Global Monopoly of Technology

Spring in 2O24.

Luo Sheng's first trip to investigate after the New Year's Day came to the South Peak of Mount Taihua, which is the most dangerous mountain in the world, and this is also the highest peak of Mount Taihua.

Nanfeng has been closed to the outside world for nearly three years, and it has not been opened so far, so tourists who come to Taihua Mountain can only see it from a distance.

The reason is that Star Arrow International has contracted the entire Nanfeng for the purpose of superconducting suspension orbit test of the space ladder. This is the experimental research center.

At about 15 o'clock in the afternoon, a convoy drove into the foot of the South Peak of Taihua Mountain. Luo Sheng got out of his special car, and the assistant of the android girl Zhi Linya also followed him.

"Let's go!"

Luo Sheng and others immediately walked towards the destination. Nanfeng now has a unique wonder. On the steepest peak is erected a towering straight metal steel frame that is perpendicular to the ground. For the parallel special cables, it is the cable used for the ladder, and the interval between the two ropes is about 1.5 meters wide.

The height of the drop has reached an astonishing 2,000 meters, which is basically the same as the height of the South Peak of Taihua Mountain.

There are many low-rise buildings dedicated to experiments built at the foot of Nanfeng, and these buildings are not planned to be dismantled later. With the end of the experiment here, it will be opened as a brand-new tourism project in the future many years later.

"Mr. Luo, it's a pleasure to meet you, welcome to come and inspect!"

Luo Sheng came to the experimental center, and Deng Zigang, the chief technical expert here, came out to receive him with a few people.

Deng Zigang is an expert who has devoted himself to high-temperature superconducting maglev technology for more than 20 years. Twenty-one years ago, he led his team to complete the first manned high-temperature superconducting maglev test line in China. The field of magnetic levitation trains has made great strides.

But he was invited by Star Arrow International ten years ago to tackle a project that made him even more excited. He participated in the high-temperature superconducting maglev project in the space ladder orbit. So far, it has been a ten-year-long attack on this project.

"Old Deng, go straight to the dry goods?" Luo Sheng said with a smile, not at all sloppy.

"Haha, I can't ask for it, please come here." Deng Zigang was stunned for a while and then laughed and said, and immediately brought Luo Sheng and others to a large low-rise building with a simulated vertical track running through the foot of the mountain.

"Old Deng,

Before the room temperature superconducting material is developed, the ladder needs your high temperature superconducting maglev technology, pulleys... I don't think it is reliable. "Entering the empty building, Luo Sheng said with a smile.

"Fortunately, it's not humiliating. The hundreds of billions that Star Arrow International has smashed are not in vain." Deng Zigang was full of confidence, and immediately explained to his team and ordered to show Luo Sheng their results.

Looking around, Luo Sheng saw that when the vertical and parallel cable track extended into the building, it turned into a curved half "U" shape, and the track also extended to the ground, changing from vertical to horizontal.

Looking along the parallel track of the cable, I saw a special vehicle parked on the track, with a streamlined bullet shape on both sides, like a mini version of a high-speed rail locomotive.

"Mr. Luo, the team members are pouring refrigerant into the space shuttle vehicle." Deng Zigang gave a brief introduction, but he didn't say much. He knew that Luo Sheng was different from other leaders. Need to explain too much.

Space shuttle vehicle, this vehicle is an experimental version.

As the name suggests, in the future, the space ladder cable track will rely on this kind of shuttle vehicle to travel back and forth from the ground tower base to the orbiting space station, or to carry people or objects.

The future put into use is much larger than the experimental version.

After a while, after a few staff poured a large amount of liquid nitrogen refrigerant into the shuttle vehicle, a magical scene appeared. The shuttle vehicle suspension, which was originally pressing on the cable track, easily floated up without any other external force. Height is 22mm.

"It is suspended. We can suspend it in the range of 10mm to 30mm according to its needs, but according to our general experience, 22mm is the best." Deng Zigang introduced.

At first glance, it seems to be attached to the orbital cable, but it has actually been suspended, and the shuttle vehicle can be seen to float slightly, but it is always stable within a range.

It is worth mentioning that, from the day superconductors were discovered, the goal of human beings was to find as much as possible a material that works in an environment closer to normal temperature.

Low-temperature superconducting maglev technology generally requires the use of liquid helium to achieve the required temperature, and liquid helium is a precious resource. Low-temperature superconductivity requires such a low temperature, so only liquid helium can be used, which is too expensive to put it bluntly.

Liquid nitrogen is cheaper, and the temperature that can be reached is naturally not as low as that of liquid helium, but the price is cheaper, and high-temperature superconductors do not need the temperature as low as liquid helium, so high-temperature superconductors use liquid nitrogen, which is more affordable than liquid helium. It's less than a thousand pieces of liquid nitrogen.

As for room temperature superconductors, the current technical level has not been done.

Luo Sheng came to the shuttle vehicle, and after looking at it for a moment, he stretched out his hand and pushed hard towards the orbit. The suspended shuttle vehicle was pushed out for a certain distance, and returned to its place miraculously when Luo Sheng regained his strength.

The shuttle vehicle seems to be nailed to the track. This is a unique magnetic flux pinning effect. It shows a restoring force. It is this restoring force that ensures that the shuttle vehicle will not be derailed. It needs to exceed the critical value of the restoring force. The value is derailed, which also means it can hang on the rails.

The stability of being nailed to the track like a nail and the 360-degree suspension give the high-temperature superconducting maglev unique advantages, which are suitable for the space shuttle of the space ladder vehicle.

In fact, people are not unfamiliar with maglev. There are several maglev trains in China that use electricity to make maglev above the track. Of course, it is currently out of service.

However, this high-temperature superconducting maglev vehicle is not suspended by electricity, which is a good news for the space elevator, which can greatly reduce the power consumption of power supply. This is also inseparable from the superconducting materials and liquids developed by Deng Zigang. Nitrogen refrigerant, liquid nitrogen at minus 196 degrees Celsius is the refrigerant for high temperature superconductors.

The high temperature in high-temperature superconductivity is not a high temperature of hundreds or even thousands of degrees, but an unimaginable minus 196 degrees Celsius. The reason why it is called a high temperature is because there is also a low-temperature superconductivity. The refrigerant used is liquid helium, and the temperature It is minus 269 degrees Celsius, far lower than the temperature of liquid nitrogen.

However, adding liquid nitrogen refrigerant is not enough to suspend the vehicle. The high-temperature superconducting material is the key to suspending it. The high-temperature superconducting material developed by Deng Zigang is not a common ceramic material in a low temperature environment. Without any magnetism, superconductivity occurs once in a low temperature environment.

"Professor Deng, take this car to the top of the mountain together?" Lu Ming, who was standing next to the vehicle, immediately invited Deng Zigang, who was stunned for a moment and immediately accepted it with confidence.

Lin Ya, who was accompanying her, hesitated for a while when she heard this. She was an android, but she couldn't disobey Luo Sheng's orders.

I saw Luo Sheng and Professor Deng Zigang entering the shuttle, and several staff members immediately went in to assist them in taking safety precautions, including as if they had checked their seat belts.

If something goes wrong with the two big guys inside, the global economy will have to explode in situ.

"Old Deng, in the post-solar storm era, there are many wastes waiting to be done, which is exactly the historical opportunity to comprehensively update and upgrade urban rail transit. I intend to take the lead in applying your technology to urban rail transit and popularizing it on a large scale, starting from Suzhou City. Start the pilot, and I will go to the city leaders to talk about it later." Luo Sheng tilted his head and smiled at Deng Zigang, who was sitting next to him.

The breakthrough of high-temperature superconducting technology is definitely not only used in space elevators, but also in the transformation and upgrading of urban transportation. There are too many fields that can be used.

"You don't need to ask me about this kind of thing, I'm only in charge of development." Deng Zigang laughed. After a while, his team sent a message that everything was ready. Deng Zigang said in a loud voice, "Xiaohua, take us to the top of the mountain!"

[OK, the shuttle will start in fifteen seconds]

The artificial intelligence on this vehicle responded to Deng Zigang's instructions, and there is no doubt that this is of course the application of artificial intelligence technology under the Cote d'Azur.

Fifteen seconds later, the shuttle vehicle began to accelerate steadily and orderly along the horizontal cable flat track. Luo Sheng, who was sitting in the shuttle, did not feel heavy bumps or waves, and it was very stable. .

As the shuttle vehicle continued to accelerate, the originally horizontal track gradually began to climb the slope, and finally left the low-rise building on the ground. Luo Sheng also saw the exterior.

At this moment, the shuttle vehicle is vertical to the ground, and continues to accelerate and rush along the cable track.

The shuttle is very stable on the track like a nail.

On the way up, Luo Sheng turned his head and asked Deng Zigang, "Old Deng, what is the fastest speed of a maglev vehicle used for ladders?"
