Chapter 863: [The terrorist military value of carbon nanotube wire]

"Space factory? That can cost a lot of money..." Liu Jianwei couldn't help but fill in the picture of the space factory. It would be best if the factory were to go to space. Some high-end cutting-edge industries are manufactured in space. The environment has unparalleled advantages.
The question is, how many trillions will it take to get it done? Don't even think about it without tens of trillions.
"Professor Liu, don't worry about financial issues. I have saved a lot of money over the years. If the budget is not enough, I can bring in some investors." Luo Sheng said with a smile, not to mention how relaxed his tone is.
Xindao: Isn’t it just money, the poor have money left~
Everyone: "..."
Everyone present was speechless.
Liu Jianwei once again tactically touched the mirror: "If we build a space factory and complete manufacturing in planetary orbit, this problem can be solved."
Not all the manufacturing of the ladder cable is carried out in the space factory, but the last few processes are completed in space, and most of the manufacturing processes still need to be completed from the ground.
The cable is not made of one piece, but a super-large ladder cable composed of thousands of carbon nanotube filaments of equal length, and the thickness of a single carbon nanowire is equivalent to 50% of the thickness of a human hair.
Roughly speaking, a single carbon nanotube filament material is first manufactured and then crimped independently, and the bundles are sealed. The mass of a single carbon nanotube is not much larger, and then it is transported to the planetary orbit by a carrier. The upper space factory will proceed to the next round of processes. At this time, the main process is to combine a large number of single carbon nanotubes to form the final ladder cable.
These major manufacturing processes greatly reduce the difficulty of manufacturing in the weightless space environment, and also improve the fault tolerance and efficiency. This is an advantage that no place on the surface of the planet has.
Luo Sheng looked at Liu Jianwei and asked, "How much natural graphite was used to make the raw materials of this rope?"
Liu Jianwei: "No less than 4 million tons of consumption."
The raw material of the ladder cable is mainly graphite, and the more expensive one is graphene. Natural graphite is quite cheap. The current market price is only about 3,000 yuan/ton.
A demand of 5 million tons is about 15 billion yuan.
Moreover, China happens to be the country with the largest natural graphite reserves in the world, with approximately 55 million tons of reserves. The global reserves are only 71 million tons, accounting for 77% of the world’s total. However, although the world’s reserves are the largest in the world, the domestic graphite industry has not developed. Not ideal, they are always raw material suppliers in the industrial chain for a long time.
It is worth mentioning that graphite raw materials are cheap, but the carbon nanotubes needed are finally manufactured through a complex process and become the final ladder cable. The comprehensive calculation of R&D and transportation costs will be more than 2000 times.
The transportation cost is not cheap, and it accounts for a large proportion. Even if the recoverable rocket greatly reduces the transportation cost of human beings to and from space, it is also a relative data. The actual absolute cost is not cheap, and it is still an astronomical figure.
It also means that the value of this rope has reached 30 trillion yuan, or about 4.36 trillion US dollars.
From the perspective of the overall structure of the sky tower base on the ground to the space station in outer space, this rope can be said to be the smallest module of the space structure, even the most inconspicuous, but it is the most expensive in the entire ladder structure. Module.
Compatible with the space factory’s orbital space station, a budget of 1 to 1.5 trillion US dollars is definitely enough. The ground tower base is relatively cheaper, and only needs a 200 billion US dollars budget.
However, this 4.36 trillion dollar rope carries the mission of mankind's substantial expansion to the entire solar system. Thinking about it this way, it is still very cost-effective.
"Mr. Luo, this is our result." Liu Jianwei took out an object that looked like a paper handover and gave it to Luo Sheng. The latter picked it up and took a look, and found the thread and pulled it out about a foot longer than normal. Her hair is half thin, and it is almost invisible to the naked eye.
There is a patch on the end of the thread, which can be pulled out by pinching the patch, otherwise you have to look for it for a long time.
Liu Jianwei looked at the things in his hand and introduced: "This is a complete single carbon nanotube. Its length is about 5 kilometers and its mass is only 21.211 grams."
Luo Sheng held the carbon nanofilament in his hand without saying a word. After a while, he suddenly asked Liu Jianwei: "Professor Liu, if this achievement of yours will be used in the military by the state, would you object to it?"
"Apply to the military?" Liu Jianwei was stunned and asked curiously: "This thing is not lethal, how can it be used in the military?"
Luo Sheng shook his head and said, "No, you are wrong. Not only can it exert unparalleled strategic and tactical value in the military, but its lethality is quite terrible. Professor Liu, have you read the science fiction novel "Three-Body", which describes it A plot called'Guzheng Project'."
Liu Jianwei shook his head. Where does he have time to read science fiction, a person who is obsessed with academic research every day and can't help himself. He can't wait to have 48 hours a day and he can't be too busy.
Luo Sheng simply said: "The so-called'Guzheng Project' plot describes the use of ultra-high-strength nanowire materials like this to connect the steel pillars on both sides of the Barnamar Canal to form a piano of death or an Internet cafe of death. When Evans, one of the leaders of the ETO organization, was ruthlessly cut when the cruise ship "Doomsday Judgment" passed through the canal...Professor Liu, you have created this powerful nanowire."
After that, Luo Sheng stared at Liu Jianwei, who was dumbfounded: "This...I never thought of such an application..."
Luo Sheng played with the roll of carbon nanowire in his hand, and said: "Mass production must be reported. I think it won’t take long for the military to send people over. From the military’s perspective, it’s bound to be obvious. Among them are huge military applications, so the first batch of nanowires manufactured is likely not to be used in the ladder cable first, but the military will place orders for priority applications and military."
You must know that the current international environment is becoming increasingly complex.
Hearing this, Liu Jianwei was silent for a moment before he replied: "It may not be a bad thing to be used for national defense construction. UU reading www.uukanshu.com I am not so pedantic and not so fraternal to the world. First of all, I am a Chinese. The second thing is that I made things that are not fake, but I can't be the master no matter how I use it. Anyway, it was made with your money, and you are the master.
When Luo Sheng heard him say this, he was relieved and said: "Professor Liu, I can't be the master, this master can only be done by the will of the country. So, instead of the military coming to the door to disrupt the ladder when the report is due. The project plan, it’s better to make a batch now, and I send it directly to the military."
Liu Jianwei nodded: "Alright, I will make arrangements here, but the budget may not be enough, you have to pay."
Luo Sheng laughed and said: "Money is never the biggest problem with me. I will inject 100 billion yuan into Star Arrow International. Don't worry about the money issue. You can use it in your department, and I will take care of it."
At the end, Luo Sheng got up, picked up the roll of nanowire on the table by the way, took it in his hand and added: "I'll leave everything here to you, I'll take this stuff."
After a few more conversations, he took the roll of carbon nanowires and left the room.
After leaving the building, a business car at the door had been waiting there for a long time. Luo Sheng took the vehicle back to the Science and Technology Complex.
At this moment, Luo Sheng sitting in the back seat was staring at the roll of carbon nanowire in his hand.
The military will definitely attach great importance to this thing, and will apply it 100% in the military. The "invisible net" composed of carbon nanowires can create a large area of ​​lore traps and is unparalleled in blocking important strategic waterways. Advantage.
Luo Sheng took out his mobile phone: "Xiao Na, contact me Yang Hongyi..."
