Fuel Cell Treats Wastewater and Harvests Energy
This is an interesting article pertaining to a new fuel cell engineered by the Israeli based company Emefcy. The fuel cell allows air to enter special containers that react with wastewater bacteria so that that the bacteria breaks down organic compounds. This releases electrons from the container which produces energy. It is being celebrated not as a substantial energy source, but it can offset the amount of energy used to clean wastewater.
