can. When the methane is biochemically converted into carbon dioxide, the archaea that occur in lakes and ditches release electrons that can be dissipated as electricity. In initial tests, the efficiency of this biochemical power generation was only 17 percent, but it could be increased, according to the team. The “methane eater” microbe could thus open up new possibilities for generating electricity from biogas...
