I was thinking about perpetual motion and perpetual energy generation when I got to thinking about magnets. Now, for the record, I don't think this would really work, but I can't think of why not, so maybe you guys can educate me on this. Open the attached image to look at while you read this. Now, the wheel is started in CCW motion. Each magnet on a spoke is drawn toward the magnet at the bottom (actually, two magnets, one on each side of the spokes -- see straight-on view), and thus speeds up the wheel a little as it gets closer; now, normally, each spoke-magnet would pass by the stationary magnet and then slow down, stop, and reverse direction, because it would seek to be as close to the magnet as possible, thus nullifying any increase in velocity. But, what if the other side of the magnet is blocked by a non-magnetic metal or other material? The spoke-magnet speeds up a little, passes by the magnet, and keeps going, as it loses its attraction to the big magnet. The next magnet approaches, adds some speed to the system, and passes... etc. One could even improve upon this design by putting a magnet on the other side that has the same polarity as the spoke magnets, thus repelling them as they pass by, and adding more velocity. Couldn't one draw power from this system in the same manner as a hydroelectric wheel being turned by water? Couldn't a large version of this generate some decent power?
