James May's Big Ideas: Power to the People

James May tries to find smarter, brighter and bolder ways of powering the planet. He sets off on a global search to find people who share his dream. This search takes him from Guildford, where he takes a solar powered car to its limit, to Holland, where he meets the first Dutchman in space, who has put away his rockets and has swapped them for kites. Finally, James seeks out some modern-day alchemists, who offer the promise of allowing him to drive his car on petrol conjured out of thin air.
