Japanese engineers envision a city underwater....[font=ars-maquette-web, sans-serif]As rising sea levels pose an increasing threat to island dwellers, a Japanese civil engineering company has come up with an ambitious solution: an underwater city.[/font]The proposed Ocean Spiral would consist of a large sphere just below the surface and about 546 yards in diameter, occupied by homes, businesses, and hotels.
Under that, a spiraling structure leading down to the sea floor would provide a way for scientists to extract resources for energy.
In a statement to The Guardian, Shimizu Corp spokesman Hideo Imamura said, "This is a real goal, not a pipe dream." http://www.ign.com/articles/2015/01/20/japanese-engineering-firm-wants-to-build-an-underwater-city
