Ten thousand I am across the heavens

Chapter 659 Ecological Cycle

Nanomachines are still popular among human beings. During this process, it will become more and more difficult for Trisolarans to infiltrate and destroy human beings. The government's ability to monitor civilians will also become stronger and stronger. In the face of foreign enemies, mankind has shown unprecedented unity, or in other words, mankind has enough reasons to establish a sufficiently powerful government.

After gradually solving their worries, humans also started the construction of the space fleet. Lan Nuo is also one of the important persons in charge of this aspect, and he is responsible for the construction of the ecological environment in the fleet, which can be regarded as his old profession. Of course, it is also one of the many things that Lan Nuo is responsible for.

The most important significance of constructing the ecological environment in the battleship is to realize the voyage between stars. Only when 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 not elegant to say so, if you have to describe it, it is to transform domestic waste such as feces into the daily needs of astronauts through ecological cycles.

The related technology Lannuo also had it before. Although they have not conducted such a long space voyage, they will design a similar structure when designing a battleship, 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 powers, so 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 energy to the ecological cycle like the sun.

When Lan Nuo designed the internal ecological cycle system of the battleship, he needed to consider that it could maintain the operation for at least 2000 years. If the star system around human beings wants to fly there by the spaceship that can be manufactured by existing technology, it needs to Hundreds of years, and more than that.

Even if there is enough time, the planets in that galaxy may not be suitable for survival, and there may not be an environment on that planet that can replenish the materials of the ecological cycle system, so 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 for a long time, heard the news that the design of the ecological cycle system should be enough to run for more than a thousand years, his eyes lit up, but there was no expression on his face, except for Lan Nuo, no one was aware of it. See what special reaction he had after hearing the news.

With such a long cycle time, it is theoretically possible to reach other planets even if the propeller is poor and the speed of navigation is slow.

……

If Zhang Beihai's attitude towards the fleet's ecological circulation system was a pleasant surprise, the Trisolarans would have been terrified when they saw this thing. Although Zhang Beihai had cheated him of a lot of technology before, he had already been tricked by the treachery and cunning of human beings. Despite their psychological shadows, Zhang Beihai's speculation still had a great impact on them.

Before that, Zhang Beihai concluded that Lan Nuo was an escapee, and all the technologies he developed were needed for interstellar navigation. After he defected, the Trisolarans once suspected that this inference was false, but now seeing this After the ecological cycle system of interstellar voyage can be realized, it is not calm again.

If these circulatory systems are equipped on battleships on a large scale, it is really possible for human beings to escape from 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 Trisolaris a Dark Forest Strike.

In fact, Lan Nuo had already obtained Zhang Beihai's previous statement of fooling the Trisolarans, and this is somewhat deliberate. Even if the Trisolarans slandered him as an escapee, not many people on Earth would believe it. Even if someone would believe it, he would not be able to shake his current position.

For this reason, the Trisolarans can only rely on the strength of the organization they have established on the earth to destroy this related plan. The greater the threat Lan Nuo poses to the Trisolarans, the more extreme their behavior will be.

If all the previous Wallfacers threatened the Trisolarans just because they couldn't find a new habitable planet, then Lan Nuo's threat to them now is equivalent to directly extinction of their civilization on their home planet.

This is undoubtedly quite terrifying, a hundred times more terrifying than the previous Wallfacers, it is equivalent to forcing the Trisolarans into the corner of life and death, and if they want to rely on humans to deal with Lan Nuo, they must Give humans more technology, at least more advanced technology than the nano-machines in the human body, otherwise, it is impossible to get rid of the monitoring of nano-machines.

And now the importance of killing Lannuo has been raised to a higher level than restricting the development of human technology. Even if human technology does not continue to improve, it will not be long before they can build interstellar spacecraft. As for gravitational wave antennas, blue Nuo has also made considerable progress.

This also means that even if human technology does not continue to develop, Lan Nuo may launch a dark forest attack on the earth and the trisolaran star, and then walk away.

In this way, it would be meaningless to restrict the development of human science and technology.

Lan Nuo did not tell Zhang Beihai the law of the dark forest. After all, it is too dangerous to let such a person know about this kind of thing. Zhang Beihai is the most likely to take the human fleet and leave, and then turn his back on humans and Trisolarans. Together to carry out the presence of Dark Forest Strike.

Lan Nuo was very worried that Zhang Beihai would really do such a thing. This guy had his own ideological stamp, and because of the change in the plot, Lan Nuo couldn't be sure what he was thinking now.

The ecological cycle system of the spacecraft was first constructed in the space station. For the spacecraft, it cannot simulate gravity like the space station.

The spaceship has to undergo frequent acceleration and deceleration, and in this environment, building an ecological roller will not have any good results. During the process of acceleration and deceleration, the people on the ecological roller will stagger. There is a forward four that only exists in theory, and everyone needs to soak the deep-sea acceleration fluid in the cabin, and it is even more impossible to build an ecological roller 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, and in a weightless environment, water will become a very dangerous thing.

In the process of human beings building space stations, similar accidents have occurred. The construction personnel in the space station did not realize the danger of water, and they were not vigilant enough for the water source leakage inside the space station. During the process, the personnel who went to make emergency repairs did not wear breathing aids in accordance with the rules and regulations.

As a result, a large amount of water sprayed out from the water pipe was absorbed on his body after touching him. The surface tension of the water and the weak gravitational force made the water all gather on his body.It was like being alive, attracted by him, and wrapped around his body, making him suffocate as if he had fallen into deep water.

More and more water was sprayed from the water pipe, and the staff kept struggling, but they couldn't 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. Struggling, the water covering his body still won't break away from him.

If it wasn't for the monitoring nearby, who saw his abnormality on the monitoring, and someone rushed to the scene to rescue him quickly, he might have become the first person to be drowned in space.

Therefore, the most important thing in the ecological cycle system is not to leak water. Most of the ecological cycles are carried out in a sealed environment. From the outside, there is no environment where birds are singing and flowers are fragrant. Some are just large metal boxes with warm light inside. The lamp, which emits light that simulates sunlight, grows a purple algae.

Before the birth of chlorophyll, organisms on earth absorbed the sun's sunlight through purple pigments.Violet absorbs light more efficiently than leaves, which reflect the highest-energy green light.

In this process, a large amount of oxygen will be released and carbon dioxide produced by breathing and so on will be consumed.These organic matter will be sent to the food synthesis chamber, and the oxygen will pass through the semi-permeable membrane and be transported to the oxygen storage system of the spacecraft.

After being fermented by 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 travel, natural meat is undoubtedly extremely precious.

As for the sorted waste on the spaceship, it will be injected into these metal boxes, decomposed by the fungi inside, and turned into relatively simple inorganic salts, which will be absorbed by photosynthetic organisms, transformed, and complete the cycle .

It does not build a complex ecosystem as imagined, and realize the balance of organisms in various systems. There is a huge difference from the ecological ring system that people imagine. It seems to give people a simple feeling, as if the technology is not enough. .

But in fact, the longer a system wants to maintain stable operation, the simpler the system itself, the better. The more complex the structure, the more likely problems will occur during the operation process, and the more troublesome it will be to solve these problems.

This is like a lot of military equipment.Obviously there are more advanced technologies, but they don't use them. Usually, they use technologies that are a generation behind civilians, because these technologies are stable, reliable, simple in structure, and not easily damaged in complex environments.Better adapt to the environment and changeable battlefield.

The same is true of the ecological cycle system on the battleship. The crew's nutritional balance and living comfort are not the top priority. The top priority is survival and the stability of the system itself.

After testing, the system has been in operation for three months, and the turbidity of the air in the space has remained almost unchanged. The oxygen content has decreased slightly at the beginning, and then maintained at a stable level. Although equipment such as semi-permeable membranes need to be tested Replacement, but it can be completely replaced with materials produced in the system, and there are almost no non-renewable consumables, which can achieve long-term circulation.

Although it has not been tested for a longer period of time, it is estimated that within five years, the system will not have any problems, and the next verification can only be left to time.

There are no spells in Trisolaris that can speed up the passage of time, but in the Shrouded Sky World, Lan Nuo has already tested this ecological cycle system with an array that speeds up the flow of time.

In about 300 years, the oxygen content and water content will begin to decline gradually, but at this time, if water or ice is replenished in time, the original state can still be restored immediately.

1000 Two hundred years or so, it will start to significantly affect the living conditions of the crew, and the air will start to become turbid, which is the result of the continuous accumulation of some chemical substances that cannot be filtered by semi-permeable membranes in the air, which is also inevitable. In this case, the semi-permeable membrane itself cannot be made particularly complicated, otherwise the self-circulation of the system cannot be realized.

However, this kind of problem is actually not a big problem on large spaceships. The semi-permeable membrane can be directly carried in the warehouse of the spaceship. A semi-permeable membrane can be filtered multiple times, so the amount that needs to be carried is very small, even if it needs to go back and forth between stars, it is an acceptable consumption.

However, there is almost no way to make up for it, and that is the loss of quality. In the process of recycling, some waste will inevitably be produced. This part has microorganisms that cannot be decomposed and cannot be absorbed by producers. As the structure becomes simpler, these wastes will continue to accumulate, leading to a gradual decrease in the quality available in the circulatory system. When it reaches about 3000 years, the total amount of substances will be completely unable to realize the cycle.

But this has been quite a long time. During this period, as long as water and carbon elements can be replenished, the system can continue to operate, and these substances are not particularly lacking in the interstellar space. Most planets Small amounts of the three elements carbon, hydrogen and oxygen can be found.

This seems to be a simple, even somewhat rudimentary circulatory system.The stability is far beyond the imagination of human beings, but because of its simplicity and practicality, it has begun to be equipped on large-scale voyage spacecraft, and humans have also started the first manned voyage in the solar system.

And this time the goal is directly Jupiter. The next plan for mankind is to build 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 with directly using the earth It is obviously more reasonable to use Jupiter's satellites to produce spaceships, which will cause huge damage to the earth's environment.

Moreover, human beings also have their own plans for the high orbit of the solar system, and this is a proposal put forward by Lan Nuo at the meeting of the Planetary Defense Council.
