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, affordable
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’ school
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, 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. The girls say that one litre of urine gives six hours
of electricity.
