South Korean Students Poop To Earn Cryptocurrency and Power Building

At South Korea‘s Ulsan National Institute of Science and Technology, students can now defecate to earn cryptocurrency and help power a building.
UNIST urban and environmental engineering professor Cho Jae-weon designed an eco-friendly toilet that harnesses human feces to produce biogas and manure. Dubbed the BeeVi Toilet (a portmanteau of the words bee and vision), the innovative toilet utilizes a vacuum pump rather than water and is connected to an underground tank where microorganisms break down waste.
The microorganisms create methane that can be used as a sustainable source of energy in a variety of ways. An average person defecates 500g a day which roughly converts into 50 liters of methane gas or 0.5kWh of electricity which is enough to drive a car 1.2km (0.75 miles).
“If we think out of the box, feces has precious value to make energy and manure. I have put this value into ecological circulation,” said Cho Jae-weon.
Additionally, students that use the BeeVi Toilet can early 10 Ggool (honey in Korean) a day, a cryptocurrency dispensed by the eco-friendly toilet that can be used on campus to purchase products.
