Nanomachines are still becoming more popular among humans. In this process, it will become more and more difficult for Trisolarans to infiltrate and destroy humans, and the official's ability to monitor civilians will become stronger and stronger.
In the case of foreign enemies, human beings have shown unprecedented unity, or in other words, human beings have enough reasons to establish a strong enough government.
After gradually solving their worries, mankind also began to build a space fleet. Lan Nuo was also one of the important persons in charge in this area, and he was responsible for the construction of the ecological environment in the fleet, which was also his old profession.
Of course, it is one of the many things that many Lannos are responsible for.
The most important significance of building an ecological environment within a warship is to realize navigation between stars. Only if there is an ecological circulation system inside the spacecraft, can the materials on the spacecraft be enough to support the long voyage between stars.
Although it is a bit unsightly to say this, if I have to describe it, it is to re-convert domestic waste such as feces into the daily needs of astronauts through ecological recycling.
The Lannos had related technology before. Although they had not conducted such a long-term space voyage, they would design a similar structure when designing battleships and achieve stable operation in space.
The basic rules of animals and plants in the Trisolaran world are not much different from other worlds, at least in terms of animals and plants without extraordinary power. Therefore, similar means can be used to build an ecological cycle system.
The huge energy provided by controllable nuclear fusion is enough to make the ecological cycle run healthily, and it can continuously replenish the ecological cycle with energy like the sun.
When Lanno designed the ecological cycle system inside the battleship, he needed to consider that it could maintain operation for at least two thousand years. If he wanted to fly to the star systems around humans with a spacecraft that can be manufactured with existing technology, he would need to
Hundreds of years have passed, and that's not all.
Even if there is enough time, the planet in that galaxy may not be suitable for survival, and it may not be possible to find an environment on that planet that can replenish the materials of the ecological cycle system. Therefore, the materials of the system may not be replenished for thousands of years.
After testing one star after another, it is possible to find a habitable planet.
Zhang Beihai, who has been living in seclusion here in Lan Nuo, couldn't help but his eyes lit up after hearing the news that the ecological cycle system was designed to be able to operate for more than a thousand years, but there was no expression on his face. No one except Lan Nuo was aware of it.
What special reaction did he have after hearing the news?
With such a long cycle time, even if the propeller is poor and the sailing speed is slow, it is theoretically possible to reach other planets.
…
If Zhang Beihai's attitude towards the fleet's ecological cycle was a surprise, the Trisolarans would have been frightened when they saw this thing. Although Zhang Beihai had cheated him of a lot of technology before, he had been tricked by human beings' cunning and cunning.
Despite their psychological shadow, Zhang Beihai's speculation still had a great impact on them.
Before that, Zhang Beihai concluded that Lan Nuo was an escapeist and that all the technologies he developed were needed for interstellar navigation. After his defection, the Trisolarans once suspected that this conclusion was false, but now they see this
After the ecological cycle system that could realize interstellar voyages, it became uneasy again.
If these circulatory systems are equipped on battleships on a large scale, it will really be possible for human beings to leave the earth and go to other planets to survive. Once the future described by Zhang Beihai appears, Lan Nuo may turn around and give the earth and the Trisolaran planet a
Dark forest strike.
Lan Nuo had actually gotten the statement from Zhang Beihai that he had previously deceived the Trisolarans. This seemed to be somewhat intentional. Even if the Trisolarans slandered him as an escapee, not many people on Earth would believe it.
Even if someone believes it, it can't shake his current status.
For this reason, the Trisolarans can only rely on the power of the organizations they have established on Earth to sabotage this related plan. The greater the threat that Lan Nuo poses to the Trisolarans, the more extreme their behavior will be.
If all the previous threats to the Trisolarans from the Wallfacers were to prevent them from finding a new livable planet, then the threat that Lan Nuo poses to them now is equivalent to directly annihilating the civilization on their home planet.
This is undoubtedly quite terrifying. It is a hundred times more terrifying than the previous wall-facers. It is equivalent to forcing the Trisolarans into a corner of life and death. If they want to rely on humans to deal with Lan Nuo, they must
Give humans more technology, at least technology more advanced than the nanomachines in the human body. Otherwise, it will be impossible to get rid of the monitoring of nanomachines.
And now the importance of killing the Lannos has increased to a higher level than restricting the development of human science and technology. Even if human science and technology does not continue to improve, it will not be long before we can build interstellar spacecraft, and in terms of gravitational wave antennas, Blue
Nuo has also made considerable progress.
This means that even if human technology does not continue to develop, Lanno may still launch a dark forest attack on the earth and Trisolaris, and then fly away.
In this way, it would be meaningless to restrict human technological development.
Lan Nuo did not tell Zhang Beihai about the laws of the dark forest. After all, it was too dangerous for such a person to know such things. Zhang Beihai was the most likely to leave with the human fleet and then backhandedly attack humans and Trisolarans.
Let's fight together in the dark forest.
Lan Nuo was very worried that Zhang Beihai would really do something like this. This guy had his own ideological seal, and because of the changes in the plot, Lan Nuo couldn't be sure what he was thinking now.
The ecological circulation system of the spacecraft was first constructed in the space station. For the spacecraft, it is not possible to simulate gravity like in the space station.
The spacecraft needs to accelerate and decelerate frequently, and in this environment, establishing an ecological roller will not have any good effect. During the process of acceleration and deceleration, the people on the ecological roller will stagger around. In addition, there are
Forward IV, which only exists in theory, requires everyone to soak in deep-sea acceleration fluid in the cabin, and it is even more impossible to build an ecological drum inside the spacecraft.
Therefore, the simulated ecological laboratory is in the center of the space station, where it does not rotate and is in a state of weightlessness. In a weightless environment, water will become a very dangerous thing.
In the process of human beings building the space station, similar accidents occurred. The construction personnel in the space station did not realize the dangers of water and were not vigilant enough about water leaks inside the space station. In one case, a water source leaked in the space station.
During the process, the personnel who went for emergency repairs did not wear breathing assistance equipment in accordance with the rules and regulations.
As a result, a large amount of water sprayed out from the water pipe adsorbed on his body after contacting him. The surface tension of the water and the weak gravity caused all the water to gather on his body. It was like there was life.
Likewise, it was attracted to him and wrapped around him, suffocating him as if he had fallen into deep water.
More and more water sprayed out of the water pipe, and the staff kept struggling, but they could not swim out of the water like a drowning person. There was no gravity in the weightless environment, and naturally there was no way to use the buoyancy of the water. No matter how hard he tried,
Despite struggling, the water covering his body still wouldn't break away from his body.
If there hadn't been surveillance cameras nearby that saw his abnormality and someone quickly rushed to the scene to rescue him, he might have become the first person to drown in space.
Therefore, the most important thing in the ecological cycle system is to prevent water leakage. Most ecological cycles are carried out in a sealed environment. From the outside, there is no environment with birds singing and flowers fragrant. There are just large metal boxes with warm lights inside.
The lamp can emit light that simulates sunlight, and a purple algae is cultivated in it.
Before the birth of chlorophyll, organisms on the earth absorbed sunlight from the sun through purple pigments. Compared with leaves that reflect away the most energetic green light, purple absorbs light more efficiently.
During this process, a large amount of oxygen will be released, and the carbon dioxide produced by respiration will be consumed. These organic matter will be sent to the food synthesis cabin, and the oxygen will be transported through the semi-permeable membrane to the oxygen storage system of the spacecraft.
After the fermentation of fungi, organic matter will become food that can be used by humans. If you want to raise animals, you can also do it. However, in space navigation, natural meat is undoubtedly extremely precious.
As for the waste on the spacecraft, after being classified, it will be injected into these metal boxes, where it will be decomposed by the fungi inside and turned into relatively simple inorganic salts. After being absorbed and transformed by organisms performing photosynthesis, the cycle will be completed.
.
It is not as imagined to build a complex ecosystem to achieve the balance of organisms in various systems. It is very different from the ecological ring system that people imagine. It seems to give people a crude feeling, as if the technology is insufficient.
.
But in fact, if you want a system to maintain stable operation for a long time, it needs to be as simple as possible. The more complex the structure, the more likely problems will occur during operation, and the more troublesome it will be to solve these problems.
This is like a lot of military equipment. Although there are more advanced technologies, they are not used. They usually use technologies that are one generation behind civilian use because these technologies are stable, reliable, simple in structure, and not easily damaged in complex environments. More
Able to adapt to the environment and changing battlefields.
The same is true for the ecological cycle system on a battleship. The nutritional balance and comfortable life of the crew are not the top priority. The top priority is survival and the stability of the system itself.
After testing, the system has been running for three months. The turbidity of the air in the space has remained almost unchanged. The oxygen content dropped slightly at first and then remained at a stable level. Although equipment such as semipermeable membranes need to be
Replacement, but it can be completely replaced with materials produced in the system. There are almost no non-renewable consumables, and a long-term cycle can be achieved.
Although it has not been tested for a longer period of time, it is estimated that the system will not have any problems within five years, and the next verification can only be left to time.
There are no spells in the Trisolaran World that can speed up the passage of time, but in the Zhetian World, Lan Nuo has already had individuals use formations to speed up the flow of time to test this ecological cycle system.
In about three hundred years, the oxygen content and water content will begin to gradually decrease. However, if water or ice is replenished in time at this time, it can still return to the original state immediately.
Around one thousand two hundred years, it will begin to significantly affect the living conditions of the crew. The air will begin to become turbid. This is the result of the continuous accumulation of chemicals in the air that cannot be filtered by the semi-permeable membrane. This is also inevitable.
In this case, the semipermeable membrane itself cannot be made particularly complex, otherwise the self-circulation of the system cannot be achieved.
However, this is not a big problem on a large spacecraft. The semi-permeable membrane can be carried directly in the warehouse of the spacecraft. If it is replaced directly, it can also complete the filtration of the air. One such filtration can last for hundreds of years, and one time
A semi-permeable membrane can be filtered multiple times, so the amount needed to be carried is very small. Even if it needs to be traveled back and forth between stars, it is an acceptable consumption.
However, there is one thing that is almost impossible to make up for. That is the loss of quality. During the recycling process, some waste will inevitably be produced. This part cannot be decomposed by microorganisms and cannot be absorbed by producers. Even if the system is as clean as possible,
As the structure becomes simpler, these wastes will continue to accumulate, causing the quality available in the circulation system to gradually decrease. By about three thousand years, the total amount of matter will be completely unable to be recycled.
But this has been a long time. During this period, as long as water and carbon elements can be replenished, the system can continue to operate. These materials are not particularly lacking in the interstellar space. Most planets
The three elements carbon, hydrogen and oxygen can be found in small amounts.
This seems to be a simple, even crude, circulatory system. Its stability far exceeds current human imagination, but because of its simplicity and practicality, it has begun to be equipped on a large scale on long-distance spacecraft, and humans have also begun the first mission in the solar system.
The first manned voyage.
This time, the target is directly Jupiter. Humanity’s next plan is to establish a base on Jupiter. To be precise, it is a satellite of Jupiter. Jupiter, with a large number of satellites, can provide many natural spacecraft production bases. Compared to directly using the earth,
Using resources to produce spacecraft will cause huge damage to the earth's environment. Using Jupiter's satellites to produce spacecraft is obviously a more reasonable way.
Moreover, humans also have their own plans for the high orbit of the solar system, and this was a proposal put forward by Lanno at the meeting of the Planetary Defense Council.
