The Perfect Gift for Wind Industry Friends: “Where the Wind Takes You”
Allen and Joel chat with Alex Pucacco, an engineer in the wind industry, about his new book, “Where the Wind Takes You: Adventures of a Wind Turbine Engineer”. The book shares real-life stories and anecdotes from Alex’s 10+ years working as a wind turbine technician and engineer, set in the days of the “Wild West” in wind. It follows an apprentice wind tech named Aaron as he tries to get experience in the industry. Each chapter features trips to different wind farms around the world where Aaron encounters colorful characters and gets into humorous scrapes and mishaps while working on turbines. Tales of issues like missing tools, breaking down vehicles, and adventures at local hotels highlight the lifestyle of constantly traveling techs. If you’re looking for a holiday gift for your wind industry friends, this is it!

Allen Hall: Our guest is author Alex Pucacco. Alex is based in Nottingham, England, and is an engineer by training, working in the wind industry since 2011. Alex is the author of a brand new book about being a wind turbine technician and engineer. It’s called “Where the Wind Takes You: Adventures of a Wind Turbine Engineer”.
Alex, welcome to the program.
Alex Pucacco: Thanks for having me. Appreciate it.
Allen Hall: So there’s very few books about being a wind turbine technician or engineer in the field. Yours is interesting because it’s based on real life experiences. And I know you’ve changed the names to protect the innocent quote unquote, innocent, right?
It’s, but it’s really based upon on some level, your interactions and working in winds, you’ve been in wind over 10 years. And you went through some of the, what I would call early times in wind, when wind started to become big. And Scotland and it looks like most, mostly Scotland early on, at least some of the book is about that.
I want to hear some of the details, like how did you get into wind? Why did you get into wind? What was some of those early experiences because there’s a that at that time it was a difficult industry to get into.
Alex Pucacco: It was and I think it still is to a degree and as I would say it’s better to be lucky than smart. I did I wouldn’t say mine is a conventional route. And I think since releasing the book a lot of people have approached me to ask desperate to get into wind, what’s the best way? So I guess in repayment for that I have I’m putting together an article at the moment to help young people get into wind because it is very competitive and difficult despite us crying out for more technicians. So yeah, I did a engineering degree at the University of Nottingham, which was completely useless.
Didn’t pick up a spanner in the entire time. Graduated into a recession ended up working for a small UK manufacturer of off grid wind turbines, the tiny ones on the back of boats. Did a bit of residential solar for a bit, and then I went to California Wind Tech, which was like a two month course they did in California, just as an introduction to electrical and hydraulic schematic reading, and then I got a real lucky break.
I applied for a salesy operations job, which was a real sort of dog’s body type role. And they gave me a chance at a wind turbine gearbox consultancy that was just starting up in wind. A load of people had left on maternity leave. We didn’t have enough people. And, we had more work than we could deal with.
So very often there’d be a shout around the office, who wants to go to Australia, America, Scotland, to do whatever job it was, main bearing inspection, portable vibration demonstration, something like that. Stick my hand up. Yeah, I’ll go. Get yourself booked. You travel. Off you go. And that was it.
You were gone for two, three weeks. And it was fantastic. I was very lucky.
Joel Saxum: So this must have been before kids and wife, right?
Alex Pucacco: Yes, this was yeah, this was very much before B. C., as they say, before children. So I’ve got two young kids now. So those days of carefree travel without permission slips, signed, sealed and delivered very much before that time.
But I think that’s true of a lot of people’s experiences within wind is that especially if they work for OEMs, where they do a lot of travel, the story of the traveling technician is a very frequent one. And how they progress into sort of working at a particular wind farm or getting two feet across where they get employed by the wind farm owner.
So it’s a fairly familiar journey, and then they progress design manager, et cetera. So as I traveled around these places, visiting different wind farm site owners, lead technicians, everybody that worked in wind all over the world, I started getting talking to them, ask about their back story and usually you could get them go in telling stories quite easily and as somebody that get bored and there’s a lot of dead time and waiting around in wind as anybody knows.
Whether it’s for a boat or, for wind or weather or parts there’s loads of waiting. So you can usually get people talking and understandably quite a lot of the subject matter within the book, where the wind takes you is about going to the toilets and those idle hours. Spent talking absolute nonsense, pranks, getting into shenanigans, crashing pool cars, everything you would expect of unsupervised men alone, a hundred meters up in the air uh, ex squaddies, obviously they’ve got a very interesting approach to work great sense of humor.
So it’s. It’s a very male orientated book, I’m sorry to say, although there are female characters in it. But because of that, a lot of the humor is very male. So it’s very good value for that. There are 11 chapters in here, which are essentially each of them is a trip to a different wind farm in a different country.
And it follows the journey of Aaron, who is a wind turbine apprentice, him trying to get his feet on the rung of the of the wind industry. As he progresses, as he his way through every scenario because he doesn’t know what he’s doing. And just him desperately trying to blag any type of competence or perceived competence.
As he figures out what it is he’s supposed to be doing. And all the colourful characters that he meets in wind turbines, completely unsupervised and alone. It’s really his journey. But a lot of the stories, whilst the places are real, the people are real, it’s all based on my experience. A lot of the stories, especially the anecdotes, are borrowed.
They’re all true, 100 percent true. And I think that’s what I really enjoy about the book is that these are all real people. And I think that some of the best feedback I’ve had from either the people who have donated stories or the people who have read it, have they said it’s very true to form.
It’s relevant. It’s a representation of their life. And they can pick out not so much the people, because as we say, we’ve anonymized everybody to protect everyone. There’s still people, some of them in very senior corporate positions now that have contributed to this book. And and they’re all here and they’re all very recognizable.
Even if they don’t know the particular person, they will know someone like them, I would guess.
Allen Hall: It’s a real life look into wind industry of that time. And I think that’s what’s fascinating about it because it’s was difficult. Everything about it was difficult. Running around in a van, a couple of guys in a van with a bunch of tools into a muddy field or icy field climbing wind turbines turning over sheep that have flipped over in the field and yikes.
Alex Pucacco: It’s I mean it’s very easy to be unprepared because the nature of wind is very changeable. Anyway, when you couple that with the facts, you’re trying to maintain a turbine where all of the paperwork you’ve got is beg, borrowed, and steeled. The tooling is modified ad hoc, it’s, you have to be incredibly adaptable at the same time squeaky clean from a health and safety perspective and it’s completely impossible.
Allen Hall: Speaking of squeaky clean, a lot of the book is about everybody being dirty. Or greasy. Covered in mud. At that time, that’s what, that’s how it was. It was a very unregulated, so to speak, industry. Things needed to get done. So it took tough people to, to get it done. And that’s the thing that stands out about the book.
Alex Pucacco: Yeah, it is the wild west. I like, there are some stories in here which go all the way back to sorts of, the engineering hippie days of the late eighties where, lattice towers, everything else. So there are, even though most of the story is based on the two megawatt platform, the sort of early to 2010 3s, this type of thing. He’s, there’s a real span in there. And despite us having the wind turbine safety rules now and, we know better and everything’s in the spotlight. We have oil and gas and some very established financial players at the scene, especially in offshore.
It’s still the Wild West, what happens up tower still stays up tower, and there’s a very, there’s a very big gap between those that finance and those that maintain and I think the stories still keep coming. I was worried, especially now the introduction of turbine toilets into sort of some of the newer machines.
That’s the end of it. There’s no more good stories to come, but good to hear that even on the Hallye platform, absolutely covered, it’s got more CCTV in that 15 megawatt turbine than the City of London. Still no toilets. So it just means that when you are going to the toilet, you put your thumbs up to everybody at Marine Coordination who’s looking at it.
So it’s we’re still not learning our lesson, still reinventing the wheel. And I think that’s part of the fun of working in wind.
Joel Saxum: There’s a major difference that you see between the the shiny, clean exterior that, that the, is portrayed in branding or marketing or in the media or whatever, and what’s really happening.
If you look at a technician’s phone and his videos and stories and things that are going on there look at this one. Look, we were installing this tower before it had, the viv protection under something and the towers up there swinging them a meter per second. There’s guys holding on up there and stuff like, so there’s a lot of things that happen behind the scenes.
And I think the book dives into those stories and gives it gives a. Almost like a picture of what’s really happening under the hood of this vehicle out in the field.
Alex Pucacco: Yes, very much. And I think I think that’s where the most fun is had, I think as well as where the, as the old saying goes, if you want a clean paycheck, you need dirty hands.
And some of my stories are just the sheer silliness of it. And this story I’m about to tell isn’t actually in the book, but it’s it’s from a Siemens 2. 3. So it’s got these lovely sort of clamshell nacelle. Open roofs where you’ve got like it, so you’ve got a complete vista either way and what a couple of technicians did was that they worked it out, they measured it up and they strung up hammocks between the top of the clamshells.
And beautiful sunny day. So stripped off to their boxers. Lunchtime, they’re ahead in service. It’s a very slow day. So they’re lying there in the sunshine, reading a book. You’re drinking their cups of tea. And then one of them gets up and he sees the other guy’s
clothes and he just launches his clothes over the side of the clamshell. So he stood up there, just in his pants. So it, as a kind of act of revenge, the guy gets out of his hammock and he throws his mate’s clothes over the side as well. So they’re both standing there with their boxes and they’re laughing, obviously they’re just boys, they’re being silly.
And so they finished the day’s work, beautiful sunshine, 25 degrees, late eighties, American money. And they think okay, put their harnesses on. So they’ve got just their pants, they’ve got their harnesses on. So it looks like they’re wearing bondage and they climb, the climb down tower. And they step out into the field and they come across this border collie and they’re like, what’s he got in his mouth? So the border collie’s got this guy’s t shirt in his mouth. And this farmer comes out of nowhere and he’s Hey there. And they, and this farmer clocks these two semi naked blokes stepping out from the tower door and he just looks at them and he just shakes his head.
And the, it’s, as you say, it’s where else could you do that?
Allen Hall: For anybody that’s worked in wind, For any length of time, being in a car or a van or a truck is just part of that lifestyle because you spend so many hours in there. And that’s a great deal about the book. There’s two places where the technicians are spend a good bit of time.
In a vehicle stuck or trying to get a wounded vehicle back to the hotel. And then the second is the hotel that how many nights you spend away from home and the different crazy places you end up spending a hotel night. And UK hotels are a lot different than American hotels. There’s a lot. They are more integrated into the fun part of life is built into the hotel.
It’s not just a sleeping space. So it’s more of a relaxation space too. You want to talk to what those experiences were and how much time you actually spend in a car. Some of the adventures in those that happen in those places.
Alex Pucacco: Yeah, sure. Inevitably a huge part of the job is travel and in your twenties is fantastic because you’re partying around the world on the company dime, which, can you really put a price on that?
But in the UK, all of our wind farms, they’re fairly remote. It’s not like Texas or Australia where you’ve got fairly hubs, if you will, and lot larger populations as well. So you’re looking, you’re thinking rural Wales, rural Scotland, and some of the places that you stay have a lot of how we say character.
So usually there’s one person in the pub that does front desk. Cooks the meals, serves the drinks, turns the beds. And you’re there for two or three weeks stinking up the
place. And if, and if there’s two or three of you or six or 10 of you on a job, you descend and take over this whole establishment, like it’s your house for the week, basically.
And especially some of the more, shall we say, testosterone, and, the more blokes you get in one space, the more ridiculous it becomes. Because you’re always pitching to the lowest common denominator. I think that’s, a lot of it is about male camaraderie. Drinking far too much on a school nights.
Yeah, that type of thing. But yeah, the travel aspect as well cultural observations as somebody that had not seen much of the world before working in wind, uh, going to Australia and observing for the first time that no, actually the wind turbines do spin in the same direction. It’s still, still a wind turbine.
Desperately trying to walk and walk whilst not being able to talk the talk. And I think that’s what Most people enjoy is that everybody was new once and this is very much somebody that was just starting in wind. And we were not just within wind at the time, but the company that was working for as well.
We were making up as we went. And I just could not imagine doing that now, especially when you consider the size of the companies that operate these wind farms absolutely huge utilities. And you’ve got a bunch of chances just walking in and just but yeah I don’t know, I’d like to think we have matured and some of that stuff which happened then wouldn’t happen now, but yeah, it still happens definitely.
Allen Hall: The other thing that stood out was the number of times you’re looking for tools, particularly sockets, that there’s always a missing socket and you find tools in the most, in the weirdest places. We want to talk about some of those situations.
Alex Pucacco: Yeah, it’s the classic meme of the lost 10 mil socket, and I think Aaron actually finds one during one of the stories, which is just goes to show how lucky he is.
But yeah, misplaced tools. The main tool of my trade was was an endoscope, which was an incredibly unreliable piece of kits because they were supposed to be designed for more. Inspecting squeaky clean off the production line, Rolls Royce jet engines. We used to stick them in all the gearboxes and main bearings all the time.
And understandably they broke quite often. So you’d be left on the other side of the world with a very expensive, but broken bit of kit. And it happened a lot.
Allen Hall: Who has to deal with all the technician silliness that’s happening out on the wind turbines themselves. The people who manage these guys must have incredible stories. And just probably just wait for the telephone to ring.
Alex Pucacco: I’ll tell you what, they have some of the hardest jobs. It makes me very thankful that I don’t work in operations and maintenance anymore because it’s like having a second family. Like you have uh, one of the stories is about a site manager in in Illinois somewhere.
He has a hundred and something plus turbines and a similar number of landowners on the cornfields. Farmers that, that own the land and therefore get a bit of a kickback from the turbines. And it talks about his relationship with his many bosses that he has, these sort of slap jawed farmers that sort of complain when his turbine’s down or it’s being maintained or something like this.
And he doesn’t really need to look at SCADA because his phone will ring and the farmer will tell him that the turbine is off. So it’s and a lot of the best site managers used to be technicians. And because of that, they know exactly what the techs are up to. They know when they’re taking the pace when they’re taking too long on changing the brushes or inspecting the filters or whatever is the task that they’ve been given.
And they are the kind of teenagers amongst toddlers really is the best way I could describe it is that they, they have to give the appearance of maturity, but really, they’re the earliest opportunity that, hats on their up tower as quickly as possible. And the best site managers always used to be technicians, but at the same time, they’ve also got to wear half wear the corporate hat and do the reporting and everything else. But, very easy to draw them into storytelling mode. And especially when I was driving around America doing quite a lot of sales and main bearing inspections and stuff, very easily, you could draw people into storytelling mode.
And I think that’s, I was quite lucky that Especially seeing how America operates window and I’m compared to the UK where we have. denser population, smaller turbines, smaller wind farms as well. And you’d be driving through a wind farm in Texas and you’d just hear this dung. But there’s nobody around to hear this wind turbine that’s got two teeth missing on the IMS.
And you’re like it doesn’t really matter because, you don’t need condition monitoring. Just drive around with the truck window open and you can see which one’s hanging. And, that’s just Texas. The whole, yeah, the earth smells of oil. There’s nobody around to hear it.
And when in an agronomic regulated market, the price of power drops to 17 a megawatt, unsurprisingly, you’ve not got gearbox, so that’s how it runs. And just to see, something that’s come from the UK, especially offshore where everything is, downtime is expensive. Boats are expensive.
Power is king. And because of that, damn the cost of everything to go to the U S where it’s just yeah, just keep it running, give it a go. Probably just needs a lick of oil, slap it. It’s good to go. It’s interesting to see how. depending on the market drivers, the turbines, the wind farms, how different countries operate.
And that’s, again, that’s another piece of insight that the book provides as well. But, uh, there, there’s pictures in here as well. Some of them based on my own photographs, others, which are borrowed really if. It’s coming up to Christmas time now, if there are if you have somebody in your family that reads Daily Telegraph and still calls them windmills, it might be a quite nice little eye opener for them.
If, they can actually talk to you about your job rather than just asking the usual sort of, uh, benign questions of feigned curiosity. So it’s fairly accessible, anybody that’s either worked as a technician or if they have a white collar job now, or if they want to reminisce about when they used to have to get their hands dirty. Or indeed, one thing I would suggest, though, don’t give it to your kid if they’re young, because it’s fairly it’s 18 plus. So a couple of people have asked me that it’s not really age appropriate, as well as the representation of how what it’s like to be a female engineer within wind as well, which is compared to other industries, I think we’re pretty awful at in terms of representation.
So that’s touched on as well. So there’s lots of themes, something for everybody. But it’s very light. It’s a very easy read and it’s hubris. So it’s not that serious.
Joel Saxum: So where can people get the book, Alex? What’s the easiest way to buy it?
Alex Pucacco: There’s two options. So the book is in aid of Mental Health Charity.
So this was written for MindUK and it’s really to support young people into help building their confidence, overcoming issues of anxiety, depression, anything really that’s going to, prevent them experiencing and enjoying life. From a mental health perspective, if you want to support mental health charities, it’s available through my websites, which is windyproductions.com
if you go to the book section it’s within there and if you are less bothered or if you want something a bit more accessible, it’s also available through Amazon as well. So “Where the Wind Takes You” is the name of the book and “Adventures of a Wind Turbine Engineer” is the subtitle. Please do buy it on there.
Leave a review if you like, and please do enjoy, give it to your friends family.
Allen Hall: So “Where the Wind Takes You” is just full of unfiltered, true to life stories about the wind industry, and it’s a great gift for the wind technician or engineer in your life. And honestly, how many times can you gift a Lego wind turbine?
This is something different for the holidays. yoU can go on Amazon, go on Alex’s website and order the book because it is a really good read and it does give a lot of great insights about the wind industry. So Alex, this has been fantastic.
The Perfect Gift for Wind Industry Friends: “Where the Wind Takes You”
There is a mountain of physical evidence that the Earth is far more than 6000 years old, despite what we’re told in the bible. For one, we have the carbon-dating of dinosaur bones that have been around for hundreds of millions of years.
Some people invoke the theory of “satanic interference” to explain this. That is, the devil himself plants these fossils for us to find, in an attempt to discredit the true word of God.
To me, that’s a stretch, but it’s not too different from what Mike Johnson says here about voter fraud. He even uses the word “diabolical.”

Allen Hall: The Uptime Wind Energy podcast, brought to you by StrikeTape. Protecting thousands of wind turbines from lightning damage worldwide. Visit StrikeTape.com. And now your hosts
Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall. I’m here with Rosemary Barnes, Matthew Stead, and Yolanda Padron. And three out of the four of us, everyone except Rosie, went to Houston this past week. Matthew, you were on the floor. Yolanda, you were on the floor this week. What did you think?
Matthew Stead: I think there was a few sort of common themes that I picked up. One, the obvious one which keeps coming up every time is insurance and lightning, and insurance, and all those sort of things. probably the other point that I observed was really strong supply chain. they had everyone, all the people, e- even people, building boxes.
And [00:01:00] so they had boxes, transportation, cranes, really strong, supply chain. also really strong on the batteries, like the CATL batteries, et cetera, et cetera, and solar. I think that seems to be getting a bit more, a bit more, mature and more obvious. obviously blades, lots of people talk to us about blades, maybe ’cause we talk about blades.
But, lightning root issues, blade bolts, those sorts of things, leading edge erosion, robotic repair, et cetera, et cetera. a bit about, add-ons like PowerCurve, were fairly visible, so that was good. but there was a lot of secret meetings in rooms away from the actual event.
so that was one observation. and the other observation was perhaps not so many operators that actually [00:02:00] work on a day-to-day basis. That was my subjective impression
Rosemary Barnes: Speaking of secret meetings in rooms, what were you guys doing around the time of ACP?
Matthew Stead: So the Australian American Chamber of Commerce organized a special event, with two Australian companies to launch a new product, which monitors lightning and then transmits the results using satellite communications.
So it was very open, but invitation only, Rose.
Rosemary Barnes: I, actually, I- the comments, ’cause people are always, after our first go organizing wind O&M event in Australia, I would hear about it from people who didn’t, just chatting at, on, different wind farm sites. They didn’t know I was involved, and they’re like, “Oh, yeah, there’s a secret event now.”
And it’s we did our very best to publicize this, the most that we could. It was not intended to be secret. So yeah, I’m just wondering if, people are gonna think the same if [00:03:00] they, they missed out on, your event. But how was it re- received? Do, we need more events in the US?
Matthew Stead: Yes, absolutely.
And I, I don’t have my pin on here, but, yeah, I do have a pin from the Australian American Chamber of Commerce Texas division,
Rosemary Barnes: How was the event for you, Yolanda?
Yolanda Padron: It was good. It was good. the showroom was the, or the exhibit floor was a little bit em- more empty than I thought it would be, but it was good.
It was good to, to see people, to catch up with everybody. There were some really good chats happening everywhere. and I got … I don’t know about you guys, but I saw a lot more people not from the US that wanted to come in and understand the market better than I did other years, which was nice to see.
Matthew Stead: Was there any new technology on the floor this year? I thought there was a new robot company, but it was actually solar cleaning.
Yolanda Padron: I saw some rebranding from some companies, moving from former ties to [00:04:00] OEMs just m- moving into their own little companies and stuff. in a very interesting, PR move, a, an insurance company was raffling a motorcycle, which was really, funny for us to see.
Allen Hall: Not very safe, is it?
Yolanda Padron: Was
Rosemary Barnes: it at least an l- an electric
Yolanda Padron: motorbike?
Allen Hall: Rosemary, you’re in America.
Yolanda Padron: I don’t know very much about bikes, but it was big and scary for me. did I put my name in there? Yes. We’ll see how that turns out, but
Rosemary Barnes: I’m always trying to win Lego sets at, events and, try to sweet talk the, the stall managers or s- stall minders into “Oh, if somebody wins and they don’t show up, could I have it?”
yeah, so far unsuccessfully. Although I do have, actually you can see I’ve, I’ve got a Le- a L- Lego, in inverted commas, not Lego TM, wind turbine that we’ve just started making. So that’s a, [00:05:00] or a tower for a… that we have created. I have succeeded in getting some sort of Lego for my podcast background.
Allen Hall: Are you gonna buy the Sagrada Família Lego set that just appeared?
Rosemary Barnes: I haven’t. I’m not like the hugest Lego fan. I wouldn’t call myself an, what is it? AF- AFOL, adult fan of Lego? Is that what, There’s a, there’s an acronym. I’m not one. None of us are apparently.
Allen Hall: Oh, I don’t know. I think we’ll buy that one.
Allen, does it take 200 years to make? Probably. I think there’s around 10,000 pieces. that’s what I re- recall. It, there’s a lot of pieces. It’s built in sections. I watched had a little discussion about it. It is really complex, but we may purchase one and put it in the lobby of our shop because that cathedral is protected by strike tape, some of the ornamental features at the top.
So we’ll, probably build one, but it’ll, it will take a year
[00:06:00] Delamination and bondline failures in blades are difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production. CIC NDT are specialists to detect these critical flaws before they become expensive burdens. Their nondestructive test technology penetrates deep into blade materials to find voids and cracks traditional inspections completely miss.
CIC NDT maps every critical defect, delivers actionable reports, and provides support to get your blades back in service. So visit cicndt.com because catching blade problems early will save you millions
Let’s talk about American Clean Power’s, first quarter 2026 market report. So the American Clean Power Association’s first quarter 2026 market report shows United States developers brought 6.4 gigawatts [00:07:00] of new clean power online in Q1, but overall capacity was down 17% year over year, the weakest quarter since 2023.
Onshore wind took the hardest hit with less than 500 megawatts installed, the slowest pace since about 2018. the Department of Defense delayed approximately, 165 projects totaling 30 gigawatts and $54 billion of investment. Ken Young, the CEO of Apex Clean Energy, put it plainly, quote, “This DoD thing is real.
They found a button to hit, and we got punched in the face.” Unquote. Developers won a preliminary injunction in Massachusetts federal court, but the Interior Department has pledged to appeal in regards to offshore wind. Is this gonna be a permanent setback, Matthew? You think this is gonna continue on, or will this eventually get wrapped up and wind will be back on track?
Matthew Stead: If I wanted cheap power, I would be building wind, [00:08:00]battery, and solar. So I think, if people want cheap power, it, will definitely come back. That’s my view.
Allen Hall: Yolanda, you see some of the development. You’re close to it in Austin, Texas. What are you seeing on the ground there? I think there’s repowering going on, but is there much in terms of new development?
Yolanda Padron: There’s repowering. I think new development slowed down a little bit than this time last year, but it’s still going on, both for wind, solar, and battery, which is good. on the ground level in some of these very rural towns, this is a very important source of income for a lot of those people, regardless of political affiliation.
so it’s important for some of these people to get these on their, in their land.
Allen Hall: Does American Clean Power have a plan to try to address this situation? Are there any lawsuits in place or any legal action on the docket?
Yolanda Padron: Not that I know of. I, know there was a, there was that lawsuit end of last year, for offshore.[00:09:00]
but from American Clean Power itself, I don’t know of anything off the top of my head. Do you guys know?
Allen Hall: I haven’t seen much of a roadmap from American Clean Power on this particular issue on the onshore wind. I haven’t seen much e-except but for a couple of summary pieces explaining what is happening on the ground, but n-no action to push back.
And maybe there’s some lobbying going on with Congress people and, senators, but you think we would hear about some of it. I haven’t heard anything, and I’m watching pretty close. it is a little confounding because it does seem like this could be broken with one court case. Maybe not. Maybe it’s more difficult than that.
Yolanda Padron: I don’t know. There’s always a lot of, yeah, there’s always a lot of lobbying going on by, not just by American Clean Power, but by a lot of these larger owners, right? A lot of them have some sort of office in DC
and people coming in and out and going to meetings [00:10:00] with everybody, So I don’t know. I’m also very curious to see what goes behind the scenes for that political side of things.
Allen Hall: just as a quick aside, one of the discussions I was having during the week was about AI data centers and the push for power.
If gas turbines aren’t available for a couple of years and they’re gonna… the administration’s gonna push back on renewables, AI data centers are gonna have a hard time getting the power they need. I know the administration wants them to, be powered by natural gas, but that’s not possible right now. I don’t see how this ends easily.
Rosemary Barnes: It seems like e- everybody’s looking into any single way that you can power a data center. There are people making serious plans to do it. There’s obviously, we’ve talked about space-based data centers before. then there was a podcast I listened to this week. Allen, you actually suggested it to me, but it’s one that comes up for me anyway, Catalyst podcast about, [00:11:00] data centers on ships.
It, actually isn’t just purely about data centers on ships. It’s about, this company, and they have a ship that’s designed to fairly passively capture energy from waves of a ship out on the o- open ocean. They’ve actually designed the shape of the hull so that it is, will actually capture energy.
They choose the location of their factories very carefully, put it in the ocean where there’s already enough energy, and it just, phew, off it goes, just powers itself off to the, I think it was somewhere in the South Pacific, where there’s nice big fetches of, of water and power whatever, including data centers.
But I think each ship was about a megawatt or something like that, so you’ll need a lot of them. And then wasn’t there one that you were, you wanted to bring up today, Allen, an, underwater data center?
Allen Hall: The one that I think you’re talking about is Penthalassa, which has recently come out of the dark mode, and they have been working on this, in at least a couple of years from far as I can tell, [00:12:00] trying to develop data centers that…
using a, system driven by not necessarily the waves. It’s not the waves, Rosemary. I think it’s more to do with the pressure, of the ocean. It’s, something to that effect, which is really interesting. but, China has, like in many things, working offshore and trying to get data centers up and running.
they’ve commissioned the first undersea data center powered directly by offshore wind. The Shanghai Lingang project, built by a subsidiary of China Communications Construction, CCC, began operations off Shanghai’s eastern coast in May. Planned capacity is 24 megawatts, and the core design transmits offshore wind power directly to submerged data modules via subsea photoelectric composite cables.
I’m not sure what that is, but I’ll have to dig into that deeper. And by bypassing grid routing entirely. Seawater obviously will serve as the cooling medium [00:13:00] through circulating pipes in the heat exchangers, reducing electricity consumption by about 20%. one of the local v- university professors estimates that this kind of data center model could save about 50 billion kilowatt hours annually across China’s data center fleet, equivaling, equivalent to not burning 15 million metric tons of coal per year, and that would be nice.
Is there a future in offshore data centers that use the ocean to cool themselves and Plug ’em into wind turbines offshore, just get the electricity straight from the wind. Does this have growth futures,
Matthew Stead: particularly in China? I love it. I think it’s absolutely fantastic, and it just means you don’t have to send them into space, because that’s a silly idea.
The other point, do you remember a couple of years ago they were going to build, hydrogen electrolyzers, offshore n- next to wind turbines? So all they do is [00:14:00] just scrap the electrolyzer and then put in the data center. It’s just perfect.
Rosemary Barnes: But that’s what this, ship one that I was, I listened to the podcast of, that’s their, thing.
It’s just power for whatever. whatever, obviously it has to be something that’s capable of, operating on a ship environment. You’re not gonna be doing probably precision manufacturing or anything out there. But, apparently failure rates for, data center stuff is not…
They’re not expecting it to be higher. Higher in some types of failures will be higher, and some will be lower, but, they think that overall it’s so much, so much cheaper. But yeah, they did also talk about doing, yeah, I don’t know, hydrogen. Is anybody, is anyone still talking about hydrogen anymore?
I feel like we’re finally, not n- not doing that.
Allen Hall: Rosie, I think you killed it. I’ve seen more news reports about it, where they’re not proceeding and there’s been some funding challenges, and those things are happening. Like any new technology, it’s, hard. The beginning is hard.
Rosemary Barnes: But, you know that, already hyd- making [00:15:00]hydrogen the way that we make it today is something like 2% of the world’s, emissions.
So it’s okay, we do need heaps of clean hydrogen for that 2%. So I’m definitely not against, some hydrogen projects happening, ’cause we’ve gotta… That’s the, same size as y- you know, nearly as much as aviation, for example. so not insignificant.
Matthew Stead: Yeah, someone actually came up to us and s- I had a bit of a discussion about that, Rosie.
We’ve got a bit of information to share with you about that-
Rosemary Barnes: Oh, yeah …
Matthew Stead: that will dispute some of your claims. we’ll share that with you
Rosemary Barnes: offline. They’re not my claims. I’m merely reporting what people who are working on it say. But I, was saying to Allen, ’cause we had a big chat offline about contrails and how challenging it is to just alter an aircraft’s path to reduce them, I need to, Engineering with Rosie video on this and get an expert on and ask them all of Allen’s very informed questions.
maybe I’ll get you on as a co- co-interviewer. I’m actually keen on viewer input, listener input. we’ve got a, Pardalote actually has a training course [00:16:00]coming up. I’ve been trying to organize this training so that I and my employees can learn more about blade repairs. So we have a course coming up, organizing it in collaboration with Direct Wind Services.
We’ve got a great, blade repair guy who’s gonna be taking the course- It’s gonna start out with an optional day that I’ll be running about blade design, manufacturing, certification, those sorts of things. And then three days on blade repair. So we’ll go through the theory, also, hands-on stuff.
So we’ll be doing grinding, we’ll be doing layups, infusions, all that sort of thing for three days in Ballarat. but the extra cool part is that I’m gonna be using this opportunity to make a video about wind turbine blade repairs, ’cause, one, I’ve been si- trying, I’ve wanted to make a video on this ever since I started my YouTube channel, six years ago.
So this is the opportunity that I can take to, talk about what kinds of repairs are actually done. I think people will be really surprised to see, even in, when they’re brand new out of the factory, they still gotta do, dozens of repairs on a [00:17:00] blade before it’s ready to go out.
And people will also probably be surprised at, the extent of, repair that you can do and get a blade back up to its original design intent. So I would ask, anyone listening to this that has questions about those sorts of topics, let me know, and I’ll try my best to include that in the video.
‘Cause I think it’s a topic that’s not, super well understood.
Matthew Stead: Can I come along as well?
Rosemary Barnes: Nice, nice segue into me advertising. So this is our first one. We’ve got, we’ve got a few spots. I think that they’re gonna very easily fill, but we are planning to run them periodically. So yeah, you can get in touch and, let me know.
yeah. Anybody. You, Matt, I’ll send you over the, the information.
Yolanda Padron: That’s a really good idea, Rosie, ’cause I feel like a lot of people, you either have, a really robust, understanding of blades and a really good background on it, or you’re starting fresh. And when you’re starting fresh, it’s really difficult to know what exactly you’re [00:18:00] doing.
Or you know in theory, not until you go into the nitty-gritty or until you watch Rosie’s videos, do you then get a better understanding of everything that’s going on.
Rosemary Barnes: Yeah. It’s, a fascinating topic. obviously that’s what I spend 90, 90%-plus of my time working on. yeah.
Blade damage and blade repairs. But there’s so much, there’s so much information that would be better off if it was shared, if everybody, knew a bit more about what, what was possible, what was normal, what’s best practice. Then I think that the, O&M for blades would go a lot more smoothly.
Allen Hall: We had Matt Sagala on the podcast this past week, and one of the items he was talking about, some of the basic fundamentals of repairs, the little checkpoints that need to be in place when you’re looking at a repair, and the photographs that come in a repair report and some of the details, how they get skipped.
And there should be more emphasis on some of the basics, and making sure that the photos show the different layers that have been ground, where each of the plies are. [00:19:00] Something simple like that, which in a lot of good blade reports. You don’t necessarily see in all of them and Rosie, if you’re training people up and showing them what the fundamentals are, that’d be really helpful in getting that information out where you can access- where it’s accessible, like on YouTube.
Rosemary Barnes: I’m always giving that, that feedback back, “Can you please at least show, an image of what it looked like before you started repairing?” Nobody ever does that, and it’s y- we have the inspection, the drone image, but, you don’t have… you had, you were right there. You had the opportunity to take the , photo from every, angle, because you wanna be able to recognize what does this damage look like the next time that we see it.
What’s it gonna look like in a drone image? And, yeah, be able to… sometimes you get in there and you think that you’re just gonna be repairing a couple of layers, and it turns out to a huge, thing. like I’ve seen repair , repairs come in that, hundreds of thousands or more, to do just one repair that was totally unexpected by the person who was paying the bill.[00:20:00]
the more information that you take about that repair, then the more possible it is for engineers like me to be able to, a- at least predict, okay, you’ve, you’re likely to have a big repair here, and plan for it.
Allen Hall: Trying to find someone doing blade repair correctly on YouTube is hard to find.
It really is. I s- you see people with grinders and things, and yeah, they’re working hard and they’re doing a job. But someone to actually walk through from beginning to end, and made it, and explained it as they did it, would be helpful to the industry. Tremendously helpful.
Yolanda Padron: Just to make sure that your budget’s right, for the year.
if you’re on the owner’s side, and then you think, “Oh, okay. Sure. this AI-based drone inspection told me that I need to tackle all of these, and I know that these are gonna cost me, I don’t know, X amount of dollars,” you can, take a, human pass through those images and make sure that, your expectations and your reality is, closer, just by [00:21:00] looking at Rosie’s videos.
So that’ll be, really exciting.
Allen Hall: Rosemary, how do people join in on your blade repair fun?
Rosemary Barnes: for, first of all, get in touch if you wanna do the course, especially in Australia. we could definitely organize one. In, the US coming up, piggyback off a- another event or somewhere else.
But also get in touch with me at pardaloteconsulting.com, and you can, yeah, send me a message through the contact form and let me know that you’re interested. Maybe spell pardalote,
Yolanda Padron: though, for people.
Rosemary Barnes: Pardaloteconsulting.com. P-A-R-D-A-L-O-T-E and then consulting.
Allen Hall: As wind energy professionals, staying informed is crucial, and let’s face it, difficult.
That’s why the Uptime Podcast recommends PES Wind Magazine. PES 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 [00:22:00] content you need. Don’t miss out.
Visit peswind.com today. in this quarter’s PES Wind magazine, which you can get at peswind.com, there’s an article from Minerva Energy, ABJ Renewables, and Concept X where they have developed a product called WindView, which is an advanced inspection system using high-res optical capture with thermographic analysis for a full subsurface, inspection from rotor to tip.
the system detects defects as small as three to four millimeters, which is quite small, and a- analyzes the blade structures up to about 15 centimeters, which is quite deep, so that it does seem like a pretty useful inspection tool. as we all know, just the generic, visual drone inspection can give you an idea of what’s happening on the surface, but a lot of the structural issues are deeper [00:23:00]inside the blade, so thermal inspection combined with optical inspection can give insights into some places that otherwise go unseen.
And Rosemary, as a blade expert, and Yolanda too, there’s a lot that happens inside of blades, and having a- an additional tool to inspect blades and to get more understanding of what’s happening underneath the paint service could be really useful.
Rosemary Barnes: Yeah, I’m always trying to recommend th- this. I haven’t got any clients that have actually used thermal imaging, to look for damages, but especially in, areas where you suspect that there are r- some repairs that haven’t been done correctly or you’re looking for early signs of a serial defect.
Y- like one of the weird things with the full service agreement, actually it’s probably true with, yeah, any kind of turbine sale, is there’s this serial defect liability period, and you’ve got to hit usually, a crazy high, stupid high number, like 20%, 30% of all your blades have to have the [00:24:00] same damage within it might be a two or three-year period, not, very long.
It’s better when it’s more like 20% in five years. That’s, enough time to actually catch things. But so one of the things that you’ve got to do is like you really want to catch things early in order to be able to, y- make a claim on that. And so this is one of the tools that people would have to catch things earlier, like it’s not yet visible, with a crack on the surface that– Or even, like even small cracks on the surface will fly under the radar as well because, they won’t be flagged in the inspection reports.
So if you’ve got a few of something that’s looks like it might be the same, it, and you’re still within your defect, your serial defect liability period, it’s definitely worth doing something, the, some kind of NDT, and this, is one of the good options it’s actually worth spending a whole lot of money to, to try and get that in because, like the numbers are, millions and millions of dollars, maybe tens, maybe hundreds, depending on, the extent of the problem.
So yeah, it’s always good [00:25:00] to be well aware of what your deadlines are and what tools are available, and this is one of the good ones.
Allen Hall: Yolanda, you think it’ll open up access to carbon pultrusion inspections on blades without actually cracking the blade open?
Yolanda Padron: Hopefully, yeah. in, internal inspections you can only go so far, right?
And Rosie, you have a lot more experience with this in action than I do. but yeah, so I, I think it’d be really interesting to see just what, what people can get done without actually happing- having to go and carving everything out, and without having to already start a s- a, a repair that maybe you don’t have the budget to do.
Allen Hall: If its speed is fast enough, I- thermal imaging can be slow at times, but from what I’ve seen, the, cameras have really improved over the last couple of years. If they have this down where you could really inspect blades quickly, it would be a tremendous help to have insights into [00:26:00] depth of damage, especially with c- I think carbon pultrusions are the one that we just don’t have a lot of oversight with, and it’s very difficult to inspect.
And so if you could actually see damage to the pultrusion ahead of time, that would be a, major advantage. I, can’t imagine the insurance companies wouldn’t love this system. S-
Matthew Stead: it’s interesting. Yeah, I’ve got a question. GE Vernova has a patent around some of this, technology. They’ve had it obviously for many years.
But, I know one of the challenges with the GE Vernova approach was that through the day, if you’ve got ambient temperatures, it was a bit hard to pick up, the actual damage. So at least for the GE, solution, it had to be done at dusk or, when the sun wasn’t out. So I don’t know the answer to that, but is that one of the technical challenges around, when it can actually be taken?
Do you need to take it when the sun’s not out?
Allen Hall: Yeah, I wonder that too I’ve– The way I’ve seen it is they try to catch it at sunrise or sunset where there’s [00:27:00] a thermal gradient on the blade. However, the thermal imaging cameras is, are, cameras are so much better than they used to be. it may be possible to just do it during the daytime.
Rosemary Barnes: I think the different companies are approaching it in different ways and, I’m sure that some of them can do it, like especially under direct sunlight, then that can be actually a really good way to get some, some heating. And then g- it relies– Mostly it’s relying on the fact that different materials heat up at different rates.
So as long as you’ve got some sort of change in, in temperature happening, then you should be able to see. Yeah, like obviously if there’s a big, crack or a delamination, there’s some air there that’s gonna heat up differently than the composite around it.
Allen Hall: Oh, sure. Yeah.
Rosemary Barnes: Yeah. I think also like when cracks propagate, they are actually generating some heat at that site and you, can catch that too.
But, I’m, actually not on top of it enough to know how much it’s one or the other. I think it’s mostly about, when a blade heats up, air will heat up differently to, to composite and you’ll be able to see it. that’s my limited [00:28:00] understanding anyway. Something worth more of a deep dive.
I’m actually looking forward to some, hopefully some clients getting over the line to, doing some more of the, taking advantage of some of the NDT tests that are, available because it can just help you do such a better job of, management and huge risk redus- reductions too.

Lev Parnas is Soviet-born, and thus he may not know that we can’t disallow Trump’s lifelong degradation of women.
But we can stop electing the most disgusting human beings on the planet to lead the United States of America.
It’s also worth mentioning that, astonishingly, many American women don’t have a problem being kicked in the teeth by Trump; he got 45% of the female vote in 2024.
