It can only be said that it is wrong for netizens around the world to admire the behavior of the American empire. They should actually feel angry.

After all, their money will invisibly depreciate faster due to the construction of the space magic network system by the US Empire, and the interest on their money deposited in the bank will not be as fast as the depreciation rate.

At this time, they should naturally feel angry rather than admiring.

But unfortunately, netizens can only see more direct things. They cannot see the hidden financial tricks and are powerless to influence them.

But no matter what, the United States announced that it would build a space magic network.

This still puts great pressure on Daxia and Xingtu Technology.

After all, the two sides are now in a competition to see who can occupy more pits first.

If you slow down a step now, it will mean you will have one less space orbital position in the future.

Finally, the people of Daxia are paying close attention to this matter, hoping that Daxia can surpass the American Empire and take the lead in building a space Skynet system.

Under such circumstances, how could Daxia and Xingtu Technology not feel tremendous pressure?

However, although the pressure was great, Lin Feng was not very panicked.

Because the space elevator system is essentially a product, it naturally has an upgrade panel that can be upgraded, and the current experience is already sufficient.

The reason why Lin Feng has not chosen to upgrade so far is because the space elevator system is already in front of people all over the world.

Countless satellites, cameras and even countless pairs of eyes around the world are watching the space elevator system.

If Lin Feng upgrades the space elevator system, and then the space elevator system suddenly collapses into countless fragments and then reassembles, the world will probably fall into a panic.

Because that scene was extremely unscientific, and it was a technology that was completely impossible to achieve with Earth's technology.

If humans wanted to achieve that kind of technology, they would probably have already dominated the Milky Way.

So although he had enough experience to upgrade, Lin Feng had not yet upgraded the space elevator system.

At this time, as the United States Empire was confronting each other head-on, it announced that it would build a space magic network system.

Lin Feng knew that he had to upgrade to the second-generation space elevator system.

He needs to use a more powerful second-generation space elevator system to improve the transportation capacity of the space elevator, so as to quickly complete the space city plan and the space Skynet plan.

With this mentality, Xingtu Technology's processing plant and other cooperative production factories immediately started operating.

Then, in just half a month, relying on the huge production capacity of Xingtu Technology and Daxia, an identical first-generation space elevator system was urgently produced.

However, what is different about this space elevator system is that they are all piled together now.

Looking at the first-generation space elevator system in front of him that required 6000 million experience points to upgrade, Lin Feng sighed that the experience points required for the upgrade were too low, and directly issued the upgrade order.

"Upgrade."

As Lin Feng spoke, the components of the first-generation space elevator system in front of him suddenly began to disintegrate.

Then, accompanied by an inexplicable strong wind, the components of the second-generation space elevator system in front of them began to condense.

On the other hand, the various metal elements and carbon elements that had been prepared long ago also began to gradually disappear. They were filled into the condensing second-generation space elevator components using atomic-level printing technology.

Finally, the inexplicable wind stopped, and the components of the second-generation space elevator system finally revealed their true appearance.

"This……"

Looking at the second-generation space elevator system components in front of him, Lin Feng's eyes flashed with ecstasy.

Because Lin Feng discovered that the technology carried by this second-generation space elevator system unexpectedly solved the key technical problems of the new super battery. According to the knowledge in his mind, the cable used by this second-generation space elevator.

It is not like it is now, relying on the rope weaving method to weave countless single-walled carbon nanotubes with a length of no more than 200 meters into a cable.

The reason why this second-generation space elevator is currently worth 6000 million experience points.

A large part of the reason is that it successfully broke the length problem of single-walled carbon nanotubes.

Based on the knowledge in his mind, Lin Feng discovered that the length of the single-walled carbon nanotube actually reached 4 kilometers, instead of the original length of no more than meters!

What does this mean?
This means that the width of the cable can now expand infinitely!

All you have to do is twist and turn them a little bit, and you can create a space elevator cable the width of a computer desk without any problem.

Because its length can reach 4 kilometers. Compared with the length of 4 kilometers, the width of a computer desk is still very "thin".

Given the extraordinary strength of single-walled carbon nanotubes, the tensile strength of a cable the width of an office desk is simply unimaginable.

Of course, the second-generation space elevator in front of us does not use such a width, because there is no need for it.

The actual cable width is only 300mm.

This is because the second-generation space elevator system does not have just one cable, but dozens or even hundreds of them.

The ultimate goal is to pursue greater and more flexible transportation capabilities.

After all, if you only have one cable, the transport capacity is limited.

On the contrary, if there are multiple cables, the material transportation capacity and flexibility will be greatly improved.

As for the load-bearing capacity of a single 300mm cable?

The 300mm cable has a load-bearing capacity that allows it to carry the elevator carrying tens of thousands of tons of supplies while pulling the Tiangong space station.

Of course, in reality, the actual carrying capacity of this elevator will not really reach the level of ten thousand tons of materials. A single elevator can only carry a maximum of 2500 tons of materials.

The reason is that the gravity of tens of thousands of tons of materials is concentrated in one place, which puts too much pressure on the cables and elevators.

So the actual situation is that tens of thousands of tons of materials will be evenly distributed, resulting in an elevator every certain distance.

This way, the pressure on the cables and elevators will not be as great and it will be safer.

Of course, what surprised Lin Feng was not that the carrying capacity of the second-generation space elevator cable had increased countless times.

Instead, the length of single-walled carbon nanotubes reaches 4 kilometers.

Because when the length of carbon nanotubes reaches 4 kilometers, its prospects suddenly expand.

Take supercapacitors as an example. Previous supercapacitors had very limited practical uses because the length of single-walled carbon nanotubes was too short.

But now it is different, because the longest length of single-walled carbon nanotube lines has reached an astonishing 4 kilometers.

Then it can go directly from the source to the end without the need for other conductive materials or liquid filling.

Ultimately, more than 4 kilometers of single-walled carbon nanotube wires can be packed into a small capacitor volume.

To achieve the same volume, the energy density of supercapacitors is increased countless times.

As for how much it can be improved, it depends on the specific results. (End of this chapter)
