The Black Technology Era of Xueba

First, low tritium retention and efficient use of tritium.

Tritium has a short half-life and is expensive, and all tritium in fusion reactors needs to be recycled.

Second, the ability to resist neutron and plasma radiation.

Each deuterium-tritium fusion produces an energy neutron, and these high-energy neutrons can easily break the metal bonds in the first wall material, resulting in a large number of defects, causing problems such as irradiation swelling, embrittlement, creep, etc. What material to use resistance to such irradiation;

Third, high temperature resistance and thermal shock resistance.

The working temperature of the first wall of the small fusion reactor is above 1000 ℃, and the instant the plasma bursts, it can reach 2000 to 3000 ℃. What material can resist this temperature.

Why can these problems be solved on the sun, but not in a ground laboratory?

Because the sun has strong gravitational confinement from the inside, and ground laboratories do not, it is necessary to use ultra-strong materials and technologies to confine high-energy particles.

The above three problems are the problems that Pangu Technology is currently facing.

Even if a device similar to Xia Guochao Tokamak is made, it can only achieve energy output, which is not cost-effective when measured by economic news.

"Super" here means superconductor.

At the press conference a month ago, Qian Yi only told the media that Pangu Technology had mastered the nuclear fusion technology, but did not say that it would be commercialized immediately.

This matter was mentioned at the press conference, which was more shocking than practical.

To put it bluntly, it means a bit bragging.

But if the bullshit blows it out, the thing will not be done? This is obviously not possible.

Controllable nuclear fusion technology is a project that Pangu Technology must win. This is a project that is related to future energy and even the future destiny of mankind.

So when the research was close to stagnation, Xiao Ming saw the medium technology catalogue about advanced controllable nuclear fusion technology.

Among the technologies of advanced controllable nuclear fusion, one of them is called gravitational creation.

This is too high-end. Out of curiosity, Xiao Ming exchanged surprise value for the gravitational creation in advanced controllable nuclear fusion technology.

Xiao Ming exchanged the Surprise Points in his hands for the Gravity Creation Technology. This time, all the Surprise Points were used up, and the commercial controllable nuclear fusion technology could not be exchanged.

But this exchange made Xiao Ming feel the real charm of the intermediate technology catalog.

It subverts Xiao Ming's imagination and subverts Xiao Ming's basic understanding of physics and the universe.

This exchange means that mankind has taken a solid step towards the ultimate law of the universe.

What is gravity?

For a long time, human scientists listed gravity as one of the four fundamental forces of the universe.

Gravity, electromagnetic interaction, weak interaction and strong interaction.

But in the long-term exploration, scientists found a very strange problem, whether in physical laws or mathematical models, gravity cannot be unified with the other three forces.

Until Einstein's theory of relativity was proposed, he believed that gravity was not a real force, but the effect of a mass object on the curvature of the surrounding space.

As we all know, a typical model is a small ball on the sponge, which can press the sponge down. And because the sponge is dented around the ball, and other things are placed, there will be a tendency to fall to the ball.

This model is analogous to the curvature of surrounding space-time by massive objects.

Therefore, Einstein believed that gravity is generated by the geometric bending of space, which itself can be said to be not a "force", but a geometric effect of space distortion.

However, when Xiao Ming created a description of gravity in the science and technology catalogue, he was shocked to find that Einstein's laws were not completely correct. Gravity could be unified with the other three forces. The description even explained the unification principle of Einstein's theory of relativity and quantum mechanics. (The current smooth space-time of general relativity contradicts the violent quantum fluctuations of space-time under the microcosm).

To put it more simply and clearly,

Einstein's conclusions are true in the familiar three-dimensional space, but not in higher dimensions.

In the manual, the four forces of the universe can even be unified with mass, which involves the basic constituent matter of the universe-superstring.

All things in the universe, including energy, are made of it, and superstrings are very small linear "strings". Different vibrations and motions of strings produce various basic particles. Energy and matter can be transformed. The vibration frequency of strings determines the types and properties of particles.

Gravity can be created by combining properties of superstrings.

After reading the manual, Xiao Ming's head went blank.

This is the real black technology.

The manufacture of gravity can not only perfectly complete nuclear fusion technology, but even change everything in the human world.

Suspended cars, suspended houses, etc...

This will be an extremely bright future technology.

However, Xiao Ming also clearly realized that there is still a considerable gap between theory and practice.

At present, this technology can be improved, but it is better to carry out nuclear fusion in the traditional way.

Thinking of this, Xiao Ming said casually, "Why can't we create gravity?"

Create gravity?

What a joke!

This can be a bold imagination! But it must not be possible.

What level of science and technology are human beings?

Create gravity?

After Xiao Ming said this, Xu Limin and the relevant experts from Xia Guo Energy Laboratory looked at Xiao Ming.

Xu Limin didn't know if Xiao Ming was joking.

Xu Limin said: "If we can simulate the internal environment of stars and create the gravitational force that constrains high-energy particles, then all the problems will be solved. However, we can only think about this matter. Create gravity? How to create gravity?"

Using his physical imagination, Xu Limin said: "Of course we can simulate magnetic fields or use centrifugal force to create so-called gravity, but at such a high temperature inside nuclear fusion, everything we do will be reduced to ashes, and these The force of gravity cannot compete with the energy of high-energy particles."

"Mr. Xiao's imagination is very rich! But as Professor Xu just said, there is no way to operate the actual situation, and the internal temperature is too high. If we can solve the problem of the temperature of the material, then there is no way to do it at all. The so-called creation of gravity is needed, and the super-tokamak device can be made directly from such materials.”

Everyone just took Xiao Ming's words as a joke and laughed.

Xiao Ming didn't get angry either, and he passed by happily, "Yes, the most urgent task is to find a way to optimize the super-tokamak device."

But back at the Pangu Technology headquarters, Xiao Ming still brought Xu Limin and told him about superstrings and gravitational waves.

Xu Limin was stunned for a long time, knowing that Xiao Ming was not joking.

"The detailed information is on the supercomputer at headquarters. This is a long-term project, but it will require a great deal of effort from you."
