The Return of the Black Technology of Immortal World

Of course, it is still 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 orbited the sun was in 1986, and its next visit will have to wait until 2061.

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

According to some reports that are not sure whether they are true or not, there are nearly a thousand microcomets that disappear in the Blue Star's atmosphere every day.

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

However, as Xiao Ai fully activates, the speed of various spaceships will rapidly increase to one-fiftieth or even one-tenth of the speed of light. At that time, traveling to and from Ke Yinbo Belt will not be that difficult.

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

Because there are not only a large number of asteroids here, but also a lot of asteroids containing more ice. The most important thing is that it is close here.

A round trip to the Kuyinbo belt is enough time to travel back and forth to the asteroid belt several times.

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

Of course, to achieve the idea of ​​capturing comets or asteroids, there are still many things that Xiaoai needs to do, such as a suitable towing rope, or simply using the speed of light due to gravity.

The towing rope Xiaoai chose carbon nanotube material. This carbon nanotube material has amazing tensile strength and is the cable material of the space elevator in many science fiction novels.

If Yang Qing had not discovered the secret of controlling gravity, or building several space elevators on Blue Star would be the best way to transport materials into space.

The properties of carbon nanotubes have been discovered decades ago, and a large number of samples have been produced in laboratories.

However, currently single-walled carbon nanotubes still cannot be made very long, which is also the biggest obstacle in the application of this material that performs extremely well in all aspects.

However, the Moon Palace Base successfully broke through the obstacles in the production of single-walled carbon nanotubes. The most important thing is that in this process, not many things from the runes were used, and even if they were, they were in a auxiliary state.

Or this can be regarded as a major breakthrough from Blue Star's production technology, because Blue Star has studied the principles very thoroughly and explained several methods clearly.

It's just that Blue Star's factory lacks the ability to control various variables in the production process and is unable to produce suitable products.

In the Moon Palace Base, there is the biggest cheating device, which is Xiao Ai's spiritual consciousness and Yang Qing's spiritual consciousness.

For example, when the arc discharge method is used for production, their spiritual consciousness can even track the landing point of each arc, its effects, and how to improve it.

Yang Qing is relatively busy, or may not have time to pay attention to the improvement of this kind of technology, but Xiao Ai has huge spiritual knowledge, as well as massive calculation and reasoning abilities.

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

Although the level of these college graduates in the family varies greatly, and it is difficult for them to lead a process improvement independently, they are all college students, and their knowledge reserve is still sufficient. 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, you are quite competent as a commander.

As for those who take action, they are all robots. Although they are all under the direct leadership of Xiao Ai, in fact, most of them have primary artificial intelligence chips, and they can also temporarily borrow computing power from the central computer room.

The biggest feature of these robots should be their absolute stability. If you think about it, as long as you follow the procedures, it is difficult for them to make mistakes.

Under this condition of humans using their brains and mouths, and robots using their hands, equipment that can continuously produce carbon nanotubes was built directly, and the defects on the carbon nanotubes have been reduced to the level of twelve nines.

This level is actually nothing. Most of the materials in the base are purified to a level above eighteen to twenty nines.

The iron, lithium, copper and other elements sent from the moon to the Blue Star are all at this level and can be said to be pure metals.

It’s 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 material is almost five meters per minute. If the processing technology is improved and defects are reduced, the production time of one meter of material will be 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 is actually sharper than most knife blades.

I remember that there was a plot in Three-Body Problem, which was Operation Guzheng against the Three-Body Blue Star organization.

The whole plan is to erect a few steel pillars on both sides of the canal, and string a few flying blades between the steel pillars, just like a guzheng.

In this way, with 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 flying blade material should be carbon nanotube material.

Because although the flying blade is called a nanomaterial, its diameter should actually be around microns. For such materials, the only materials that meet the requirements should be carbon nanotubes.

If only one carbon nanotube is used, it is not known whether it is dragging the asteroid or cutting it.

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

Because this kind of material is most afraid of all kinds of friction, especially on asteroids, it is inevitable that there will be materials that are not inferior to it in hardness.

Therefore, carbon nanotubes must be wound up in 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 full-length one, so its tensile strength calculation requires at least the tensile strength of hundreds of thousands of carbon nanotubes superimposed on calculated together.

Although there are more than 100,000 of them, its diameter is only a few centimeters thick, and its tensile strength exceeds 200gp. Hundreds of thousands of them are stacked together. If you want to use it to pull a weight of several million Ton asteroids seem to have no difficulty at all.

In fact, for actual application, 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.
