Now you never have to worry about your cell phone or iPod running out of battery on long cycling trips, thanks to Filipe Lima and the Energysport. The Energysport is a charger that uses the kinetic energy of a bike wheel turning to charge a power pack, which can in turn be used to charge up your gadgets.
The Energysport is still a concept, but with green energy and kinetic energy especially getting more and more looks these days, I'd wager that Energysport could go from concept to reality fairly quickly.
