Japanese built the world's first underwater city in just some ...

People settled in deserts, forests, mountains and many other places in the world, completely forgetting about the seas and oceans, which cover 71 percent of the surface of our planet. "Disorder" - thought the Japanese company Shimizu Corporation and has designed floating cities to live in the deep ocean.





According to the newspaper Daily Mail, a high-tech city in the form of huge balls with a diameter of 500 meters and a capacity of 5,000 people each can float on the surface or under water. In developing the concept attended the University of Tokyo - the most prestigious university in Japan - and the Japan Science and Technology Agency to study the subsoil (Jamstec).





Each ball can be submerged by a huge spiral structure, dating back to a depth of 15 km, which can be a plant for the extraction of minerals. Residential system of huge balls is considered by the company as a safe shelter for people during the earthquake and tsunami, quite common in Japan.





It is planned that the oxygen is converted to carbon dioxide, and a large difference in temperature and pressure used to produce electricity. The cost of the spiral structure is estimated at about $ 25 billion. The first such complex could be built by 2030.





The construction is planned to involve industrial 3D-printers, as well as the main construction material used rubber. According to Shimizu, the development of the concept of a floating city took two years.
