As he said to Nie Shuying, Xu Yuan planned to build a city.

Not on land, but at sea!

With the development of the Qatari economy, a large number of foreign workers and tourists poured into the country, and the Lucas Islands, which were not large, were instantly crowded.

And the originally loose residential land has also begun to be strained.

Although it will not make these indigenous people who have enjoyed the dividends of economic development unable to buy houses, it will undoubtedly increase their cost of living and raise the threshold for immigration.

Even if Qatar has the economic conditions for population growth, but the area is not a large island, how many people can be cram into it?

The country is vast, but not on land, but at sea.

Backed by the vast Pacific Ocean and the open sea, such a unique geographical advantage, if not used, it is really too tyrannical.

The next strategic focus of Yuanying International Group and Wishing Star Trading Company is to expand into the ocean!

And this will serve as a prelude to the space age.

In the afternoon, Xu Yuan came to the vicinity of the Source Shadow International Building, located in the northeast corner.

This area, due to pre-planning, has gradually formed a high-tech park that represents the most cutting-edge technology in Qatar.

It's also the most heavily guarded, with doorways and walls guarded by soldiers wearing mechanical exoskeletons and patrolling by drones.

Access control does not use ID cards, only authentication through iris recognition.

The level of security here is second only to Xu Yuan's private villa, and even slightly higher than the presidential palace in the city center.

But even so, walking in this science and technology park will not make you feel the slightest bit of oppression in a military powerhouse.

With the exception of patrols outside the walls, drones usually lurk in the hive and are on standby, only swarming towards the source of the alarm when the alarm is triggered.

The obedient consciously lie down, the disobedient lie down with rubber bullets, and as for the one with the weapon, then it is embarrassing.

In this science and technology park, there is no so-called military center or forbidden area, and there are some special places where you can't enter if you don't have enough permission.

For example, the Nanomaterials Laboratory located in the building is mainly engaged in nanomaterials such as graphene.

The level of authority here is second only to the office of the CEO of each subsidiary of Source Shadow International Group.

In addition to the researchers working here, the employees of the entire Source Shadow International Group who can enter here can be counted on one hand.

The entire laboratory cost 200 million US dollars, which is currently the most expensive laboratory of Yuanying International Group.

Although it is a burning of money, the $200 million investment is already a lot of money savings compared to other laboratories around the world that study nanomaterials.

Many experimental instruments often burn millions of dollars, and the cost and maintenance costs are amazingly expensive.

The reason why the laboratory of Source Shadow International Group saves money is thanks to the industrial-grade 3D printer brought by Xu Yuan, and many cutting-edge experimental equipment can be produced by itself.

The scientists standing here may not be the best scholars in their field in the world, but they are exposed to the strongest technology in the 21st century.

When Xu Yuan arrived at the laboratory, the director of the laboratory, dressed in a white lab coat, was standing with other staff members, gathered around an experimental equipment, nervously conducting experiments on nanomaterials.

Some are responsible for adjusting parameters, some are responsible for recording data, and some are responsible for evaluating phenomena.

There are a total of fifteen researchers here, and none of them are superfluous.

The director of this laboratory is named the former academician of materials physics of the Chinese Academy of Sciences.

It was not easy to invite him to be the director of the laboratory.

Although the income of scientific researchers in China is not high, they will not be paid low when they reach the level of academicians of the Chinese Academy of Sciences, especially in the research direction of materials science, which is linked to national defense.

According to Liu Feng's own statement, counting bonuses and social security, he probably has a salary of one or two million a year.

However, Xu Yuan's annual salary is 10 million.

Facts have proved that as long as the hoe is swung well, there is no corner that cannot be dug down.

However, what really attracted this old professor to bring a few of his protégés to Qatar was the free scientific research environment promised by Xu Yuan, the most cutting-edge scientific research equipment, and the most attractive technical information of Yuanying International Group.

Of course, non-disclosure agreements are also indispensable.

Since he came here, Xu Yuan naturally wouldn't let him go again.

Standing quietly in the corridor outside the laboratory door, Xu Yuan watched through the window as these scientific researchers tinkered with experimental equipment, and waited until the experiment was over before opening the door and walking in

"How's it going?"

"Ideal." Liu Feng patted the experimental data book in his arms and sighed to him. "I finally understand now how terrible the scientific research strength of Source Shadow International Group is."

"Can I interpret this as boasting about you?" Xu Yuan said in a joking tone.

Liu Feng smiled and handed over the experimental data to his assistant. instructed him to do a good job of summarizing the experimental data, and then looked at Xu Yuan again.

"I was shocked, such a high-strength graphene cable, I never thought I would be able to see it in my lifetime, with it, I am afraid that the space elevator that will only appear in novels and movies is not a difficult thing."

In the instrument cover in the center of the laboratory, a thin graphene tube is connected between two metal columns, and this "hair strand" is the laboratory.

Just now, they tested the strength of this graphene tube in different air pressures and gas environments, and the results obtained are also very gratifying.

"The space elevator is our next step in strategy, and I can tell you in advance." Xu Yuan smiled.

Most people know that graphite is one of the softest substances in nature.

What most people don't know, however, is that the so-called "soft" is only a macroscopic phenomenon.

Like a hexagonal grid stacked layer by layer, the graphite interlayer structure is maintained by the "most unreliable" van der Waals force, so it is very easy for the layers to "slip" under the action of external forces, thus giving people the illusion of "soft".

But in the perpendicular direction, graphite is amazingly "hard"!

According to the latest research results, the maximum pressure that graphene can withstand per 100 nanometers reaches 2.9 micronewtons.

That is, 55

It takes 1 meter of graphene to break! Intuitively speaking, the thickness is equivalent to the graphene of a food plastic packaging bag, so it takes almost 20,000 oxen of pressure to tear it off.

In other words, if a bag is made of graphene, then it will be able to withstand a weight of about two tons!

Here we only talk about its strength, not its conductivity, light transmittance, extremely light weight and anti-weather performance of sterilization and disinfection.

It is precisely for this reason that graphene is one of the key research topics in countries around the world.

From space elevators to supercomputers, from next-generation photonic sensors to next-generation mobile phone screens, this new material, which is simple to source but cumbersome to prepare, has been favored all over the world at the beginning of this century.

It can be said that graphene materials are the future!

In this regard, Yuanying International Group can be said to be at the forefront of the world.

Although it has not been disclosed, in many products, Yuanying International Group has used graphene materials.

For example, the shadow of graphene materials can be seen in the mechanical exoskeleton device currently used by Xingyuan Trading Company, from the access chip to the detachable polyethylene bulletproof panel.

Another example is the Phantom helmet and the electromagnetic acceleration orbit of a seabed mining facility, which are made of graphene material.

However, the application is one thing, these products are designed from the source star, which does not mean that the source film international group has thoroughly mastered these technologies.

In order to digest the technologies brought from Yuanxing and apply these technologies in a wide range of fields, Xu Yuan still invested in the establishment of a graphene laboratory, and invited a group of scientists who have made achievements in the field of graphene research to digest and experiment with these advanced technologies.

And Liu Feng really did not live up to his expectations.

With that "hair strand" back to the source star, after the inspection of scientific researchers, it has reached the quality standardization required for the construction of the space elevator.

This indicates that in terms of materials science, the technology of Yuanying International Group has been leading the world for at least 20 years!
