As more and more coastal cities face growing challenges ranging from rising sea levels to population density problems, more and more urban planners are switching to building unconventional means as a solution. A Japanese company recently flashed in headlines for coming up with a very novel proposal – building underwater cities – cities of the future!

A futuristic concept for a self-sufficient city, The Ocean Spiral, has been designed to float amidst the eeriness of the sea and uses the ocean to run infrastructure that could support 5000 citizens.

Japanese Firm Comes With First Underwater City

A goliath sphere, 500 meters in width, would hold a tower with many lofts and bigger homes, stores, work places, an inn, and research zones, all sliding 75 stories down into the water. A seawall would circle the giant sphere, keeping vast waves away, while tethers and ballasts keep the city from floating in the water.

Despite the fact that building underwater structures means several challenges, the company behind the novel concept accepts that it likewise could have different points of interest, environmentally for the planet.

Hideo Imamura, a spokesperson for Shimizu Corporation, the Japanese company behind the concept, the deep sea contains colossal potential possibilities that can probably help humans with the current devastating environmental problems. The underwater cities could help soothe pressure for more power, sustenance, and water on land, while giving a new place to store carbon dioxide.

The city could produce greater energy, utilizing the temperature contrast between surface water and the deep sea to generate thermal power. A long spiraling tube would make a trip nine miles down to the ocean depths, pulling frosty water up for the city’s energy plant.

Build World’s First Underwater City

Utilizing a part of the same energy, the city would likewise run a desalination system to give unlimited freshwater to the citizens. As agriculture on land faces challenges to feed a growing population on the planet, the underwater city would reply on aquaculture farm, basically a huge, partically encased aquarium for raising fish—close to the base of the circle.

To help address global climate change problem, the city would send carbon contamination from power plants and other area based sources down to the ocean depths, where microorganisms would convert into methane gas. The company additionally wants to harvest new resources from the ocean depths, instead of mining. New systems may mirror common techniques to start growing and reaping new minerals.

The company believes that all of this is attainable, and has been chipping away at the subtle elements with experts from Japanese universities and national agencies. One of the greatest obstacles, the company says, will be making sense of how to assemble the city, the development of the concrete sphere will happen in the water, utilizing a tremendous 3-D printer. The project is estimated to cost around $26 billion.
