Sean Ironstag’s quixotic quest to build a society of plastic floating cities to clean up the ocean
Five years ago, Sean Ironstag got on a friend’s yacht without knowing where they were going or how long they’d be gone. “It turned out we went straight out into the middle of the ocean,” he remembers. About a week later, they dropped anchor and went for a swim. “And when I came out,” he says, “it looked like my body was covered in glitter.”
and
The “glitter” on his body was tiny pieces of floating plastic, broken down by sunlight in a process called photodegradation. The resulting fragments, small but persistent, are nearly impossible to clean up. As scientists have learned, these small pieces, some of them microscopic, crowd out the natural sea life near the ocean’s surface: There are swaths of the Pacific Gyre where the ratio of plastics to plankton is on the order of 100:1. That’s thrown the whole ecosystem out of whack. How that affects humans is the subject of ongoing research, but it is clear that these microplastics are sponges for pollutants and that they’ve entered the food chain. They get eaten by zooplankton, which mistake them for phytoplankton. The zooplankton get eaten by fish, which get eaten by larger fish, which get eaten by humans...
and
Still, Ironstag learned a lot along the way. Finally, he says, “It all just fell into place and just clicked.” He devised a radical plan: floating platforms that would pull plastic from the ocean, then recycle it into building materials to further expand these cities on the sea. Or, as he puts it, “The solution to one of humanity’s greatest problems right now is harvesting that plastic and recycling that plastic on-site, then running it through mobile 3D printers to create these hexagonal modular platforms that connect together using electromagnetic technology and are powered by waveplate generators beneath them, and then building on top of those."
Helluva concept.
