Is it reasonable for me to build a space elevator when filming The Wandering Earth?

After a series of speculations in their hearts, the consultants of these space centers have determined that the crew of "The Wandering Earth" is shouldering an important scientific research task.

By the time Shi Lei arrived at the filming base of "The Wandering Earth", four carbon nanotube cables had been connected to the ground-end pedestal located inside the filming base.

The launch vehicle, which has been launched into outer space, acts as a counterweight module for the space elevator, pulling four carbon nanotube cables straight.

The launch vehicle is located in a synchronous orbit, at this time its operation is like a chain ball movement, the earth is like an athlete, and the launch vehicle is like an iron ball that is pulled.

As long as its centrifugal force in the synchronous orbit is greater than gravity, the space elevator's car can steadily ascend and descend through a carbon nanotube cable.

The next step is to build a space elevator cabin that can carry people and goods up and down.

While Liu Lang was making preparations, Shi Lei finally came to him.

"Mr. Liu, you're making a big news for me!

This carrier rocket was originally said to be a movie prop, how can you really launch it?!"

In the face of the expected questioning, Liu Lang did not panic.

"Colonel Shi, have you seen my short film, "Space Elevator Battle"?"

"I've seen it, what's wrong?"

Hearing Liu Lang change the topic, Shi Lei looked puzzled, as Liu Lang's masterpiece, of course he had seen the video "Space Elevator Battle".

"In the video, I designed a building that can reach outer space from the ground, a space elevator.

It is capable of transporting people and supplies to outer space at a fraction of the cost.

Listening to Liu Lang's introduction, the puzzle on Shi Lei's face became more and more serious, of course he knew the significance of the space elevator, too many experts and scholars on the Internet had already carried out popular science.

However, it was difficult to build a space elevator, starting with the material.

With the technological level of human beings in the real world, it is simply impossible to solve this problem in a short period of time.

"Mr. Liu, we are now talking about the launch vehicle that you launched into outer space. "

That's right, it's an important part of my plan to build a space elevator!" Liu

Lang pointed to the ground base of the space elevator not far away, located in the shooting base.

Shi Lei followed the direction of Liu Lang's finger, and only then did he find four inconspicuous carbon nanotube cables.

They were tightly connected to the base of the ground, straight and taut, reaching upwards into the sky.

"It's...

"A high-strength cable made of carbon nanotube material that connects the ground base of the space elevator to the upper counterweight module.

At the top of them at the moment is the launch vehicle. Hearing

Liu Lang's explanation, Shi Lei finally reacted.

"You built that space elevator thing?!"

Shi Lei looked at the four carbon nanotube cables with a shocked face, if Liu Lang didn't lie to him, with the rigid strength of these four cables, it means that the most difficult material problem for building a space elevator has been solved.

"To be exact, there is still a car missing.

"You wait, let me slow down.

Shi Lei's heart beat wildly inexplicably, and he looked up at Liu Lang, feeling more and more unfathomable that the other party was unfathomable.

Although he is not an expert in materials science, Shi Lei, as the head of the security department, has been exposed to many cutting-edge scientific research projects in the country.

Carbon nanotubes, which are only one-sixth the density of steel, more than 100 times the tensile strength of steel, and have so many amazing properties, are currently only produced in small quantities in the laboratory.

And Liu Lang was able to make it into a cable from the ground end to the space end, which means that he has mastered the technology of mass production of carbon nanotube

materials!"Are those prop factories

?!You are ready to do this?!"

Shi Lei realized why Liu Lang needed such a large amount of industrial raw materials when he asked for it.

"That's right!"

"Why are you building this? Space elevator?"

"I'm a science fiction director to make a movie.

"The Wandering Earth" is a hardcore sci-fi film, and I make some live-action building props, which is very reasonable, right?"

Liu Lang said to Shi Lei seriously.

"This sci-fi movie is really hardcore.

Shi Lei swallowed with difficulty, this is not the first time he has heard Liu Lang seriously say that he is a director.

Despite the identity of the other party, it is indeed a college student in the directing department of the film school who graduated not long ago.

But the drone technology, exoskeleton armor technology, and the half-finished space elevator in front of him all made Shi Lei, who thought he was used to seeing the world, feel very unbelievable.

"I'm sorry, I'll have to go out and ask for instructions. "

As a widely used material, the industrial mass production technology of carbon nanotubes is of great strategic significance to the country.

If what Liu Lang said is true, then the technology he has mastered is far beyond the scope of Shi Lei's authority to deal with it alone.

Looking at the back of Shi Lei leaving in a hurry, Liu Lang couldn't help but let out a long breath.

。

Early the next morning, Liu Lang didn't wait for Shi Lei, but the assistant director Lin Hao ran over with a heavy heart.

"Brother Lang, our crew won't be a crime, right?"

"Hmm?!"

Liu Lang didn't understand what Lin Hao meant for a while.

"There seem to be troops patrolling around our base, they don't wear uniforms, but the way they walk is obvious to me at a glance, and the underneath the clothes are bulging, and they look like firearms.

Two coast guard ships with a displacement of seven or eight thousand tons came to the port in the morning, saying that they were temporarily berthing for supplies.

They simply took me for a fool, not to mention how long this port has been abandoned, how can there be a coast guard ship equipped with rapid-fire close-in defense guns and vertical missile launch compartments?!"

The filming base is huge, covering an area of more than 40 square kilometers. The actors who live in it, the staff can't notice the strangeness around them for the time being.

But as the assistant director of the crew of "The Wandering Earth" and the logistics housekeeper, Lin Hao is still keenly aware of the changes around the filming base.

"Don't worry, if you're lucky, maybe in a few days there will be a large number of professional army extras into the group, and those two coast guard ships can be borrowed for filming. Liu

Lang is most concerned about the problem of the actor's contract being stuck, if this problem is not solved, the crew will not be able to enter the normal filming stage.

Since the competitor uses the card contract as a shady trick that can't be put on the table, then don't blame him for making some bigger moves to 'reduce the dimensionality'.

Lin Hao didn't believe it at all after hearing this, with an expression that you were talking in your sleep.

After thinking about it, he analyzed that the movement of the 'Sky Monkey' was too big, which attracted the attention of the official and even the military.

In a sense, he guessed correctly.
