Clock powered by dead flies


[video link]

This prototype clock, designed by James Auger and Jimmy Loizeau, is powered by dead flies. A conveyor of fly paper catches the insects and then drops them into a microbial fuel cell where they become feedstock for bacteria to consume. As the bacteria munch on the dead flies (or most any organic matter), the chemical energy is converted to electrical energy. The same technology powers the sewage-eating robot I posted about last year and also appears in the video above. (via Daily Grail)
