The entire controllable fusion battery project was split into 13 sub-projects, covering all components from laser ignition devices to generator sets, with a total of six scientific research institutions participating in the research.

With the successful case of the Pangu fusion reactor in front, Lu Zhou is still quite confident in this project.

However, there are still differences in the discussion about nuclear fuel for fusion batteries.

Dumbfounded by the crazy plan described by Lu Zhou, he opened his mouth in surprise, and after a long while, he spoke in an unbelievable tone.

"Are you sure you want to use helium-three as fuel? The reaction cross-section of helium-3 and deuterium is only one-tenth of that of DT reaction, and it will be dozens of times more difficult to ignite it than igniting DT mixed fuel! ”

He is not the only one who holds this view, Academician Wang Zengguang, chief engineer of the Nuclear Industry Group, also nodded.

"I also think that it may be impractical to go directly to helium-3, although according to what you said, it saves the space and cost of the core, but in fact this part of the cost is just passed on to other components such as laser ignition or microwave ignition device."

Academician Yu Jiannan, who is not very familiar with Lu Zhou, did not directly oppose it, but only vaguely expressed his opinion.

"It's not necessarily a good thing to take too big a step."

The index finger tapped lightly on the table, and Lu Zhou thought for a long time.

It's a matter of trade-offs.

If the DT mixture is selected as the fuel, then the reactor core will have to be loaded with a liquid lithium neutron recovery system, and the volumetric energy density of the entire fusion battery will be reduced. If He-3/D is selected as the reactant, at least 15% of the core volume can be saved, and the volumetric energy density of the entire battery pack will be increased.

However, Academician Wang's words did speak to his heart, with the current laser ignition technology in China, rashly choosing this radical technical route may not be able to achieve the effect he expected.

The silence lasted for about five minutes, and Lu Zhou had an idea in his heart and spoke.

"Then let's make a compromise."

Sheng Xianfu: "A compromise? ”

Lu Zhou nodded: "Just like the ignition device, we will go through two technical routes." One is a fusion battery for DT fuel, and one is for He-3/D fuel. In terms of interface size, we can agree on a unified standard, and if the technical bottleneck of fusion battery technology of He-3/D fuel cannot be solved, we can also use DT fuel immediately. When the problem of helium fusion technology is solved one day, even if the technology is upgraded in the future, it will be easier to upgrade the equipment. ”

Academician Wang Zengguang thought for a while, nodded and said, "I think it's okay." ”

Academician Yu Jiannan still said very little, just nodded and said: "As long as the budget is okay, I have no opinion." ”

glanced at the other people, and seeing that there were no more opinions to put forward, Lu Zhou clapped his hand and said, "Okay, this matter is settled." ”

Directly on helium three, it is indeed too advanced.

The persuasion of a few old "teammates" also made Lu Zhou sober up.

He admits that when he excavated the technical route of controlled fusion miniaturization from the wreckage of that advanced civilization, he did swell a little to the point of ignoring the industrial level of Earth's civilization.

In fact, it is not easy to make fusion energy batteries.

As for completely restoring the technology on that engine, I am afraid that it may not be possible even by the end of the century, let alone now......

After leaving the conference room, Lu Zhou originally planned to go back to the underground laboratory to continue thinking about the Hall propulsion unit, but he thought that there was still one thing to deal with, so he returned to his office.

Some time ago, while approving the project, the senior management suggested that he submit the paper on the feasibility of fusion battery technology to relevant academic journals.

Although he guessed what the higher-ups were thinking, Lu Zhou didn't have any opinions.

What is written in the paper is his academic opinion.

If the senior management has no problem with the content of the public paper, he will naturally not object to the paper being submitted.

After taking out the paper he wrote some time ago and flipping through it, and deleting the potentially enlightening content in it, Lu Zhou only retained a few vague concepts such as "detachable core", "laser heating", and "microwave heating", and then translated them into English.

In fact, it doesn't matter if you submit the paper directly without deletion and modification, after all, this kind of paper with a strong subjective color will not involve specific research ideas and experimental plans, but only a discussion of "feasible" or "not feasible".

As for whether to do it or not, everyone still has to rely on their own abilities.

After reading the deleted paper from beginning to end, Lu Zhou, who stared at the PDF file on the screen, fell into thought.

Which journal is better?

After thinking for a while, a smile appeared on the corner of his mouth, and he suddenly had an idea in his heart.

Digging through a list of mailboxes that he hadn't used for a year, he found the email address of the PRL editor, and he thought about the wording and attached the manuscript to the mail and sent it.

When he clicked send, Lu Zhou's expression couldn't help but be a little playful.

I wonder if after reading this paper, will anyone praise their internationalist spirit?

In addition to the peers who study controlled fusion, I think they probably will......

……

While completing the submission to PRL, Lu Zhou hung the paper on Arxiv, and then didn't bother with it.

But what he didn't know was that almost the afternoon of the day after his paper was posted on Arxiv, his paper was integrated into his PPT.

Los Angeles International Hotel.

Hundreds of square meters of meeting rooms.

When Mr. Benderbauer, president of Triple Alpha, announced that the company's next plan was to build a plasma engine with a fusion battery for the U.S. moon landing program, there was an uproar in the audience.

Although the investors sitting here may not understand what controlled nuclear fusion is, that doesn't mean they are stupid.

It has only been less than three months since the Pangu demonstration pile was ignited, and here on the other side of the Pacific Ocean, I haven't even seen the shadow of controlled fusion.

Quite a few people even began to look at their watches, as if they had already made up their minds, and if they didn't hear anything of value after another five minutes, they were going to get up and leave.

However, in the face of such a situation, Bendbauer did not panic in the slightest.

I saw that he was wearing a plaid T-shirt, dressed very Silicon Valley, he cleared his throat, faced the investors at the scene, and continued in a subdued voice.

"Miniaturization of controlled fusion!"

"I know it may sound incredible, but it's not as unattainable as we think."

Soon, the PPT turned to the next page.

What appears on the screen is a paper hanging on Arxiv.

As for the author of the paper, it is Lu Zhou, the chief designer of the controllable fusion project, who is in the limelight.

Seeing this paper, the audience was in an uproar again, and the sound of discussion spread from the middle to the surroundings.

Even those who were originally dismissive of this press conference couldn't help but look at the PPT twice.

After all, this is Lu Zhou, recognized as the father of controlled fusion!

Others say that controlled fusion miniaturization may be regarded as a fart by them, but the meaning of what this big bull said is completely different.

At this moment, sitting in the corner of the back row of the venue, ExxonMobil CEO Woods is staring at the name on the screen with a complicated expression.

To be honest, he is not optimistic about Tri-alpha, a pompous Silicon Valley company, and he prefers to invest in the down-to-earth and long-established General Atomics company.

However, when he saw the name, the thought in his heart was shaken.

It can't be helped, just because the name left a deep impression on him.

Now the size of the lithium battery market has increased more than 100 times, and seeing that this cake is getting bigger and bigger, the entire Wall Street is beating its chest.

From the anode material of lithium battery to the cathode material of lithium-sulfur battery, this cake with cream originally belonged to them, but they can only watch others lie down and make a fortune after spending a lot of money in the field of new energy.

Now that nuclear power technology has made breakthroughs, the cost of power generation has been further reduced, and the scale of the lithium battery market will only get bigger and bigger.

It is precisely because he once missed such a big piece of cake that he can't ignore the paper on the technical feasibility of the paper completed by Lu Zhou.

On the other side, Bendbauer, who was standing on the stage, took Lu Zhou's paper and continued to talk eloquently.

“…… It's a detachable structure that allows us to make the reactor core something like a battery, which allows us to ignore the damage to the structure of the material from radiation to a limited extent. ”

"Based on this design, this one-time controllable fusion battery is much less difficult to engineer than a fusion reactor! While its cost is an issue, it's nothing compared to the amount of money we spend on spaceflight. ”

Seeing that the eyes of the investors in the audience had gradually changed from suspicion to fire, Bendbauer knew that the time was almost up, so he threw out the last bait and said with a bright smile.

"As for whether our products can find a market, you don't need to worry at all."

"In fact, just yesterday, we entered into a strategic cooperation agreement with Space-X to develop fusion batteries that can be used in spacecraft. Miniaturized controlled fusion devices will be prioritized for use in the aerospace field, and related issues have been reviewed on the desk of the Diet Budget Committee! ”

"I believe that it will not be long before our rockets will be able to use clean and endless nuclear energy, and our footprint will be all over space. I can even assert that this day will be faster than the National Controlled Fusion Facility in California! ”

That agitated. The emotional voice seemed to ignite the emotions of the entire venue.

Glancing at the secretary next to him, Woods lowered his voice and said.

"I need a briefing on Tri-alpha's earnings and business operations!"

The secretary's heart moved slightly, and he immediately understood what the CEO was thinking.

"Yes sir, what you want will be on your desk tonight."

Woods grimaced and said, "Go now, I'll see it before the dinner at six o'clock." ”

Hearing this strong man's difficult request, the secretary nodded stubbornly.

"Yes."
