. Is there space, do you think there’s space for a, a blade manufacturer to come out of nowhere, or is there just someone’s gonna have to scoop some of these factories up and and optimize them, or what do you think the future looks like for blade

Allen Hall: manufacturers?

The future is gonna be vertically integrated, and you see it in different industries at the moment where they’re bringing in technology or manufacturing that would have typically been outsourced in the two thousands. They’re bringing it back underneath their roofs. They’re buying those companies that were vendors to them for years.

The reason they’re doing that is they [00:26:00] can remove all the operational overhead. And minimize their cost to manufacture that product. But at the same time, they can have really direct oversight of the quality. And as we have seen in other industries, when you outsource a critical component, be it gear, boxes, bearings, blades, fall into that category, those are the critical items for any wind turbine.

When you outsource those items and rely upon, uh, uh, companies that you don’t have direct control over, or not watching day to day, it can go awry. Management knows it, and at some point they’re willing to accept that risk. They know that the cost is right. I gotta build this, uh, turbine. I know I’m working three generations ahead, so it’s okay, I’ll, I’ll live with this for the time being, but at some point, all the staff in the OEMs needs to know what the quality component is.

Is it being delivered on time? Do I have issues out in the field with it? Do I keep this supply chain? Do I, and do I build this in house blades? [00:27:00] I think eventually. Like they were years ago, were built in-house. Uh, but as they grew too quickly, I think everybody will agree to that

Joel Saxum: capacity. Yeah,

Allen Hall: right. They started grabbing other factories that they didn’t know a lot about, but it gave them capacity and ability able to make sales.

Now they’re living with the repercussions of that. I think Siemens is the obvious one, but they’re not the only one. GE has lived through something very similar, so, uh, vertical integration is going to be the future. Before we wrap the episode, we should talk about what we’re thankful for for this year, 2025.

So much has happened. We were in Australia in February, weather guard moved in April to North Carolina. We moved houses and people, and the whole organization moved from Massachusetts and North Carolina. Joel got married. Yolanda got married. We’ve been all over the world, honestly. Uh, we’ve traveled a great deal and we’re thankful for everybody that we’ve met this year, and that’s one of the pleasures of doing this podcast is I just [00:28:00] get to meet new people that are very interesting, uh, and, uh.

Talk, like, what’s going on? What are you thinking? What’s happening? It just feels like we’re all connected in this weird way via this podcast, and I, I, I’m really thankful for that and my always were saying Thanks. I will go through my list. I’m thankful for my mom. I’m thankful for my wife Valerie, who pretty much runs Weather Guard, lightning Tech, and Claire, who is my daughter who does the podcast and has been the producer, she graduated this year from Boston College.

With honors that happened this year. So I’m very thankful that she was able to do that. And my son Adam, who’s earning his doctorate degree out in San Diego, always thankful for him ’cause he’s a tremendous help to us. And on the engineering side, I’m thankful to everybody we have with us this year. We brought Yolanda on, so we’re obviously thankful that, uh, she was able to join us.

Of course, Joel Joel’s been here a couple of years now and helping us on sales and talking to everybody [00:29:00] in the world. We’re super thankful for Joel and one of the people we don’t tell behind the who’s behind the scenes on our side is our, our, uh, manufacturing person, Tammy, um, and Leslie. They have done a tremendous job for us over the years.

They don’t get a lot of accolades on the podcast, but people who receive our strike tape product, they have touched. Tammy and Leslie have touched, uh, Tammy moved down with us to North Carolina and we’re extremely grateful that she was able to do that. Another person behind the scenes for us is Diane stressing.

She does her uptime tech news newsletter. So the high quality content doesn’t come from me, it comes from Diane ’cause she can write and she’s an excellent newsletter writer. She helps with a ton of our content. She’s behind the scenes and there’s a lot of people at, at, uh, weather, car Lightning Tech that are kind of behind the scenes.

You don’t get to see all the time, but when you do get an email about uptime, tech news is coming from Diane. So we’re super grateful for her. We’ve been blessed this year. We [00:30:00] really have. We’ve brought on a lot of new friends and, uh, podcast has grown. Everything has done well this year, so we’re super happy.

Joel, what are you thankful for?

Joel Saxum: I would start it the same way. Uh, my, my new. Sorry, my new wife as of last May, Kayla, she is the, the glue that holds me together, uh, in our household together, in this kind of crazy world that we’re in, of the ups and downs and the travels and the moving and grooving. Um, she keeps, she keeps me grounded.

She keeps our family grounded. So, um, uh, I, I don’t think I can thank her enough. Uh, and you know, with that being said, we are always traveling, right? We’re, we’re here, we’re there. We’re. All around the world, and I am thankful for that. Um, I’m thankful for the people that we meet while we get to travel, the cultures and the, the experiences and the people that want to share with us and the knowledge gained from, uh, the conversations, whether it be in a conference room or over a beer.[00:31:00]

Um, uh, the, the people that we have, uh, grown into this uptime network and, um, I know like my personal network from the past and of course everybody that will come in the future. I think that’s where, you know, the, the, if you know me, you know that I’m very much an extrovert, uh, talking with people and, and getting those conversations gives me energy.

Um, and I like to give that back as much as I can. So the, all of the people that I’ve run into over the, over the past year that have allowed me to monologue at them. Thank you. Sorry. Apologies. Um, but, uh, yeah, I mean, it’s, it’s hard to. I think this, this is a, this is always why Thanksgiving is like a six hour long thing in the United States, eight hour long thing.

You have dinner at three and you hang out with your friends and family until 10, 11:00 PM because it gives you time to reflect on, um, the things that are awesome in life. Right? And we get bogged down sometimes in our, you know, in the United States. We are [00:32:00] work, work, work, work works. First kind of society.

It’s the culture here. So we get bogged down sometimes in the, you know, we’re in the wind industry right now and it’s not always. Um, you know, roses and sunshine, uh, but ha having those other people around that are kind of like in the trenches with you, that’s really one thing I’m thankful for. ’cause it, it’s, it’s bright spots, right?

I love getting the random phone calls throughout the day of someone sharing a piece of information or just asking how you’re doing or connecting like that. So, um, that, that would be the, the thing I’m most thankful for, and it puts it into perspective here, to a me up home in Wisconsin, or my, my not home.

Home is Austin, but my original hometown of northern Wisconsin, and I’ve got to see. Quite a few of my, my high school buddies are, yeah, elementary school buddies even for that matter over the last couple weeks. And, um, that really always brings me back to, to a bit of grounding and puts, puts life in perspective.

So, uh, I’m really appreciative for that as well. Yolanda, newly married as well, and welcome to the club.

Yolanda Padron: Thank [00:33:00] you. Yeah, I’m really, really thankful for, for Manuel, my husband, uh, really. Really happy for our new little family. Uh, really thankful for my sisters, Yvonne and Carla and my parents. Um, my friends who I like to think of as my chosen family, especially, you know, here in Austin and then, and in El Paso.

Uh, really, really thankful for, for the extended family and for, for weather card for, for this lovely opportunity to just. Learned so much. I know it’s only been almost two months, but I’ve, I’ve just learned so much of just talking to everybody in the industry and learning so much about what’s going on everywhere and just getting this, this whole new outlook on, on what the future holds and, and what exactly has happened and technology wise, and I’m thankful for [00:34:00] this year and how.

How exciting everything’s going to be. So, yeah, thankful for you guys.

Allen Hall: And we don’t wanna forget Rosemary and Phil, uh, they’ve been a big part of 2025. They’ve worked really hard behind the scenes and, uh, I appreciate everything they’ve done for the podcast and everything they’re doing for. Us as a company and us as people.

Welcome to Uptime Spotlight, shining Light on Wind. 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.

Does Sharia Law pose an actual threat to Americans?  Are we on a path to chopping off the hands of shoplifters? Passing laws that concern what people can and cannot eat? Polygamy?  Forcing women to wear the hijab?

Maybe.

Or maybe this congressman is a loudmouth asshole whose constituents are morons.

Carlson’s about-face on Trump is huge, as it signals that public intellectuals who wish to be taken seriously at this point cannot support the president, as his mental condition deteriorates and his criminality becomes ever more brazen.
