Fly-Eating Clock
This clock, designed by James Auger and Jimmy Loizeau, obtains its own energy source. A conveyor belt of fly Paper attracts and catches house flies which are then dropped into a microbial fuel cell. In the cell, bacteria munch away at the dead flies and the chemical energy produced is converted into electrical energy, powering the clock.
Insect-eating robots have also been developed. A robot which feeds itself is essentially self-sustaining.
