Allen Hall: Welcome to the Uptime Wind Energy Podcast. I'm your host, Allen Hall in the Queen City, Charlotte, North Carolina.



I'm here with Rosemary Barnes and. Australia Phil Totaro's in California and Joel Saxum's back home in Texas. We've all decided that we're not gonna talk about anything negative this week. That's good. Phil did have his pre-recorded rant. That's always good. So there, there is some dirt going on out there in wind, but I don't think we're gonna talk about it this week 'cause we just need a little bit of a break.



The top of the order is, uh, this Chinese flying wind turbine that looks like a Zeppelin, and [00:01:00] they have supposedly tested over in China, the world's largest airborne wind turbine, and it's called the S 1500. It's developed by Beijing's Saws Energy Technology, and it made us made in flight recently in Hames.



The, it looks like a Zeppelin and, and Rosemary, there has been a previous version of this that was around, but I don't think it went to anywhere, but it looks like it's what? It's about 40 meters tall, about 40 meters wide and about 60 meters long. So it's sort of this long tube. And inside of this tube they have 1200 kilowatt generators.



So they're creating power up at altitude, and they have a cable that bring down all the power. Down to earth. It's kind of like a heliostat and some of these, uh, other tethered systems. My question is, why are we trying that now? And especially in China where they have huge, massive wind turbine is [00:02:00]being built.



Why this? 



Rosemary Barnes: Yeah. Uh, I don't know. I often question why China makes certain decisions with investments they make. 'cause they have, um, yeah, invested in a whole bunch of. Out there technologies as well as dominating most of the mainstream ones. And, uh, what I usually come up with is that they've gotta try everything.



Strategy, very, very similar concept came out of MITI think that they developed it originally as a power generating thing, you know, basically just based on the idea that, um, wind speeds are way higher the further up you go. So they wanna. Get, get up into those really high, um, wind speeds that, you know,
