On August 25th, the weather was fine.

Zhou Yu has been accompanying Chen Jin these days and spending this period of his weakest body with her.

"Husband, I've been recovering well these days, don't always accompany me, the company still has so much work, and now I'm recovering well, you should also focus on work."

When Chen Jin was changing the child's diapers, she said to Zhou Yu, who was sitting on the side.

During the period of confinement, even if there are intelligent robots that can help her deal with things, Zhou Yu has always been by her side, accompanying her to take care of the child, and preventing her from suffering from postpartum depression because of a bad mood.

Chen Jin feels that her psychology is very healthy, and she herself is very happy. It is impossible to suffer from mental illness.

Zhou Yu saw that Chen Jin's complexion was very good, he nodded and said, "Well, through the virtual world company, some things are really inconvenient.

Xiao Jin, you are also in a good state now, then I will go out to work during the day and accompany you to take care of the children at night. ”

Zhou Yu said goodbye to his two children, and he left his home and walked towards the scientific research center.

The company's artificial intelligence has been upgraded, even if he is not in the company, Xianghua can cooperate with executives to deal with anything in the company.

These days, he handles the company's administrative business through virtual world network meetings, and now that electronic contracts are officially available, the company is very easy to manage.

Zhou Yu's guidance of the scientific research center project can solve most of the problems through the virtual world network conference, but some core complex problems or problems that are inconvenient to discuss in the virtual world still need to be dealt with by him personally.

Zhou Yu was the first to come to the mechanical laboratory, and Liu Jing began to develop maglev vehicles at an early age.

They finally decided on two maglev vehicle schemes, and asked Zhou Yu to decide which scheme to adopt, so that they could continue to develop ancillary facilities.

These two options are not compatible, and one must be chosen.

When Zhou Yu came to the mechanical laboratory, Liu Jing, the director of the mechanical laboratory, immediately greeted him.

"Mr. Zhou, you have time to come, you are resting at home during this time, and I don't want to disturb your life."

"If there's something, we'll talk as we go." Zhou Yu said in a slightly apologetic tone.

"Mr. Zhou, because most of our company's products are very time-sensitive, air transportation is inconvenient, and high-speed rail transportation does not have enough volume.

It just so happens that breakthroughs have been made in superconducting materials, and breakthroughs have also been made in energy storage materials, especially in the magnetic levitation technology developed by me.

I applied for the development of a maglev vehicle project, and now the project has entered a fork in the road, and I must choose one of the two paths as the main development direction. ”

Zhou Yu and Liu Jing came to the office, and he saw a rough model of the maglev vehicle.

Its shell forms a closed pipeline, and the maglev compartment is suspended in the center of the pipeline.

"This is very similar to the hyperloop that Elon Musk used to promote, of course, this is just a money-making project, and even a kilometer of hyperloop has not been officially operated until now.

What are the two development paths you are talking about? Zhou Yu asked.

"This is the vacuum maglev pipeline we have developed for magnetic levitation vehicles.

Our first development path is similar to that of the hyperloop, which is the transportation of people and goods, mainly to transport people.

The air resistance is reduced by a vacuum duct, and the super-strong magnetic field formed by the superconducting material pushes the cylindrical carriage in the center forward rapidly.

The cylindrical shell is arranged with superconducting materials, and the super magnetic field from the outside cannot invade the inside of the car and will not affect the people and items inside.

The carriage in the vacuum maglev pipeline can reach 20,000 kilometers per hour, and it is only a few minutes from Yanjing to Shanghai, and you can travel all over China in less than an hour.

This choice adopts the option of mixing people and goods, which is conducive to the development of vacuum magnetic levitation track in the future.

It requires the development of extremely complex safety systems with very high requirements for magnetic field strength and acceleration clearance.

The second method is that it is only used for freight, so that the entire pipeline is not too complicated, but there is no development potential, and no matter how it is upgraded, it cannot take people and living creatures.

Because there is no security, living beings simply cannot withstand strong acceleration. ”

Liu Jing introduced two directions for the development of vacuum maglev pipelines.

"Your vacuum maglev pipeline is very similar to the hyperloop, but Elon Musk's hyperloop is a complete gimmick, he himself has not invested in this project, but we have the strength to build a vacuum maglev pipeline.

At 20,000 kilometers per hour, such a high speed, it has far exceeded the speed of airplanes, and has reached 15 times the speed of sound.

What method do you use to allow ordinary people to ride a vehicle that starts acceleration so quickly?

Experienced astronauts, if they want to reach this level, need long-term training and a comprehensive set of equipment.

There are not many people in the whole of Huaxia who can withstand this kind of acceleration. Zhou Yu asked with some doubts.

Running at speeds of more than 15 times the speed of sound, even with a relatively gentle and uniform acceleration, the resulting acceleration is powerful enough to cause a serious strain on the heart and brain.

Once this kind of high-speed train is operated, it will have very serious consequences, and it must not be only a few people who can ride it.

Transportation that ordinary people can't take, that's just a joke.

Liu Jing said briefly: "The biggest difficulty in choosing the way of mixing people and goods is to ensure the safety of personnel, and our technology is not very mature.

It is necessary to cooperate with relevant laboratories to jointly develop life-sustaining devices.

For the time being, the solution is to give the passengers a drug to minimize the activity of their brains and organs and put them into a semi-dormant state.

In this state, their perception of the outside world is not obvious, as if they have become an object, which can increase their resistance to drastic changes in the outside world. ”

Zhou Yu waved his hand and directly denied: "This plan can't work, unless everyone is superhuman in the future, otherwise the risk it contains is too great."

Riding in the car also requires medication, not to mention the potential risks brought by drugs, passengers are psychologically unacceptable.

It's not two options, it's only one. You mainly study vacuum maglev pipes for transporting goods.

Now that science and technology are developing with each passing day, perhaps when the vacuum maglev pipeline can not adapt to the future transportation requirements, we have already considered convenient air transportation. ”

After listening to Zhou Yu's analysis, Liu Jing smiled and said: "Then according to Mr. Zhou's analysis, we will develop a vacuum maglev pipeline for special freight."

This project was officially determined as the super freight high-speed rail, and we began to develop the supporting equipment of the super freight high-speed rail. ”

This scheme is also in line with Liu Jing's own choice, and this high-speed transportation method is naturally suitable for freight.

Personnel transportation can be carried out using the high-speed rail network, and the high-speed rail transportation will reach 500,800 kilometers per hour in the future, which is already the maximum speed that people can adapt to when they take transportation to ensure comfort.

The vacuum maglev pipeline has a very large investment, only using the freight mode, and its upgrade potential is almost none, and it can only be used as a logistics channel in the future.

With this kind of huge project, Liu Jing didn't dare to make a decision at will, he could only wait for Zhou Yu to finally make a choice.
