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

Allen Hall: Ed0o and Soren, welcome to the program.

Edo Kuipers: Thank you very much.

Thank you both.

Allen Hall: We have some really exciting news from you, from the field, but first I, I want to start with the problem, which. A lot of operators have right now, which is this blade root, bushing it in or insert issue, which is really critical to blades and you’re the creator of the device that’s gonna save a lot of blades.

You want to talk about what happens? When these blade root bushings fail?

Edo Kuipers: Uh, yeah. What we have seen is that it especially concerns, um, uh, polyester type of blades. And what we see is that, um, bushings and, and, and composites, they are not attached to each other anymore. And after a [00:01:00] while, blades are simply flying off.

That’s the, that’s the whole, that’s the whole problem. Of course. And now going back to the root cause, the root cause here is we are working with, with foes and. The fact is that if you’re working with polyesters, they already have, um, at the, uh, uh, during the process, the curing process, they have already curing shrinkages.

So we have already curing shrinkages, which means we have already initial micro flagging going on, on the interface between the bushing and, and, and, and the limited around it. And that reduces, that reduces the um, surface. Carrying area. And by doing so, because we have less area, surface area that can transfer the loads from the hub, um, from the blades to the hub, eh, we have limited amount of, of years on running.

So we are reducing, uh, the, the amount of years [00:02:00] that the blades are on the, on the, on the turbine safely.

Joel Saxum: This problem is compounding right now simply because there’s a lot of the global wind turbine fleet that’s starting to age. Right. Like we, we, we went through a big push in, you know, the early two thousands, 2000 tens, 2000 twenties to now where, you know, if you look at the country of Spain, we hear that regularly, Alan is, Hey, we’re getting to the end of life.

We’re close to the end of life. Then there’s people saying, what is the remaining useful life? Where are we at? Um, and this is one of those issues where. It can develop rapidly, right? So if there’s an issue, you can, if you catch it in time, great. You’re good. But it can develop rapidly and that can lead to catastrophic losses.

But I guess my, one of the questions I want to ask you, and you guys of course have done some commercial here. Uh, how many turbines do you think are affected by this globally affected by this root bushing issues?

Edo Kuipers: Oh, that’s a good one. If I, if I talk a number of blades at the moment, we are more or less at a ball point figure about 30, [00:03:00] 40,000.

Blades. Wow. Worldwide. So we see many us, we see many in South America and we see also in Southeast Asia, like India. And those blades are running, let’s say from 10 years, 12 years, and some of them also after six years,

Allen Hall: and a lot of manufacturing. Uh, blades happens in multiple sites, right? So if you have a particular OEM wind turbine, you may have a variety of different blades on your site.

You typically do. Some of them are polyesters, some of them may be epoxy, but it’s the polyester ones we need to pay attention to first, right?

Edo Kuipers: Correct. The one we are, uh, concentrating on with our solution are dealing with polyester blades because there we see the problem, especially in the, in the interface layer.

There are also root problems with epoxy types, but they are from a, from a different level.

Allen Hall: So the thing that we’re looking for when we start to see [00:04:00]the problem, so if I’m an operator and I have technicians out in the field and they’re looking at blades from the ground, typically very quickly, what are the first signs that you have problems with the bushings?

Edo Kuipers: What we generally see, the first signs is that there is a cracking going on in the ceiling, which is between the blade. The pitch bearing. So if you go up tower as a surface guy, then then look for those initial cracks, and if you see cracking, cracking in that sealant, then remove the sealant just by with a knife and, and, and go with a fill gauge to see if you’re caping going on between the root lum.

Uh, so between the bushing and the, and the, and the pitch bearing,

Allen Hall: so that sealant or gasket between the blade and the pitch bearing shouldn’t be moving or shouldn’t have flexed it. It shouldn’t have broken. It can flex. It’s made to flex a little bit, but if it breaks, it tells you there’s too much stress [00:05:00] on that sealant.

That’s really the first sign.

Edo Kuipers: That’s really the first sign. Then you still have time, but then you have to start monitoring

Allen Hall: and the, the monitoring is telling you what,

Edo Kuipers: once you. Notice this. What you have to do is, for example, you are positioning a leading edge, uh, under the tensile loading of the dead weight.

Then you measure a cap, then you pitch the blade, eh, that the, that, the, that the, that, that side is down. So it’s, it’s, it’s feeling a compressive loading, and then you can see if there is a difference. So what you’re doing is you’re measuring the variable cap. That’s a static gap, but the variation of the capping due to the, due to its own weight of the blade, and that is a sign that that movement is going on.

Allen Hall: So you’ll see compression versus tension, that gap get larger and smaller. There is always some movement in that gap, but it’s very limited if you, what typically is a threshold where you say. [00:06:00] If it’s beyond a couple of millimeters, that’s a problem. Where is that dimensional gap become an issue

Edo Kuipers: with our present customers?

We are saying, um, um, one millimeter and you have to hoist, uh, hoist the blade down.

Allen Hall: One millimeter is 40 thousandths of an inch. That’s not very much.

Edo Kuipers: If it’s, for example, five millimeters, I mean. It’s, it’s not, you’re in a, in a bad stage that within three months your, your blood, your blade could fly off.

And if you are in, in the range of one millimeter, the nice thing on that is that you have a limited amount of bushings, which needs to be replaced. So you are li limiting the effect of the repair.

Joel Saxum: So, but that’s the big thing here, right? So catching it early, it’s like anything in blades, we talk about this.

We’ve been, we’ve been beating this, this horse for a long time. Catch it early, fix it early, or you’re gonna be in a bad state. Because I mean, the, the, the worst thing that happens here, of course is the safety issue, loss of life or anything like that. But what? But the, [00:07:00] what We have seen blade breaks, blade comes down, hits the tower.

Then the tower comes down, then you’re replacing an entire turbine. And that’s, that’s horrible for the operator, the industry, everything in, in, in general. Um, but if you catch it early, now each blade has de, depending on the model, the make the design, um. 60 to 80 bushings. 60 to a hundred bushings. What’s that number?

Edo Kuipers: Yeah. 92 for example. Or 74 or, yeah. In that area.

Joel Saxum: Right. So, so, and when you, and when your solution is engaged, when the, you have to bring the, bring the blade down tower and then fix it if you catch it early. Are you talking, we’re fixing six of these, we’re fixing 40 of these. What does it usually look like?

Edo Kuipers: It’s, uh, in the, in the area of 24 to 30.

Joel Saxum: Okay.

Edo Kuipers: The nice thing on that, the nice thing is on that if we working with a drilling machine, we can do that in 24 hours drilling. So limited time. Limited time of, of [00:08:00] taking out the bushings. And if we would wait longer and we need to repair 60 bushings, it takes, let’s say 60 hours to, to drill out, so to lower the cost of the repair.

Because it’s like a chain reaction. Once it starts, it, it grows to lower the amount of the repair and the cost of repair, let’s, let’s not wait too long.

Allen Hall: Okay. So that’s a really good input into this discussion because I think a lot of operators assume if I have to do this repair, replace the bushings, I’m replacing a number of bushings regardless of the level of damage, because they’re gonna fail eventually.

But you know, what you’re saying is that. It starts in a highly loaded couple of bushings and spreads from there, if you can, if you can fix or upgrade those particular bushings, then the remaining bushings may be okay.

Edo Kuipers: Correct. Because there is always a highly loaded, like you said, and there’s always a a side which is more tensile loaded, and the other side is more compressive loaded, and especially the tensile loaded part is, is [00:09:00]more severely for the fatigue.

Joel Saxum: The other side of this is a blade replacement. So you’re either gonna, you’re going to have to, you’re gonna do something like this, or you’re gonna replace the blade. And, but now again, we’re talking about this aging fleets remaining useful life, what spares look like out in the field. A lot of these turbines.

Spares are not readily available for them. Right. If we’re talking about, and we’re talking about different markets like you, you ju you guys just executed. We’re gonna talk about this a little bit, but you just executed this amazing project, uh, over in the APAC region. It’s not easy to get blades shipped over there, or like in Australia or South America, like in the States.

We’re kind of lucky people don’t realize this, but we’re kind of lucky that we have a fleet of 75,000 turbines because there are spares around for some things. However, as these blades get older, like nobody’s gonna do you a run of a 12-year-old, 15-year-old blade, it’s what, whatever’s on the ground around the world is what we have.

And that is it Ev And then in composites, again, everything can be repaired, but it’s just how much, what is the [00:10:00] economic case for? So you guys are building that economic case to make this make sense.

Edo Kuipers: A new blade, let’s, let’s. Have the old fashioned prices of 10 euros per kilo or whatever, and you have a blade of 15 tons that will cost you like 150,000 euros.

As a new blade, you already paid for that price. Then you have to do it a second time. It’s not only that, it’s also the waiting time. If you have to wait for one year, your loss, your loss in, in, in, in, in, in revenue. Also, let’s say like 100, 150, maybe 200,000 depending on your feed into reef tariffs that you get.

It’s also, that’s also a loss. So the total thing will cost you already like easily like 200, 300,000 euros for for one turbine, right? Or one for one rot blade. If you do a repair, then there’s a repair. It’ll cost you like a fraction of that. It’ll cost you maybe like 30, 40,000 euros.

Joel Saxum: Yeah. And the reality is, is when you [00:11:00] replace one blade, you normally are replacing all three.

I mean, unless you, unless you can find a, a matching, you know, a good, well you, you get lucky and you find one blade that has the weight certificate and a bending moment certificate that matches your other. Two that are up tower. Mm, pretty rare. More than likely you’re getting all three new blades. So then all of a sudden your 150 turns into 450 before you even start it.

Soren Kellenberger: Absolutely. And that’s, that’s if you can get a replacement blade because if you need to go back to a, a manufacturer Right, they, they will not sell you that blade for the original 150,000 Euros. Uh, so. If they at all have a mold before they get it started up and all the initial cost in, in getting that up and running, you are looking at 2, 3, 4 times the price of the, of the new blade.

So it, it really adds up if you have to replace. And there’s of course also the whole discussion right now with, um, the old blades and all the waste it’s, uh, creating. So from an environmental perspective, it’s [00:12:00] also a huge benefit to, uh, repairs instead have replaced. Uh, but, but the financial is, it’s just, uh, yeah.

Basically a no brainer, right?

Allen Hall: Oh yeah. The financials make total sense. And this is where we’re gonna get to the solution from WE four C, which is called Refit, which is a, a bushing upgrade and the workings together of two separate companies. So we have WE four C, which is, uh, based in the Netherlands of course, and then we.

We have Sorin and CNC onsite, which is based in Denmark, so they’re really relatively close to one another, and both companies are powerhouses in wind and, and fixing wind and making it more efficient and getting our turbines optimized for long-term duration, which. What we in the states have not been doing, but we’re, that’s gonna rapidly change in the next couple of months.

Uh, so this refit solution does make a lot of sense to me just because the demand is [00:13:00] gonna be there and we need to have some way of doing this. And, uh, this is what I want to talk to both of you about, because understanding how to replace these bushings, it, it seems at first, like it’s an impossible task.

You brought two powerhouses together to solve this problem. You wanna discuss how the two companies work together, we foresee and CNC onsite, and how this, uh, repair rework is accomplished.

Soren Kellenberger: I think if we, if we take it back a step, um, we at CNC or uh, onsite was originally involved in a plate repair project.

Uh. Before, actually before the, the Corona uh, uh, situation. Uh, so we had worked on a machine and made some, uh, tests in, in our workshop on this repair, drilling out bushings. Um, then Corona came and the project was stopped and never restarted again. So about four years, pretty much to the, [00:14:00] to the date because it was at the Huon wind, which is now coming up again in, in one and a half week.

Um, we were in, we met, uh, we foresee, uh, so we had this drilling technology sitting there, and I walked around and I saw these, uh, nice, uh, bushings and, and, uh, a couple of nice gentlemen standing there. So I approached, uh, IDO and, and Arnold and said, uh, Hey guys, this, uh, this, this looks nice. What is it? And, uh, we started talking about that.

Uh, they actually had the. Pushing technology ready. They needed someone who could drill out the old ones. And yeah, we had the technology to drill out the old ones and needed someone who could insert those replacement pushing. So it was actually, um, a very, a very good fit. And then the whole corporation just started off basically on trust.

I mean, we signed the NDA and stuff like that, but we just trusted each other and, and moved, uh, forward. And it took some time before getting to the first customer also. What you mentioned in the [00:15:00] beginning, right, Alan, that there’s, yeah, it looks nice, but has it been done before? It’s been, we’ve heard that question, uh, a lot of times.

Um, so it took some time before we got through all the testing and stuff like that, but, uh, now it’s up and running and, uh, works really well.

Edo Kuipers: At the third point, the customer said to us, if you can show a test with this number of cycles and fatigue, it was something like a certain level and a 1 million cycles test.

If you can show that to me, then we will sign the contract. So we sent two coupons, you one to a, to a Dutch Institute, independent, one to a German Institute who was doing um, um, coupon testings. And we said, okay, run it. Run them off both for 1 million cycles. And they had, they had the same result. So, and both, both have reached the 1 million cycles.

So we said to the customers, we did not provide one component with 1 million cycles, but two for you to, to make sure. And also at different test institute. [00:16:00] And then they signed the contract and at all went. Very fast after that.

Allen Hall: Well, yeah, if as soon as you can show the technology works in the laboratory, the next step is to get it deployed.

So the, the, the process works sort of like this. And, and stop me if I’m too far off because I’ve had to explain to me very slowly. Ada has done this very carefully. So let’s see if I can, uh, explain it to the teacher. I’m gonna take, I’m gonna remove the blade off. I’m gonna bring the blade down, and they’re gonna call Soren’s people at CNC onsite.

And they’re going to actually. Have tooling this amazing tooling to drill out this old bushing and make it such that this ados wonderful refit solution can slide into this new drilled spot that’s been perfectly honed. And this new bushing goes in and there’s a bunch of epoxies added behind it to hold that new bushing in place.

And then once that’s done, I move to the next one. And because the system is set up with CNC onsite to have [00:17:00] to go ahead and, and drill out multiple bushings, uh, very quickly, this process, once the blade is down, is actually very quick. So you’re talking about maybe a couple of days total to repair a blade that otherwise would be

Edo Kuipers: discarded.

This is, I’m very happy with this at the moment. And this is also with thanks to the um, uh, to the criteria, to the cap measurements of up tower we are doing. So this is the first step we have to do, of course. But thanks to that we only need a limited amount of bushing. So we are doing, let’s say like 24 to 30 bushings are being drilled out.

This takes us. 24 hours, more or less, we are doing it. We could do it in three shifts, so then it’s one day, but we are not doing it in one sh one shift. They, they are working neatly, they are working accurate and with the same team. And so they are doing three days. After these three days, they are, they are done with the drilling.

Um, then we need to start the [00:18:00] preparations, so the new bushings needs to be implemented. That will take us, let’s say like eight hours of preparations, because everything needs to be far tight and that that is essential for our solution. It needs to be low, far level, so all the air out. And then after this, that takes about eight hours, and after that we have the infusion day.

That’s a really exciting day always, because once. The resin is running. We can’t stop it anymore. Right? So this, this day is also, let’s say eight hours. So, and then we have some finishing because it would be nice if we are hoisting up the blade again. A tower that the, that the root is, is flat. Yeah. All the resin pieces are off.

And we may have to make sure that, uh, that all the, all the bushings are aligned well for the proper load distributions. Um, another, let’s say another few hours, maybe eight hours. So then we are 48 hours, 50 hours of the whole process working with three or four people. That’s it.

Allen Hall: [00:19:00] Wow. And does it take anybody special to be on site from like the CNC onsite?

You know, c NNC onsite makes these great machines that are highly accurate. Uh, Soren, do you need to have specialized people on site or are you training people that are local to do this work?

Soren Kellenberger: We are training local people. So that is, that is part of, of the whole solution that, that we do a technology transfer.

So it’s, people are trained with this specific project. We started by having the, the team in Europe, uh, so they had some, some training days with, uh, IDO and the guys in the Netherlands on the, uh, whole mounting and infusion technology. And then they came to our workshop and trained in operating the drilling machine.

Afterwards. Then for the startup, we send the technicians, uh, to, to the customer, um, who supported for a couple of weeks, and then we went back. Uh, and then we are basically, uh, always ready to support. But on teams or whatever, we can set up a link and, and [00:20:00] a system if needed. They are running with it, uh, very well.

So it’s, it’s been very limited what we’ve had to do. Uh, we get some feedback on the drilling process so we can optimize some parameters and, and step by step, uh, improve the process time. We’ve done some optimizations to the drills, uh, to make them last longer and, and do. Those, uh, things more efficiently, but they are basically running on their own

Joel Saxum: guys.

I think that’s something to make sure that we don’t breeze over here as well. Is the local content part of your solution. So you’ve done all the expert engineering, uh, figuring out the processes, of course, all the, the precision machining equipment from Soren’s team as well, but you can export it to different locales and train up the local staff and get them moving.

So places like it’s, it’s expensive. It’s difficult to get people into South Asia. It’s expensive, it’s difficult to get people into South America, to Australia, to, to anywhere really. You’re gonna export this. However, what you’re also doing is bringing local jobs, local [00:21:00] work, local revenue to the local teams.

And I know that that makes a lot of, a lot of people happy. Um, including, I know, like we’re, we’re sitting in the States, right? There’s a lot of ISPs over here, hopefully listening to this. They’re saying like, Ooh, we’d like to be the people that implement this solution over in the States. Let’s get ahold of these guys.

Uh, so kudos to you on that as well.

Edo Kuipers: Yes. The idea is indeed to have, um, on different regions in the world, uh, different, uh, repair hubs so that we can always work with the same teams, with the, with the, with the same people. So we train them, educate them, and then of course, from the Netherlands and of course from Denmark, we still, we will always support them, but it can also be done by a teams or a conference calling.

Allen Hall: And let’s talk about the Southeast Asia. Project you just completed successfully and uh, it looked fantastic. That was the first major project that you’ve tried this technology on. Besides everything in a laboratory, kind of one off things, but now you’re going to scale. This is a big step. [00:22:00] How did it go?

How did that process start? What did it look like afterwards?

Edo Kuipers: Um, how did it start? Uh, by doing it, I mean, sir and his team went on site, of course, and we encountered difficulties, of course, first time with drilling. And, um, that had multiple reasons. So the guys, uh, even the, the, the, the colleague of Sir went, went back to Denmark.

He changed, he fixed something on a drill, had sent a new type of drill and it ran perfectly. So from there, from that point, the drilling was no problem anymore. Then after we created the holes together, um, of course we have to do the infusion. And going from going from infusing like five bushings in a row, we had to go to 30 in a row.

And that was in the beginning, quite challenging. Um, to have, so it was a little bit like keep your fingers crossed if everything is going fine, but it works somehow. Um, it works [00:23:00] and, and all the resin came out. So we are quite happy with that. Uh, of course there are some fine tuning in the processing in the quality.

Uh, but that’s, that’s important for us is, is, is to keep, you need to keep following the. The quality processes. If you, if you strictly follow the quality processes, make sure it’s vacuum tight, make sure that you work in sections, so don’t open your resin folds all at the same time, one by one correctly.

And then just monitor and make sure that, of course, refresh your resin from time to time. Because that’s a pot life thing, and it takes, let’s say like maybe two hours before the whole resident is going through the bushing and also in the depth direction that is being impregnated well. Um, so you have to make sure that your pot life is under control.

And also we work with a tent, which is like 100 square meters, which is air conditioned, and, and that all contributes to a, [00:24:00] a controlled process. And yeah, that was very scary for the first time. I must admit that if you do second time. You get more relaxed. And the third time, it’s like driving a car the first time.

Oh, this, I need to pay attention to the gear. In the, in, in Europe, we have gears and, um, on the car and um, we, we need to, we need to drive and look around us and the navigation system. Um, so, and at a certain point it’s all going automatically. Right. How many blade did you repair in Southeast Asia? 18. Now we are working the, the, the sixth set.

Set number six has just completed, and I know this every week, I have contact, uh, with, with, with, with. With. With one guy there. It’s, it’s, we know each other good. So he, he gives us the feedback and it costs me every week. It costs me half an hour, not more.

Joel Saxum: It’s usually not one blade. It’s usually the whole step has an issue, correct?

Edo Kuipers: Yes and no. Um, what they do now at the moment, um, they, they, [00:25:00] they, they, they see that one, one blade has, um, uh, a problem. So they, they, they already. Start thinking ahead by taking all three blades down. So even if, if one or two blades within the set does not have the variable capping, they know in half a year it will happen.

That’s the experience they already have. And the the, there is the certain. They have a certain agreement here with the crane. The crane is coming, let’s say they use a crane every month for a fixed period. So they say, let’s hoist the complete set down. Then we have three weeks to repair, and in the fourth week we will hoist it out again.

Joel Saxum: Yeah. And the, and the technicians on site, once they’re trained up, uh, they’re loving it because whether it’s in the hot in South, south Asia, or if you’re doing this in the cold, you’re working in a tank. So if they got an extra couple blades to work on as a blade technician. I’m all for it. I’m all for it.

A little bit more time in the AC or in the heat and nice kind, controlled facility. It’s,

Soren Kellenberger: uh, I think the, the guys will like that a lot in the [00:26:00] field. One of the benefits you, you get also is, as Ido mentioned in, in the beginning, if you catch it early, you have fewer, uh. Bushings to repair. So, uh, you, if you catch it or, or repair it while you have your blades down already, you can repair fewer bushings.

And in terms of process time, it’s also a little bit faster. That’s also what we learned to, uh, to drill out the bushings when they are not. Too loose. Um, the more loose they get, the more risk you have of vibrations when you start drilling and that can potentially damage your drills. Uh, um, and it, it just adds to the process time.

So. There are a lot of benefits by catching these, uh, things early and getting the process, uh, completed at an earlier damage stage.

Allen Hall: Now you’ve completed your first big project. What’s next? It sounds like there’s a lot of opportunity worldwide to do this refit process.

Edo Kuipers: Yeah, we, the, the, the first, the first [00:27:00] team is the, is our number one team.

You can see it also here on the, on the breast. And, um, we are now looking basically a number two team, which is, is as excellent as the number one team. Um, so yeah, it’s not only that, um, we have to do, I mean. If you would like to have this, this technology implemented, um, it’s, it’s going Pfizer versa. So, um, very, very important is that we are working together with teams, service teams, which 100% trust each other.

That’s where it starts already. Um, and they are fixed. So if, if you have fixed teams, you teach them and they, they, they, they, they, they learn by experience and that that’s how it should be. Um, so yeah. The next step is, is we are talking with. Next step is we are talking with different, uh, potential, um, service companies, um, worldwide.

So we are talking within America with, with one or two, um, potential, um, good guys, good [00:28:00] groups. Um, the same in, in India, for example, and the same in, in, in South America. That’s, that’s our aim to have, let’s say in, in South America. Two service companies, uh, in, in, in India, two or three, uh, um, in India, in America, one, two, or three or whatever.

So that’s, we are now discussing with these parties, and it’s not only one direction, okay? We want to sell it to you. Now, it’s also the other direction. Are you capable? How do we want to work with 24 hour cycle? Do you have a place where we can install everything? So that’s our next step to explore.

Allen Hall: Yeah.

And Sorin, you have to start making more machines. I hope so.

Soren Kellenberger: No, it’s, it’s definitely, we’ve, we’ve seen a lot of interest and, and we’ve also had numerous contacts over the years. But again, it’s been back to this, have this been done before and. It sort of, no one wanted maybe to be the first, but now the first commercial project is, is out there.

It’s, it’s still [00:29:00] ongoing. And, and once this is completed, we will have installed more than a thousand bushings. Uh, so, so I think it’s, it’s a decent. Proof of concept. It’s a, it’s a real case. It’s not just one blade or one set. It’s, it’s actually a, a, a larger farm that, where, that we have, will have repaired once, uh, this project is, is, uh, 100% completed.

So it’s, it’s going really well. Uh, and I think that of course they will, once the potential customers see that, that this project is now open and running, it will move forward with, uh, contracts for, for other projects. But who is gonna be the first is still, uh, difficult to say, but, uh, I’m pretty sure that, that there will be more.

Edo Kuipers: Yeah. We would also quite be keen on getting on the table with the big OEMs because there are many parks which have still some kind of, uh, service contract, eh, uh, full service agreement or whatever. So even if park owners, many time [00:30:00] park owners say to us, Hey, we would like to have your technology implemented because that sounds to be the most robust one.

Um, but you need to convince the, the, the, the, the Big O oms. Um, and sometimes that is, that is, that is a difficult part because you need to go through, through these different steps with a lot of decision makers, uh, in these organizations. And that takes time. So request is, are on these big, OMS is to define clear criteria for us.

How, what should be, what should we fulfill? And if we fulfill this. Basically, do we then have a deal with each other? Because in the end, for us, we need to help those park owners because they are in the end, eh, um, they have the, they are feeling the pain on, on, on, on this kind of, um, yeah, sometimes hidden problems.

Allen Hall: Well, if you’re an OEM or an operator, where do you start this process? Who do you call first? Do you call we foresee or do you call CNC onsite or does it matter?

Soren Kellenberger: Call either of us and, uh, we [00:31:00] will be, make sure to, uh, involve the other parts. So that’s where the trust and cooperation comes into play. Uh, yeah, just reach out and, uh, we will, we will.

Set up joint meetings.

Allen Hall: The website for CNC onsite is CNC onsite.dk because they’re in Denmark. And the website for WE four C is we the number four, letter C, letter e.eu. And either one of those addresses will get you to the information you need about the refit and. Uh, get you started because as we’ve seen the United States, a lot of things are changing and worldwide.

We need to keep these turbines up and running longer. The way to do that is to put a little bit of money into them now instead of spending a whole bunch of money later. This is why we love we four C and C and C onsite because they’re saving operators, literally millions of dollars. So. You know, and Soren, thank you so much for being on the podcast.

We, we love having you. And as you finish up the Southeast Asia project, you gotta come back on after you [00:32:00] finish those thousand bushings and give us an update. Absolutely. We’ll be happy to.

Edo Kuipers: Yes, thanks a lot. We are fully happy to.

Allen Hall 2025: Welcome to the Uptime Wind Energy Podcast. I’m your host, Allen Hall. I’m here with Yolanda Padron in Austin, Texas, who is back from the massive wedding event. Everybody’s super happy about that, and Rosemary Barnes had her own adventures. She just got back from China and Rosemary. You visited a a lot of different places inside of China.

Saw some cool factories. What all happened?

Rosemary Barnes: Yeah, it was really cool. I went over for an influencer event. So if you are maybe, you know, in the middle of your career, not, not particularly attractive or anything you might have thought influencer was ruled out for you as a career. No one, no one needs engineering influencers in their [00:01:00] forties.

It’s incorrect. It turns out that’s, that’s where, that’s where I, I found myself. It was pretty cool. I, I did get the red carpet rolled out for me. Many gifts. I had to buy a second bag to bring home the gifts, and when I say I had to buy a second bag, I had to mention. Oh, I have so many gifts, I’m gonna need another bag.

And then there was a new bag presented to me about half an hour later. But, so yeah, what did I do? I got to, um, as I was over there for a Sun Grow event. Huge, huge event. They, um, it’s for, it’s for their staff a lot, but it’s also, they also bring over partners. They also bring over international experts to talk about topics that are relevant to them.

Yeah. They gave everybody factory tours in, um, yeah, in, in shifts. Um, I got to see a module assembly factory, so where they take cells, which are like, I don’t know, the size of a small cereal box, um, and assemble them into a whole module. Then the warehouse, warehouse was [00:02:00] gigantic. It, um, was, yeah, 1.8 gigawatt hours worth of cells that couldn’t hold in that one building.

They’re totally obsessed with fire safety there in everything related to batterie, like in the design of the product, but also in, in the warehouse. And they do, yeah, fire drills all the, all the time. Some of them quite big and impressive. Um, I saw inverter manufacturing facility that was really cool.

Heaps of robots. Sw incredibly fast. Saw a test facility.

Allen Hall 2025: So was most of the manufacturing, robotics, or humans?

Rosemary Barnes: Yeah. So at the factory it was like anything that needed to be done really fast or with really good quality was done by robots. So they had, um, you know, pick and place machines putting in. Um, you know, components in the circuit board, like just insane, insane rate.

I’m sure it’s quite, quite normal, but, um, just very fast. Everything lined up in a row. Most of their quality control is done by robots. Um, so it does well it’s done by ai, I should say. [00:03:00] Taking photos of, of things and then, um, AI’s interpreting that. Repairs, I think were done by humans. There were humans doing, um, like custom components as well.

Like not every product is exactly the same. So the custom stuff was done by humans.

Allen H: So that’s the Sun Grove facility, right? You, but you went to a couple of different places within China?

Rosemary Barnes: Yeah, I went to another, a factory, a solar panel, a factory, um, from Longie. That was really cool too. I got to see a bit more probably of the, um, interesting, interesting stuff there, like, uh, a bit more.

Um, yeah, I don’t, I dunno, processes that aren’t, aren’t so obvious. Not just assembly, but um, you know, like printing on, um, bus bars and, you know, all of the different connections and yeah, it was a bit, a bit more to it in what I saw. Um, so that was, but it, it’s the same, you know, as humans are only involved when it’s a little bit out of the.

Norm or, um, where they’re doing repairs, actual actually re [00:04:00]repairing. You know, the robots or the AI is identifying which components don’t meet the standard and then they’ll go somewhere where a human will come and, um, fix them.

Allen H: Being the engineer there. Did you notice where the robots are made? Was everything made in China that was inside the factory or were they bringing in outside?

Technology.

Rosemary Barnes: I didn’t think to look for that, but I would assume that it was Chinese made, also

Allen H: all built in country

Rosemary Barnes: 20 years ago that wouldn’t have been the case, but I think that China has had a long, a long time to, to learn that. Again, it’s not like, it’s not, it’s not rocket science. These are, these are pick and place machines, you know, like I remember working on a project very early in my career, so.

Literally 20 years ago, um, I was working with pick and place machines. It’s the same, it’s the same thing. Um, some of them are bigger ’cause they’re, you know, hauling whole, um, battery packs around. It’s just the, um, the way that it’s set up, but then also the scale that they can achieve. You just, you can’t make things that cheap if you don’t have the [00:05:00] scale to utilize everything.

A hundred percent. Like I said, wind turbine towers is a really good example. ’cause anyone, any steel fabricating

Allen H: shop

Rosemary Barnes: could make a wind turbine tower. Right? They, they could, they could do that. You know, the Chinese, um, wind turbine tower factories have the exact right machine. They don’t have a welder that they also use for welding bits of bridges or whatever.

Uh, they have the one that does the exact kind of world that they need, um, for the tower. They, you know, they do that precisely. Robotically, uh, exactly the same. And, you know, a, a tower section comes on, they weld it, it moves off to the next thing, and then a new one comes on. They’re not trying to move things around to then do another weld in the same machine.

You know, like they’re, um, but the exact right. Super expensive machine for the job costs a whole bunch to set up a factory. And then you need to be making multiple towers every single day out of that factory to be able to recoup on your cost. And so that is [00:06:00] the. The, um, bar that is just incredibly hard slash impossible for, um, other countries to clear.

Allen H: Can I ask you about that? Because I was watching a YouTube video about Tesla early on Tesla, where they wanted to bring in a lot of robotics to make vehicles and that they felt like that was the wrong thing to do. In fact, they, they, they kinda locked robots in and realized that this is not the right way to do it.

We need to change the whole process. It was a big deal to kind of pull those. Specialized piece of equipment, robots out and to put something else in its place in that they learned, you know, the first time, instead of deciding on a process, putting it in place and then trying to turn it on, see if it works, was to sort of gradually do it.

But don’t bolt anything down. Don’t lock it in place such that it doesn’t feel like it’s permanent. So you engineer can think about removing it if it’s not working. But it sounds like this is sort of the opposite approach of. A highly specialized [00:07:00] machine set in place permanently to produce. Infinite amounts of this particular product, does that then restrict future changes and what they can make or, I, I, how do they see that?

Did, did you talk about that? Because I think that’s one of an interesting approaches.

Rosemary Barnes: I didn’t actually get as much chances I would’ve liked to speak to engineers. Um, I was talking mostly to salespeople and installers. Um, so they know a lot, but I couldn’t, um, like in the factory tours, I was asking questions.

Um. That kind of question and, and they could answer all, all that. Um, but outside of that, and I couldn’t record in the factory obviously. Um, but I did, I did take notes, but what I would say is that they would have a separate facility where they would be working out the details of new products and new manufacturing processes and testing them out thoroughly before they went and, you know, um, installed everything correctly.

But what I do hear is that, you know, especially with solar power. Maybe to [00:08:00] batteries to a lesser extent. You, you know, you like, you have these kind of waves of technology. Um, so you know, like everyone’s making whatever certain type of solar cell and then five years later, um, there’s a new more efficient configuration and everybody’s making that.

And I know that there are a lot of factories that kind of get scrapped. Um, and the way that China’s set up their, like, you know, their economy around all this sort of thing is set up is that it’s not that, like every company doesn’t succeed. Right. They SGO was a big exception because they’ve been going since 1997, I think it was.

It was started by a professor quid his job and hired a room across the, across the road from his old university and, you know, built his first inverter and, um, you know, ’cause he, he could see that. Uh, the grid was gonna have to change to incorporate all of the solar power that was coming, which to be honest, in 1997, that was like pretty, pretty farsighted.

That was not obvious to me when I started working in solar in mid two thousands. And it was not obvious to me that this was a winner.

Allen H: Well, has sun grow evolved then quite a bit? ’cause if you’re [00:09:00] saying that they’ve minimized the cost to produce any of their products by the use of robotics, they have been through an evolutionary process.

You didn’t see any of the previous generations of. Factories. You, you were just seeing the most modern factory that that’s actually producing parts today. So is that a, is that a, is that just a cost mindset that’s going on in China? Like, we’re just gonna produce the lowest cost thing as fast as we can, or is it a market penetration approach?

What are, what were, were the engineers in management saying about that?

Rosemary Barnes: I think there’s a few different aspects to that, like within China. So Sun Grow is the big company with a long track record and they’re not making the cheapest product out of China. So I think that they are still trying to make the cheapest product, but they’re not thinking about it just in the purchase price.

Right. They’re thinking more in terms of the long, long term. You know, they’ve been around for 30 years and probably expect to be around for another 30 years. They don’t wanna be having [00:10:00] recalls of their products and you know, like having to, um. Installers in particular are probably working with them because they know that they won’t have to go back and do rework and the support is good and all that sort of thing.

So they’re spending so much money on testing and you know, just getting everything exactly right. But I don’t think that that’s the only way that China is doing it. There’s, you know, dozens, probably hundreds of companies. Um. Doing similar stuff between Yeah, like solar panels and associated stuff like inverters and, and batteries.

So many companies and all of them won’t succeed. You know, sun Girls Facility in, I was in her and it’s huge, you know, it’s like a, a medium sized country town. Just their, um, their campus there, they’re not, they’re not scrapping that and moving to a new site, you know, they’re gonna be. Rejiggering and I would expect that, you know, like everything’s set up exactly the way it needs to be, but it’s not like gigantic machines.[00:11:00]

It’s not like setting up a wind turbine blade factory where it’s hard if you designed it for 40 meter blades, you can’t suddenly start making 120 meter blades. Like it’s, they will be able to be sliding machines in and out as they need to. Um, so I, I, yeah, I guess that it’s some, some flexibility. But not at the cost of making the product correctly.

Allen H: Did you see wind turbines while you were in China?

Rosemary Barnes: I, the only winter I saw, I actually, I saw, because I caught the train from Shanghai, I actually caught the fast train from Shanghai to, which is about, it depends which one you get between like an hour 40 or three hours if it stops everywhere. Um, and I did see a couple of wind turbines on the way there, out the window, just randomly like a wind turbine in the middle of a, a town.

Um, so that was a bit, a bit interesting. But then in the plane, on the way back, the plane from Shanghai to Hong Kong, I, at the window I saw a cooling tower of some sort. So either like a, yeah, some kind of thermal [00:12:00] power plant. And then. Around all around, well, wind turbines, so onshore wind turbines. So I don’t know.

Um, yeah, I, I don’t know the story behind that, but it’s also not a particularly windy area, right? Like most of the wind in China is, um, to the west where, uh, I wasn’t

Allen H: as wind energy professionals, staying informed is crucial, and let’s face it. 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 content you need. Don’t miss out. Visit PS win.com today. So there are two stories out of the US at the minute that really paint a picture of the industry. It was just being pulled in opposite directions. The Department of Interior announced agreements to terminate two more.

Offshore wind leases, uh, [00:13:00] Bluepoint wind and Golden State wind have agreed to walk away from their projects. Global Infrastructure Partners, which is part of BlackRock, will invest up to $765 million in a liquified natural gas facility instead of developing blue point wind. Ah. And Golden State Wind will recover approximately $120 million in lease fees after redirecting investment to oil and gas projects along the Gulf Coast, and both companies say they will not pursue further offshore wind development in the United States.

Well, we’ll see how that plays out. Right? Meanwhile. In Massachusetts Vineyard Wind, which has been fighting with GE Renova recently has activated its long awaited power purchase agreement with three utilities. The contract set a fixed electricity price of drum roll please. [00:14:00] $69 and 50 cents per megawatt hour for the first year and a two and a half percent annual increase.

Uh, state officials say the agreements will save rate payers $1.4 billion over 20 years. So $69 and 50 cents per megawatt hour is a really low PPA price for offshore wind. A lot of the New York projects that. Renegotiated we’re somewhere in the realm of 120 to $130 a megawatt hour, and there’s been a lot of discussion in Congress about the, the usefulness of offshore wind.

It’s intermittent blahdi, blahdi, blah. Uh, but the, the big driver is what costs too much. In fact, it doesn’t cost too much. And because it’s consistent, particularly in the wintertime, uh, electricity prices in Massachusetts in the surrounding area are really high. ’cause of the demand and ’cause how cold it is that this offshore wind project, vineyard wind would be a huge rate saving.

And [00:15:00] actually the math works out the math. Math everybody. Do you think this is, when we go back five years from now, look back at this. This vineyard wind project really makes sense for Massachusetts.

Yolanda Padron: I think it really makes sense for Massachusetts. I’m really interested to know what the asset managers are thinking on the vineyard wind side, um, and if they’re scared at all to take this on.

I mean, it’s great and I’m sure they can absolutely deliver. Like generation I don’t think should be an issue. Um. I just don’t know. It’s, it sounds like they’re leaving a lot of money on the table.

Allen H: I would say so, yeah. But remember, the vineyard win was one of the early, uh, agreements made when things were, this is pre Ukraine war, pre Iran conflict on a lot of other, a lot of other things.

It was pre, so I remember at the time when this was going on that. P. PA prices were higher than obviously a lot of other [00:16:00] things. Onshore solar, onshore wind, it would, offshore is always more expensive, but I don’t remember $69 popping up anywhere in any filing that I remember seeing. So even if they had said $69 five years ago, I think that would’ve still been like, wow, that’s pretty good for an offshore wind project.

And now it looks fantastic for the state of Massachusetts

Yolanda Padron: because I know that there’s sometimes, and we’ve talked about this in the past, right? There are sometimes projects where, you know, you think you, you’ve got a really good price and you’re really excited about it, and then it goes into operation and then like a couple years down the road, prices increase quite a bit and it’s not the worst thing in the world.

But you do just kind of think a little bit like, I wish I could. Renegotiate this or you know, just to get, to get our team a bit of a better deal or to get a bit more money in operations and everything.

Allen H: Does this play into Vineyard wind claiming $850 [00:17:00] million in dispute with GE Renova that at $69 PPA, there’s not a lot of profit at the end of this and need to get the money out of GE Renova right now, and maybe why GE Renova wants to get out of this because they realize.

The conflict that is coming that they need to separate the, the themselves from this project. It’s, it’s very, as an asset manager, Yoland, as you have done this in the past, would you be concerned about the viability of the project going forward, or is all the upfront costs. Pretty much done in that operationally year to year.

It’s, it’s not that big of a deal.

Yolanda Padron: As an asset manager taking this on, I’d probably have started preparation on this project a lot earlier than other of my projects like I do. I know that usually there’s, you know, we’ve talked about the different teams, right, throughout the stages of the project until it goes into operations, [00:18:00] but.

And usually you don’t have a lot of time to prepare to, to make sure all of your i’s are dotted and t’s are crossed, um, by the time you take the project and operations from a commercial standpoint. But this project, I think would absolutely, like you, you would need to make sure that a lot of the, of the things that you’re, that might be issues for some of your projects like aren’t issues for this project.

Just to make sure at least the first few years you can. You can avoid a lot of, a lot of turmoil that the pricing and the disputes and the technical issues are gonna cause you, because I feel like it’s just, there’s, there’s just so many things that just keep this side, just keeps on getting hit, you know?

Allen H: Well, I, I guess the question is from my side, Yolanda, is obviously inflation, when this project started was pretty consistent, like one point half, 2%. It was very flat for a long time. And interest rates, if you remember when this project started, were very, very low. Almost [00:19:00] nonexistent, some interest rates.

Now that’s hugely different. How does a contract get set up where a vineyard can’t raise prices? It would just seem to me like you would have to tie some of the price increase to whatever the inflation rate is for the country, maybe even locally, so that if there were a, a war in Ukraine or some conflict in the Middle East.

That you, you would at least be able to, to generate some revenue out of this project because at some point it becomes untenable, right? You just can’t afford to operate it anymore. And,

Yolanda Padron: and I think, um, I, I haven’t, I obviously haven’t read the, the contracts themselves, but I know that there’s sometimes there, it’s pretty common for a PPA to have some sort of step up year by year.

And it’s usually, it can be tied to, um, the CPI for. Like the, the change in CPI for the year to year. So you’re [00:20:00] absolutely like, right, like maybe, I mean, hopefully they’re, they’re not just tied to the fixed 69 bucks per megawatt hour. Um, but, but yeah, to, to your point like that, that price increase could, could really save them.

Now that we’re, we’re talking the, the increase in, in inflation right now and foreseeable future,

Allen H: if you think about what electricity rates are up in the northeast. I think I was paying 30 cents a kilowatt hour, which is 300. Does that sound right? $300 a megawatt hour. Delivered at the house, something like that.

Right? So

Yolanda Padron: prices in the northeast are crazy to me,

Allen H: right? They’re like double what they are in North Carolina. Yeah.

Delamination and bottom 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 [00:21:00]before they become expensive burdens. Their non-destructive test technology penetrates deep dip blade materials to find voids and cracks.

Traditional inspections completely. Miss C-I-C-N-D-T Maps Every critical defect, delivers actionable reports and provides support to get your blades. Back in service, so visit cic ndt.com because catching blade problems early will save

Yolanda Padron: you millions.

Allen H: Well, sometimes building a wind farm turns out more than expected construction workers at a 19 turbine wind project in lower Saxony Germany under Earth. What experts call the largest Bronze age Amber Horde ever found? The region, the very first scoop of an excavator brought up bronze and amber artifacts that stopped construction and brought archeologists back to the site.

Uh, the hoard has been dated between [00:22:00] 1500 and 1300 DCE and is believed to have belonged to at least three. Status women possibly buried as a religious offering. Now as we push further and further across Germany with wind turbines and solar panels for, for that matter, uh, we’re coming across older sites, uh, older pieces of ground that haven’t been touched in a long time and we’re, we’re gonna find more and more, uh, historically significant things buried in the soil.

What is the obligation? Of the constructor of this project and maybe across Europe. I, I would assume in the United States too, if we came across something that old and America’s just not that old to, to have anything of, of that kind of, um, maybe value or historically significant. What is the process here?

Rosemary Barnes: I assume that they’ve gotta stop, stop work. Um, yeah, that’s my, my understanding and I don’t think, do you have [00:23:00] grand designs in America?

Allen H: I don’t know what that is. Yes.

Rosemary Barnes: So missing out by not having that chat. It’s a TV show about people who are building houses or doing, um, ambitious renovations, and it just, it follows, it follows them.

You can learn a lot about project management or. The consequences if you decide that you don’t need to, project management isn’t a thing that you need to do. Um, anyway. I’m sure that in some of those ones I’ve seen they have had work stop because in their excavation they found a, um, yeah, some, some kind of relic, um, from the, from the past.

So based on that very well-credentialed experience that I have, I can confidently say that they would be stopping stopping work on that site. I mean, it’s so bad, bad for the developer, I guess, but it’s cool, right? That they’re, you know, uncovering, uh, new archeology and we can learn more about, you know, people that lived thousands of years ago.

Allen H: It, it does seem [00:24:00] like, obviously. Do push into places where humans have lived for thousands of years. We’re going to stumble across these things. Does that mean from a project standpoint, there’s, there’s some sort of financial consequence, like does the lower Saxony government contribute to the wind turbine fund to to pay the workers for a while?

’cause it seems like if they’re gonna do an archeological dig. That that’s gonna take months at a minimum, may, maybe not, but it usually, having watched these things go on it, it’s. It’s long.

Rosemary Barnes: But wouldn’t that be something that you’d have insurance for?

Allen H: Oh, maybe that’s it.

Rosemary Barnes: You know, it seems to me like an insurable, an insurable thing, like not so hard to, it would’ve affected plenty of other, like any project that involves excavation in Europe would come with a risk of, um, finding Yeah.

An archeological find. And having work stopped, I would assume.

Allen H: Yolanda, how does that work in the United States do, is there some insurance policy towards finding [00:25:00] a. Ancient burial ground and what happens to your project?

Yolanda Padron: I don’t know. I, um, the most I’ve heard has been, it’s just talking to like the government and like the local government and making sure that you have all your permits in place and making sure, you know, you might need to, to have certain studies so you know, you might not have to get rid of the whole wind farm or remove the hole wind farm, but at least a section.

Of it has to be displaced from what you originally had thought. I don’t know. I know it happens a lot in Mexico where you get a lot of changes to construction plans because you find historical artifacts or obviously not everybody does this, but like. Tales of construction workers who will like, find, they’re so jaded from finding historical artifacts that they just kind of like take and then dump them to the next plot over to not deal with it right now.

Not that it’s anything ethical, uh, or done by everybody, [00:26:00] uh, but it’s, but, but it’s a common occurrence, a relatively common occurrence.

Allen H: You would think it where a lot of wind turbines are in the United States, which is mostly Texas and kind of that. Midwest, uh, wind corridor that they would’ve stumbled across something somewhere.

But I did just a quick search. I really hadn’t found anything that there wasn’t like a Native American burial ground or something of that sort, which they previously knew. For the most part. It’s, so, it’s rare that, that you find something significant besides, well, maybe used some woolly mammoths tusks or something of that sort.

Uh, in the Midwest, it’s, it’s, so, it’s an odd thing, but is there a. A finder’s fee? Like do does the wind company get to take some of the proceeds of, of this? Trove of jewelry.

Rosemary Barnes: I, I would be highly surprised.

Allen H: Well, how does that work then? Rosemary?

Rosemary Barnes: I’d be highly surprised if that’s the case in Europe. I bet it would happen like that in America.

Allen H: Sounds like pirate bounty in a sense.

Rosemary Barnes: In, in Australia it wouldn’t be like that because [00:27:00]you, when you own land, you don’t actually. You, you own the right to do things from surface level and above, basically. I don’t know how excavation works. So you don’t generally have a a right to anything you find like that?

I mean, you shouldn’t either. It’s not, it’s not yours. It’s a, it belongs to the, I don’t know, the people that, that were buried. When you then to the, the land, like, I guess. The government in some way. I mean, in Australia it’s, um, like we don’t have so many archeological fines that you would find from digging.

I mean, it’s not that there’s none, but there’s not so many like that. But it is pretty common that, you know, there are special trees, um, you know, some old trees that predate, uh, white people arriving in Australia. And, um, you know, that have been used for, you know, like it might have a, a shield that’s been, um.

Carved out of it. Or, uh, hunting. Hunting things, ceremonial things, baskets, canoes, canoe like things, stuff like that. They call ’em a scar [00:28:00] tree ’cause they would cut it out of a living, living tree. And you know, so when you see a tree with those scars and that’s got, um, cultural significance. There’s also, you know, just trees that were, um.

That that was significant for cultural reasons and so you wouldn’t be able to cut down those trees if you were building any, doing any kind of development in Australia and a wind farm would be no different. I know that they are, there are guidelines for, if you do come across any kind of thing like that or you find any anything of cultural significance, then you have to report it and hopefully you don’t just move it onto the neighboring property.

Allen H: I know one of the things about watching, um. Some crazy Canadian shows is that. Uh, you have to have a Treasure Hunter’s license in Canada. So if you’re involved in that process, like you can’t dig, you can’t shovel things, only certain people can shovel. ’cause if they were to find something of value, you.

You’ll get taxed on it. So there’s just a lot of rules [00:29:00] about it. Even in Canada,

Rosemary Barnes: if I was an indigenous Australian and you know, some Europe person of European descent came and found some artifacts, uh, aboriginal. Artifacts. I would be pissed if they just took it and sold it. Like that’s just clearly inappropriate right.

To, to do that. So you, I don’t think it should be a free for all. If you find artifacts of cultural significance and you just, it’s, you find its keepers that, that doesn’t sound right to me at all.

Allen H: Can we talk about King Charles II’s visit to the United States for a brief moment?

Uh, he is a really good ambassador, just like, uh, the queen was forever. He’s, he does take it very seriously and the way that he interacted with the US delegation was remarkable at times in, in terms of knowing how to deal with somebody that there’s a war going on right now. So there’s a lot [00:30:00] happening in the United States that, uh, not only could it be.

Uh, respecting both sides of the UK and the United States’ position in a, in a number of different areas, but at the same time being humorous, trying to build bridges. Uh, king Charles, uh, had the scotch whiskey tariffs removed just by negotiating with President Trump, and sometimes that’s what it takes.

It’s a little bit of, uh. Being a good ambassador.

Allen H: Yeah. The very polished you would expect that. Right? But this is the first visit of. The king to the United States, I believe. ’cause he, he’s been obviously as a prince many, many, many times to the United States. [00:31:00]But this time as, as a, the representative of the country, the former representative or head of the country, which was unique.

I think he did a really good job. And I wish he, they would’ve talked about offshore wind. Maybe he could’ve calmed down the administration on offshore wind.

Rosemary Barnes: I bet that’s one of the, the goals. I mean, that’s an industry that’s important to. So

Allen H: I wonder if that happened actually. ’cause that’s not gonna be reported in, in the news, but how the UK is going on its own way in terms of electrification and I guarantee offshore wind had to come up it.

Although I have been not seen any article about it, I, I find it hard to believe that King Charles being the environmentalist that he is, and a proponent of offshore wind for a long time. Didn’t bring it up and try to mend some fences.

Rosemary Barnes: Maybe he’s playing the long game though. I mean, Trump is pretty, he’s transactional, but he also, you know, he has people that he really likes and you know, will act in their interests.

So maybe it’s enough to just be [00:32:00] really liked by Trump, and then that’s the smartest way you can go about it.

Allen H: Did you see the gift that King Charles presented to, uh, the US this past week?

It was a be from, uh, world War II submarine, which was the British, I dunno what the British called their submarines, but it was, the name of it was Trump. So they had the bell from. The submarine when it had been commissioned and they, they gave that to the United States, or give to the president. It goes to the United States.

The president doesn’t get to keep those things, but it was such a smart, it’s a great president. It’s such a smart gift, and somebody had to think about it and the king had to deliver it in a way that got rid of all the noise between the United States and the uk. Brought it back to, Hey, we have a lot in common [00:33:00] here.

We shouldn’t be bickering as much as we are. And I thought that was a really smart, tactful, sensible way to try to men some fences. That was really good.

I’ve enjoyed quite a few works from the poet whose work appears at left, but this one speaks to me most clearly.

Money means everything, and the value we put on the lives of our children pale in comparison.

Bizarre Moments in Western Philosophy

Published

Schopenhauer’s pessimism is essentially everything he left us, and his quote here is representative of that.

We can’t change our birthplace, but does anyone want to do that anyway?  We can change anything else about us that we choose, and we certainly don’t spend the rest of our lives defending anything.
