New Device Harnesses Sun and Sewage to Produce Hydrogen Fuel

At the University of California, a new discovery of an invention was made. This device uses microbial fuel cells, solar cells called photoelectrochemical cells. The microbial fuel, the bacteria in it takes the organic materials from water, and possibly creates electricity. The electricity that is produced is used with the photoelectrochemical cells and can split water. The outcome of this is hydrogen and oxygen are produced in the process of hydrolysis.
