developed country spend about 3% of all their electric power treating waste water.the juice purified contaminated material so it can be returned safely to the environment.

now ,researchers think they can turn this power drain into a power source ,because new kind of battery uses microbes to produce electricity from waste water。work is in the proceedings of national academy sciences。like us,some microbes drain their energy from organic matter and waste water is chock full of suck fuel。

so scientists give microbes organise polluted water and wire them up.when the microbes have send electrons ,the particles travel through the electrinic components to power a battery.this system had a net efficiency of 30%, about the same is commercial solar cell.in theory microbe-battery like this one could eventually be made more efficient.producing enough electricity to power the treatment of the waste water 3 times over.

which gives a whole new meaning to the saying , waste not want not.
