bacteria turn gears Harnessing bacteria to turn gears

This looks neat, a team of scientists from the Argonne National Laboratory and Northwestern University have figured out how to get bacteria to spin tiny gears. Though the gears themselves are small, the bacteria are even smaller, so apparently it takes hundreds of them swimming in swarms to produce enough energy to turn the gears. Anyone have ideas about how to turn these gear motions into logic gates? I’d love to have a bacteria-powered computer! [via boingboing]
