Chapter 483 Half a Meter of Wire

In February, there was snow in Jinling, and the New Year was coming soon.

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

Although I bought a house, I didn't go back to live in it a few times, which is really 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, these tasks do not necessarily have to be completed before the New Year.

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

In any case, in order to carry out follow-up research, a stellarator is necessary.

After politely editing an email, he sent it to Professor Kleiber 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 Stellarator Research Institute.

The cold did not freeze the enthusiasm of the workers at all. Just like when the project first started, the construction site is full of enthusiasm at the moment.

Almost every time he passed by here, Lu Zhou could feel that it was 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 units of days.

He happened to be patrolling the scene and noticed Lu Zhou who got off the car. Captain Dai strode over and greeted him with a smile.

"What brings you here?"

Lu Zhou: "I was about to go home. I happened to pass by here, so I stopped by here to make a circle. The Chinese New Year is coming soon, thank you for your hard work."

Captain Dai said indifferently: "It's okay, what's all this hard work?"

No acceptance of the project, no oath meeting.

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

After exchanging a few words with Lu Zhou, looking at the research institute under construction not far away, Captain Dai squinted his eyes, and said with some fascination: "You said that if our country uses controllable nuclear fusion Electricity, how much money can you save on energy every year?"

"I didn't win the Nobel Prize in Economics, so I'm afraid I can't give you an accurate figure."

Just kidding, Lu Zhou paused for a moment, then continued, "But one thing is for sure, when that day really comes, our country's electrical industry will usher in a leap-forward development."

Although Lu Zhou did not study economics, his intuition told him that the value cannot be measured by currency.

Captain Dai: "Feiyue? Like when it was changed?"

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

industrial revolution ah...

This sounds like a distant vocabulary.

Even in the history of human civilization, it has only happened three times.

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

...

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

For the vast majority of cities in northern Europe, it is still a scene covered in silver at this time.

Located at the corner of the Baltic Bay, on the outskirts of the quiet small town of Greifswald, Kleiber, sitting in the Helix 7-X laboratory, is checking his work email.

Just when he had just processed all the unread emails, another unread email suddenly flew into his mailbox.

He clicked on the mail, and when he saw the sender, Kleiber was slightly stunned.

Lu Zhou?

After seeing the name, Kleiber's expression straightened slightly, and he continued to read down the text of the email.

[Dear Professor Kleiber, hello. 】

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

【In addition, I have some good news here, I believe you will be interested...】

After reading this, Professor Kleiber raised his eyebrows, and a look of interest immediately appeared on his face.

If someone else said this, he might not believe it.

But it was Lu Zhou who said it. Even though 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 have tried many solutions. And finally, we succeeded with a carbon-based superconducting material. 】

[You know, among the many engineering problems that restrict the increase of electromagnetic field strength, the most critical one is that it is difficult to continue to expand the coil scale under the premise of ensuring that the copper oxide conductor is at the superconducting transition temperature. After all, whether it is the copper oxide material or the channel for transporting liquid helium to it, the volume occupied in the entire superconducting magnet project is not small. 】

[In order to solve this problem, we have made many attempts, among which the most considered is to increase the transition temperature of the superconducting material as much as possible, and make it as close to room temperature as possible, so as to reduce the cooling device's occupation in the entire project volume. 】

[In fact, because of this experimental idea, we have indeed achieved considerable results. But at this moment, we unexpectedly discovered that in order to solve this problem, it is not necessary to start with the transformation temperature. 】

[Taking copper oxide materials as an example, if you want to maintain the copper oxide conductor at the superconducting transition temperature, one of the most difficult difficulties to overcome is the poor thermal conductivity of copper oxide. It's just not friendly enough. 】

[Similarly as a superconducting material, graphene has excellent performance in both lateral heat soaking and longitudinal heat dissipation. In theory, the thermal conductivity can even reach 5300W/m·k. 】

[You are an engineer, you should know what this means. 】

Originally, he was seriously reading this letter, but when he saw this, Kleiber shook his head with a smile.

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

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

what does that 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 graphene conductors at the superconducting transition temperature is only 1, or even less.

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

However, the problem is that the superconducting properties of the SG-1 material are reflected in the overlapping angle of the two-dimensional material. How do you plan to process the SG-1 material into a wire?

It's not as simple as baking a lasagna.

At least Kleiber himself couldn't figure out how to process the stuff that appeared in the laboratory into wires.

Not to mention, the expensive price...

However, at this moment, he who was reading the email suddenly froze.

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

【...In fact, we have successfully found a suitable method. Even though it might not seem that reliable, we've managed to get a half-meter length of wire. 】

Sitting up suddenly, Creber almost fell off the chair.

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

"It's nothing." The armrest of the chair stood firm, and Kleiber straightened his collar in some embarrassment, then looked at his assistant, "Book me a plane ticket, I'm going to Jinling, Huaguo."

The assistant froze for a moment, then turned the pen in his hand.

"...what's the date?"

Without any hesitation, Creber said seriously.

"Now, or as soon as possible!"
