Chapter 604: Inescapable bottleneck

It's across the Pacific at noon.
After sending the email, Salot went to the bar and got drunk.
In order to maintain a clear head in the experiment, he never had the habit of drinking at noon, but this time it was an exception.
Sitting next to him in a bar on the edge of Silicon Valley, his assistant Paul looked at him with a sigh and comforted him.
"It's not necessarily a bad thing to sell your laboratory to ExxonMobil. Although Professor Lu is an excellent ... or a great scholar, the resources he can give you are not Many. Except that Exxon Mobil paid us 50 million to buy us, certainly not just to support us on the cold bench ... "
Seeing Professor Sarrot had no response at all, Paul knew that most of his comfort did not work, so he shrugged and forcibly ended the topic.
"In short, being rich is not a bad thing."
Sarrot grinned.
"You do not understand."
Paul: "... I don't understand anything?"
Sarrot didn't explain anything, just raised the bottle and sipped it a few sips, but talked about other things by himself.
"My dear Paul, I have always thought that academics should be a free thing. As long as it is not against the most basic morality of human relations, even if it is not so correct, you should claim it as long as you believe it is right . The more people don't believe you, the more you should prove to them that you are right. "
Paul frowned and asked, "Isn't it free now?"
"Perhaps," Rarot sighed, looking up at the ceiling, "but when you reach my level, when your research or behavior has become a gear to move the world forward ... You may feel differently about freedom. "
Paul didn't say anything, just looked at Professor Salot in puzzlement.
Without talking for a while, Sarrot put the empty bottle next to the stool and picked up another bottle.
Just as Paul was going to remind him "you've drunk too much", he said abruptly.
"After a while, I plan to emigrate."
"Where? Professor Lu's lab?"
"I don't know. It's not Hua Guo anyway, there is only one Professor Lu ..."
With a bottle of wine in mind, Sarote thought for a while, scratching his hair decadently, "Maybe the Netherlands? Hear my father said that our ancestor lived in a small town in Utrecht Province until the German bombed Rotterdam ... but I have never been there. A long time ago, Utrecht University sent me an invitation letter asking me to be a professor there, but their salary is too low and the resources are not as good as Cornell University gave me. ... but now I think, if I accepted that invitation, maybe it wouldn't be so bad? "
...
The research on fusion batteries has fallen into a bottleneck. The problem of core heat dissipation seems to be a difficult problem to solve, so that many people within the project team have started to doubt the technical route itself.
After all, can nuclear fusion really be miniaturized like nuclear fission?
Is this route of inertial restraint really feasible for miniaturized, controlled fusion?
The most disturbing thing is, if you don't use a magnetic field to withstand the energy that surpasses the star, what kind of material can you withstand the instant heat?
However, apart from inertial constraints, they also seem to have no more choices. After all, on a small spacecraft, there is simply not enough space to make them a closed magnetic cage sufficient to constrain those plasmas.
No one can answer these questions, and no previous research can be used as a reference.
In order to find inspiration for solving the problem, these days Lu Zhou has collected a large number of papers related to aerospace, fission battery, and space station heat dissipation technology, trying to get inspiration from some public research materials.
In fact, these papers did give him some inspiration.
For example, a paper on "First-principles study of phonons in α-boron and its icosahedron boron-rich compounds" provides an interesting thermoelectric conversion model while discussing the phenomenon of electrons scattering phonons. .
Converting thermal energy into electrical energy is indeed an interesting idea in a sense. In fact, most nuclear fission batteries used in spacecraft are based on this method of generating electricity.
However, this does not solve the problem fundamentally.
Using the temperature difference between the spacecraft and the spacecraft to generate electricity may improve the efficiency of converting thermal energy into electrical energy to a limited extent, but it cannot change the fact that it is difficult to remove heat.
Sitting in the office, Lu Zhou, leaning on an office chair, turned his pen and muttered to the ceiling.
"It would be nice if the controlled fusion reaction could slowly exotherm."
Or, let the area where the pulses fire is small enough ...
At this time, the sound coming from the side interrupted his thoughts.
"Professor, what are you talking about?"
Holding a paper bag in his chest, Zhao Huan, standing at his desk, was looking at him with curiosity.
Lu Zhou: "Nothing ... is there anything?"
Zhao Huan nodded and said, "Well, it's the tenth week right away. Your calculation materials class is about to start. This is your schedule."
"I know, the timetable is here," said Lu Zhou, rising from the office chair, sighing, "... I'll go out and call me if something happens."
"Um." Zhao Huan nodded.
I don't know if it is an illusion. She always feels that the professor's mood is not so good.
In fact, Assistant Zhao's intuition was not wrong. Lu Zhou's mood is really not so good now, and it can even be said to be a little irritable.
Intuition told him that the research idea he chose was correct.
Yet it seemed as if an invisible barrier existed, blocking the seemingly feasible road before him.
Vaguely, Lu Zhou felt that the bottleneck did not lie in the field of engineering, but in the field of theory.
That is, there is no sufficient theoretical basis to support his research on the miniaturization of controlled fusion.
Moreover, this difficulty is not as good as a stellar to Tokamak, from the engineering point of view to bypass magnetic islands, magnetic surface tearing and other phenomena in plasma physics, to transfer theoretical difficulties to engineering difficulty And cost.
"Is research efficiency penalties caused by advanced research?"
Walking on the tree-lined path of the campus, thinking of the Luzhou here, he suddenly shook his head with a smile.
About the year before last, he had encountered a similar situation when he was new to research on controlled nuclear fusion.
At that time, the method of research on L-manifolds and partial differential equations was not put forward. The existence and smoothness of the solution of the NS equation and the theoretical model of plasma turbulence belong to the two unsolved mathematical and physics circles mystery of.
It is also after these theoretical problems have been solved that the realization of controlled fusion technology has a sufficient theoretical basis.
Without these theories ~ EbookFREE.me ~ Whether it is the German Spiral 7-X or the STAR-1 stellar device modified by him, it is almost impossible to achieve those proud results.
However, what exactly is the theoretical bottleneck for miniaturization of controlled fusion?
If this bottleneck is really theoretical ...
After crossing the tree-lined path, thinking about the problem of Lu Zhou, he unknowingly went to the place where he usually lectures.
On the podium, standing on a professor he didn't know, probably listening to physics.
Through the glass by the wall, he can clearly see that the students in the classroom are listening attentively.
However, as he was about to leave here, the light glanced from the corner of his eyes on the blackboard suddenly caught sight of a few key words.
The inspiration flashed through.
Lu Zhou's heart moved slightly, without any hesitation, walking towards the back door of the classroom.
