Urine-powered generator unveiled at international exhibition Urine is put into an electrolytic cell, which separates out the hydrogen. The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder. The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas. This purified hydrogen gas is pushed into the generator.
frankly, I don't see the conservation of energy... i.e. does the electricity generated exceed the electricity needed to power the electrolytic cell?
