Thinking outside the box!!! A group of school girls from Nigeria figured out a way to use a litre of urine as fuel to get six hours of electricity from their generator.

Fourteen-year-olds Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, and 15-year-old Bello Eniola displayed their invention at Maker Faire Africa in Lagos, Nigeria, an annual event meant to showcase ingenuity.

Urine is put into an electrolytic cell, which separates out the hydrogen. The hydrogen goes into a water filter for purification, and then into a gas cylinder, which looks similar to the kind used for outdoor barbecue grills.

The gas cylinder pushes the filtered hydrogen into another cylinder that contains liquid borax, in order to remove moisture from the gas. Borax is a natural mineral, commonly used in laundry detergent.
The hydrogen is pushed into a power generator in the final step of the process
Kudos ladies!!!
