An aquatic vacuum cleaner

The WasteShark is a 1.5 metre long drone that works like an aquatic vacuum cleaner. It’s modelled on the whale shark, which is a filter feeder that sucks prey like plankton into its mouth. As it ‘swims’ through water, the WasteShark sucks in plastics and other rubbish, eating up to 200 litres of waste in a single trip. The drone is capable of swimming for up to 16 hours and can be controlled manually or set to patrol a defined area.
