Charge your cell phone while you walk

A 19-year-old Indian from Himachal Pradesh has invented a pair of shoes fitted with an appartus, that charges a cell phone while you walk, reports CNN-IBN via Techtickerblog and digg.

"The mechanism is quite simple - a dynamo attached to the shoe converts the mechanical energy produced by the pressure of the foot on the sole into electrical energy. A bridge rectifier further converts the AC current into DC current and produces five to six volts of electricity.

For this invention, Pankaj won first prize last July in the student category from the National Innovation Foundation".
