Poseidon Undersea Resorts' website now has a nice flash ad intro and a lot of content. This US Submarines-led project is supposedly under construction in Fiji, although of course one never knows with this sort of project - such things are announced and take reservations far more often than they actually open. With a planned price of $30K/couple/week it is evidence for our belief that underwater is too expensive to be a good route to seasteading.

Laissez-Faire city was a new country attempt in the 1990s, based in Costa Rica. Despite many flaws in the idea (some of which I document in my 2001 visit to CR), I will always have a warm spot in my heart for it, as it was the first project I had some firsthand experience with. Here is the ad they took out in The Economist in June of 1995:

Give it a listen. It's awesome! The ad will air on Free Talk Live. Normally we don't pay for advertising, but the rates were cheap and it's a pretty targeted show, so we figured we'd give it a try.

AMW sends us this video making it clear that cities on the sea are possible - they are being built every day. Like Royal Caribbean's new ship - the biggest cruise ship ever:

Solid_Choke posted this ad in the forums, it's great! Almost like they are thinking along seasteading-type lines.
