A Man of Science and Engineering in Troubled Times Wandering in the Late Qing Dynasty

Chapter 126 Dismantling
After a few months, Li Yu went to the Beiyang Armed Forces Crash School again.

Although today's demonstration has become a physics-biased demonstration due to Li Yu's arrival, 500 million taels is a very large number.Therefore, not only Yuan Shikai arrived, but also high-level Beiyang leaders such as Duan Qirui, Feng Guozhang, and Wang Shizhen were all present to attend the demonstration meeting in a large classroom in the school.

Several of them sat in the front row with Tang Shaoyi, while Zhang Xun, Cao Kun, Li Chun and others were in the back row.

These people are now the big men in the Beiyang Army. As for the young warlords, such as Sun Chuanfang, Wu Peifu, Li Jinglin, Cai Yubiao, etc. who are still students, they are watching from outside the classroom.

On the one hand, they heard that Yuan Shikai was coming, so they all wanted to see it; on the other hand, they wanted to see how their teacher, Mr. Li Yu, confronted the American "inventor".

"It's really exciting." Wu Peifu said.

"Yeah, it's rare to have a good show." Sun Chuanfang said, "Who do you think will win?"

Wu Peifu said: "It's hard to say. We have all seen the blueprints these days. It is so advanced that it is outrageous. If it can be realized, maybe our navy will be able to reproduce the glory of the year and defeat the Japanese."

Li Jinglin said: "That's a good relationship. I won't be in the army anymore. How awesome it is to be a navy captain!"

"It's so simple," Sun Chuanfang poured cold water on him, "If it's so good, why don't foreigners use it themselves? I think our teacher Li is right."

After everyone was seated, Feng Guozhang said: "Today is the final demonstration of Mr. John's zero-engine plan. If it can pass, Beiyang will start investing in research and development."

John couldn't wait to take the blueprints and plans to the podium, and he said: "My honorable officers, please rest assured that my plan is the most advanced, reliable and greatest engine plan in the world. The engine is the heart of a ship. In the future, it will definitely make Beiyang The navy becomes the supremacy of the seas.”

John started to paint a big pie, the bigger the blow, the more the fathers of Party A would be willing to give money.Of course, once the money is in hand, he will be the son of Party A!

And John is full of confidence, a bunch of big bosses, what do you know!
Feng Guozhang coughed: "In order to ensure the rigor of the argument, we solemnly invited Mr. Li Yu, who once taught Beiyang, as a special argumentator."

John was taken aback, Li Yu?teach?
Li Yu stood up, looked at John like a clown, and said, "Mr. John, please start the performance, oh no, start the speech."

John has been lobbying around during this time, and he doesn't read the newspaper much, and he doesn't know Li Yu's name yet.

——Of course, he doesn't really care about science, he only cares about where there are fat sheep waiting to be slaughtered.

John unfolded the drawings and pinned them to the blackboard.We have come to this point, we only need a finishing touch!
"My zero-engine plan uses liquid ammonia as the working substance, which can absorb the heat of seawater and turn into gaseous ammonia. Then the ammonia will generate 0 atmospheres of pressure at 4°C, and then push the piston to do work. You understand ?"

Li Yu said with a mocking expression, "I understand, you continue."

John felt that Li Yu was just mediocre. Like those before him, he couldn't ask anything when he was explaining the principle, so he just let him continue talking.

John said: "The same is true for steam engines. Pushing the piston can make the engine run. So you see, the energy is not using coal, but absorbing the heat of seawater, which is inexhaustible. But this This kind of research and development is time-consuming and money-intensive, 500 million taels is actually not much, the U.S. Navy spent more money back then, but as long as you give me time and money, I will definitely be able to..."

"Hey, wait a minute!" Li Yu interrupted him, "Why are you talking so much? You haven't finished explaining the principle yet, and it's about money all of a sudden. You should finish explaining the principle and plan first."

John said: "Isn't the follow-up simple? Ammonia pushes the piston to do work, it expands, and the gas expands, it cools, and then condenses back to liquid ammonia, and the cycle continues, and so on. I haven't drawn enough on this drawing. In detail? You see, I have shown how the engine works, and I will not continue to tell you about the operation of the engine..."

Li Yu interrupted him again: "I just said that you talk too much. I don't need you to talk about how the engine works. I only care about the issue of liquid ammonia and gaseous ammonia. As for the operation of the engine later, I don't need you to continue talking. "

Li Yu understood why John was able to bluff all the Beiyang big shots.

This kid really spent his money!
When he explained the plan to Yuan Shikai and others, he must have talked a lot about it, all the way to the details of the engine's operation.

If you say this, it is indeed easy for people who don't know much about mechanics to ignore the details of the power part.After all, the engine is a very advanced machine technology. Almost 90% of John's plan is related to the operation of the engine, and the previous part of the perpetual motion principle only accounts for 10%.

Yuan Shikai and the others had never studied mechanics, so of course they felt that what he said was all right.

And I don't know where John stole the engine blueprint, which is now a confidential design document.

Really clever!

This is the pinnacle of being a liar.

A superb liar will certainly not lie every sentence, but often there is only one lie in ten truths.

Ten truths or even a hundred truths are trusted, and one falsehood is the real core output.

This kind of routine was an extremely superb deception method in Li Yu's previous life and in the 21st century. It is indeed impossible to guard against, and there are many people who are accidentally tricked.

Even many institutions controlled by foreign forces that are deeply hidden, seem to be public welfare assistance, and have received the attention and support of many people, but in fact, once they start to mix in falsehoods and output content, it will be extremely harmful.

John asked: "Do you not understand the principle of the engine? If you don't understand, I can continue to tell you."

Li Yu sneered in his heart, my undergraduate degree is at least a double degree in mechanics and physics, so don't pretend to me.

Li Yu said, "I'll just ask you a question, as long as you can answer it."

"A question?" John was even less afraid, "You say so!"

Li Yu said slowly: "How can gaseous ammonia be transformed into liquid ammonia simply by expanding?"

John was stunned: "Because work has been done! Don't you understand the conservation of energy? If all the absorbed heat is used to do work, of course it will return to a liquid state again."

"Very good," Li Yu said, "After talking for a long time, you finally reached the key point. How do you use all the absorbed heat to do work?"

"Because, because I designed the insulation layer to prevent heat loss." John said stubbornly.

"Hehe! If all the heat is isolated, how will the work be transmitted outward? Also, friction, isn't there friction? Besides, the machine will heat up and absorb heat. Even if you insulate the heat, can you achieve a fully enclosed? Fully enclosed It makes no sense. And once there is air in it, the air will also absorb heat, how can you guarantee that all the absorbed heat will do work?"

Li Yu's series of questions made John stupid.

Li Yu naturally understood very well that even in his previous era, the power of the most advanced internal combustion engine was only a little over 40%, almost touching the upper limit of the heat engine.

Let alone now.

John murmured: "Friction... heat insulation, this, these should all be possible."

Li Yu smiled and said, "Aren't you full of confidence just now? How come you can talk and start to 'should'? Let me ask you again, do you know what the second law of thermodynamics is? If you don't, I can tell you about it." speak."

John knew that he had encountered a hard problem today. In fact, in this era, there are really not many people who know the second law of thermodynamics.

John said: "You don't have the spirit of contract! You clearly said you only asked one question, but why are you asking so many!"

Li Yu crossed his hands, looked at his impatience and smiled, "These are small questions extended from the first question."

Knowing that he couldn't continue to confront Li Yu, John turned to Yuan Shikai and the others and said, "My lord, I thought about it just now. In fact, 100 million taels can also be done. Let's try first, maybe we can make it, maybe Beiyang The navy can become the number one navy in the world! For this purpose, one million taels is not much to try!"

The faces of Yuan Shikai and others are already ashen, is it true that Nima is playing us like monkeys?
Seeing that they were silent, John continued to bargain quickly: "How about 50 taels, oh, 5 taels! This is the lowest price, let's try the head office! In case..."

Yuan Shikai was completely angry, and said to Wang Shizhen next to him: "Director Wang, as the chief of the military preparation department, you are in charge of the law enforcement department. How do you deal with deception in military law?"

Wang Shizhen said: "The amount is huge, and he can be shot. But considering that he attempted to do something, he should also go to prison for 15 years."

Everyone in John was dumbfounded: "Master Yuan, you... what are you talking about?"

Yuan Shikai shouted angrily: "Come here, put him in prison and keep him under strict supervision!"

Several big soldiers immediately ran in and set up John.

John quickly said: "Master Yuan, don't, or 1 taels is fine! Hey, don't drag me! Master Yuan, those blueprints of mine cost more than this amount... let me go!"

Yuan Shikai annoyed: "Pull it out!"

Knowing that there was no other way, John said instead, "You can't use private law to punish me. I'm an American citizen, and I'm protected by American laws. The embassy won't ignore me!"

"Oh?" Yuan Shikai said, "I remember when you told me that you secretly brought the plan out of the United States. It was so advanced that even the President of the United States had seen it. So no one will know about your visit to China this time, because you Taking such a big risk, letting the US judiciary know is also a serious crime."

John was completely stupid. He didn't expect to die in the hole he dug, "No! I'd rather you hand me over to the embassy. I want to go back to the United States. I want to go home, even if I go to a prison in the United States!"

Yuan Shikai said coldly: "Of course not! Don't worry, the treatment in our prison is definitely better than yours in the United States. And you will feel more about what a prison is!"

John gave up completely and began to curse in English: "Fuck, you can't do this to me!"

The big soldiers directly stuffed his mouth with cloth strips, "Spare yourself! If you are honest, the man will treat you well!"

John's face was full of despair, but he couldn't say anything, and he was dragged to the prison abruptly.

Yuan Shikai clasped his fists at Li Yu and said, "Thanks to Mr. Li Yu for helping me wipe out a foreign liar."

Li Yu replied: "It should be. To be honest, I hate foreign liars the most. My lord must lock him up, otherwise he will cheat everywhere."

Feng Guozhang snorted coldly: "This damn bastard tricked us, he will never get out of our prison in his life!"

Wu Peifu, Sun Chuanfang and others outside were completely excited:
"Let me just say, Li Jiaoxi will definitely win!" Sun Chuanfang said proudly.

Wu Peifu also said: "I really didn't expect that John lied to us for so long, and Li Jiaoxi took him to the bottom within ten minutes."

Cai Yubiao praised: "This is the teacher of a generation, and I will be such a person in the future!"

Li Jinglin touched his head and said, "I can't be a navy captain if I do this."

Li Yu pointed to the blueprint and said: "Although this design drawing and plan are wrong in the power part, there is nothing wrong with the engine transmission plan in the back. We just need to change the power part back to coal. I think we can use it , don’t waste it. Even if it can’t be used for naval ship engines, it can be used in many other places such as factories and mines.”

Yuan Shikai said: "I just don't know how to thank you sir, but you reminded me. In fact, we can't understand the blueprints. Now that John is gone, only you understand. The blueprints will be given to you! I just heard that you are also in the capital. In the university hall, you can use it for research, and it will be a blessing if we can really make our own engine in the future."

Li Yudao: "I heard from him that these blueprints were bought secretly and cost more than 1 taels. It's not appropriate."

"Why?" Yuan Shikai laughed, "Do you think 1 taels is not enough to thank you? If you feel that you are not sincere enough, we can give you more money."

Li Yu smiled and said, "Enough is enough!"
