Bike-Powered Generator Disguised As Patio Furniture [Video]
An Instructables member created a generator built from scrap wood and an old treadmill.
An Instructables member who goes by the name KlockworkKevin has built a bike-powered generator that he can simply pack up and convert into an unassuming patio table when not in use.
The generator is made mostly from recycled materials and the inventor used scrap wood for the table cover and pedal generator and an old treadmill that he found on the street for the bike. He purchased a Deep Cycle Marine Battery and a 400-watt inverter, and built a voltager regulator from electrical components from scraps.
