Charger batteries as you walk
 
This is an interesting gizmo. It charges batteries as you walk. I assume it uses the kinetic energy from bouncing up and down like those shaker flash lights. I should get my wife one of these. She's on her feet all day long and could probably charge a dozen batteries a day. :)
