Sewage can be used to generate electricity using a new device revealed by scientists on Thursday. It combines a fuel cell with other technologies to convert waste water treatment stations into power plants, which the researchers believe could provide the power for entire water grids. “We certainly could take care of the whole water system : the treating and pumping of water, which currently requires substantial amounts of power,” said Prof Bruce Logan at Pennsylvania State University in the US. “We also treated the organic matter much faster.” Read More
