Now is the time for us to create a new interface with the deep sea, the earth’s final frontier,” says a brochure from Japanese development company Shimizu Corporation, presenting their outlandish proposal for the Ocean Spiral: a deep sea colony that can supposedly provide for up to 5,000 people in its 500m wide tethered sphere.

The proposal describes the Ocean Spiral as “safer and more comfortable” than existing land-based cities, thanks to the near constant temperature enabled by the ocean, the fact that it will be unaffected by typhoons or earthquakes, and the hope that the city’s methods of oxygen generation will enable higher concentrations of oxygen then are found in the Earth’s atmosphere.
