Former NASA engineer Mark Rober (previously at Neatorama) was asked to charge a very powerful battery for an electric Volkswagen. He decided to make lemonade- a really serious lemon-powered battery, using 1232 lemons. After having as much fun with that many lemons as they could think of, he and William Osman got down to business. Lemons were not the only creative idea he had for charging the huge car battery. The Volkswagen supercar ended up winning the Pike's Peak Challenge, and set a world record, too! -via The Kid Should See This

An audacious plan. Though the power in a lemon battery doesn't come from the lemon but from the redox reaction of the metals.
