Wandering Spaceship in Deep Space Chapter 78: Core industry

　　 Senior Brother Zhao smiled, "Insufficient heat dissipation capacity results in 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 two million tons of water. On average, each person has only 5 tons of water. And how much does the earth’s people have on average? 0.13 cubic kilometers, which is 1.3 Billion tons."

　　"One person owns fifty times as much as we combined!"

　　"You think, we have such a little water, our 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, drinking water needs to be distilled again. , How much energy does it need?"

　　 "Energy itself is not a problem. Nuclear fusion brings too much energy, but if the heat generated by these industries is not released 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 spacecraft were all ringed together.

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

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

　　He said: "So, we can't handle the heat that comes in, so can we simply throw it away by discharging substances?"

　　"It’s like this. When you arrive at Europa, you will replenish the material again... But after reaching Jupiter, there will be no more resources to replenish, and everyone will have to hibernate. Then the population will be drastically reduced and the heat dissipation capacity will be sufficient."

　　In the process of chatting like this, the rail car reached the first stop, which is the core industrial zone.

　　 This is a vacuum zone, and there is no gravity, and no external force can be used. It is extremely troublesome to move.

　　 For the convenience of the astronauts, electromagnetic generating devices are placed on the road. As long as it is aligned with the infrared probe on the spacesuit, after a signal is emitted, it will generate a certain amount of electromagnetic force, which will attract people.

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

　　 There are many workers working in the production room with a thin layer of glass.

　　 Zhang Yuan saw an old acquaintance—Ye Kaifu was focusing on something on an electronic screen, but he didn't 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 decided to train them in a way that saturates their work. It's always right to cultivate it anyway.

　　 The whole set of industrial processes was visited arrogantly, and there were not many machines in operation.

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

　　 Let me talk about the shortcomings first. First of all, the very conventional process of "extraction" cannot be achieved directly.

　　 To give a simple example, water and oil are placed in a bottle and shaken vigorously. Different solutes have different solubility in water and oil to separate and extract the solutes. This process is called "extraction". Realization on earth is very simple. But it takes a lot of effort in space. Because of weightlessness in space, water and oil cannot be separated.

　　Similar principles, rectification, absorption, precipitation, bubbling and other chemical processes cannot be simply realized in the gravity-free zone.

　　 However, because of the absence of gravity, the centrifuge is beginning to shine.

　　 As long as the centrifuge is used, it is equivalent to creating artificial gravity, rectification, absorption, precipitation, and bubbling.

　　 Also, the centrifuge in space is no longer disturbed by the gravitational environment, and can build larger land and separate purer substances.

　　 Senior Brother Zhao asked: "This super-gravity distillation machine can generate 500 g of gravity acceleration. How many times its separation speed is that of a distillation tower on earth? Do you know the formula?"

　　 Zhang Yuan frowned and thought for a minute.

What is the correlation formula of 　　 packing tower...

　　 "7.9 times!"

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

　　 However, I was only slightly surprised. For geniuses, there are naturally expectations for geniuses.

　　"Very good, the speed of distillation is proportional to the 1/3 power of the acceleration. As long as the rotation is faster, the speed of chemical purification is also faster."

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

　　Pure silicon ingots are the foundation of chips.

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

　　 The two continue to move forward.

　　If I remember correctly, this machine in front is the famous YS-3D lithography machine.

　　 It's about the height of a floor~IndoMTL.com~ It looks a bit like a large oven.

　　 It’s just that this guy was left out for the time being, because "Earth Age" could not produce any chips at all. Zhang Yuan couldn't see the subtle structure inside.

　　 "After 3000 years, will it be broken?"

　　 "No, you thought it was a TV set at home. It will break if it is not used for a long time?"

　　Zhao Qingfeng said with a smile: "We have already treated it specially beforehand. This is the universe. There is no oxidation and corrosion of oxygen. Although there will be some quantum motion, it is still not a problem to keep it for thousands of years."

　　 also said, vacuum environment coupled with ultra-low temperature, almost anything can be stored for a long, long time.

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

　　 With the development of the aviation industry, there are more than 50,000 human corpses floating in the solar system. Some returned safely, and some died without seeing them, just so quietly hidden in a corner of the solar system.

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

　　 He was shriveled like a mummy, surrounded by frost.

　　's face still doesn't fade away, telling what happened at the last moment.

　　 This is a worker named "Carter Bradenwald" who died in a crash while building a space elevator one hundred years ago. One hundred years later, the fallen leaves finally returned to their roots and returned to the embrace of Mother Earth.

　　In the past, people raised their eyes to the Milky Way, depicting heroes in the constellations.

　　 And now, we still look up, but the hero is already an icy drive.

　　If a civilization wants to develop, it will inevitably be accompanied by sacrifices. Zhang Yuan just hopes that the years will be quiet, and in the future, humans will be able to suffer less of such disasters...
