The newest project out of MIT: Seaswarm robots that are designed to act like a "legion of seagoing Roombas" that skim the ocean surface to pick up oil.
The robots are each outfitted with a GPS and Wi-Fi capability to track location and communicate within a swarm. Trailing a thin, hydrophobic material that can soak up twenty times its weight in oil, the robots would have been able to clean up the Gulf of Mexico's oil spill in a mere month using a swarm of 5,000.
The way the MIT Seaswarm robots work is by finding a spill, and slowly working their way from the edges to the center. They are also reusable, making them an eco-friendly choice for a serious problem.
