Urine powered generator from Africa

[hartiberlin]

Hi All,
here is a new system designed by 3 schoolgirls from Africa with the help of their teacher to
get an electrical  generator system running on just ONLY Urine !

They tell you in this article,

that 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 !!!


I just have googled for other pee electrolysis processes and I found this here:

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...
I will try it soon.

If anybody finds a real video of it,
please post this.

Many thanks.

Is there any one know if the voltage applied to the electrolysis of pure water is proportional to the gas produced or is it non linear?

Urea is a fertalizer sold in a few different forms.In bulk it is very cheap.http://www.alibaba.com/showroom/urea-crystals.html
  If ordinary water can be recombined with it then it's viable. Just keep in mind it is also a component of gun powder so you'll most likely get yourself put on a list if you buy it in quantity. I read an artical about the old western pioneers a long time ago and wondered how they managed to cart enough gun powder to make the trip and sustain themselves for years with out regular shipments of ammo and shot to hunt with. Turns out making powder is actually easy and can be done with stuff you find along the way in nature. I never would have thought of it as an electrolite. Now you have me thinking about its possible uses in batteries, capicitors, solar cells. Ahhh it's gonna be a pissy day. Thanks
