Now that we have a certain direction, the next thing will be much easier to handle.
Although Zhang An questioned Xu Zhou's suggestion that mankind as a whole had taken decades of detours in terms of controllable nuclear fusion, he was still very interested in Xu Zhou's ideas.
Xu Zhou was right in saying that practice is the only criterion for testing truth. He also wanted to witness whether Xu Zhou, who had always been invincible, could solve the problem of controllable nuclear fusion this time.
At this time, Lao Zhou suddenly said something weakly.
"By the way, I still don't know the difference between a tokmak and a stellarator..."
Although Zhou Guofu was called to help, he actually had little contact with controllable nuclear fusion. He was focusing on subjects with different directions, so he naturally knew very little about it.
Although everyone has heard of controllable nuclear fusion, he has even heard of Tokomak, stellarator and the like.
But he still didn't know the specific difference between these things.
At this time, Zhang An was a little speechless. After talking for a long time, you still don't know the difference!
Xu Zhou was also a little bit dumbfounded.
"Mr. Zhou should know that controllable nuclear fusion produces reactions through extremely high temperatures, and ultimately requires a magnetic field to restrain materials and particles, right?"
Zhou Guofu nodded immediately, of course he knew this.
When Xu Zhou saw him nodding, he continued confidently:
"Then let's switch to a simple concept, which means that whether it is a tokmak or a stellarator, it needs to generate a magnetic field."
"To generate such a magnetic field cage in a tokmak device requires a plasma current, which is not required if a stellarator is used. This is the biggest difference between the two."
After listening to this, Zhou Guofu pondered a few words carefully, and finally looked at Xu Zhou and said:
"So the problem is these plasma currents?"
"That's right."
Xu Zhou snapped his fingers, looked at him and continued:
"The Tokmak device requires tens of millions of amperes of plasma current. Such high currents will cause many unpredictable problems during the intervention of the experimental device."
"For example, the formed magnetic field is torn apart by the current, or an unstable structure appears in the magnetically confined fusion plasma, which increases the plasma energy loss, decreases the reaction amplification factor, and reduces the reaction efficiency."
"And the consequences of these, can you imagine?"
"Will it explode?"
Zhou Guofu swallowed his saliva and asked again, but saw Xu Zhou's expression suddenly relaxed.
"That's not the case. The conditions for nuclear fusion are extremely harsh. As long as any abnormality occurs, the reaction will stop directly."
Zhou Guofu breathed a sigh of relief, but he also reacted immediately.
The reason why nuclear fusion is said to be safe enough is actually here. If it goes out of control, the reaction will be terminated directly.
If such an accident occurs in nuclear fission, the loss of control will basically have to wait for the fission reaction to end, and the final product will be a variety of extremely dangerous radioactive materials.
"but……"
At this time Xu Zhou continued to laugh and said:
"Although it will not explode, the out-of-control plasma has all deviated from the predetermined orbit. Losing their restraints, they may directly penetrate the reactor. It is not impossible to slap you in the face..."
When Zhou Guofu heard this, his whole body tensed up.
I almost blurted out the words in my heart.
The ions heated to hundreds of millions of temperatures were thrown in the face... The others will probably be gone by then, right?
"I see."
Zhou Guofu touched his chin and finally came to a conclusion.
"Anyway, the Tokmak device is unreliable. There is a danger of throwing high-temperature ions in my face at any time, right?"
"Is the imitation star ring okay?"
At this time Zhang An also followed:
"Yes, doesn't the stellarator have the same problem? How to generate magnetic field binding?"
Compared to Zhou Guofu, who only knew a little about Tokmok, Zhang An had a deep understanding of Tokmok.
When Xu Zhou mentioned these disadvantages, he immediately thought of the problem.
But at this time Xu Zhou shook his head as a matter of course.
"The stellarator is much simpler. It does not require high plasma current intervention. It only needs to reinforce a coil on the periphery to independently generate a magnetic field."
As he spoke, Xu Zhou gestured with his hands.
"It's like putting an outer enclosure on the stellarator, creating a magnetic cage to cover it!"
"And this is the difference between the two reactors!"
Although Zhou Guofu still had a vague understanding of it after hearing this, it did not affect his preference for star-like devices.
But at this time Liu Zhongmin interrupted with some embarrassment:
"Ahem, Xiao Xu."
"It's not that we have to argue against you, it's just that I thought of a new problem after listening to your plan..."
Zhou Guofu and Zhang An looked at Liu Zhongmin at the same time.
Liu Zhongmin has remained silent from the beginning until now, which proves that he agrees with Xu Zhou's theories.
But now he must have discovered some problem, so he suddenly spoke.
And Liu Zhongmin was indeed the same. He looked at Gu Fan and asked seriously:
"As you just said, Xiao Xu, the Tokmak device may indeed have such a problem, and the stellarator can indeed solve the problem of the magnetic field cage as you said."
"But let's not forget the most important point, which is also the most difficult point."
"The reinforcement of an independent coil that you are talking about to generate a magnetic field...is this the biggest difficulty that is currently difficult to achieve, right?"
Liu Zhongmin saw Zhou Guofu looking at him with a confused expression, and complained speechlessly:
"You don't really think that just a random coil will be enough, do you?"
These words made Zhou Guofu blush.
Damn it, three people who know how to bully me and a cross-field person...
"The biggest difficulty of the stellarator is the production of the coil. The first is the irregular shape, which makes it difficult to form a production standard."
"Of course, if this is the only problem, it can be solved with some time. The most important thing is the material of the coil. In order to form a strong enough magnetic cage, there is no other choice of material. It must be a superconducting coil!"
At this time, Zhang An instantly understood what Liu Zhongmin meant, and then said:
"Yes, there is currently no breakthrough in room temperature superconducting technology in the world!"
Speaking of this, Zhou Guofu also said that he knew about room-temperature superconductor technology. Some time ago, before the zombie virus appeared in Bangzi Country, he boasted that his country had conquered this technology.
It was very popular at the time, and countless countries and media reported it.
You must know that if there is a breakthrough in room temperature superconducting technology, it will be of great help to research in many fields around the world!
But unfortunately, this technology was soon revealed to be an own incident.
It is not a so-called room-temperature superconductor at all. The many restrictions make it completely useless in many projects.
And the propaganda cannot be copied. This news immediately made many countries laugh out loud.
But now the problem of room temperature superconductivity has not been solved, which is also the main reason hindering the development of stellarators!
"Ahem...if you say..."
"I mean, if I can solve the problem of room-temperature superconductors...then will the stellarator be able to achieve the results I mentioned?"
silence……
At this moment, you could probably hear a pin drop in the office. All three people's necks were stiff, as if they were rotating shafts that had not been oiled for a long time, and they turned jerkily to look at Xu Zhou.
Liu Zhongmin opened his mouth and swallowed again.
Finally he said in a difficult tone:
"Xiao Xu... I'm getting older and my ears are no longer working... You mean you can create room-temperature superconductivity?"
At this time, Lao Zhou also followed behind and said with a smile:
"Although I don't understand controllable nuclear fusion, I still understand superconductivity... Superconductivity at normal temperature and pressure is no joke!"
Zhang An also pushed up the glasses on the bridge of his nose, his expression numb, and his eyes lacked some light.
"I can create room-temperature superconductivity... It feels like I have lived on a dog for more than thirty years!"
Little did he know that this sentence directly offended the two elderly people on the side.
I saw both of them glaring at Zhang An.
You, an academician who is less than 40 years old, has survived a dog. How can it be that these two old guys who are almost 60 years old have not even survived a dog?
Damn it, who is there between Yin and Yang?
Zhang An immediately laughed a few times when he realized this.
At this time, Xu Zhou stood up and smiled at several people:
"Give me a few days and I'll give it a try. The three of you will continue to help me complete the preparations. I need the stellar simulator and new molecular materials from the Dragon Academy's warehouse."
"When I get the results here, we can start the formal conquering phase of controllable nuclear fusion!"
