Forget battery-powered vehicles. A professor at Ohio University claims to have figured out a way to turn pee into fuel. Now we're talking progress!
According to New Scientist, humans produce 10 billion liters of urine each day—enough to power the world. And with gas prices on their way to $4 a gallon again, it's time to come up with truly alternative resources.
Gerardine Botte, a professor of chemical and biomolecular engineering, says that two compounds in urine, ammonia and urea, could be a source of hydrogen, which would power specially adapted cars. The fill-up process sounds a little unpleasant, but imagine making a roadstop and emptying your personal tank to fill up your Jeep. Sweet!
