A big country of aerospace with black technology

As we all know, power generation in a power station merely completes the production process.

Want to complete sales and make profits.

You have to go online to sell.

At present, wireless power transmission projects are mainly carried out in mountain cities.

So they want to sell the power that the satellites transmit back to Earth.

It is inseparable from the State Grid.

"Director Lu, welcome!"

The boss of the local power grid company greeted me warmly.

Lu Zhenghe serves as the head of the Energy Bureau.

Before this, it was as difficult as going to the sky for him to see her.

"Mr. Ge, you don't have to be so polite." Lu Zhenghe said with a kind smile.

"I'm here today just to listen.

Don't be so nervous. "

Although Lu Zhenghe said this, General Manager Ge present would not take it seriously.

How could such a big boss just be a spectator?

I guess they came to support each other.

Fortunately, he didn't offend the other party.

The wireless power transmission project is jointly developed by BS Zone ZF and the Rocket Research Institute.

A company jointly held by both parties has been registered.

It’s called Galaxy Power Technology.

The main shareholder is the Rocket Research Institute.

It holds 72% of the shares of Galaxy Power Technology.

BS Zone ZF holds the remaining 20% ​​of the shares.

All Galaxy Power Technology employees hold the remaining eight percent of the shares.

However, employee collective shares only have dividend rights.

There is no right to vote.

"Mr. Ge, let's start as soon as possible."

Yang Yi said with a smile and grace:

“It would be a good thing for us to finalize this matter as soon as possible.”

Yang Yi currently serves as the CEO of Galaxy Power Technology.

Negotiations will be held with the local State Grid.

What they are going to discuss today is the issue of wireless power transmission to the Internet.

The wireless power transmission base in the BS area can now be connected to this power network.

However, the on-grid electricity price has not yet been negotiated.

Therefore, the entire network access work is still at a standstill.

"According to the current "Interim Measures for the Management of Subsidy Funds for Photovoltaic Power Station Operation and Maintenance", on the basis of the basic electricity price, we will provide a subsidy of 0.42 yuan for every kilowatt-hour of photovoltaic access to the Internet."

Although Lu Zhenghe was present, Mr. Ge did not dare to deviate from the scope of the management regulations.

According to the current routine operation, Yang Yi was given a very common subsidized price.

After a brief glance, he saw that Lu Zhenghe had no intention of saying anything.

Ge Yihui's little heart felt relieved a lot.

"Mr. Ge, according to our current photovoltaic grid price in western China, is our basic electricity price 1.09 yuan or 1.5 yuan?"

Yang Yi did not worry too much about the subsidized price.

Rather, it points directly at an issue that the other party avoids and ignores.

In fact, there are different standards for the price of Western Optoelectronic Internet.

The main criterion for distinguishing different standards is the local level of development.

In order to take care of some underdeveloped areas.

The state will subsidize an additional on-grid electricity price of 0.41 yuan.

For example, the institute invested and built a molten salt tower solar thermal power station in the northwest Gobi four years ago.

Because it is located in a remote area, the price of generating electricity from the grid is very high.

It reached 1.5 yuan.

And enjoys state subsidies for the photovoltaic industry.

The final online transaction price reached 1.92 yuan.

It’s a sky-high price.

"this"

Ge Yihui glanced at Lu Zhenghe who was accompanying him with some embarrassment.

“The place where the BS area is located is not within our special poverty subsidy area.”

Although Ge Yihui's face was facing Yang Yi.

But it made people feel that his eyes were actually on Lu Zhenghe.

"So according to the regulations, I'm afraid we can't give you more subsidies."

Ge Yihui used regulations to make matters clear, so even if others had objections, it would be difficult for them to express their opinions on the spot.

After listening to Ge Yihui's words, Yang Yi showed a bigger smile.

"Mr. Ge may not be particularly familiar with our power generation situation."

"The base we built in the BS area is not our power plant."

"It's just a transmission transfer base."

"Our solar power plant is in space."

"I think there is no place in the world more barren than the vast expanse of space."

Of course Ge Yihui knew that their power station was built in space.

But this matter has no precedent after all.

He didn't dare to make the decision on his own.

So he could only turn his attention to Lu Zhenghe who was sitting aside.

And he said tentatively:

"Bureau, do you think space belongs to the second-category subsidy standard area?"

Previous power stations were either on land or at sea.

It is very easy to tell how the regions are.

Just refer to his geographical divisions.

But space is particularly special.

It does not belong to any country or region, and it is difficult to divide it into one.

This is also where Ge Yihui is in trouble.

There is no precedent for such a thing.

The first one to make a decision will bear great responsibility.

Especially this kind of project involving a huge amount of money.

According to the data Ge Yihui learned before.

Galaxy Power currently generates nearly 150,000 kilowatt-hours of electricity every day.

This is just their current production.

Five times the number of new solar panels will be added soon.

That is, the complete production capacity is close to 900,000 kilowatt hours.

The annual power generation exceeds 320 million kilowatt hours.

So this seemingly inconspicuous price of a few tenths of a dollar per kilowatt hour of electricity.

Above this base number, it will suddenly become a figure of hundreds of millions of yuan.

This is why Ge Yihui’s first quotation gave a subsidized price for poor areas.

But only one type of standard is given.

No reason was given for the second category standard.

"Currently, our country is vigorously promoting the development of new energy industries, especially in the photovoltaic power generation industry."

After Lu Zhenghe experienced a long period of silence.

Finally started to express his thoughts:

"The space power generation industry is still a thriving blue ocean for us."

"We are the only ones in the world exploring such technology."

“Whether it’s subsidies for remote areas or support for high-tech power companies.”

"We should all give them more incentive in terms of power generation prices."

"Let more new energy companies invest in technological research and development."

Lu Zhenghe made it very clear.

Especially the last two sentences were almost spoken to Ge Yihui's ears.

Give them more subsidies.

We need to provide support in more aspects.

"In this case, the basic electricity price of Galaxy Power can be maintained at 1.5 yuan."

After the big leader spoke, Ge Yihui swallowed twice and said:

"At the same time, we enjoy our subsidies for photovoltaic power generation, and the final on-grid power generation price is 1.92 yuan."

After getting this price, Yang Yi was quite happy.

As a high-tech enterprise, they can actually get many preferential policies from the local area.

For example, the tax exemption policy for the first three years.

Just in terms of taxes, you can save tens of millions of dollars a year.

These are the upfront savings.

No dividends will be paid yet.

According to the consensus reached by Zhang Xingyang and several big guys.

Galaxy Power will be going crazy for the next while.

It will be installed at a rate of nearly one million per year.

Increase your own power generation.

In order to achieve this goal, even Galaxy Power's shareholdings will undergo certain changes.

A capital injection is required to issue additional shares.

"Thank you Mr. Ge for your strong support to us."

Yang Yi said with a smile.

"On behalf of all our shareholders, thank you."

"It's not easy for us to provide such conditions." Ge Yihui said pretending to be difficult.

"I hope you can recruit more employees from our local area."

This is actually a tradition.

The local area has given relatively favorable conditions, which naturally needs to stimulate local employment and consumption.

These days, some cities rely on a few large companies to drive employment and consumption.

"That's natural. We are a socially responsible company."

Yang Yi smiled and said.

"Besides, our current ratio of local employees is already very high."

The main personnel of Galaxy Power are the staff of the wireless power transmission receiving end experimental base.

The vast majority are locals.

Only a few researchers and managers come from elsewhere.

"Director Lu, I wonder what other plans you have next?

Do you want me to keep you company? "

After the negotiation meeting, Ge Yihui asked Lu Zhenghe slightly flatteringly.

Lu Zhenghe looked at the sun slowly setting in the sky: "We have to run the power grid in a few places next."

"I won't bother you."

The main purpose of Lu Zhenghe's trip was to provide the Xinghe Electric Power Station.

And the site of the platform is not just the mountain city power grid.

Galaxy Power will not be limited to just one mountain town.

"Director Lu, our next stop is going to Donghai City."

After leaving the headquarters of Shancheng Power Grid, Yang Yi found Lu Zhenghe and said.

"The situation in Donghai City may be more complicated."

As a modern metropolis.

Donghai City has a permanent population of tens of millions.

Urban residents alone consume hundreds of millions of kWh of electricity every day.

What's more, Donghai City also has extremely huge industries.

Need to consume more electricity.

Because of this, the power supply in Donghai City is insufficient all year round.

Especially in the summer.

During peak periods of electricity consumption, various districts and streets have to provide time-sharing power supply.

It has brought great inconvenience to the production of enterprises and the lives of residents.

Even though Donghai City will add a lot of installed capacity of power stations every year.

And some surrounding cities will distribute part of the power.

But it still can't keep up with the growth rate of his power consumption.

The next step for Galaxy Power is to establish several wireless power transmission receiving terminals in Donghai City.

Used for power regulation.

The newly launched power generation satellites next year will also add their own contribution to Donghai City's power supply.

Rocket Research Institute, Materials Experiment Center.

Zhang Xingyang is trying to prepare fourth-generation semiconductors.

Third-generation semiconductors currently used in power satellites.

Although it is very advanced.

But upon closer inspection, he also has a lot of problems.

When gallium nitride works, it consumes a lot of energy and generates a lot of heat.

These problems are particularly unbearable on power-generating satellites.

In particular, the heating problem even forced the Satellite Research Institute to specially design a large cooling system.

Zhang Xingyang is studying how to industrially prepare large-size fourth-generation semiconductors.

What are fourth generation semiconductors?

This question had an answer in the twentieth century.

Gallium oxide.

It has more powerful performance than gallium nitride.

Especially in terms of band gap, critical breakdown field strength and transparent conductivity.

All far exceed gallium nitride.

And under the same conditions, the energy consumption of the oxidant is one-third that of gallium nitride.

"The one hundred and twenty-second experiment failed again."

Su Xiao reported to Zhang Xingyang slightly frustrated.

During these hundreds of experiments.

They prepared more than two hundred pieces of gallium oxide.

However, they did not meet their expectations.

"Is it still a matter of size?"

Zhang Xingyang asked without raising his head.

"This time it was slightly better than the previous times, and 1.5-inch wafers were prepared."

Lidya Su took a bottle of water from the table, took a few sips and said.

"It's one-tenth of an inch bigger than before. It's worth encouraging. I'll give you a chicken drumstick tonight."

Zhang Xingyang said half-jokingly.

"Forget it, we have to conduct the 123rd experiment tonight."

After Lidya Su finished speaking, she touched her belly: "And I am losing weight recently."

"Let's not talk about this anymore. Is there something wrong with our preparation method?"

“Should we use the guided mode method?”

The current production methods of gallium oxide mainly include the Czochralski method, the optical floating zone method, the guided mode method, etc.

Different methods have their own characteristics.

However, they have not yet been able to produce large-sized raw crystals.

"We can only use the guided mode method at the moment."

Zhang Xingyang raised his head at this time and said:

"The Tila method requires an iridium crucible. Iridium is too expensive and easy to contaminate."

The Czochralski method is actually easier to produce large-sized raw crystals.

There have been laboratories that have completed similar operations before.

A large original crystal of gallium oxide was successfully prepared.

But this method cannot be mass-produced.

The price of the iridium crucible meant that he could only work in the laboratory.

Play with it as a toy.

"The optical floating zone method has extremely high requirements for optical systems. No scientific research institution or company in the world, let alone us, can produce an optical system that can easily melt raw material rods and single crystal seed crystals."

Zhang Xingyang said helplessly: "For us, the only method that can be used is the guided mode method."

The guided mode method is compared with the first two methods.

No expensive crucibles or complex optical systems are required.

However, there are extremely high requirements for process operations.

But it is also the most likely solution to achieve industrial production.

"But the guided mode method is really difficult. If there is a slight deviation, the originally directional growth of the crystal will grow crookedly."

Lidya Su said with some embarrassment.

The guided mold method places the melt and seed crystal in a mold with a built-in film.

By controlling the temperature gradient, the growth of the wafer is controlled.

It's relatively simple to say.

But because there are so many factors involved.

If you want to achieve industrial production, you must formulate a horribly detailed production regulations.

Zhang Xingyang did not continue after hearing this, but continued to look at his computer.

On the computer is a new gallium oxide manufacturing process.

Gallium oxide is produced by metal organic vapor deposition.

The method is not complicated.

Similar to the previous preparation of carbon-carbon composite materials.

It’s just that the base material changed to trimethylgallium and the gas changed to high-purity oxygen.

This method is simpler and cheaper to produce. (End of chapter)
