Chapter 314 Artificial Atmosphere

Moon in perilunar orbit.

A large spaceport stands here.

This space port looks familiar, it is exactly the same as the unfinished space port in the geosynchronous orbit of Civilization Science City.

Inside the spaceport.

One after another, the colonial starships parked quietly, and below them was the devastated moon.

Compared with the earth, the moon is a completely different world.

Although humans landed on this planet decades ago, their ability to develop it is infinitely close to zero.

Whether it is the lunar exploration project or the construction of a scientific research station on the moon, it is destined to be some projects that cannot make ends meet.

Not to mention building a base city here that can accommodate a large number of human beings like the City of Civilization and Science.

This kind of thinking would have been a fantasy a few years ago, and it was unrealistic.

But as the Civilized Science City continues to refresh the upper limit of human technology, these dreams that seemed unrealistic in the past are being realized bit by bit.

Guanghan City.

first district.

This is the first lunar urban area built by Guanghan City Engineering Committee.

Of course, from the perspective of urban area, the area of ​​the first urban area of ​​Guanghan City is far from being able to compare with the several major urban areas in the Civilized Science City, especially the third urban area of ​​the Academy of Civilization and Science.

In fact, the first urban area of ​​Guanghan City is just an experimental urban area to verify whether human beings can survive in the urban area for a long time in a closed environment.

The crew of the colony starship are the first residents of this experimental city.

The first district of Guanghan City has a total area of ​​more than 50 square kilometers.

This area is at most about the size of the urban area of ​​a small county in Huaguo.

But considering that the site where this "county" was built was the moon, one can imagine how much the City of Civilization and Science has paid for it.

of course.

What the City of Civilization and Science has paid the most is not to build these buildings on the moon.

What Lu Chen and the others paid the most was to make this closed urban area achieve an ecological cycle.

This is not an easy task!

In order to study the artificial ecological cycle, the United States has carried out two famous projects, Biosphere [-] and Biosphere [-].

But without exception, both projects failed.

However, in the eyes of Lu Lin, a biology expert at the Academy of Civilization Sciences, these two projects have not failed.

It can only be said that they did not achieve the goals expected by humans.

Undoubtedly, Biosphere [-] and Biosphere [-] are two artificial miniature ecological circulation systems.

Especially Biosphere 1, which covers an area of ​​more than 14 square meters and has a volume of [-] cubic meters.

But after maintaining it for more than a year, the ecosystem collapsed.

As for the reason, according to the research of the scientists, it is because the oxygen inside Biosphere [-] cannot participate in the normal circulation.

But Lu Lin has a different view on this.

Any ecosystem in the universe will eventually go to destruction.

Since Biosphere [-] is an ecosystem, it is normal for it to collapse.

But the collapse of the ecosystem is also different.

Such as the earth's ecosystem.

Ecosystems have collapsed far more than once in Earth's long history.

Every time an ecosystem collapses, it will cause a mass extinction.

However, compared with the artificial ecosystem of Biosphere [-], the stability of the earth's ecosystem does not know how many blocks it will take.

Maybe the earth's natural ecosystem collapses every few hundred thousand or millions of years.

However, Biosphere [-] can only last for a short period of more than a year.

The two don't seem to exist in the same order of magnitude at all.

But considering the size of the two, this seems to be a very understandable thing.

The total area of ​​the earth is as high as 1.5 million square kilometers, and its volume must be multiplied by the height of an atmosphere.

Therefore, the scale of the Earth's ecosystem surpasses that of Biosphere [-] by an order of magnitude, and the stability of the two is naturally not at the same level.

In the earth's ecosystem, even if something goes wrong.

For example, after so many years of wanton destruction of the environment by human beings, the earth's ecosystem can still continue to operate tenaciously, because the earth's ecosystem is large enough to support human squandering at will.

Bio[-] was different.

It was too small. Although it was carefully designed by scientists before it was built, with the technology at that time, humans did not have any means to interfere with the operation of the ecosystem.

Biosphere [-] collapsed because oxygen was absorbed by the concrete walls that enclosed the ecosystem as it participated in the cycle.

As a result, the oxygen concentration inside Biosphere [-] continued to decrease, which eventually led to the mass extinction of the internal organisms.

However, in this process, scientists can only do nothing about it, without any human intervention.

Therefore, the collapse of the ecosystem of Biosphere [-] was not due to the failure of the construction of this ecosystem, but its small nature, which has already determined that this ecosystem is fragile.

From this perspective.

Guanghan City seems to be much better.

Because the total area of ​​its first urban area alone has exceeded 50 square kilometers. In terms of area, it is thousands of times that of Biosphere [-].

If there is no human intervention, perhaps this ecosystem will collapse naturally after decades or even centuries.

It's a pity that Guanghan City was not built for scientific research, but for immigration here.

Since people want to immigrate, it is destined that there will be a large number of residents living here in this city in the future. From this point of view, it may not take a few decades, maybe a few years, the ecological system of Guanghan City will be replaced by the residents who immigrated here. Crash.

of course.

The premise of all this is that there is no means of human intervention in the Civilized Science City.

In fact, since the Academy of Civilization Sciences proposed to establish a base city on the moon to avoid the disaster of an asteroid hitting the earth, this issue has been fully considered.

Regarding the ecosystem of Guanghan City, the Academy of Civilization Sciences not only has the means to regulate it, but it is also so strong that it explodes!
One of its most fundamental methods is gravity control!

Its specific manifestation is the canopy system covering about five kilometers above Guanghan City, or it is called an artificial atmosphere!
One of the most important factors for the birth of life on the earth lies in its atmosphere.

The most important thing in the earth's atmosphere is the ozone layer.

How important is the ozone layer?
First, cut off 99% of ultraviolet rays, and second, keep the earth warm.

If there is no atmosphere, you can refer to the moon with almost no atmosphere.

On the moon, the temperature can reach more than 120 degrees during the day and more than minus 180 degrees at night.

Compared with this, the long gap between day and night on the moon seems to be nothing.
