A similar item is Baltimore's "Mr Trash Wheel" [1] which in one year has kept over 350 tons of trash from going into the harbor. It even has it's own twitter account [2].
Something like the trash wheel is most effective at choke points where a bunch of trash is getting funneled into a fairly narrow space versus the open ocean, but it's amazing how much trash it has kept out of the harbor and thereby the ocean.
