Vol 3 Chapter 281 carbon nanotubes

Of course, it is still relatively difficult to directly capture a large comet with a diameter like the famous Halley’s Comet, because its mass is still too large and its speed is too fast.

The last time Halley’s Comet circled the sun was in 1986, and its next visit will not be until 2061.

In the solar system, there are actually not many comets, but most of them cannot be observed by ordinary telescopes or naked eyes. For example, there are not many comets that are brighter than most planets.

According to some unknown reports, the number of micro comets disappearing in the blue star’s atmosphere every day is nearly a thousand.

Although basically no comets exist in the asteroid belt, their home base is in the outer solar system’s Kuiper belt, and there are many, which do not orbit the ecliptic plane.

However, with Xiao Ai’s full power, the speed of various spaceships will rapidly increase to one-fiftieth, or even one-tenth of the speed of light. At that time, it will not be so difficult to travel to and from Ke Yinbo’s belt.

But before that, their main target was the asteroids in the asteroid belt.

Because there are not only a large number of asteroids here, but there are actually not many asteroids with a lot of ice in them. The most important thing is that it is near here.

The time for a round trip to the Keyinbo belt is enough to go back and forth several times in the asteroid belt.

There is even room to pick and choose here, find some asteroids that are not that big, and directly smash them on Mars, saving the trouble of segmentation.

Of course, to achieve the idea of ​​capturing comets or asteroids, Xiao Ai still needs to do a lot of things, such as needing a suitable towing rope, or simply using the gravitational light speed.

Xiaomei chose carbon nanotube material for the drag rope. This carbon nanotube material has amazing tensile strength and is the cable material for space elevators in many science fiction novels.

If Yang Qing hadn’t discovered the secret of controlling gravity, or building a few space elevators on Blue Star, it would be the best way to transport materials into space.

The properties of carbon nanotubes have been discovered for decades, and large numbers of samples have been produced in laboratories.

It’s just that single-walled carbon nanotubes still can’t be made very long at present, which is also the biggest obstacle in the application of this kind of material that performs extremely well in all aspects.

However, the Moon Palace base successfully broke through the barriers of single-walled carbon nanotube production. The most important thing is that in this process, they did not use too many things from runes, and even if they did, they were still in an auxiliary state.

Or this can be regarded as a major breakthrough in the production process from Blue Star, because in terms of principles, Blue Star has already studied it very thoroughly, and several methods are very clear.

It’s just that Blue Star’s factory has insufficient control over various variables in the production process, so it cannot produce suitable products.

In the Moon Palace base, there are the biggest cheating tools, namely Xiao Ai’s spiritual consciousness and Yang Qing’s spiritual consciousness.

For example, when using the arc discharge method for production, their spiritual consciousness can even track the landing point of each arc, as well as the effect and how to improve it.

Yang Qing is relatively busy, or doesn’t have time to always pay attention to the improvement of this kind of craftsmanship, but Xiao Ai has a huge amount of spiritual knowledge, as well as a massive calculation and reasoning ability.

After a month of continuous testing regardless of cost, she found the most efficient and best quality carbon nanotube production process.

Although the college graduates in the family have uneven levels and it is difficult to preside over a process improvement independently, they are all college students, and their knowledge reserves are still good. At least in the environment of the Moon Palace Base, they also have enough enthusiasm for learning.

So as long as you don’t let them get started, as a commander, you are quite competent.

As for the hands-on ones, they are all those robots. Although they are all under Xiao Ai’s direct leadership, in fact, most of them have elementary artificial intelligence chips, and they can temporarily borrow computing power from the central computer room.

And the biggest feature of these robots should be their absolute stability. One thing to think about, as long as they follow the procedures, it is difficult for them to make mistakes.

Under the conditions of human beings using their brains, mouths, and robots, the equipment that can continuously produce carbon nanotubes has been built directly, and the defects on carbon nanotubes have been reduced to the level of twelve nines.

This level is actually nothing. Most of the materials in the base have a purification level of more than eighteen to twenty nines.

The elements such as iron, lithium and copper sent from the moon to the blue star are all at this level, and they can be said to be pure metals.

It is not that more perfect materials cannot be produced, but that continuing to reduce defects will lead to a reduction in production efficiency.

Now, the production speed of this kind of material is almost five meters per minute, but with the improvement of processing technology and the reduction of defects, the production time of one meter of material has directly increased to one hour.

If you use it as a rope, you don’t need to be so thin, because the diameter of a carbon nanotube is only 6 to 7 nanometers. This diameter~www.readmtl.com~ is actually sharper than most knives.

I remember that there is a plot in the Three-Body Problem, which is the Guzheng operation against the Three-Body Blue Star Organization.

The whole plan is to erect a few steel pillars on both sides of the canal, and draw a few flying knives between the steel pillars, just like a zither.

In this way, with the help of the speed of the cruise ship, it was cut into more than forty slices with a thickness of fifty centimeters.

According to experts’ calculations, this kind of flying blade material should be carbon nanotube material.

Because although the flying blade is called a nano-material, its diameter should be around a micron. Such a material should only meet the requirements of carbon nanotubes.

If only one carbon nanotube is used, then it is not known whether to drag the asteroid or cut it.

To drag an asteroid, the pulling force of a carbon nanotube is still a bit lacking, and it is not so powerful to cut an asteroid.

Because of this kind of material, the most feared thing is all kinds of friction, especially on asteroids, it is inevitable that there will be materials whose hardness is not inferior to it.

Therefore, carbon nanotubes must be wound in several groups like hemp rope, and braided into a thick enough cable for use.

And it is very different from ordinary hemp rope, because its silk thread is a long one, so its tensile calculation is to superimpose the tensile strength of at least hundreds of thousands of carbon nanotubes on the calculated together.

Although its number exceeds 100,000, its diameter is only a few centimeters thick, and its tensile capacity exceeds 200GP. Hundreds of thousands of them are stacked together, and they want to use it to pull a weight of several million Tons of asteroids, there seems to be no difficulty at all.

In fact, for practical use, the diameter of the rope must be at least fifty centimeters, and it must be woven into a rope net. Otherwise, compared to the size of the asteroid, this rope is not much different from a knife.
