I saw this when Lego was showing off mindstorms here in Syd.
THEY (lego) claimed the setup was almost 100% efficent. i.e. one rotation of
generator = one rotation of motor. Have you got the wires hooked up the right
way? (assuming there is A right way!)
Has anyone else checked this out and can comment?
