Dreaming back to 1949, the great powers were there to deceive us

After Hu Zhenhua sent Jimla away, he continued to plan satellite matters. One of the important subsystems was the electrical system, which was to provide power to various equipment on the satellite and to enable communication and control between the equipment.

The electrical system consists of a power supply, distribution system, communications equipment, and control system. The power supply can be a solar cell, battery, or fuel cell. The distribution system distributes power to various devices. The communications equipment enables communication between the satellite and the ground station. The control system controls and manages the various devices on the satellite.

Hu Zhenhua pinched his chin and thought for a while, then decided to go to Jiuzhou Electronics Factory.

The factory was originally named Tongan Electronics Factory, but later, considering that the factory might be sanctioned in the future, Hu Zhenhua "donated" the factory to the county government. Now, Jiuzhou Electronics Factory is considered a state-owned enterprise, and its products include televisions and radios.

Carter agrees.

From the perspective of the red industry, it is more reassuring to produce products by ourselves, and it will be more secretive when we make some changes to the program.

Carter's calculations were good, but unfortunately, he didn't have a God's perspective.

Hu Zhenhua went to Jiuzhou Electronics Factory for two purposes. One was transistors, which were key components of the information revolution and had to be manufactured as soon as possible.

That’s right, it’s manufacturing, not R&D.

The transistor was invented in 1947 at Bell Labs by William Shockley, John Bardeen, and Walter Brattain.

They were awarded the Nobel Prize in 1956 for this invention.

Coincidentally, Hu Zhenhua also knew how to manufacture this basic component.

Therefore, there is no need for research and development, and you can directly explore manufacturing.

The principle of this thing is extremely simple. It is just a switch. When a micro voltage is applied to the PN junction, the transistor circuit is energized. When the micro voltage on the PN junction is removed, the circuit is de-energized.

Before the invention of transistors, vacuum tubes were used in the communications field.

Electron tubes utilize thermionic emission, with an internal vacuum filament heating the electron-emitting region. A grid-controlled electric field regulates the current. Transistors utilize the conductive properties of a PN junction to control current flow, with the magnitude of the current controlled by adjusting the control circuit. Transistors offer low power consumption, high efficiency, high reliability, and long lifespan. Their compact size can significantly reduce the physical size of circuits.

Following Moore's Law, the size of transistors shrinks by half every 18 to 24 months, and processor performance doubles approximately every two years, while prices drop to half of their previous levels.

Hu Zhenhua’s second purpose is for solar panels.

According to the original trajectory, the first solar panel would be produced at Bell Labs in 1954.

Hu Zhenhua naturally couldn't remember this incident, but that didn't stop him from intercepting it.

The principle of the first generation of solar panels is very simple. When solar photons hit a specific material, they knock electrons away, forming electrons and holes. By using different materials, the electrons and holes are attracted to two directions, thus forming positive and negative electrodes.

In solar cells, a small amount of boron is usually doped into silicon to form a p-type semiconductor, and a small amount of phosphorus is doped into silicon to form an n-type semiconductor, and photoelectric conversion is achieved through the pn junction.

Keep it simple.

Science is sometimes like this. When you look back, it seems quite simple, but before that, it was impossible to figure it out.

Chang Luo, director of Jiuzhou Electronics Factory, and Hai Ming, chief engineer, took Hu Zhenhua on a tour and then introduced him to the laboratory.

Without any delay, Lao Hu immediately took the lead in forming two confidential teams to manufacture samples of transistors and solar panels.

Large-scale production is still a long way off, but it's possible to make small quantities for research.

……

Qasim Road is named in memory of Mr. Qasim, an American engineer at the steel plant. He demonstrated internationalism, brought a large amount of technology and production processes, and made important contributions to the technological upgrading of the steel plant.

Although he was transferred back to his country, the people will not forget him.

Of course, this is external publicity. The truth is that Guo Dachong fed him well, and in just three months, he received a salary of over one million yuan.

Qasim was afraid that his crime would be exposed, so he found an excuse to return home and enjoy life.

Qasim Road is inhabited by Western businessmen, and one of Jimla's offices is located at No. 12 Qasim Road.

After receiving the report that Hu Zhenhua was staying at the electronics factory, the white intelligence chief was puzzled. He had asked Hu Zhenhua to borrow money before, not because he was short of money, but to test him.

The information about the big firecrackers was first leaked by Hu Zhenhua, so Jimla suspected Hu in this incident.

And now that Jimla has told the other party that he wants to pay, it stands to reason that Hu Zhenhua should take action, right?

However, this guy stayed in the electronics factory and hung out with engineers, and there was nothing unusual about him.

Jimla fell into self-doubt.

"Could it be that this matter really has nothing to do with him?"

It’s not that Hu Zhenhua is not interested, but he just can’t take care of it. The first solar cell is about to come out, so he has no time to pay attention to other aspects.

Compared with the progress of science, defrauding a little money is just a drizzle.

Sometimes, luck is really important.

If Hu Zhenhua shows any abnormality, his company will be doomed.

After Jimla ordered someone to put the four withdrawal slips in the designated location, he received a call from the other party.

"Mr. Jimla, the following information concerns the time and location of the experiment. May I ask how much you are willing to pay?"

Jimla pondered for a moment and asked,

"What if I only buy the location or the time?"

There was a laugh from the other side, and it was obvious that the other party disagreed.

Now that we know the location, the worst that can happen is that we can just wait there slowly. With the CIA's strength, we can always get time for testing.

Once we know the time, we can summarize the information based on the target's movement and infer the test location.

"Mr. Jimla, I want gold this time. Please quote!"

Why gold?

The reason is simple. Funds of tens of millions can be spent quietly, but hundreds of millions will be very troublesome, and the banknotes can also be tampered with.

But gold is different. Once it is slightly melted, its ownership cannot be determined.

The phone in Jimla's hand seemed to weigh a thousand pounds. He tried to calm himself down and said,

"Raising gold would take too long, and it would be hard to explain to the higher-ups. If you understand our system, you'll understand that once the report reaches Congress, it will require a long debate and no results will be achieved in the short term. To close the deal quickly, let's pay with rice."

The other party was silent for a few minutes, then spoke again.

“Okay, please quote!”

Jimla breathed a sigh of relief. In fact, in order to obtain relevant intelligence, the country has begun to spare no expense. If the other party insists on gold, the country may agree.

But it is ultimately in the interests of the United States that there is no US dollar, because the US dollar is printed, and the worst that can happen is that more can be printed.

Jimla calmed down and said loudly,

"2 billion yuan!"

This offer made the other party laugh out loud, and the sound was particularly harsh in Jimla's ears.

He also knew that this offer was impossible, but when doing business, one has to bargain.

After two minutes, Jimla asked back,

"How much do you want?"

"If it's gold, 500 tons. If it's US dollars, 10 billion! Mr. Jimla, I'll call you again in 24 hours. I hope to hear good news from you then."

The other party was about to hang up the phone when he suddenly remembered something and said,

"I'm giving you a free message. The earlier you pay, the earlier you can process it. Hurry up, bye!"

The beeping sound from the phone made Jim pull his teeth in pain.

He wanted to chat a little more to get some information out of the other party, but the other party didn't give him any chance.

Judging from what the other party said, the polar bear experiment should be progressing very quickly.

Report it!

……

At Jiuzhou Electronics Factory, after more than thirty hours of hard work, the first solar panel was finally produced.

The four people in the lab cheered.

Although the voltage difference is only 0.5V, this has achieved a breakthrough. Next, we just need to continue experimenting to find the best ratio.

Hu Zhenhua could no longer help with future work, and he wanted to leave, but Gao Yun refused to let him go and insisted on asking him to continue giving guidance.

Old Hu had no other choice but to rack his brains for several hours before he suddenly asked a soul-searching question:

"Doctor Gao, what do you think? If we reverse this and allow the electrons and holes to reunite, will they be able to emit light in turn?"

Gao Yun is not a poor student like Lao Hu, he understood immediately and shouted,

"Yes!"

There is a famous saying in the world: Genius is 1% inspiration and 99% perspiration.

But there is another sentence after that, which many people have not heard, which is 'But that 1% of inspiration is the most important, even more important than the 99% of sweat.'

Lao Hu's soul-searching question opened the door to a new world for Gao Yun, a chemistry PhD who had returned from overseas.

When electrons and holes meet, they emit light. This is the principle of light emission of LED lights.

Hu Zhenhua patted Gao Yun's shoulder, looked at his two students, and said with a smile,

"You three have already made history. Keep up the good work! I'm rooting for you!"

Solar cells and LED lights have each produced several Nobel Prize winners.

Now, Jiuzhou Electronics Factory is in a leading position in these two fields.

Hu Zhenhua suddenly remembered something and said,

"From now on, these two projects must be kept strictly confidential. I will provide you three with bodyguards and nannies, and I will also designate your laboratory as a restricted area. These are key projects that will elevate our country's scientific status, and no one is allowed to leak any information!"

Gao Yun had no objection. He looked at his two students and warned them,

"You two can talk about dating, but don't get carried away and say anything you shouldn't!"

"Teacher, don't worry, we can tell the difference between the important and the unimportant!"

Gao Yun turned to Hu Zhenhua and suddenly found that Old Hu had disappeared. He hurriedly chased after him and shouted loudly,

"Chairman, I still have details to discuss with you!"

When Lao Hu heard this, he ran even faster and ordered Lan Shian to stop Gao Yun.

As the saying goes, don't pretend to be cool, or you'll be struck by lightning.

Future generations will never deceive me!
