Waste water 'can provide power'

Breakthrough that combines fuel cell with other technologies could provide power for entire water grids, scientists saySewage 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."His team's work is published in the journal Science and is "the proof of concept", Logan said. "Our hope now is to optimise the electricity generation as much as possible."Switching sewage plants from users to generators of electricity would be especially useful in developing countries, said Logan, an environmental engineer specialising in water systems.
