Deep Space Fleet

师 Brother Zhao smiled, "Insufficient heat dissipation 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 held out a hand: "5 tons, the entire spaceship has more than 2 million tons of water, and each person has an average of only 5 tons of water. How much does the average human being have? 0.13 cubic kilometers, which is 130 million tons. "

"A person has fifty times our sum!"

"You think, we have so little water, the self-purification capacity is almost zero. Used water is scored into several levels for treatment, drinking water, industrial water, domestic sewage, etc. Among them, drinking water needs to be distilled again and it needs to be used. How much energy? "

"Energy itself is not a problem. The energy brought by nuclear fusion is much, but if the heat generated by these industries is not released in time, there will be a problem of thermal accumulation ... so that the heat dissipation capacity is completely insufficient."

"Oh, what I said." Zhang Yuan nodded, and he understood that the industry in the spaceship was looping around.

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

Any mistake in one link will cause the entire system to collapse. For a spacecraft, a relatively high fault tolerance rate must be maintained.

He said, "So, the heat that we can't handle at present, just throw it out by emitting substances?"

"It's like that, when I arrive at Europa, I will add another material ... but after I reach Jupiter, there will be no more resources to supplement, everyone will 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, it is extremely troublesome to move.

For the convenience of the astronauts, electromagnetic devices are placed on the road. As long as the infrared probe on the space suit is aligned, after emitting a signal, it will generate a certain electromagnetic force to **** people in.

Zhang Zhangyuan is no stranger to these devices, and soon grasped the knack for using them, flying across the corridor.

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

Zhang Zhangyuan saw an old acquaintance, Ye Kaifu, focusing on an electronic screen, but didn't run over to say hello.

In fact, there are not so many people in the production room, but in order to increase the proficiency of everyone, the management still decided to cultivate in a saturated work manner. It's always right to cultivate anyway.

The whole set of industrial processes was visited in an unobtrusive manner. Not many machines were used.

There are both advantages and disadvantages to the production of space industry inside the puppet spacecraft.

First talk about the disadvantages, the first is the very conventional process of "extraction", there is no way to achieve directly.

To give a simple example, water and oil are placed in a bottle and then shaken violently. The solubility of different solutes in water and oil is used to separate and extract the solutes. This process is called "extraction". Implementation on Earth is very simple. But in space, it is strenuous. In space, water and oil cannot be separated due to weightlessness.

Similar reasoning, chemical processes such as rectification, absorption, precipitation, bubbling, etc. can not be easily realized in the non-gravity zone.

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

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

Moreover, the centrifuge in space is no longer disturbed by the gravity environment, it can build a larger land, and purely separate more pure substances.

Brother Zhao asked: "This hypergravity rectifier can produce a gravity acceleration of 500 g, how many times is its separation speed faster than the distillation tower on earth? Do you know the formula?"

Zhang Yuan frowned, thinking for a minute.

什么 What is the correlation of packed tower ...

"7.9 times!"

青 Zhao Qingfeng was slightly surprised. I didn't expect this boy to know such an unpopular formula.

But I was only slightly surprised. Naturally, I had expectations for genius.

"Very good, the speed of rectification is proportional to the 1/3 power of acceleration. As long as the rotation speed is faster, the chemical purification speed 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, you can extract very high purity pure silicon ingots, with a purity of about 99.9999 ...%, about 15 9s, and the industry on the earth can only refine the purity of 11-12 9s, and then for various reasons such as oxygen, it is difficult to go further. "

Pure silicon ingot is the basis of the chip.

The higher the purity, the higher the yield of the chip. So the moon became the center of cutting-edge manufacturing.

The two continued to move forward.

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

It's about one floor high ~ www.readwn.com ~ looks a bit like a large oven.

However, this guy has been left out for a while because the "Earth Age" can't produce any chips at all. What kind of subtle structure is inside, Zhang Yuan can't see it.

"Will it be broken after 3000 years?"

不会 "No, do you think the TV set at home will break if it is not used for a long time?"

青 Zhao Qingfeng said with a smile: "We have dealt with it in advance. This is cosmic space. There is no oxidative corrosion of oxygen. Although there will be some quantum motion, it is not a problem to keep it for thousands of years."

What I said is that the vacuum environment combined with ultra-low temperature can save almost anything for a long time.

Even the carcasses of humans and animals can be preserved for a long time.

With the development of the aviation industry, more than 50,000 human corpses have been floating in the solar system. Some have returned safely, and some have not seen the corpses, so they have hidden in a certain corner of the solar system so quietly.

几年 A few years ago, Zhang Yuan once witnessed that a drone brought back the body of an astronaut.

He was as dry as a mummy, surrounded by frost.

There was still no panic in her face, telling her last-minute encounter.

This is a worker who died in the construction of a space elevator a hundred years ago, named "Carter Bradenwald". One hundred years later, he finally returned to the embrace of Mother Earth.

In the past, people looked up at the galaxy, depicting heroes in the constellations.

现在 Now, we are still looking up, but the hero is a cold drive.

If a civilization wants to develop, it will inevitably be accompanied by sacrifice. Zhang Yuan just hopes that the years will be quiet. In the future, human beings can experience less such disasters ...
