Whale sharks are great at filtering; plastic needs to be filtered. For now, however, whale sharks only have an appetite for plankton. Industrial designer Elie Ahovi has jumped into the void with her Marine Drone, an autonomous robot that can dredge up the plastic junk that currently clogs our oceans. Roaming the ocean for two-week periods, Ahovi’s drone can collect plastic in its attached net while scaring off any marine life with an irritating high-pitched tone. When its batteries run low, the robot returns to a home base where humans can collect the plastic and ship it off to a recycling plant.
