Workout and charge your cell phone

Splunch writes – “Nineteen-year-old Pankaj Sharma from India has invented a pair of shoes that can charge your cellphone while you are on the move – literally! By simplying walking, your cellphone can be charged within an hour’s time. The way it works is pretty simple. A dynamo is attached to the shoe, which converts the mechanical energy, generated by the act of walking, into electrical energy. A bridge rectifier converts the AC current into DC current, producing five to six volts of electricity for charging your phone.” – Link.
