Japan’s Ocean Spiral proposed as giant underwater city

Story highlights

Ocean Spiral is a proposed underwater city from Japanese construction firm Shimizu Corp.

The futuristic settlement has been designed to produce all its own energy and will have enough room to house 5,000 people

Project expertise is being sought from academics, Japanese government departments and energy experts, the company says

CNN  — 

What would happen if the legend of the Lost City of Atlantis was crossed with the screenplay of Kevin Costner’s 1995 hit movie “Waterworld”?

Maybe something like The Ocean Spiral – an underwater metropolis that generates energy from the seabed and is capable of providing homes and accommodation for 5,000 people.

Sure, such blue-sky thinking may only seem plausible in the world of Hollywood CGI, but this is the futuristic concept proposed by Japanese construction firm Shimizu Corp.

According to literature released by the company, expertise is being sought from Tokyo University, Japanese government ministries as well as energy firms to bring the project to life.

Shimizu also say projects like the Ocean Spiral may be necessary in the future to confront increasing global problems such as rising sea levels and the need to create new, clean energy sources.

Under the sea

Divided into three distinctive zones, the structure will stretch all the way to the crushing black depths 2.8 miles under the sea off the coast of Japan.
