Four Nigerian teenage girls develop a urine-powered generator

Four Nigerian teenage girls - Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15) have created something truly incredible, even if it's a little dangerous..:-).

The girls invented a urine powered generator which was showcased at this year's Maker Faire Africa held in Lagos a few days back. Continue to see how it works....

According to Maker Faire Africa, an annual event which showcases inventions, the system works like this:

• 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.
•  1 Liter of urine gives you 6 hours of electricity.
