Giant Plastic Trap Breaks, Gets Towed Back To Land (npr.org) 142

The "Ocean Cleanup" project deployed a 2,000-foot floating debris trap in September near a drifting plastic patch in the Pacific Ocean that's twice as big as Texas. It broke.

An anonymous reader quotes NPR: Invented by Boyan Slat when he was just 17, the barrier has so far done some of what it was designed to accomplish. It travels with wind and wave propulsion, like a U-shaped Pac-Man hungry for plastic. It orients itself in the wind and it catches and concentrates plastic, sort of. But as Slat, now 24, recently discovered with the beta tester for his design, plastic occasionally drifts out of its U-shaped funnel. The other issue with the beta tester, called System 001, is that last week, a 60-feet-long end section broke off.

The first issue, Slat said, was likely due to the device's speed. In a September interview with NPR, he said the device averages about four inches per second, which his team has now concluded is too slow. The break in the barrier was due to an issue with the material used to build it. "In principle, I think we are relatively close to getting it working," Slat said in an interview Saturday with NPR's Michel Martin. "It's just that sometimes the plastic is also escaping again. Likely what we have to do is we have to speed up the system so that it constantly moves faster than the plastic." For the material failure, Slat said his team will probably try to locally reinforce the system to combat the problem of material fatigue.

Slat's U-shaped plastic trap is now being towed the 800 miles back to Hawaii for repairs.

  • Enough said - it's nice that someone is trying to do something, and I'm sure the guy is good-intentioned - but pretty much all the experts said this would happen and the resources would be better spent elsewhere.

      Prototypes rarely works perfect the first time. Build it stronger, try again. Normal for untested novel devices.

      Also, it doesn't matter if the thing occationally looses a piece of plastic - as long as it catches more than it leaks.

      I, and probably you too, came up with much greater things when we were young.
      And we could also have actually created them.
      But I don't remember us having millions to pay engineers and entire damn towing ships and so on.

      • We imagined 'greater things', now we can actually build real things.

        I've known some smart kids, but never one that had an intuitive understanding of cast/benefit. You have to earn that with past mistakes. Get over loving your own ideas. 'Everything is a tradeoff' is drummed into your head in engineering school, as it should be.

        Bet this boom has shed more weight of plastic than it collected, as will the next prototype.

      At least he's trying. I see nobody else try something like what he does.

        There is a reason for that: There are 150,000,000 tons of plastic in the oceans now, and 8,000,000 tons new each year. Each trap was supposed to clean up 150,000 POUNDS of plastic each year (if it worked 100%). You would need 2 million of these to clean up what is in the oceans now, and another 100,000 just to get the new waste. This is why no one is trying anything like what he is doing. It is a stupid idea.

    Almost all the plastic trash going into the sea is coming from a handful of rivers in Asia & Africa. So why not put this plastic trap at the river mouths of those high trash rivers, like the Ganges or Yangtze? Seems to me like it would be easier to catch the plastic in such concentrated locations, before UV rays & ocean waves have broken it down into little bits.
    • by Anonymous Coward on Sunday January 06, 2019 @09:21AM (#57913018)

      That would require Indians and Asians to actually give a fuck, which clearly they don't.

      It's why climate change is inevitable. Any solution which requires cooperation from India and Asian countries is doomed to fail and is simply a waste of effort and money.

        FTFY.

        There are also a lot of other entities that could be substituted there. You could probably boil it down to just "any solution which requires cooperation".

        Um, most of the plastic there comes from the West who are simply exporting the problem, and some of them do give a fuck, which is precisely why China has now refused to accept any more plastic waste exported to it from the West.

        And the US is STILL by far the biggest polluter on the planet, whatever lame efforts it's made so far to change that, so suggesting the problem extends to India and Asian countries too is utter nonsense.

        It's pretty clear the West at very least deserves equal blame for the problem.

        • Most of the plastic is simply domestically generated in China and India. And even if plastic is imported, it becomes their responsibility.

    • Almost all the plastic trash going into the sea is coming from a handful of rivers in Asia & Africa. So why not put this plastic trap at the river mouths of those high trash rivers, like the Ganges or Yangtze?

      As you can see just by the posts in here, a lot of people simply want to blame the USA.

      Weird, when the problem is completely visible and undeniable to people who are rational, and can look at pictures and video and see the sources.

      Rational people also understand that you don't fix problems by attacking the wrong country, something we painfully learned a few years back.

          You're gonna have to explain that. I can't fit it into the context of what we are talking about.

          Explain how reducing the US's plastic oceanic pollution is going to eliminate plastic in the ocean. If the USA didn't exist, would it have to be invented so you had something to blame it on?

          I understand that I'm an idiot, but in most cases, a problem can be fixed by treating the source of the problem. Me? My way of approaching the problem is to stop it at the source. We ain't the source.

            Gladly. Shithole nations are followers in every way. We brought them technology, products, processes, and money by the bucketload. The Vietnamese who are pouring mountains of plastic into the ocean didn't invent these, they were introduced to them by western nations.

            As such pointing the finger to their waste without demonstrating a suitable alternative is disingenuous. They learnt to drink from plastic bottles from us, it's up to us to demonstrate that they can live without it too.

              Fascinating rationale. Problem is, the alternative to just plopping the plastics into a river that ends up in the ocean has been around a while: https://en.wikipedia.org/wiki/... [wikipedia.org] . Especially that in some of these countries, labor is in ready supply, and one of the issues - that of sorting - can be largely taken care of.

              They learnt to drink from plastic bottles from us, it's up to us to demonstrate that they can live without it too.

              I doubt that living without plastic is practical. Recycling is practical.

              Despite my flippant comment the USA still is the most powerful nation in the world. Do not underestimate the amount of influence it has on waste from these countries. And despite my comment I don't call out USA alone here. All western nations have a role to play, not the least those such as Australia who actively exported their plastic waste to they very countries which are accused of polluting the oceans with it.

              We should once again become the leaders we have always claimed to be.

              There seems to be an undercurrent that China buys this plastic, then dumps it. Strange business model, that. What they did do, was process plastic and paper. Did do, because they stopped https://www.nytimes.com/2018/0... [nytimes.com]

              Now, between you and me and the voices in our heads, there is precious little that the US can do by itself. Or Europe. We can stop sending our recyclables to China, and do our own recycling, that's been taken care of

            • Hold on a moment, are you saying that because the US introduced someone to an invention, we're responsible for it's misuse all the way down the line? If that's the case, then China is responsible for all gun violence.

      A handful seems misleading based on this [theoceancleanup.com], there are also no small few in North America and Europe. I also wonder if we were to consider population whether it would look similar.
    • Do you have any proof this is the case?

      • He read a headline and not an article. Only about 20% of world plastic waste comes from rivers. However that 90% figure is still right with a caveat: 90% of plastic waste coming *from rivers* comes from just 10 rivers in the world.

        Every article I've seen on this topic has the headline misrepresent this fact but gets it right in the article itself: https://www.weforum.org/agenda... [weforum.org]

    • Almost all the plastic trash going into the sea is coming from a handful of rivers in Asia & Africa.

      Oh look this again. No no it doesn't. Stop reading just the headline and read TFA where you originally heard this fact. Only about 1/5th of the plastic in the ocean comes from Rivers. The 90% number is the amount of plastic that goes to the sea FROM RIVERS comes from just a handful of rivers, 8 in Asia, 2 in Africa.

      To be clear 90% of 20% total is still a high number and it's well worth filtering those streams, but if you're going to be armed with facts at least get the facts right.

      • Only about 1/5th of the plastic in the ocean comes from Rivers

If you're at all willing to advance yourself rather than just post shit you'd google it and self educate on the topic too you'll very quickly come up with lots of articles all pointing to a study of waste from rivers which made the original claim that 90% of the waste *from rivers* comes from just 10 rivers and footnotes saying that makes up 1/5 to 1/4 of the total waste depending on which oth

    Somebody makes an invention that, in beta form, is flawed. They see a clear path to success so they go about making that happen. Then people come and crap. I remember when conversations on /. were decent, but it's been a while.

    • The entire idea is flawed and self-serving. 8 million tons of plastic enter the oceans each year. Even if this thing worked 100% you couldn't build enough of them to make an appreciable dent in the incoming waste stream.
      • Why bother to clean up litter at all? If we reduce the waste stream and clean up over years, we'll improve things. There's no reason to give up before we even start.

        • Go ahead and clean it up. Are you not understanding? It would require millions of these things to make any difference (and they would need to work). The point is we need to stop producing it. You cannot clean it up. It is too late for that.

            The nice thing about garbage dumped in the oceans, if there can be said to be any nice thing about it, is that a lot of it actually ends up in several relatively small patches. I've actually the north atlantic garbage patch. Pretty gross the way garbage builds up there. I suspect it's a node where currents create a convergence.

  • The currents determine where things go. And there's a giant trash heap sitting there. Send some barges and scoop the crap up and send them back. The currents will bring the vast majority of it to you.
