GreenTech: Power your own music
Man, I love dancing. Dancing in the street, dancing in the dark, dancing all night and still begging for more. During the holidays I put on a red suit and stand on the lawn shaking it to "Jingle Bell Rock" like one of those electric dancing monster Santas.
Anyway, that's why I'm excited as all get-out about this concept gadget that was a notable entry in the Greener Gadgets design competition. Zhilian Cheng, a designer out of Hong Kong .has come up with a music player that uses human kinetic energy for power. What that means is that as long as you're in motion, this proposed MP3 player would be continually recharging.
If you're not as enthusiastic as I am about making a public spectacle of yourself, you don't have to dance - jogging or even walking should do the trick too.
Not recommended for couch potatoes.
