"If we think out of the box, feces has precious value to make energy and manure."
A researcher at a university in South Korea has devised a toilet that turns human waste into power, Reuters reports. As a bonus incentive, each use rewards, uh, poopers with a small amount of digital currency that they can trade in for a coffee or a cup of noodles on campus.
The toilet first pumps your excrement into an underground tank, which means it uses less water right off the bat when compared to a traditional toilet. Microorganisms then break down the waste into methane, a usable source of energy.
In short, it's a delightful new method of turning sewage into power.
"I had only ever thought that feces are dirty, but now it is a treasure of great value to me," a postgraduate student Heo Hui-jin who's both earned and spent Ggool, told Reuters. "I even talk about feces during mealtimes to think about buying any book I want."
