A prison in Rwanda is home to a unique project that converts the feces of prisoners into a reusable fuel to operate prison facilities.
The process requires putting a given amount of human or other animal waste into a "digester," which ferments it using bacteria to release methane gas that can be captured and then burned as fuel. Attached is a "compensating chamber" that replenishes the supply of bacteria to keep the operation self-sustaining.
He added that the Rwandan prisoners are not put off by the idea of using the byproduct of human waste to cook.
"Our people are very adaptive," he said. "They see it working; they want to use it."
And no, I'm not shitting you.
