Many small countries are in real need of additional sovereign territory. Sometimes, they even build on rotting landfills and install various kinds of expensive artificial islands. The ocean covers 71% of our Earth's surface. Those countries (or persons of wealth) starting the early colonization of the ocean may obtain advantages through additional territory or creating their own independent state. An old idea is building a big ship. The best solution to this problem, however, is the provision of floating cities, islands, and states. The authors propose to employ floating cities, islands, and states as cheap floating platforms created from a natural ice field taken from the Arctic or Antarctic oceans. These platforms protected by air-film (bottom and sides) and a conventional insulating cover (top) and having a cooling system can exist for an almost unlimited period of time. They can be multiplied in number or increased size at any time, float even in warm-water subdivisions of the world-ocean, travel to different countries on continents and islands, serve as artificial airports, harbors and other marine improvements, as well as floating cities and industrial bases for virtually any use.
