"Are you sure there is really a gold mine?"

In Xigong University, Chen Guo said to the phone with a face full of excitement.

The voice on the other end of the phone was extremely calm.

"It is certain that there are, but the reserves and grades are hard to say."

"However, according to the description of the local staff, the Elder-White River area was originally part of the mine lode, and it is normal to have gold mines."

"In addition, this area has never been exploited on a large scale. We judge that the reserves in this area should not be too low."

"Now the strategy has been basically drawn up. We will put forward this condition in the quotation of Gauteng High Speed ​​Rail and strive to win this project."

"If the project can be won, we need the full cooperation of the Civil Affairs Office—or in other words, your Xinghuo team."

"This is our first kick to completely open the door to Africa, and we must kick it beautifully."

"If the Gauteng high-speed rail project can be completed perfectly, then at least half of the infrastructure projects in Africa will be ours!"

"clear!"

Chen Guo replied solemnly.

In fact, he knew from the very beginning that the ultimate goal of the Gauteng high-speed rail project is definitely not as simple as some foreign exchange and a gold mine.

In essence, it is a springboard for China to go to Africa, and it is also our way of "passing on the economic crisis" different from the United States.

We must know that no matter how good a country's resource endowment and technological strength are, the contradiction between resources and development is inherent.

In the early days, most countries can use the resources in their hands to develop their economies at a high speed, but what if one day the resources run out?

In other words, the resources are not used up, but the resource bonus is used up?

At this time, the excess production capacity cannot be exchanged for the relative productivity, and the whole society will be forced to fight for limited resources and pay far more than the unit income should cost.

So, revolution, just like that came into being.

In essence, the ultimate impact of the economic crisis is precisely the revolution.

To solve this problem, it is necessary to find an outward breakthrough for those excess production capacity. Whether it is matching them with more resources or giving them a larger market, it is an effective solution.

——

Africa is such a magical land.

It has both resources and markets.

Moreover, when he exchanges resources for more advanced technology, more advanced infrastructure, and a more developed economic environment, its market will gradually expand.

This creates a virtuous circle.

In such a virtuous circle, a country with sufficient output capacity will continue to develop steadily and at a high speed for more than ten years, or even decades.

That's why, the superiors will attach so much importance to this project.

In fact, what they value is actually this "opportunity" itself.

If we can get the Gauteng project, which is a pioneering infrastructure project in Africa, and make a big publicity for it through the upcoming World Cup, then, as the leader said, it is very likely that more than half of the infrastructure projects on the African continent will Projects are all about us.

And if you can't get

Then it will be much more difficult to find a project with the same function to open up the situation later.

Thinking of this, Chen Guo let out a sigh of relief.

Now, after confirming the existence of the gold mine, the last worries of the superiors have also been dispelled.

Next, it depends on the specific operation of the business port.

However, if they can take down the big African pie, what after that?

The European Raiders should also start operating.

Although they don't need infrastructure assistance, they definitely need products such as communications, machinery, electronics, and energy.

What we need to wait now is just an opportunity like the Gauteng project

On the other hand, Chen Nian has already completed the first week of studying energy materials. During this week, he has almost learned all the basic knowledge related to energy materials, and the efficiency is so high that he himself is afraid.

However, this can only be regarded as swallowing jujube-style learning, and it will take a lot of time to further digest and absorb.

As for the further research content on lithium dendrites, it can only be carried out after he can independently complete most of the preparation experiments of advanced energy materials and fully grasp the principles.

According to his own estimation, this time will take at least 3 months.

It's not short, but compared to other "ordinary people", it's still much faster.

Chen Nian could feel that while the system was imparting knowledge, it had indeed improved his thinking activity to a certain extent.

This allows him to think faster and wider than ordinary people.

With this advantage, he should be able to walk more smoothly on the road of scientific research in the future.

Thinking of this, Chen Nian couldn't help showing a smile.

No one wants to be a slave to the system, and now he is working hard towards "surpassing the system" one day in the future.

Putting down the book in his hand, Chen Nian stood up and moved his hands and feet. At this moment, he noticed the flashing mobile phone on the bedside.

It was his personal one—there was a call.

Chen Nian picked up the phone and looked, the caller was Wang Jiancheng.

He picked up the phone, and before he could speak, he heard Wang Jiancheng's excited voice.

"Senior! The mechanical exoskeleton has been made! Do you want to take a look?"

"WTF?"

Chen Nian was shocked.

This is done?

Isn't this too fast?

——

But it doesn't seem to be fast. After all, what he did this time is a passive mechanical exoskeleton, and the technical difficulty is not high.

After careful calculation, it has been less than half a year since Wang Jiancheng proposed to make a mechanical exoskeleton.

It is not difficult to build an exoskeleton after taking away his usual study and work time.

But to what extent. I really have to go and see for myself!

So, Chen Nian hurriedly continued:

"Where is it? Where can I see it?"

There was faint excitement in his voice.

Obviously, no matter how his rationality tells him "this is just a preliminary attempt", "this thing is not an epoch-making product", "the mechanical exoskeleton is not very effective at present", but in terms of sensibility, no man can refuse mecha.

Even the beggars version is the same.

Hearing Chen Nian's words, Wang Jiancheng immediately replied:

"I rented a single room outside the school as a laboratory. I'll tell you the address, and you can just come here!"

"Come on, I'll wait for you!"

After getting Wang Jiancheng's address, Chen Nian hung up the phone quickly, and then rushed towards the address he gave without stopping.

Fortunately, the laboratory rented by Wang Jiancheng is not far from the school, even if he walks, it is less than 10 minutes away.

Chen Nian arrived quickly, opened the door and took a look, he was immediately stunned by the scene in the room.

The inside is messy, with various parts piled up everywhere, and several small operating tables with different functions are placed on the ground, some are specially used for cutting, some are used for milling, and some are used for grinding.

There are countless other tools, such as angle grinders, electric drills, hand saws, and welding guns. It can be said that they are all available.

He stared and asked in disbelief:

"You saved all this?"

"Yes! I have all the tools. As long as I have enough time, I can make any gadget!"

Wang Jiancheng at the side replied proudly.

Afterwards, he dragged Chen Nian to the depths of this "mechanical forest".

"Come on! Mingguang No. 1 is inside!"

After bypassing a lot of consoles, Chen Nian finally saw the exoskeleton that Wang Jiancheng called "Mingguang No. 1".

Looking at it this way, he found that he was still thinking conservatively.

The standing height of this thing is more than two meters, and the arm span may even exceed two meters.

The entire exoskeleton is painted in pure black, with only a few areas dyed red.

In general, it looks oppressive, but also a little. Nondescript?

Looking at Mingguang No. 1 in front of him, Chen Nian said helplessly:

"You're such a thing. It doesn't look like an exoskeleton, it doesn't look like a mecha, and it doesn't look like a Mingguang armor."

"It's also thanks to you. How did you design this transmission?"

"Pure mechanical transmission!"

While talking, Wang Jiancheng strenuously "climbed" onto the exoskeleton.

As he fastened the various connecting structures, Chen Nian also saw the working method of this mecha.

In general, like the passive mechanical exoskeleton of later generations, the basic design idea of ​​this exoskeleton is also to transmit the force on the arms and legs to the soles of the feet, and use the mechanical structure of the mecha to support the weight of the object. So as to achieve the purpose of saving effort.

However, due to the lack of electronic sensors, as Wang Jiancheng said, the entire exoskeleton is purely mechanical transmission.

It completely depends on the user's own strength to do the initial start. The user not only needs to bear the gravity of the heavy object when lifting the heavy object, but also needs to resist the self-weight of the machine itself.

Where does this save effort?

It is indeed labor-saving to move it up, but the problem is, you have to be able to move it too!

Watching Wang Jiancheng strenuously performing operations such as walking and grasping, a thought flashed through Chen Nian's mind:

Why is this brother so similar to Handmade Geng?

In the end, he really created a bunch of things that didn't exist, right?

But before this thought could turn around, Chen Nian suddenly froze again.

Because he discovered that the fingers of this exoskeleton can flexibly move according to the actions of the operator on the operating handle.

Even each finger can move independently.

That is to say, the transmission mechanism of the entire exoskeleton is designed extremely precisely.

Could this be the legendary "exquisite waste"?

Chen Nian hurriedly stopped Wang Jiancheng's experiment, rescued him from the exoskeleton with great effort, and then said:

"At first glance, this thing is quite handsome, but the practicality is really too bad. From the current point of view, it has no meaning at all!"

"Yes yes! I also don't think this one is practical, so it's just Mingguang 1!"

Wang Jiancheng replied solemnly.

"However, I will do miniaturization and optimization on it later, and it is estimated that it will become really useful in the third and fourth generations!"

Hearing Wang Jiancheng's answer, Chen Nian nodded in satisfaction.

When engaging in scientific research, especially in applied technology research, the biggest fear is that you are useless without knowing it.

But fortunately, now Wang Jiancheng still knows that he is useless.

So, he thought for a moment, and said:

"You exoskeleton, there are at least three areas that need improvement."

"First, the current purely mechanical transmission method must be abandoned. Although we all say that the mechanical structure is reliable, but at this level of complexity, the mechanical is far less reliable than the general electronic sensor."

"Too many connectors and bearings are likely to cause jamming and stagnation of parts after aging, which will affect activities."

"That's definitely not a problem that a full-fledged exoskeleton should have."

"Second, as you said, the size of the exoskeleton should be reduced."

"After all, what you make is to assist in combat, not to turn it into a weapon's 'mech'."

"Third, the application scenarios of passive exoskeletons are still too small. Now that you have figured out the structure, I suggest you go further and start making active exoskeletons directly."

Wang Jiancheng nodded repeatedly while holding a notebook, but after finishing writing, he couldn't help raising his head again, and said with a bitter face:

"Senior, I know all the things you said, but the problem is, I really can't operate it."

"The problem of electronic sensors is not too difficult, it can be solved with torque sensors."

"However, the use of electronic sensors means that the power system must also be changed. Hydraulics and servo motors are difficult to handle, and the complexity has also risen sharply."

"Not to mention the power source - in an active scenario, I can't engage in nuclear fusion, right? How many times can the battery last?"

Chen Nian scratched his head subconsciously.

The problem Wang Jiancheng said is indeed not small, but there is no solution?

Isn't Qiao Mai doing mechatronics?

Let her come over together!

If the problem of Wang Jiancheng's exoskeleton can be solved, then her electromechanical-hydraulic integration technology will definitely make a breakthrough.

After all, practicality is the biggest driving force for technology research and development.

Thinking of this, he said:

"You can go to Qiao Mai for the first two questions."

"She knows a lot more about this than you do and should be able to help."

"There is one problem left, the energy problem, I will find a solution."

"Give me three months, and I will make a battery that is enough for you!"

"real?!"

Wang Jiancheng widened his eyes in surprise, but soon asked in confusion:

"You have solved all the problems, so what should I do?"

Chen Nian was taken aback for a moment, then suddenly laughed again.

"You. I think you should do something you are good at."

"The maturity of Yujing 02 is already very high now, and you shouldn't just be satisfied with this level."

"Artificial intelligence is a very broad direction, and there are many application scenarios for it."

"I suggest you think about how to move artificial intelligence to the exoskeleton."

"Of course, I'm not talking about letting you build smart mechs."

"However, if there is a set of algorithms that can make the motor respond faster and have higher efficiency, then this set of algorithms will definitely increase the flexibility and combat effectiveness of the exoskeleton exponentially."

"Okay! Let's do it!"

Wang Jiancheng nodded sharply and answered.

From his eyes, Chen Nian saw a unique light.

He vaguely felt that this time, maybe in his hands, something epoch-making would really be born
