The video explains a system that simultaneously desalinate water and generates electricity. Giant buoys tethered to hydraulic pumps on the ocean floor harness kinetic energy from ocean waves. This energy is used to spin turbines for electricity and push seawater through a reverse osmosis membrane, resulting in zero emissions drinking water.
