The Red Era, the Opening University Speech

Chapter 344 The Last Piece of the Big Mushroom

"Let's solve the electricity problem first." Li Mu planned secretly.

Originally he planned to build a power station.

This time it happened by chance.

"But I still have to find information from the chat page. With the information I have now, it is difficult to solve this problem." Li Mu felt a slight headache when he thought of this.

Now Ask is still wandering around with the little rich woman, and it is hard to say whether he can find relevant information about electricity.

Just when he was worried.

Suddenly, there were two knocks on the door of the archive room.

Li Mu looked up when he heard the voice.

It's Deng Jia and Yu Ming:

"It's time to rest, Consultant Li. We can continue our work tomorrow."

"That's right. After all the hard work, at least get a good night's sleep first and then start research tomorrow."

"Okay." Li Mu put down the documents in his hand, then stood up and followed them away.

……

Along the way, Deng Jia seemed to want to say something but stopped himself several times.

Obviously he wanted to ask about Li Mu's gains.

But after hesitating for a while, he still didn't speak.

After all, it's only a few hours, what big gains can there be?

Li Mu naturally discovered his thoughts.

But I have to pretend not to see it.

Although after reading the materials and combining them with the knowledge he learned from later generations, he did have some ideas.

But the content is too fragmented and lacks in-depth research, so it’s better not to bring it out to make people laugh.

And it’s okay to fool ordinary experts and sales.

But in front of top bosses like Deng Jia and Yu Ming, if you give him some ideas, he might be able to come up with a lot of things in an instant.

It would be a bit awkward if what he came up with didn't match the other two's ideas and he didn't know the answer to any questions.

……

Walked for a while.

The three of them came to a small building.

After passing the guard's inspection, go up to the second floor.

Deng Jia took Li Mu into a room and said:

"From today on, you will live here. Yu Ming and I will live next to you. If you need anything, you can always tell us."

"You've worked hard all day, you must be very tired, take a rest."

"Someone will bring you some hot water in a little while."

After he finished speaking, he turned and left.

"Take care, both of you." Li Mu let the two of them go.

Just about to go back to the room.

But he found that the two did not go to rest, but went downstairs and walked towards the experimental building in the distance.

It looks like I'll have to study until very late before coming back to rest.

"Not bad." Li Mu was slightly happy.

If you can endure this much, then you won't have to worry about your research time being limited.

Moreover, both Guan Jianmin and Zhao Canjun were arranged to other places, so they didn't have to worry about being watched anymore.

Just when he was feeling happy, suddenly, a voice rang out from behind him: "Advisor Li, come here, the water is ready for you, go take a shower and go to bed."

"Why are you here too!" Li Mu turned around.

It turned out to be Guan Jianmin, and behind him was General Zhao.

Didn’t you say you were assigned to another dormitory?

Guan Jianmin snorted and said, "Your words really make me sad. As your 'housekeeper', how can I not follow you?"

These words left Li Mu speechless for a moment.

It seems that what you said makes sense.

"Okay, stop being weird." Officer Zhao patted Guan Jianmin on the shoulder, then stepped forward to explain, "Director Deng was originally planning to arrange for us to move to other dormitories."

"But at our strong request, they agreed to let us live in the same dormitory building with you."

"The room at the top of the stairs is where Jianmin and I live. If you have any problems, you can just call us."

After saying that, he pointed to the first room after going upstairs and turning towards Li Mu's room.

"I see." Li Mu sighed with a little regret.

I thought I could get rid of Guan Jianmin's "surveillance".

But it's not a big problem.

When everyone is good at staying up late.

He has plenty of ways to make himself stay in the laboratory reasonably and legitimately.

Not to mention, the generals are not subject to military orders when they are abroad.

This place is a long way from Kyoto. By the time Guan Jianmin's report is sent over, he might have already boarded the return train.

……

Return to the room.

Li Mu quickly washed up and lay down on the bed.

Open the chat page.

Preparing to contact Ask.

Suddenly, a message alert sound rang in my mind.

It was Ask who sent the message first: "Li, something terrible has happened, I have to go back to the lab!"

"What's going on?" Li Mu was stunned at first, then joy appeared in his eyes.

If Ask returned to Jianqiao County where the laboratory was located, it would mean that he would regain access to the vast academic resources there.

Can't download though.

But he can remember it with his brain!
Ask:
"The shareholders there saw that I hadn't been back for so long and asked me to go back immediately to conduct experiments."

"What is going on? I think the rich girl is about to give up."

"You said, should I delay it any longer?"

Looking at the message sent by Ask.

Li Mu replied without even thinking: "Why delay? Absolutely not!"

"Ah, why is this?" Ask asked puzzledly.

If I go back now, all my efforts not long ago will be wasted.

Hearing this, Li Mu took a deep breath and calmed himself down from his excitement.

He thought for a while and said:

"Since the little rich girl is already showing signs of being unable to hold on, you can't go too far."

"Do you really want to be unable to be friends with her?"

"Why not go back now and lock yourself in the laboratory to do research? Once the research is completed, continue with the current method. Repeat it a few times and she will definitely give up."

This reason is a bit far-fetched though.

But it is just right for Ask.

"You're right, if we're just friends, I still like her!" After hearing this, Ask immediately realized what was going on and agreed.

……

End the chat.

Li Mu thought about it and opened the WIFI list.

He had never heard of the place where Ask was now, but the text was still in English, which meant that it was most likely with Emperor M or the Big Infant.

But this is not important.

What's important is that the laboratories here focus on life sciences. Although there are other laboratories, they are quite rare, and there are no laboratories that specialize in atomic energy research.

He has basically searched all the WIFIs these days, so he naturally knew this a long time ago.

But the absence of laboratories to study atomic energy does not mean that there is no relevant information in this area.

Li Mu entered the library's database and searched for relevant information about the centrifuge.

In this way, he can at least have a rough understanding of the historical development of centrifuges.

The application of centrifuge in giant mushroom research can be traced back to the early 20s.

It is mainly used in the process of uranium enrichment, which uses centrifugal force at very high speeds to forcibly extract uranium.

In the early stages, uranium enrichment centrifuges mainly used the gaseous diffusion method.

This method allows uranium hexafluoride gas molecules to diffuse through a diffusion membrane covered with micropores. Since uranium hexafluoride gas molecules composed of uranium-235 are slightly lighter and have a slightly faster speed, the proportion that passes through the diffusion membrane is slightly larger than that of molecules composed of uranium-238, thereby achieving enrichment.

However, this method consumes a lot of electricity.

This is also one of the main problems currently faced by the Deng family and others.

Li Mu read on and soon found a method that could solve this problem - gas centrifugation.

……

Two days passed by in a flash.

In the archives room.

Li Mu sat at a table, still looking at the documents.

Although he had already finished reading it, he was not in a hurry to let the Deng family and others know about it.

——Because Ask just returned to the laboratory yesterday.

He has some idea of ​​his own level and is not completely sure about it, so he will not easily contact the research leaders in the base.

in his thoughts.

It will take at least another three days before we can discuss this with the Deng family and others.

Otherwise, it would be embarrassing if it was discovered to be a parallel import.

Although with his current achievements, even if he fails once, it won’t be a big problem.

But in order to succeed, you still have to ensure the success rate.

After all, Xia Country really needs to produce the big mushroom as soon as possible to increase its own safety.

……

It's almost noon.

Li Mu walked out of the archive room and prepared to go to the cafeteria for dinner.

This was a time he had chosen specially.

Finish eating early so that the remaining food can be distributed evenly.

Otherwise, the aunt who was ordered by the Deng family to serve the food would not touch the food prepared specifically for him even if she waited until there was no one around.

Come to the dining hall.

There was hardly anyone inside.

The researchers in the base also have fixed meal times.

I'm still studying at the moment and won't come over.

After Li Mu finished his meal, he found a place to sit down.

While eating, he continued to review the research on centrifuges in his mind.

"The power generation technology in the 60s was still mainly based on thermal power generation and hydropower generation. Although atomic power generation has developed, it is definitely not up to the current level of Xia Country." Li Mu said in his heart.

To solve the electricity problem, it is not enough to save energy through gas centrifugation alone; we must continue to increase electricity sources.

As for the open source approach, there is currently only one method that is most suitable - thermal power generation.

Hydropower also requires building a hydropower station, which requires too much time and cost.

"Currently, the best thermal power unit in China is the first 20 kW steam turbine unit produced by the steam turbine factory in the three provinces. However, overseas, 30-60 kW thermal power units have been put into operation one after another." Li Mu checked the information.

Although thermal power generation will cause great pollution.

But for the current Xia Kingdom, it is a choice that cannot be ignored.

He quickly found information about the thermal power units built around the 70s, a 66 kW thermal power unit invested and built by the Drexel Thermal Power Plant.

锅炉处理达到2100吨/时，过热蒸汽压力166大气压，采用5缸6排汽或4缸4排汽设计……

"The material requirements are a bit high!" Li Mu looked at the information and found it a bit difficult.

In order to build this 66 kW thermal power unit, we need to solve not only technical problems but also material problems.

More importantly - it takes too long.

It would probably take more than half a year to make it.

"Supercritical and ultra-supercritical unit technology? That seems to be a solution." Li Mu turned to the technical aspect.

These two technologies refer to units in which the parameters of the working fluid in the boiler reach or exceed the critical pressure.

The working fluid in the boiler is water, the critical pressure of water is 22.129MPa, and the critical temperature is 374℃.

At this pressure and temperature, the density of water expanded due to high temperature and water vapor compressed due to high pressure is the same, which is called the critical point of water.

If the working fluid pressure in the furnace is greater than this pressure, it is a supercritical boiler.

The steam temperature in the furnace is not less than 593℃ or the steam pressure is not less than 31MPa, which is called ultra-supercritical.

Both have significant energy-saving and environmental improvement effects, and are technologies widely used in industrially developed countries in later generations.

“We can discuss it.” Li Mu thought about it and added it to the list of options.

Just when he had let go of his worries.

Suddenly, a man sat down in front of him.

"Director Deng, why are you here so early today?" Li Mu raised his head, saw who it was, and greeted him.

The latter shook his head and smiled, "There's nothing I can do. If I can't find an idea, it's useless to stay in the lab. It's better to eat early and fill my stomach first."

"You're right, health comes first." Li Mu nodded slightly.

The Deng family originally wanted to ask him how things had been going over the past two days.

Hearing this, I was a little amused and confused.

How could he not know that health comes first?

After thinking about it, I just said:
"By the way, Consultant Li has been looking at the information for two days. Do you have any ideas?"

"No need to be too perfect, just say it casually."

"We really don't have any good ideas now."

After he finished speaking, there was hope in his eyes.

The feeling of being blocked in research and losing direction is really tormenting.

"As for the method, it only takes two days. I dare say, do you dare to believe it?" Li Mu hesitated and said.

Although the problem is not completely solved.

But it’s not impossible to give some things and let the Deng family and others study them first.

When the Deng family heard that there was a chance, they quickly said, "Why don't you believe it? As long as Consultant Li opens his mouth, I will immediately call everyone over to hold a meeting to discuss it!"

"No, no, it's just an idea, there's no need to make it so formal." Li Mu thought for a moment, then said, "Do you think there is room for improvement in the gas diffusion method used in our current uranium enrichment centrifuges?"

"Improve it? But we just made the breakthrough not long ago, and now Emperor M and Big Brother are also using the same technology!" Deng Jia was silent for a moment.

The gaseous diffusion method took them several months to solve.

If improvements are made, it will probably take several more months.

Li Mu said:
"The gas diffusion method separates isotopes based on the different diffusion rates of isotope molecules through pore membranes. It uses a separation membrane containing a large number of micropores to allow gas molecules to freely pass through these micropores without colliding with each other under certain conditions."

"Because lighter molecules have a greater thermal motion speed, the lighter isotopes can be enriched to a certain extent after the separation membrane, but the energy consumption of this method is really too high."

"Then can we change the angle and separate isotopes based on the different equilibrium distributions of gas molecules with different masses in the centrifugal field?"

After he finished speaking, he looked at the Deng family quietly.

The latter frowned and pondered for a long time, sometimes relaxing, and sometimes twisting his brows fiercely.

After a long time, he suddenly realized and clapped his hands fiercely:

"Good idea, good idea!"
