Floating spheres that house entire cities and sink to the seabed in extreme weather could be built by 2030
Tokyo-based construction firm Shimizu Corporation has revealed concepts for futuristic cities
Called Ocean Spirals the massive structures would float on the top of oceans and submerge during bad weather
Each sphere is 1,600 feet (500 metres) across and can accommodate 5,000 people in homes and hotels
The spheres would be placed at the top of spirals 2.5 miles deep with a research station on the seabed
Shimizu says it would cost £16.2 billion ($25.5 billion) to build the first sphere, which could be done 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.
