Cthulhu Gonfalon Chapter 55:

"Think about it for yourself, I don't expect you to be so wise in the future, but at least you won't make the same mistake again." Zheng Jia took a deep look at Cheng Yuan, then turned and walked out, and said at the same time:" I will choose a suitable construction company for the bidding meeting in the afternoon."

For Zheng Jia, it is normal for Cheng Yuan to have shortcomings, otherwise it would be too scary because it is too unrealistic.

Looking at Zheng Jia's departure, Cheng Yuan sat on the chair with a wry smile, and suddenly he felt that the boss was not so good.

"It seems that we need to learn more about this in the future." Cheng Yuan sighed, and then refocused his attention on the theory of controlled nuclear fusion.

The process of nuclear fusion is very simple, that is, a deuterium (read: knife) nucleus is accelerated by an accelerator and collides with a tritium (read: Sichuan) nucleus at a very high speed. The two nuclei fuse to form a new The nucleus of the atom-helium plus a free neutron, released 17.6 meV of energy in the process.

This process is also the principle by which the sun continues to glow and heat for 4.5 billion years.

At present, the research direction of nuclear fusion around the world is focused on magnetic confinement. The principle of this method is based on the positively charged nature of atomic nuclei. If our magnetic field is strong enough, the atomic nucleus will not be able to escape. With a toroidal magnetic field, the nucleus can only move in a spiral along the direction of the magnetic line of force, and cannot run out of the magnetic field. At a little distance outside the toroidal magnetic field, a large heat exchange device can be built and then used. The method that mankind is already familiar with is to convert thermal energy into electrical energy.

But the nuclear fusion reactor owned by Cheng Yuan is completely different. His theory comes from the movie Iron Man. In the movie, the fusion reaction is carried out by absorbing hydrogen with palladium, which is even more advanced!

Because the first step of nuclear fusion researched around the world is that the mixed gas as a reactant must be heated to a plasma state, that is, the temperature is high enough to make the electrons free from the **** of the nucleus, and the nucleus can move freely.

At this time, it is possible to make direct contact between the nuclei. At this time, a temperature of about 100,000 degrees Celsius is required.

And this is not enough!

The repulsive force between the nuclei that are also positively charged. The nuclei need to move at a very fast speed. The easiest way to get this speed is to continue heating, so that the random collision of the nuclei reaches a crazy level. For the nucleus to reach this operating state, a temperature of hundreds of millions of degrees Celsius is required.

The last step is to collide the tritium nucleus and deuterium nucleus at a great speed without any cover, producing new helium nuclei and new neutrons, releasing huge energy. After a period of continuous input, when the reaction body no longer needs external energy heating, the temperature of nuclear fusion is enough to make the nuclei continue to fusion.

In this process, helium nuclei and neutrons will be eliminated in time, and the new mixture of tritium and deuterium will be input into the reaction body, nuclear fusion can continue, and a small part of the energy produced will remain in the reaction body to maintain Most of the chain reaction can be exported and used as an energy source.

There is only one problem with such a method. Where do we put this reaction body that is as high as hundreds of millions of degrees Celsius?

So far, humans have not created any chemical structure that can withstand 10,000 degrees Celsius, let alone hundreds of millions of degrees Celsius. This is the only reason why human beings have not been able to effectively obtain energy from nuclear fusion after 50 years of the creation of a mallet.

Of course, human beings can become the master of the earth, which shows that their intelligence is much smarter than other creatures. He turned to the physical aspect for the problems that cannot be solved in chemical structure. This is how magnetic confinement nuclear fusion is produced.

The well-known method currently known is the "tokamak" type magnetic field confinement method. It uses a strong magnetic field generated by a strong current to confine the plasma in a small area to achieve nuclear fusion. Although it is close to success under laboratory conditions, the continuous process is not long.

Technically speaking, there will be a turbulence phenomenon during the plasma movement. The disordered and irregular particle movement is unpredictable. In the Tokamak, the high temperature and high density plasma will have a lot of instability. If Insert a probe into the center of the plasma, and it will immediately trigger instability and the entire plasma will fall apart.

In terms of engineering, if we want to achieve the ignition conditions for fusion, then in engineering we need to generate a strong enough magnetic field in a large enough volume, about 10T.

Now the maximum stable magnetic field that humans can achieve is about the order of 10T. An electromagnet that generates such a large magnetic field must require a huge current, and the huge current will generate heat. It will burn the material by itself, so the largest tokamak project ITER currently under construction is the superconducting coil method. This indeed solves the heating problem, but the coil needs to be extremely low-temperature to maintain superconductivity. Immerse in liquid helium.

So you can imagine a scene like "In a room, the internal temperature is an ultra-high temperature of 100 million degrees Celsius, and the surface temperature is an ultra-low temperature of a few Kelvin!" The difficulty of engineering realization can be imagined.

The difficulty in the last aspect is economic. It would cost hundreds of billions of dollars to make such a large superconducting electromagnet! It's US dollars!

So now the largest tokamak project ITER is not one country at all, but seven countries are working together to contribute money and cooperation. Once the budget is exceeded, the number will increase without limit, which may be tens of thousands. Billion US dollars, it may also be ten trillion or hundreds of billions of dollars.

This process depends on the wisdom and creativity of scientific researchers.

Compared with them, the theory in Cheng Yuan's hands is a complete and practical technology.

Cheng Yuan can imagine that once his controllable nuclear fusion theory is released, it will bring a world-class earthquake.

However, writing an essay is not so simple. What you need is not only your own discovery, but also corroboration with some related literature in the past. A qualified paper needs a lot of literature to verify, but Cheng Yuan is not clear about this. He now sits in front of the computer and knits the knowledge in his mind into words, and then enters it into the computer.

……

In the capital of China, in a secret meeting room of the Ministry of National Defense, Colonel Yang Qiaoyuan, wearing a dark green uniform, is reporting to his boss with a serious face. "Chief, with regard to the intelligent core, Cheng Yuan currently has no intention to exchange."

"Currently?" Yang Qiaoyuan's boss is a middle-aged man who is about fifty years old and has a strong face. The man wears a military uniform with a star on his shoulder. He didn't feel dissatisfied because of Yang Qiaoyuan's words, but looked at Yang Qiaoyuan curiously and said: "You mean, that little guy Cheng Yuan will be in the future?"

"Yes." Yang Qiaoyuan nodded: "Although it is not clear why he waited for a while, this is his answer."

The man smiled slightly and said: "This little guy covered it very tightly. If they don't want to, let's forget it, I will report this matter, so you can go down first." The man waved his hand to Yang Qiaoyuan.

But Yang Qiaoyuan did not go out~IndoMTL.com~ He said loudly: "The chief, although Cheng Yuan did not agree to our request, but he came up with something else and wanted to cooperate with us."

"What?" The man's eyes flashed, and he looked at Yang Qiaoyuan with interest.

Yang Qiaoyuan paused and said in a deep voice: "The chief is graphene. He said that he has a brand-new graphene preparation technology in his hand, which is more powerful than any current preparation technology, but he does not Give me any kind of written explanation."

The man heard the words, pondered for a moment, and said to Yang Qiaoyuan: "Don't publicize this matter. I will report the situation here. The specific situation depends on how the above reacts." The man was quite quite. He sighed, and at the same time he became more concerned about Cheng Yuan. Only then did he create an intelligent robot, and now the entire graphene, will it enter the energy industry in a while?

The man was amused by his sudden whim.

But the man didn't know, his whim was just right to guess Cheng Yuan's plan, because he had already started writing a thesis on controlled nuclear fusion.
