Plastic eating underwater drone…
A new underwater drone concept could seek and destroy one of the ocean’s most insidious enemies, while earning a profit for plastics recyclers. This marine drone can siphon plastic garbage, swallowing bits of trash in a gaping maw rivaling that of a whale shark.
Industrial design student Elie Ahovi, who previously brought us the Orbit clothes washer concept, now presents the Marine Drone, an autonomous electric vehicle that tows a plastic-trapping net. The net is surrounded by a circular buoy to balance the weight of the garbage it collects. It discourages fish and other creatures from entering its jaws via an annoying sonic transmitter, and it communicates with other drones and with its base station using sonar.
