We thought we were supposed to have fusion-power for our DeLorean by now but it perhaps urine-power is just around the corner instead. [Gerardine Botte] has been working on creating hydrogen from urine, the world’s most abundant waste product. The voltage needed to break apart the urea atoms is less than half that of water, and the way we see it, you’ve had the added benefit of already using the water once before creating the fuel. [Gerardine] also makes the point that urine has phosphorus in it which could be another useful outcome of the process because it is needed as an agricultural fertilizer. Does this mean that you can repay your designated driver by fueling up his vehicle after a night at the bar? It’s probably better than doing the same for the battery of your cell phone.

Hackers produced the first vegetable-oil powered vehicles so we’re throwing down the challenge of producing the first pee-and-go automobile. Good luck and wash your hands when you’re done.
