Fly-powered digital clock lasts days a diet of flies

Carnivorous plants such as the Venus Flytrap use insects to provide them with food when the environment around them doesn't provide enough nutrients. Here we have a digital clock that uses insects to provide it energy to work.

The clock requires 8 insects worth of energy to power it for about 8 days. James Auger and Jimmy Loizeau created the so-called "fly paper clock."

The white belt is flypaper, rotating around two rollers. When flies get stuck to the flypaper, the paper rotates, and eventually comes around to a blade, which scrapes them off into a fuel cell that powers a motor which moves the rollers, as well as the clock.

The fuel cell is apparently a microbial fuel cell, in which bacteria digest the flies, with the fuel cell "stealing" some of the electrons inside of the bacteria.
