The Ocean Spiral, an underwater city that can generate energy from the seabed and is capable of providing lodging for 5,000 people may soon become a reality, it has been reported.
For the futuristic concept was proposed by Japanese construction firm Shimizu Corp, and the expertise was being sought from Tokyo University, Japanese government ministries as well as energy firms to bring the project to life, CNN reported.
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.
A giant sphere with a diameter 500 meters (1,640 feet) situated just below the surface will form the first section and house residential zones, businesses and hotels.
This inhabited area would be connected to a nine-mile spiral (section 2) that descends to the seabed where a deep-sea submarine port and factory (section 3) would create the energy required to power the sphere by using micro-organisms that turn carbon dioxide into methane.
The company stated the Ocean Spiral would take five years to build and the technology required will be ready in 15 years.
