This means that from now on, the space elevator cables we produce will no longer require the use of rope weaving methods to make longer cables.

We just need to slightly twist and rotate countless single-walled carbon nanotube lines to form a cable.

Compared with the original structure, this structure can withstand the greatest pressure and has the smallest volume.

Of course, in addition to being able to withstand greater pressure, the biggest advantage is that it has better conductivity, lower power loss, is not afraid of lightning strikes, can be used in storms, etc. ”

Hearing Lin Feng's words, the people at the scene brightened up.

Those who have some scientific knowledge or are in the field of scientific research themselves become particularly excited.

Because if single-walled carbon nanotubes can really reach a length of 4 kilometers, then the role of single-walled carbon nanotubes will be enormous.

However, Lin Feng did not stop talking. What he said next caused the people at the scene and the netizens in the live broadcast room to fall into an uproar.

Lin Feng continued to speak under the gaze of the people:

“The new cable brings greater strength, which can be increased by increasing the cable width.

As for the width of our second-generation space elevator system?
The width of our space elevator cable is 300mm. It can pull the Tiangong space station while supporting the operation of the elevator carrying tens of thousands of tons of materials.

Of course, in reality, we will not really load tens of thousands of tons of supplies, because if we do so, the pressure on one point of the cable will be too great.

Therefore, we adopt the form of segmented transportation, that is, dividing tens of thousands of tons of materials into multiple parts, and then distributing the pressure equally to multiple nodes of the cable.

Ultimately, it will reduce the pressure on a certain node, enhance security, increase lifespan, and so on.

Of course, it is worth mentioning that our future Tiangong space station will not have only one cable, but actually hundreds of cables.

The reason for adopting this model is to facilitate the timeliness of material transportation and improve comprehensive transportation capacity.

As for how much weight a single elevator can bear, the upper limit of the weight that the elevator we designed can bear is 2500 tons!
That is to say, a single elevator can transport 2500 tons of materials to the Tiangong Space Station in space at one time."

"Wow!"

After hearing Lin Feng's words, the scene was instantly thrown into an uproar, and people's eyes were all wide open.

Because what did they hear?
Lin Feng actually said that a single elevator of the second-generation space elevator can transport 2500 tons of materials at a time?

This is a huge number, considering that a car weighs only a few tons.

Even if we add a little weight to it, converted into two tons, it means that it can pull 1250 cars at a time!
That's an amazing transport capability!

Of course, it is actually impossible to transport 1250 cars at a time.

This is because cars take up a lot of space. If 1250 cars were crammed together, the space they would take up would be too large to be transported all at once.

But even so, the transportation capacity is quite amazing.

It can be said that with this amazing transportation capability, there is no need to worry about either the Tiangong City Project or the Skynet Project.

After all, the carrying capacity of a single elevator in the original first-generation elevator system was only as big as a table, and the total weight did not exceed 500 kilograms.

Therefore, you can only disassemble the equipment into very small parts and finally assemble it in space.

Now, even a tank or an armed helicopter can be transported there. In this case, the large-scale Skynet satellite system with surveillance cameras and network communication functions can naturally be put up through the space elevator system.

The same goes for the components of the sky city. Components as large as a house can be transported directly up via the space elevator system.

In this way, the construction speed of the space city will be greatly increased. As long as the production capacity on the earth can keep up, the Tiangong City can be built quickly like building blocks.

Faced with this situation, how could people not be shocked and outraged?

However, Lin Feng's introduction was not finished. In the following time, Lin Feng continued to introduce various aspects of the second-generation space elevator system.

For example, the envisioned Tiangong City will have hundreds of cables, and a large amount of materials will be transported back and forth via space elevators at all times.

It can be said that through Lin Feng’s explanation, people were shocked to find that this second-generation space elevator system is already quite mature.

If the experiment is really successful, then humans can build spaceships in space, and it is not impossible to build a city in space.

Of course, for ordinary people, if this second-generation elevator system passes the test, then if they want to travel to Tiangong City in the future, the cost will be really low.

After all, the transportation capacity of the second-generation space elevator system is too powerful, and the transportation capacity is too strong.

Finally, it only consumes electricity, so transporting tourists to Tiangong City for tourism is naturally nothing. It is estimated that only a few hundred yuan for tickets will be needed.

Of course, the press conference is not just about introducing the second-generation space elevator system.

After the introduction of the second-generation space elevator system, the next step was to introduce the first-generation supercapacitor.

"The next thing I'm going to introduce is the first generation of supercapacitors."

At this point, the image on the projection screen behind Lin Feng suddenly changed to a diagram introducing the structure of the first generation supercapacitor.

"As you can see, this is a first-generation supercapacitor, made up of countless 4-meter-long single-walled carbon nanotube wires plus other materials."

At this point, Lin Feng said with deep emotion:

“Before the emergence of the first generation of supercapacitors, the boundary between batteries and capacitors was always clear.

Capacitors have super fast charging and discharging capabilities, but their energy density is very low.

Although batteries do not have the performance of fast charging and fast discharging, they have a high energy density.

Now, our first generation of supercapacitors breaks the boundary between capacitors and batteries, blurring the positioning of the two.”

Hearing Lin Feng's words, the people at the scene showed curious expressions in their eyes.

Judging from what Lin Feng said, could it be that the first generation of supercapacitors to be released this time will have an energy density far exceeding that of current batteries?

As their curiosity grew, Lin Feng smiled and said:

“I say this because our first generation of supercapacitors has successfully surpassed all batteries on the market in terms of energy density.

Although more powerful batteries may appear in the future, we have to admit that in this era, our first generation of supercapacitors has blurred the positioning of capacitors and batteries. "(End of this chapter)
