Faced with Fang Xu's doubts, Lu Yongchang could only curl his lips gently.

I'm just talking too much about this!

If Fang Xu knew that he had spent all night to get the drawings, he would probably be on the dissection table now?

"It's just a drawing of a reactor, and it's still far from the entire controllable nuclear fusion reactor!"

Hearing Lu Yongchang's words full of Versailles, Fang Xu's mouth twitched twice.

In his 45-year life experience, Lu Yongchang should be the one he has ever seen, right?

But soon, he noticed something strange.

"etc!"

"This reactor..."

Fang Xu's voice made everyone's heart tugged.

Hong Qiming couldn't help looking at him.

Could it be... the drawings of this reactor are wrong?!

“This is not a Tokmark installation!”

Fang Xu shouted in surprise!

A smile appeared in the corner of Lu Yongchang's eyes.

He is worthy of being Academician Fang, but he can't hide it from him!

"This is certainly not a Tocmak device!"

"This is a star-like device."

Lu Yongchang chuckled and said, "If my calculations did not make any mistakes, the controllable nuclear fusion time of iter should be within 30 minutes, right?"

Fang Xu's eyes moved slightly and he nodded slightly: "That's right, the latest experimental result has maintained the fusion reaction for about 26 minutes."

"Does it mean..."

"Haha..." Lu Yongchang smiled faintly: "If nothing unexpected happens, iter will soon touch the ceiling of the Tokmak installation!"

Fang Xu's pupils shrank suddenly: "You mean... the Tocmak device is not the optimal solution to achieve controllable nuclear fusion?!"

Lu Yongchang nodded and affirmed Fang Xu's statement.

"How is it possible...If this is the case, wouldn't humanity have been moving forward for decades on the wrong path?!"

Fang Xu stood there blankly and muttered to himself.

He was a little unable to accept Lu Yongchang's statement!

Lu Yongchang naturally knew Fang Xu’s complicated mood at this time.

In his previous life, in order to break the monopoly, all the scientific research forces in Xia Kingdom were invested in the research and development of the Tokmak device!

However, no matter how hard you try, the maintenance time of controlled nuclear fusion cannot exceed thirty minutes!

At that time, this was a fatal blow to all scientific researchers!

If Fang Xu hadn't learned about the defects of the Tokmak device by chance, Xia Guo would have made a mistake on the road to achieving controllable nuclear fusion!

"I...how do I verify your statement?!"

Fang Xu is worthy of being the top scientist in Xia Kingdom at present. After a brief loss of mind, he immediately reacted and asked Lu Yongchang in a deep voice.

Lu Yongchang shrugged and said with an understatement: "It's very simple. You just need to find the most basic imitation device, use the material I deduced to build a reactor, and then ignite the nuclear fusion, which can naturally be verified.

”

Fang Xu's eyes moved slightly.

He remembered that there was indeed an "outdated" star-like device in the laboratory that I bought for a lot of money.

"etc!"

Hong Qiming's loud voice suddenly rang aside.

"You...who will explain to me what do the stellar device and the tocmak device mean?"

While speaking, Hong Qiming turned his gaze to Lu Yongchang.

Guan Hualiang and Fang Xu, who saw this scene, took a step back and handed the stage to Lu Yongchang.

Lu Yongchang pondered for a moment and said, "Hongbu, you should be clear that controlled nuclear fusion requires a powerful magnetic field to constrain nuclear fusion materials, right?"

Seeing Hong Qiming nodding, Lu Yongchang breathed a sigh of relief.

This is easy to explain!

Otherwise... he also needs to explain the principle of controlled nuclear fusion from scratch!

Although it can be solved by a few words, it is a bit troublesome!

"Simply put, the annular spiral magnetic cage of the Tokmak device requires plasma current, which is not required by the satellite device. It can directly generate a twisted annular magnetic cage through the external coil."

"Then... are there any difference between these two? Don't they both generate magnetic fields?"

Hong Qiming's eyes showed a hint of confusion.

"Bang!"

Lu Yongchang snapped his fingers gently.

"That's what I'm going to say!"

"In the Tokmak device, the plasma current is as high as tens of millions of amperes. Such a huge current will inevitably bring countless problems."

"For example, twisting mode, magnetic surface tearing, magnetic island generation, etc."

"All of this will reduce people's ability to restrain plasma."

"The consequences are caused, at the least, the fire will be shut down, and at the worst, the explosion will be explosion!"

While talking, Lu Yongchang made an explosive gesture.

Hong Qiming nodded in a vague way.

Although he did not understand the various professional terms that Lu Yongchang said, he understood the last sentence.

What if the Tokmak device is placed on it explodes?!

Hong Qiming looked at Academician Fang Xu standing next to him with a complicated look on his face.

Facing Hong Qiming's gaze, Fang Xu had to nod helplessly and said, "This possibility exists, but... As of now, the Tokmak device has not had such a serious failure!"

"Not now, what about the future?" Lu Yongchang said in a faint tone, "When the fusion maintenance time is increased to 30 minutes, maybe serious consequences will occur!"

Fang Xu's body suddenly froze and exclaimed in a burst of voice: "You mean, the Tokmak device will explode after thirty minutes of fusion?!"

Lu Yongchang nodded with a complicated expression: "Yes, this is also the biggest trap of the Tokmak device."

"Although the polar magnetic field formed by plasma current makes the structure of the magnetic cage very simple, high temperatures and super-large currents will eventually lead to some unexpected occurrences."

Fang Xu suddenly realized: "So that's it! So that's it!!"

"Where is the imitation star weapon?" Hong Qiming swallowed slightly and asked in a low voice.

He suddenly felt that the young sophomore student in front of him was like an old professor who had been immersed in it for decades!

Even Fang Xu is like a student in front of him!

Hearing Hong Qiming's question, Lu Yongchang said lightly: "The imitation device is simple. You only need to create a closed and twisted ring magnetic cage inside through the external coil!"

Hong Qiming: "????"

"That's so simple? Then why didn't I use a star-imitation device before?!"

Fang Xu glanced at Lu Yongchang in anger and explained again: "The difficulty of imitation star instruments is the manufacturing of 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 sufficiently powerful magnetic field, the material of the coil is best to use a superconducting coil, which makes it more difficult."

"After all, there is no breakthrough in room temperature superconducting technology yet."
