However, now the main role of this maritime city is not to engage in production and manufacturing, this huge sea fortress, all the space inside is to meet the needs of human life. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

In this completely enclosed sea fortress, which is completely enclosed from the outside, it is divided into 5 floors.

Divided into 5 layers, it is more of a 5,000 square kilometer maritime city than a 1,000 square kilometer maritime city.

Inside this huge sea fortress, except for the first floor, which is only 50 meters high, is used as an energy storage and a small number of special factories, the remaining four floors are integrated urban areas such as agricultural farming, living houses, commercial centers, hotels, schools, and parks.

Each of these layers is more than 100 meters high, and the sky can fully simulate the natural climate environment, except that there is no real sun, in such an internal environment can simulate the formation of a variety of climate environments, can be a good weather with a clear sky, but also can rain, wind and snow.

There are also buildings and residential buildings on each floor, but the height of each floor is limited to only 100 meters, and the height of these houses and buildings is limited to less than 70 meters.

The streets and environments are the same as those of a normal city, the only difference is that the environment of the entire space is full of all kinds of high-tech.

For example, the buses and private cars on each floor are all electric and driverless, and these buses and private cars can be charged wirelessly while driving. In the middle of the city's streets, more than ten meters high, there is also a maglev train that can run inside a vacuum tube, which is the super high-speed rail project that is currently being studied by various countries.

To put it simply, inside this huge sea fortress is a high-tech futuristic city that highly simulates the external natural environment.

In other words, such a city can be built not only on the sea, but even on Mars, because this sea fortress is a city that can be completely self-sufficient.

For example, there is a huge desalination plant at the bottom of the floor, and there is a nuclear power plant capable of generating 1 trillion kilowatt-hours of electricity per year.

For example, the equipment that highly simulates the external natural environment in the sky on each floor, and the large number of public transportation, all of which require electricity to drive.

And the areas where various crops are grown on each floor also require a lot of electricity, because these areas where crops are grown are not traditionally soil-grown.

These areas where crops are planted are all in huge buildings, and whether it is vegetable cultivation, rice and wheat, the main grain planting, and various fruit trees, all of which are planted without soil.

The photosynthesis required by all plants is also highly intelligent LED light, which will be adjusted according to the different stages of the plant.

The benefits of this way of planting are great, the most simple and intuitive point is that it can be harvested several times more than the normal way of planting in the outside world in a limited space.

For example, if you only grow some daily vegetables such as lettuce, you only need to use shelf planting equipment with a height of only 1 meter per floor to meet the planting needs of these vegetables.

To use the simplest analogy, if a building with a height of 70 meters and an area of 1,000 acres is used to grow rice, and the 70-meter building is divided into 14 floors, then it is equivalent to having 14 times more planting than the outside world.

That is to say, planting 1 acre of rice on normal land in the outside world, using this high-tech soilless planting method, then the harvest of an acre of land is equivalent to the harvest of 14 acres of land in the outside world, or even more than this amount, because there is no natural disaster in such an indoor environment, and the use of high-tech and more scientific planting methods, the yield is also higher than that of normal land planting in the outside world.

And now this huge sea fortress, the sea city, is designed to live in a normal population of 20 million people, and the maximum number of residents is 30 million people.

The four floors have a total base area of almost 4,000 square kilometers, and all of them are built-up areas.

With such a huge built-up area, if you use the real city as a reference, taking the magic capital as an example, all the districts under the jurisdiction of the magic capital have a total area of 6,340 square kilometers, while the real inhabited built-up area is only about 1,500 square kilometers.

But in this 1,500 square kilometre built-up area, 23 million people live in these areas.

Now this maritime city has a total of 5 floors, and if you count the top floor, it is 6 floors, which means that the total area of this maritime city that can be used for human activities is nearly 6,000 square kilometers.

Moreover, all of these areas are still built-up areas, and such a large area is only planned to be inhabited by 20 million people, which is simply too loose compared to the outside megacities.

Because if this maritime city is allowed to live in a normal 20 million people, then the per capita residential area of 20 million people is as high as 500 square meters.

In other words, if it is simply calculated according to the per capita residential area, then everyone lives in a luxury house.

Although it is not true that everyone can enjoy 500 square meters of living space, in the residential planning of the entire maritime city, the smallest single apartment is 50 square meters in size, and the largest mansion is 5,000 square meters.

And this is just the residential area, there are also various commercial areas, agricultural planting areas, schools, parks, and other public areas.

At this moment, when Yang Yu listened to the general introduction of a senior technician, he couldn't help but feel a feeling in his heart.

"Once this maritime city is built, there is no doubt that I will become the world's largest real estate developer and the world's largest landlord, no, it should be the city owner!" After sighing, Yang Yu thought of a most critical question, so he continued to ask: "How much does it cost to build such a city?"

In fact, this is the most important issue, because building a maritime city is a great vision, but the cost aspect is also an extremely important issue.

At the same time, the design plan of the city, whether all the technologies covered can be fully achieved, such as the indoor sky that highly simulates the natural environment, and whether the technology involved is really fully up to standard.
