Researchers at MIT have invented a new robotic oil skimmer, called Seaswarm. Senseable City Lab is unveiling the first prototype at the Venice Architecture Biennale on Saturday. The hope's to produce a whole fleet of Seaswarms that'll be able to attack oil spills like a swarm of bees. A patented hydrophobic nanofabric devours as much as 20 times its own weight in oil without collecting water. To capture the oil, the nanofabric's draped over a conveyor belt that's then dispatched on the surface of the ocean like "a rolling carpet." The robot's entirely autonomous; it swims along, powered by a pair of solar panels.
