Scheduled to be unveiled Summer 2009 in Glastonbury is this nifty gadget that allows users to extend their mobile phone battery life even if there's no electrical outlet or car charger available.
Made by GotWind, it harnesses kinetic energy from an air bed foot pump, which in turn drives a turbine within the Power Pump. Then, the energy is converted into an electrical current which can recharge a mobile phone battery. The device will be showcased at the Glastonbury Festival, Somerset (UK) at the end of June. Now that's a cool eco gadget!
