Ocean Spiral: Nature Friendly Underwater City Producing Its Own Energy

Ocean Spiral: the conceptual underwater city, developed by the Japanese engineering firm Shimizu Corporation, envisages a habitable settlement at the surface level, will use the ocean resources for fully self-sufficiency.

The underwater city, is still at the design stage, will produce its own renewable energy and be environmentally friendly. The extraordinary design, that we are accustomed to seeing in utopic movies, can accommodate 5000 people.

The city will have water treatment system for drinking water and also have large underwater farms where fish, crustaceans and aquatic plants could be cultivated. And perhaps most importantly, Ocean Spiral could transform carbon dioxide into methane through using microorganisms living in the sea bottom in order to produce its own energy.

Shimizu Corporation first unveiled the concept of Ocean Spiral in 2014, together with Tokyo University and the Japan Agency for Marine-Earth Science and Technology. It is claimed that the underwater city, will cost about 20 billion pounds and be ready for settlement by 2030.
