Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host, Allen Hall, and I’m here with Joel Saxum up in the great state of Wisconsin.

Phil Totaro is in California, and Rosemary Barnes is here, but she’s in a vehicle in Australia somewhere. But there has been a tremendous amount of news over the last couple of days, and I think we should talk about some of them. Uh, I guess it’s, it’s a where the group would like to go. This week, guys, you know, we’ve been talking about the administration for the last several weeks and about administration out, uh, the latest is with, uh, the administration in [00:01:00]court about Empire Wind.

Do you want to even talk about that stuff this week or do you wanna move on to some things? A little happier? Let’s do happier. Alan. I think we should, we need some different news. I feel the same way, Joel, you know, uh, when this podcast comes out, everybody’s, everybody’s gonna be in Husam, Germany having a great time, uh, talking wind energy, particularly in Europe.

And it sounds like that event is gonna be bonkers from what I can tell on LinkedIn.

Joel Saxum: Yeah. The, I mean, HU is only second to Hamburg right in, in Germany there. Everybody that I go, they enjoy it. Husam is like the, the. Correct me if I’m wrong, Phil, but I think it was like the first place they had onshore wind in a big way in Germany.

Phil Totaro: Yes. So it’s vestus, um, put up a factory there, uh, and was selling wind turbines to farmers. It’s also where they used to do, the reason that it’s there is they used to do an agriculture. Um, event and then they used to invite some of the wind guys. This is going back to like the, you know, late eighties, early nineties.

[00:02:00] They used to invite the wind guys, or the wind guys used to show up to try and sell turbines at this agriculture event. The amount of people interested in wind got to such an extent that they started doing a separate wind event. Um, and it got. Before they started the separation with the, the Wind Energy Hamburg, um, event, they, uh, that got to a point, I mean, I remember being there in what, 2015 or 2016 when it had to have been.

30,000 people in a field in Huso. You know, I, my best memory of it, I think was when, uh, well it was eon at the time, but, uh, they had a guy running around, passing out hot dogs. And I had a eon hotdog.

Joel Saxum: Phil, I wanted to share with you. This was a Deutsche Wind Technique show, San Antonio a CP. They had margaritas with the Deutsche Wind Technique logo in the margarita, like foam, the foam on top of the margarita once, and they were passing those out at an event.

I thought that was spot on.

Phil Totaro: The hot dogs [00:03:00] are not branded in any way, although that would’ve been a good idea to like, you know, stamp the button or something.

Joel Saxum: What, how do we do that for weather guy to the next event? How we have like lightning bolt popsicles or something? Oh,

Allen Hall: I’m sure that can happen.

Lightning bolt cookies, maybe. Well, cookies. We all love cookies. Who doesn’t love good chocolate chip cookie? You know who told me about Husam first was Lars Benson and at AC 8 83 and he described it as just a. Complete craziness in the middle of a field. You had to go rent a house to stay there. But it was a heck of a lot of fun.

And I thought, well, if Lars is having fun, it must be really fun. ’cause

Phil Totaro: Lars likes to have fun. I used to have to take the train on a daily basis from Hamburg because there was no way you could even get a house or a hotel. It was so busy, uh, in, in that little town. Um. So, yeah, it was, it was quite an experience and they’ve eventually worked out all the logistics.

’cause they used to not even have like, shuttle service from the train station to the event. Um, but there were so many people that demanded it that they started [00:04:00] adding these kind of amenities, uh, which, which was nice.

Joel Saxum: I did wanna share this one. Uh, you mentioned, uh, Lars Benton, Alan, um, Lars and the team over at a CA 83.

Recently Lars stepped, stepped into the executive chair and handed over the. The main keys to the organization to Yannick, so Yannick Benson, the new CEO at a C 83. So a little bit of a management change up there in Canada. That company growing, selling spare parts, doing blade work, doing service work, all kinds of good things.

Allen Hall: Yeah, if you need spare parts, you better be calling Yannick. It’s, it’s spare parts are hard to get at the moment and I know Yannick and Lars have connections and places you can’t get to, so it’s a good place to reach out to AC 8 83. Just in time for a husam. The new PES win magazine is out. This thing is heavy.

It’s full of great articles and I’ve been thumbing through it, uh, recognizing a lot of people that I know in the magazine and that’s awesome. Uh, but Joel pointed out that, uh, Amond Costa Rego [00:05:00] is in it from Earth Wind. And, and Arthur Wind is, we’ve, we talked to Armando a couple of months ago, Joel, down in Nashville.

That seems like an eternity ago.

Joel Saxum: Yeah, I’ll tell you what, uh, Armando night chat quite regularly. We’re on the WhatsApp telling jokes, talking family stuff off and on, and that man is everywhere. Uh, I talked to him last week. He was in Mexico. He was in Chile. He was in Argentina at all the wind events. He’s got wind, uh, power Brazil coming up.

I know he’s doing a big thing with the ARS wind team down there for that. He was at a CP Nashville. He, for OMS, he was at a CP in Phoenix. He’s like every event everywhere. He’s there every, no matter what Europe. South America, it doesn’t matter. Um, but yeah, the article they’re showcasing, of course what Earth Wind does is as a blade consultant, they’re top tier.

They’ve got a large team. They have a lot of experience inside the factories, um, auditing blades as they’re coming off the lines. Internal inspections, external inspections, blade expertise. Uh, they’ve got their [00:06:00] own platform, ARS Next, which is kind of, um, it’s, it’s, it’s solid, right? It’s good. Yeah. It’s good stuff for, uh, validating repairers realtime feedback.

Um, I know they got some little AI engines for chat bots and stuff in there. They’re doing some, some really cool things. Um, so, and if you haven’t, if you’ve met r Armando, you’ve probably also met our good friend Rodolfo, uh, who is, who is a. A strong right hand for Armando and uh, that team down there is, um, they’re doing big things in Brazil.

Allen Hall: Yeah, a lot of great things happening at Earth, wind, and they are worldwide. If you need help with inspections or technology, or blade management or turbine management. Earth Wind is definitely a place to check out, and you also need to check out PES Wind, so if you haven’t downloaded your copy, you can go to PS wind.com and download your copy today.

As Wind Energy Professionals, staying informed is crucial, and let’s face it difficult. That’s why the Uptime podcast recommends PES Wind Magazine. PES [00:07:00] Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future. Whether you’re an industry veteran or new to wind, PES Wind has the high quality content you need.

Don’t miss out. Visit PES wind.com today. You wanna talk about cables? You wanna talk about storage batteries? I think we should do the, the cables and batteries. You pick the order.

Rosemary Barnes: Yeah. I mean, they relate. I’m sure one will flow into the other.

Allen Hall: Well, if more things could not go wrong, forested at the minute, and I know, uh, we’re watching Orid all the time, watching the stock price, watching them get their feet back underneath of them.

Stead has a lot of projects still going on today, and I think everybody forgets about that, that they’re a worldwide company and they’re doing great things all over. Uh, but they had a setback in Taiwan, so an export cable was damaged at the greater Chenwa two B offshore wind project, uh, which is going to push back the completion of that project.

To sometime in [00:08:00] late 2026, it’s about a 300 million Danish kroner hit on the, on the revenue chain, uh, which is about $50 million. It’s not a huge deal, but when I read this article, Joel, the first thing I was, I thought about you saying that on offshore, the biggest risk isn’t the actual turbines, it’s the cable, and there’s a lot of damaged cable as they’re deploying ’em.

What likely happened here in Taiwan?

Joel Saxum: Well, it’s an in, I think the first off, it’s interesting that they’re taking the hit. I, I don’t, I think that’s the, the headline, but that’s gotta be an insurance policy that’s covering this. There’s no way that Ted’s covering $50 million ’cause they, ’cause this should be under built, under construction policy.

So onto the technical side of things. Cables can be damaged in many ways. Um, I mean, you can damage them, loading them onto the ship. You can damage them in offloading of the ship. Failure modes are stretch, stretching, compression, bending if you exceed a certain [00:09:00] radius when you bend it. Um, because remember the export cable is gonna be, I mean, half a meter across at a minimum, right?

They’re, they’re huge. So, um, you even go to the point where. There’s a, there’s a concept called touchdown monitoring. So you’ll have the cable lay vessel, and there’s the stinger that sticks out the back, that the cable comes outta the reel and goes down the stinger. When it goes off the stinger, it cannot exceed a certain radius, and when it gets to the ground, it can’t exceed a certain radius, uh, of curvature.

So there’ll be an ROV, a remote operated vehicle, that camera down there flying along with the vessel to watch that radius to see how it’s doing. And that’s the touchdown monitoring part of it. So they know a lot of times. If they’re laying, if they have an issue. The trouble here is splicing a cable like that when there’s a break or a problem, like it’s damn near impossible.

Now, the Greater UA project is in shallow enough water where you can put divers down. So there’s a possibility of putting a bell, putting an enclosure and splicing something, [00:10:00] but oof, that’s expensive too.

Rosemary Barnes: But is there any suggestion that it was, um, that, was it sabotaged? Was it accidental? Because that’s what my, um, worry is, uh, with this happening in that region.

Even if it, it was just, you know, one of those, um, so somewhat mundane failure modes that you described, it probably is gonna bring to everybody, like front of everybody’s mind, um, that. Yeah, sabotage of a cable is a really, a really good way to be able to take out a whole wind farm. Um, and in that region, at least, like they’re really struggling for renewable energy solutions.

And if they’re not trusting in subsea cables, then, which is already problematic because a lot of the neighbors in that region don’t want to be trusting, um, trusting each other with something as critical as. Electricity supply. Um, but yeah, I think, you know, if they have to rule out subsea cables because they’re perceived security risk, um, or real one, then, you know, then they’re going down to some of the crazier options like Japan’s [00:11:00] looking at where it’s like, we’re gonna import liquid hydrogen, we’re going to coal-fire ammonia in our coal plants.

Uh, you know, all these sorts of things that just get more and more and more expensive than just putting electricity down a, a cable. So, yeah, I, I just wonder if anybody’s talking about, um, about the security aspect of it.

Joel Saxum: It seems that it’s in construction and when you’re under construction, of course there’s gonna be a ton of vessels around there.

So there, I wouldn’t suspect it was actual sabotage. I would think this is just a construction thing and there, and another reason behind that is an offshore construction in general, whether it’s p I’m talking pipe and cable lay and pipe and cable lay accidents, incidents. Losses happen quite regularly, really at a kind of a high rate compared to other things.

So I don’t think it would be a sabotage problem, uh, right now, but who knows in the future as well.

Allen Hall: Well, I just asked chat GPT, because this is the only place I can actually find some information about it. There’s really nothing online talking about what actually caused the damage in chat. [00:12:00] GPT as Rosemary pointed out.

Gotta be careful, but let me just read you what it says right now. Uh, the Chenwa Telecom subsea cable was damaged earlier this year in January, and it looks like a potentially Chinese linked, uh, ship happened to do that damage. So this sounds familiar to some things that have happened over, uh, in near Northern Europe.

Sure. Yeah. Oops.

Rosemary Barnes: Ask chat GPT for its source, because if you couldn’t find anything on the internet. How did it, it’s not like it has friends in the industry that are talking to it, you know? Um, so I, yeah. Is that a, a hallucination that’s, you know, gonna start an international incident?

Allen Hall: Yeah. You think this podcast could start an international incident?

That would be interesting. That I’d want to hear, but, uh, no. It does seem like a, a, a cable was damaged as, uh, earlier this year, and it wouldn’t be the first time that China was involved in cable damage. And it would be normal not to talk about it if it was sabotaged. So it does [00:13:00] seem a little bit odd that, uh, you don’t hear anything about it.

But back to Joel’s point, if it is an insurance claim, the insurance company’s not gonna talk about it. No. Or is not gonna talk about it because it’s under dispute probably. But, um, back to your comments earlier, Joel, about watching all this happen underwater and watching the cable drop. They know what the, the bottom of the sea looks like, where this cable is supposed to go.

Have many, haven’t they removed all the big obstacles for the cable to actually lay down or do they have a route that avoids

Joel Saxum: all that? Yes and no. Um, so I’ve been watching some of the geotechnic on that, uh, in that area, and there are very difficult geotechnic. Um, so if you remember a few, maybe last summer there was a jack up rig that, that fell over.

Over there. Right? Okay, so that’s difficult. Geotechnic, right? So when you’re running a, when you’re running a geotechnical study on a cable layer route, usually it goes like this. You’ll cruise down it with [00:14:00] multi-beam echo cylinders, so you can see the surface basically. So you can read what’s there, rocks do, sand, whatever, and you do a wide sloth.

You have it covered maybe a couple hundred meters wide, the whole route. Then along that route you’ll pick, um, like every kilometer, this will be the spec. Like every kilometer you’re gonna do a core. So you’re gonna do a gravity core or a drilling core to get a core sample of that sediment and be, be able to pull it out and see, okay, what’s actually here?

And then every half a kilometer, you’ll do like a simple VIO core or something like that, a CPT push test. But that leaves pockets right in this, in this area. Like when that, um. Jack up rig went over, they had done a bunch of, around a, around a site, around an actual, where you put a mono pile in. You’re gonna do a lot of surveys, you’re gonna do a bunch of CPTs in that area to kind of create a network of what that subsurface looks like.

But you can hit gas pockets, you can hit soft soil pockets, compaction, liquification, [00:15:00] different things that you didn’t, because you didn’t test every meter. You can hit these things, right? So there is a possibility that you’re laying this cable or, or in this, in this case, it sounds like this thing may have been a anchor drag or something, but there is a possibility that you’re laying this heavy cable and you’re on sand, sand, sand, and what looks like sand, but it’s actually like a liquified sand.

And all of a sudden the cable dives under the surface because that cable’s heavy and a lot of pressure on it. So that can happen without you knowing, and that’s why you’re doing the touchdown monitoring and all those kind of things.

Allen Hall: So is this similar to when you watch LinkedIn and you’re putting in a monopile and it just keeps going?

Joel Saxum: Yeah. That’s the exact same thing. When you’re like, do 2, 2, 2, 2, 2, they get through a hard sauce, plump. That’s, and it’s just gone. Yeah.

Phil Totaro: Insurance is obviously gonna be a part of this. The bigger conversation on insurance, however. Uh, that’s triggered by stuff like this is at the end of the day, the developer puts, you know, in this case Ted, they put a, a modest amount of margin, uh, [00:16:00] into their budget when.

You know, they, they go and ask for capital. When you get some kind of a delay, whether it’s, you know, induced by a government shutdown, or you know, an incident with a cable, whatever the cause is, the, the reality of that is you’re gonna blow through your management reserve in like a week or maybe a month, and you’ve, you, you know, you’ve got very tight margins already.

And you’re setting yourself up for a money losing project if you can’t make sure that you leverage all these technologies. Joel just explained they’ve already started increasing premiums and decreasing terms for. Insurance policies, whereas they might have signed like a three year or five year term on a policy, now they’re only signing a one year term and they’re increasing premiums by at least 20%.

From what I’ve understood from, from folks in the insurance industry. So. Things like this, [00:17:00] again, whatever the cause of, of the cable cut, you know, having those kind of challenges makes it definitively, um, more expensive for all of us because at the end of the day, you know, we as electricity rate payers have to buy this electricity from whatever the power generation source is, and we’re the ones that pay off that project.

And you know, if a developer’s not able to make money on a project, they’re not gonna build a project.

Joel Saxum: So Rosemary, with that, those kind of things in mind, have you heard of any of the site suitability, subsea, subsurface studies going on in the offshore wind projects in Australia?

Rosemary Barnes: Yeah, not so much. All I have heard about is, um, just that the water is very deep.

For the most part. It drops, drops off. Quickly across most of Australia. So that’s why they’re already even looking at some floating offshore wind projects in Australia, which is kind of crazy because we’ve got so [00:18:00] many, like amazing, uh, onshore sites left, including some with, with potential capacity factors in the high forties.

So it’s like, that’s as good as an offshore wind site, but it’s cheap, like an onshore wind site. So yeah, so that’s a bit. A bit crazy. Um, and also just, uh, I’ve been following the progress of the, um, sun cable project, you know, so it’s not offshore wind, but it’s a big cable that they’re planning to put in between, um, Darwin and Singapore, via Indonesia.

And, um, I just, just have been looking Yeah. Keep keeping an, an eye on it over the last, I know like. Five more years, probably nearly 10 years by now. And the length of the cable, um, has grown and grown and grown as they understand more and more, um, accurately what the root is actually gonna be. So obviously they have to go around some obstacles and it’s adding, you know, hundreds of kilometers every time that they have to do something like that.

So, [00:19:00] um, yeah, I don’t think it’s super easy. Um, yeah. But there are plenty of, uh, plenty of offshore. Gas exploration in parts of Australia. So I am sure that those parts at least, are

Phil Totaro: well understood. And Joel, I’ll answer part of your question. They have only started doing. Uh, any geotechnical and subsurface stuff on, uh, star of the South in Victoria.

And I think one other project that it was suppo, well, actually no, they, they were gonna move forward and then they pulled the plug on the Nova Castran project. Um, so there’s one, one project so far that’s getting any underwater work done, uh, at this point. So, uh, the, the challenge frankly, in Australia has been that the developers want to be able to build the projects, but they’re still not really the best regulatory framework in place for this.

The approvals have come way too [00:20:00] slow. Um, they. You know, part of, uh, a lot of the projects that were gonna be built in Western Australia was gonna be for powering hydrogen production, but then they’re competing with, you know, the Asian Power Hub or something that was supposed to be like 70 gigawatts of um, you know, onshore renewables, both wind and solar that we’re gonna also.

Be leveraged for, for hydrogen production. So, you know, the, the, the challenge for the Australian market is that they, as Rosie’s saying, you know, they have a lot of. Onshore renewables, you know, wind, yes. But also solar resources left in the tank. So you know, unless they’re actually seeing a huge spike in demand or they find somebody that’s going to do a lot of this hydrogen offtake and they can justify building these mega projects for, for doing it, I think they’re gonna have a hard time [00:21:00] with getting offshore in Australia, kind of off the.

Off the starting blocks.

Joel Saxum: Yeah. I think Phil, I’d have to agree with you there a little bit because, uh, my reasoning being in the last year and a half, we’ve done, of course, we’ve been talking about Australia with Rosemary for years, but we’ve done actual work down there. We’ve, we’ve dealt with, um, not dealt with, we’ve engaged with some of the locals.

We’ve, we’ve worked with some of the operators. We’ve worked with some of the great people down there that are running wind farms. Uh, they’re the engineers, the asset performance people, the developers, all the above, even OEMs. And you can see some of the struggles that they run into, um, just on land. Um.

With permitting and the, uh, local opposition and some things. And so you can hear the, the opposition to a lot of the wind projects there. And I, I gotta think that the permitting they’re gonna have, regardless of technical issues, the just getting through things through the government are gonna be tough.

To get offshore wind built,

Choose Eco Pitch for peace of mind. Contact Onyx Insight today to schedule your demo of Eagle Pitch and experience the future of blade monitoring.

Well as wind progresses in Japan. Offshore is a growing. Concept. Uh, but they’ve had trouble, right? Uh, Mitsubishi pulled out of three projects recently that they had bid on and won. Uh, but Japan is refusing to give up on offshore wind, and they are going to start planning a national floating [00:23:00] wind test center next year, and that is going to help them.

Get floating wind into Japan. So the, the Floating Offshore Wind Technology Resource Association, uh, says that they’re gonna conduct verification tests in Japanese waters because their ocean and weather conditions differ from Europe. Obviously, uh, there’s a lot of knowledge in Europe for floating wind.

Not so much in Japan. Uh, and I guess from my perspective, just reading these articles about Japan taking on this effort, it does make sense because the way the Continental shelf is right there off the coast of Japan, it pretty much gets into deep water very quickly. Floating wind is gonna be a great opportunity, but there are unique challenges in Japan.

Right.

Joel Saxum: Yeah. I, I wanna mirror this one almost in the conversation that we had with the fellows up in, uh, Norway and Denmark there about the Ute Sierra Nord. Right, because we talk to them about, okay, Norway having the capabilities to do this. Do we want to be a net exporter of technology? [00:24:00] Do we wanna bring it, keep it at home, we know how to do stuff offshore, blah blah, blah, blah, blah.

Um, great things up there. This is kind of the same case and put around the world, right? Japan is sitting over there, you know, mostly by itself working on floating wind stuff. So. It’s difficult. I mean, a lot of Japanese companies have tried to get into the offshore merge, you know, the MHI Vestas experiment and some of those other things.

Um, we, we, you know, we did a big strike take project and a bunch of Mitsubishi turbines onshore in the states this year. So like the Japanese technology’s been around the world, but I think that because of the national interest, right, like they won offshore wind, um, they have good offshore wind resource.

We’ve talked with quite a few people over there. Uh, they need. To do something like this. The only other one place that there’s an offshore wind test center, of course we have like high wind Scotland, um, there that did that, did that project. But there is another loading offshore like kind of test center in north, north of France, I think, where they’re doing some, some, some studies and some other things.

But them [00:25:00] building this, because Japan has been a follow on technology-wise, for years, they’ve just been using whatever the western world’s been creating. Um, and some Korean turbines, and we’ve run into some weird ones like that too, right? Some small production units. But I think that this one is, is very smart of them from a national interest standpoint to build this floating offshore technology center because they’re gonna need it.

If they want offshore wind, it’s going to have to be floating in a big way over in.

Phil Totaro: Port Portugal’s also got the wind Float Atlantic. So there, there are, you know, uh, again, a number of, of pilot projects. Japan was actually the pioneer though with this. They had a two megawatt unit, uh, out on a floating platform since I wanna say 2011 or 2012.

Their government needs to get out of their own way. If they really want to move forward with floating offshore in a serious way. The fact that they’re willing to commit some resources to this is good because they’re leveraging expertise as well from, um, you know, commercial [00:26:00] relationships with some of the other, you know, floating research centers around the world, including Norway.

Um, according to this, this press release, uh, announcing this. So, you know, in general that’s a good thing, but. You know, all it takes is somebody saying yes at this point. And you know, there’s, there’s been a lot of people pushing for this for a long time, uh, both in Japan and in the West, who wanna be, you know, in Japan, including turbine OEMs, developers, uh, financiers, you name it.

Uh, the government needs to. You know, get out of its own way and let some of this start, start to flourish.

Joel Saxum: Alright, the Wind Farm of the week. This week we’re taking a, a plane trip across the Atlantic to Moray West, which is an Ocean Winds project. Ocean winds is EDPR and NG. Uh, so on this offshore wind charm is 60 Siemens esis SG 14.

2, 2, 2 direct drive turbines each rated at 14.7 megawatts. Uh, these things have a big [00:27:00] 108 meter power boost blades on them, which are just massive, 108 meters long for each blade. Uh, so the cool thing about this wind farm and they’re doing something a little bit different ’cause we have spoke about a lot of these offshore wind auctions and how the CFDs are working in the UK and, and some of the interest or disinterest in the Danish auctions and German auctions.

You know, support for the actual financing and operators. They did something a little bit different on this one. It’s a hybrid financial structuring model for offtake, which is pretty cool. Um, so unlike most UK offshore wind farms that rely entirely on CFDs, Moray West has 882 megawatts. Uh, it splits it into three buckets, 294 megawatts under a government UK CFD.

573 megawatts are under big tech PPAs with Amazon and Google. And then a and then a little bit of it is, uh, in, in the merchant markets. Um. So that hybrid model had secured them 2 billion pounds in financing. [00:28:00] Uh, so it’s a bit of a different way to do things right when they’re building this up. So they brought a lot of, lot of, uh, support to the local economies there up in, in Scotland, so Port of Nig, uh, the Port of Inver Gordon, uh, the key west there.

So they had some marshaling, uh, areas and pre-assembly areas. Uh. Some local North Sea vessels from cattle for, to help install. Uh, and all of this translated, so the cool hybrid model, um, the financing that was there on, uh, the, all of the support locally had some rapid project delivery. So they were able to first secure the consent to 2019 and they dev, they delivered first power in July of 24 and full power output by 25.

So for an offshore wind project going con from consent. To full power in under six years. Pretty impressive. Um, so this, this project, local economic impact is expected to inject 800 million pounds [00:29:00] into the Scottish economy with over 1500 full-time employee years of construction jobs and 60 plus long-term operational roles based in Bucky.

Uh, so it really demonstrates the offshore wind can support energy transition and regional economic development amid some supply chain and grid infrastructure challenges. So. The Moray West Wind Farm up there in Scotland U are our wind farm of the week.

Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow

Allen Hall 2025: Well, Rosemary, welcome back to the show.

Rosemary Barnes: Thanks, Allen. Great to be here. For, it’s been a while since we did one of these one-on-one episodes, like a, yeah, a proper, proper guest. 

Allen Hall 2025: Well, this is kind of a celebratory episode because your company, Pardalote Consulting, has been awarded, uh, some funding from the Australian Capital Territory’s government for the Energy Innovation Fund.

Rosemary Barnes: It’s a really good program that the ACT government has to try and get energy innovation In the state. It’s not a state actually, it’s technically a territory. Little more than just Canberra, the city. Uh, but there are actually quite a few, like, really interesting energy-related companies here, partly ’cause of the, the fund I think helps, but also just tracing back like, [00:01:00] uh, y- you know, in the 20-teens, Australia had a really conservative government that hated renewable energy, and the ACT government had a commitment at that time to 100%, um, 100% renewable electricity for the, the government.

And that was one of the only programs that was resulting in a lot of, um, you know, clean energy projects being built, and one of the conditions that they put on that, uh, for people that would win PPAs with the ACT was that you had to have your headquarters in Canberra. So we’ve actually got quite a few, quite a few really cool, innovative companies out of here.

Um, like Neoen’s headquarters here. Windlab, uh, yeah, was, was founded here and still has a lot of people here. Pardalote obviously, and you know, a few other companies as well. So despite it being a small city of like, I don’t know, maybe it’s up to 400,000 or something people by now, um, yeah, there is actually quite a lot going on here for energy.

Allen Hall 2025: And the Energy Innovation Fund is funded by the wind and solar operators in the area, and your particular [00:02:00] effort has really global consequences. You’re focusing on two areas involving how wind turbines survive Australia, but more, uh, of relevance is to just really tough conditions which exist not just in Australia but around the world.

What two areas are you going to focus on?

Rosemary Barnes: Yeah. So the two focus areas are leading edge erosion and high temperature fatigue, which we can probably get into the definitions of those in a minute. But basically my, um– what led me to wanna have a project like this was that when I moved back to Australia in 2021, I– and I started working in O&M, uh, I noticed that the wind turbines that I would look at, the blades that I would look at here behaved really differently to the ones that I worked with overseas.

You know, es- especially with leading edge erosion, like often I would be doing a condition assessment of a, you know, a new wind farm. Um, might only have been operating for, you know, two years. That’s a pretty common time for people to get in and do a condition assessment [00:03:00] because their warranty period is about to end and they wanna, you know, make sure that everything is okay.

Um, and I would just notice that often, like 90, 100% of blades would already have bad erosion after just a couple of years, which is super-duper fast. And then there are some tools available to check, um, like what kind of erosion are you likely to experience on your site. Like is it a higher severity erosion site or a, a low severity one?

Um, and you basically, you know, the status quo globally is to just look at the annual rainfall, um, and the tip speed. And if you’ve got, you know, high for both of those, that’s a bad erosion site. And if you’ve got low for both of those, it’s a, a low erosion site. But when I plotted out the wind farms that I knew had really bad erosion problems onto, you know, a chart with those two axes, I just saw a random distribution of dots.

You know? Like, this was not– uh, this had no predictive value for Australian wind farms. And so that led me to believe that, okay, um, you know, things are a bit [00:04:00] different here. Makes sense, you know, most of the knowledge that we have about how wind turbines operate, it’s been developed and validated mostly in Northern Europe.

You know? Like it’s, it’s Denmark and the surrounding countries that had, like, the bulk of the early wind energy. First few decades of knowledge were, you know, were mostly there. Of course, there were some other, um, places that had wind turbines, but, you know, most of the The OEMs have been operating for decades, came from Denmark.

And I know when I lived in Denmark, the rain there is very different to the rain in Australia. So in Denmark, it’s basically always raining, right? Like, it’s just… Like, even if it’s not raining, you’re still gonna get wet when you go outside ’cause it’s just, like, the air has this just amazing ability to just hold onto moisture.

Um, but it’s very, very gentle. But, you know, over an entire year of most days having gentle rain, that adds up to a lot. Whereas in Australia, and especially if you go, like, north to Queensland, it rarely rains. It’s mostly just dry, and when it [00:05:00] does rain, it’s like a tap turns on, and I, I swear you will get bruised from the rain droplets hitting your skin.

You know, they just have so much energy in them. So I think that that i- you know, when you look at just the overall rainfall, you really hide something important about how erosion, um, can progress. Then, um, there’s other places in Australia that have very different characteristics. Again, they don’t have that kind of really intense rain but, you know, some of those sites are also having really bad erosion.

And so it just occurred to me, I did a lot of research, you know, into what’s going on and, you know, the academics are studying erosion a whole lot, and they’ve got, you know, a lot of standardized tests and, you know, products are developed according to these standardized tests. But the standardized tests don’t actually resemble reality, and especially they don’t resemble reality in Australia.

And so my client started asking me, “Okay, you know, the products that we have are, are terrible. We have to replace them every couple of years. It’s, um, causing big problems with also [00:06:00] the amount of energy that you’re losing.” One of the types of, um, leading-edge erosion or leading-edge problems that we have in Australia is that the, the coatings tend to peel off and make these, like, big flakes which will just massively disrupt the airflow, can cause y- you know, at least a few percent AEP loss, and maybe up to five.

And even worse than the AEP loss is the revenue loss because it affects it most at, you know, lower wind speeds. Um, you get a bigger hit than at rated wind speeds. So there’s a variety of problems going on with leading edges in Australia, which mean that I, I basically… My clients would ask, “What product should we put on to prevent having to, you know, constantly replace this?”

‘Cause it costs, like- you know, 30, $40,000 per turbine to replace the protection, not to mention, you know, one or two days of downtime. It’s expensive, and I basically, I didn’t have a good answer for them. What, what product should they put on? I don’t know. No, we, we don’t know. One, we don’t know what the [00:07:00] specific, um, characteristics are that are…

what the specific local environment, local conditions are that are accelerating leading-edge erosion, one. And two, all of the products tend to be tested around this, you know, there’s this protocol that academics have come up with, and they’ve kind of like assumed that this is representative of how things behave in the field, and it’s– I don’t think it’s particularly true anyway, but it’s especially not true in Australia.

There are a few companies that are testing to different standards. Um, definitely applaud them. But without knowing wha- what are the conditions truly like in Australia, uh, it’s really hard to advise, like, what kind of tests should you be demanding from a product you’re considering to be sure that you’re gonna put it on and not gonna be replacing it again in two years.

Allen Hall 2025: Because that’s really the trouble in Australia is when you get offered products They have been tested generally in somewhere in Europe and maybe in the United States, and then when they go to [00:08:00] Australia, it’s really unknown as to how those products will do, which is a huge risk for the Australian wind market as to what to choose, how to choose, is it– what’s real in terms of test data.

So now you’re gonna go out and do what? Are you gonna put sensors out by the wind farms? Are you gonna try to do more of a statistical summary of the actual environment around wind farms using existing data? What’s the approach here?

Rosemary Barnes: It’s all of the above, but the part that is supported by the grant is that we’re gonna have enough money to be able to buy some scientific-grade sensors and put them on, um, a sample of Australian wind farms.

So we’re gonna be looking at a lot more characteristics about the rain than simply is it raining now, you know, how many millimeters per hour. We’re also gonna be investigating, you know, every kind of characteristic of, of that, um, of that rain, um, including, yeah, like the, the energy that’s in it, for example.

A, a bunch of stuff. I won’t get into every single [00:09:00] parameter. Um, and you know, other things as well, like measuring UV, solar radiation, um, particles, because, you know, in Australia we have a lot of dirt roads, which I know is very common in wind farms around the world, but Australian dirt roa- roads are always dry and dusty, like 99% of the time, so that’s one of the things that y- you know, maybe that’s causing a difference.

Um, so basically putting sensors all over a bunch of wind turbines and then monitoring the erosion, um, a combination of some real-time monitoring and also looking at inspection, um, drone inspection images annually. We also have a- an option where we’ll just be using SCADA data and inspection images, so that’s like a lower cost version where we can combine that with the findings from the scientific-grade instrumented turbines to build up a picture of what types of conditions lead to accelerated erosion.[00:10:00]

Allen Hall 2025: So the SCADA data will, will have some information inside of it, you think, that, uh, will correlate to the weather outside?

Rosemary Barnes: It has some Additionally, we can look up, um, you know, just the weather data, like how many millimeters fell during which 15-minute interval throughout the day, what was the temperature.

SCADA will tell us also what the temperature was, um, what the speed of the turbine was, so you can calculate the tip speed, ’cause that’s an important thing. Um, yeah, so it’s, it’s two, it’s two tiers of data collection. The scientific grade sensors, as you can imagine, are, are really expensive and y- you know, the, the grant project has contributed a, a lot of funding, um, but it’s not enough to put those, yeah, put a little mini lab on top of every turbine across Australia, obviously.

So that we’re using s- doing selectively, and then we can increase the number of wind farms that are included in the study by just doing this, um, cheaper version of the SCADA [00:11:00] plus, uh, weather data that’s available.

Allen Hall 2025: So what are some of the risks on the temperature side for all the high-temperature regions of Australia that have wind turbines?

Clearly it’s generally warmer in Australia than it is in, in Scandinavia and Northern Europe. What kind of temperatures are we talking about on the ground?

Rosemary Barnes: Uh, well, temperatures here can get pretty close to 50 degrees. Um, and if you’ve ever been inside a wind turbine blade on a, even a mildly hot day, you’ll know that the temperature inside a wind turbine, and especially inside the blade, is much hotter than what it is, uh, what the ambient temperature is.

So this project is one– I’ve actually been talking about this project for, yeah, like over 10 years now. Ever since I started, I moved to Denmark, started working for a wind turbine manufacturer, I had done– I had just finished doing my PhD on composite materials, structural design, and analysis. So, um, yeah, very, very familiar with, [00:12:00] you know, how composite materials work and, in particular, the effect that temperature has on them.

I mean, like most materials, when composites get warmer, they get softer, and that is really important for a w- a wind turbine blade. You know, if it gets, um, less stiff, then you’re gonna get a lot more strain, and that is going to affect your fatigue behavior. Y- you know, fatigue is just the application of a little bit of, a small amount of strain.

It’s not gonna cause damage, but when you apply it millions, tens of millions of times, like you do in a, o- over a wind turbine’s operate, um, operating lifetime, then that builds up. And, you know, wind turbine blades are a very fatigue-driven design. Um, it’s one of the most important things to consider when you’re designing a wind turbine blade.

And so when I got to Denmark and I learned how materials are qualified and how the qualification is treated in the certification process, I just realized it’s not particularly conservative, and also that some of the assumptions that are made that [00:13:00] wo- again, they worked really well in more moderate climates where wind turbines have had most of their developmental history.

You know, it’s not such a big deal there if you test at room temperature. Your wind turbine blade is spending most of its operating lifetime at room temperature or below. It’s, it’s rarely, you know, above 30 degrees in Denmark and most of Northern Europe and, you know, also a lot of, um, a lot of America, not, not all of it But, um, in Australia it has just extended periods above that temperature and even exceeding the temperature where, you know, wind turbines have an operating limit and after that they will shut down.

But the operating limits are based on ambient temperature. It’s not based on what’s the temperature in the laminate, which is what really matters for blade lifetime. So anyway, I’ve been obsessed, like honestly obsessed about this issue for 10 years. Talked about it with anybody who would listen . But then when I started working in O&M in [00:14:00] Australia and I started seeing some wind farms with an abnormal number of cracks early…

again, early in their lifetime, you know, I think one of the wind farms I was looking at was maybe three years old or four at the time. I think it was three actually, and had a lot of cracks, and I looked at a few years in a row and it was more and more cracks every year and I’m like, “Oof, this really looks like end of life fatigue behavior.”

A- actually it’s not, y- you know, there’s this concept of a bathtub curve where, um, when you’re looking at failures in components, in, in anything, not just in, um, wind turbine blades, but you know, like you’d start– it’s called a bathtub because, you know, when it starts operating, you’ll get quite a lot of failures.

Anything big, any manufacturing defects or anything are gonna cause failures quite fast, and that kind of drops off over time as all of those, uh, get addressed. And then you have, you know, the bulk of your operating life, it’s like pretty low level, pretty, pretty constant for a long time and then as you get towards the end of the [00:15:00] life, you start to see failure rates rise up again.

That’s your fatigue failures, your end of life fatigue failures. And so when I saw the same types of cracks more and more each year, I’m like, “This looks like, you know, the foot end of the bathtub, not the head end.” And, uh, it made me worried and I’ve now seen that across a few wind farms in Australia at, um, hotter places.

There’s a few blade types that are more prone to it than others, but at this point it’s still a suspicion that that’s what’s going on. I mean, a suspicion backed by a lot of, a lot of theory and knowledge of how the certification process works. But this project now we’ve got some funding to actually go put some sensors onto wind turbines, actually learn what the temperatures are in the blades throughout the whole laminate, um, not just the, you know, on the outside surface or not just the ambient temperature, but actually, you know, develop a temperature gradient across the whole, um, the whole laminate in the blade shell.

Um, and [00:16:00] then we’re going to be doing a bunch of modeling basically to look at what is the effect of these different temperatures that blades are really seeing and how much would we expect to… that to decrease a lifetime. And then we should also be able to say, you know, if you have this issue in your wind farm, you might be able to change your operation a little bit and extend your lifetime a lot.

Because this one, it’s real– like, in contrast to leading edge erosion, leading edge erosion is just, it’s, you know, every wind turbine has it to a certain extent, and it, it’s always there, but it’s a relatively minor cost to fix it. You know, like it sounds like a lot, like 30, $40,000 per wind turbine, but, um, you know, compared to if you’ve got to replace every blade across your fleet because they’re all, you know, at the end of their life after five years, you know, that’s obviously shocking.

And, you know, that’s a bad example, but even in a y- you know, like a less extreme example, maybe [00:17:00] after 15 years you have to do a, you know, a f- a fleet-wide campaign to strengthen blades or something. It’s, you know, m- many millions of dollars for that, and so it c- could make sense to be able to learn, okay, what, what hours of operation should we be avoiding?

Additionally, because when it’s super-duper hot in Australia, usually you’ve got heaps of solar power and the electricity price is not that high. So I, I think that there– and I don’t, obviously, before we’ve done the project, I don’t know what the threshold is. But in both cases, we will be aiming to improve the knowledge of how you can operate to avoid these periods of accelerated damage.

Allen Hall 2025: Do you think you’re seeing more fatigue-like damage due to the blades operating when it’s hot or not operating when it’s hot, with maybe less airflow around the blade and maybe less cooling going on is just a temperature soak At rest? [00:18:00]

Rosemary Barnes: Yeah. It’s interesting because the temperature is higher if it’s not rotating, um, because you get a whole lot of, um, convective heat, heat transfer when the turbine is operating.

So your temperatures are not gonna get as hot when operating as when they’re standing still. However, if it’s standing still, they’re only very lightly loaded. Like, yes, they’re gonna get, um, blown by, by gusts and, um, have a little bit of bending, but it’s, it’s very, very small compared to, uh, if it is y- you know, operational loads.

Uh, assuming that you’re not in the middle of a s- a storm. But yeah, a storm probably doesn’t come with 50 degrees temperatures.

Allen Hall 2025: And what part of the blade is susceptible to these higher temperatures? Is it the resin? Is it the fiberglass or carbon fiber? Or is it the, the glue, the bond joints? What part are you focused on?

Rosemary Barnes: The resin is the main part that I’m focused on. It gl- it could be an issue for glue too, actually. I haven’t even looked into what the, um, yeah, temperature assumptions are with, with glue, with [00:19:00] bond lines. But the failures that I’m seeing in the field are not, are not bond line issues. It’s, it’s, um, a laminate problem.

Allen Hall 2025: What about balsa and foam inside of the blade? Are they affected by the temperatures or are they pretty temperature stable?

Rosemary Barnes: I don’t think they’re affected at these kinds of temperatures, no. They, they don’t really do much actually. The, the core materials, like it, it is very important that they’re, that they’re there, but their job is really to keep the fiberglass separated from its- itself to make it stiffer.

So, um, yeah, that’s, that’s unlikely to be a, a major source of problems.

Allen Hall 2025: So this study is gonna work over about three years, and you have a number of wind farms that are participating. Are you looking for more wind farms to participate in Australia?

Rosemary Barnes: Yeah. Yeah, definitely. I mean, we can, um, have as many as, as people want to join.

We’ve got quite a good selection so far. Definitely can always welcome more. A, a bit limited in how many can get the really, um, good sensor [00:20:00]package, because the grant funding is a, you know, a certain amount, and that’s paying the bulk of those sensors. So, um, those spots are limited. So if anybody wants to really zone in on what is specifically causing erosion on their site, you know, if you know that you have got leading edge protection that is not good enough and you have to replace it soon, but you don’t know what to replace it with, then, you know, that would be the kind of wind farm that might want to consider, yeah, joining this and, um, you know, getting these sensors on their, um…

We’re putting them on top of the nacelles, most of them. Um, yeah, so that would be a good match then. Um, and then, yeah, for the ones that are doing the SCADA data and, um, weather data- There’s not such a, a hard limit on how many we can have join like that. So yeah, we can have more, more like that.

Allen Hall 2025: In the temperature fatigue effort, i- is that still looking for participants or are there particular wind turbine types or manufacturers that you’re [00:21:00] looking for to participate?

Rosemary Barnes: Yeah, I think, um, I, I mean yes, we can have more of those. That’s a simpler, a, a simpler issue as well. The sensors are not so expensive and, um, it’s, yeah, it’s a, it’s a simpler project to join that one. We only need, you know, a couple of turbines per site, so it won’t be such a, uh, an involved process to get everything up on into the turbines.

And in terms of who might like to join that, I would say anybody that is in a really hot area where, you know, where they see a lot of days over 30 degrees, and if they see any days, you know, getting into the high 40s, then I would say that that’s worthwhile. Or even I have seen this issue in some milder sites, um, yeah, depending on the, on the blade type as well.

It is more common with polyester resins. They have a, a lower op- uh, maximum operating temperature than epoxy resins. But then also just anybody that has noticed just, hey, [00:22:00] we’ve got a lot of cracks, and it seems like we’re getting more and more cracks every year, which to be honest, can be hard to keep track of if you’re…

If you’ve got a full service agreement, uh, you know, an OEM managing your wind farm The early signs of this are gonna be category one and category two cracks. They’re not in exactly the same location. It’s, you know, it’s a tricky one. Normally, if you’re looking at a serial issue, then you’re going to have, uh, well, you know, your ideal pattern for a serial issue is the exact same thing happening over and over again.

And so it is harder to pull this out. It also really would be very rare for it to be happening in the first two years or three years, whatever your serial defect liability period is. So it’s quite hard. But, um, another group of wind farms that might like to consider it is if you know that in, you know, a certain number of years you have to renegotiate your service agreement or, you know, it ends and you might have to take over yourself, then this’ll be a really good way for you to [00:23:00] understand, you know, have I got a ticking time bomb here?

Um, because it’s not something that you’re gonna be aware of if you haven’t been, you know, doing some really, really in-depth shadow, shadow monitoring of your blades, you know, running your own inspections and looking at every single damage, not just category three, four, five, but lower ones. So yeah, I mean, there’s a, a wide variety of people that, that could be interested in joining.

Allen Hall 2025: Are you expecting a number of manufacturers that make leading-edge protection or involved in resin creation, some– there’s a number of resin companies and a variety of resins that are used globally, sort of interchangeably at times. Are you expecting some of those companies to participate in this effort just to learn about the Australian environment?

Rosemary Barnes: I think it would be a good opportunity to test out some products and see how they behave in the Australian context. I think that that would be a really good selling point, but I, I have to say that most of the companies doing that sort of thing that wanna enter Australia, they don’t [00:24:00] really consider…

Like, from the perspective of wind farm owners in Australia, if you can’t show us wind farms in Australia where this has worked and, you know, show us a before or after, you know, the old LEP lasted Two years and our LEP is going on four years now with no damage. It, you know, unless you’ve got a before and after like that, you can tell us however many turbines that you’ve got installed around the world, but, um, we don’t consider it validated, y- you know?

It’s not validated for Australian conditions yet. And I do have this same discussion over and over again with, you know, not just leading edge protection, but all kinds of, um, you know, manufacturers of whatever doodads that you put on to improve a, a wind turbine. It’s so different to Australia. Things break so fast.

And I’m talking everything, you know, like vortex generators fall off and, um, yeah, like, uh, you know, bits of lightning protection systems fall off, seals just [00:25:00] crumble and disintegrate. Um, and it, you know, we’re very wary of, of new products. So I, I do– I mean, I’m thinking of it more from my client’s point of view than from the product manufacturer’s point of view.

But one thing that I wanna get out of this pro- project is to be able to answer one of the most common questions that I get is, which is, what leading edge protection should I be putting on my turbine? And for now, I don’t know. I, I know a range of products that don’t work in Australia, and not much more than that.

So, um, yeah. And it’s also, you know, Australia’s a very varied place with lots of different kinds of climate too. So it’s not gonna be like, you know, the product that works in Queensland is the same one that’s gonna work in Tasmania, which is the same one that’s gonna work in Western Australia. You know, um, so it, this project is gonna really pull out what are the site specific issues you’ve got at your site and what kinds of, um, you know, tests would we need to see a product um, perform in order to know that this [00:26:00] is gonna last on your site.

Allen Hall 2025: W- what is the outcome of this project or these two projects? Are they gonna be reports or, uh, a, a continual monitoring system that’s designed for the Australian environment? How do you see this going?

Rosemary Barnes: Yeah, so one part of it is, um, developing a way to identify periods of accelerated damage and to know not to operate during that time.

So we call it protective operation. Uh, so that would, uh, help you if, yeah, you’re trying to extend the life of something or increase the amount of time before you have to repair, then y- you know, that would be useful to have that knowledge. And it will be as simple as just an alert saying, “Hey, accelerated damage conditions.

Consider, you know, if you wanna keep on operating.” And, you know, if the price of electricity is super high at that time, they may want to push through, and if it’s low, they probably won’t want to. So that’s one thing. Um, especially, you know, as wind turbines get to their, near the end of their life. I’ve got some clients whose wind farms only have, you know, [00:27:00] maybe five years operation left.

They just simply don’t wanna repair their leading edge protection again. They just, they, they don’t wanna do that. So they would be happy to, you know, reduce operation a bit and have their turbine limp through to the end of the period. Y- you know, you want everything to wear out at once. You don’t want brand-new leading edge protection on a turbine that’s going to come down in a couple of years.

Um, so, you know, that’s, that’s one part of it. And then the other thing is, you know, turbines earlier in their lifetime, how can we optimize the maintenance schedule with leading edge erosion? Um, so, you know, like it’s a lot cheaper to, uh, replace the LEP if you get– catch it early, but then you don’t wanna be catching it too early and replacing it, you know, constantly when you, you don’t need to.

So, um, yeah, it, this, having this knowledge will enable a site-by-site operations and maintenance strategy with respect to leading edge protection. We also have some sites who are having trouble. They’ve got a full service agreement, and the OEM is [00:28:00] responsible for, um, doing the leading edge erosion repairs and protection replacement, but the owner is on the hook for paying for it.

At the other end, we’ve got people with full service agreements where technically the, um, manufacturer is supposed to be doing the leading edge protection and paying for it, but they argue about what, when does it need to be done. Because, you know, um, the operator might think if there’s no structural risk, then we don’t need to be replacing it.

And in the meantime, you’ve got turbines spinning around for years and years and years with, you know, these huge flakes of leading edge protection s- you know, causing the flow at the tip of the turbine to, to detach and to stall, and horrible aerodynamics, huge losses in power generation and revenue. And they’re having a big fight about, you know, is this necessary to do or not?

And then, you know, they’re just gonna put the exact same product on again ’cause the [00:29:00] OEMs are re- all really, really wedded to their own particular brand. It’s like, “Well, last time we had this product and it was factory applied, it lasted one year before it s- it was worse than, you know, if it wasn’t there at all.

Uh, we don’t really want you to put that one on again.” And so, you know, having the information that they need to be able to, you know, really bring data to these discussions and, you know, makes a, yeah, data not drama. That’s a, a good approach I think, um, for any kind of negotiation and especially in the case of leading edge erosion.

And then for the high temperature fatigue part of the problem, aside from, you know, just wanting to know are your blades aging, should you be looking at remediation action or changing the operation, the other really big key thing is, uh, you might need to have a fight with y- your OEM about if this turbine has been designed and operated correctly.

And so then having the data from this, um, project is going to give you the information that you need to come into that [00:30:00] argument with, again, the data not the drama. Um, and to, you know, in- increase your chances of succeeding in that kind of really tricky negotiation.

Allen Hall 2025: So if you’re an OEM or a manufacturer of equipment, an ISP, an operator, pretty much all aspects of wind operations, you probably ought to be getting a hold of Pardalote Consulting and Rosemary to talk about the opportunity to participate in this study.

How do people get ahold of you to, to do that?

Rosemary Barnes: People can go to our website, pardaloteconsulting.com, and get in touch via the contact form there, or you can, uh, look me up on LinkedIn, Rosemary Barnes. That’s probably the easiest, fastest way to get ahold of me personally.

Allen Hall 2025: Well, Rosemary, congratulations on the Energy Innovation Fund Awards and the new three-year effort.

If you are interested in participating with Pardalote Consulting and working with Rosemary and her team [00:31:00] in Australia, reach out to her on LinkedIn and get that process started, because this report and the data from all this analysis that’ll happen over the next couple of years will be important to the wind industry.

So you need to spend some time and get ahold of Rosemary and get this process started now. So Rosemary, congratulations. Uh, thanks for being back on the podcast, and looking forward to, uh, the next couple of years. It sh- should be exciting.

Rosemary Barnes: Thanks so much, Allen.

Artificial Stupidity?

We all understand that there are ultra-conservatives living all around us, but does anyone truly believe that our schoolteachers are ruining our society by teaching children the truth about U.S. and world history? Science? Current events?

Slavery and Jim Crow laws were bad.  Fascism is bad.  Our scientists are telling us that CO2 emissions are causing world temperatures to rise, destroying our planet’s capacity to support life.

Whom do these concepts upset?

No Such Thing as a “Dumb Question”

There is nothing dumb about the question posed at left.  Democracies fail, falling into “banana republics” constantly.  The rate at which democracies become tyrannies is so great that some of them never make the news. Can you tell me anything about the governments of Eritrea or Chad?

What makes the situation in the United States is, yes, that it’s happening here in the United States, the very last place anyone would have suspected it.

You might have thought that Americans wouldn’t have voted for their nation to become Russia or North Korea.

You would have been wrong.
