This solar-powered fellow is part of a robot group called Seaswarm. He and his buddies are cheap, autonomous, and communicate via GPS and Wi-Fi. And 5000 of them could theoretically clean up the Gulf oil spill in a month.
The clever MIT folks currently only have a prototype of this robot swarm ready, but it sounds amazing:
Seaswarm, as they call it, basically works like a maxi pad. 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," to quote Assaf Biderman, associate director of MIT's Senseable City Lab. The robot's entirely autonomous; it swims along, powered by a pair of solar panels. [...]Unlike traditional skimmers, which are moored to larger vessels and have to return to shore frequently for tune-ups, Seaswarms can work 24/7 for weeks on end.
Eureka is our week-long meditation on the wonders of invention, inventors and genius.
