Gate of Technology

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 around and walked out, saying at the same time: The tender this afternoon Yes, I will choose a suitable construction company.

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 the back of Zheng Jia leaving, Cheng Yuan sat on the chair and smiled bitterly. He suddenly felt that the boss was not so easy to be.

It seems that I will learn more about this in the future. Cheng Yuan sighed with emotion, and then refocused on the theory of controllable nuclear fusion.

The process of nuclear fusion is very simple. A deuterium (read: knife) nucleus is accelerated with an accelerator and then collided with a tritium (read: Chuan) nucleus at a very high speed, and the two nuclei fuse to form a new nucleus— —Helium plus a free neutron, releasing 17.6 megaelectron volts of energy in the process.

This process is also the principle that the sun continues to emit light and heat for 4.5 billion years.

At present, the research direction of nuclear fusion all over the world is focused on magnetic confinement. The principle of this method is based on the positively charged characteristics of atomic nuclei. If our magnetic field is strong enough, the atomic nucleus cannot escape, as long as a ring-shaped magnetic field is established. , then the nucleus can only move in a spiral shape along the direction of the magnetic field lines, out of the range of the magnetic field, and at a distance outside the annular magnetic field, build a large heat exchange device, and then use the already very Familiar method to convert thermal energy into electricity.

But Cheng Yuan owns a completely different fusion reactor, and his theory comes from the movie Iron Man. In the movie, the fusion reaction is carried out by adsorbing hydrogen through palladium, which is more advanced!

Because the first step of nuclear fusion researched all over the world is to heat the mixture as a reactant to a plasma state, that is, the temperature is high enough to make the electrons free from the bondage 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 that's not enough!

The repulsive force between the nuclei with the same positive charge, the nuclei need to run at an extremely fast speed, and the easiest way to get this speed is to continue to heat up, so that the random collision of the nuclei reaches a crazy level. Achieving this operating state requires hundreds of millions of degrees Celsius.

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

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

There is only one problem with such an approach, where do we put this hundreds of millions of degrees Celsius reactor?

So far, humans have not created any chemical structure that can withstand 10,000 degrees Celsius, let alone hundreds of millions of degrees Celsius. That's the only reason why, 50 years after the hammer-and-bull ** has been made, humans haven't been able to efficiently harvest energy from nuclear fusion.

Of course, the fact that human beings can become the masters of the earth shows that their intelligence is much smarter than other creatures, and the problems that cannot be solved in chemical structure are turned to physics by him. This is how magnetic confinement fusion occurs.

A well-known method currently known is the tokamak type magnetic field confinement method. It uses a strong magnetic field generated by a strong electric current to confine the plasma in a small area to achieve nuclear fusion.

While it was close to success under laboratory conditions, it didn't last long.

Technically speaking, there will be a turbulent phenomenon in the process of plasma movement, and the movement of disordered and irregular particles is unmeasurable. However, in the high temperature and high density plasma of tokamak, there will be a lot of instability. The root probe goes into the center of the plasma, and that immediately triggers instability and the entire plasma falls apart.

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

The maximum stable magnetic field that humans can achieve now is about the order of 10T. The electromagnet that generates such a large magnetic field must require a huge current, and the huge current will heat up, and after it heats up, it will turn The material is burned by itself, so the largest tokamak project ITER being built now is the method of superconducting coils, which indeed solves the problem of heat generation, but if the coils want to maintain superconductivity, they need extremely low temperature and liquid helium. soak.

So everyone can imagine such a scene 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 several Kelvin! The difficulty of engineering realization can be imagined.

The last difficulty is economic. To make such a large superconducting magnet, it will definitely cost hundreds of billions of dollars! It's dollars!

Therefore, the largest tokamak project, ITER, is not done by one country at all, but is jointly funded and cooperated by 7 countries. Once the budget is exceeded, this number will increase without an upper limit, which may be trillions of dollars. It could be ten trillion or a trillion dollars.

This process depends on the wisdom and creativity of researchers.

Compared with them, the theory mastered by Cheng Yuan is a complete technology that can be implemented concretely.

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

However, writing a thesis is not so simple. What is required is not only one's own findings, but also some previous relevant literature to be verified. A qualified paper needs a lot of literature for verification, but Cheng Yuan doesn't know this. He is now sitting in front of the computer, weaving the knowledge in his mind into words, and then inputting it into the computer.

...

In the capital of China, in a secret conference room of the Ministry of National Defense, Colonel Yang Qiaoyuan was wearing a dark green military uniform, and he was reporting to his boss with a serious face. Sir, regarding the intelligent core, Cheng Yuan has no intention of exchanging at the moment.

Currently? Yang Qiaoyuan's boss was a middle-aged man in his fifties with a resolute face. The man wore a military uniform and had a star on his shoulders. He was not dissatisfied with Yang Qiaoyuan's words, but looked at Yang Qiaoyuan curiously and said, What do you mean, that little guy Cheng Yuan will meet in the future?

Yes. Yang Qiaoyuan nodded and said, Although I don't know why he had to wait for a while, this is his answer.

The man smiled slightly and said, This little guy is covering himself quite tightly. Since people don't want to, forget it. I will report this matter. You go down first. The man waved to Yang Qiaoyuan.

But Yang Qiaoyuan didn't go out. He said loudly, Boss, although Cheng Yuan didn't agree to our request, 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 great interest.

Yang Qiaoyuan paused for a moment and said solemnly: The chief, it's graphene. He said that he has a brand new graphene preparation technology in his hands, which is more powerful than any preparation technology today, but he did not give me any A written description.

Hearing the words, the man 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 top responds. The man was quite emotional, and at the same time He is also more attentive to Cheng Yuan, and only then did he create an intelligent robot. Now it is all graphene. Will it enter the energy industry in a while?

The man laughed at his sudden whim.

But the man didn't know that his whim just happened to guess what Zhong Chengyuan was planning, because he had already started writing a paper on controllable nuclear fusion.
