Architect Bjarke Ingels is the lead author of the Oceanix City concept, which brings together many of the leading advances in resource efficiency. The project has already attracted the interest of UN representatives, as in the future it will help solve such pressing problems as hunger, lack of housing and threats from natural disasters. And, most importantly, where to move millions of people with the inevitable rise in the level of the world ocean.
The project is based on the new Biorock material. It is obtained by treating underwater minerals with electricity, resulting in a limestone coating three times stronger than concrete - but with positive buoyancy. It will protect the hulls of the hexagonal floating village platforms from the impact of the waves. One village accommodates living quarters for 300 people or several infrastructure facilities, and six connected villages are the “city”. A base settlement, it can drift, anchor or be towed out of the way of hurricanes and tsunamis.
In a floating city there are no big mechanisms, no transport, nothing that requires a lot of energy. Everyone moves on foot, by bike or boat, but there are several drones to monitor the situation in general. The buildings are built of bamboo, as it quickly grows back, all garbage is sorted and recycled - materials that are not suitable for these purposes are prohibited in the city.
The source of water is condensers of water vapor from the atmosphere. The upper part of the platforms is residential and working, the lower part is reserved for fish farms, shellfish colonies, beds with edible algae and aquaponics. Fish waste serves as fertilizer for plants, food residues are added to fish feed. There are no wheat fields, fruits and dairy products here, this will have to be brought from the shore. But the city fully provides residents with basic food and can exist autonomously for months - for example, during migration across the ocean.
