This LED clock from British designers Jimmy Loizeau and James Auger. Part flycatcher, part timepiece, the gizmo harvests insects on a sticky roller covered in flypaper, before dropping the corpses into a microbial fuel cell.

The dead bug is then digested by the bacteria within, and the chemical changes are used by the cell to power the clock. Simple, huh?


The insects become trapped on the flypaper stretched over its roller mechanism.



At the base of the roller, a scraper removes any captured insects.
They fall into the microbial fuel cell beneath, where bacteria digest the fly and cause chemical changes that the cell can extract power from.
The energy is used to power the LCD clock and keep the roller revolving.
