Nigeria :Nothing is really a waste in the real sense of the word. Almost anything one can think of is reusable. Everything has some value one way or the other. This was what four teenage secondary school girls in Lagos set out to prove.
Making its debut at maker faire africa 2012 in lagos, nigeria, a group of teenage girls have developed a urine-powered electricity generator.
The system works by separating the hydrogen from the yellow stuff with an electrolytic cell. A gas cylinder then pushes the hydrogen into a liquid borax container,removing the moisture from the substance, resulting in a purified version of the gas that can be used for fueling the machine.
Conceived using one-way valves as a security measure, the energy source provides six hours of electricity for every liter, which is not too bad considering how often humans go to the washroom.
The generator was unveiled at last weeks Maker Faire in Lagos, Nigeria, by the four teens Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, all age 14, and Bello Eniola, 15.
So how exactly does the urine-powered generator work?
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.
