Floating spheres that house entire cities and sink to the seabed in extreme weather could be built by 2030
On Earth we've colonised deserts, forests, mountains and many other locations, but we're yet to truly live on our planet's most abundant locale, namely oceans, which cover 71 per cent of the surface.That could all be set to change though as one company has unveiled designs for floating cities that could operate both on the surface and underwater. Using a number of advanced technologies, the enormous spheres could house 5,000 people and also perform research on the seabed.The futuristic concepts were drawn up by the Shimizu Corporation in Tokyo, in partnership with Tokyo University and the Japan Agency for Marine-Earth Science and Technology Each vast globe would float at the surface of the sea, but could be submerged in bad weather, down the centre of a gigantic spiral structure that plunges to depths of up 2.5 miles The spiral would form a path nine miles to a building on the ocean floor, which could serve as a resource development factory that could collect rare metals and rare earths.
