Prototype Generates Energy While Cleaning Waste Water

Prototype Generates Energy While Cleaning Waste Water

Scientists have known about the potential of reverse electrodialysis for years, however, harnessing the power has proven somewhat problematic. Generating high levels of energy require plants to be placed at the intersection of fresh and salt water in order to get a chemical difference to provide a charge and therefore potential energy. REDs require a series of many membranes in order to work properly and to attain energy. However, using microbial fuel cells as the membrane aids in creating the charge, driven by the waste water, while also cleaning the waste water. This also reduces the need for a large number of membranes.
