Hi Guys,
Just read something interesting and am posting it here for those who are interested to investigate further.
"Urine can be used as a base material for the production of hydrogen (http://en.wikipedia.org/wiki/Hydrogen).[39] Unlike water, urea has four hydrogen atoms per molecule and has these atoms "less tightly bonded" than the hydrogen atoms found in water molecules."
Be responsible
