This Toilet Lets You Earn Cryptocurrency

Cho Jae-Won, an environmental professor at Ulsan National Institute of Science and Technology, a university in South Korea created a prototype of eco-friendly toilet which pays users a digital currency called “Ggool” for their contributions.

The toilet, called “Beevi” is connected to the university laboratory which turns users or students excrement into biogas and manure that serves as an additional source of energy for the university.

The toilet uses a vacuum pump which sends excrement into an underground tank. This procedure reduces water usage by a large percentage which makes it an eco-friendly toilet.

Every excrement is broken down by a special microorganism which turns it into a methane gas, which can be used to power gas stoves, water boilers, and solid oxide fuel cells.

According to Cho Jae-Won, every person usually produces around 500 grams of human waste a day, which when turned into energy, could produce 50 liters of biogas. This is enough to power an electric car.

The project also lets the contributors earn a cryptocurrency called “Ggool”, which means honey in Korean and each person who contributes to the project will earn around 10 Ggool a day.

Students can use the virtual currency to exchange coffee, instant cup noodles, fruits and books within the campus. Ggool is also integrated with QR codes and students can pick-up products from a shop and scan a QR code to pay using Ggool.

“If we think out of the box, feces have precious value to make energy and manure. I have put this value into ecological circulation.” the professor said.

Heo Hui-jin, a postgraduate of the university stated in an interview that he thought feces are dirty, but now he already has a different point of view about it that he even talks about feces even during mealtimes.
