No one is going to put $100's of millions into those cgi pics when you have nothing at all in the way of any seastead now. You don't have a population to live on any seastead, no one has bought tickets, no one is waiting in line at the dock, there's no supply lines to any seastead, no seastead approving agency, no classification category.
Your cgi highly resembles the Kulluk, and while i know Marinea is to be grounded, you may want to read up on that design's sea-keeping behavior in heavy seas. (Note in one storm with 30ft waves, the 70ft tall sides of the Kulluk were being washed over.) The Kulluk's thrusters were cut out in 2012 and auctioned off in 2013, i expect the rest of the ship was scheduled for cutting up in mid-late 2014. Now would be a fine time to ask for the stripped hull, to be converted into Marinea, if you still want to, if any of it still exists.
