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… Link to this video. https://www.youtube.com/watch?v=f48zowFhVFA
