Backpack generates power

A backpack that converts a plodding gait into electricity could soon be charging up mobile phones, navigation devices, and even portable disc players. The backpack design converts mechanical energy from up-and-down movement of the backpack’s cargo to electricity during normal walking. The simple magnetic coil generator is similar in principal to those seen in hand-cranked radios, flashlights that work after a rhythmic shaking and other devices.
