The 4 girls -- Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, and Bello Eniola -- remarkably figured out a way to convert one liter of urine to fuel that can produce up to six hours of electricity from their generator.
The urine-powered generator works uncomplicatedly. Initially, urine is put into an electrolytic cell to separate out the hydrogen. It gets purified through a water filter until it gets pushed into the gas cylinder where the filtered hydrogen is pushed through another cylinder that contains liquid borax to remove moisture from the gas. The hydrogen is then pushed into a power generator as the final step.
