Belgian architect Vincent Callebaut has revealed ambitious plans for a series of underwater eco-villages
The village concept could house up to 20,000 people in the future.
The project is still in research and development stage but the concept is impressive.
His Aequorea project imagines entirely self-sufficient, spiraling "oceanscrapers".
The submerged skyscrapers would reach to the sea floor mangrove-covered marinas on the surface of the world's oceans.
Jellyfish-like in appearance, each oceanscraper would be constructed using recycled plastics from the misleadingly named "Seventh Continent", or Great Pacific Garbage Patch.
Those concerned about the unsettling effects of strong currents, storms, or even earthquakes, need not worry: the towers' geometry and ballasting would counteract marine whirlpools and natural buoyancy, while the thickness of the outer shell would increase "from the sea surface downwards, to compensate for the strain caused by the increase in pressure."
Seawater would be desalinated for drinking, microalgae would recycle organic waste, and light would be provided through bioluminescence.
As well as living space, the Aequorea would house science labs, office space, hotels, sports fields, and farms across 250 floors and reach a depth of up to 1000 meters.
