Foot Pump Phone Chargers
Festival goers at Glastonbury, in the U.K., can charge their cell-phones through using a standard airbed foot pump, the type normally found all over festival sites. The Orange Gotwind power pump's turbine is rotated at speeds of up to 2000 rpm from the air flow generated by the foot pump, this turbine then directly drives the small but powerful alternator. A 5 minute phone call will require approximately 1 minute of foot pumping.
