And we are in Roskilde, Denmark at the 5th International Symposium on Leading Edge Erosion and Wind Turbine Blades. And I'm here with Nicholas Gaudern of PowerCurve and Rodolfo Meleiro of Arthwind. So we have a world perspective here on leading edge erosion. We have Europe. Brazil, which is a lot of wind energy there. Thank you for being here and I'll try to cover the America as best I can. So this has been a really interesting conference. It's held at DTU which is, this is a wind energy center. So this conference has been organized and it has international flavor to it. We saw presentations from India, Denmark, obviously there were German. Yeah. Presentations, Japan, China u. S. Sandia has been here. So there's a paper from Cornell today. So there's been all sorts of people worried about leading edge erosion. And I think it's a really hot topic. And that's the reason why I came to, to see the action here, because there's. So much that we don't know. And I figured if anybody does know it's a DTU, so it's time to get over there and to find out what's going on. So this whole podcast is really to discuss what we have seen and heard and try to figure out what the state of the industry is and where it needs to go. And just first impressions, really One of my first impressions, I'll just start. One of my first impressions was we have a long way to go. Yes, that we don't know a lot. Yeah, and I wish I had been shocked so far So we're at the end of day two and day one was pretty intensive on this or the mathematical Computational side. Nicholas Gaudern: We don't know a lot. We've had a lot more materials as well today So I think it's nice that we have that really cross disciplinary approach here. So we've got materials. We've got structures. We've got data We've got metrology, meteorology, aerodynamics So it is bringing all of these expert field together which I think is really important. There's also the risk that there's a lot of noise, because obviously there's issues to be resolved in all of these different fields. And then, it may make it a little bit harder to focus on what really matters I think. Allen Hall: There's a lot of data smoothing that's happening at the minute, from what I can tell, and different approaches to data smoothing, and I'm not even sure. Everybody has settled on that. Nicholas Gaudern: No, and I think we had like a discussion at the end of the day yesterday, like a shouting across the lecture theatre kind of discussion at the end of the sessions. And I think what was clear is there is more of a consensus about the AEP losses that we're seeing, which is important. And that's really helpful because I think if you start seeing big scary numbers 15, losses, sure, those might exist in a very extreme scenario on a very particular type of turbine, but I really want to make the point here that is not the norm at all. We wouldn't have an industry if 20 percent AEP eve...
