Nigerian Teenage Girls Create Urine-Powered Electrical Generator
By Anthea Quay, 09 Nov 2012
Four Nigeria-based 14- and 15-year-old girls Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin and Bello Eniola created a urine-powered generator.
Unveiled at the Maker Faire Africa in Lagos, the device is able to provide six hours of electricity with one liter of urine.
Urine is first put into an electrolytic cell to separate out the hydrogen.
Hydrogen goes into a water filter for purification and gets pushed into a gas cylinder.
The gas cylinder pushes the hydrogen into a cylinder of liquid borax to remove the moisture from the hydrogen gas.
And finally, the purified hydrogen gas is pushed into the generator to create electricity.
Currently, the device is not completely stable, and can be quite explosive—but it bears some form of hope for turning human waste into something useful, to help save the earth.
Would we be peeing for electricity in the future?
