Cho Jae-weon, a professor of environmental engineering at the Ulsan National Institute of Science and Technology (UNIST) in South Korea, has designed a device that produces energy from human faeces, and rewards those who use it.
The device is a toilet that sends poop to an underground tank where it’s broken down by microorganisms into methane that “becomes a source of energy for the building, powering a gas stove, hot-water boiler and solid oxide fuel cell,” according to Reuters.
The toilet is called “BeeVi,” which is a portmanteau for “bee” and “vision”; the poop is delivered to the tank by a vacuum pump, which helps reduce the use of water for flushing.
