Nigerian teenage students invents urine-powered generator

Four secondary school students, Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15) invented a urine powered generator.

The girls, at the Maker Faire Africa exhibition in Lagos, displayed the urine powered generator which ensures that 1-litre of urine generates 6 hours of uninterrupted electricity supply.

How the urine-powered generator works:
1. Urine is put into an electrolytic cell, which separates out the hydrogen.
2. The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.

3. The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.
4. This purified hydrogen gas is pushed into the generator.

The 4th Maker Faire Africa event was held in Lagos, Nigeria, between November 05 - 06, 2012
