Fuel Cells Powered by Creepy Crawlies?

Imagine if the bug zapper at the family barbeque was actually generating power for the house. Instead of the lights dimming every time a big one gets the zap, maybe there could be a power surge. A scientist and four of his students at Feati University in Manila claim to have created biological fuel cells that use household pests like cockroaches, mosquitoes, flies, and rats as their energy source. An enzyme found on bacteria such as E-coli, which is in turn found on common household pests, functions as the catalyst. Apparently cockroaches put out the most juice. Go figure. :: Manila Times
