enegy from cow urine?

[joel77]

I am not sure if this is "free Enegey" but its quite interesting.
aperantly they can produce hydrogen and therefore energy from urine
while you would still need to mine the components for the electrodes etc it could have have interesting applications in agraculture etc,
however i cant see myself peeing in the fuel tank every time i run out of gas though.
but if it meant i could forgo the use of fosil fuels i would be happy to use to urea as a source of energy
