They were popular on British bicycles in the 60's and early 70's. A "generator" built into the hub of a 26 inch bicycle wheel. Turn one of those babies into a windmill! Actually I have some experience with windmills. I wish you the best of luck, but gently suggest that unless you have 20mph winds you'd do best to consider other methods. Unless all you care about is kinetic sculpture, not electric power. How about solar power? Even if you are clouded over you'll get output from amorphous cells. If you get any full sun you'll do better with regular crystalline types. Cheers, Bob
