Eco Factor: Pedal-powered USB gadget charger.
Solar-powered chargers do promise to give your gadget a green charge every time, but sun isn’t a reliable source of energy unless you’re aboard the International Space Station. A team of students have created a much more reliable and a green way to charge your USB gadgets using your bike as the source of energy.
The mod makes use of a Maxon motor rated at 6V. The $275 motor might be more expensive than your bike, but it does help you charge your loved gizmos in a green way. The motor is mounted close to the rear brake mount where the motion of the wheel brings the motor in motion. This motion generates electricity which can then be fed into any gadget which needs some juice. Head over to Instructables for the complete DIY instructions.
