Any news from him on how he's doing? It's disappointing what the Thai government did to him.
Hopefully the same thing don't happen to the project in Polynesia. That is a far ambitious project. If the government end up seizing it I'd be pissed.
This is why I would rather do it by boat. What's it going to take to drag that thing far enough away from Thailand so it won't bother them or anyone? Also, I thought there were reports from the Seasteading Institute that Elwar had gotten permission from Thailand.

A yacht - or a cruise ship. I remember watching a documentary about a family living in a yacht, a couple and a son and daughter. I think that setup is much easier to move around.
Maybe Elwar and his people lived on boats for a while. I think he wants to make something more permanent.
I think he thought he had checked into the Thai government thing before he did it where he did it. Perhaps Thailand area waters are the best suited for Elwar's project. Elevations of the oceans can be found here -

Many foreign (to the USA) countries formally agree with the 12-mile internationally accepted territorial waters limit, but in reality support a 200-mile limit which was common in the past.
