"Forget this, I'm actually very grateful for you, but I appreciate your kindness." Chen Yuan was a little surprised. He didn't expect the main star to give such an answer.

After all, the main star is actually a very lonely person, and he should hope that someone will support him.

"I hope that the brain can make them voluntarily stop using it, rather than using forced means." Chen Yuan could understand that the main star is indeed amazing.

Regarding space elevators, Fusang has long said that a special elevator will be built in 2050. Not to mention this technical problem, Fusang's current financial resources problem is just the current issue.

After all, there are few projects in this century, and it will cost hundreds of billions of dollars. Now there are only three United States that have the real financial and technological advantages.

According to scientists' predictions, the most important part is the development of cable parts, because these cables connecting space and the ground need to resist strong winds and even aircraft impacts.

Chen Yuan smiled, "When reading the novel Three-Body Problem, a fairly reasonable solution was given. In the novel, the academician of Qinghua University designed a carbon nanomaterial called Feiren. This material is thinner than hair, but extremely tough, and directly cut the Trial Rebel Party's Day of Judgment into several pieces."

"There are all members' heads and heads, and the strength of this material can be seen."

"So can we make this kind of material in reality?" Lu Jian said anxiously.

"Of course, didn't I say that before, we had carbonaceous materials." Chen Yuan said, "It can be made into carbon fiber nanomaterials."

"Carbon fiber nanomaterials have very small density, strong tensile resistance and can reach 300 typhoons. The length we need is at least 36,000 square meters.

As for the unrestrained and complicated elevator operation, it is also very complicated. In the art of Paradise Fountain written by the author Arthur Clark, the space elevator uses the old-fashioned hub elevator to pull people into space before it is powered on. The speed is very slow and even takes several days.

In reality, this method is definitely not allowed to go to space. Currently, there are two main solutions for driving space elevators.

The first one is to add wheels to the entire liftoff elevator, so that the wheels can be added with cables, and the electricity on the cables can reach the earth's orbit directly.

In this way, the elevator can reach the sky as fast as the electric-driven high-speed train.

However, this space cable is tens of thousands of meters long, and whether it is from the ground or from the space station, it may slow down due to resistance. Therefore, to ensure that the space elevator is full of power, we need to add a layer of superconducting material to the cable.

However, humans have not yet done the superconducting materials at room temperature, so we may have to hang several generators on the space elevator.

In the atmosphere we can use helium fan engines, and outside the atmosphere we can use solar panels, but this will obviously increase the load capacity of the space elevator.

The other is to clamp two solar cells on the elevator. The power of going up and down from the sky and down the ground comes from the strong laser beams on the space station and the ground. This method seems unreliable, but someone has already implemented it.

In 2009, in most energy challenges in the state, a scientific team used strong lasers to send a lift equipped with solar cells to an altitude of 900 meters.

Unfortunately, this speed is only 3.9 meters per second. In the construction of space ladders, laser propulsion needs to consider the distance of nearly 4 meters and laser scattering, and its speed cannot be too slow.

Then the laser light is big and it is the Ark Reactor.

"However, given the location of the sea-facing transportation hub where the space ladder is located, I do not support the establishment of large nuclear power plants."

If there is an elevator such as earthquake and tsunami, he might be able to hold on, but the nuclear power plant may repeat the tragedy of Fukushima.

"So it's better to use cables to get it over it."

"But next we need to solve the space station and location selection of the space ladder." The space ladder is something that is stationed on the ground in most cases, so the space station at its top must also be relatively fixed. Therefore, the location of the ladder space station must be on a synchronous stationary orbit, that is, above the equator 36,000 kilometers away from the surface.

Kepler is almost the same as Earth.

The equator is the closest area to the synchronous orbit, but only two launch sites adjacent to the equator do not belong to the equator.

Most of the simple equatorial areas are in the sea, while Kepler's only equatorial countries are worried about their economic and technical levels. In short, there is no one who can fight.

After all, this civilization is not only the country where the main star is located.

Based on this situation, if you want to establish a space ladder, you must cooperate with the equatorial area and first establish a port of ​​Feng. The port of ​​Ship will become a base station and transportation hub for space elevators.

At the same time, the area must be close to the sea and have relatively developed water and land transportation.

This is not a problem. Anyway, people on this planet are crazy about the brain-tight technology. They will definitely agree with Chen Yuan's coercion and temptation.

Next, there is a problem of space construction. The cable of a space elevator will be subjected to two forces that pass through the gravitational force from the ground below the orbit and the centrifugal force pulled from space on the synchronous orbit.

Therefore, we should build two space stations, namely, a synchronous orbit orbit, as the intermediate station where the spacecraft satellites stop by the port, and a counterweight space station on the top of the space elevator is responsible for increasing the balance between centrifugal force and ground gravity.

According to my design, the berth is located in a synchronous orbit of 36,000 kilometers. At this location, spacecraft and satellites can orbit Kepler for a long time, so this is also a good place to build a space city and a space dock.

The Yellow River Station in the Three-Body Alley is full of such supporting facilities, but these docks in space are a certain distance from the berthing port to avoid affecting the stability of space ships.

While providing counterweights and building an additional power station should be located higher than synchronous tracks.

Considering the gravity from the ground, this station requires a large mass, which can use solar panels and power generation systems.

Once this is built, the space port built in advance on this basis can be built on this basis and it can play a role."

Most of the people in the planetary defense team that Chen Yuan talked about in detail at the meeting supported his decision, after all, they didn't understand such things.

The real decision is not Chen Yuan. People know more than them, so you can't just give it any trouble. You can't just give some advice on something you don't understand.
