Infrastructure: Start to Repair The Elevator in Mount Everest

Chapter 289

Following Li Qi’s proposal, more and more experts and professors, as well as technical personnel involved in this project, all gathered.

Li Qi stood in the last row. He knew that he had no say in this matter.

It’s not in my own professional field, so I can’t point fingers at others.

Seeing that everyone was full, the designer in front shot three drawings on the summit stage with a projector.

Director Li turned his head and said, “Mr. Li, come forward.”

Li Qi hurriedly smiled and waved his hand: “No, no, no, experts are in front. I’d better not block the sight of experts.”

“I’m serious, you are the chairman of Yishan Reclamation, and you are responsible for this project.”

“I’m here today, only with ears. So what about the chairman, does it have a specialty in the field of surgery.”

Seeing Li Qi’s resignation, Director Li didn’t insist anymore. He immediately picked up the microphone and said, “Xiaohou, let’s start.”

Xiao Hou, who is the introducer of the design drawings, heard Director Li’s voice and quickly said:

“Everyone, this time we are here…”

Before he finished speaking, Su Mingyu interrupted: “Go straight to the subject, there is not much time left for us. Now the world is watching Tarim.”

Xiao Hou quickly said: “In the design drawing No. 1, we mainly adopted acoustic levitation technology. The car envelops the cable installation, and uses acoustic levitation technology in the middle to fix it on the cable, but does not touch the cable.”

“The reason why we adopt acoustic levitation technology is that the acoustic levitation technology can allow the car to leave the cable as far as possible. In this way, it can minimize or eliminate friction under high-speed kinetic energy. This technology is useful for The cable has a protective effect…”

The voice fell, and no one in the court spoke. Everyone looked at the other drawings blankly. Obviously, this No. 1 filing was directly ruled out by everyone.

Director Li is straightforward: “Let’s focus on the 2 and 3 filings.”

“Yes, Director Li.”

At this time, Li Qi looked at an expert next to him with some doubts, lowered his voice and asked, “Professor, let’s just eliminate the No. 1 plan. ‖?”

The old professor smiled kindly: “Yes.”

“Why?”

Li Qi was a little surprised: “I think what he said is very reasonable. It can reduce friction to the greatest extent, which can extend the life of the cable. Otherwise, the cable will be worn out after a few strokes.”

The old professor laughed and said: “Mr. Li may not understand the whole story. Acoustic levitation technology is currently immature. The truly mature acoustic levitation technology is to make the car box completely contact the cable. It does not reduce friction. It is. There will still be friction. But once this kind of friction occurs, it will be very fatal and may even break the cable.”

“Immature…”

Li Qi murmured, recalling what he said about friction in his heart, and probably understood some principles.

The old professor lowered his voice and explained: “Furthermore, the acoustic levitation technology is immature, so sonar equipment and a lot of electronic equipment are needed. These equipment want to achieve the effect of “levitation”, the power is very huge. Under the huge power, it needs It is equipment that weighs several tons at every turn. And equipment is just one of them…”

“The second is that huge power must have huge energy consumption. Therefore, batteries that can withstand such energy consumption are needed. These batteries will take up more weight. The total load capacity of the first cable is only five tons, then Mr. Li, do you think it is possible that it cannot even bear this set of equipment? Adding up to a dozen tons of weight, the weight of the equipment is so heavy, it can have a transport effect?”

“Isn’t that as inefficient as the Rockets?”

Li Qi suddenly realized. Only then did I understand why everyone directly opposed the No. 1 filing.

At this time, Xiao Hou had already introduced the filing on the 2nd, and he was very professional and detailed.

Li Qi is not a person in this field. He has no idea about the data in it, but he probably knows the principle of the No. 2 device.

The No. 2 device uses a pulley to operate. From the projector, the shape of the No. 2 design is like an olive. With the integrated molding technology, the cable will be wound and placed in the center of the olive, and the core is hollow. In the part, 24 sets of pulleys constitute the core transmission device. After the No. 2 design is sent into space, this set of pulleys can use the earth’s rotation force to reach the target.

Xiao Hou continued: “The No. 2 scheme is currently 80% feasible in our design institute’s opinion. It has the advantage of stable operation, but…its disadvantage is…because of its small weight, it is thrown out. The speed will be relatively small…”

Everyone fell into silence for a while.

Li Qi carefully looked at the expressions of everyone present, some were meditating, some were disgusted in their eyes. Some are full of approval.

Obviously, this No. 2 plan is recognized in the hearts of many people.

Li Qi whispered again: “Professor, what do you think of this No. 2 plan?”

The professor pondered for a long time and shook his head:

“｀ ¨The second plan is the 24th team hub. It is the easiest way, but it is not simple enough compared to the third that only has two teams with the same’rolling pin’ wheels. Let’s, in fact, the simpler the structure, The less likely it is to go wrong.”

Plan Three…

Li Qi glanced at the drawing above, and was a little surprised at the brains of the design institute.

It looks like a rolling pin.

Use two wheel hubs like rolling pins to sandwich the cable and place the car on both sides. The two rolling pins will roll forward with the cable. This scheme is simple enough.

But after listening to the previous introduction, Li Qi can be regarded as somewhat insightful. He was thinking about a question now…

Even if two rolling pins are the simplest structure, two rolling pins also represent that there are only two bearings.

What kind of bearing can be so wear-resistant?

Can it rotate more than 30,000 kilometers at a high speed in the speed of the second universe without losing it? This question… Li Qi has no solution in his mind.

(Money, Zhao) 　 In fact, among the three solutions, the biggest problem is only one-friction.

The three solutions are all solving the problem of friction.

Acoustic levitation technology can be eliminated.

The second pulley program, and the third rolling pin program. In fact, they are all testing the bearing capacity of the internal ‘bearing’.

The second cosmic speed is to withstand such a high speed per kilometer per second, while at the same time, it rotates at a high speed of its own.

In other words, at this speed, the iron bearing will be burnt red in less than a second, and even burned into molten iron…

So, what material can carry out such abrasion?

Li Qi was lost in thought.

On the summit stage, Xiao Hou Rang was on the side: “I have finished the introduction. Next, I would like to invite experts to express their opinions.”

“I choose plan number two!”

As soon as the voice fell, Su Mingyu shouted immediately. .
