Science -- Abstracts: Bond et al. 295 (5554): 483
Essentially, the experimenters grew a bacterial culture in a battery in the presence of organic material (mud). The bacteria used the organic material as a source of energy and carbon, and produced electrons that were then attracted to the anode. This creates a potential across the gap, storing energy in the same way a battery does (I am not an EE, so don't sue me if my description of a battery leaves something to be desired). This may pave the way to a method for practical bioremediation and bio-powered electrical production. I am sure it is a long way off, but it is cool nonetheless.
