First, low salamander retention and efficient utilization of salamander.
Plutonium has a short half-life and is expensive. Plutonium in fusion reactors needs to be recycled.
Second, resistance to neutron and plasma radiation.
Each deuterium and tritium fusion will generate an energy neutron. These high-energy neutrons can easily break the metal bonds in the first wall material, resulting in a large number of defects, causing radiation swelling, embrittlement, creep and other problems. Resist this radiation;
Third, high temperature and thermal shock resistance.
The working temperature of the first wall of the small-scale fusion reactor is above 1000 ° C, and the instant the plasma bursts can reach 2000 to 3000 ° C. What material can resist this temperature.
Why can these problems be solved on the sun, but not on the ground laboratory?
Because the sun has strong gravitational restraint from the inside, but the ground laboratory does not, it is necessary to restrain high-energy particles with super-strong materials and technologies.
The above three problems are the problems currently facing Pangu Technology.
Even if a device similar to Xia Guochao's Tokemark is made, it can only achieve energy output. It is not cost-effective to measure with economic news.
"Super" here means superconductor.
At a news conference a month ago, Qian Yi only told the media that Pangu Technology had mastered nuclear fusion technology and did not say that it would be commercialized immediately.
This matter was mentioned at the press conference, the significance of deterrence is greater than the actual significance.
To put it plainly, it means a little bragging.
But if the burdock blows out, things won't be done? This is obviously impossible.
Controllable fusion technology is a project that Pangu Technology must win. This is a project that affects the future energy and even the future destiny of mankind.
So when the research was nearing stagnation, Xiao Ming saw an intermediate science and technology catalog about advanced controlled fusion technology.
One of the advanced techniques of controlled nuclear fusion is called gravity creation.
This is too high-end. Under the curiosity, Xiao Ming still exchanged surprise value for the gravity creation in advanced controlled nuclear fusion technology.
Xiao Ming exchanged the surprise value in his hand for gravitational creation technology. This time the exchange used up all the surprise values ​​and also caused the commercial controllable fusion technology to fail to exchange.
But this time the exchange made Xiao Ming feel the true charm of the intermediate technology catalog.
Subverted Xiao Ming's imagination, subverted Xiao Ming's basic knowledge of physics and the universe.
This exchange means that humans have taken a solid step towards the ultimate laws of the universe.
What is gravity?
For a long time, human scientists have listed gravity as one of the four basic forces of the universe.
Gravity, electromagnetic interaction, weak interaction and strong interaction.
But in the long-term exploration, scientists have found a very strange problem, whether in the laws of physics or mathematical models, gravity cannot be unified with the other three forces.
Until Einstein's theory of relativity was put forward, he believed that gravity is not a real force, but a mass object's effect on the bending of the surrounding space.
Everyone knows a typical model. A small ball on the sponge can dent the sponge. And because the sponge is sunken around the ball, and other things are placed, it will tend to fall toward the ball.
This model is analogous to the bending of a large-mass object to the surrounding space-time.
Therefore, Einstein believed that gravity is caused by the geometric bending of space. It can be said that it is not a "force", but a geometric effect of space distortion.
However, when Xiao Ming created a description of gravity in the catalog of science and technology, he was shocked to find that Einstein's law was not completely correct. Gravity could be unified with the other three forces. The description even answered the unified principles of Einstein's relativity and quantum mechanics (Currently, the smooth space-time of general relativity contradicts the dramatic quantum fluctuations of space-time under microcosm).
To make it simpler and clearer, Einstein's conclusion is correct in the three-dimensional space that humans know well, but it is incorrect in higher dimensions.
In the description, the four forces of the universe can even be unified with mass, which involves the basic constituent material of the universe: the superstring.
Everything in the universe, including energy, is made of it, and superstrings are very small, linear "strings." The different vibrations and movements of the strings produce a variety of different basic particles. Energy and matter can be transformed. The frequency of the string's vibration determines the type of particles and their properties.
Gravity can be generated by controlling the properties of superstrings in combination.
After reading the manual, Xiao Ming's head went blank.
This is the real black technology.
The manufacture of gravity can not only complete nuclear fusion technology perfectly, but also 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 nuclear fusion is still better in the traditional way.
Thinking of this, Xiao Ming still casually mentioned ~ EbookFREE.me ~ why can't we create gravity? "
Create gravity?
What a joke!
This can be a bold imagination! But it cannot be achieved.
What level of science and technology do humans have?
Create gravity?
After Xiao Ming said this, Xu Limin and the relevant experts of Xia Guo Energy Lab looked at Xiao Ming.
Xu Limin didn't know if Xiao Ming was kidding.
Xu Limin said: "If you can simulate the star's internal environment and create the gravitational force that constrains high-energy particles, then all the problems will be solved. However, you can only think about it. Create gravitation? How does gravity create?"
Xu Limin used his physical imagination. He said: "Of course we can simulate magnetic fields or use centrifugal force to create so-called gravity, but at the high temperature inside nuclear fusion, everything we do will turn to ashes, and these Gravity cannot compete with the energy of high-energy particles. "
"General Xiao's imagination is very rich! But as Professor Xu just said, there is no way to operate in actual conditions, and the internal temperature is too high. If we can solve the problem that the material can withstand temperature, then it will not be The so-called creative gravity is needed, and it is sufficient to directly use such materials to make the Ultra Tokmak device. "
Everyone just took Xiao Ming's words as a joke and laughed.
Xiao Ming was not angry, and he passed away cheerfully. "Yes, it is imperative to find a way to optimize the Ultra Tokmak device."
But back to Pangu Technology Headquarters, Xiao Ming still brought Xu Limin and informed him about the superstring and gravitational waves.
Xu Limin froze for a long time, knowing that Xiao Ming was not kidding.
"The detailed information is on the supercomputer at the headquarters. This is a long-term plan, but it will require your great efforts."
