Eco Factor: Eco-friendly generator provides electricity for portable electronic devices.
The movement of the wheels of a bike has been used to generate electricity in many ways. The idea gets more attractive as people get more dependent on portable gadgets. While Nokia has already unveiled a bike charger for its mobile phone users, a passionate DIYer has created a USB bike generator that can help you charge other mobile phones as well.
The device corrects heat inefficiency in an older design by substituting a stepper motor. The device provides 5W of power, which can help you charge your handheld devices. Check out the complete DIY instructions at Instructables.
