Last winter I noticed that I had accumulated a sizable collection of small 5 volt DC motors which I had salvaged from a bunch of old CD ROM drives.
Trying to think about what I could do with these motors, I played around with them a little bit to come up with some ideas. It was during these experiments that I realized that when one of these motors were hooked up to a solar cell that I had laying around, it seemed to spin the motor at a very good rate. From there, an idea was formed.
