Ocean Spiral $26 billion underwater city concept, could be ready in 15 years.
Japanese architectural and engineering firm Shimizu unveiled Ocean Spiral, a fully sustainable, eco-friendly underwater city.
The futuristic city, a floating sphere around 500 meters just below the surface of the sea, featuring residential, and commercial zones, would cost around $26 billion to build.
“It offers enormous potential for ensuring effective and appropriate cycles and processes in the Earth’s biosphere.”
Approximately 70% of the earth’s surface is covered by the ocean, and the ocean itself consists of approximately 80% deep sea.
The deep sea offers enormous potential for ensuring effective and appropriate cycles and processes in the earth’s biosphere.
Unfortunately, we have yet to make the most of this potential.
This large-scale concept seeks to take advantage of the limitless possibilities of the deep sea by linking together vertically the air, sea surface, deep sea, and sea floor.
Strength: Realized using triangular acrylic plates measuring 50m each a side. Reinforced using semitransparent FRP ribs.
Cleaning: Using microbubbles and other means to prevent the adhesion of marine life.
Joints: Sealing against water, absorbing displacement etc.
