"Flower growers should study controlled nuclear fusion technology......"

"Fifty years, it will not be possible!"

When the news spread abroad, it also caused a large number of media reports, almost all of which were not optimistic, "This kind of large-scale engineering project, even if it is formally established for research, there is a high probability that it will die halfway, and no matter how much manpower and material resources are invested, it is meaningless." ”

"Modern research on nuclear fusion is simply impractical."

"Even Ameriken and Europe, which have more advanced technology, will not be able to start nuclear fusion research for the time being......

"It's probably just a slogan, and it's impossible to really invest in research."

“……”

The international media not only made judgments, but also conducted a series of analyses, and the comparison was made with the large-scale example collider project.

For many years, the Large Particle Collider project has been being demonstrated in China.

The purpose of this project is to replace the aging positron collider, so that the country has the top collider to conduct research in related fields.

The Large Particle Collider project, with equipment, technology, and theory, is certainly no problem in manufacturing, and the only thing that needs to be demonstrated is whether it is worth investing.

Even such a project has not been officially launched until now.

Controlled nuclear fusion is a century-old project and is considered the main energy technology of the future, but the threshold for research is too high.

Germany, for example, has demonstrated that the tokamak is a well-built device, with a budget of more than $100 billion alone.

After spending hundreds of billions of dollars, it is not that the research can be completed, but the nuclear fusion reaction can be carried out inside the device, and the results are still limited to the laboratory, not the application field.

Naturally, such a project could not be passed.

The reason why the research of controlled nuclear fusion is not optimistic is that there are too many technical difficulties to be solved.

In response to the hot spots of public opinion, the "Times" of the Eagle Country summed up several technical problems that are difficult to break through, the first of which is the difficulty of ignition.

Every ignition of nuclear fusion requires the creation of a high-temperature and high-pressure environment.

It is too difficult to manufacture a high-pressure environment, and it is generally replaced by a high-temperature environment, which requires an environment of at least 100 million degrees Celsius.

The second point is that the computer simulations are not accurate.

It's a math problem.

All studies of controlled nuclear fusion cannot avoid plasma, and the problems surrounding plasma, including instability, turbulence, and the underlying equations that govern the elusive behavior of plasma, can only be approximated.

In fact, it is like Newton's law that restricts the motion of the three-body body, the NS equation that restricts the motion of fluids, and the Boltzmann equation that restricts the motion of a large number of molecules.

These partial differential equations are very difficult to solve, and most of them can only find approximate solutions.

There is also the question of materials.

The reason why nuclear fusion can be called infinite energy is because the deuterium in seawater is almost "unlimited" to humans.

But the problem is that it's too difficult to use only 'deuterium'.

At a temperature of 100 million degrees, the reaction cross-section of deuterium-deuterium is nearly two orders of magnitude lower than that of deuterium-tritium, and when the temperature rises to the order of one billion, the toughness radiation will be greatly enhanced, and it will become extremely difficult to achieve an output greater than the input.

If 'tritium' is used, the problem is also obvious.

Tritium is radioactive, almost naturally absent in nature, human production capacity is extremely limited, and the lithium used in tritium propagation is also limited.

Of course, the biggest difficulty is also indispensable, "How to achieve output greater than input?" ”

From the input point of view, the power of the radio frequency waves, neutral beams, and lasers used to heat the plasma is less than or even much less than the electrical power consumed to produce them.

From an output point of view, the efficiency of the energy of neutrons in converting into usable heat is limited, and the efficiency of thermal power generation itself is not high.

Wait a minute.

There are many difficulties to overcome in the study of nuclear fusion.

When the news came out, both at home and abroad, there was almost no optimism that the nuclear fusion project could really be launched.

Such a study would not even be able to pass the argument.

But in fact, there is still a foundation for nuclear fusion research in China, and many scholars support the project demonstration.

Tang Jianjun researched and manufactured the tokamak device to perfect the problem of annular magnetic confinement.

In addition, the Circulator M device manufactured by the Southwest Research Institute of Nuclear Industry, which is called an artificial sun, has also been successfully discharged.

Although all the problems of nuclear fusion technology have not been solved, China has mastered the design, construction and operation of large-scale tokamak devices.

These are the foundations.

……

Public opinion at home and abroad is not optimistic about the research of nuclear fusion.

Most people think that 'the rumor is just the rumor', just the news that catches the wind, and even if you have the intention to do research, it is not easy to pass the argument.

This kind of super-large research project is not a one-person decision-making, it needs the support of many institutions and scholars to carry out, and the first step is to conduct technical demonstration, the purpose is to discuss the problems that may be encountered in the research, whether there are solutions, and the division of labor in follow-up research.

If there is no technical demonstration, that is, there is no reliable solution to some problems, the project will not be able to start at all.

Some people don't see it that way.

For example, the professors at Xihai University who are familiar with Wang Hao.

They also know that there are many problems in fusion research, some of which are technically impossible to think of at the moment.

However, in comparison, they prefer to believe in Wang Hao.

There is no doubt that the nuclear fusion research project is related to Wang Hao, and since it is a project that Wang Hao participated in and led, it seems that any technical difficulties are not a problem.

Some people react very quickly.

For example, Zhang Zhiqiang.

After Wang Hao returned to Xihai City from the capital, he was not in a hurry to work, but accompanied Su Yingxue to rest at home for a few days.

After that, he returned to Seohai University.

When he entered the office of the Mason Number Lab, he had just sat down to look at the materials when he saw Zhang Zhiqiang walking in with a large box.

Wang Hao stood up and glanced at it, and said with a puzzled face, "Lego? ”

"yes."

Zhang Zhiqiang put the Lego toy aside and said with a smile, "Isn't this my brother and sister about to give birth?" I'll give you a gift in advance, congratulations! ”

“……”

Wang Hao looked at Zhang Zhiqiang with a strange expression, it's nothing to give a small gift to the child, but the problem is ...... The baby hasn't been born yet!

Lego?

This kind of toy is not something that newborn babies can play with.

In addition, Zhang Zhiqiang will take the initiative to give gifts?

Zhang Zhiqiang immediately said his true purpose, he smiled and said, "Wang Hao, we are best friends, right?" For a project as big as nuclear fusion, you have to think about me......"

"Not to mention other high-end technologies, you can also participate in a project to build a simulation system."

Wang Hao shook his head helplessly, "This project is not necessarily. Moreover, you go through the back door......" Before he finished speaking, Zhu Ping and Luo Dayong pushed the door in.

Zhu Ping's face was full of enthusiasm.

She leaned over to Wang Hao's side and hugged his arm back and forth, "Wang Hao, the nuclear fusion project can really be launched, you have to think about our ......"

"I'll forget it."

"Dayong also has the heart to join the project, and it is okay to enter the math group and the calculation group."

Wang Hao turned his head to look at Luo Dayong, and almost wrote the words "you don't care" on his face, but Luo Dayong turned a blind eye and gave a look of 'who takes advantage is not necessarily'.

Now it's very helpless.

Wang Hao felt that he was being taken advantage of, so he quickly pulled out his arm, coughed lightly, and said, "You" You don't have to be like this. ”

"I'll tell you directly."

"First of all, this project may not necessarily pass. If the project is approved, an experimental base will be built in Xihai and its surroundings, and our laboratory will also be one of the participants. ”

"Although it may be an unimportant participant, we can definitely get a part of the work for projects such as computer simulation systems and automatic control systems."

"It's a huge project, so you don't have to worry about not being able to get involved."

"Of course."

"If you want to lead a team to take on a project, you still have to build a team and apply by yourself, and it depends on your ability."

After Wang Hao finished speaking, several people took a long breath, they really wanted to participate in such a major project, but it was also an honor to participate in it.

The atmosphere in the office suddenly came alive.

Zhang Zhiqiang patted his chest and said, "Da Luo, let me tell you, in this way, you and I, plus Teacher Qi Xiao and others, when the time comes, let's apply for an independent project together." ”

"With my level and qualifications, there must be no problem in preparing."

Wang Hao said, "I want to remind you, Brother Zhang. If you want to apply independently, your competitors include top mathematical computer institutions and teams such as the Institute of Information of the Academy of Sciences and the Computer Center of Mizuki University. ”

"Compared to these top teams, you have to think about your strengths in advance and be well prepared......"

Luo Dayong nodded approvingly, "Yes, where are your advantages?" ”

"Advantages, Advantages......"

Zhang Zhiqiang opened his mouth forcefully and didn't speak for a long time.

If compared with ordinary mathematical computer scholars, his qualifications and technical level are quite good, but compared with the top scholars in China, the level of qualifications has no advantage.

So where are the advantages?

Luo Dayong said, "Lao Zhang, you don't have to think about it, I've already helped you think of it." ”

"What advantages?"

Zhang Zhiqiang looked over with a puzzled face.

Luo Dayong stretched out his finger and pointed to the top of his head, nodded seriously, and said, "Baldness, is your advantage, the roller skating rink in the middle, the barbed wire on both sides, the top scholar of the standard." ”

"Your image, when you stand in front of the expert review, you will first add ten points to the image."

“……”

Zhang Zhiqiang touched the top of his smooth head, and shouted with a dark face, "Damn, it's decided, I'll go for a hair transplant tomorrow!" ”

……

The tech sector moves fast.

While the discussion was still going on in the media, the science and technology department had already organized the first technical demonstration meeting.

Many scholars who received the news were surprised.

Generally, large-scale engineering research projects need to be repeatedly discussed internally, and some top scholars should be convened in the process to see what their opinions are, and only after there is enough support from scholars and institutions will a large-scale technical demonstration meeting be organized.

This technical demonstration meeting can also be classified as an internal discussion, and it is still confidential to the outside world, but there are several institutions that have received the news, and the number of scholars participating has exceeded 100, which has long been out of the scale of small discussions.

Institute of Physics, Institute of High Energy Physics, Southwest Research Institute of Nuclear Industry, Institute of Nuclear Physics, and Research Center for Superconducting Materials, Academy of Sciences......

Wait a minute.

A lot of big organizations have been heard.

They sent a team of heavyweight experts to the main hall of the conference center where the demonstration meeting was held.

After entering the conference center, the scholars were still incredulous, "I didn't expect to have a debate meeting so soon." ”

"It seems like I only saw the news a few days ago......"

"This project is related to Academician Wang Hao, right? There should be a direct link. ”

Everyone else nodded in approval.

Now it is no secret that the main core technology to control nuclear fusion is not a secret, and many people know that the strong annihilation force field generator is suitable as a 'container' for nuclear fusion reactions.

In this regard, there are many reports abroad.

For example, the International Organization for Annihilation Theory has proposed that nuclear reaction research can be carried out in the strong annihilation force field device, one is that the anti-gravity field can reduce the activity of particles, that is, control the reaction speed, and the other is that the outer strong annihilation force field can absorb energy, so that the reaction vessel can withstand higher temperatures and energy.

While the scholars were discussing, Wang Hao, Tang Jianjun and others entered the venue together.

Wang Hao did not come alone, he temporarily formed a small team, including Tang Jianjun of the Institute of Nuclear Physics, Fang Yongsheng of the Institute of High Energy, Li Chun of the Institute of Nuclear Energy, Zhao Jiarong of the Center for Superconducting Materials, Ding Zongquan of the Wuhan Iron and Steel Research Institute, and others.

Their respective research can be used as a technology accumulation for controlled nuclear fusion.

For example, Ding Zongquan's team used first-order iron to create a steel with a very high melting point and toughness, and also has certain magnetic properties, which can be used as a material to make the spiral magnetic field on the outer layer of the container.

The leading party of the debate is the science and technology department.

Mr. Xu came to the scene to set the tone for the demonstration meeting, and he was the first to speak, saying, "The content we discussed at this meeting is the technical problems of controlled nuclear fusion engineering. ”

"It's an early discussion meeting, so don't be stressed."

"If you have any questions or want to know, you can ask and say, and we need to discuss and study together to know what problems will be encountered in the research and how to solve them......

After Mr. Xu set the tone of the meeting, it was Wang Hao's turn to play, and Tang Jianjun spoke as a representative.

His job is to elaborate on the existing technical base.

Tang Jianjun is very enthusiastic about the research of nuclear fusion, he very much hopes that the demonstration meeting can be passed, and he also made a fine PPT to list the main problems.

The first challenge is ignition technology.

The ignition of nuclear fusion reactions requires very high-end technology, and there is a saying in public opinion that "hydrogen bombs need atomic bombs to detonate".

This statement is not an exaggeration.

The central temperature of the atomic bomb can reach 100 million degrees Celsius instantly, which is just the temperature condition for detonating the hydrogen bomb.

However, on the PPT made by Tang Jianjun, there is only one title for the ignition of nuclear fusion.

When he made an introduction, he also skipped to the next question, "Let's look at the second question, the high magnetic field environment manufacturing and reaction control ......"

An old academician reminded below, "Academician Tang, you haven't said the first question yet. ”

"Although we already have ignition technology, the new reaction vessel is a strong annihilation force field device, and the inside is an anti-gravity field, how to achieve nuclear fusion ignition in the anti-gravity field?"

Everyone looked at Tang Jianjun on the stage.

Tang Jianjun smiled confidently and said, "Academician Zhou, this question can be skipped, because we already have a perfect nuclear fusion ignition technology. ”

"Perfect fusion ignition technology?"

"Yes."

Tang Jianjun nodded seriously, "This ignition technology does not need to restart the equipment, nor does it need to interfere internally, and it can be ignited externally at any time." ”

After speaking, he looked at Teacher Xu.

Teacher Xu nodded in agreement, "That's right, we already have a perfect ignition technology, so there is no need to discuss this issue." ”

"Hula......"

The venue was in an uproar.

All the scholars attending the meeting did not expect that Tang Jianjun had just come to power and broke the big news that they actually had a brand-new, so-called 'perfect' ignition technology.

This technology doesn't even need to be discussed?

Teacher Xu nodded in approval?

What does it mean?

This shows that the technology has been perfected to solve any problem encountered during the ignition process!

"When did we have such high-end technology?" Many scholars couldn't help but discuss it, and they were so surprised.
