Rather like the vermin accessories, here’s another strange meeting of design and dead animals. This time it’s furniture – furniture that draws power out of dead insects or animals. The devices capture insects or mice and deposit them in a fuel cell that uses bacteria and enzymes to generate electricity from their corpses. All of these machines are very simple, but there is mention of a robot that can be powered by dead flies.
In a sci-fi setting this would add a macabre edge to things. After all, by harvesting electricity out of human brains, the machines in The Matrix were essentially treating people as a fuel cell, why not just go the extra mile?
Alternatively, in a fantasy setting there may be machines that are artifacts of some ancient culture. Devices that now require sacrifices to generate their power – something like Blackrazor only it devours flesh rather than souls.
