This is the Jelly-fish 45 underwater habitat. It can house up to 6 people on 4 levels. The top three levels are above sea level, while the bottom level is semi-submerged. You are supposed to chain these things up in a bay or a marine park - but I'd like to see someone live in one out at sea. I'm sure this wasn't designed to handle that, so they might need to toughen the habitat up a bit. And, I guess you'd end up starving to death or something if you were just afloat upon the waves indefinitely. So, you'd probably want to equip it with some sort of propulsion system. And a garden. And a way to get drinkable water. Then it would be awesome. Buy one
here for only $2.5 million. There are a couple other cool habitats there as well, and a bunch of submersibles. [HT:
