It's reasonable for me to have a two-way foil for a second-level civilization, right?

This is not to say that learning can be learned!

At least, he can't.

Not to mention him, even among the academicians of the Academy of Sciences, it is estimated that there are not many people whose drawing skills can reach this level!

In the office, it gradually fell into silence.

Except for the breathing of the two, there was only the "rustling sound" of the pen in Lu Yongchang's hand scratching the white paper.

"This is……"

Fang Xu raised his eyebrows sharply.

With the gradual improvement of the drawing lines, he could see what Lu Yongchang was drawing!

"Magnetic fluid generator?"

Lu Yongchang didn't stop what he was doing, chuckled, nodded and said, "That's right! It's a magnetic fluid generator!"

"In my opinion, this is simply the most suitable device for controllable nuclear fusion, bar none!"

Fang Xu frowned instantly.

After pondering for a moment, he said with a heavy tone: "Yongchang, I know that the power generation efficiency of the magnetic fluid generator is very high."

"But...the magnetic fluid generator has several fatal flaws, and this technology is not yet mature enough!"

"Isn't it a bit... too reckless to use it rashly for controllable nuclear fusion?"

The pen in Lu Yongchang's hand stopped abruptly.

He slowly looked up at Fang Xu, smiled and shook his head: "Difficult?"

"Currently, there are two difficulties that limit the magnetic fluid power generation technology."

"First, magnetic fluid power generation technology requires inert gases containing trace amounts of alkali metals such as potassium and cesium as working fluids."

"Second, the high temperature environment under the normal operation of the magnetic fluid generator."

"Am I right?"

Fang Xu's eyes narrowed slightly, and he nodded lightly: "This is the first one, and it is still difficult to solve it now."

"Mass production of noble gases, this technology, we don't have yet."

"According to the current technical means, if a magnetic fluid generator is used, even if the working fluid can be recycled, the cost will far exceed our expectations!"

Lu Yongchang stared at Fang Xu meaningfully, with a faint smile in his eyes.

"Brother Xu, are you sure, we don't have the technology to make inert gas yet?"

Fang Xu frowned slightly, and after carefully recalling in his mind, he slowly shook his head: "I'm sure, at least as of last week, I haven't seen related technologies in Xia Guo, or even international journals! "

Lu Yongchang didn't speak, but took a deep look at Fang Xu, and then picked up the pen to write and draw on the paper again.

Seeing this scene, Fang Xu frowned even deeper, and an inexplicable sense of irritability came from the bottom of his heart.

Vaguely, he had a premonition.

I seem to have overlooked an extremely important thing!

But Fang Xu couldn't figure out what it was.

"Yongchang?"

Fang Xu's eyes showed a bit of anxiety, and he asked in a low voice to Lu Yongchang in front of him: "What kind of technology is it? Tell me quickly!"

Lu Yongchang still didn't speak, just tapped the desk with the tip of the pen.

Fang Xu, who was attracted by Lu Yongchang's actions, looked down at the white paper in front of him.

A line of neat pen writing appeared on the white paper.

1 2 H+ 1 3 H→ 2 4 He+ 0 1 n+17.6MeV

This is... the reaction formula of deuterium-tritium fusion!

Seeing the extremely familiar reaction in this line, Fang Xu immediately froze in place.

His lips trembled slightly, and a smile gradually appeared on both sides of his cheeks.

"So it is! So it is!"

No wonder he always felt like he was neglecting an important thing!

Considering all the external factors, he just ignored the most important internal factors!

Different from ordinary thermal power generation and nuclear fission power stations, deuterium-tritium fusion itself produces helium!

Hydrogen-2 and hydrogen-3 undergo fusion reactions under high temperature conditions to produce helium-4 and neutrons. This is simply the knowledge of high school physics, but...he, an academician, just ignored it!

Fang Xu smiled wryly and shook his head: "In this case, the first difficulty has been solved."

The smile in Lu Yongchang's eyes became more obvious: "The second difficulty, is it still difficult for us now?"

Fang Xu froze for a moment, then suddenly reached out and patted himself on the head!

"Oh! My brain! What happened to this recently!?"

The new material in the stellarator reactor can resist the high temperature of controllable nuclear fusion. Could it be said that it cannot resist the "low temperature" of 2000-3000K when the magnetic fluid generator is working?

The more Fang Xu thought about it, the more excited he became. He turned his hands behind his back and kept circling around Lu Yongchang's office.

"exactly!"

"Helium can be produced in the deuterium-tritium fusion reactor! It is still a high-temperature gas of hundreds of millions of degrees Celsius!"

"We don't even need to expend energy to heat it up!"

"This is simply, this is simply the perfect power generation solution!"

Lv Yongchang chuckled, and handed the sketch on the table to Fang Xu: "Brother Xu, let's see if Sandaokou University has any talents in this field. If so... make a prototype as soon as possible!"

"Let's strive to complete the first controllable nuclear fusion demonstration reactor within half a year!"

Fang Xu was in a turbulent mood, reached out to take the sketch handed over by Lu Yongchang, and nodded vigorously!

"it is good!"

"Don't worry, leave this matter to me!"

"I promise, within two months, you will be able to see the prototype of the magnetic fluid generator!"

Chapter 29 Approval of the Project

Two days later.

One ring of the capital.

Looking at the quaint buildings in front of him, Lu Yongchang's eyes showed a bit of regret.

"Let's go, Mr. Li is waiting for you!"

Seeing Lu Yongchang stop, Hong Qiming hurriedly urged: "By the way, what you asked to prepare, are you ready?"

Lu Yongchang smiled and nodded, shaking the briefcase in his hand.

"Isn't it just a budget statement? It's been prepared a long time ago."

Hearing this, Hong Qiming breathed a sigh of relief: "That's good."

"I won't accompany you in this time, you have to deal with everything by yourself."

"Remember, calm down, and don't say unrealistic things like last time!"

Lu Yongchang nodded helplessly.

……

"Tuk Tuk Tuk!"

Standing in front of the heavy wooden door, Lu Yongchang took a deep breath, raised his hand and knocked on the door lightly.

"come in."

A short, forceful voice came from inside the door.

"Squeak..."

As soon as he opened the door, Lu Yongchang saw Mr. Li sitting behind his desk, looking at him with a smile on his face.

"Yongchang, you gave me a surprise!"

Councilor Li stood up with a smile and walked to Lu Yongchang.

"sit down!"

Councilor Li took the lead and sat on the sofa beside him.

Lv Yongchang pondered for a moment, did not refuse, and sat down across from Mr. Li.

"Next, what are you going to do?"

Without any polite words, Mr. Li asked directly.

Hearing Mr. Li's question, Lu Yongchang did not hesitate at all, and said directly: "I suggest that the controllable nuclear fusion demonstration reactor project be launched immediately!"

Mr. Li frowned slightly.

"Demonstration pile? So fast?"

Lu Yongchang nodded lightly: "At present, we already have relatively mature controllable nuclear fusion technology. I think this is an opportunity."

"Opportunity?" Councilor Li raised his eyebrows slightly, and looked at Lu Yongchang in front of him with interest.

"That's right, a chance to catch up with the United States!"

"One, a chance for Xia Guo to take off again!"

Lu Yongchang's eyes flickered, and he said word by word!

Councilor Li's pupils shrank suddenly.

He stared at Lu Yongchang meaningfully, and said softly: "When we met last time, you also said similar things."

"Didn't Hong Qiming tell you to be more calm? Don't say anything that is unrealistic."

Lu Yongchang looked solemn and shook his head slowly.

"Minister Hong reminded me."

"But... In my opinion, if you don't even dare to have such an idea, Xia Guo will never be able to catch up with Mi Guo!"

"Perhaps in your opinion, controllable nuclear fusion is just a better power generation device, which can bring inexhaustible and low-cost energy to Xiaguo, am I right?"

Councilor Li fell silent.

After a long time, he asked again, "Could it be, isn't it?"

"of course not!"

Lu Yongchang was a little excited.

"Controllable nuclear fusion means the key to a new era!"

"This new era refers to the interstellar era!"

"With controllable nuclear fusion as an energy source, we can look farther!"

"The moon, Mars, and even the entire solar system!"

"Xia Kingdom, which has nuclear fusion as an energy source, can take the lead in marching into space!"

Seeing Mr. Li's expressionless face, Lu Yongchang became ruthless, and made a big splash!

"I already have some ideas about the fusion reactor miniaturization project."

"If it succeeds, Mr. Li, think about it, our aircraft carrier, submarine, or fighter plane, have the scenario of nuclear fusion as an energy source!"

Now, even Congressman Li can't keep calm!

With a bang, he stood up directly from the sofa, staring at Lu Yongchang in front of him with burning eyes!

"What you said is true?!"

Facing Mr. Li's scorching gaze, Lu Yongchang's heart beat violently several times.

Originally, in his plan, there were no such words.
