In 2012, four high school teenage students – Adebola,

Abiola, Toyin and
Eniola showcased a thoughtful and practical
innovation that
warmed the
heart of Africans and the international
community. This
invention was a
urine power generator which could provide safer,
and more
access to electricity.
The invention which was first showcased at the
Maker Faire
Africa annual
pan-African conference was born out of the girls’
chemistry lab
and could create 6 hours of electricity with 1
Liter of urine.
Furthermore this girls said The system separates
urine into
nitrogen, water and

hydrogen. Urine is put into an electrolytic cell,
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. The girls say that one litre of urine
gives six hours
of electricity.
