Allen Hall: Uptime Wind Energy Podcast. I’m your host, Alan Hall. I’m here with Yolanda Padron and Joel Saxon.

Rosemary Burns is climbing the Himalayas this week, and our top story is Semen’s Energy is rejecting the sail of their wind business, which is a very interesting take because obviously Siemens CESA has struggled. Recently due to some quality issues a couple of years ago, and, and back in 2024 to 25, that fiscal year, they lost a little over 1 billion euros.

But the CEO of Siemens energy says they’re gonna stick with the business and that they’re getting a lot of pressure, obviously, from hedge funds to do something with that business to, to raise the [00:01:00] valuations of Siemens energy. But, uh, the CEO is saying, uh, that. They’re not gonna spin it off and that would not solve any of the problems.

And they’re, they’re going to, uh, remain with the technology, uh, for the time being. And they think right now that Siemens Gomesa will be profitable in 2026. That’s an interesting take, uh, Joel, because we haven’t seen a lot of sales onshore or offshore from Siemens lately.

Joel Saxum: I think they’re crazy to lose. I don’t wanna put this in US dollars ’cause it resonates with my mind more, but 1.36 billion euros is probably what, 1.8 million or 1.8.

Billion dollars.

Allen Hall: Yeah. It’s, it’s about that. Yeah.

Joel Saxum: Yeah. So, so it’s compounding issues. We see this with a lot of the OEMs and blade manufacturers and stuff, right? They, they didn’t do any sales of their four x five x platform for like a year while they’re trying to reset the issues they had there. And now we know that they’re in the midst of some blade issues where they’re swapping blades at certain wind farms and those kind of things.[00:02:00]

But when they went to basically say, Hey, we’re back in the market, restarting, uh, sales. Yolanda, have you heard from any of your blade network of people buying those turbines?

Yolanda Padron: No, and I think, I mean, we’ve seen with other OEMs when they try to go back into getting more sales, they focus a lot on making their current customers happy, and I’m not sure that I’ve seen that with the, this group.

So it’s, it’s just a little bit of lose lose on both sides.

Joel Saxum: Yeah. And if you’re, if you’re trying to, if you’re having to go back and basically patch up relationships to make them happy. Uh, that four x five x was quite the flop, uh, I would say, uh, with the issues that it had. So, um, there’s, that’d be a lot of, a lot of, a lot of nice dinners and a lot of hand kissing and, and all kinds of stuff to make those relationships back to what they were.

Allen Hall: But at the time, Joel, that turbine fit a specific set of the marketplace, they had basically complete control of that when the four x five [00:03:00] x. Was an option and and early on it did seem to have pretty wide adoption. They were making good progress and then the quality issues popped up. What have we seen since and more recently in terms of.

The way that, uh, Siemens Ga Mesa has restructured their business. What have we heard?

Joel Saxum: Well, they, they leaned more and pointed more towards offshore, right? They wanted to be healthy in, they had offshore realm and make sales there. Um, and that portion, because it was a completely different turbine model, that portion went, went along well, but in the meantime, right, they fit that four x five x and when I say four x five x, of course, I mean four megawatt, five megawatt slot, right?

And if you look at, uh, the models that are out there for the onshore side of things. That, that’s kind of how they all fit. There was like, you know, GE was in that two x and, and, uh, uh, you know, mid two X range investors had the two point ohs, and there’s more turbine models coming into that space. And in the US when you go above basically 500 foot [00:04:00] above ground level, right?

So if your elevation is a thousand, once you hit 1500 for tip height on a turbine, you get into the next category of FAA, uh, airplane problems. So if you’re going to put in a. If you were gonna put in a four x or five x machine and you’re gonna have to deal with those problems anyways, why not put a five and a half, a six, a 6.8, which we’ve been seeing, right?

So the GE Cypress at 6.8, um, we’re hearing of um, not necessarily the United States, but envision putting in some seven, uh, plus megawatt machines out there on shore. So I think that people are making the leap past. Two x three x, and they’re saying like, oh, we could do a four x or five x, but if we’re gonna do that, why don’t we just put a six x in?

Allen Hall: Well, Siemens has set itself apart now with a 21 megawatt, uh, offshore turbine, which is in trials at the moment. That could be a real game changer, particularly because the amount of offshore wind that’ll happen around Europe. Does that then if you’re looking at the [00:05:00] order book for Siemens, when you saw a 21 Mega Hut turbine, that’s a lot of euros per turbine.

Somebody’s projecting within Siemens, uh, that they’re gonna break even in 2026. I think the way that they do that, it has to be some really nice offshore sales. Isn’t that the pathway?

Joel Saxum: Yeah. You look at the megawatt class and what happened there, right? So what was it two years ago? Vestas? Chief said, we are not building anything past the 15 megawatt right now.

So they have their, their V 2 36 15 megawatt dark drive model that they’re selling into the market, that they’re kind of like, this is the cap, like we’re working on this one now we’re gonna get this right. Which to be honest with you, that’s an approach that I like. Um, and then you have the ge So in this market, right, the, the big megawatt offshore ones for the Western OEMs, you have the GE 15 megawatt, Hayley IX, and GE.

ISS not selling more of those right now. So you have Vestas sitting at 15, GE at 15, but not doing anymore. [00:06:00] And GE was looking at developing an 18, but they have recently said we are not doing the 18 anymore. So now from western OEMs, the only big dog offshore turbine there is, is a 21. And again, if you were now that now this is working out opposite inverse in their favor, if you were going to put a 15 in, it’s not that much of a stretch engineering wise to put a 21 in right When it comes to.

The geotechnical investigations and how we need to make the foundations and the shipping and the this and the, that, 15 to 21, not that big of a deal, but 21 makes you that much, uh, more attractive, uh, offshore.

Allen Hall: Sure if fewer cables, fewer mono piles, everything gets a little bit simpler. Maybe that’s where Siemens sees the future.

That would, to me, is the only slot where Siemens can really gain ground quickly. Onshore is still gonna be a battle. It always is. Offshore is a little more, uh, difficult space, obviously, just because it’s really [00:07:00] Chinese turbines offshore, big Chinese turbines, 25 plus megawatt is what we’re talking about coming outta China or something.

European, 21 megawatt from Siemens.

Joel Saxum: Do the math right? That, uh, if, if you have, if you have won an offshore auction and you need to backfill into a megawatts or gigawatts of. Of demand for every three turbines that you would build at 15 or every four turbines you build at 15, you only need three at 21.

Right? And you’re still a little bit above capacity. So the big, one of the big cost drivers we know offshore is cables. You hit it on the head when you’re like, cables, cables, cables, inter array cables are freaking expensive. They’re not only expensive to build and lay, they’re expensive to ensure, they’re expensive to maintain.

There’s a lot of things here, so. When you talk about saving costs offshore, if you look at any of those cool models in the startup companies that are optimizing layouts and all these great things, a lot of [00:08:00] them are focusing on reducing cables because that’s a big, huge cost saver. Um, I, I think that’s, I mean, if I was building one and, and had the option right now, that’s where I would stare at offshore.

Allen Hall: Does anybody know when that Siemens 21 megawatt machine, which is being evaluated at a test site right now, when that will wrap up testing, is it gonna be in the next couple of months?

Joel Saxum: I think it’s at Estro.

Allen Hall: Yeah, it is, but I don’t remember when it was started. It was sometime during the fall of last year, so it’s probably been operational three, four months at this point.

Something like that.

Joel Saxum: If you trust Google, it says full commercial availability towards the end, uh, of 28.

Allen Hall: 28. Do you think that the, uh, that Siemens internally is trying to push that to the left on the schedule, bringing from 2028 back into maybe early 27? Remember, AR seven, uh, for the uk the auction round?[00:09:00]

Just happened, and that’s 8.4 gigawatts of offshore wind. You think Siemens is gonna make a big push to get into that, uh, into the water there for, for that auction, which is mostly RWE.

Joel Saxum: Yeah, so the prototype’s been installed for, since April 2nd, 2025. So it’s only been in there in the, and it’s only been flying for eight months.

Um, but yeah, I mean, RWE being a big German company, Siemens, ESA being a big German company. Uh, of course you would think they would want to go to the hometown and and get it out there, but will it be ready? I don’t know. I don’t know. I, I personally don’t know. And there’s probably people that are listening right now that do have this information.

If this turbine model has been specked in any of the pre-feed documentation or preferred turbine suppliers, I, I don’t know. Um, of course we, I’m sure someone does. It’s listening. Uh, reach out, shoot us at LinkedIn or something like that. Let us know, but. Uh, yeah, I mean, uh, [00:10:00] Yolanda, so, so from a Blades perspective, of course you’re our local, one of our local blade experts here.

It’s difficult to work, it’s gonna be difficult to work on these blades. It’s a 276 meter rotor, right? So it’s 135 meter blade. Is it worth it to go to that and install less of them than work on something a little bit smaller?

Yolanda Padron: I think it’s a, it’s a personal preference. I like the idea of having something that’s been done.

So if it’s something that I know or something that I, I know someone who’s worked with them, so there’s at least a colleague or something that I, I know that if there’s something off happening with the blade, I can talk to someone about it. Right? We can validate data with each other because love the OEMs, but they’re very, it’s very typical that they’ll say that anything is, you know.

Anything is, is not a serial defect and anything is force majeure and wow, this is the first time I’m seeing this in your [00:11:00] blade. Uh, so if it’s a new technology versus old technology, I’d rather have the old one just so I, I at least know what I’m dealing with. Uh, so I guess that answers the question as far as like these new experimental lights, right?

As far as. Whether I would rather have less blades to deal with. Yes, I’d rather have less bilities to, to deal with it. They were all, you know, known technologies and one was just larger than the other one.

Joel Saxum: Maybe it boils down to a CapEx question, right? So dollar per megawatt. What’s gonna be the cost of these things be?

Because we know right now could, yeah, kudos to Siemens CESA for actually putting this turbine out at atrial, or, I can’t remember if it’s Australia or if it’s Keyside somewhere. We know that the test blades are serial number 0 0 0 1 and zero two. Right. And we also know that when there’s a prototype blade being built, all of the, well, not all, but you know, the majority of the engineers that [00:12:00] have designed it are more than likely gonna be at the factory.

Like there’s gonna be heavy control on QA, QEC, like that. Those blades are gonna be built probably the best that you can build them to the design spec, right? They’re not big time serial production, yada, yada, yada. When this thing sits and cooks for a year, two years, and depending on what kind of blade issues we may see out of it, that comes with a caveat, right?

And that caveat being that that is basically prototype blade production and it has a lot of QC QA QC methodologies to it. And when we get to the point where now we’re taking that and going to serial blade production. That brings in some difficulties, or not difficulties, but like different qa, qc methodologies, um, and control over the end product.

So I like to see that they’re get letting this thing cook. I know GE did that with their, their new quote unquote workhorse, 6.8 cypress or whatever it is. That’s fantastic. Um, but knowing that these are prototype [00:13:00] machines, when we get into serial production. It kind of rears its head, right? You don’t know what issues might pop up.

Register now at WM a 2020 six.com. Wind Energy o and m Australia is created by wind professionals for wind professionals because this industry needs solutions, not speeches.

Allen Hall: While conventional blade inspections requires shutting down the turbine. And that costs money. Danish Startup, Qualy Drone has demonstrated a different approach [00:14:00] at the.

Ruan to Wind Farm in Danish waters. Working with RDBE, stack Craft Total Energies and DTU. The company flew a drone equipped with thermal cameras and artificial intelligence to inspect blades while they were still spinning. Uh, this is a pretty revolutionary concept being put into action right now ’cause I think everybody has talked about.

Wouldn’t it be nice if we could keep the turbines running and, and get blade inspections done? Well, it looks like quality drone has done it. Uh, the system identifies surface defects and potential internal damage in real time and without any fiscal contact, of course, and without interrupting power generations.

So as the technology is described, the drone just sits there. Steady as the blades rotate around. Uh, the technology comes from the Aquatic GO Project, uh, funded by Denmark’s, EUDP program. RDBE has [00:15:00] confirmed plans to expand use of the technology and quality. Drone says it has commercial solutions ready for the market.

Now we have all have questions about this. I think Joel, the first time I heard about this was probably a year and a half ago, two years ago in Amsterdam at one of the Blade conferences. And I said at the time, no way, but they, they do have a, a lot of data that’s available online. I, I’ve downloaded it and it’s being the engineer and looked at some of the videos and images they have produced.

They from what is available and what I saw, there’s a couple of turbines at DTU, some smaller turbines. Have you ever been to Rust, Gilda and been to DTU? They have a couple of turbines on site, so what it looked like they were using one of these smaller turbines, megawatt or maybe smaller turbine. Uh, to do this, uh, trial on, but they had thermal movie images and standard, you know, video images from a drone.

They were using [00:16:00] DGI and Maverick drones. Uh, pretty standard stuff, but I think the key comes in and the artificial intelligence bit. As you sit there and watch these blades go around, you gotta figure out where you are and what blades you’re looking at and try to splice these images together that I guess, conceptually would work.

But there’s a lot of. Hurdles here still, right?

Joel Saxum: Yeah. You have to go, go back from data analysis and data capture and all this stuff just to the basics of the sensor technology. You immediately will run into some sensor problems. Sensor problems being, if you’re trying to capture an image or video with RGB as a turbine is moving.

There’s just like you, you want to have bright light, a huge sensor to be able to capture things with super fast shutter speed. And you need a global shutter versus a rolling shutter to avoid some more of that motion blur. So there’s like, you start stepping up big time in the cost of the sensors and you have to have a really good RGB camera.

And then you go to thermal. So now thermal to have to capture good [00:17:00]quality thermal images of a wind turbine blade, you need backwards conditions than that. You need cloudy day. You don’t want to have shine sheen bright sunlight because you’re changing the heat signature of the blade. You are getting, uh, reflectance, reflectance messes with thermal imagery, imaging sensors.

So the ideal conditions are if you can get out there first thing in the morning when the sun is just coming up, but the sun’s kind of covered by clouds, um, that’s where you want to be. But then you say you take a pic or image and you do this of the front side of the blade, and then you go down to the backside.

Now you have different conditions because there’s, it’s been. Shaded there, but the reason that you need to have the turbine in motion to have thermal data make sense is you need the friction, right? So you need a crack to sit there and kind of vibrate amongst itself and create a localized heat signature.

Otherwise, the thermal [00:18:00] imagery doesn’t. Give you what you want unless you’re under the perfect conditions. Or you might be able to see, you know, like balsa core versus foam core versus a different resin layup and those kind of things that absorb heat at different rates. So you, you, you really need some specialist specialist knowledge to be able to assess this data as well.

Allen Hall: Well, Yolanda, from the asset management side, how much money would you generate by keeping the turbines running versus turning them off for a standard? Drone inspection. What does that cost look like for a, an American wind farm, a hundred turbines, something like that. What is that costing in terms of power?

Yolanda Padron: I mean, these turbines are small, right? So it’s not a lot to just turn it off for a second and, and be able to inspect it, right? Especially if you’re getting high quality images. I think my issues, a lot of this, this sounds like a really great project. It’s just. A lot of the current drone [00:19:00] inspections, you have them go through an AI filter, but you still, to be able to get a good quality analysis, you have to get a person to go through it.

Right. And I think there’s a lot more people in the industry, and correct me if I’m wrong, that have been trained and can look through an external drone inspection and just look at the images and say, okay, this is what this is Then. People who are trained to look at the thermal imaging pictures and say, okay, this is a crack, or this is, you know, you have lightning damage or this broke right there.

Uh, so you’d have to get a lot more specialized people to be able to do that. You can’t just, I mean, I wouldn’t trust AI right now to to be the sole. Thing going through that data. So you also have to get some sort of drone inspection, external drone inspection to be able to, [00:20:00] to quantify what exactly is real and what’s not.

And then, you know, Joel, you alluded to it earlier, but you don’t have high quality images right now. Right? Because you have to do the thermal sensing. So if you’re. If you’re, if you don’t have the high quality images that you need to be able to go back, if, if, if you have an issue to send a team or to talk to your OE em or something, you, you’re missing out on a lot of information, so, so I think maybe it would be a good, right now as it stands, it would be a good, it, it’d be complimentary to doing the external drone inspections.

I don’t think that they could fully replace them. Now.

Joel Saxum: Yeah, I think like going to your AI comment like that makes absolute sense because I mean, we’ve been doing external drone inspections for what, since 2016 and Yeah. And, and implementing AI and think about the data sets that, that [00:21:00] AI is trained on and it still makes mistakes regularly and it doesn’t matter, you know, like what provider you use.

All of those things need a human in the loop. So think about the, the what exists for the data set of thermal imagery of blades. There isn’t one. And then you still have to have the therm, the human in the loop. And when we talk to like our, our buddy Jeremy Hanks over at C-I-C-N-D-T, when you start getting into NDT specialists, because that’s what this is, is a form of NDT thermal is when you start getting into specialist, specialist, specialist, specialist, they become more expensive, more specialized.

It’s harder to do. Like, I just don’t think, and if you do the math on this, it’s like. They did this project for two years and spent 2 million US dollars per year for like 4 million US dollars total. I don’t think that’s the best use of $4 million right now. Wind,

Allen Hall: it’s a drop in the bucket. I think in terms of what the spend is over in Europe to make technologies better.

Offshore wind is the first thought because it is expensive to turn off a 15 or 20 megawatt turbine. You don’t want to do that [00:22:00] and be, because there’s fewer turbines when you turn one off, it does matter all of a sudden in, in terms of the grid, uh, stability, you would think so you, you just a loss of revenue too.

You don’t want to shut that thing down. But I go, I go back. To what I remember from a year and a half ago, two years ago, about the thermal imaging and, and seeing some things early on. Yeah, it can kind of see inside the blade, which is interesting to me. The one thing I thought was really more valuable was you could actually see turbulence on the blade.

You can get a sense of how the blade is performing because you can in certain, uh, aspect angles and certain temp, certain temperature ranges. You can see where friction builds up via turbulence, and you can see where you have problems on the blade. But I, I, I think as we were learning about. Blade problems, aerodynamic problems, your losses are going to be in the realm of a percent, maybe 2%.

So do you even care at that point? It, it must just come down then to being able to [00:23:00] keep a 15 megawatt turbine running. Okay, great. Uh, but I still think they’re gonna have some issues with the technology. But back to your point, Joel, the camera has to be either super, uh, sensitive. With high shutter speeds and the, and the right kind of light, because the tiff speeds are so high on a tiff speed on an offshore turbine, what a V 2 36 is like 103 meters per second.

That’s about two hundred and twenty two hundred thirty miles per hour. You’re talking about a race car and trying to capture that requires a lot of camera power. I’m interested about what Quality Drone is doing. I went to that website. There’s not a lot of information there yet. Hopefully there will be a lot more because if the technology proves out, if they can actually pull this off where the turbines are running.

Uh, I don’t know if to stop ’em. I think they have a lot of customers [00:24:00]offshore immediately, but also onshore. Yeah, onshore. I think it’s, it’s doable

Joel Saxum: just because you can. I’m gonna play devil’s advocate on this one because on the commercial side, because it took forever for us to even get. Like it took 3, 4, 5, 6 years for us to get to the point where you’re having a hundred percent coverage of autonomous drones.

And that was only because they only need to shut a turbine down for 20 minutes now. Right. The speed’s up way up. Yeah. And, and now we’re, we’re trying to get internals and a lot of people won’t even do internals. I’ve been to turbines where the hatches haven’t been open on the blades since installation, and they’re 13 years, 14 years old.

Right. So trying to get people just to do freaking internals is difficult. And then if they do, they’re like, ah, 10% of the fleet. You know, you have very rare, or you know, a or an identified serial of defect where people actually do internal inspections regularly. Um, and then, so, and, and if you talk about advanced inspection techniques, advanced inspection techniques are great for specific problems.

That’s the only thing they’re being [00:25:00] accepted for right now. Like NDT on route bushing pullouts, right? They, that’s the only way that you can really get into those and understand them. So specific specialty inspection techniques are being used in certain ways, but it’s very, very, very limited. Um, and talk to anybody that does NDT around the wind industry and they’ll tell you that.

So this to me, being a, another kind of niche inspection technology that I don’t know if it’s has the quality that it is need to. To dismount the incumbent, I guess is what I’m trying to say.

Allen Hall: Delamination and bond line failures and blades are difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production. C-I-C-N-D-T are specialists to detect these critical flaws before they become a. Expensive burdens. Their non-destructive test technology penetrates deep to blade materials to find voids and cracks.

Traditional inspections [00:26:00] completely. Miss C-I-C-N-D-T Maps. Every critical defect delivers actionable reports and provides support to get your blades back in service. So visit cic ndt.com because catching blade problems early will save you millions.

After five years of development, Alliant Energy is ready to build one of Wisconsin’s largest wind farms. The Columbia Wind Project in Columbia County would put more than 40 turbines across rural farmland generating about 270 megawatts of power for about 100,000 homes. The price tag is roughly $730 million for the project.

The more than 300 landowners have signed lease agreements already, and the company says these are next generation turbines. We’re not sure which ones yet, we’re gonna talk about that, that are taller and larger than older models. Uh, they’ll have to be, [00:27:00] uh, Alliant estimates the project will save customers about $450 million over the 35 years by avoiding volatile fuel costs and.

We’ll generate more than $100 million in local tax revenue. Now, Joel, I think everybody in Europe, when I talk to them ask me the the same thing. Is there anything happening onshore in the US for wind? And the answer is yes all the time. Onshore wind may not be as prolific as it was a a year or two ago, but there’s still a lot of new projects, big projects going to happen here.

Joel Saxum: Yeah. If you’ve been following the news here with Alliant Energy, and Alliant operates in that kind of Iowa, Minnesota, Wisconsin, Illinois, that upper. Part of the Midwest, if you have watched a or listened to Alliant in the news lately, they recently signed a letter of intent for one gigawatt worth of turbines from Nordex.[00:28:00]

And, uh, before the episode here, we’re doing a little digging to try to figure out what they’re gonna do with this wind farm. And if you start doing some math, you see 277 megawatts, only 40 turbines. Well, that means that they’ve gotta be big, right? We’re looking at six plus megawatt turbines here, and I did a little bit deeper digging, um, in the Wisconsin Public Service Commission’s paperwork.

Uh, the docket for this wind farm explicitly says they will be nordex turbines. So to me, that speaks to an N 1 63 possibly going up. Um, and that goes along too. Earlier in the episode we talked about should you use larger turbines and less of them. I think that that’s a way to appease local landowners.

That’s my opinion. I don’t know if that’s the, you know, landman style sales tactic they used publicly, but to only put 40 wind turbines out. Whereas in the past, a 280 megawatt wind farm would’ve been a hundred hundred, [00:29:00]20, 140 turbine farm. I think that’s a lot easier to swallow as a, as a, as a local public.

Right. But to what you said, Alan. Yeah, absolutely. When farms are going forward, this one’s gonna be in central Wisconsin, not too far from Wisconsin Dells, if you know where that is and, uh, you know, the, the math works out. Alliant is, uh, a hell of a developer. They’ve been doing a lot of big things for a lot of long, long time, and, uh, they’re moving into Wisconsin here on this one.

Allen Hall: What are gonna be some of the challenges, Yolanda being up in Wisconsin because it does get really cold and others. Icing systems that need to be a applied to these blades because of the cold and the snow. As Joel mentioned, there’s always like 4, 5, 6 meters of snow in Wisconsin during January, February.

That’s not an easy environment for a blade or or turbine to operate in.

Yolanda Padron: I think they definitely will. Um, I’m. Not as well versed as Rosie as [00:30:00] in the Canadian and colder region icing practices. But I mean, something that’s great for, for people in Wisconsin is, is Canada who has a lot of wind resources and they, I mean, a lot of the things have been tried, tested, and true, right?

So it’s not like it’s a, it’s a novel technology in a novel place necessarily because. On the cold side, you have things that have been a lot worse, really close, and you have on the warm side, I mean just in Texas, everything’s a lot warmer than there. Um, I think something that’s really exciting for the landowners and the just in general there.

I know sometimes there’s agreements that have, you know, you get a percentage of the earnings depending on like how many. Megawatts are generated on your land or something. So that will be so great for that community to be able [00:31:00] to, I mean, you have bigger turbines on your land, so you have probably a lot more money coming into the community than just to, to alliance.

So that’s, that’s a really exciting thing to hear.

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.
