Ocean Cleanup Device Shows It Can Remove Plastic From the Pacific:
It's been nearly a decade since Boyan Slat announced at age 18 that he had a plan to rid the world's oceans of plastic.
Slat, now 27, is a Dutch inventor and the founder of the Ocean Cleanup, a nonprofit that aims to remove 90% of floating ocean plastic by 2040.
That goal has often seemed unattainable. The Ocean Cleanup launched its first attempt at a plastic-catching device in 2018, but the prototype broke in the water. A newer model, released in 2019, did a better job of collecting plastic, but the organization estimated that it would need hundreds of those devices to clean the world's oceans.
Scientists and engineers began to question whether the group could deliver on the tens of millions of dollars it had acquired in funding.
But over the summer, the organization pinned its hopes on a new device, which it nicknamed Jenny. The installation is essentially an artificial floating coastline that catches plastic in its fold like a giant arm, then funnels the garbage into a woven funnel-shaped net. Two vessels tow it through the water at about 1.5 knots (slower than normal walking speed), and the ocean current pushes floating garbage toward the giant net.
In early August, the team launched Jenny in the Great Pacific Garbage Patch, a trash-filled vortex between Hawaii and California. The garbage patch is the largest accumulation of ocean plastic in the world, encompassing more than 1.8 trillion pieces, according to the Ocean Cleanup's estimates.
Last week, Jenny faced its final test as the organization sought to determine whether it could bring large amounts of plastic to shore without breaking or malfunctioning. The Ocean Cleanup said the device hauled 9,000 kilograms, or nearly 20,000 pounds, of trash out of the Pacific Ocean — proof that the garbage patch could eventually be cleaned up.
"Holy mother of god," Slat tweeted that afternoon, adding, "It all worked!!!"

If they were operating closer to shore then they would either be collecting even less material or their technology is better than it sounds, because any collection system will always be most effective where the garbage is densest, either directly at the mouth of a major river (where they would be seen) or at the heart of the GPGP, which can be verified by tracking the tugs' transponders. Scammers also don't like the kind of public scrutiny he's inviting. They always have some pseudo-scientific 'secret sauce' miracle technology or new-age magnetic meditation crystal. There is nothing magical or unexplained about using nets to catch garbage out of the water, only the usual engineering hurdles to mature the technology and make it cost effective.
A project like this can't really be profitable no matter what you do since most plastic isn't recyclable, and the rest is marginal at best, so he needs public support to attract donations and government grants to keep it going. Twitter is a cheap and effective way of getting and keeping that public support.

Per chance, have you stumbled across the names of the boats? I did want to check the AIS records for them, but the are notably absent from their website, twitter feed, etc. Did I just miss them?
