"Space factory? That costs a lot of money..." Liu Jianwei couldn't help but imagine the picture of the space factory. It would be best if he brought the factory into space like a factory. Some high-end and cutting-edge industrial manufacturing has unparalleled advantages in space environments.

The question is, how many trillions of dollars does it take to make it happen? Don’t even think about it without tens of trillions of dollars.

"Do not worry about funding issues Professor Liu. I have saved a lot of money over the years. If the budget is not enough, I can also attract some investors." Luo Sheng said with a smile, not to mention how relaxed that tone was.

I thought to myself: Isn’t it just money, I am the poor and I have only money left~

Everyone: "..."

Everyone present was speechless.

Liu Jianwei once again tactical and scrutinized the mirror: "If a space factory is established and manufacturing is completed in planetary orbit, this problem can be solved."

The manufacturing of ladder cables is not all carried out in space factories, 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 a single piece, but a super-large ladder cable consisting of thousands of carbon nanotube wires of the same length. The thickness of a single carbon nanowire is equivalent to 50% of the hair.

Generally speaking, the single carbon nanotube wire material is first made and curled independently, and packed bundles are stored. The single carbon nanotubes are not much more mass. Then they are transported to the space factory in planetary orbit through vehicles for the next round of process. 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 have greatly reduced the manufacturing difficulty in a weightless space environment, and also improved the error tolerance and efficiency, which is an advantage that no location on the surface of the planet has.

Luo Sheng looked at Liu Jianwei and asked, "How much natural graphite will it cost to create the raw materials for this rope?"

Liu Jianwei: "The consumption is not less than 4 million tons."

The raw material of ladder cable is mainly graphite, and the most expensive one is graphene. Natural graphite is quite cheap. The current market price is only about 3,000 yuan/ton.

The demand for 5 million tons is only about 15 billion yuan.

Moreover, China happens to be the country with the largest natural graphite reserves in the world, with a reserve of about 55 million tons, and the global reserves are only 71 million tons, accounting for 77% of the world. However, although the reserves are the world's largest, the development of the domestic graphite industry is not ideal, and it has been a raw material supplier in the industrial chain for a long time.

It is worth mentioning that graphite raw materials are cheap, but they are eventually made into the required carbon nanotubes through complex processes and become the final ladder cable. The comprehensive calculation of R&D and transportation costs will be more than 2,000 times.

Among them, the transportation cost is not cheap, and it accounts for a considerable proportion. Even if the recyclable rockets greatly reduce the transportation cost of humans to and from space, it is relatively 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.

Judging from the overall structure of the space ladder from the base of the sky tower on the ground to the space station in outer space, this rope can be said to be the module with the smallest space structure, or even the most inconspicuous one, but it is the most expensive module in the entire ladder structure.

The budget of the orbital space station that is compatible with the space factory is definitely enough to hold up to $1 to $1.5 trillion. The sky tower base on the ground is relatively cheaper, and it only costs $200 billion.

However, this $4.36 trillion rope carries the mission of human beings to expand significantly into the entire solar system. It is still very cost-effective to think about it this way.

"Mr. Luo, this is our result." Liu Jianwei took out an object similar to the hand-in-hand and gave it to Luo Sheng. The latter picked it up and looked at it. He found the thread and pulled it out and stretched it out about a foot long, which was half thinner than a normal person's hair, and it was almost invisible to the naked eye.

There is a patch sticking at the end of the thread. You can pull it 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 nanopipe, with a length of about 5 kilometers and a mass of only 21.211 grams."

Luo Sheng held the carbon nanowire in his hand without saying a word. After a while, he suddenly asked Liu Jianwei: "Professor Liu, if your achievements will be used by the state for military purposes, you would not object, right?"

"Apply to military?" Liu Jianwei was stunned for a moment and asked curiously: "This thing has no lethality, how can it be used in military affairs?"

Luo Sheng shook his head and said, "No, you are wrong. It can not only exert unparalleled strategic and tactical value in military affairs, but also has a terrible lethality. Professor Liu, have you seen the science fiction "Three-Body Problem", which describes a plot called the "Guzheng Project"?"

Liu Jianwei shook his head. He didn't have time to watch science fiction. He was a person who was addicted to academic research every day and could not extricate himself. He wished he could have 48 hours a day, but he couldn't even get busy.

Luo Sheng said simply: "The so-called 'Guzheng Plan' plot describes the use of ultra-high-strength nanowire materials similar to this kind of ultra-high-strength nanowire material to connect the steel columns on both sides of the Panama Canal to form a piano of death or Internet cafe of death. When Evans, one of the leaders of the ETO organization, passed through the canal, he was ruthlessly cut... Professor Liu, you have already created such powerful nanowires."

After saying that, Luo Sheng looked at Liu Jianwei, who was stunned and stunned: "This... I have never thought of such an application..."

Luo Sheng played with the roll of carbon nanowires in his hand and said, "Massive mass production must be reported. I think it will take a short time for the military to send people here. From the perspective of the military, we will inevitably see the huge military application value at a glance. Therefore, the first batch of nanowires manufactured are likely not used first for ladder cables, but for the military to place an order, priority application and military."

You should know that the current international environment is becoming increasingly complex.

Upon hearing this, Liu Jianwei was silent for a moment before replying: "It may not be a bad thing to be used in national defense construction. I am not that pedantic and not so fraternal in the world. First of all, I am a Chinese, and secondly, I am a Chinese, but I am not fake, but I can't make the decision no matter how I use it. Anyway, it's made with your money, and you'll make the decision."

Luo Sheng felt relieved when he heard him say this and said, "Professor Liu, I can't make the decision. This master can only be done by the will of the country. Let's do this. Instead of reporting to the military to come to disrupt the plan of the ladder project, it is better to make a batch of people now and I will send it directly to the military."

Liu Jianwei nodded: "Okay, I will make arrangements here, but the budget may not be enough, you have to send money."

Luo Sheng laughed and said, "Money is never the biggest problem for me. I will inject 100 billion yuan into Xingjian International. Don't worry about money. Your department will use it casually, and I will take care of it."

Finally, Luo Sheng stood up, picked up the roll of nanowires on the table, and took them in his hand and added: "I'll leave the matter here to you, I'll take this thing."

After a few more talks, I left the room with the roll of carbon nanofilaments.

After leaving the building, a business car at the entrance had parked there and waited for a long time. Luo Sheng took the vehicle back to the Science and Technology Complex.

At this moment, Luo Sheng, who was 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 use it 100% to the military. The "invisible web" composed of carbon nanowires can create a huge area of ​​killing traps and have an unparalleled advantage in blocking important strategic waterways.

Luo Sheng took out his cell phone: "Xiao Na, contact Yang Hongyi..."
