making its debut at maker faire africa 2012 in lagos, nigeria, a group of teenage girls have developed a urine-powered electricity generator. the system works by separating the hydrogen from the ‘yellow stuff’ with an electrolytic cell. a gas cylinder then pushes the hydrogen into a liquid borax container, removing the moisture from the substance, resulting in a purified version of the gas that can be used for fueling the machine. conceived using one-way valves as a security measure, the energy source provides six hours of electricity for every liter, which isn’t too bad considering how often humans go to the washroom.
