Bacteria Powered Batteries

Posted by Hemos on from the it's-elementary-chemistry-my-dear-watson dept.

Agent Provocateur writes "SpaceDaily reports on a battery that is powered by chemical reactions caused by bacteria. A Pentagon-backed project, University of Massachusetts researchers Swades Chaudhuri, an Indian, and Derek Lovley, an American, say the battery's source is an underground bacterium that gobbles up sugar and converts its energy into electricity. Their prototype device ran flawlessly without refuelling for up to 25 days and is cheap and stable." The chemistry behind this thing isn't really that complex - keeping the bacteria alive and kicking during that time is prolly the tougher part - you can read more on Al Jazeera, and USA Today. Now, what about replacing this battery?
