Buckminster Fuller was a bit of a utopian, and his inventions had a bit of utopian flavor to them. One of his ideas was for an underwater city, anchored to the sea floor. It would be built around a shaft in which was encased drilling equipment for offshore oil drilling. The shaft would extend to the surface, and contain elevators for access to the surface, and pipelines for transfer materials to and from ships at the underwater city's above surface dock. Part of the design was the arrangement of anchor cables, arranged tangentially, like the spokes of bicycle wheel.
The structure also had an underwater dock, where submarines could dock to refuel or take on oil, or disembark passengers.
Fuller also designed a floating city callted Triton that would be anchored anyplace, and would hold 100,000 people. It was never built, but the artificial island of Kansai near Osako, Japan, is derived from Fuller city plans. 
The U.S. Government issued a Buckminster Fuller stamp on July 12 2004. 
how could i get more information about underwater building technology,
thanks
