Years ago I saw a show about a compilation of metals made into a disk. When cooled to zero kelvin it both attracted and replused like a magnet, two disks would stay 2" appart and if you spun one it would rotate forever. If done in a vacuum it would be perpetual. They talked about the possibility of connecting a generator (like a bike light) to it, but the friction would slow it down, but the idea was cool. If tempurature rose just a little, the suspended disk would lose its' attraction and repulsion properties and it would fall.
Coolest thing I've ever seen
