99% sure there's a motor in the middle. No other reason for it to be that thick there, especially since less weight would let it turn faster.
Should make the rotor, at least the center part if the copper is necessary, out of clear plastic.

umm none of these are WORKING.. the wheel one where they move the magnet back out at the end of rotation looks interesting.. if they could make a device built in that mechanically moves the magnet at the end it would work.. my guess is that it would probly take more energy then that thing has behind it to do so.. so in conclusion none of these work.. bye
