Why is this guy smiling? Unlike your Zero, his electric motorcycle is solar powered. To build the bike, Jim Corning started with his wife's Ninja 250, adding a front wheel cover and extending the back end for aerodynamics. The motor is powered by lithium-ion phosphate batteries, which are recharged by four 800-watt solar panels mounted to the roof of his house (so it's not like you can just sit out in a field somewhere and charge up). The current design gets up to 70 mph and a range of about 50 miles: no power cord required. Want to make one yourself?
