Solar-Powered Toilet Transforms Human Waste Into Fertilizer Bricks
Concentrated solar energy scorches human feces with 700 degree heat.
Sol-Char Toilet, created by researchers at the University of Colorado, proves that human waste is anything but useless. Powered by the sun, it transforms excrement into biochar, a material that can be used as fertilizer or fuel. Biochar is not only an ideal fertilizer, but it can help to reduce pressure on the world’s finite natural resources.
