I s'pose it must work like an autogyro.
Either that or it is delivering bits for the new IOW wind farm.

That may have been a Walker Wingsail. I did some work for them back in the 80s when they were based in Hamble.
It was very efficent, but the rig kept falling down. They did not have the composit mast technology sorted back then.
It looks as if they are now in Plymouth.
