Four teenage girls from Africa showed off their unique creation at Maker Faire in Lagos, Nigeria. The Faire is a constant magnet for people who want to show off their inventions and practical creations. Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin and Bello Eniola created something the world had never seen before. They invented an electricity generator fuelled by a single litre of urine.
You probably wonder how on Earth could urine produce electricity? Well, the key is the hydrogen in the urine.
The uncommon “fuel” is put into a special electrolytic cell. The cell separates out only the hydrogen from the liquid. The separated hydrogen is then purified into a water filter and goes into a gas cylinder. Another purifying takes place into a cylinder of liquid borax. The borax removes the hydrogen’s moisture. Finally, the purified hydrogen gas is pushed into the generator.
After the process of purifying a litre of urine is completed, the generator will run for 6 hours.
