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

"click..."

The sound of the office door opening immediately attracted the attention of everyone in the laboratory.

"Yongchang, you can figure it out!"

Fang Xu's eyes lit up, and he took the lead to greet Lu Yongchang: "How is it, have you solved it?"

Lu Yongchang raised his head, shook the draft paper in his hand, and nodded slightly.

"Hey! You have dark circles under your eyes!" Fang Xu was startled the moment he saw Lu Yongchang's face, "You haven't slept for three days?"

Fang Xu's reaction obviously startled Lu Yongchang too.

The movement in his hand stopped suddenly, and he subconsciously raised his hand to touch around the eye sockets: "It can't be so exaggerated... I have slept for 10 hours in the past three days!"

Fang Xu's expression became strange: "...10 hours?"

"Okay, you should go to sleep first!"

"At that time, if you die suddenly because of this, Chairman Li will not peel off my skin?!"

Lu Yongchang waved his hands indifferently: "Don't worry, I'm fine."

"Do the experiment first, we don't have so much time to waste!"

Seeing Lu Yongchang's appearance, Fang Xu had no choice but to wink at the researcher beside him helplessly, and then sighed softly.

"Okay, you are the boss of the laboratory, you have the final say."

"Well, what do you want us to do?"

Hearing Fang Xu's question, Lu Yongchang subconsciously turned his head to look at the reaction container placed aside.

He frowned slightly, and shook his head slowly: "No way! You need to change the container!"

"Contact the factory, we need to order a special container!"

Fang Xu frowned when he heard this.

"Order a container?"

"It will take a lot of time... What kind of solution are you going to use, I will tell the factory in advance."

While talking, Fang Xu picked up a paper and pen from the side to record Lu Yongchang's request for the container.

"Liquid Lithium."

Lu Yongchang's faint words echoed in the laboratory.

The movements in Fang Xu's hands stopped for an instant.

The next moment, he raised his head abruptly, looked at Lu Yongchang in front of him in horror and exclaimed.

"what?!"

"Liquid Lithium?!"

"This... this is too dangerous!"

You know, lithium is the most mobile metal among known elements!

Therefore, the danger of lithium element is extremely high!

If you are not careful, it will burn, and then cause an explosion!

Chapter 54 The Testing Machine Comes Out

Fang Xu looked at Lu Yongchang in front of him with a complicated expression, and the ballpoint pen in his hand trembled slightly.

Solid lithium is still dangerous, let alone liquid lithium heated above 180.54°C!

Now, Lu Yongchang actually told him to use liquid lithium as the reaction solution for controllable nuclear fusion? !

That's nuclear fusion!

The most violent reaction in the entire galaxy!

Not only Fang Xu, but all the researchers and professors around turned weird when they heard that liquid lithium was used as a solution.

"Cough cough..."

"Professor Lu, how about...let's think about it again?"

Lu Hezheng on the side cleared his throat and persuaded him in a nice voice.

Lv Yongchang glanced around, and after seeing the faces of the people, a bit of a wry smile appeared on his face.

Well, to be honest, he also felt that this solution was not very safe.

But which of the experiments related to nuclear physics is really safe?

Lu Yongchang pondered for a moment, then walked to the demonstration whiteboard beside the laboratory.

He reached out to pick up the black marker pen on the side, and wrote a series of complex and beautiful calculations on it.

"Guys, this is a mathematical model of the phenomenon of sonoluminescence."

"To ignite nuclear fusion in a solution, we must make the temperature of the bubble collapse reach hundreds of millions of degrees Celsius!"

"And this, only liquid lithium can achieve!"

As he spoke, Lu Yongchang quickly waved his right hand and wrote down the detailed calculation process on the whiteboard.

Fang Xu looked thoughtfully at the calculation formula on the demonstration whiteboard, and nodded slightly.

As one of the top academicians, Fang Xu quickly caught up with Lu Yongchang's explanation and came up with the answer.

He sighed softly, and said helplessly: "If the mathematical model is correct, then liquid lithium may really be our only choice."

Lu Yongchang chuckled: "In my opinion, liquid lithium is not a choice of desperation."

"On the contrary, it is the best choice for small fusion reactors!"

While talking, Lu Yongchang wrote down a symbol heavily on the whiteboard.

Li-6!

The moment he saw this symbol, Fang Xu's pupils shrank suddenly!

He got it!

He understands everything!

"Yongchang, are you planning to use the physical properties of lithium-6!"

There was a flash of excitement in Fang Xu's eyes, and he subconsciously stretched out his right hand and rubbed his nose vigorously: "Yes! Yes! You are right!"

"Liquid lithium is the best choice for small fusion reactors!"

Seeing the excited Fang Xu, a smile flashed in Lu Yongchang's eyes.

As expected of Fang Xu!

Got the point right the first time!

Unlike Fang Xu, all the researchers and professors around looked at Lu Yongchang with confused faces.

Naturally, Lu Yongchang didn't hold back for too long, and directly opened his mouth to explain.

"The lithium-6 atom has a physical property that is easily overlooked."

"When bombarded with neutrons, it releases tritium atoms."

Hearing Lu Yongchang's explanation, the expressions on everyone's faces were suffocated!

That's it!

Once the deuterium-tritium fusion reaction is triggered, it will naturally release a large number of neutrons!

After these neutrons bombard the surrounding liquid Li-6, the liquid Li-6 will release a large number of tritium atoms!

In this way, compared with the Pangu No. [-] fusion reactor, the small fusion reactor does not even need to replenish tritium gas, and only needs to replenish the cheapest deuterium gas regularly to maintain the operation of the fusion reactor for a long time!

"Yongchang! I'm going to contact the factory now!"

Fang Xu said excitedly: "I didn't realize it just now, but now it seems that this is simply the best solution to the miniaturization of fusion reactors!"

……

three days later.

In an open space 1000 meters away from Xia Guo's first laboratory, a huge iron factory building was erected out of thin air.

In the center of the factory building, there is a dark cylindrical container.

The container is approximately two meters high and approximately one meter in diameter.

At the bottom of the container is a huge ultrasonic generator.

This seemingly simple container is a test machine for small fusion reactors.

Looking at the device in front of him, Lu Yongchang's eyes flashed a bit of regret.

It has to be said that after gathering most of Xia Guo's resources, the progress of the experiment has been accelerated without limit!

Three days ago, Fang Xu had just contacted the factory. In just one hour, the blueprint of the test machine for the small fusion reactor was placed in front of Lu Yongchang!

Next... Not only did Xia Guo complete the manufacturing of the test machine within three days, even, for safety reasons, Xia Guo also specially built an iron factory building on the open space to serve as a temporary experimental site.

"Yongchang, when will we start the experiment?"

Fang Xu turned his head to look at the testing machine in the center of the workshop, with a flash of fire in his eyes.

This is a small fusion reactor!

As a top academician in the field of nuclear fusion, Fang Xu knows the gold content of this stuff better than anyone else!

Unlike large fusion reactors, small fusion reactors will not be used in the civilian field, it will only shine in the military field!

Fang Xu's heart began to beat violently when he thought that Xia Guo's aircraft carriers, submarines or fighter jets would all use nuclear fusion as energy in the future!

"No rush, we'll wait for someone first."

Lu Yongchang's faint words came from the side.

"Wait someone?"

Fang Xu was taken aback for a moment, and subconsciously asked, "Who are you waiting for?"

Lu Yongchang looked past Fang Xu and looked into the distance: "Here, here we come!"

Fang Xu turned his head quickly and looked in the direction Lu Yongchang was looking at.

I saw a black red flag car slowly driving towards the location of the iron factory building.

The license plate number, of course, is that familiar string of numbers.

"The chairman is here?!"

Fang Xu was taken aback and exclaimed softly.

"Let's go!" Lu Yongchang straightened his clothes, "It's time for us to greet him!"

……

"so small?!"

"Yongchang, are you sure this thing can undergo controlled nuclear fusion?!"

As soon as he saw the test machine, Mr. Li questioned Lu Yongchang.

Faced with doubts, Lu Yongchang naturally responded with a smile: "Chairman, this thing does not depend on size!"

"It's just a test machine now. If it succeeds, it can be made even smaller!"

"At that time, it will be no problem to install it on your car!"

Councilor Li smacked his lips, obviously not particularly convinced by Lu Yongchang's words: "The power generation of this thing should not be comparable to Pangu No. [-], right?"

Lu Yongchang's expression suffocated suddenly.

Is not this nonsensical? !

What is Pangu No. [-]? !

Just covers an area of ​​20 square kilometers!

How big is this small fusion reactor?
