Chapter 1506 Do You Dare to Answer?

"cough--"

On the lunar rover, upon hearing the soft cough from the communication channel, the man sitting next to him looked towards Lu Zhou and asked with concern.

"What's wrong?"

"Nothing, just a little itchy nose..."

Through the mask of the spacesuit, Lu Zhou, who couldn't touch his nose, sniffed awkwardly. It feels really uncomfortable to want to sneeze but not be able to.

I don't know who is thinking about me.

Putting this matter aside for the time being, Lu Zhou cast his gaze out of the car window and looked at the city not far away, leaning on the edge of the crater mountain, and couldn't help feeling a little bit emotional in his heart.

"I designed that blueprint, but I didn't expect that a hundred years later, this place will be so prosperous."

The man sitting next to him smiled and said.

"It seems that everything you expected has come true."

Lu Zhou nodded.

"Well, at least half of it has been realized."

At this moment, the man sitting next to him in his early thirties is named Ye He, and he is the mayor of Guanghan City. After hearing that East Asia Power's investigation team for selecting a site for the second-generation controllable fusion reactor was led by himself, Mayor Ye personally received his group.

After hearing Lu Zhou's words, Ye He smiled jokingly and said, "Can I ask what the remaining half is? I also ask Academician Lu for advice."

Lu Zhou: "Energy."

The moment Ye He heard these two words, Ye He was slightly taken aback, with a trace of obvious surprise floating in his eyes.

Although this is not a secret, for a scholar who just woke up from the dormant cabin last month and came from the era of a hundred years ago, he actually pointed out the biggest bottleneck facing the development of Guanghan City in one sentence, It is inevitable that people will be a little surprised.

"You see it?"

Lu Zhou smiled lightly and said.

"That's right."

Strictly speaking, the moon is not suitable for the development of densely populated cities. The single resource and high maintenance costs severely limit the threshold for industrial development here.

Unlike the earth, compared with the earth where controllable fusion technology has blossomed everywhere, the energy cost of the Guanghan Special Economic Zone that still uses solar energy can be said to be quite high.

It's not that people here don't want to popularize controllable fusion technology, but because it's too difficult to build a nuclear fusion reactor on the moon.

One of the most troublesome problems is the problem of heat accumulation in the vacuum. According to a rough estimate, the heat dissipation plates needed to build a first-generation fusion reactor can almost cover a small half of the moon.

Lu Zhou reckoned that without the support of the second-generation controllable fusion technology, Guanghan City would be able to develop to its current scale, which is basically the end.

This place is different from the earth. The entire artificial ecosystem and life support facilities are completely maintained by energy. In other words, people have been consuming precious energy from the moment they set foot on the moon.

There were not many people in Guanghan City in the early days, and it was only the size of a scientific research station. A solar array the size of a crater and an energy storage facility the size of a scientific research base could fully meet the needs of the entire colony for a day and night cycle.

However, now, the entire Guanghan City has a permanent population of 100,000 at least. As the tourism business research center of the Earth-Moon system, the floating population here has jumped tenfold.

Not to mention the astronomical amount of energy consumed every day, most of this energy gap has to be filled by solar energy facilities, so that the urban planning of the entire Guanghan City is designed very compactly. Reached the pinnacle of minimalist architectural style.

And this is why most countries simply skipped the moon and set the pace of colonization directly to Mars.

There has been no hope for the second-generation controllable fusion. Whether the helium-3 buried in the lunar soil can be used as a strategic material in the space age has been questioned. If it is only for titanium ore and rare earth resources, the asteroid belt can fully satisfy For the supply of Mars and the earth-moon system, there is really no need to gnaw at the hard bone of the moon.

After arriving at the destination, the group got out of the car.

Looking at the crater in front of him, Lu Zhou nodded with satisfaction.

The terrain is perfect, and the angle facing the earth is not bad. Next is the geological composition analysis. As long as the geological structure of the lunar soil below is not loose and porous, it is not a big problem to choose the location of the experimental pile here.

"The conditions here are quite suitable. If there is no problem with you, I plan to build the second-generation controllable fusion experimental reactor here."

"To be honest, according to the blueprint I designed back then, without the second-generation controllable fusion technology, the 100,000 resident population is almost the limit of Guanghan City. The reason why I circled so many helium-three mines at the beginning was to consider Got to this point."

"The result was beyond my expectation. I thought that these good things would definitely benefit my compatriots a hundred years later, but I didn't expect that you didn't even have a mouthful of broth."

Hearing Lu Zhou's ridicule, Ye He looked a little embarrassed, and said with a light cough.

"This...whether the second-generation controllable fusion technology can solve it is not up to me. And I have a confusion here, and I don't know if it is appropriate to ask."

Lu Zhou said with a smile: "If you don't understand, just ask, how can this be suitable or not?"

Mayor Ye said seriously: "The first-generation controllable fusion has the problem of heat accumulation. Doesn't the second-generation controllable fusion have similar problems? I don't quite understand why you choose to build the fusion power station on the moon. Since If there is a means of long-distance power transmission...why not build a power station on the earth, and then send the power directly here?"

Lu Zhou: "Heat accumulation is indeed a problem, but it can be solved for the second-generation controllable fusion. Let's put it this way, because the first-generation controllable fusion will produce extra neutrons, so the design idea of ​​the reactor shell is to recycle the extra neutrons. neutrons, such as liquid lithium neutron recovery technology, etc. Although these designs can effectively recover neutrons, they do not solve the problem of core overheating well, and occupy at least 70% of the design space.”

"...In other words, because the second-generation controllable fusion will not produce additional neutrons, you can omit a lot of cumbersome designs and leave more design space for solving the heat accumulation problem?" Touched thoughtfully With his chin down, Ye He nodded half-understanding, "I seem to understand what you mean."

Lu Zhou nodded approvingly.

"Your understanding is very high—"

"Oh, don't be fooled by his nonsense!"

At this moment, a discordant voice suddenly came from the communication channel.

After hearing this sentence, the group subconsciously looked behind them, only to see an old man in a space suit striding towards this side.

Behind him, there was a young man chasing after the old man with a wry smile on his face.

He recognized the identity of the young man as his secretary, but he didn't recognize who the old man in front of him was. Mayor Ye frowned slightly, but he still spoke with grace.

"Excuse me, old man, are you?"

The old man glanced at Lu Zhou with a bad expression, then looked at Ye He, and said displeasedly.

"Qiu Mingrui! You guys invited me here, don't you know who I am?"

Hearing the old man's name, Mayor Ye's face suddenly showed a hint of bewilderment, and then he smiled and said.

"So it's Academician Qiu, I'm sorry. But, why are you here today?"

Qiu Mingrui said with a smile.

"If I come later, you won't be limped by this guy."

It's okay to flicker...

Do people in the 22nd century know this old meme?

Looking at the old man who was inexplicably hostile to him, Lu Zhou asked curiously.

"Who is this?"

"This is academician Qiu Mingrui, an expert from the Institute of Nuclear Physics of the Pan-Asian Academy of Engineering!" Mayor Ye said with a smile, "We invited the elderly to do the feasibility assessment of the project. After all, you have such a large piece of land. And there are certain security risks, which are normal procedures."

"It should be," Lu Zhou nodded, then looked at the academician Qiu with a bad look, and after thinking for a few seconds, he said, "It seems that you came here to stop me. If that's the case, Just get straight to the point."

I don't know where the anger came from, or if I was just a bad tempered person.

After hearing this sentence, the old man in the space suit stared at Lu Zhou, and put down the words aggressively.

"Don't talk about what you have, I will ask you three questions, do you dare to answer them?"
