"If you want to become an interstellar civilization, the core is the breakthrough of energy technology, high-speed engine, biological life is these three aspects, among which energy technology is the most important, only if energy technology breaks through, can there be enough resources to study the remaining technology."

"The current problems of controllable nuclear fusion can be summarized as the unpredictability of plasma turbulence, the temperature is not high enough, and the magnetic field is not strong enough.

The current technology of mankind is enough to create an environment with hundreds of millions of temperatures, but it is difficult to accommodate such a temperature environment.

This has exceeded the tolerance limit of any one material, and can only be bound by magnetic fields, so from an engineering point of view, a more powerful magnetic field is needed to bind the plasma.

A larger magnetic field requires a larger current, and the heating phenomenon of the conductor through the current must be completed by using superconducting materials, and if there can be superconducting materials at room temperature, then these two problems are no longer a problem.

In addition to these three problems, there are also the inaccurate control of the magnetic field, the tearing of the magnetic surface, and the interference between the magnetic field and the plasma, but these problems are actually caused by the lack of understanding of plasma turbulence, resulting in the design of the device is not optimized enough. ”

"The technical obstacles currently encountered in the final controllable nuclear fusion are actually caused by the unpredictability of plasma turbulence and the delay in breaking through the technology of superconducting materials at room temperature."

Lin Meng's retreat research brother guessed, the compression chip programming design was completed, Li Yashan took a long leave to negotiate with ZTE, and Brother Zao was in charge of the registration of global patents.

Lu Yi soaked in the library for more than a month, looked through the materials, looked up the literature, and finally had a clear understanding of the current difficulties encountered in controlled nuclear fusion.

"It's hard, it's so difficult!" Lu Yi closed the book and frowned deeply.

The superconducting phenomenon has been discovered for more than 100 years and studied for decades, but it still needs to be soaked in liquid nitrogen at more than 100 degrees below zero to produce superconductivity.

The plasma turbulence phenomenon, which seems simple and can be analyzed directly from the data level, is not simple.

It is already a fact that high-temperature plasma is not observable with current technology.

We all know that detection is actually the process of sending a beam of light or a particle beam, and then collecting the bounce and collision data of the beam particle beam, and finally analyzing the data.

The temperature is the embodiment of the thermal motion of the molecule, and the plasma of nuclear fusion has tens of millions or even hundreds of millions of temperatures, and 99% of the particles enter such plasma directly and change their properties and eventually lose their effectiveness, or they are washed away by the plasma with extremely violent microscopic movement and cannot complete the final data acquisition.

If it cannot be detected, there is no basic data, and if there is no data, how can we analyze and summarize the phenomenon of plasma turbulence?

"Lin Meng said that the tool key has been found, Li Yashan and ZTE Unicom have also reached a preliminary consensus, and the global patent application on Brother Zao's side has also entered the patent secrecy stage, it seems that I need a plasma expert."

......

"Lu Lu, this is Professor Zhang's office, and I told him about the general situation."

A young and beautiful master's sister in a short skirt took Lu Yi to a professor's office, and after understanding that he needed a plasma expert to help solve some questions, Lu Yi immediately contacted a senior sister who had been accosted before.

With the help of his own handsome network, he found Professor Cheung, who has a deep knowledge of plasma at CUHK.

"The professor is very talkative, but he hates those students who don't have a good attitude, and Lu Lu will remember to be polite and upright later."

Standing outside the office, the senior sister explained some of the professor's personality preferences to Lu Yi in a gentle voice, so as to prevent Lu Yi from annoying the professor by not paying attention.

"Thank you, senior sister, then I'll go in." Lu Yi listened patiently, and he smiled, who was already handsome, and signaled that he was going in.

Under the gentle cheering gaze from behind, Lu Yi knocked on the door, and after hearing the sound of inviting in from inside, he pushed the door and walked in.

"Hello, Professor Zhang."

"Sit."

Professor Zhang, who was in his 50s and still looked ruddy, raised his head from the literature on the table and asked, "Are you the classmate Lu that Linlin's girl said?" ”

It can be heard that the relationship between the senior sister who brought Lu Yi over and the professor is still very good.

"Yes, there are some questions about plasma that students have been unable to understand, and I want to ask you for advice from the professor." Lu Yi nodded and said his purpose simply.

"Then how did you find me?"

Professor Zhang looked Lu Yi up and down, and became a little interested, but this interest flashed with a strong gossip in Lu Yi's eyes.

"I asked them about the situation of CUHK in plasma, and I learned that you are the most experienced expert in this field, so I wanted to ask you for advice."

Lu Yi faintly slapped a sycophant, and God gave him a face with a sycophant effect of +100, and he learned how to use his innate advantage very early.

Sure enough, in the face of Lu Yi's words, Professor Zhang's face became even more soothing, and he showed a smile and smiled: "What is the question, see if I can answer it." ”

"I would like to ask about the unpredictable phenomenon of plasma turbulence, at this stage, the international data on high-temperature plasma are inferential predictions, and the data obtained is not very accurate, I would like to ask if there is a way to improve the observation of plasma?"

"Plasma turbulence? Are you planning to move towards a thermonuclear experimental reactor? ”

Professor Zhang was stunned, at first he thought that Lu Yi did not understand some plasma problems in the magnetic field, because this problem was the hardest hit area of students, and he didn't think that it was this ultimate chaos problem as soon as he opened his mouth.

Lu Yi's major and grade he already knew, and now when he heard the plasma turbulence, Professor Zhang quickly thought of controlled nuclear fusion.

He has seen a lot of such students, and many physics students will be involuntarily attracted by this vast project that represents the future of mankind and the future of civilization, but this project is not something that ordinary people can participate in.

"What was your GPA in your last school year?" Professor Zhang did not answer, but asked Lu Yi's GPA.

“83.5.”

"I don't recommend that you go in the direction of a fusion core."

Professor Zhang shook his head, physics and mathematics are both very tests of talent, and Lu Yi's grade point of 83.5 proves that although his talent is okay, it is only average, and it is difficult to achieve anything in controlled nuclear fusion.

"Professor, you misunderstood."

Lu Yi smiled bitterly: "I didn't plan to study this myself, but I just made a little money and wanted to invest in it, using mathematical models to summarize the fluid data of plasma turbulence to provide data reference for the manufacturing optimization of tokmak and stellarators." ”

"Got a little money and want to invest? How much did you earn? ”

Professor Zhang felt that his head couldn't keep up with Lu Yi's thinking, it was impossible for a junior physics major not to know how much resources it would take to study this, this kid was crazy and thought that there was too much money, right?
