A physical examination made Xu Chuan a little confused to find that two people around him were suddenly forcibly stuffed.

A life assistant who looks about the same age as him, and a housekeeping aunt.

According to the meaning of the old man and the academician Qiu Kaiji who gave him a physical examination, his body is 'urgent' to recuperate, and he can't eat those junk food or anything anymore.

So I stuffed a life assistant and a housekeeping aunt over.

Xu Chuan looked confused, staring at the lady standing in front of him with a straight posture and a heroic military atmosphere.

This is the life assistant he was looking for?

Isn't it a little too young?

Although he is not yet twenty-five years old on the surface, his actual age is not too young. This serves as his life assistant, who will take care of whom in the future?

However, the lady on the other side didn't think about it so much, she looked at Xu Chuan and showed a standard smile.

"Hello Academician Xu, my name is Tang Sijia. I will be responsible for your next physical health and physical recuperation. I hope that the future work will be smooth and enjoyable. ”

"Ahem, hello." Xu Chuan coughed lightly, and said hello a little uncomfortably, and was arranged to be a life assistant to take care of his life, which was the first time he had experienced it.

After all, if you were born in a rural area, even if you are now at the top of the scientific world, it is difficult to change the idea that you have always had.

But this matter has already been decided, and he is embarrassed to return people again.

After a brief understanding of each other, Xu Chuan also returned to the Beihai Hotel, ready to pack his luggage and go back to Jinling.

After the ignition of the dawn demonstration pile is successful, the follow-up is to repeat the ignition test, and then carry out the work related to grid connection.

After the 2021 year of the Gregorian calendar, he will probably be able to step down from the position of the chief person in charge of Qixia's controllable nuclear fusion project.

At that time, it will be time for him to return to NTU for a few classes.

Speaking of this, Xu Chuan is still quite guilty, after all, he has a full professor position at NTU, but he has not taken classes in the past two years, nor has he taken students. It's kind of a prostitute of NTU's salary and benefits for nothing.

Although NTU probably won't care about this kind of white prostitution, and even maybe I hope there will be more of this kind of white prostitution.

But for him, it's still quite unbearable.

Smoothly returned to the Beihai Hotel from the sanatorium, unexpectedly, Xu Chuan met an acquaintance here.

"Hello, Academician Xu."

In the lobby on the first floor of the hotel, a middle-aged and elderly man stretched out his right hand with a smile on his face, and said in a familiar greeting: "Please allow me to introduce myself, Academician Xu, I am the director of CCTV, Xiong Weizhao." ”

Looking at the smiling CTV director in front of him, Xu Chuan skillfully stretched out his right hand and shook his hand: "Hello, Director Xiong." ”

Although it was a little unexpected that the director of CTV would come over to interview him or something, he was no stranger to this kind of thing.

Since he led the Qixia controllable nuclear fusion project to successfully complete the ignition, there have been many people who have visited him recently.

To put it mildly, the director of CTV, among these people, the position level may still be relatively low.

Xiong Weizhao clenched his hands tightly and shook his hands enthusiastically, and said with a smile: "Hello Academician Xu, let me introduce to you, this is Sun Yutong, our excellent media reporter and host of CTV." ”

Behind him, Sun Yutong, a beautiful reporter with a delicate face, stood up with a smile and greeted Xu Chuan: "Academician Xu, hello." ”

Xu Chuan nodded with a smile and said hello: "Long time no see, Reporter Sun." ”

Hearing that he still remembered himself, Sun Yutong was slightly stunned for a moment, and then a bright smile appeared on his face: "I didn't expect you to remember me." ”

Xu Chuan smiled and said, "For beautiful things, people will always be impressed. ”

On the side, Xiong Weizhao looked at the friendly exchange between Xu Chuan and Sun Yutong, and a mysterious smile also appeared on his face.

In fact, Sun Yutong is not strictly speaking a core media reporter for CTV One, and today's interview should not have been hers. However, after learning that she had interviewed this Academician Xu several times before, and had a good relationship with Academician Xu, he took the initiative to bring Sun Yutong over today.

After all, with the current level of Academician Xu, even if he wants to meet, it is not so easy.

If you want to do an interview with this person, it depends on whether he is in the mood or not.

At least bringing Sun Yutong over today is the right choice. The relationship between the two seems to be much better than he expected, and the interview should be stable.

After the two talked about the old days, Xiong Weizhao said: "I don't know if Academician Xu is convenient, we want to do an interview with you about the field of controlled nuclear fusion." After all, we are the first country to realize this great technology, and it is still necessary to publicize it to the outside world and boost national self-confidence. ”

After a slight pause, he continued: "Of course, regarding this interview, we applied to the above, and the above also agreed. Including the interview questions, we have carefully selected them and will not touch on some technical aspects of controlled nuclear fusion. ”

"In addition, after the interview, we will also focus on reviewing the relevant content and confirm that there are no problems before publishing it."

"The main thing is to make a proper science popularization for controlled nuclear fusion to the general public, after all, you are the father of controlled nuclear fusion, and your voice in this field is more convincing than others."

Hearing what he said, Xu Chuan didn't refuse, nodded, and said, "Yes, but the high-speed rail on my side is more than two o'clock in the afternoon, I'm afraid there is not a lot of time left for you." ”

"If the interview is long, you can also take the time to go to Jinling."

Xiong Weizhao glanced at his watch and hurriedly said, "Enough is enough, I have already asked the hotel manager to prepare the conference room, so it will delay Academician Xu for some time." ”

As he spoke, he glanced at Sun Yutong.

Sun Yutong quickly stepped forward and said with a smile: "Trouble Academician Xu." ”

"You're welcome, it's just a trifle."

The group came to a conference room in the Beihai Hotel, and after a brief chat, Sun Yutong asked with a smile: "Academician Xu, how about we officially start the interview?" ”

Xu Chuan nodded and said, "Yes." ”

"The first question is about the future. After the realization of controlled nuclear fusion technology, we all want to ask, what changes can it bring to our lives, the earth's environment and other aspects? ”

Hearing this conventional question, Xu Chuan smiled and said, "If you want to say that after the realization of controlled nuclear fusion technology, it will bring too many changes." ”

"I'm afraid that I may not be able to finish it for three days and three nights."

After a slight pause, he thought for a moment, and then said, "If you want to say that the biggest and most obvious change is related to electricity. ”

"If you are friends who live in Jinling, even if it hasn't started yet, they should be able to appreciate the change in electricity prices. In the past, the price of electricity for civil life in Jinling was about six cents per hour, but after the dawn demonstration reactor is completed and connected to the grid, the electricity bill will become two cents per hour, a drop of three times. ”

"For friends who live in the hot summer and have air conditioning, the burden of electricity bills will be drastically reduced. Just like some friends on the Internet said, you can go out with an air conditioner 24 hours a day in the future. ”

Smiling, Xu Chuan continued: "Of course, I personally don't recommend this. After all, it's too tiring to go out with an air conditioner on your back. ”

Hearing this, Sun Yutong couldn't help but smile, she didn't expect that this Professor Xu would have such a humorous side.

Xu Chuan didn't pay much attention to this aspect, and continued: "For society, the reduction of electricity bills will mean the rapid development of all walks of life, and these are predictable problems. ”

"As for the impact on the earth's ecological environment and environment"

After thinking about it for a while, he described it in the simplest way: "After the realization of controlled nuclear fusion technology, problems such as the greenhouse effect and excessive carbon dioxide emissions will be greatly improved." ”

"It depends on the kind of energy used, which will shift from traditional fossil energy to electricity with controlled nuclear fusion."

"It is well known that the use of fossil fuels, whether coal, gasoline, natural gas or others, releases a lot of total heat and greenhouse gases when they are burned to do work. These are one of the main reasons for the rapid changes in the earth's ecological environment. ”

Sun Yutong nodded and asked curiously: "Can it be understood that the global ecological environment, carbon neutrality and other issues will be alleviated or even solved in the future?" ”

Xu Chuan nodded and said, "You can say that." With the implementation of controlled nuclear fusion technology, these problems can be greatly alleviated. Even in the relatively long run, they can be completely solved. ”

"After all, the deuterium-tritium burned by controlled nuclear fusion technology releases neutrons and helium-3. In the process of generating electricity, neither carbon dioxide nor other greenhouse gases are present. ”

"And for the use of fusion thermal energy, nuclear fusion devices are also far more powerful than ordinary power generation equipment."

Sun Yutong nodded and continued: "The second question was picked out from the Internet, before asking this question, I would like to ask Academician Xu whether you have seen or understood the "Wandering Earth" or the movie? If not, we'll skip this question. ”

"Of course, this paragraph will also be cut out in the follow-up report."

Xu Chuan glanced at her with some curiosity, nodded inexplicably, and said, "I have some understanding." ”

Sun Yutong: "That's the case, some netizens want to ask you, in the movie "The Wandering Earth" released last year, the principle of the planetary engine mentioned in the movie is nuclear fusion, what do you think of this sci-fi direction? In your opinion, will the use cases of nuclear fusion such as planetary engines shown in the movie become a reality in the future? ”

Hearing this question, Xu Chuan raised his eyebrows with some interest.

I have to say that this question is still a little more than the previous question.

After thinking for a while, he organized his language and said: "First of all, it is certain that the use of nuclear fusion as an energy source to drive a huge planetary engine is the imagination of the science fiction author, and it is also the author's expectation for future science and technology, especially for the way to solve the human energy problem - controllable nuclear fusion energy." ”

"For controlled nuclear fusion technology, once it is applied, projects such as desalination and interstellar travel, which are discouraged by huge energy consumption, are expected to develop rapidly with the support of nuclear fusion."

"As for the hard-core technologies such as planetary engines in the movie, it is indeed a bit out of reach with the current cognition. But with the major discoveries and breakthroughs in science and technology in the future, it may become a reality in the future. ”

"Of course, if such a huge planetary engine is to be built, both for structural materials and for controlled nuclear fusion itself, it is a great luxury, and it will take at least a few more rounds of breakthroughs before there may be hope."

"If I'm not mistaken, in planetary engines, the fusion feedstock used is the common stone. The principle is "heavy element fusion". ”

"The fusion of heavy elements is a more advanced form of nuclear fusion reaction, which generally only occurs inside massive stars, and it is impossible for heavy element nuclear fusion to occur inside stars as massive as the sun, and only stars more than eight times more massive than the sun can achieve iron fusion."

"The controlled fusion technology we are currently using is deuterium tritium, an isotope of hydrogen. It only needs about 15 million degrees Celsius to reach fusion conditions. But the fusion of helium, which is one level higher, would require nearly 200 million degrees Celsius. ”

"But if you want to make conventional stones, the main components of which are generally silicon dioxide, carbon carbonate, calcium hydroxide and other substances produce nuclear fusion phenomena, the temperature required needs to be at least two billion degrees Celsius."

"Although, in theory, it can be done."

"But this technology, for the current level of human technology, this is an unimaginable nuclear fusion technology. While it is possible in theory, it is too difficult to implement in reality. ”

"Even I can't give a predictable time to achieve it."
