A Minnesota man who invented a rocket-powered toilet and a jet-powered coffee pot has come up with a motorcycle that runs on beer. Ky Michaelson says the beer-powered bike has a 14-gallon keg with a heating coil instead of a gas-powered engine. The coil heats the beer to 300 degrees, then super-heated steam in the nozzles propels the bike. Michaelson said he's not a drinker so he can't think of any better use for beer than to run his motorcycle. See video below.
