4 Nigerian girls invented a generatorthat produces electricity using urine as fuel

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).
1 Liter of urine gives you 6 hours of electricity.
The system works like this:
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.
Along the whole way there are one-way valves for
security, but let’s be honest that this is something of
an explosive device
that is very good development!  let's buid our countrry as a great nation. SOURCE;AFRICAN LEADERSHIP
