"Are you sure there's a gold mine?"

In the Western University of Technology, Chen Guo said into the phone with excitement on his face.

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

"Yes, there is, but the reserves and grade are not easy to say."

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

"Coupled with the fact that this area has never been exploited on a large scale, we judge that the reserves in this area should not be too low."

"Now that the strategy has been basically formulated, we will put forward this condition on the offer of the Gauteng high-speed rail and strive to win the project."

"If the project can be won, we need the full cooperation of the DPD Office - or rather, your Spark team."

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

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

"Understood!"

Chen Guo replied solemnly.

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

In essence, it is a springboard for China to move towards Africa, and it is also the way in which we "pass on the economic crisis" unlike the United States.

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

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

Or is it that the resources are not used up, but the resource dividends are eaten up?

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

So, involution, so it was born.

In essence, the ultimate impact of the economic crisis is involution.

In order to solve this problem, it is necessary to find an outward breakthrough for those excess capacity, whether it is to match them with more resources or to give them a larger market, which can be regarded as 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, the country that has enough output capacity will continue to develop steadily and at a high speed for more than a decade or even decades.

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

In fact, what they value is the "opportunity" itself.

If we can get the Gauteng project, which is a groundbreaking infrastructure project in Africa, and make a big promotion 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 be related to us in the future.

And if you can't get it

It will be much more difficult to find a project with the same role to open up the situation

Thinking of this, Chen Guo breathed a sigh of relief.

Now, after the existence of the gold mine has been confirmed, the last scruples of the superiors have been dispelled.

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

But if they can take the big piece of the African pie, what about after that?

The European Raiders should also start operating.

Although they don't need infrastructure assistance, they certainly still need communications, machinery, electronics, energy and other products.

All we need to wait for now is an opportunity like the Gauteng project

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

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

As for the further research content of lithium dendrites, it is necessary to wait for him to independently complete most of the preparation experiments of advanced energy materials and fully grasp the principles before he can carry out.

According to his own estimates, this time will take at least 3 months or more.

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

Chen Nian can feel that while this system instills knowledge, it has indeed improved his thinking activity to a certain extent.

This allows him to think faster and think more broadly 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, the corners of Chen Nian's mouth couldn't help but show a smile.

No one wants to be a slave to the system, and now he is working 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, and at this moment, he noticed the mobile phone that kept flashing on the bedside.

It was the one that belonged to him-—— someone called.

Chen Nian picked up his mobile phone and saw that it was Wang Jiancheng who was calling.

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

"Senior! The mechanical exoskeleton has been made! Would you like to check it out? ”

"What's that?"

Chen Nian was shocked.

Is this made?

That's too fast, right?

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

Carefully calculated, it has been half a year since Wang Jiancheng proposed to make a mechanical exoskeleton.

Removing his usual study and work time, it is not difficult to save an exoskeleton.

But to what extent. I'll really have to check it out for myself!

So, Chen Nian hurriedly continued:

"Where? Where do I go? ”

There was a faint excitement in his voice.

Obviously, no matter how much his reason told him that "this is just a preliminary attempt", "this thing is not an epoch-making product", and "the mechanical exoskeleton is not very useful at the moment", in terms of emotion, there is still no man who can refuse a mecha.

Even if it's a beggar's version.

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

"I rented a single room outside the school for a laboratory, I'll tell you the address, just come over!"

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

got Wang Jiancheng's address, Chen Nian quickly hung up the phone, and then rushed to the address he gave non-stop.

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

Chen Nian arrived quickly, pushed open the door and looked, he was immediately stunned by the scene in the room.

It was a mess, with all kinds of parts piled up everywhere, and there were several small operating stations with different functions on the floor, some specialized for cutting, some for milling, and some for grinding.

There are countless other tools, such as angle grinders, electric drills, hand saws, welding guns. It's all available.

He glared and asked in disbelief:

"You saved it all?"

"Yes! I've got all the tools, and if I have enough time, I can make any gadget! ”

Wang Jiancheng on the side replied with a proud face.

Then, he pulled Chen Nian towards the depths of this "mechanical forest".

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

Bypassing a large number of operating tables, Chen Nian finally saw the exoskeleton that Wang Jiancheng called "Mingguang No. 1".

At this glance, he found that he was still thinking conservatively.

The thing stands at a height of more than two meters, and its arm span may even exceed two meters.

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

Overall, it looks oppressive, but there's a little bit of it. Nondescript?

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

"You. It's not like an exoskeleton, it's not like a mecha, and it's not like Mingguang armor. ”

"It's up to you to make it. How did you design this drive? ”

"Purely mechanical!"

As he spoke, Wang Jiancheng laboriously "climbed" onto the exoskeleton.

As he fastened the various connecting structures, Chen Nian also saw how this mecha worked.

In general, like the passive mechanical exoskeleton of later generations, the basic design idea of this exoskeleton is to transmit the force located in 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 mechanically driven.

It relies entirely on the user's own strength to do the initial start, and the user not only needs to bear the gravity of the heavy object first when lifting the heavy object, but also needs to fight against the weight of the machine itself.

Where is this effortless?

It's really labor-saving to move it, but the problem is, you have to be able to move it too!

Watching Wang Jiancheng laboriously perform walking, grabbing, and other operations, Chen Nian couldn't help but have a thought flashing through his mind:

Why is this brother so similar to Handmade Geng?

It's not going to end up being a bunch of things he doesn't have, right?

But before this thought could turn around, Chen Nian was suddenly stunned.

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

Even each finger can be moved individually.

This means that the transmission mechanism of the entire exoskeleton is designed with extreme precision.

Could this be the legendary "delicate waste"?

Chen Nian hurriedly stopped Wang Jiancheng's experiment, laboriously rescued him from the exoskeleton, and then spoke:

"At first glance, this thing is quite handsome, but the practicality is really poor, and at present, it has no meaning at all!"

"Yes, yes! I also don't think this is practical, so it's just Mingguang No. 1! ”

Wang Jiancheng replied solemnly.

"However, I will optimize it for miniaturization later, and I guess it will be able to become useful when it comes to the third and fourth generations!"

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

When engaging in scientific research, especially scientific research in applied technology, the most fearful thing is that you are useless and do not know it.

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

So, he thought for a moment, and then said:

"Your exoskeleton, there are at least three things that need to be improved."

"The first one, now the purely mechanical transmission mode 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 after the aging of the parts, which will affect activities."

"This is definitely not a problem that should be with a full-fledged exoskeleton."

"The second, as you said, the exoskeleton should be smaller."

"After all, you're making something that's meant to be used as an aid in combat, not a 'mech' that turns it into a weapon in itself."

"Third, the application scenario of passive exoskeleton is still too small, since you have figured out the structure, then I suggest you go one step further and start making active exoskeletons directly."

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

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

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

"However, with the use of electronic sensors, it means that the power system also has to change, and hydraulic and servo motors are difficult to do, and the complexity has skyrocketed."

"Not to mention the power source – I can't do fusion in an active scenario, right? How many times can the battery stand up? ”

Chen Nian subconsciously scratched his head.

The problem Wang Jiancheng said is indeed not small, but it is not impossible?

Isn't Qiao Mai engaged in mechatronics?

Let her come along!

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

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

Thinking of this, he opened his mouth and said:

"For the first two questions, you can go to Qiao Mai."

"She knows a lot more about this than you do, and that should help."

"There is one remaining problem, the problem of energy, I will find a way to solve it."

"Give me three months, and I'll make a battery that's big enough for you!"

"Really?!"

Wang Jiancheng's eyes widened in surprise, but he soon asked a little confused:

"You've solved all the problems, so what am I going to do?"

Chen Nian was stunned for a moment, and then suddenly laughed again.

"You. I think you should do something you're good at. ”

"Now that Yujing 02 is at a high level of maturity, you shouldn't be satisfied with just this level."

"Artificial intelligence is a very broad direction, and its application scenarios are also many."

"I suggest you think about how to bring artificial intelligence to exoskeletons."

"Of course, I'm not saying that you should engage in intelligent mechas."

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

"Good! That's it! ”

Wang Jiancheng nodded violently and replied.

From his eyes, Chen Nian saw a unique light.

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