GARBAGE DRONE COULD CLEAN UP OCEANS

From solar-powered underwater research bots to ones that tweet about California water quality, robots are becoming water-friendly devices. The Marine Drone is the latest among these, designed to search and destroy garbage in the ocean.

The project was spearheaded by Elie Ahovi, an industrial design student at French International School of Design. After seeing the huge amounts of junk floating in areas like the Great Pacific Garbage Patches, Ahovi and some fellow students decided to create a solution. The Marine Drone works autonomously to suck garbage into a built-in net. When the net is full, the drone is programmed to head back to its docking station and be cleaned out by a crew. Water-proof batteries power the silent electric motor, and a sonic emitter produces a signals designed to keep fish and other animals away from the net. It's unclear how effective this would be and whether it will create one form of pollution (noise) in order to clean up the plastic kind.
