Two days later, Chen Nian returned to Chengdu.

The foundation of the superconducting industry and the fusion industry has been basically established, and the next thing to be developed is a series of downstream industries and derivative technologies.

For this, Chen Nian is not in a hurry.

In fact, even with such a mature technology accumulation and strong mobilization capacity as Huaxia, it is impossible to achieve the full rollout of these two new technologies in a short period of time.

His own psychological expectation is 10 years.

Within 10 years, the comprehensive substitution of most technical fields will be realized, and the penetration rate and coverage rate of primary results will reach 100%.

On this basis, the transformation of the entire social form will be completed within 20 years, and at that time, the whole of China will truly enter the fast lane.

Sitting in his office, Chen Nian breathed a sigh of relief.

Sure enough, I don't know when I started, and I have become accustomed to living in this city.

Although his trajectory is office, home, and laboratory all year round, as soon as he returns here, he has a sense of security that he is "protected".

This feeling certainly has nothing to do with "protection" in the true sense of the word, but rather a kind of psychological comfort zone.

It seems that it's time to bring your parents over as well? ——

Forget it.

The last time they called, they were still urging marriage, and living together may be more troublesome.

The revolution has not yet succeeded, how can we talk about children's affection?

Thinking of this, he sat up straight again, and said to Chen Guo on the sofa:

"Professor Chen, you can help arrange Qiao Mai's affairs, she plans to go to Qatar, and if necessary, give her some convenience."

"Don't worry, it's already arranged."

Chen Guo nodded and replied.

In fact, in his heart, Qiao Mai is a good direction to solve Chen Nian's "personal problems", but through several temptations, he also determined that Chen Nian does not have this idea for the time being, so even if it is mentioned in the conversation, he will not extend the topic without interest.

"That's fine. Qiao Mai is still relatively talented in the field of hydraulics, and I estimate that in another ten years, she may become a technical leader in the field. ”

"When she is young, you have to let her exercise more, and the resources she is given must also be given."

Hearing Chen Nian's words, Chen Guo couldn't help laughing.

"What you're saying is old-fashioned!"

"Seriously, when you met at AH, you wouldn't talk to her like that, would you?"

"Not really."

Chen Nian hurriedly waved his hand.

Although many people always like to describe the top students, scientific researchers, science and engineering geniuses, etc., as some kind of "high IQ, low emotional intelligence" image, but in fact, this is not the case at all.

What is emotional intelligence?

In fact, it is nothing more than the degree of understanding of the logic of "human feelings", which itself is also traceable and theoretically supported.

Would a person with a high IQ not understand such a thing?

At least Chen Nian himself can understand.

Therefore, even if he didn't have the experience of his previous life, it was impossible for him to do something to put on an official show in front of others.

"That's good, after all, you are friends first, then comrades, and there is no need to be too rusty in the relationship."

"I know-—— don't talk about this, I received a message on the way back, saying that Lao Mei is ready to restart the lunar exploration program?"

Chen Guo immediately nodded and replied:

"Yes, the gossip that has just been released, the official plan has not been officially announced."

"But there is a high probability that this time they are playing for real, and their goal is very clear, that is, to go for helium 3."

Chen Nian's brows furrowed slightly.

The idea of replacing deuterium with helium-3 as a fusion reactant is not a bizarre idea in itself, in fact, after the birth of fusion theory, it was widely accepted that helium-3 was a more suitable reactant than deuterium.

The reason is simple, the fusion reaction between helium-3 and helium-3 is a more efficient fusion process, and the energy released by the reaction is much higher than that of deuterium-deuterium fusion.

At the same time, helium-3 fusion produces a low number of neutrons and low relative energy losses, which is a great advantage for controlling radiation losses and material damage in reactors.

There is only one reason why it has not become a mainstream research direction:

The stock of this thing on Earth is too low, but it is abundant on the Moon.

In today's technological environment, it is difficult for humans to maintain the operation of a near-Earth space station, let alone the commercial transportation of the moon landing.

Of course, for Huaxia, this is an inevitable step.

In the future, whether it is the use of space elevators or the use of large-scale air platforms as a springboard for multi-stage launches, it is a feasible solution.

Can it be beautiful??

In the absence of room temperature superconducting materials, they want to carry out a large-scale moon landing, which seems to be a bit too foolish.

"Do you think they can do it?"

Chen Nian asked.

"It's hard to say, after all, they have done it decades ago, and now whether it is in the field of aerospace, electronics or machinery, technology has been greatly improved, and if they want to replicate it again, I'm afraid it won't be too difficult."

"The only problem is that the moon landing is a very proprietary technology-—— or we call it a specific technology."

"The specific technology itself is very easy to be lost, and their complete system for manned lunar landing did not meet the standard of 'mass production' at all."

"Not to mention that more than 40 years have passed now, even in the 80s of the last century, when all their technicians were still alive, in fact, the moon landing technology has reached the verge of being lost."

"If they want to do it again now, in a word: there is no homework to copy, start all over again."

Chen Guo finished his judgment, and Chen Nian on the other side also nodded in agreement.

"Same as I thought."

"Going to the moon with a cannon and going to the moon with a rocket, the technical path is still different after all."

"But then again, what was the result of their moon landing?"

"We believe they have achieved good results."

Chen Guo replied ambiguously.

"Okay."

Chen Nian didn't continue to ask, but he clearly remembered that in his previous life, the Yutu-1 lunar exploration rover designed according to Lao Mei standards had suffered a lot on the surface of the moon.

It was not until the domestic technology was replaced that Yutu No. 2 could be regarded as going smoothly.

At least from this point of view, it is not appropriate to copy their experience.

"In any case, their decision to launch their own moon landing program means that our plan to exchange a part of nuclear fusion technology for the other party's full set of space industry achievements has gone bankrupt, right?"

"They only have so much chips left in their hands, and they plan to gamble to the end, and they really show their national character to the fullest."

Chen Guo shook his head a little amusedly and replied:

"It's not that exaggerated. At their current level, a moon landing and return would take two to three years at most. ”

"Instead of gambling, they're quite cautious."

"After all, in two to three years, our space industry will not be able to reach their level, and if they fail then, there will be room for repentance."

"Nope."

Chen Nian interrupted Chen Guo's words.

"In two to three years, it is indeed impossible for us to achieve a comprehensive surpass in aerospace technology, but it is not difficult to come up with one or two typical projects."

"After all, it's not that hard to be last moon."

After sending Chen Guo away, Chen Nian did not leave the office immediately, but followed the topic just now, and immediately began to sort out the technology needed for the lunar exploration program.

Actually, he said that "there was nothing difficult about the moon last month" is really not bragging, not to mention that there is a big killer weapon of the system now, even if there is no one?

In the last life, Huaxia launched the Chang'e-1 lunar exploration satellite for the first time in 2007, and then launched Chang'e-2 and Chang'e-3 in just six years, and successfully achieved the first soft landing on the moon.

That was 2013, and only 6 years had passed since the launch of the first lunar exploration satellite!

In this life, the progress of the Huaxia lunar exploration project is faster than the previous one, the launch time of Chang'e-2 has been advanced to the end of 2009, and the main construction and preparation of the Chang'e-3 project has been completed more than half.

If it goes well, by the end of this year and the first half of 2013, the moon landing will be realized.

So, in this case, "going to the moon" can't be considered a problem at all.

The question is how to go up to the moon and bring back enough samples to prepare for subsequent large-scale mining.

In this process, the core actually consists of two parts:

The first is the question of what kind of technology should be used to send heavy exploration and mining equipment to the moon and ensure its smooth return.

The second is the issue of cost, in what form of equipment, as far as possible to reduce the cost of monthly round-trip.

For the former question, Chen Nian actually didn't plan to spend too much time and energy.

After all, it is a miracle that metallic hydrogen is not only a superconductor, but also an extremely terrifying energetic material.

Coupled with the previous technology accumulation of TBCC engines, new engines + new fuels, it is not too much of a problem to send a small excavator up.

Again, the key lies in the cost part.

The purpose of going to the moon is to dig helium-3, and the purpose of digging helium-3 is to improve the efficiency of fusion reactors.

And if the costs of extraction outweigh the benefits of efficiency gains, the gains outweigh the losses.

Chen Nian knocked lightly on the table, thinking about the possible technical routes.

According to his experience, there are only a few technologies that can be achieved in a short period of time to reduce the cost of space flight on a large scale, mainly rocket recovery, space shuttles, high-altitude assisted launches, magnetic catapults, and high-altitude vehicle capture.

Among them, rocket recovery was the most mature in the previous life, and it was also the most in line with the existing technical route, and there was no doubt that Chen Nian put it on the highest priority.

In terms of the space shuttle, after having rocket recovery technology, it should be said that it is relatively frivolous, but it happened that TBCC technology was pointed out in advance in Huaxia, which led to the prospect of the space shuttle suddenly becoming broader.

As for the high-altitude auxiliary launch, the original route of this thing was to use a high-altitude balloon to assist the launch, and the stability was ridiculously poor, and it should have been the first to be eliminated, but it was so coincidental that Huaxia was engaged in an aerial platform project, which made it the technology with the largest imagination space.

This was followed by magnetic ejection, which was given room for realization by superconductor + electromagnetic orbital technology.

High-altitude aircraft capture -—— large transport aircraft, TBCC engines have laid the technical foundation.

Looking at it in a circle, every direction is a good direction!

Chen Nian couldn't help but hold his forehead.

It's okay not to tidy it up, but after sorting it out, he found that in less than 10 years, the foundation laid by Huaxia is really stronger than he imagined.

Choice phobia is committed, who knows?

I'm afraid Lao Mei doesn't have this kind of trouble at all.

After hesitating for a long time, Chen Nian did not finally finalize the next direction, and what is even more nonsense is that the core equipment corresponding to these directions has the same number of source points required for analysis in the system, all of which fluctuate around 500 points.

There's no choice.

He sighed, leaned back in his chair, and thought to himself:

It's better to get a space shuttle, and you can also start the space route in advance, and you can go to space to see it in the future

But I still want to engage in high-altitude assisted launches.

Big is good, and the floating island is a man's romance, okay?

Can the Nantianmen project be faster?

Just as he was silently entangled in his heart, there was a sudden knock on the office door, and then, Li Xiang pushed the door and walked in.

Seeing his sad face, Li Xiang asked curiously:

"What's the problem?"

Chen Nian shook his head and replied:

"It's not a problem, there are too many choices to choose."

He gave Li Xiang a rough idea of his considerations, and the latter couldn't laugh or cry.

"You're really cheap enough and you're selling well. But seriously, since other technical routes have already been accumulated, why don't you just open a new route? ”

"New route?"

"That's right, if you do something else, the technology doesn't overlap, maybe it can also drive the development of other directions."

Hearing Li Xiang's words, Chen Nian also came back to his senses.

Indeed, a good idea.

But the question is, what are you doing?!

"Then what are you talking about?"

Chen Nian looked at Li Xiang with blazing eyes.

He is not afraid that the other party will come up with wild ideas, but he is afraid that he has no imagination.

Li Xiang pondered for a moment before speaking:

"Actually, I've been wondering why the initial velocity of the rocket launch must be so high."

"According to the intuitive feeling, as long as the downward thrust is greater than the gravity, I can fly into space with a drone hanging myself, right?"

"That's right."

Chen Nian nodded and replied:

"Theoretically, as long as you have enough thrust, you can climb to the moon even at the speed of an ant."

"The reason why you want high speed is because you have to break through the first cosmic speed - you can think of a rocket as a cannonball, and you can just hit it and forget about that, which is very understandable."

"However, the current rocket launch is not a one-shot deal, and it has to go through multi-stage acceleration in the middle, huh?"

Chen Nian's eyes lit up, and he suddenly understood Li Xiang's thoughts.

And Li Xiang also took the opportunity to answer:

"So if you change this acceleration process to a constant speed. Is it also feasible? ”

"Isn't Cheng Fei already ready to engage in the electric aviation development project? Will this thing work? ”

Chen Nianmeng nodded and replied:

"There's a head!"

At this time, a picture that he had never imagined before appeared in his mind:

A vehicle carrying solar panels and metallic hydrogen batteries slowly lifts off the rooftops of residential buildings, then slowly climbs into space at a speed of one meter per second, igniting small fireworks rockets after entering outer space, sending itself into space

This picture could be further optimized.

After helium-3 is collected on a large scale, it will no longer be difficult to miniaturize fusion reactors.

If we can make a work-free engine, it will really be a new era.
