Chapter 117 Choose one from three
The next night, Fu Jiangshui came to the multi-function hall as scheduled.He noticed that there were guards standing at the door, and an additional identity verification checkpoint was set up. Obviously, the content of this meeting was different from the past.

Entering the hall, there were already about thirty people sitting inside. They were obviously all top experts in various fields, and Fu Jiangshui had even seen photos of many of them in news reports or scientific magazines.

However, to his surprise, the multi-function hall actually activated a video projection screen. Through the projection screen, he could see that the camera on the other side was facing the leader's office.

There is nothing strange about online conferences, but it is very strange to put them in the comprehensive prevention and control center.

There are forbidden network areas everywhere here, and only a few areas allow Unicom to connect to the external network.

The number of seats was not marked on the seat, Fu Jiangshui turned around, and decided to sit next to Gao Wei after seeing Gao Wei also came - anyway, the other party was at least an acquaintance.

"You are here, there is no one here." Gao Wei greeted him warmly when he saw him.

"Thank you, I saw you just as I was planning to find someone to be my companion." Fu Jiangshui pointed to the screen curiously after sitting down, "Can I access the Internet here?"

"No. But this meeting uses special communication equipment, which is not based on the existing network." Gao Wei explained, "I don't know the specific technology, it seems to be related to quantum encryption communication, and now it is two quantum satellites that provide us with communication links."

He wondered, "It's just a video conference, is it necessary?"

In my impression, this technology was developed for the military. It focuses on anti-interference and anti-eavesdropping, and it is only useful in the complex electromagnetic environment of the battlefield.

Now that both parties to the meeting are located in the country, a maximum of one dedicated line can be set up to meet the extremely high confidentiality requirements. Using satellites feels a bit unnecessary.

He really couldn't figure out what the higher ups were guarding against.

"This is just the beginning. In the future, the prevention and control center will distribute special portable communication encryption equipment to replace our mobile phones. In this way, everyone can easily communicate even in the facility." Gao Wei suddenly lowered his voice when he said this, "The meeting has begun."

After an opening speech by several superior leaders, the moderator finally brought the meeting to the topic.

"Currently, the three project teams led by Professor Fu Jiangshui, Professor Han Weining and Professor Li Bai have conducted comprehensive research on the new type of ore. In addition to the reports on the general mechanical properties and chemical properties, the most gratifying discovery comes from Professor Fu's laboratory. I think everyone present at the meeting already knew in advance that this material has natural superconductivity."

"In order to commend Professor Fu Jiangshui's discovery, the higher authorities decided to adopt Professor Fu's proposal and give the new type of ore an official name: "Yaoshi". "

There was a burst of applause at the scene.

"Congratulations." Gao Wei whispered while applauding.

Fu Jiangshui smiled modestly, pretending to be calm on the surface, but he was already happy inside.For researchers, it is definitely a great honor to name something new, let alone such an important thing!
It was undoubtedly his best choice to initially agree to join this project.

"Next, the research on Yaoshi will enter a new stage—that is, the stage of engineering application." The host waited until the applause subsided before continuing, "Because this ore cannot be mass-produced temporarily, it is difficult for us to invest the same resources in every project. In order to maximize the use of Yaoshi, we must select a project as the main research direction, which is also the purpose of this internal meeting."

"Next, I will invite three experts to come on stage one by one and talk about their research plans. Finally, everyone will vote to select the most technically feasible and actually the best profit-generating plan, which will be the main goal in the coming year."

He held out his hand, signaling the first speaker to come on stage.

"Professor Wang, please tell us about his first plan. If you have any questions, you can raise your hand on the spot."

I see.Fu Jiangshui understood that this meeting will decide which engineering project the first batch of Yaoshi will be used in. This is somewhat similar to the laboratory's need for funds and samples, but it consumes much more resources.If the laboratory does not produce results, a few grams of samples will be wasted at most, and if this direction is chosen wrongly, the first-mover advantage and all the Yaoshi will be delayed, which shows its importance.

"Hi fellow experts, my research direction is the magnetic levitation ring, and the application path is the space elevator."

Professor Wang's explanation is quite simple and clear. Since superconductors also have complete diamagnetism, namely the Meissner effect, they can spontaneously levitate on magnets.If it is an electromagnet, it can also control the levitation height by changing the current intensity, which is also the principle of the maglev train.

And if a superconductor is used to make the levitation ring, its floating will not cause any loss, and it can always be suspended in the air.In this way, a suspension ring is set every few kilometers to form a floating orbit.And its inner ring is equipped with an accelerating magnetic field, which can launch an elevator like a coil gun, and the same is true for returning, only need to reverse the magnetic pole of the inner ring.

"Space elevators have always been the most feasible idea for people to go to near-Earth space with low loss. Compared with rail elevators fixed by carbon fiber bundles, superconducting maglev elevators have no rigid connection and are extremely resistant to damage. Even if the middle ring is damaged, it will not lead to the collapse of the entire elevator. What's more, there has been no feasible solution for the high-altitude operation and fixation of carbon fiber bundles. The construction of superconducting rings is much easier. Once it is put into practical use, we will have the advantage of space delivery that other countries cannot match. My team estimates that the transportation cost per ton is expected to be less than One hundred dollars, any launch vehicle from the ground will be meaningless."

Then someone raised his hand.

"Please tell me." Professor Wang nodded.

"It takes a lot of stones to make this kind of floating ring, right? Can the amount of mining keep up?"

"Only the upper and lower coils of the levitation ring need to use room-temperature superconducting materials. Of course, considering the size of the ring itself, it does use a lot of materials. About five to six tons of stones are needed for each ring. If the plan is approved, my team plans to make a test ring first to verify the carrying capacity of the space elevator. The remaining rings can be replenished when there are enough stones."

Then several experts asked questions one after another.

After no one raised their hands in the audience, the host invited the next researcher to come on stage.

"The second proposal was proposed by Professor Lu, and his proposal is a supercomputer."

Compared with the space elevator project, the consumption of supercomputer is much smaller.Due to the zero-resistance and non-heating characteristics of superconductors, the efficiency of the chip can be greatly improved without being affected by the power consumption wall, which reduces the manufacturing process of the chip in disguise and greatly improves the performance of the computer.

The reason for choosing a supercomputer is also very simple. At present, there is no secret formula for room temperature superconducting materials, so chips made with it cannot enter the private market. At the same time, superconducting chips do not replace ordinary metal materials with stones, and their structure must also undergo corresponding changes. Only supercomputing centers with national background can afford the corresponding reconstruction and use costs.Fortunately, the research on superconducting computers did not start from scratch. The project of combining superconducting and quantum computing has been done by a team ten years ago.

"I guess the higher-ups won't vote for Plan No. [-]." Fu Jiangshui said in a low voice.

"Oh? Why?" Gao Wei asked.

"The prospect is unclear, and the scale of benefits is not large. The only advantage is that the demand for Yaoshi is not high, so they can completely share it with them." He shook his head. Superconducting chips are not on the same track as ordinary high-end chips. Even if they are successfully developed, it will be difficult to regain the civilian market.

Even he can see this problem, it is impossible not to see it above.
