The excrement is converted into a digital currency. 💵
. Now, there's a new South Korean toilet that might be even more impressive.
The toilet turns excrement into energy and even allows students to purchase stuff with the amount of poop they produce.
The toilet employs a vacuum pump to draw waste into an underground bioreactor, which features microorganisms that break down the waste to methane. This then becomes a source of energy for the building, powering a gas stove, hot-water boiler, and solid oxide fuel cell. Its special pump reduces water use.Cho has conceived a virtual currency called Ggool, which means honey in Korean.
All in all, it's a superior eco-friendly toilet that lets students at the university earn money from pooping in order to buy products at the university. Postgraduate student Heo Hui-jin purchasing items at the Ggool market told Reuters,"I had only ever thought that feces are dirty, but now it is a treasure of great value to me. I even talk about feces during mealtimes to think about buying any book I want.
