Facing Fang Xu's skepticism, Lu Yongchang could only gently skim his mouth.
This is what he said to himself!
If Fang Xu knew that this drawing was something he had spent a night jerking out, he would probably be on the autopsy table by now, right?
"It's just a drawing of a reactor, it's still far from the entire controlled fusion reactor!"
Hearing Lv Yongchang's Versailles-filled words, Fang Xu's mouth twitched violently twice.
In his own 45-year-long life experience, Lv Yongchang should be the most capable of pretending he had ever seen, right?
But soon, he sensed something a little different.
"Wait!"
"This reactor ..."
Fang Xu's voice made everyone's hearts clench.
Hong Qiming also couldn't help but look towards him.
Could ... the drawings of this reactor be wrong?
"This is not a Tokomak device!"
Fang Xu shouted with some surprise!
A few smiles flowed out of the corners of Lv Yongchang's eyes.
Worthy of being Academician Fang, he really couldn't hide it from him!
"Of course this is not a Tokomak device!"
"This is a star imitation device."
Lv Yongchang said with a light laugh, "If my calculations are not wrong, the controlled fusion duration of ITER should be within 30 minutes, right?"
Fang Xu's eyes twitched slightly as he nodded lightly, "That's right, the results of the latest experiment, the fusion reaction sustained for about 26 minutes."
"Could it be that ..."
"Hehe ..." Lv Yongchang smiled slyly, "Unsurprisingly, soon, ITER will touch the ceiling of the Tokomak device!"
Fang Xu's pupils snapped, "Are you saying ... that the tokomak device is not the optimal solution for realizing controlled nuclear fusion?!"
Lv Yongchang nodded his head to affirm Fang Xu's statement.
"How is it possible ... If that's true, then wouldn't mankind be advancing on the wrong path for decades?!"
Fang Xu froze in place and muttered.
He was somewhat unable to accept Lv Yongchang's statement!
Lv Yongchang was naturally aware of Fang Xu's complicated feelings at this time.
In his previous life, in order to break the monopoly, all of Xia's scientific research power had been invested in the research and development of the Tokomak device!
However, no matter how hard they tried, the sustaining time of controlled nuclear fusion could not exceed thirty minutes!
At that time, this was a fatal blow to the confidence of all researchers!
If not for Fang Xu learning about the defects of the tokomak device by chance, it was estimated that Xia was going to make a mistake on the road to realizing controlled nuclear fusion to the end!
"How do I ... I verify your claim?!"
Fang Xu was worthy of being the current top scientist of Xia, after a brief moment of disorientation, he reacted at the first opportunity and asked Lv Yongchang in a deep voice.
Lv Yongchang shrugged his shoulders and said with a glib face, "It's very simple, all we need to do is to find the most basic star imitation machine, build a reactor with that material I deduced, and then ignite the nuclear fusion, and then naturally, we can get the verification."
Fang Xu's eyes twitched slightly.
He remembered that in the laboratory, there was indeed an "outdated" star imitation device that he had bought at a large price in the past.
"Wait!"
Hong Qiming's loud voice suddenly sounded from the side.
"Which one of you ... explains to me, Star Imitation Device and Tokomak Device, what do they mean?"
While speaking, Hong Qiming cast his gaze towards Lu Yongchang.
Guan Hua Liang and Fang Xu, who saw this scene scene, took a step back and handed the stage over to Lv Yongchang.
Lv Yongchang pondered for a moment and spoke, "Ministry Hong, you should be clear that controlled nuclear fusion requires a powerful magnetic field to restrain the fusion material, right?"
Seeing Hong Qiming nodding, Lv Yongchang was slightly relieved.
This was a good explanation!
Otherwise ... he would have needed to go over the principles of controlled nuclear fusion from the beginning!
It was also something that could be solved in a few words, but, after all, it was a bit more troublesome!
"Simply put, the toroidal spiral cage generation of a tokomak device requires a plasma current, the star imitator does not, it can generate a twisted toroidal cage directly from an external coil."
"So ... what's the difference between the two? Aren't they both generating magnetic fields?"
A hint of confusion appeared in Hong Qiming's eyes.
"Pah!"
Lu Yongchang lightly snapped his fingers.
"That's the point of what I'm going to say!"
"In the Tokomak device, the plasma current is as high as tens of millions of amperes, and such a huge current is bound to bring about countless problems."
"For example, distortion modes, magnetic surface tearing, magnetic island generation, and so on!"
"All of this reduces one's ability to constrain the plasma."
"Resulting in consequences as light as flame out, or as heavy as explosion!"
While saying this, Lu Yongchang made an explosive gesture.
Hong Qiming nodded his head as if he understood.
Although he didn't understand the various specialized terms that Lv Yongchang said in his mouth, he understood the last sentence.
What about the tokomak device that will explode when it is set aside?
Hong Qiming looked at Academician Fang Xu, who was standing next to him, with a complicated face.
Facing Hong Qiming's gaze, Fang Xu could only nod helplessly and said, "It's a possibility that exists, but ... as of now, the tokomak device hasn't had such a serious failure!"
"Not now, what about later?" Lv Yongchang said in a light tone, "By the time the fusion sustaining time is raised to 30 minutes, perhaps, serious consequences will appear!"
Fang Xu's body stiffened violently, and he exclaimed out of breath, "Are you saying that the Tokomak device after thirty minutes of fusion will explode?!"
Lv Yongchang nodded with a complex expression, "That's right, this is the biggest trap of the tokomak device."
"Although the poleward magnetic field formed by the plasma current makes the composition of the magnetic cage very simple, the high temperature and the super high current will eventually lead to some accidents."
Fang Xu came to a realization, "So it is! So that's how it is!!!"
"What about the Star Imitation Device?" Hong Qiming gulped slightly and asked in a low voice.
He suddenly had a feeling that the young-faced sophomore in front of him was simply like an old professor who had been immersed in it for decades in this regard!
Even Fang Xu, in front of him, was a student-like existence!
Hearing Hong Qiming's question, Lv Yongchang said lightly, "A star imitation device would be simple, just need to get a closed, twisted ring-like magnetic cage inside through the external coil!"
Hong Qiming: "???"
"So simple? Then why didn't you use a star imitation device before?!"
Fang Xu slanted a glance at Lv Yongchang without any good humor and spoke again to explain, "The difficulty of the Star Imitation Device is the manufacturing of the external coils."
"First of all, the shape of the external coil is irregular, which is a major difficulty in manufacturing."
"On the other hand, to form a strong enough magnetic field, the material of the coil, preferably using a superconducting coil, increases the difficulty even more."
"After all, there is no breakthrough in room temperature superconducting technology yet."
Lu Yongchang's ghostly voice came from the side, "What if, I am able to solve the room temperature superconducting material?"
