Is Japan building an underwater city?

A Japanese construction company has proposed an eco-friendly underwater city, which could house 5,000 inhabitants and generate its energy from the seabed. Called Ocean Spiral, it’s the brainchild of the country’s innovative Shimizu Corporation.

Can underwater cities exist?

Pavlopetri is thought to be the oldest underwater city in history. Located on the southern coast of Lakonia in Greece, the flooding of the city is said to have taken place around 5,000 years ago. It’s been an archaeological site of great value since it was discovered in 1967.

Can underwater cities work?

In theory, underwater cities could help relieve pressure for more power, food, and water on land, while providing a new place to store carbon dioxide. The city could automatically generate all of the energy it needs, using the temperature difference between surface water and the deep sea to make thermal power.

How much would an underwater city cost?

For energy, the 5,000 undersea dwellers could generate thermal power using the difference between surface water and deep-sea temperature. According to Shimizu Corporation, building the Ocean Spiral City could cost up to $26 Billion.

Why don’t we build cities underwater?

First and foremost, it appears that humans should not build colonies deeper than 1,000 feet (300 meters), and ideally at much shallower depths. This is because the pressure at these depths would not only require very thick walls but would also require lengthy periods of decompression when returning to the surface.

Can humans adapt to living underwater?

Evidence that humans can genetically adapt to diving has been identified for the first time in a new study. The evidence suggests that the Bajau, a people group indigenous to parts of Indonesia, have genetically enlarged spleens which enable them to free dive to depths of up to 70m.

How long can humans live underwater?

The record is 24 minutes and 3 seconds. Most people can’t go more than a minute or two. What if people could grow gills? They could live underwater like mermaids!

Why don’t we colonize the ocean?

The main reason we haven’t colonized oceans yet is the fact people feel too comfortable on the steady ground. Most of us don’t want to leave their familiar way of life. We are not motivated. Sooner or later, humanity will have to find another inhabitant.
