Nigeria Schoolgirl pee power energy generator – uses just pee to generate electricity
http://www.overunity.com/13101/urine-powered-generator-from-africa/
This is a new system designed by 4 schoolgirls from Nigeria, Africa with the help of their teacher to
get an electrical generator system running on just ONLY Urine !
They used electrolysis to split Urine ( pee ) into hydrogen and
clear it up via a liquid borax solution and then run a generator to produce the electricity to
run the electrolysis…
So it seems this is a selfrunning system only using up the pee !!!
Urine-powered cars, homes and personal electronic devices could be available in six months. Using a nickel-based electrode, scientists can create large amounts of cheap hydrogen from urine that could be burned or used in fuel cells. One cow can provide enough energy to supply hot water for 19 houses.
One molecule of urea, a major component of urine, contains four atoms of hydrogen bonded to two atoms of nitrogen. If you place a special nickel electrode into a pool of urine and apply an electrical current, hydrogen gas is released.
A urine-powered vehicle could theoretically travel 90 miles per gallon.
Using urine as a source of fuel may sound like a bit of a stretch, but it’s actually quite ingenious.
It’s based on the use of hydrogen, the most abundant element in the universe. Hydrogen has been called “a renewable, versatile, simple sustainable domestic energy” because it can be produced from tap water to generate power for homes and cars.
However, one of the hurdles facing this alternative fuel source is that hydrogen gas requires high pressure and low temperatures to be stored. It becomes somewhat easier to store when it’s binded to oxygen to create water, but even then it still requires large amounts of electricity to be released.
The Ohio University scientists who developed the urine technology found that attaching hydrogen to nitrogen in urine allowed it to be stored without the strict requirements of ordinary hydrogen, and allowed it to be released with less electricity (0.037 volts versus 1.23 volts needed for water).
So it is very interesting that you can already split urea at 37 millivolts…
No wonder this urine splitting could be made so efficient in an electroylsis cell !
You just need so much less power for splitting pee than water…
