this shows a centrifugal fan mounted on floats which turns in the wind to generate power below the water to turn the propeller. that propeller directs ocean water and its plastic pollutants into a trailing filter bag. when full it can be gathered by ship or directed by GPS signaling to return to land as designed. special care should be taken to insure methods for life to remove itself from the bag: such as a large ducted propeller operating at slow speeds with escape areas.
