Auger-Loizeau's brilliant project Afterlife: There's life after death, in a battery. Speculative design at its best!

13.7 billion years before the Earth existed, the blue print and elemental makeup for this planet and all its contents were formed. The big bang is widely accepted as the event responsible for the creation of everything - The universe, its stars, it’s planets; it’s trees, animals, silicon, I-pods and humanity. Nothing, including the human body, exists that cannot be created from these basic building blocks. Under normal circumstances after death, the human body would be assimilated back into this natural system.

The Afterlife device intervenes during this process to harness the chemical potential and convert it into usable electrical energy via a microbial fuel cell - a device that uses an electrochemical reaction to generate electricity from organic matter. This electricity is contained within a familiar dry cell battery.
