Black technology: a super empire spanning two worlds

Chapter 151 [Why build a subway? Let’s build a superconducting skytrain]

After ending the call with Xu Changming, Xiao Yu looked around. He was now in the 9th villa in the villa area.

The previous owners of this villa have all moved out, and the other 35 villas in the entire villa area have been bought by Xiao Yu, and all the owners have moved out.

After a while, Xiao Yu came to the basement alone. He looked around and nodded with satisfaction: "This owner is great. He built such a large basement."

He chose Villa No. 9 not only because of its good location, but also because the owner of this villa had made a major renovation to the basement, leaving a very large space.

Finally, Xiao Yu opened the teleportation star gate, and then adjusted the star gate to the maximum range that the underground warehouse space could accommodate.

I saw a fully automated engineering equipment from the Blue Star world passing through the star gate, entering the underground warehouse, and then starting excavation operations. This equipment was not large, because the current operating space was small and it was not suitable for larger equipment.

When the space for digging downwards is larger, Xiao Yu will open a teleportation star gate in the newly vacated space, allowing larger equipment to continue digging underground. At that time, the efficiency will increase exponentially.

After more than half an hour of hard work, everything was arranged properly and radio signal jammers had been placed around the villa.

It cannot be detected from the outside, and the signals are not communicated during excavation and construction operations.

Because the teleportation star gate needs to remain open all the time, when the star gate opens to connect the two worlds, the time flow rate difference between the two worlds will be equal, and there will not be a 500-fold difference during the period.

In the long run, some radio wave signals from the Blue Star World will be transmitted to the Earth through the star gate, and vice versa, the radio wave signals from the Earth can also be transmitted to the Blue Star World.

Obviously, Xiao Yu does not want the humans in the two worlds to know each other's existence, so he has to block the signals, and prevent the radio signals from the Earth from being transmitted, and the radio signals from the Blue Planet from being transmitted.

After finishing the task, Xiao Yu left the villa, while the excavation work in the underground garage was being carried out in an orderly manner.

According to computer simulation results, this underground laboratory base can be built and put into use in about half a year, but it is impossible to complete the entire construction according to Xiao Yu's design within half a year.

This does not affect the use of the modules that have been built. The entire underground laboratory base is built in partitioned modular structures, and if there is a need in the future, it can continue to be dug deeper and expanded.

This villa is already filled with surveillance equipment, which will immediately alert Xiao Yu if someone approaches. He can close the teleportation gate remotely at any time by controlling the teleportation ring on his wrist, so he doesn't have to keep an eye on it.

Moreover, the entire villa area has been cleared in advance, there are no outsiders, and the probability of being broken into is basically zero.

……

About twenty minutes after Xiao Yu left the villa, he received a call from the city leader, inviting him to attend a seminar in the city to study the future development of Linzhou City.

Xiao Yu is now the richest man, and Lingjing Technology, the largest taxpayer in Linzhou City, is located here. Another promising company, AVIC Linfei, is also here. These are all companies founded by Xiao Yu, so it would be impossible not to invite him to attend the meeting.

At this moment, several city leaders and people from the Municipal Planning Bureau were discussing Linzhou City's plan to build a subway at the meeting. Xiao Yu was also present.

There is no subway system in Linzhou City now, and the reason is very simple: there is no money.

Before the rise of Lingjing Technology, Linzhou City was just an ordinary second-tier city that was not ranked high, let alone compared with first-tier cities. It had never even thought about a huge infrastructure project like a subway system.

But now it is different. With the rise of Lingjing Technology, fiscal revenue has doubled. With more money in their pockets, they want to build a subway. At this time, the city's top leader looked at Xiao Yu and said, "Comrade Xiao Yu, if you have any opinions or suggestions on Linzhou's entire development plan, please share them with us."

Xiao Yu had already read the overall planning proposal, and after thinking for a while, he said, "I personally think the other plans are quite good, but let's not build the subway. My reason is very simple. The superconducting era is about to come in the foreseeable future, and the subway will become a useless transportation facility in the superconducting era."

After a pause, Xiao Yu looked around at the leaders present and continued, "The cost-effectiveness is extremely low, and the operating cost is very high. Since we don't have a subway in Linzhou, there is no need to build one. The superconducting era is the general trend of the future. I personally think that we should vigorously develop the low-altitude economy."

It is suggested not to carry out the subway project. There is an important reason for this. Xiao Yu does not want the city to plan the subway route to extend to his villa area, so as to avoid exposing the secret laboratory base he has built underground during drilling.

But Xiao Yu was right not to recommend building a subway. Under the future expectations of the superconducting era, future transportation systems should no longer extend underground, but into the air.

Xiao Yu thought for a moment and added: "With the advent of room-temperature superconducting materials, low-altitude economy will inevitably become the general trend of the future. Why doesn't Linzhou City prepare in advance for the layout of a three-dimensional transportation network? It will not be long before superconducting floating flying cars will be born and popularized. The low-altitude economy is promising."

The city attaches great importance to Xiao Yu's suggestions and opinions, otherwise they would not have specially invited him to attend the meeting.

After all, Xiao Yu is currently at the peak of his career and is highly valued by the higher-ups. With Xiao Yu's full support, the achievements in economic development will not be too bad. Naturally, the top leader of Linzhou City attaches great importance to him.

A leader who attended the meeting said: "I agree that the arrival of the superconducting era is a major trend, but it may be difficult to achieve in the short term. Comrade Xiao Yu, you also said that room-temperature superconducting materials are still some way from mass production. It cannot be achieved in the short term, and the current cost is very high."

Hearing this, Xiao Yu smiled and said, "It's not a big problem. We can do it on a trial basis first. The military probably won't be able to use up all the room temperature superconducting materials. The main reason is that they are too expensive. It's impossible for all military expenditures to be spent on them."

"Private cars will definitely not become popular in the short term, but public transportation projects can be developed. I can use the HP Foundation to fund some non-profit public transportation projects. If we want to develop them, we should make them more sci-fi and make Linzhou unique in the contemporary era."

The city's top leader immediately asked, "Oh? What do you mean?"

Xiao Yu said straightforwardly: "Why build a subway? If we want to build one, we can just move the subway from underground to the air and build an aerial railway. The subway cannot be expanded after it is built, so the aerial railway can just increase its height. It is not only convenient but also low-cost."

Skytrain?

The leaders present at the meeting were all stunned.

Xiao Yu continued, "If we only rely on the Earth's magnetic field to float the train, we need a lot of room-temperature superconducting materials to support it. The superconducting materials we have synthesized can carry objects about four times their own mass by relying on the Earth's magnetic field alone. In other words, if a 4-gram mixed object is to float, room-temperature superconducting materials must account for about 100% to float it."

"With such a proportion, the current cost of room temperature superconducting materials is 1 million per ton. The cost is definitely unbearable." At this point, Xiao Yu changed the subject: "But it is not unsolvable. There is still a compromise to reduce the proportion of superconducting materials."

One of the leaders at the meeting couldn't help but ask: "What plan?"

Xiao Yu said in a deep voice: "Then we can lay magnetic tracks, for example, under the green belt in the middle of the highway. The artificially enhanced magnetic field is much higher than the earth's magnetic field, so that the train can run on a fixed route at a height above the green belt where the magnetic track is located. In this way, we can reduce the proportion of room temperature superconducting materials in the carriage, and the cost will be reduced."

As a public transportation project, the floating train is different from the floating car that needs to run everywhere. The train only needs to run on a fixed route, just like laying rails now. The difference is that the floating train lays magnetic tracks, and the magnetic field can be artificially strengthened within the range of the magnetic tracks.

Less room-temperature superconducting material is used, but as long as the magnetic field strength is increased, a balance can still be achieved, allowing the carriage to float above the magnetic track. Relatively speaking, the cost of laying the magnetic track is much lower.
