How does this let fish past? Dolphins and whales use bubble corrals as a fishing technique specifically because fish don't like crossing it. I believe it's also being tested as an alternative to shark nets. Presumably this would be a more intense bubble wall, which I would expect to seriously impede the free movement of marine species.
Maybe if it were suspended near the surface of the river so fish could swim under it. That probably wouldn't let much plastic through, as this would only really be effective on floating plastics anyway.

- eloff 6y agoYeah, that's clever, it might work.

Edit: also what if most of the trash is during storm events - the system wouldn’t work if that were the case.
