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.

The trash wheel is great, so much garbage used to clog the harbor after it rained, now there's barely any.
