 This Scientific American 60 Second Science, I'm Sophie Bushwick, got a minute.Developed countries spend about 3 percent of all their electrical power treating waste water, the juice purified contaminated material so it can be returned safely to the environment , now researchers think they can turn these power drain into a power source, because the new kind of battery uses microbe to produce electricity from waste water, the work is in preceding of national academy of sciences, like us some microbes draw their energy from organic matter and waste water is chock full of such fuel, so scientists give microorganisms polluted water and wired them up, when the microbes have send electrons the particles travel through the electronic components 1 to power a battery, this system had a net efficiency of 30 percent about the same as the commercial solar cell. In theory, microbe batteries like this one could eventually be made more efficient producing enough electricity to power the treatment waste water three times over which give a whole new meaning to the saying waste not want not.  Thanks for the minute, for Scientific Americans 60 Second Science, I'm Sophie Bushwick.
