There were many innovative designs at this year’s Maker Faire Africa in Lagos, Nigeria, but one in particular has caught the world’s attention. 14-year-olds Faleke Oluwatoyin, Duro-Aina Adebola, Akindele Abiola, and 15-year-old Bello Eniola have created a brilliant urine powered generator, transforming human waste into power. The system is able to generate six hours of electricity from one litre of urine.
Here’s how it works:
- 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.
