Crypto toilet in Korea
An engineer and lecturer from Korea turned a university toilet into a power plant that has a crypt. An environmentally-friendly toilet produces energy and gives students cryptocurrency. Every student who goes to this toilet gets the opportunity to buy coffee or snacks in the dining room.
Who created the installation?
The installation was created by a professor of urban engineering and environmental engineering at the Ulsan National Institute of Science and Technology (UNIST). Environmental scientist Cho Je-on has combined a university toilet with a laboratory that uses excrement to produce biogas.
If you think outside the box, feces are of great value for biofuel and energy production. And I put this environmental value into circulation and in his opinion, the average person produces about half a kilogram of material per day. It can be converted into 50 liters of methane, which is able to generate half a kilowatt of energy. This is equivalent to moving the car at a distance of 1.2 km.
How it works
The system is called BeeVi and uses a vacuum pump to send feces into an underground tank. Therefore, the installation has another bonus – it helps reduce water consumption. In the tank, waste is taken by microorganisms, converting them into methane. It burns in a gas installation that heats a boiler with water. The result is an unexpectedly large amount of energy.
And what a cryptocurrency
In addition, Professor Cho created a virtual currency called Ggool. Translated from Korean means “honey”.Everyone who uses an environmentally friendly toilet earns 10 Ggool a day. Students can use this currency to buy small goods on campus: from freshly brewed coffee to instant noodles, fruits, and books. Students receive crypto in the store by scanning a QR code to pay with Ggool.
