Chapter 552: The City of Stars

The real estate project of Xingchen Technology in Yangpu District was officially announced. The exhibition center was full of guests. Luo Jia made a simple warm-up scene. After successfully arousing everyone's appetite, she pushed open the door of the next hall under the gaze of attention and presented the entire project to everyone.

I saw that in the lobby next door, there were 3D printed project models. Although they were just models, they still brought great shock to everyone. Towers were like Optimus Prime and built on several air bus stops at different heights, indicating that they have an integrated super transportation system of ground-space.

In addition, the building materials also surprised the experts present. It seemed that the building did not bear the reinforced concrete, but used a nearly transparent composite building material, which was piled directly on the foundation like building blocks.

Of course, what shocks people the greatest shock is the height of the building.

The city of Hudu has always been known for its high-rise buildings. However, the three major building complexes of Xingchen Technology are like a city in the sky, high above, overlooking the entire capital of Hudu, including Lujiazui, which has the most super buildings.

"What the hell is this!"

"Not to mention Universal and Jinmao, this height is at least twice that of Dubai Tower!"

"Such a huge single building should be able to accommodate many residents."

"Crazy, Xingchen Technology is completely crazy!"

"I think it's good. The extreme use of height to increase the floor area ratio, the surrounding green space has increased significantly, and there are even woods and streams."

"If this kind of super community can be built, I would be willing to move in."

"You must be able to afford it or pay the rent. Although it is in Yangpu District, super skyscrapers like this will definitely not be cheap."

People were talking about it, all of whom were shocked by the spectacularity of the three major building complexes. The advanced design and the extremely crazy architectural height made them feel that they stood out. Compared with the surrounding buildings, these three major building complexes seemed to come from science fiction movies, and their designs and materials were all far beyond their contemporaries.

"This is our answer." Luo Jia said in a deep voice: "Since the city of city is limited, we should make up for it with the height of the building. The design we see now is called the City of Stars. Each City of Stars is composed of twelve super-high-rise residential buildings, with a single height of 1,858 meters, a total of 420 floors, accommodating 80,000 residents and 160 elevators."

"The total population of the city of Stars is close to one million. In addition to residential areas, in the area close to the ground, it also has huge commercial areas, restaurants, supermarkets, schools, kindergartens, gyms, and hospitals."

"In short, all living facilities that everyone can imagine can be found in the City of Stars, providing all-round and all-weather services for those living here..."

Luo Jia talked freely. Simply put, the City of Stars is a work that makes great miracles. In the city, land is scarce. As a latecomer in the industry, Stars Technology does not have enough development land. In this case, rational use of resources and building floors as high as possible will become their only choice.

In fact, in human history, or in those visionary science fiction novels, there is no shortage of concepts similar to supercities. As the population increases, cities will definitely become larger and more crowded. High-rise buildings are almost the only choice to increase urban floor area ratio in the future.

"I know that when facing the City of Stars, you must have many questions to understand." After Luo Jia briefly introduced, he glanced at the audience and said to everyone with a smile: "Any questions, any speculations and doubts related to the City of Stars, can be asked. If you are ready, let's start now. Students who want to ask questions, please raise your right hand."

As soon as Luo Jia finished speaking, with a swish, countless arms raised on the spot. There were so many people who wanted to ask questions. Without an outline, allowing the media to ask questions freely is undoubtedly a test for Luo Jia, because no one knows what tricky questions people would ask.

"I would like to ask, is the building height really 1,836 meters? How do you decide the building height? Are you not worried about the thin oxygen and low temperature of high-rise residential buildings?" After being named by Luo Jia, a young man with glasses stood up and asked.

"You are not a problem, but several problems." Luo Jia said with a smile: "The altitude of Kunming is 1,891 meters. I have never heard the people of Kunming complain about lack of oxygen. The altitude line for altitude sickness is 2,500 meters, so even living on the top floor of the Star City is safe."

"As for the height of the building, believe me, that is the most irrelevant issue. Since the Jeddah Kingdom Tower, which is a big dog, can be built to 1,07 meters, and the Burj Khalifa in Dubai can be built to 828 meters, why can't we in China build higher?"

"At that time, I asked my colleagues how high the Star City is, some said 1,200 meters, and some said 1,500 meters. However, in the end we accidentally designed 1,836 meters."

"What does one thousand eight hundred and thirty-six meters mean?"

"There is nothing special. The world's tallest building, Jeddah Kingdom Tower, plus the world's second tallest building, Dubai Tower, totaling 1,835 meters. Our Star City is 1,836 meters, which means one meter taller than them in total."

Pooh ~

As soon as Luo Jia finished speaking, the scene was already filled with laughter.

"Awesome! One meter taller than the world's first and second in the world combined? Star Technology is awesome!"

"I did a pretty job! I like to watch the scene where the tough guy team has a strong battle against others. It's 1,836 meters. The big dogs are stunned this time!"

"A accidentally designed 1,836 meters? My God, how careless are these straight men in Xingchen Technology?"

"Let's see who the sky has spared. The big dogs would never have thought that they are today!"

The crowd was talking, and a strong sense of pride arose.

Most Chinese people have no good feelings for the big dogs. As a typical example of getting something for nothing, they discriminate against women. Thousands of princes have various corrupt practices. They are completely the slave-making style of ancient clans and tribes, and they do not belong to a modern country at all.

The crude oil business has been severely suppressed by Xingchen Technology. In recent years, the big dogs have lived a hard life. If this continues, they will have to go back to the desert to release camels. So, after all, the whole family will just use their savings to engage in tourism and sell real estate.

But there is a lot of tourism resources in a barren land like the desert. The only way is to create it yourself and give full play to the talent of the big dogs who are very fond of merit. They can come from luxury and attract attention.

People may not know that Dubai, the famous desert pearl, has actually lost crude oil production for a long time. Its economic pillars are tourism and real estate, plus part of re-export trade. The Dubai Tower, six-star sailing hotel, and magnificent shopping centers we know are actually gimmicks made by Dubai to attract tourists. Otherwise, no one would have gone to the desert to travel. If the desert is suitable for the development of tourism, the Sahara Desert would have been lifted out of poverty long ago.

The City of Stars emerged, and the blow to the big dogs who are transforming into tourism and real estate is too great. You must know that each City of Stars consists of twelve huge buildings of 1,836 meters. In the Yangpu district alone, Stars Technology will build three City of Stars. Those Jeddah Kingdom Towers, Dubai Towers, and Stars City are not enough to see.

"You are so brave, 1,836 meters? Millions of residents? Such a super building has not been scientifically proven? If there is any accident, can you Xingchen Technology take responsibility!?"

At this time, a stern question came from the crowd. Luo Jia frowned slightly and looked over the voice. He saw that it was a group of real estate bigwigs surrounding Boss Yang. They looked as if they were ashen, with their arms around him.

If the Star City project can be really completed, the current real estate companies will inevitably face huge difficulties. On three small pieces of land in Yangpu District, which is not too large, it will resettle three million residents. Such a terrifying floor area ratio will greatly dilute the land price.

As we all know, the largest part of the housing prices in Shanghai is land, which can be said to be valuable in every inch of land. The high floor construction is the lowest, and the land price is shared. Although the Star City seems to have traveled through the future and looks extremely shocking, it is hard to say which cost less than ordinary real estate in the same area. If the cost of Star City is 30% lower than that of other real estate developers, it will establish a crushing commercial advantage.

Faced with the doubts of real estate developers, Luo Jia smiled, "Only talking about building height and not building materials, it is just a hooligan. The so-called safety depends on the technology level. Low technology level, no matter how low the building height is, it is dangerous. High technology level, the building height is safe to penetrate the sky!"

"If you don't believe it, you can check out our No. 1 elevator, which has a height of 36,000 kilometers, and it goes directly from the surface to the synchronous track!"

After a pause, Luo Jia said to the real estate tycoons at a fast speed: "If you have learned material mechanics, you will know that if the building cross-sectional area is A, the compressive strength is σ, and the heaviness is γ. When the height reaches h, the volume of all the trunks is multiplied by the height, and the weight of all the building is volume multiplied by the weight."

"Since the bottom of the building has to bear all gravity, we multiply the compressive strength by the area, and we get the expression of the limit state, h=σ/γ."

"Take the common reinforced concrete as an example. The nominal strength of C30 concrete is 30 megapas, and the weight is about 25 kiloN per cubic meter. Then its theoretical limit height is 1,200 meters. Once it exceeds this height, the building will be crushed by its own weight."

"The strength of titanium alloy is about 900 megapas and a weight of 44 kN per cubic meter. Suppose we use titanium alloy to make buildings, the theoretical limit height is 20,454.545 meters."

"It should be noted that the strength of titanium alloy is three times that of steel, and the weight is only half of the steel. Therefore, the ultimate construction height of titanium alloy is six times that of steel, which is what we call lightweight and high-strength structural performance."

"Lightweight and high strength is one of the most important theories in material mechanics and architecture. Our graphene and carbon fiber are typical lightweight, high strength and perfect materials. Now you should understand it? One thousand and eight hundred meters are just pediatrics for us."

Too bullying!

All the real estate bosses were stunned and looked extremely ugly. Luo Jia was a technical boss, and these real estate bosses knew nothing about material mechanics.

"Is there any other question?" Luo Jia looked around with a smile.

The City of Stars is the result of the powerful miracle of straight men from science and engineering. As for why he is persistent in transforming big cities, it is mainly to cooperate with the actions of the national team.

In December 2019, the country officially established a development plan with big cities as the core, tilting resources towards big cities and regional central cities. Assuming that you live in core cities at this moment, you are lucky because in the next few decades, you will enjoy more economic development results. If you live in small and medium-sized cities and rural areas now, you may be considering moving to central cities. After all, people should pay attention to following the trend in their lives.
