Tensairity, and a tensairity torus idea

Yes. I think that’s a good idea. There are already similar designs but then made out of steel or aluminium. See: Innovative Wind Turbines - An Illustrated Guidebook (Vaughn Nelson) For example: Turbine Specifications - BarberWind Turbines

Note that those designs are mostly rim drive.

I don’t see the need to immediately think about MW installations. Just make something in your garage first.
