Seaswarm is a new oil-skimming system that can autonomously navigate the water’s surface. Seaswarm units are self organizing and can clean an oil spill more effectively than current methods. Seaswarm uses a photovoltaic (solar) powered conveyor belt made of a thin nanowire mesh to propel itself and simultaneously collect oil. This nanomaterial, patented at MIT, can absorb up to 20 times its weight in oil. As the flexible conveyor belt softly rolls over the ocean’s surface, it propels the unit forward, absorbing oil as it goes.
