A trip to the toilet could be worth some coin in South Korea because at the Ulsan National Institute of Science and Technology, a professor is putting that waste to good use by powering a building. Professor Cho Jae-weon designed an eco-friendly toilet called the Bee-Vi. It saves water by sending the excrement to an underground tank where it’s broken down for methane that’s being used as an energy source.
