Hoping to eliminate some of the multi-million tons of plastic in our oceans, the Danish company RanMarine Technology has developed an aquadrone that sucks up garbage from the water. It’s called the WasteShark, and it can “eat” up to 200 liters of trash in one trip.
The WasteShark is modeled after the whale shark, the largest fish in the world. It’s a “filter feeder,” meaning it gobbles up plankton and small crustaceans without moving much at all — prey is simply sucked into its long, flat mouth. The WasteShark operates just like this ocean predator.
“It’s built on the same principles as a whale shark,” Richard Hardiman, the CEO of RanMarine Technology, explained in a TED Talk. “It’s got an enormous mouth. It silently skims the water and tracks down its prey, keeps it in its belly.”
