God-level selection: choose the college entrance examination full score at the beginning

Angry questioning from the five largest technology companies in the United States

The temperature at which a superconducting material changes from a normal state to a superconducting state (or vice versa) when the external magnetic field is zero, expressed in Tc. Tc value varies with different materials. The lowest Tc of the superconducting material that has been measured is tungsten, which is 0.012K.

This tc value is basically equivalent to the performance of superconducting materials.

However, the highest tc value of the superconducting materials discovered by humans is only 164k. This is a performance that can only be achieved in the laboratory, and can only be achieved in an extremely low temperature or high pressure environment.

Under the conditions of normal temperature and pressure, there are only a few kinds of materials that can maintain superconducting properties, and not many of them can reach 10k or more.

And the new material in the document that Cheng Hao gave them in front of them can actually reach the superconducting performance of 180k under normal temperature and pressure.

What does this mean? ?

It means that if this material is used to make cablesIf so, there may even be no current draw at all.

Completely zero resistance!

And it’s extremely antimagnetic!

In many fields of engineering, this material is simply invincible!

At this time, Professor Hua and Professor Lin next to him also looked at Cheng Hao with incredible expressions in their eyes.

Cheng Hao smiled, looked at the three professors in front of him and said: “Everyone, this is just the performance I made in the laboratory, but I don’t know how difficult it is to produce this material in engineering?? Can’t build a machine to produce that material?”

“We have to discuss it!”

Professor Lu pondered for a while, looked at Cheng Hao in front of him and said.

“it is good!”

Cheng Hao nodded.

Next, the three professors around started arguing, discussing what method should be used to start producing this new material, and what method can save costs.

What kind of machinery should be used to produce it.

Cheng Hao listened to the arguments of several professors with relish. Although he didn’t have much experience in engineering, it didn’t prevent him from being able to understand some engineering things of these professors in front of him.

After all, you know, his IQ has reached 265!

It’s not that I don’t understand.

Soon, the professors in front of them basically argued for a result, but this result stunned them all.

“It can be produced…”

With a hint of hesitation in his eyes, Professor Lu looked at Cheng Hao in front of him and said.

“And the cost is not high, right!”

Cheng Hao smiled slightly, looked at Professor Lu in front of him and said.

“Did you understand?”

With a hint of surprise in his eyes, Professor Lu looked at Cheng Hao in front of him and said.

“En! It’s not too difficult to understand, your words!”

“It’s really not difficult to make. It’s not very difficult in engineering. We can even quickly draw a machine for making materials!”

With a smile on his face and admiration in his eyes, Professor Hua looked at Cheng Hao in front of him.

“Professor Cheng, this material of yours is about to change the world!”

With a hint of emotion in his eyes, Professor Hua looked at Cheng Hao in front of him and said.

Cheng Hao smiled slightly and didn’t say much.

He also showed a strong look of surprise in his heart.

I really didn’t expect that the cost of this iron-based graphene superconducting material would be so cheap!

Judging from the price of making wires, the price per meter does not exceed 30 yuan!

Even the price of ordinary infrared optical fiber can exceed fifty or sixty yuan!

But the cost of this superconducting material is only 30 yuan…

This price is really too cheap!

It’s unbelievably cheap…

Cheng Hao was also surprised.

“Okay! Then I will trouble you, professors, to design the process flow and material production machinery for this superconducting material!”

Cheng Hao smiled slightly, and said to the three professors in front of him.

The three professors all nodded.

When several professors started to design the machine during the discussion.

Cheng Hao has already walked out of the office.

He came to the chairman’s office of Yinhe Technology, which he had almost never been to.

Walking into the office, Cheng Hao dialed Wang Tian’s number without the slightest hesitation.

“Hey?”

Wang Tian’s voice came from the other end of the phone.

“Big Brother Wang Tian, ​​it’s like this.”

Cheng Hao basically talked about the development of superconducting materials by himself, and then asked several professors to develop the process.

There was silence on the other end of the phone for a while.

“I understand what you mean, don’t worry, this superconducting material will definitely not be leaked!”

Cheng Hao was slightly relieved after hearing what the boss Wang Tian said.

With the words of Mr. Wuyou, the safety of this material can be truly guaranteed!

“Thank you!”

Cheng Hao was about to thank the boss Wuyou, but at this time the boss Wang Tian had already thanked Cheng Hao in advance, which made Cheng Hao slightly stunned.

“You’re welcome!”

Cheng Hao showed a smile on his face, and hung up on the words of the boss Wang Tian.

After sitting in the office for a while, Cheng Hao returned to the office next to him.

The three professors basically discussed the technological process and mechanical design.

Yinhe Technology has its own factory building.

With the full cooperation of the technicians, they quickly completed the preliminary drawing of the machine, and then began to try to manufacture the machine. It was necessary to build a smaller production line first to see what the success rate was and what the yield rate was.

After all, on the production side, the yield rate represents the cost. If the yield rate is too low, it basically means that there is a problem with the process and needs to be improved.

The production line of superconducting materials here is still being debugged.

And the other time, the deal with the Planck Nuclear Physics Laboratory is in progress.

This transaction should have been done by Cheng Hao himself.

But now Cheng Hao’s identity is a bit sensitive, so Cheng Hao specially asked an employee of Yinhe Technology and an official of the government to go.

This transaction is completed.

Naturally, such a transaction cannot be done silently, before the retired stellarator Weag arrived in China.

The five major technology companies in the United States have already exploded.

Didn’t your company say before that this technology can no longer be traded to other entities? ? ?

Well, just after I finished talking, Yinhe Technology has reached this deal with Germany’s Max Planck Physics Laboratory!

The anger of these technology companies was instantly ignited.

of these technology companiesDelegates, gather in the guest room.

“We need an explanation!”

“Money back!!”

Several representatives were obviously very angry.

The reception staff of Galaxy Technology on the side kept calming the emotions of several people.

It happened that Cheng Hao walked into the reception room.

“Refund?”

When Cheng Hao heard this, a smile appeared on his face.

“It is impossible to refund the money!”

“you!”

Several representatives of the five major technology companies around showed angry expressions on their faces, staring at Cheng Hao in front of them.

“What do you mean???”
