Your pants (TGW) – This little MP3 Player here doesn’t need to be charged. It powers itself.
Unveiled at the Greener Gadgets convention this year, this self-power music player invented by Zhiliang Chen is powered by movement. Shake it or attach it to your pants and go for a walk and it will charge itself. As Mr. Sameer over at Ecofriend points out, there are some R-rated applications for this gadget.
The same technology has also been applied to a flashlight.
