2O24 begins spring.

Luo Sheng's first trip to inspect after the New Year's Day came to the southern peak of Taihua Mountain, which has the most dangerous mountain in the world, which is also the highest peak of Taihua Mountain.

Nanfeng has been closed to the public for nearly three years and has not yet opened. Visitors to Taihua Mountain can only see from afar.

The reason is that Xingjian International contracted the entire Nanfeng, with the purpose of the superconducting suspension orbit test of the space ladder, and this is the experimental research center.

At around 15 p.m. that day, a convoy drove into the foot of the southern peak of Taihua Mountain. Luo Sheng got out of his special car, and the bionic girl Lin Ya who was accompanying him also followed him.

"Let's go!"

Luo Sheng and others immediately walked towards their destination. There is now a unique wonder in the South Peak. A straight metal steel frame towering into the clouds perpendicular to the ground is set up on the steepest peak. The outermost extension is vertically erected by a pair of parallel special cables, which are the cables used for the ladder. The interval between the two ropes is about 1.5 meters wide.

The hanging height reached an astonishing 2,000 meters, which is basically the same as the height of the southern peak of Taihua Mountain.

Many low-short buildings for experiments have been built at the foot of Nanfeng, and these buildings are not planned to be demolished later. With the end of the experiment here, they will open to become a brand new tourism project in the future many years.

"Mr. Luo, I'm glad to meet you, welcome to inspect!"

Luo Sheng came to the experimental center, and Deng Zigang, the chief technical expert here, came out to receive the reception 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. He originally decided to make great progress in the field of high-temperature superconducting maglev trains.

But he was invited by Xingjian International ten years ago to attack a project that even more exciting to him, and to participate in the high-temperature superconducting maglev project of space ladder orbit. At this point, it has been a project that has been going on for ten years.

"Old Deng, just get the real stuff?" Luo Sheng said with a smile, not dragging on the slightest at all.

"Haha, I can't ask for it, please come here." Deng Zigang was stunned for a while and said in a burst of laughter, then he brought Luo Sheng and others to a large low building that simulated vertical tracks through the foot of the mountain.

"Old Deng, before the room temperature superconducting materials were produced, the ladders needed your high-temperature superconducting maglev technology, and the pulleys... I don't think it's reliable no matter how you look at it." Luo Sheng said with a smile when entering the empty building.

"Fortunately, I'm not disgraced. Xing Arrow International has spent hundreds of billions of dollars without any white flowers." Deng Zigang was full of confidence, and immediately explained to his team that he was ready to show Luo Sheng their results.

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

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

"Mr. Luo, the team members are filling refrigerant into the air shuttle vehicle." Deng Zigang briefly introduced that he didn't say much. He knew that Luo Sheng was different from other leaders. He was a high-tech person and did not need to explain too much.

Aerospace shuttle vehicle, this vehicle is an experimental version.

As the name suggests, in the future, the space ladder cable track will be connected to and from the ground tower base to orbital space stations, either carrying people or objects.

In the future, the ones that will be put into use will be much larger than the experimental version.

After a while, after several staff members poured a large amount of liquid nitrogen refrigerant into the shuttle vehicle, a magical scene appeared. The shuttle vehicle, which was originally pressing the cable track, floated easily without the help of other external forces, and the suspension height was 22 mm.

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

At first glance, it looks like it is attached to the track cable, but it has actually been suspended. The shuttle vehicle can be seen slightly floating and swaying, but it is always stable in a range.

It is worth mentioning that from the day when superconductors were discovered, the purpose of humans was to discover as much as possible a material acts in an environment closer to normal temperature.

Low-temperature superconducting magnetolev technology generally requires liquid helium to reach the required temperature, and liquid helium is a precious resource. Low-temperature superconducting requires such a low temperature, so liquid helium can only be used. To put it bluntly, it is too expensive.

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

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

Luo Sheng came to the shuttle vehicle, looked at it for a moment, then reached out and pushed it outwardly towards the track. The floating shuttle vehicle was pushed out for a distance, and returned magically when Luo Sheng retracted his strength.

The shuttle vehicle seems to be nailed to the orbit. This is a unique magnetic flux pinning effect, which shows a recovery force. It is this recovery force that ensures that the shuttle vehicle will not derail and needs to exceed the critical value of the recovery force to derail. This also means that it can be hung on the orbit.

The stability of nailing on tracks like nails and the 360-degree suspension all give high-temperature superconducting maglev unique advantages, which is suitable for the aerospace round trip of space ladder vehicles.

In fact, people have long been familiar with magnetic levitation. There are several maglev trains in China that levitate magnetic levitation above the track through electricity, and of course they are now in a state of suspension.

However, this high-temperature superconducting magnetolev vehicle is not suspended through electricity. This is a blessing for the space ladder, which can greatly reduce power supply energy consumption. This is also inseparable from the superconducting materials and liquid nitrogen refrigerant developed by Deng Zigang. Liquid nitrogen at minus 196 degrees Celsius is the refrigerant for high-temperature superconductors.

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

However, adding liquid nitrogen refrigerant is not enough to allow the carrier to be suspended. High-temperature superconducting materials are the key to suspension. The high-temperature superconducting materials developed by Deng Zigang are not an ordinary ceramic material in a low-temperature environment, which is colorless and odorless, and have no magnetic properties. Once they are in a low-temperature environment, superconducting phenomenon will occur.

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

Lin Ya, who was accompanying him, heard this and stopped for a moment. She was a bionic person, but she could not violate Luo Sheng's instructions.

It was seen that Professor Luo Sheng and Professor Deng Zigang entered the shuttle vehicle, and several staff members immediately went in to assist them in taking safety measures, including checking the seat belt. On the other side, other teams also immediately began to review the situation to ensure that there was no accident.

If something happens to the two big guys inside, the global economy will have to explode on the spot.

"Old Deng, the post-solar storm era is in a mess. It is a historical opportunity to comprehensively update and upgrade urban rail transit. I plan to take the lead in applying this technology in urban rail transit and promote it on a large scale. I will start the pilot program in Sucheng. When I look back, I will talk to the city leaders about this matter." Luo Sheng turned his head and smiled at Deng Zigang sitting next to him.

The breakthrough in high-temperature superconducting technology is definitely not only applied to space ladders, but also has great potential for the transformation and upgrading of urban transportation. There are too many areas where we can use our strengths.

"You don't need to ask me about this kind of thing. I'm only responsible for development." Deng Zigang smiled. After a while, his team sent a message and everything was ready. Deng Zigang immediately said, "Xiaohua, take us to the top of the mountain!"

[Okay, the shuttle will start in fifteen seconds]

The artificial intelligence on this vehicle responded to Deng Zigang's instructions. There is no doubt that this is of course the application of artificial intelligence technology under the Costa del Azure.

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 the heavy bumps, nor did he feel like a wave, and was very stable.

As the shuttle vehicle continued to accelerate, the originally horizontal track gradually began to climb hills, and finally left the low buildings on the ground, Luo Sheng also saw the outdoor scene.

At this moment, the shuttle vehicle has remained perpendicular to the ground and continues to accelerate and rush up along the cable track.

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

While climbing the highway, Luo Sheng turned his head and asked Deng Zigang: "Old Deng, how fast can the maglev vehicle used on ladders reach a maximum speed? "
