Deep Space Fleet

Brother Zhao smiled, "Insufficient cooling capacity leads to insufficient sewage treatment capacity. Do you know how much water each of us has on average?"

Zhang Yuan shook his head.

Zhao Qingfeng stretched out a hand: "5 tons, the entire spacecraft has more than 2 million tons of water, and each person has only 5 tons of water on average. And how much does the average person on earth have? 0.13 cubic kilometers, which is 130 million tons. "

"One man has fifty times as much as we have combined!"

"Think about it, we have such a small amount of water, the self-purification ability is almost zero. The used water is divided into several levels for treatment, drinking water, industrial water, domestic sewage, etc. Among them, the drinking water needs to be distilled again. How much energy?"

"Energy itself is not a problem. Nuclear fusion brings a lot of energy, but if the heat generated by these industries is not dissipated in time, it will cause heat accumulation problems... so that the heat dissipation capacity is completely insufficient."

"Oh, that's what I said." Zhang Yuan nodded, and he understood that the industries in the spaceship are one after another.

A single sewage treatment unit is not complicated, but it becomes quite troublesome when linked with other things.

An error in any link will lead to the collapse of the entire system. And a spaceship must retain a fairly high fault tolerance rate.

He said: "So, the heat that we can't handle at present, should we simply throw it out through the emission of matter?"

"It's like this. Replenish material once we reach Europa... But after arriving at Jupiter, there will be no more resources to replenish, and everyone will have to hibernate. At that time, the population will drop sharply, and the heat dissipation capacity will be sufficient."

In the process of chatting like this, the rail car arrived at the first stop, which is the core industrial area.

This is a vacuum zone, plus there is no gravity, and no external force can be borrowed, so it is extremely troublesome to move.

For the convenience of the astronauts, electromagnetic generators are placed on the road. As long as the infrared probe on the spacesuit is aligned, after a signal is emitted, it will generate a certain electromagnetic force to suck people in.

Zhang Yuan is no stranger to these devices, and quickly mastered the knack of using them, flying leaps and bounds in the corridor.

Through a thin layer of glass, many workers are working in the production room.

Zhang Yuan saw an old acquaintance——Ye Kaifu was concentrating on something on an electronic screen, but he didn't run over to say hello.

In fact, there is no need for so many people in the production room, but in order to increase everyone's proficiency, the management decided to train them with saturated work. Anyway, it is always right to cultivate.

The entire set of industrial processes has been visited at a glance, and there are not many machines in operation.

There are advantages and disadvantages to space industrial production inside the spacecraft.

Let me talk about the shortcomings first, the first is the very routine process of "extraction", there is no way to directly achieve it.

To give a simple example, put water and oil in a bottle and then shake it vigorously. Using the different solubility of different solutes in water and oil, the solutes are separated and extracted. This process is called "extraction". Implementation on Earth is very simple. But it is difficult in space, where water and oil cannot be separated due to weightlessness.

In a similar way, chemical processes such as rectification, absorption, precipitation, and bubbling cannot be easily realized in a gravity-free zone.

However, because there is no gravity, the centrifuge thing started to shine.

As long as a centrifuge is used, it is equivalent to creating artificial gravity, rectification, absorption, precipitation, and bubbling can be completed again.

Moreover, the centrifuges in space are no longer disturbed by the gravitational environment, and can be made larger, and more pure substances can be purified and separated.

Brother Zhao asked: "This high-gravity rectification machine can generate a gravitational acceleration of 500 g. How many times is its separation speed faster than the rectification tower on the earth? Do you know the formula?"

Zhang Yuan frowned and thought for a minute.

What is the correlation formula of the packed tower...

"7.9 times!"

Zhao Qingfeng was slightly surprised, he didn't expect this kid to know such an unpopular formula.

However, he was only slightly surprised. For geniuses, he naturally had expectations for geniuses.

"Very well, the speed of rectification is proportional to the 1/3 power of acceleration. As long as the rotation is faster, the speed of chemical purification will be faster."

"On our moon, there is a very complete set of silicon purification industry, but unfortunately you can't see it now. Through repeated acidification and distillation, it is possible to extract extremely high-purity pure silicon ingots, with a purity of about 99.9999...%, probably 15 nines, and the industry on the earth can only extract 11-12 nines, and then it is difficult to go further because of various reasons such as oxygen.”

Ingots of pure silicon are the basis of chips.

The higher the purity, the higher the yield rate of the chip will naturally be. So the moon became a center of cutting-edge manufacturing.

The two continued to move forward.

If I remember correctly, the previous machine is the famous YS-3D lithography machine.

It is about one story high and looks a bit like a large oven.

It's just that this guy was left out temporarily, because the "Earth Times" couldn't produce any chips at all. What kind of delicate structure is inside, Zhang Yuan has no way to see.

"Will it be broken in 3000 years?"

"No, you thought it was a TV set at home, and it would break if you don't use it for a long time?"

Zhao Qingfeng said with a smile: "We have already dealt with it beforehand. This is a cosmic space. There is no oxidation and corrosion of oxygen. Although there will be some quantum movements, it is still not a problem to preserve it for thousands of years."

That's true, in a vacuum environment coupled with ultra-low temperatures, almost anything can be preserved for a long, long time.

Even human and animal corpses can be preserved for a long time.

With the development of the aviation industry, the number of human corpses floating in the solar system has exceeded 50,000. Some of them returned safely, while some died without seeing their bodies, just quietly hiding in a certain corner of the solar system.

A few years ago, Zhang Yuan witnessed with his own eyes that a drone brought back the body of an astronaut.

He was shriveled like a mummy, surrounded by frost.

The fear still hasn't dissipated on his face, telling what happened at the last moment.

This is a worker named "Carter Bradenwald" who died in an accident during the construction of a space elevator a hundred years ago. After a hundred years, he finally returned to his roots and returned to the embrace of Mother Earth.

In the past, people raised their eyes to the Milky Way, and heroes were depicted in the constellations.

And now, we still look up, but the hero is cold.

If a civilization wants to develop, it will inevitably be accompanied by sacrifices. Zhang Yuan just hopes that the years will be quiet and peaceful. In the future, human beings will be able to endure such disasters less...
