    I saw this on a few news sites today.

    Ocean Cleanup steams out to sea in test run to clean Great Pacific Garbage Patch

    Does anyone know any more about it? It sounds like a terrible idea to me, basically a deliberately launched ghost net? Maybe I'm not understanding something, but usually fish don't just "swim under" nets...they get trapped and die in nets.

    I hope I'm simply not understanding something special about it.

    Because humans can't ever fix a problem without creating a bigger one, this is probably going to turn into a disaster. A hurricane will hit and turn the clean up system into it's own pile of floating garbage or it'll become self aware and re-form itself around LA to trap the garbage there. Maybe it's not all bad.

    However, it's not a net. It's more like a giant floating pool noodle with a sheet of plastic hanging underneath it. The water doesn't flow through a net or anything that can trap fish or anything else under the surface. The water will end up flowing underneath the plastic skirt, carrying wildlife with it. Trawling nets work because the water can flow through, but the fish can't, so the constant pressure of the water keeps them in it.

    Anything floating on the surface will be trapped in the pool noodle part of it and concentrated for easier clean up.

    @kelemvor @kmarks hit it on the head. The key here is to think of this like the floating pool noodles they use to contain oil slicks. Since the plastic they're trying to contain is floating they just need something that goes a foot or two deep and is a few feet tall but can easily be solid vs. a net.
