The rise of nanometers

It seems that the enthusiasm of workers in Sunflower County, which is under construction, has not been dampened by the ice and snow weather.

A high-strength pillar with a radius of 1.5 meters extends from the foundation to a height of 50 meters above the ground.

This is just a small pillar on the edge. In the center of the county, there is a 360-meter-high building, which is also the central pillar of the dome's protective layer.

The dome system will not limit the development of high-rise buildings, because the dome system and the new city are all designed integrally, and they will eventually be connected together to form a complete whole.

Although the protective layer of the dome system is only 300 meters high, and with the spherical design, the edge area is generally not too high.

In this way, if high-rise buildings want to coexist with the dome system, they must highlight the dome protective layer. This situation is actually allowed.

Of course, this situation is not common. Except for large cities such as Beijing, Shanghai, Guangzhou and Shenzhen, which have a large number of high-rise buildings, other small and medium-sized cities actually do not have many high-rise buildings.

With a height of 300 meters, it can accommodate a 75-story building based on a floor level of 4 meters.

If you really need to build a building with a height of more than 300 meters, you can choose two options. One is to build it within the dome system and then directly protrude the protective layer; the other is to choose to build it in an area without coverage.

For Sunflower County, which is dominated by agriculture, civil buildings in urban areas are generally only about 40 to 80 meters tall, which is not as high as agricultural factories in the suburbs.

Agricultural factories in the suburbs are usually 40 to 50 stories high, with an overall height of about 200 to 250 meters.

The Federation's technological development is very rapid. This is not only reflected in the aerospace field, but also in other fields.

Although the Mobei and Mongolian prairie and desert Gobi Desert areas have undergone extensive ecological transformation due to agricultural needs, this does not mean that the federal government will completely destroy the original local ecology.

The advancement of science and technology has made humans more and more efficient in obtaining materials, energy, and food. Traditional open-air agriculture and semi-natural grazing are increasingly unable to adapt to the development of the times.

For example, in Sunflower County, a 40-story agricultural factory covering an area of ​​20,000 acres has a year's agricultural productivity that is almost equivalent to about 2 million acres of open-air farmland.

This is such a terrible production efficiency. The total population of the Federation is currently only about 1.92 billion. If we want to maintain the entire population and live a prosperous life, we will need about 2.4 billion acres of arable land, 600 million to 1 billion acres of fruit forest land, and 1.2 billion acres of fruit forest land. Pastures, as well as quite large land-based farms, freshwater and seawater farms.

If these land resources were all obtained from nature, the current land area of ​​the Federation would actually be relatively scarce. Even with Oceania and the South Pacific, two vast and sparsely populated areas, it would still be slightly insufficient.

Especially after the federal government encouraged childbirth, the first wave of baby boom in the country was rising rapidly.

It is expected that the total population will reach 2.4 to 2.5 billion around 2030, reach a peak around 2040, that is, the total population will be 3.2 to 3.4 billion, and then remain stable.

For such a huge population to maintain a high level of affluence, the resources and energy they need to consume every day are extremely huge.

However, the population cannot be suppressed excessively, otherwise it will have the opposite effect. Once negative population growth occurs, not only will it be impossible to maintain development, but there will also be a vicious cycle of bad money chasing good money.

Unless immigration is completely blocked, the influx of a large number of low-quality people will only bring about a superficial decrease in labor costs, which will then lead to a serious gap between the rich and the poor, thus dividing society.

Although the federation has suppressed the gap between rich and poor, it does not mean that it will not resurgence. The 300-year dynastic cycle law also applies to modern countries.

There is only one way to break this fate, and that is to break through the current social limitations and promote to an interstellar civilization.

This is actually similar to the promotion of immortal cultivators. If you fail to overcome the tribulation, you will die directly.

The same is true for the promotion of civilization.

Why did the Zhou Dynasty have a national destiny of eight hundred years? The Central Plains Dynasty that followed could hardly break through the limit of three hundred years.

The reason lies in the differences in the external environment.

During the Spring and Autumn Period and the Warring States Period, the major states in the Central Plains continued to annex surrounding areas while at the same time fighting each other, resulting in the continuous expansion of the Xia's sphere of influence.

The subsequent dynasties basically expanded to the limit of the feudal era (restrictions on communication and transportation), and then became complacent, making it difficult to break through the three-hundred-year curse.

In modern times, even though many countries are so-called "modern countries," they still have difficulty breaking through the three-hundred-year curse.

On the one hand, Blue Star's natural resources are limited, and on the other hand, the gap between rich and poor in educational resources is serious.

There are too many mountains within human civilization, and it cannot plunder external resources (that is, develop extraterrestrial resources). It can only fall into terrible internal strife.

Some of the current strategies of the Federation can be summarized in a few sentences: upgrading the quality of the entire population, efficient use of resources, and exploring extraterrestrial resources.

The development of agriculture is part of the efficient use of resources.

By replacing open-air farmland, pastures, forest farms, and fisheries with a large number of agricultural factories, even if external resources are completely cut off, the entire population can still maintain a prosperous life with internal resources.

In the northern region of China, the agricultural factories currently under construction cover an area of ​​7.23 million acres, equivalent to 500 million acres of open-air farmland in the northern region.

Although the Little Glacier climate is becoming more and more obvious, the Federation still seems to be able to handle it with ease. The grain stored in stock every year is enough to ensure that the entire population can eat for three years. This three-year stockpile means that no new grain is produced at all.

According to the current federal agricultural technology, even if the Yellowstone volcano erupts, the world enters an ice age, or an asteroid hits the Blue Star, it is impossible to destroy the entire food production capacity of the federation.

For example, those agricultural factories in the northern region of China are equivalent to about 500 million acres of open-air farmland.

There are also many agricultural factories in the southern mainland, Oceania region, and South Pacific region, which is equivalent to about 330 million acres of open-air farmland.

If the federal government enters a state of emergency, the lost open-air agricultural areas can be replenished with agricultural factories within three years.

Therefore, the disastrous Little Glacier climate is nothing but a trivial matter to the Federation.

The work of transforming northern cities is proceeding in an orderly manner, and Xiangkui County is just an insignificant city among them.

To the south of Xiangkui County, about 124 kilometers deep in the Gobi Desert, a nuclear fusion power station hidden underground is also put into operation today.

On the surface, this nuclear power plant is a thermal power station that relies on the mining of surrounding coal mines to generate electricity and produce gas. It is also the new energy core of Dongfang Province.

According to the design, this horse power station named "Heishitan Power Station" has a power generation of 120,000 megawatts and a total of 6 Yugu 4-type nuclear fusion generator units.

The maximum power generated by a single unit is 30,000 megawatts, which is the largest nuclear fusion power generation unit in the federal government.

Of the 6 units at Heishitan Power Station, 4 are conventional power supply units, 1 regulating unit and 1 standby unit.

There are currently 47 nuclear fusion power stations in production in the mainland and Oceania regions, with a total power generation of 3.28 million megawatts and a capacity of 12,000 kilowatt-hours per year.

But this is not enough. Suiren is already developing a nuclear fusion generator unit with a single-machine power generation of 100,000 megawatts, and China National Nuclear Corporation is also studying the 50,000-megawatt Jinwu 5 type.

It is expected that in the next five years, the annual installed capacity of nuclear fusion generators will reach 2 to 3 million megawatts.
