OK, guys. Everybody pee in the cup - pour it in the tank, turn the
ignition to fire off the electrolysis that frees the hydrogen from the
nitrogen in the urea and supplies instant hydrogen to the engine. Pee is
simple and safe in the gas tank - hydrogen is not. So pee is the fuel of
choice. It's being tested right now somewhere here in the US at a
university . University of Ohio I think.
