"Plastic pollution threatens marine life, humans and ecosystems. Enter FRED, a future vacuum of the seas."
"SAN DIEGO — A spring storm had retreated inland during the night, leaving a canopy of unbroken clouds over Mission Bay. About 20 engineering students and others gathered in the morning chill to launch a cockeyed-looking vessel, mechanical guts fully visible, into the still water.
The contraption’s hull, cannibalized from a 16-foot, decades-old catamaran, supported a conveyor belt, motor and array of batteries the size of a picnic cooler. Solar panels were mounted like an awning atop the aluminum frame. Its creators had relied on off-the-shelf materials during construction and christened the result FRED — an endearing acronym for floating robot for eliminating debris.
“We’re just happy that it floats,” joked Justin Ho, a mechanical engineering major at the University of California at San Diego, who took the first turn at remotely steering the prototype around the bay using a modified video-game controller."
