Allen Hall: We have really interesting patents this week, Phil, including this first one from Siemens Gamesa, and it is a wind turbine blade with an advanced de icing system. Now, you say to yourself, well, there's been a lot of de icing systems on wind turbine blades. In fact, Rosie has worked on a number of them for LM. But this one's a little bit different. So it It uses a kind of a matrix setup of thermal heating areas arranged in sort of series and parallel connections, and it creates overlapping heating zones that can be very precisely controlled. Now that is very beneficial because a lot of times you More temperature, more heat towards the tip than you do at the root. So you would like the temperature to be graded up towards the tip. It's kind of hard to do a lot of times. But in this situation, you can adapt it to the situation. And this seems smart, but I haven't seen it implemented. And I know Siemens Gamesa owners. Like the icing system. So maybe this is coming out in the near future, Phil. Phil Totaro: Yeah, this would be interesting because this is very different than your conventional like blown air solution, like Enercon and other companies use. Where you could have a scenario where you've got like hotspots and, and heat concentrations at different points along the blades, particularly where you have ribs or bulkheads or something that would kind of get in the way of the airflow. a thermal heating mat with again, different zones where you can kind of trigger, on off to, to try and either prevent ice accretion or actually provide deicing for the blade. So it's, it's a really interesting approach in that it gives you more granular control over where you want to be able to, to de ice and again, based on ice thickness, and you can, monitor your Phil Totaro: performance, or you might have a more sophisticated system that actually monitors how much ice is still stuck on the blade. So. The, the implementation of this I think would be welcome. And it's probably something that, I mean, heating mats are almost inevitably, they do introduce a certain amount of challenges, especially with lightning interactions. But generally speaking, they are a good way for wind turbine blades to to be de iced. So hopefully this does make its way into more commercially available products in the future. Allen Hall: Well, it looks like it will save somewhere between 20 and 50 percent of energy consumption to, to heat the blade. That would be remarkable if you could make a, even a 10 percent change in the amount of power required to heat the blade up. Going to 50 percent would be astounding. And that makes me think you're going to see this, this patent idea Phil Totaro: show up pretty soon. I mean, to be blunt, like, and I'll do respect to Enercon that pioneered a lot of this technology, but volumetric heating is just wildly inefficient, so it's like, something that's a more, cost efficient and thermally efficient solution is probably desirable. Allen Hall: Our next patent is from Vestas and this. Seems like a relatively simple idea, but it evidently isn't because they were able to patent it. So,
