Senior Brother Zhao smiled, "The heat dissipation ability is insufficient, which leads to the sewage treatment ability. Do you know how much water each of us has on average?"

Zhang Yuan shook his head.

Zhao Qingfeng stretched out his hand: "5 tons, the entire spacecraft has only more than two million tons of water, and on average, each person has only 5 tons of water. How many people on earth have on average? 0.13 cubic kilometers, that is, 130 million tons."

"What a person has is fifty times our total!"

"You think, our self-purification ability is almost zero. The used water is divided into several levels for treatment, such as drinking water, industrial water, domestic sewage, etc. Among them, drinking water needs to be redistilled, how much energy is needed?"

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

"Oh, what I said." Zhang Yuan nodded. He understood that the industry in the spacecraft was connected one by one.

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

Any error in any link will cause the entire system to collapse. A spacecraft must retain a very high error tolerance rate.

He said: "So, can the heat that we can't handle at the moment be thrown out by emitting substances?"

"It's like this. When you arrive at Europa, you will have to hibernate the substance again... But after you arrive at Jupiter, you will no longer have resources to replenish it, and you will have to hibernate. By then, the population will drop sharply and the heat dissipation capacity will be completely sufficient."

During the chat like this, the rail car arrived at its first stop, which is the core industrial area.

This is a vacuum zone, and with no gravity, no external force is needed, so it is extremely troublesome to move.

For the convenience of astronauts' movements, electromagnetic generators are placed on the road. As long as the infrared probe on the spacesuit is aimed at and a signal is emitted, it will generate a certain amount of electromagnetic force and suck people over.

Zhang Yuan was no stranger to these devices, and soon mastered the tricks of using them, flying across the corridor.

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

Zhang Yuan saw an old acquaintance, Ye Kaifu, focusing on something at an electronic screen, but he did not run over to say hello.

In fact, there are not so many people in the production room, but in order to increase everyone's proficiency, the management still decided to train it in a saturated way. Anyway, it is always correct to train it.

After a brief visit to the entire industrial process, there are not many machines that start.

The space industrial production in the spacecraft has both advantages and disadvantages.

Let’s talk about the shortcomings first. First, the very conventional process of “extraction” cannot be directly implemented.

To give a simple example, water and oil are placed in a bottle and shaken violently. Using different solutes in water and oil, separate and extract the solutes. This process is called "extraction". It is very simple to implement on Earth. But it is difficult to be in space. In space, water and oil cannot be separated due to weight loss.

Similar principles are: chemical processes such as distillation, absorption, precipitation, and bubble cannot be simply implemented in the gravity-free zone.

However, because of the lack of gravity, the centrifuge began to shine.

As long as you use a centrifuge, it is equivalent to creating artificial gravity, distillation, absorption, precipitation, and bubbles.

Moreover, centrifuges in space are no longer disturbed by the gravity environment, and can create larger ground and purely separate more pure substances.

Senior Brother Zhao asked: "This supergravity distillation machine can generate a gravity acceleration of 500 g. Its separation speed is how many times that of the distillation tower on Earth? Do you know the formula?"

Zhang Yuan frowned and thought for a minute.

What is the correlation form of the packing tower...

“7.9 times!”

Zhao Qingfeng was slightly surprised. He didn't expect that this kid even knew such an unpopular formula.

But I was just a little surprised. I naturally had expectations for geniuses.

"It's very good. The distillation speed is proportional to 1/3 of the acceleration. As long as the rotation ground is faster, the faster the chemical purification speed will be."

"On our moon, there is a very complete silicon purification industry, but unfortunately you can't see it now. Through repeated acidification and distillation, you can extract extremely high-purity pure silicon ingots, with a purity of about 99.9999...%, about 15 9s. The industry on earth can only extract 11-12 9s, and then it is difficult to further improve due to various reasons such as oxygen."

Pure silicon ingots are the basis of chips.

The higher the purity, the higher the yield rate of the chip will naturally be. Therefore, the moon has become the center of cutting-edge manufacturing.

The two continued to move forward.

If you remember correctly, the machine in front is the famous ys-3d lithography machine.

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

However, this guy was temporarily neglected because the "Earth Age" could not produce any chips at all. Zhang Yuan could not see what exquisite structure there was inside.

“Will it be broken after 3000 years?”

"No, do you think it's a TV set at home and it will break if you don't need it for a long time?"

Zhao Qingfeng smiled and said, "We have dealt with it in advance. This is the universe. There is no oxidation and corrosion of oxygen. Although there will be some quantum motion, it will still be no problem to retain it for thousands of years."

As it is said, vacuum environment and ultra-low temperatures can be stored for a long time.

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

With the development of the aviation industry, more than 50,000 human corpses floating in the solar system have been exceeded 50,000. Some have returned safely, while others have not seen any corpses. They are just hiding quietly in a 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 disappeared on his face, telling the last moment of his experience.

This is a worker who died in the crash while building a space elevator a hundred years ago. He was named "Carter Bledenwald". A hundred years later, he finally returned to his roots and returned to the embrace of Mother Earth.

In the past, people looked at the Milky Way and portrayed heroes in their zodiac signs.

And now, we still look up to it, but the hero is already a cold drive.
