Joe Quirk is the president of the Seasteading Institute, which hopes to see the world’s oceans settled with hundreds of environmentally restorative floating cities. The first steps in that process are currently underway. “We’re going to start very small with sustainable floating islands in the protected lagoon of Tahiti, for about 250 people,” Quirk says in Episode 289 of the Geek’s Guide to the Galaxy podcast. “We hope to have this available by 2020.”
