A New (very unusual) Way Of Attaining Electricity

I recently came across an article on treehugger about an innovative
invention made by a group of teenage girls in Africa that produces
energy that uses an unusual (kinda gross) ingredient that might somewhat
shock you.... *** drum roll please***.... human urine..... yea i know,
takes recycling to another level...
but it does work perfectly and in fact, a liter of urine can produce
six hours of electricity
Below, I have added a chart showing how their invention actually works:

• 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.

This type of invention can really change the way we look at human waste.
and how it can be recycled to produce energy that we use on a daily basis
This could really be an invention that can become globally innovative and
useful in many households and commercial spaces.
Hopefully the world population will pee enough to meet electrical standards
and demand....
