A group of secondary school students in Nigeria have built an electricity-generating system that can be powered with urine.
The students, all girls aged between 14 to 15 years old created the power system and ran it for six hours with only a litre of urine at the Maker Faire Africa.
The girls Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15) created a system in which urine is put into an electrolytic cell, which separates out the hydrogen. The hydrogen then goes into a water filter for purification and goes 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 then pushed into the generator to produce electricity.
Duro-Aina, one of the young inventors, explained that the invention was borne out of their interest to create a clean energy generating set adding that the main motivation for the project was hearing about an increase in carbon monoxide deaths from fossil-fuel powered generators put into use due to a failing Nigerian energy grid and wanting to “make a generator that won’t release carbon monoxide.”
