A urine-powered generator
What’s the Idea?
Four young Nigerian girls have invented a generator that runs on urine. The invention was first displayed in Lagos in 2012. A litre of urine can be used as fuel for generating six hours of electricity.
Power outages happen many times a day in Lagos, and not everyone can afford to have a backup generator. It’s possible that the girls’ idea can be applied beyond just power generators, as gasoline-powered internal combustion engines can be converted relatively easily to run on hydrogen.
Bringing pee power to the people
The system separates urine into nitrogen, water and hydrogen. 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.
