To counter the wild urbanization and the destruction of the territory, there are already those who are thinking of building futuristic floating cities, naturally eco-sustainable and self-sufficient.
It is not science fiction, because the well-known Chinese construction group Cccc has commissioned the British architecture firm AT Design to design a first prototype of a floating city: a floating metropolis that it is hoped to be able to start building in 10-20 years off the coast of Honk Kong.
We do not know if this urban center will ever come to light, but we are certainly not in the presence of crazy visionaries, because this Anglo-Chinese partnership has already collaborated profitably in the development of Port City, a reclaimed island of 230 hectares located off the coast of Colombo. , in Sri Lanka.
In the face of criticism, CCCC is ready to bet on the feasibility of the project, explaining that the technology adopted for this future city by the sea will be the same as that already used by the company for the construction of the 31 km bridge currently under construction between the cities of Hong Kong, Macau and Zhuhai. Part of that bridge is in fact flanked by a 150 m underwater tunnel, intended to house prefabricated concrete boxes.

Beyond the shared ecological aim of the project, that of avoiding the further growth of cities on the mainland with the consequent problems of congestion, pollution and subtraction of space from greenery and fertile land, the British designers are also aware of its tourist value, because Chinese investors are ready to create never-before-seen attractions and to respond to the will of Asian citizens to explore underwater possibilities.
To understand what this futuristic ocean city will be like, at the moment we have to content ourselves with only some graphic elaborations and the explanation of the project by the AT Design group. Over an area of approximately 10 sq km, the construction of a series of hexagonal modules in floating concrete is envisaged, linked together by underwater tunnels to form real artificial islands.
The floating city would then be self-sufficient, eco-sustainable and with zero emissions, because special modules used as greenhouses, nurseries and farms would guarantee the production of food, while renewable sources would take care of energy supply, thanks to hydroelectric generators, artificial water basins. rain, photovoltaic panels and the waste combustion process.
Everything will be in the name of sustainable mobility, because the modules will be connected not only to each other but also to the mainland by means of underwater tunnels with sidewalks, roads and carriageways, where it will be possible to circulate only with electric cars or public transport without polluting emissions. . Then get ready to travel with submarines, which will be one of the main means of transport, in order to avoid pollution and congestion in the floating city.

There will also be large green spaces, with vertical gardens interconnected with the public green both above and below the water surface, and also the recycling of waste will follow the rules of eco-compatibility, thanks to special collection centers that will provide for the disposal.
Tourists, expected in droves, will have the most varied possibilities of choice between attractions and entertainment: bars, restaurants, museums, galleries, underwater hotels, theme parks and even large spaces both above and under water will arise everywhere, which will allow the performance of concerts of the kind we are used to seeing in the biggest stadiums. Good news also for VIPs: beyond the seaport intended for all the needs of civil navigation, it will be possible to find large basins for yachts and private boats.

Building on the sea no longer seems a utopia. In addition to this project, there are numerous others, equally futuristic, which aim to displace the cities that are now increasingly unlivable. Staying in England, Phil Pauley's London studio has already designed Sub-Biosphere 2, an underwater center where special domes would recreate the same conditions as life on the earth's surface.
Do not be afraid to miss the earth from under your feet: the future of humanity may be farther and farther from the mainland.
