I work at a national lab and there were three old wind tunnels on site. I was the last one to work in the buildings so got quite familiar with them. They’ve been demolishing them to put up a new (unrelated) lab. That one in the picture was used by the McLaren F1 team in the 80s and 90s, who installed a rolling road. Power was actually still there when I was using the building but there were too many interlocks and I couldn’t quite figure out how to fire them up :(
The fans were about 3.5m diameter on 250kW motors. I thought about trying to take one out but it was always going to be a matter of what I was going to do with it and where the hell I could put it!
I can’t help any more. They just demolished my one :(
