Calling all lawnmower fans! Wouldn't it be great if you could charge your cell phone or MP3 player the same way you'd start up a gas-powered mower?
If you played with a Wooly Willy as a child, you've experienced the small pleasure of dragging iron filings with a magnet to give a bald-headed man a hairdo, beard, mustache, and/or fuzzy eye patch.
