In February, snow falls in Jinling, and it is about to be the New Year.

These days, Lu Zhou has almost lived in a laboratory.

Although I bought a house, I haven't been back to live there a few times, which is a pity.

But fortunately, a few days before the new year, the research work at hand was finally completed, and this also made him breathe a sigh of relief.

In fact, this work does not have to be done before the New Year.

However, being able to accomplish this achievement at this time can still add some leverage to his trip to Germany.

In any case, a stellar simulator is necessary in order to carry out subsequent research.

Politely worded an email and sent it to Professor Kreber in Germany, Lu Zhou changed into his coat and left the institute.

After coming out of the research institute, he took a breath of fresh air outside, and before going home, he stopped by the construction site of the STAR Stellarum Research Institute.

The cold did not freeze the enthusiasm of the workers, as when the project first opened, the construction site was in full swing.

Almost every time he passes by here, Lu Zhou can feel that it is different from the last time.

With the support of ten times the manpower and material resources, the progress of the project is advancing at a speed visible to the naked eye in days.

happened to be patrolling the scene and noticed Lu Zhou getting off the car, Dai Tuan walked over in a meteoric stride and greeted him with a smile.

"What wind brought you here?"

Lu Zhou: "I was about to go home, and I happened to pass by here, so I stopped by here and went around." It's about to be the New Year, thank you for your hard work. ”

Head Dai said nonchalantly: "It's okay, what's this hard work?" ”

The project is not accepted, and the oath meeting is not held.

For this year's New Year's dinner, they never planned to eat outside the construction site from the beginning.

After a few words of greeting with Lu Zhou, and looking at the research institute under construction not far away, Head Dai squinted his eyes and said with some fascination: "You say that if our country uses electricity from controlled nuclear fusion, how much money can be saved in energy every year?" ”

"I'm not winning the Nobel Prize in Economics, so I'm afraid I can't give you an accurate number."

As a joke, Lu Zhou paused for a moment and continued, "But one thing is for sure, when the day comes, our country's electrical industry will usher in a leap forward." ”

Although Lu Zhou has no research on economics, his intuition tells him that the value of this is not something that can be measured in money.

Captain Dai: "Leap? Like changing that time? ”

Lu Zhou said in a joking tone: "It's hard to say, maybe it's the industrial revolution." ”

The Industrial Revolution......

That sounds like a distant word.

Even in the history of human civilization, there have only been three occurrences.

Looking at the building not far away, Captain Dai's eyes couldn't help but look forward to it a little more......

……

The snow in Jinling came and went fast, and it stopped after a while.

For the vast majority of cities in northern Europe, it was still a snow-soaked scene.

On the corner of Baltic Bay, on the outskirts of the quiet town of Greifswald, Kreber sits in the Spiral Rock 7-X lab, checking his work email.

Just as he had finished processing all the unread emails, another unread email suddenly flew into his mailbox.

I clicked on the email, and when I saw the sender, Kreber was slightly stunned.

Lu Zhou?

After seeing the name, Kreber's expression straightened slightly, and he continued to look down the body of the email.

[Hello, dear Professor Kreber.] 】

[In a few days, it will be the New Year of Huaguo, and at this auspicious moment, I sincerely wish you good health and all the best. 】

[In addition, I have good news here, I believe you will be interested......]

Reading this, Professor Kreber's eyebrows raised, and a look of interest immediately appeared on his face.

If someone else had said this, he might not have believed it.

But this was said by Lu Zhou, even if he didn't know what he was going to say, he couldn't help but look forward to it.

【…… In order to improve the problem of insufficient confinement magnetic field strength, we tried many schemes. And in the end, we succeeded with a carbon-based superconducting material. 】

[You know, among the many engineering problems that restrict the increase in the strength of electromagnetic fields, one of the most critical is that it is difficult to continue to expand the size of the coil while ensuring that the copper oxide conductor is at the superconducting transition temperature. After all, whether it is the copper oxide material or the channel through which it transports liquid helium, the volume occupied in the entire superconducting magnet engineering is not small. 】

[In order to solve this problem, we have made many attempts, the most considered of which is to increase the transition temperature of the superconducting material as much as possible, so that it is as close to room temperature as possible, so as to reduce the volume occupied by the cooling device in the whole project. 】

[In fact, because of this experimental idea, we have indeed achieved a lot of results.] However, at this moment, we unexpectedly discovered that in order to solve this problem, we do not necessarily have to start with the temperature transition. 】

[Taking copper oxide materials as an example, one of the most important difficulties to overcome in order to maintain copper oxide conductors under the condition of superconducting transition temperature is the poor thermal conductivity of copper oxide. It's just not friendly enough. 】

[As a superconducting material, graphene has excellent properties in transverse heat soaking and longitudinal heat dissipation, and the thermal conductivity can even reach 5300/m·k in theory.] 】

[You're an engineer, so you should know exactly what this means.] 】

Originally, he was reading this letter very seriously, but when he saw this, Kreber smiled and shook his head.

Of course, he knows what this means, even if the thermal conductivity of SG-1 material is not as exaggerated as 5300/m·k, more than 1,000 thermal conductivity is enough to completely detonate copper oxide with poor thermal conductivity.

You know, even if it is pure copper, the thermal conductivity is only 401/m·k.

What does this mean?

This means that in an engineering sense, if the difficulty of keeping copper oxide at the superconducting transition temperature is 10, then the engineering difficulty of keeping the graphene conductor at the superconducting transition temperature is only 1, and may not be even less.

In fact, in some cable materials or electronic devices, graphene itself is used as a heat sink that is more advanced than graphite.

However, the problem is that the superconductivity of SG-1 material is reflected in the overlapping angle of two-dimensional materials, how do you plan to process SG-1 material into wires?

It's not as simple as pancakes.

At least Kreber himself couldn't figure out how to turn that kind of thing that appeared in the lab into wires.

Not to mention, the price......

However, at this moment, he was reading the email, but he was suddenly stunned.

I saw that at the end of the email, Lu Zhou wrote-

【…… In fact, we've managed to find a way to do it. Even though it may not seem so reliable, we've managed to get a half-meter length of wire. 】

Slumped to his feet, and Kreber almost fell out of his chair.

Noticing the situation here, his assistant hurriedly asked, "What's wrong, Professor?" ”

"It's nothing," Standing firmly on the armrest of the chair, Kreber straightened his collar a little embarrassed, and then looked at his assistant, "Help me book a plane ticket, I'm going to Jinling, Huaguo." ”

The assistant was slightly stunned and turned the pen in his hand.

“…… What? ”

Without any hesitation, Kreber said with a serious face.

"Now, or as soon as possible!"
