Pee: it’s not just for toilets anymore! Scientists at Ohio University say urine from humans and animals can be used to make hydrogen, which creates the hydrogen gas used in fuels when an electric current is sent through it. The power of pee could hypothetically be used to get 90 miles to the gallon on a car and the pee from one cow could create enough energy to heat water for 19 homes, the scientists say. No word yet on how expensive or smelly it might be. But, hey, whatever works to be green, man. [NY Daily News]
