<i>Retarded about the platform. Why not use an island instead?</i><p>Actually their plans are very well thought out.  (And apparently you didn't read them before you decided to critique.)<p>Basing a platform on the principle of a Spar Buoy gives them immunity to just about any rogue wave or tidal wave nature, given enough clearance.  Their larger designs could ride those out, while most buildings on an island would be toast.<p>Also, nature's not making new sovereign islands at a particularly useful rate.
