African teenagers invent a urine-powered generator

Hmmm<p>&#62;The system works like this:<p>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.<p>Don't electrolytic cells need electricity to split water into hydrogen and oxygen? Also why have they got 2 automotive fuel filters on top of that tank of red stuff and why are the filters venting to the atmosphere? Isn't that wasting their precious hydrogen? 6 hours of elecy from each litre of pee? I'm certain that if pushed I could generate about a litre an hour and thus this machine would power my pc , my router and charge my iPad for free.<p>Or not because this story is bullshit. Seems others think so too <a href="http://nathan-lee.com/blog/2012/11/07/urine-powered-generator-theyre-taking-the-piss/" rel="nofollow">http://nathan-lee.com/blog/2012/11/07/urine-powered-generato...</a>

They use an electrolytic cell to extract the hydrogen from the urine...<p><a href="http://en.wikipedia.org/wiki/Oxyhydrogen#Fringe_science_and_fraud" rel="nofollow">http://en.wikipedia.org/wiki/Oxyhydrogen#Fringe_science_and_...</a><p>&#62; the energy required to split water molecules exceeds the energy recouped by burning it
