Chapter 55:

"Think about it yourself, I don't expect how wise you will be 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 away and said, "In the afternoon tender Yes, I will choose a suitable construction company. "
郑 For Zheng Jia, it is normal for Cheng Yuan to have shortcomings, otherwise it is too scary because it is too unrealistic.
Looking at the back of Zheng Jia's departure, Cheng Yuan sat in a chair with a bitter 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 on the theory of controlled nuclear fusion.
The process of nuclear fusion is very simple. After accelerating a deuterium (read: knife) nucleus with an accelerator, it collides with a tritium (read: Sichuan) nucleus at a very high speed. The two nucleuses merge to form a new nucleus— -Helium plus a free neutron releases 17.6 megaelectron volts in the process.
This process is also the principle that the sun emits heat for 4.5 billion years.
At present, the research directions of nuclear fusion all over the world are focused on magnetic constraints. The principle of this method is based on the positively charged characteristics of the nucleus. If our magnetic field is strong enough, the nucleus will not run out, as long as a ring-shaped magnetic field is established. , Then the nucleus can only move in the direction of the magnetic field lines, along the spiral, can not run out of the range of the magnetic field, and a little distance outside the ring magnetic field, then build a large heat exchange device, and then use humans already very A familiar method to convert thermal energy into electricity.
But Cheng Yuan's nuclear fusion reactor is completely different. His theory comes from the movie Iron Man. In the movie, the fusion reaction is carried out through the adsorption of hydrogen by palladium, which is more advanced!
Because the first step of nuclear fusion researched around the world is to heat the mixture as a reactant to a plasma state, that is, the temperature is high enough to allow the electrons to escape from the nucleus of the nucleus, and the nucleus can move freely.
At this time, it is possible to make direct contact with the nucleus. At this time, a temperature of about 100,000 degrees Celsius is required.
And this is not enough!
Similarly, the repulsive force between positively charged nuclei needs to run at extremely fast speeds. The easiest way to get this speed is to keep warming to make the random collision of nuclei reach a crazy level. To make the nuclei Reaching this operating state requires temperatures in the hundreds of millions of degrees Celsius.
The final step of thorium is to collide the nucleus of tritium with the deuterium's nucleus at an extremely high speed without any cover, generating new helium nuclei and new neutrons, releasing huge energy. After a period of continuous input, the temperature of nuclear fusion is sufficient for the nuclear fusion to continue to occur when the reaction body does not need to be heated by external energy.
In this process, the helium nucleus and neutrons will be eliminated in time, the new mixed gas of tritium and deuterium will be input to the reaction body, and nuclear fusion will continue. A small part of the energy generated will remain in the reaction body to maintain the chain reaction. Most can be exported and used as energy.
There is only one problem with this method. Where do we put this reaction body at a temperature of 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 50 years after a single hammer sale, humans have not been able to effectively obtain energy from nuclear fusion.
Of course, human beings can become the masters of the earth, indicating that their intelligence is much smarter than other living things, and he has turned to the physical aspect for problems that cannot be solved on the chemical structure. This is how magnetically constrained nuclear fusion occurs.
A well-known method is the "Tokamak" type magnetic field constraint method. It uses a strong magnetic field generated by a strong current to confine the plasma to a small range to achieve nuclear fusion. Although near success in laboratory conditions, the ongoing process is not long.
Technically, a turbulent phenomenon occurs during the movement of the plasma. The disordered and irregular particle movement is unmeasurable, and in the Tokamak high temperature and high density plasma, there will be a lot of instability. A probe enters the center of the plasma, and that instability is immediately excited, so the entire plasma will fall apart.
工程 In terms of engineering, if we want to achieve the ignition conditions of fusion, then in engineering we need to generate a sufficiently strong magnetic field in a sufficiently large volume, about 10T.
Now the maximum stable magnetic field that humans can achieve 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 generate heat. The material burns itself, so the largest tokamak project ITER currently under construction is the superconducting coil method. This really solves the problem of heat generation, but if the coil is to maintain superconductivity, it needs extremely low temperature and liquid helium. soak.
So everyone can imagine such a scene "in a room, the internal temperature is 100 million degrees Celsius ultra-high temperature, and the surface temperature is a few Kelvin ultra-low temperature!" Engineering difficulty can be imagined.
The last difficulty is economic. Making such a large superconducting magnet will cost hundreds of billions! It's dollars!
So now the largest Tokamak project ITER is not done by one country at all, but by 7 countries to cooperate and cooperate. Once it exceeds the budget, this number will increase without limit, which may be trillions of dollars. It could be ten trillion or trillion dollars.
This process depends on the wisdom and creativity of scientific researchers.
Compared with them, Cheng Yuan's theory is a complete and practical technology.
Cheng Chengyuan can imagine that once the theory of controlled fusion in his hands is released, it will bring a world-class earthquake.
However, writing a dissertation is not so simple. It requires not only your own findings, but also confirmation with some related literature in the past. A qualified paper requires a large amount of literature to verify, but Cheng is far from clear. He is now sitting in front of the computer and weaving the knowledge in his mind into words, and then typing it into the computer.
Uh ...
In the secret meeting room of the Ministry of National Defense in the capital of Huaxia, Colonel Yang Qiaoyuan, wearing dark green uniforms, reported seriously to his boss. "Head, regarding the intelligent core, Cheng Yuan currently has no intention to exchange."
"Currently?" Yang Qiaoyuan's boss was a fierce-looking middle-aged man, about fifty years old ~ EbookFREE.me ~. The man wore a star on his shoulder in military uniform. Instead of being dissatisfied with Yang Qiaoyuan's words, he looked at Yang Qiaoyuan curiously and said, "Do you mean, Cheng Yuan's little guy will be stunned in the future?"
"Yes." Yang Qiaoyuan nodded. "Although it is not clear why he has to wait for some time, this is his answer."
The man with a slight smile said: "This little guy is quite tightly covered. Since people don't want to let it go, I will report it, you go down first." The man waved at Yang Qiaoyuan.
However, Yang Qiaoyuan did not go out, he cried out: "Head, although Cheng Yuan did not agree to our request, he took out another thing and wanted to cooperate with us."
"What?" The man's eyes flashed and he looked at Yang Qiaoyuan with interest.
Yang Qiaoyuan paused and Shen said: "The chief is graphene. He said that he has a brand-new graphene preparation technology in his hand, which is more powerful than any kind of preparation technology today, but he did not give me any A written description. "
The man heard the words and groaned for a while, and said to Yang Qiaoyuan, "You don't have to preach this. I will report the situation here. The specific situation depends on how you react." The man was quite emotional, meanwhile, He is even more interested in Cheng Yuan, and this is how he built up an intelligent robot. Now the whole graphene, is it going to enter the energy industry in a little while?
The man was amused at his sudden whim.
However, the man didn't know that his sudden imagination happened to guess Zhong Chengyuan's plan, because he has begun to write a controlled fusion fusion paper ~ EbookFREE.me ~ Welcome the book readers to read, the latest, fastest, most Fire serial works are all in ~ EbookFREE.me ~ Mobile users please read.
