A big country of aerospace with black technology

Bishan, wireless power transmission demonstration base.

"Dean Zhang, long time no see."

Qin Yue, as the representative of the wireless power transmission BS area, greeted Zhang Xingyang very warmly.

The last time the two met was during a test flight of a high-altitude solar drone more than a year ago.

"Hello, Representative Qin."

After Zhang Xingyang responded, he didn't say anything more to her.

I asked the person in charge of the base directly.

"How are the preparations for the experiment? There must be no problems with the first ultra-long-distance wireless power transmission."

The person in charge of the base is also an old man who came out of the research institute.

"I've had it checked and there's nothing wrong with it."

"Before this, we have conducted wireless power transmission experiments at the 100-kilometer level, and the experiments were very successful."

"This time, we have enough confidence."

Zhang Xingyang looked through their experimental project checklist and said:

“Faith is not something you say.”

After confirming that there was no big problem, he raised his head and said:

"If the experiment fails due to your fault, you will be responsible."

Zhang Xingyang's tone was very calm, as if he was talking about a trivial matter.

But the person in charge of the base knew very well.

What does this responsibility mean?

If it was really because of him that the experiment failed.

Punishment may range from expulsion.

At worst, he has to go in and step on the sewing machine.

However, he boasts that he has done his job on the receiving end to the extreme.

So I wasn’t nervous at all, and I was even able to say with a smile:

"If it's really our problem, then you can always send me in."

Zhang Xingyang nodded and said nothing more.

There is actually not much that the ground receiving end can do.

This is an experiment in air-to-ground power transmission.

The point is actually in space.

The angle of the satellite is most important.

There can be no deviation for a minute or a second.

Because it is three hundred kilometers away in the sky.

At such a long distance, a deviation of one degree can cause a difference of more than five kilometers!

Even one second difference is 3600 degrees.

There will also be a difference of more than one second.

This places extremely high requirements on the transmission and positioning accuracy of satellites.

To solve this problem.

Zhang Xingyang and others have made a lot of efforts on satellites.

The latest third-generation Beidou navigation system is used.

The accuracy can reach 10 cm.

It is enough to meet the microwave positioning accuracy requirements of power satellites.

"The power satellite has completed preparations for power transmission."

In the control room of the experimental base, a familiar voice came from the microphone.

Air-to-ground wireless power transmission project.

There are several different departments involved.

This is why Zhang Xingyang had to come all the way from Beidu.

It is to facilitate the coordination of various departments.

Currently, it is Qin Ming who is in charge of the Beidu command center.

After Zhang Xingyang heard this, he turned to look at the person in charge of the base.

He is currently responsible for the work at the base.

Zhang Xingyang would not interfere randomly.

Anyone who has done anything knows that blind intervention is likely to cause uncontrollable problems.

"The receiving end of the transmission base is also ready for everything!"

The person in charge of the base said confidently and confidently.

Zhang Xingyang nodded when he heard this and said into the intercom:

"I announce that the first coordinated experiment in air-to-ground power transmission will begin now!"

Hundreds of kilometers in the sky.

An extremely huge satellite has accurately aimed its microwave transmitter at the intended target.

After receiving instructions from the ground command center.

The internal transmitter starts working.

Converter, converts electrical energy into microwaves that are easier to propagate and have low attenuation.

Microwaves are extremely fast.

is the speed of light.

Even in the atmospheric medium, it can reach nearly the speed of light.

The attenuation is very weak.

Almost at the moment the order was given.

The ground receiving end has already received the microwaves from space.

"The microwave positioning deviation is 1.12 meters and needs further adjustment."

Immediately someone quickly mentioned the issue with the microwave.

This is not a big problem for everyone present.

First coordination experiment.

This is to test these issues.

As long as the deviation is not too outrageous, everyone can accept it.

"Adjust now."

Zhang Xingyang asked the other party to transmit the real-time data to Qin Ming and the others.

Qin Ming and the others then relied on the data from Bishan Wireless Transmission Base.

Adjust the angle of the satellite in real time.

"The current receiving power is 5,200 kilowatts!"

The data monitoring team on the other side also came in with another data.

Compared to 6200 kilowatts in a vacuum environment.

This data is quite different.

But this is the first coordinated experiment after all, so the low power is not surprising.

If the weakening effect of the atmosphere on microwaves is taken into account.

This result is already very good.

The first coordination experiment did not last long.

It only lasted about ten minutes.

Then everyone began to analyze the data collected from the first experiment.

Engineers in the wireless power transmission base.

Also started to check the receiving end equipment.

Qin Ming and the others asked the power satellite to activate the self-test mode.

Power satellites operate in space after all.

Unlike ground bases, it is easy to detect at any time.

At most every once in a while.

Let the astronauts go up and conduct an inspection.

The core of the power generation satellite is actually a small space station core module.

In other words.

The power generation satellite is actually a space station with enhanced solar panels.

It's just that the main function of this space station is to transmit electrical energy to the ground.

It cannot accommodate people staying for a long time.

In Zhang Xingyang's plan, future power generation satellites.

There will be one to three astronauts stationed there for a long time.

They are the space power personnel of the new era.

However, their job is to look after space solar panels.

Just like the staff of a solar power station on the ground.

"There's basically no loss in the converter at the receiving end."

After completing the inspection of the receiving end, the person in charge of the base reported to Zhang Xingyang in person.

"Only one or two RF-DC gallium nitride converters were damaged and we have replaced them."

Such damage was within Zhang Xingyang's expectation.

The entire wireless power transmission receiving end has tens of thousands of RF-DC gallium nitride converters.

The damaged ones should have been defective products.

It cannot withstand ultra-high power wireless power transmission conversion.

during the previous inspection process.

Because the power is not high, it can be checked.

"Besides, are there any other questions?"

Zhang Xingyang was multitasking, looking at the experimental data in his hand and chatting with the person in charge of the base.

"Other than this small problem, there are no problems."

The person in charge of the base said quickly.

In fact, there are still minor problems in other aspects.

But these are not suitable to be said in the current scene.

For example, employee issues.

In today's society, there are many so-called experts.

It is claimed that the microwaves used in the wireless power transmission process have many side effects on the human body.

Even within the experimental base, rumors have been refuted several times.

But if refuting rumors worked, then there wouldn't be so many rumors that are deeply rooted in people's hearts.

Zhang Xingyang raised his head and glanced at the person in charge of the base.

Over the years, Zhang Xingyang has met countless people.

It can be seen just at a glance.

The other party definitely has something to hide from him.

But it doesn't matter, it probably has nothing to do with today's experiment.

Since it has nothing to do with the experiment, it's not a big deal.

"Inform Qin Ming and others in the lower northern capital to prepare for the second experiment."

Just now, Qin Ming and the others have also completed the self-inspection of the power satellite.

Sent word that everything was fine.

Half an hour later.

The second power transmission experiment begins.

It was a good sign from the start.

Microwave positioning accuracy directly reaches 0.25 meters.

The subsequent positioning accuracy was maintained between 0.1-0.2 meters after fine-tuning.

This kind of accuracy is enough for them.

Because the acceptable range of receiving error at the receiving end is actually 0.5 meters.

"Current receiving power, 5800 kilowatts."

The second time the microwave operating power increased a lot after the adjustment.

However, there is still some gap compared to the 6200 kilowatts in a vacuum environment.

Zhang Xingyang looked at the current data.

The data is very detailed.

It is even as detailed as the temperature, operating current, etc. of each gallium nitride unit in the receiving end RF-DC module.

And these data are accurate to three decimal places.

In the field of Seiko, this is considered very detailed data.

According to the current working power.

The receiving end can generate nearly 140,000 kWh of electricity every day.

Even based on the urban population, four kilowatt hours of electricity are consumed every day.

This can already meet the needs of nearly 35,000 people.

In fact, at this time very few people are able to use up to four kilowatt hours of electricity a day.

Most families are still very energy-saving.

Moreover, this time is not like twenty years later.

There are not many electrical appliances in every home.

It is different from the smart home life in later generations where everything is electric.

A power-generating satellite can meet the power demand of a small urban area.

This is for the country.

It's a very good thing.

This is especially true for the Dragon Kingdom.

Power consumption is very uneven.

Electricity consumption in the eastern coastal areas is several times that of the central and western regions.

However, these places cannot carry out large-scale solar and hydropower construction.

This is also an important reason why there is a West-East electricity transmission.

Now with microwave power transmission technology, this project will become easier.

Electricity developed in the West.

They can all be transported into space through microwaves, and then transmitted to the eastern region through satellites.

And power satellites can also adjust power in real time.

Power consumption in various regions can be dynamically balanced.

Don't waste resources.

"You guys did a great job."

The second experiment lasted longer, reaching two hours.

During this period, although the received power fluctuated slightly.

But this little bit can be ignored.

So Zhang Xingyang did not hesitate to praise:

"This experiment was a success thanks to your hard work."

At this time, the person in charge of the base finally let out a long sigh of relief.

For him, the success of the experiment was not the most important thing.

What’s important is how to gain leadership’s approval.

And the leader is Zhang Xingyang.

"The technology you developed is good enough, we are just doing a little bit of supplementary work."

The person in charge of the base flattered Zhang Xingyang.

Zhang Xingyang also noticed this, but didn't say anything more.

Although the person in charge of the base is a bit pandering.

But he did a pretty good job.

Zhang Xingyang didn't really care about his shortcomings.

Of course, if he doesn't do his job well.

Then you may have to face another scene.

"Dean Zhang, congratulations to you."

After the second experiment, Qin Yue, who had been watching for a long time, came up with a smile and congratulated him.

"Our cooperative project has been a complete success."

Zhang Xingyang was surprised to find that the other party had not left.

For such a long time, I have been busy with the power satellite.

Zhang Xingyang almost forgot that there was someone else here.

"Yes, our joint project was successful."

Zhang Xingyang stared into her eyes for a few seconds before speaking.

Everyone present is a human being.

Naturally, everyone can hear the different meaning in the other party's words.

This project is not theirs.

It is a cooperative project between them and the local government.

If the project succeeds, they also have a share.

What Zhang Xingyang just said confirmed this point.

Representatives will not abandon them and eat alone.

"But the technology of wireless power transmission does not belong to you."

Zhang Xingyang turned around and said calmly.

This is also true.

Wireless power transmission technology actually existed a long time ago.

It has already been registered by the Rocket Academy.

It’s just that what was registered at that time was ten-meter wireless power transmission technology.

However, Zhang Xingyang and others have also set up numerous patents on related technologies, forming a relatively large patent pool.

Among them, the most critical microwave-to-power gallium nitride converter technology has been firmly grasped.

It is even difficult for outsiders to know where these gallium nitride components are produced.

Considering that there are only a handful of units or companies in the world that are capable of mass production of gallium nitride components.

Zhang Xingyang and the others don't even particularly care about the existence of the patent pool.

As long as they have their gallium nitride technology in hand.

Even if it captures the technical core of wireless power transmission.

Don’t be afraid of others imitating it.

Even if someone completes the replication in the laboratory.

But large-scale industrial production is basically impossible.

"We have no ambitions, we just hope you can take us a share of the pie next."

Qin Yue said somewhat unexpectedly.

The two people present were a little surprised.

I originally thought that Qin Yue said that because he coveted their wireless power transmission technology.

Unexpectedly, their appetite is so small.

Turns out I just want to share some of it in the future.

In fact, consider the energy market across the country and even around the world.

So called a piece of cake.

It is also a huge market worth hundreds of billions.

"We are partners and I won't forget that."

Zhang Xingyang smiled at her and said.

Partners mean that they can still make money together in the future.

But how much meat can be left for them to eat.

That's hard to say.

In fact, Qin Yue and the others don't have big ideas.

As long as I can have a sip of soup.

A future energy giant is about to be born in these few words! (End of chapter)
