After a few months, Li Yu went to the Beiyang Military Preparation Crash Course again.
Although today's argument turned into a physics-based argument due to the arrival of Li Yu, 5 million taels is a big number. Therefore, not only Yuan Shikai arrived, but also Beiyang senior officials such as Duan Qirui, Feng Guozhang, Wang Shizhen, etc.
Come together and attend the demonstration meeting in a large classroom of 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 big bosses 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 in person and 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 drawings in the past few days. It is really so advanced that it is outrageous. If it can be realized, maybe our navy can reproduce the glory of the year and defeat the Japanese."
Li Jinglin said: "The relationship is great. I won't be in the army. It will be more majestic to be a navy captain!"
"It can't be that simple," Sun Chuanfang poured cold water on him, "If it's so good, why don't foreigners use it themselves? I think it has to be our Professor Li."
After everyone was seated, Feng Guozhang said: "Today is the final demonstration meeting for Mr. John's zero engine plan. If it can be passed, Beiyang will start investing in research and development."
John couldn't wait to hold the drawings and plans and walked to the podium. He said: "Dear 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 the ship. In the future, it will definitely be able to make Beiyang
The navy became the overlord of the sea."
John started to spread the pie, and the bigger he blew it, the more willing Party A’s fathers were to give money. Of course, once the money was obtained, he would be Party A’s son!
And John is full of confidence. What do you know about a bunch of rough guys?
Feng Guozhang coughed: "In order to ensure the rigor of the argument, today we solemnly invite Mr. Li Yu, a former teacher from Beiyang, as a special argumentator."
John was stunned, Li Yu? Teach?
Li Yu stood up, looked at John like a clown and said, "Mr. John, please start performing, oh no, start giving a speech."
John has been lobbying everywhere during this time, and hasn't read much newspapers, and he still doesn't know Li Yu's name.
——Of course, he doesn’t really pay attention to science. He only pays attention to where there are fat sheep waiting to be slaughtered.
John unfolded the drawings and pinned them on the blackboard. We have reached this point, all we need is 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 4 atmospheres of pressure at 0°C, and then push the piston to do work. You understand
?”
Li Yu had a mocking expression on his face and said, "I understand, you continue."
John felt that Li Yu was just mediocre. Like the people before him, he couldn't ask any questions at all when he told him the principles, so he just asked him to continue talking.
John said: "The same principle applies to steam engines. Pushing the piston makes the engine run. So you see, the energy does not use coal, but absorbs the heat of sea water. Sea water is inexhaustible. But this
This kind of research and development takes time and money. Five million taels is actually not much. The U.S. Navy spent more money at the beginning, 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 do you talk so much? Before I finished explaining the principles, money suddenly got involved. You should finish explaining the principles and plans first."
John said: "Isn't the follow-up simple? The ammonia gas pushes the piston to do work, and it will expand. When the gas expands, it will cool down, and then condense back into liquid ammonia. The cycle continues, and so on. I didn't draw enough on this drawing.
Are you in detail? Look, I have shown you all how the engine operates. I will not continue to explain the operation of the engine to you..."
Li Yu interrupted him again: "I just said you talked too much. I don't need you to explain how the engine operates. I only care about the issue of liquid ammonia and gaseous ammonia now. As for the operation of the engine later, I don't need you to continue talking.
"
Li Yuke finally understood why John was able to intimidate all the Beiyang big guys.
This guy really spent a lot of money!
When he first explained the plan to Yuan Shikai and others, he must have talked a lot about it, right down to the details of the engine's operation.
If you put it this way, 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 about engine operation. The previous perpetual motion principle
Part only accounts for 10%.
Yuan Shikai and others had never studied mechanics, so of course they thought what he said was correct.
And I don’t know where John stole the engine drawings. This thing is now a confidential design document.
How brilliant!
This is the highest level of liar.
A skilled liar will definitely not tell every lie, but often there will only be one lie among ten truths.
Ten truths or even a hundred truths gain trust, while one lie is the real core output.
This kind of routine was an extremely sophisticated deception method in Li Yu's previous life and in the 21st century. It is indeed difficult to guard against, and there are many people who fall for it accidentally.
Even many well-hidden organizations controlled by foreign forces seem to be providing public welfare assistance and have received the attention and support of many people. However, in fact, once they start to mix lies and output content, it is extremely harmful.
John asked: "Don't you understand the principle of the engine? If you don't understand, I can continue to explain it to you."
Li Yu sneered in his heart, after all, I had a bachelor's degree in mechanics and physics at university, so please stop pretending to me.
Li Yu said: "I just want to ask you a question, as long as you can answer it."
"A question?" John was no longer afraid, "That's what you say!"
Li Yu said slowly: "How can gaseous ammonia turn into liquid ammonia simply through expansion?"
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 the liquid state again."
"Very good," Li Yu said. "After talking for a long time, you finally got to 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.
"Haha! If the heat is completely isolated, how can the work be transferred to the outside? Also, there is friction, is there no friction? Moreover, the machine will heat up and absorb heat when it is running. Even if you insulate it, can it be fully enclosed? Fully enclosed
It makes no sense. And once there is air inside, the air will also absorb heat. How can you ensure that all the absorbed heat does work?"
Li Yu's series of questions directly stupefied John.
Li Yu naturally understood very well. Even in his time, the power of the most advanced internal combustion engines was only a little over 40%, almost touching the upper limit of thermal engines.
Let alone now.
John murmured: "Friction...heat insulation, this, these should all be possible."
Li Yu said with a smile: "Weren't you full of confidence just now? Why do you start talking 'should' now? Let me ask you again, do you know what the second law of thermodynamics is? If not, I can explain it to you.
speak."
John knew that he was facing a tough situation today. In fact, in this era, there are really not many people who know the second law of thermodynamics.
John said: "You have no spirit of contract! You clearly said you only asked one question, why did you ask so many!"
Li Yu crossed his hands, looked at his irritable look and smiled: "These are all small questions that are an extension of the first question."
John knew that he could not continue to confront Li Yu, so he turned to Yuan Shikai and the others and said: "Sir, I just thought about it. In fact, it can be done with 1 million taels. Let's try it first. Maybe we can make it. Maybe Beiyang
The navy can become the best navy in the world! For this purpose, even 1 million taels is not enough to try!"
Yuan Shikai and others' faces are already livid. Are you really treating us like monkeys?
Seeing that they were silent, John quickly continued bargaining: "How about 500,000 taels, oh, 50,000 taels! This is the lowest price. Let's try the head office! Just in case..."
Yuan Shikai was completely angry and said to Wang Shizhen who was standing next to him: "General Manager Wang, as the General Manager of the Military Preparation Department, you are in charge of the law enforcement department. How will you deal with bullying and concealment under military law?"
Wang Shizhen said: "The amount is huge, so he can be shot. But considering that he failed, he should also be sent 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 guard!"
Several big soldiers immediately ran in and picked up John.
John hurriedly said: "Master Yuan, please don't, even 10,000 taels will do! Hey, don't drag me! Master Yuan, I spent more than this amount to buy those drawings... let go of me!"
Yuan Shikai said angrily: "Pull him out quickly!"
John knew there was nothing he could do, so he said instead: "You can't use private law to punish me. I am an American citizen and protected by American law. The embassy will not ignore it!"
"Oh?" Yuan Shikai said, "I remember 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 knew about your visit to China this time, because you
Taking such a big risk and letting the U.S. judiciary know about it would be a serious crime."
John was completely stupid. He didn't expect to die in the hole he dug. "No! I would 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 am imprisoned in the United States!"
Yuan Shikai said coldly: "Of course not! Don't worry, our prison treatment is definitely better than yours in the United States. And you will feel better what a prison is!"
John gave up completely and began to curse in English: "Fake, you can't do this to me!"
The big-headed soldiers stuffed his mouth with cloth strips and said, "Please save me! If you are more honest, I will treat you well!"
John's face was full of despair, but he couldn't say anything, so he was dragged to the prison.
Yuan Shikai clasped his fists at Li Yu and said, "Thank you, Mr. Li Yu, for helping me get rid of a foreign liar."
Li Yu replied: "It's all right. To be honest, I hate foreign swindlers the most. You must lock him up, otherwise he will continue to cheat everywhere."
Feng Guozhang snorted coldly: "This damn foreign bastard has deceived us. He will never get out of our prison in his lifetime!"
Wu Peifu, Sun Chuanfang and others outside were completely excited:
"Let me tell you, Professor Li will definitely win!" Sun Chuanfang said proudly.
Wu Peifu also said: "I really didn't expect that John had lied to us for so long, and Professor Li had to turn him upside down in just ten minutes."
Cai Yubiao praised: "This is a great example of a great teacher. I will be such a person in the future!"
Li Jinglin rubbed his head and said, "I won't be able to become a navy captain if I do this."
Li Yu pointed to the drawing again and said: "Although this design drawing and plan are wrong in the power part, there is nothing wrong with the engine transmission plan behind it. We just need to change the power part back to coal. I think we can use it
, don’t waste it. Even if it cannot be used in naval ship engines, it can be used in many other places such as factories and mines.”
Yuan Shikai said: "I didn't know how to thank you sir, but what you said reminded me. In fact, we can't understand the drawings. Now that John is gone, only you understand. I will give you the drawings! I happened to hear 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 Yu said: "I heard from him that these drawings cost more than 10,000 taels to buy secretly. Isn't it appropriate?"
"What?" Yuan Shikai said with a smile, "Sir, do you think ten thousand taels is not enough to thank you? If you feel that sincerity is not enough, we can give you more money."
Li Yu smiled and said: "That's enough, that's enough!"
