Great warships

Chapter 1219 Smart City
After coming to this world, Qin Tao not only promoted the advancement of shipbuilding technology, but also promoted the development of many projects, including nuclear fusion, aerospace, and ground effect vehicles. These things have led the technological progress of the entire world.

When a person has money, he must promote the progress of human science and technology. Otherwise, what is the use of this money? Is it to stare at people's food baskets?
Qin Tao felt very satisfied.

"Boss Qin, the Golden Sun Company is just ahead." Qin Tao was thinking about something in the car after leaving the Fourth Design Office. Xu Zhengyang, who was driving in front, said.

Golden Sun Company? Qin Tao thought of something: "Their company is researching wireless power transmission technology. Let's go in and take a look."

This was at the launch ceremony of the nuclear fusion reactor. Qin Tao heard Max's introduction. Now that he happened to be near the Golden Sun Company, of course he had to go in and take a look.

"it is good."

A large number of high-tech enterprises have emerged in the East, and Golden Sun Company is a typical representative of them. This company started out by manufacturing electric motors and has now developed into a strong player in the field of electric technology.

Advanced technologies such as electromagnetic catapults and electromagnetic arresting cables were all made by Golden Sun Company, which is the best in the world. The integrated power system of warships and all-electric propulsion were also made by them. There have never been any technical defects. Even 100,000-ton aircraft carriers are now beginning to use this technology.

In the civilian field, they were also the first to start developing electric vehicles, and have since been a leader in this field. As early as several years ago, the self-driving Golden Sun electric vehicles had already begun testing, and now, they are even researching wireless charging electric vehicles!

Car manufacturing companies occupy a large area and need various production workshops. Upon learning that Qin Tao was coming to visit, the person in charge, Zhao Peng, immediately came to greet him.

"Mr. Qin, welcome, welcome. Would you like to take a look at the production line?"

Qin Tao nodded: "Okay, let's go to the production line and take a look."

Qin Tao is very familiar with the shipbuilding process, but not so familiar with carbuilding. Since he is here this time, he might as well broaden his horizons.

"The production of a car starts with making the body of the car. The steel sheets need to be uncoiled, cleaned, cut, stamped and then welded into the body."

"In the production of car bodies, do we use a large proportion of aluminum alloy?" Qin Tao asked.

"No, we still mainly use steel bodies." Zhao Peng introduced: "Although aluminum alloy can reduce the weight of the car, it will greatly increase the cost of using the vehicle, especially when repairing it after damage. Many repair shops are not capable of repairing aluminum alloy parts. We only use aluminum alloy on some of the detachable parts, such as the suspension arm, etc."

"So how do we reduce the weight of our car?"

"Of course, we use high-strength steel. Our Mingzhou Group has advanced high-strength steel. The high-strength steel used in important parts of the car can even exceed 2 gigapascals." Zhao Peng said: "With higher strength, less steel will be used, which will naturally reduce weight."

Other car manufacturers do not have steel mills, so they cannot choose the steel they need at will. The steel mills under the Mingzhou Group have advanced technology and smelted steel with high strength, which can also effectively reduce vehicle manufacturing costs.

"In addition to the body, there is also the chassis. The battery of an electric car is best placed on the chassis. This is also the optimal solution after comparing various solutions, but there are still hidden dangers. If the chassis is bumped, it is easy to damage the battery, so we also use high-strength steel plates under the chassis for protection." Zhao Peng continued: "Of course, this is only a transitional solution. When wireless charging technology develops, our electric vehicles can reduce the battery capacity."

When many car companies first started making electric cars, they still used the chassis of fuel vehicles. The power batteries could only be installed wherever there was space, selectively in the front or trunk. In fact, both solutions are not suitable and will cause excessive burdens on the front or rear axle, which is especially dangerous in the event of a car accident.

Almost all newly developed platforms will place the battery on the chassis, so that it is spread out flat and the load is balanced, while the center of gravity is lowered for easy control. There is no problem driving on normal roads, but if the chassis encounters a bump, there may be big problems.

Therefore, this is the best solution after considering all aspects. In fact, it is best not to use batteries.

Without batteries, and it has to be an electric car, then it can be wirelessly charged.

"Yeah, that's right." Qin Tao nodded: "These are just transitions. Hey, it seems that there are very few workers in our factory?"

On the production line, robotic arms are moving back and forth, performing various tasks, from unfolding steel coils to turning them into individual stamping parts and welding them into car bodies, almost all of which are fully automatic.

"Yes, this is the most advanced automated production plant in the world. Except for a few technicians who maintain and service the equipment, most of the processes are automated, which helps improve product quality and reduce production costs," Zhao Peng said. "Of course, some people criticize us, saying that our production line does not provide enough jobs."

Car manufacturing is originally a labor-intensive enterprise, but it has become a high-tech enterprise at Golden Sun Automobile. The modern production line is clean and tidy, and the product quality will not be damaged due to personal reasons. But at the same time, it also means that there are not enough jobs available.

"Yes, there is indeed a problem, but it is also inevitable with the development of the times." Qin Tao said: "Just like during the British Industrial Revolution, when craftsmen entered factories and smashed machines, it was useless to stop them. We must always remember that if we fall behind, we will be beaten."

The extensive use of robotic arms and automated production is an inevitable result of historical development. Mingzhou Group has been at the forefront of the world and is even the most advanced.

In shipbuilding, there are so many orders that if we rely solely on workers, we will never be able to handle them. It is precisely because of the large number of advanced machines that we can deliver ships quickly and well, reduce costs and increase profits.

The same is true when it comes to car manufacturing.

"At present, the production cost of our Golden Sun electric vehicles has been made the same as that of fuel vehicles. Even without the government's policy subsidies, they are still very competitive in the market. Of course, according to your arrangement, our current selling price is still maintained at a high level, which also allows our company to obtain a lot of funds. The various technologies developed for the military are almost all drawn from the profits of electric vehicles."

The cost is already the same as that of fuel vehicles, and they can be rolled out at any time to compete with fuel vehicles. However, electric vehicles are still high-end products, so the pricing is not low and the profits are huge. These profits can be invested in the research and development of military products. Otherwise, they would be embarrassed to always take money from the group.

"The wireless charging technology we are researching now also requires a large amount of investment." Zhao Peng continued, "After the research and development is successful in the laboratory, we still need to renovate a section of the road..."

At this time, Qin Tao had already seen the car shell being welded in the hands of the robotic arm. The appearance looked very beautiful. When he heard Zhao Peng talk about this, he suddenly became interested: "It would be too easy to just renovate the road. If we want to do it, let's do something big."

"What's so big?" Zhao Peng also felt his breathing quicken.

“Do you know about smart cities?”

Zhao Peng shook his head: "Literally speaking, the city has a brain and is more intelligent?"

"Yes, that's what I mean." Qin Tao nodded: "A city has a brain, and this brain is a supercomputer. Or, in other words, there is no supercomputer, but a group of computers connected through the Internet."

If we talk about big data and the Internet of Things now, I guess many people don’t understand what you are saying. However, it is time to make these preparations now.

The Internet was invented by Americans, so they have always had an absolute advantage. Fortunately, computer technology has developed rapidly, and the Minnesota Group has come from behind to surpass the West, but it is still weaker than the West on the Internet. For example, the number of IP addresses in a single American university is more than the total number in the East.

Fortunately, Dongfang has its root server, and with the advent of the IPV6 era, Dongfang can be considered a latecomer in this regard, and will then lead the entire era.

How to lead? Of course, relying on advanced technology!
More advanced than the Internet is the Internet of Things. All objects can be connected to the Internet in various ways, exchange various data, and achieve intelligence.

Many people can understand the concept of big data. It analyzes your habits. If you use it frequently, the price will be high. If you use it for the first time, the price will be low. The low price will attract you, and then you will cultivate the habit of using it. After you have familiarized them, you can price them low.

"what is the benefit?"

"For example, if a thief steals something, he will be located immediately, and then the nearby cameras along the way can be mobilized for supervision. Even when the thief is escaping, the traffic lights can change in time to intercept the thief on the spot."

"Thief?"

"Okay, let's change it. For example, if someone faints on the street and is discovered by the health monitoring device they are wearing, they will directly call 120. 120 will receive all the information on the scene and can even formulate a medical plan in advance through the device worn by the person. The traffic lights along the way will turn green to meet the needs of the ambulance to arrive in time..."

Zhao Peng opened his eyes wide: "Is it possible? All of this doesn't require human control?"

"Yes, since it is a smart city, of course it is not controlled by humans. People just need to input commands."

"That's really a future to look forward to!" Zhao Peng sighed.

“Yes, we may be able to see such a future.”

At this time, Qin Tao continued to walk forward along the production line and saw the car body assembly line. Various robots were busy, assembling various parts onto the car body in an orderly manner. There were also some workers monitoring the operation of the robots.

"Just like 20 years ago, could we have imagined that so many jobs would be replaced by robotic arms?"

Even spraying anti-rust coating on the chassis is done by robots. This kind of work is not only tiring, but also harmful to the health of workers. After all, it must be unpleasant to smell the smell of paint all day long.

But now, these positions can all be operated by tireless robots!
"Mr. Qin, when did you come? Why didn't you notify us in advance?" At this moment, several people came hurriedly, led by Mr. Ma.

"I was just passing by and came in to take a look."

"Well, Mr. Qin, I'll accompany you."

Zhao Peng is in charge of the production of electric cars here, but he is not the top leader of Golden Sun Company. The person in charge here is Engineer Ma. However, Engineer Ma is mainly engaged in research and development and rarely comes to the production line. He heard that President Qin was coming today, so he hurried over.

Qin Tao nodded: "I looked at the production line, but it was just a cursory glance and I couldn't see the whole thing. I'd better go to your laboratory to see your electric vehicle wireless charging technology and discuss the future."

"it is good."

Zhao Peng was speechless and said, "Mr. Qin, if you can't understand these, you will definitely not understand Mr. Ma's techniques."

"When Maxwell was studying the electromagnetic induction phenomenon, he used two coils. When one coil was connected to the power supply, sparks would be generated at the end of the other coil. This is actually a wireless charging technology." When we went to the laboratory, Ma introduced: "This electromagnetic induction wireless charging method has a simple principle and is easy to make, but the charging power of this charging method is small and the transmission distance is short."

"In addition to this method, there is also..." When Ma Gong said this, he suddenly thought of something: "Boss Qin, can you choose a suitable technical route for us?"

"How should I know?"

"Mr. Qin, you pointed out the medium-voltage DC integrated power technology to us. Facts have proved that this route is completely correct. The electromagnetic catapult, electromagnetic gun and other technical routes you pointed out to us are all correct. In the field of electric vehicles, we also want you to point out a qualified technical route."

Qin Tao was somewhat helpless. I could point out those things that were correct because I already knew them, because I was a reborn person. But now, you want me to point out a clear path, but I don’t know it myself!

"Boss Qin, Boss Qin?"

"Which route do we think is the most suitable at the moment?"

"We are currently researching magnetic resonance technology, which can also be called resonant induction or resonant coupling technology. The two coils of the transmitting and receiving devices are used as resonators to transmit energy through the resonance effect. Compared with the former, it has a longer transmission distance, higher power supply efficiency, and supports one-to-many power supply methods."

"Well, are there any technical difficulties in this method?" Qin Tao nodded.

"Yes, for example, if you want to perform energy legend, the two devices must be adjusted to the same frequency, which is difficult to adjust."

“Can we conquer it?”

“It is currently being studied.”

"In that case, let's follow this route. I believe that our scientific researchers can solve these problems." Qin Tao said, "When that happens, our electric cars will be able to charge while driving. By the way, I have an idea for a smart city..."

Qin Tao really doesn't understand these technologies, but since Ma and his colleagues are researching this technology, it means that this technology should be the most suitable option among all these technologies.

As for the research being wrong? It doesn’t matter. We can still be number one in another field. We have rich technical reserves.

At this time, everyone had entered the laboratory. Looking at the busy figures of countless people inside, Qin Tao knew that it was meaningless to continue listening to Engineer Ma explaining these technologies, and it would only embarrass him. He might as well just say what he imagined.

"After we achieved initial results in the experiment, we needed to build a wireless charging road. However, with only a simple road, we could not simulate the real situation. So I decided to build a city. It doesn't have to be too big, just a town with a population of 100,000. When the whole city is being built, we will lay out our wireless charging devices."

"Mr. Qin, you are really generous." Mr. Ma exclaimed.

In order to support the research and development of electric vehicles, President Qin actually wants to build a city!
How much does this cost? Only the Mingzhou Group is so wealthy that it dares to do this!
Mingzhou Group's construction company has developed rapidly and is now the construction company with the best reputation and the greatest influence in the country. In particular, its method of handing over the keys and obtaining a certificate upon purchase of a house has been deeply popular among the public.

This requires a massive capital investment. Without strong financial resources, it is impossible to advance so much money. Other developers are complaining bitterly, but there is nothing they can do but follow the Mingzhou Group, because if the houses are not built, no one will buy them even if they are sold!

Other companies cannot afford such a big investment, but Mingzhou Group can. As long as they negotiate with a city, they can obtain the land and build a new city directly!
"If you really want to do this, I suggest choosing a city in the north."

"why?"

"Because our current electric vehicles are not suitable for northern cities, with this new technology, they can be better adapted to northern cities!"

The energy of electric vehicles comes from batteries. The battery uses chemical methods to transport charges and form electric current. The chemical reaction is closely related to temperature. The north is freezing cold. Electric vehicles have a range of 500 kilometers in the south, but only 200 kilometers in the north, and the heater cannot be turned on.

Therefore, Golden Sun electric cars are mainly sold in the south and rarely enter the north. Even if customers want to buy them, they have to explain these defects in advance.

With wireless charging, there will be no problem of shortened driving range. How can the battery run out? As long as you are on the road, you can charge wirelessly at any time!
"Okay, then let's go to the north to coordinate a city." Qin Tao nodded and left the matter to his subordinates.

Suddenly, he thought of something else: "Does our wireless charging technology have a lot of radiation?"

Generally speaking, electromagnetic radiation is harmless. After all, sunlight and fire are also radiation, which are normal. What is threatening is ionizing radiation, such as the radioactivity in nuclear reactors. Fundamentally speaking, electromagnetic radiation is produced by the energy level transition of the outer electrons of atoms, and ionizing radiation is produced by the decay of the nucleus.

However, excessive electromagnetic radiation can also cause unnecessary trouble. Some people are very difficult to please. On the one hand, they don't allow base stations to be built on their rooftops, but on the other hand, they demand full signal for their mobile phones.

"Of course there is radiation, but it is limited to the roads. It can be isolated by setting up a two-meter green belt between the motor vehicle lane and the non-motor vehicle lane. As for motor vehicles, the body of the vehicle can become a Faraday cage, which has an electrostatic shielding effect, so there will be no problem. In fact, the radiation dose will not be very large. Even taxi drivers who are on the road all day will not be affected much."

"That is to say, it is still necessary for us to build a city as a sample first."
