Who says girls detest science? Not anymore, after seeing this electricity generator invented by four entrepreneurial Nigerian teenagers. Possibly, the urine powered generator will be one of charming yet unexpected products at Maker Faire Africa this year in Lagos.
The generator can produce six hours of power from 1-liter of urine. The girls, Duro-Aina Adebola (age 14), Akindele Abiola (age 14), Faleke Oluwatoyin (age 14) and Bello Eniola (age 15), are an inspiration for renewable energy developers everywhere.
The device isolates valuable hydrogen from pee so as to use it as an energy source. An average person produces about two liters of urine a day, so an individual can easily operate the girls’ generator.
One liter of urine will at first be put into an electrolytic cell to separate hydrogen from it. The hydrogen is then purified with a typical water filter, and extracted into a gas cylinder. After that, the hydrogen is again compressed in another cylinder of liquid borax for removing any excess humidity from the hydrogen. The pure hydrogen is now ready to be used in the generator.
The generator is not a stand-alone generator as it needs electricity to power the electrolytic cell and above all, containing any amount of the pure gas is risky as the Hydrogen is explosive. Still, it’s a pretty impressive achievement for the girls.
