An aquatic robot that devours plastic junk in the oceanGeorge Dvorsky7/17/12 2:40pmFiled to: This is awesomeRobotsRoboticsDronesAutonomous robotsPollutionScienceScitweetFb76EditPromoteShare to KinjaToggle Conversation toolsGo to permalink Autonomous drones typically get a bad rap, but a new design by Elie Ahovi actually looks like it could be genuinely helpful. Concerned about rising levels of plastic waste in the oceans, Ahovi put together a design for an underwater drone that can search for and gobble-up ocean garbage. It's hoped that this device, when used en masse, could dramatically reduce the plastic islands that are forming in virtually all the Earth's oceans. The drone works by patrolling the oceans autonomously, sucking plastic bottles, garbage bags, and any other kind of waste into its gaping mouth. Once full, the drone will locate and dock with its mothership, where crew members will pull the device out of the water and empty it of its contents.
