Possibly one of the more unexpected products at Maker Faire Africa this year in Lagos is a urine powered generator, created by four girls. The girls are Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15).
The generator is on display at an exhibition in Lagos Nigeria where people from the tiniest villages to those from big cities are talking about making stuff. This is part of an initiative by ‘Maker Faire Movement’ which seeks to showcase how traditional handicrafts can be a solution in the wake of expensive robot.
Their invention ensures that 1 Liter of urine gives you 6 hours of electricity.
The system works like this:
1. Urine is put into an electrolytic cell, which separates out the hydrogen.
2. The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.
3. The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.
4. This purified hydrogen gas is pushed into the generator.
