Good point, ok if you made the sails out of plastic like I said then the whole upper section could be plastic including the shaft, maybe strong PVC or something, that way you would have a way of attaching the magnets as in George Greens motor. You could use an epoxy or something similar to attach the magnets in a circle to create that effect.
Maybe like a 1 inch PVC pipe inside of a 2 inch PVC pipe with the ring of magnets around the 2 inch pipe and the center magnet in the 1 inch pipe. I just say use plastics because they're cheap and easy to attach magnets to. Aluminum would be ok if you can figure out how to attach the magnets.

I would like to buy their base with all the magnets and coils installed and make my own top section, then add the George Green set up on the top section somehow. I like their mag-lev set up!
