This prototype clock from UK designers James Auger and Jimmy Loizeau is powered by a microbial fuel cell. It features a conveyor belt of flypaper that attracts flies and drops their bodies into the fuel cell. Depending on the available fly supply, the process can generate enough power to sustain itself and power a digital clock, as well. [via Boing Boing]

    Some things immediately bring to mind that picture of two hands drawing each other. Self powered bug zapper plus a clock for the win :)

  2. Maybe this is a bad feature to include on robots with advanced AI….did anyone see The Matrix?

    That must have been a tough project to debug.

  4. I want a fly fuel cell for my iphone!

      It’s more likely that your iPhone would power itself by piercing your skin and drinking your blood while you hold it.

    The Matrix: Now a cautionary tale.

    Would be perfect if they find a way to attract mosquitoes as well.
