Great Power Technology.

Chapter 478
Relying on the information about pastoral organizations obtained from the Hermes organization, domestic pastoral organization activities were extinguished in a very short period of time, but this does not mean that this organization disappeared completely. On the contrary, most of them Also get good.

As for the reason?

In fact, in Qin Chuan's view, the reason is very simple.

All vested interests who have mastered the main resources of the society are potential pastoral organization members.

They can't bear the redistribution of the benefits they have already obtained because of the impact of several giant official projects, and they can't bear the ordinary people who are just "lower class" in their eyes, standing at the same height as them.

Therefore, when the time is right, or in other words, when the contradictions and confrontations between the two camps develop to a certain point, these people will naturally choose what they think is the last and most effective solution: transforming into a pastoral organization.

It is precisely because of this that Qin Chuan's quick response force has been set up as a standing force. Their struggle with the pastoral organization may not end for a long time.

While the quick response team was busy dealing with domestic pastoral organizations, on the other hand, the Huawu Institute had also started the assembly of large lasers and the first wall.

Ye Zhou stood on the edge of the construction site, looking at the equipment hoisted to the designated location from a distance, with a fascinated smile on his face.

"If the problems of the laser and the first wall are solved, we will basically break through all the technical problems of nuclear fusion in the experimental stage, right?"

Hearing his words, Qian Lixun nodded slightly and replied:
"It can be said that what we want to achieve now is the first plasma combustion, that is to say, not only to be satisfied with the output energy being greater than the input energy, but to ensure that the fusion fuel can achieve self-sustaining combustion."

"Judging from the current basic mathematical simulation, the Shenguang 5 project we are building now should be able to basically achieve this goal - which means that we are one step closer to large-scale practical use."

"However, from the experimental stage to the commercial stage, we actually still have a lot of technical problems to be solved, such as the divertor that is currently being developed in various countries."

The so-called divertor refers to a device in a nuclear fusion device that is used to discharge the particle flow and heat flow from the central plasma and the helium ash produced during the nuclear fusion reaction. Generally speaking, its function is probably It is equivalent to the furnace bottom of a common household coal stove.

One side of the divertor is burning plasma with a temperature as high as hundreds of millions of degrees, while the other side is ordinary materials other than the first wall. The temperature passing through the divertor must be reduced to less than one thousand degrees in milliseconds, which is The divertor is required to have a strong cooling function.

The current divertor design mainly adopts the combination of water cooling, air cooling and high heat-resistant target plate, which is more than enough to deal with laboratory-level nuclear fusion. If you want to realize commercialization, you must build on the existing basis go one step further.

But how to take this step, no one has given an answer.

The closed suction divertor is the most likely solution, but this device only stays on the paper. After nearly 10 years of development, until the tokamak device has matured, this divertor scheme has not yet been developed. Create even one.

Thinking of this, Ye Zhou nodded slightly, thinking to himself:

It seems that the design scheme of the divertor has to resort to the simulator.

However, the simulation of the "Little Sun" plot he is now doing has nothing to do with the divertor, but is applicable to the welding scheme of the nuclear fusion device. If he wants to point out the technology of the divertor, he does not know how many more simulations he needs to go through.

Therefore, he is not too impatient about it--after all, the divertor is almost the last threshold of commercialization. As long as the problem of the divertor is solved, the technical obstacles in the manufacture of artificial suns are in front of mankind. Only the energy export is left.

According to the current progress, it is not a big problem to build the first commercial nuclear fusion reactor in five years.

In this way, the speed of large-scale deployment of fusion reactors can be slightly accelerated.

The installation project is gradually coming to an end, and all the laser equipment is ready, but this does not mean that Shenguang 5 has reached the experimental conditions, and there is still a long period of debugging and preparation work waiting. In the cold start state, this The duration of some jobs can be as long as several months.

After the last bolt was tightened, Ye Zhou left the construction site with Qian Lixun and returned to the office.

After making tea as usual, the two chatted about some details of the follow-up test of Shenguang [-], and made some adjustments to the work arrangement. Ye Zhou finally breathed a sigh of relief after all the discussions were over.

Seeing his tired expression, Qian Lixun smiled and said:

"It seems that this project has squeezed you a lot. Why, is there a lot of psychological pressure?"

Ye Zhou smiled wryly and nodded. During this period of time, he had to deal with the actual work of the Shenguang [-] and Nantianmen projects during the day, and at night he had to enter the simulator for the next step of simulation. Occasionally, he had some free time and was dragged by Lin Ling. Discussing various issues related to the invasion of adjacent dimensions is really exhausting.

"The pressure can't be underestimated. After all, this is the first time in human history to face a deterministic and devastating disaster. It's not just me. In fact, everyone involved in the related work is under a lot of pressure."

"Including Lin Ling, that little girl, you know, although she doesn't have any specific work schedule now, she has a full schedule of experiments every day, and the experimental resources of CEPC have basically been drained by her --- it should be said, She's tougher than me."

Hearing Ye Zhou's words, Qian Lixun couldn't help but smile. He looked at Ye Zhou's face with great interest and said:

"You are called a little girl, how old are you? In my eyes, you are also a young man."

"Ham, it's just a title. She is also growing very fast. She almost collapsed a few months ago, but now, she feels that her fighting spirit has been fully aroused."

"After a while, I won't be able to call her little girl anymore—I'll have to call her Big Sister. I heard that people at CEPC are afraid of her."

"Afraid of her? Don't you? I've seen that child, and she's quite gentle."

"It's not that kind of fear, it's because she's afraid of her sudden death. Forget it, let's not talk about it--by the way, we've already talked here. I just want to ask you a question?"

Qian Lixun's expression became even more curious. He put down the teacup he had just picked up in his hand, and asked:
"what is the problem?"

Ye Zhou took a sip of water first, and after organizing his speech for 2 minutes, he said:
"Let me start with the background."

"It's still about adjacent dimensions. As you know, CEPC has been doing high-energy detonation experiments recently, trying to find evidence that can support string theory through high-precision experiments, because if string theory is experimentally confirmed, then we will be relatively Neighborhood research can take a big step forward."

"—Of course, this kind of attempt seems to be basically useless at present, but in the process, they discovered a problem."

"According to the viewpoint of string theory, we cannot explain why energy can be transferred between adjacent dimensions, but matter cannot be transferred."

"That's a big hole, you know, the big argument of those who are against string theory is that most of the logic of string theory is mathematical, it's the same thing as Laplace potential. "

"The latter can solve the problem of action at a distance almost perfectly mathematically, but it is not supported by any real-world experiments."

"You know, in China, due to the influence of Mr. Yang, the current research direction of the unified standard model and gravitational model still believes that we should invest more resources in work such as cosmological observations to Discover phenomena that go beyond the Standard Model and general relativity to guide us on more precise paths."

"And now, adjacent dimensions and quantum ghosts are typical phenomena that go beyond the standard model-these two phenomena can almost be said to negate all our previous research directions on grand unified theories."

"This also means that we have now entered a fork in the road."

"First of all, the general theory of relativity is absolutely correct after experimental verification, so there are only two possibilities before us: either the standard model is wrong, or the string theory is wrong."

"I know that you are not just an expert in applied technology, and your previous papers on string theory are also very professional. My question now is, if you look at it from your point of view, what do you think is the probability of which theory is wrong? bigger?"

After listening to Ye Zhou's words, Qian Lixun shook his head slightly, and replied:

"To be honest, those theoretical things are just a side job for me—or just a pastime. If you really want to know the details of this issue, you should ask Elder Yang directly."

"But, having said that, if you just want to ask me which is more error-prone, string theory or the Standard Model, I can give you the answer right now: it must be string theory."

"In the final analysis, string theory itself is just an attempt. It is not supported by actual experiments, so it is not surprising that it is overthrown at any time. Of course, even if it is really overthrown, we cannot deny that it has produced value."

"The current situation is that the physical phenomena we observe are obviously contrary to the superstring theory, and this violation is irreconcilable, so obviously, what we should do is not to try to establish a superstring theory based on this theory. Instead of tinkering with the previous ones, we started all over again.”

Hearing Qian Lixun's answer, Ye Zhou nodded solemnly.

"You mean, then, that we should abandon experimental exploration of string theory?"

"This only represents my personal opinion, and the specifics depend on the professionals who are really doing research in this area."

"You can provide my point of view to that little girl, and let her consider it in combination with everyone's opinions."

"understood."

The topic of pure theory ended here. Ye Zhou refilled Qian Lixun's cup with hot tea. The two chatted for a while. phone.

He was about to convey Qian Lixun's opinion to the other party, but Lin Ling spoke first:

"Gong Ye, I think the chances of using string theory to explain the problems we are encountering now are too slim."

"I don't want to spend resources on such experiments anymore. I plan to start a new one."
