Japan is planning one of the world’s most ambitious infrastructure projects—Ocean Spiral, a futuristic underwater city powered by the temperature gradients in ocean water.
Designed by Shimizu Corporation, this conceptual city will include a floating sphere above the surface and a spiral structure plunging 4,000 meters into the deep sea, allowing humans to live, work, and even mine ocean-floor resources.
Powered by Nature:
It will harness Ocean Thermal Energy Conversion (OTEC) technology—an innovative method that generates electricity from the temperature difference between warm surface water and cold deep water.
The City’s Promise:
Fully self-sustaining energy
Food production and seawater desalination
Deep-sea exploration and rare metal extraction
Disaster-resilient infrastructure
If brought to life, Ocean Spiral won’t just be a city—it’ll be a blueprint for sustainable living in an age of climate and land challenges.
