Many folks run and move around every single day to burn calories and stay fit. Wouldn’t it be nice if you could generate power for your mp3 player as you run? These Dancepants offer you just that. Created by Lithuanian designers Inesa Malafej and Arunas Sukarevicius, these pants use kinetic energy to generate power for your mp3 player. The kinetic module is attached at the pants leg with a connection to your mp3 player. Not sure where you can buy these but the idea is worth exploring.
