Rising: Ten Thousand Years Chapter 190: : Motor
Li Zhen laughed loudly: "Don't look at the surface of anything."
"What's going on? Master Li, please tell me." Jia Liping anxiously scratched his head. He couldn't figure it out, why other people deposit money with him without charging storage fees, and how can they make a profit?
Li Zhen said: "Our money bank is not just helping others keep money. We also lend out. This kind of loan is our main profit model. And where does the money for lending to others come from?"
Jia Liping suddenly slapped his thigh: "The money lent to others is still other people's money."
Li Zhen said with a smile: "You have realized it. That's right, the merchants have deposited money with us for convenience. According to probability, it is impossible for everyone to withdraw all the money at the same time. In this way, everyone’s money is with us, but we can use it. This is a circular flow process. Those businessmen who need loans actually borrow money from 'others' Out of money."
"White wolf with empty gloves..."
"What nonsense is telling the truth."
Li Zhen scolded with a smile: "So in terms of relationship, we have formed such a connection: people who save money with us, in theory, become the ones who lend us all the money. And we use the borrowed The money, and then calculate the interest and lend it to people who need money. Of course, people who deposit money with us will not only charge nothing, but we will also give them money. If people who save money with us, we will count it as a thousand a month for them. 1/1 of the interest, that is to say, if he deposits 1000 grams of gold with us, he will get 1001 grams of gold after taking it out a month later.
As for those who borrow money from us, we can give them 1% interest. If you borrow 1000 grams of gold, you will have to repay 1010 grams after one month. And what we earn is this spread, which is nine thousandths. In other words, if the left hand is turned to the right hand, nine thousandths of the profit will fall into the pocket. "
Jia Liping counted with his fingers, and the more he calculated, the more excited he became, and he asked: "But in this case, the profit is a bit too small, right? It's only nine out of a thousand."
Li Zhen slapped him **** the head: "Still young? Don't count single digits, I'm just giving you an example. Do you know how many capitalists there are in Dongzhou? Do you know how many ordinary people there are in Dongzhou? What if everyone in Dongzhou deposits their money with us? What if everyone in Kyushu deposits their money with us?"
Li Zhen laughed, and said again: "Besides, after we have money, we have more ways to make money. We will open some companies and set up subsidiaries in the money bank. This company will go to the money bank to invest in something that is guaranteed to make a steady profit. Doesn’t this make money make money again?”
"And when our 'voucher' matures, won't the entire market be completely circulated? Wouldn't this voucher become a new currency? Isn't the work of making money also left in our hands? Even if a new dynasty is established at that time, the whole country still needs to use the money we created. What is a country that is so rich that it can't be rivaled? A country that is so rich that it is so rich that even the country will be attached to you."
Jia Liping jumped up excitedly: "I understand, I understand Master Li. I understand, you are really far-sighted, I didn't expect you to store gold for such a purpose. Master Li, you Where did the whimsy come from?"
Li Zhen smiled and said: "I forgot who told me, it seems that there was an institution called a bank 10,000 years ago."
"Who told you that?"
Li Zhen's expression suddenly became ethereal: "Forgot..."
Jia Liping left excitedly, and another student hurried over: "Mr. Li, I also have a question to ask."
“…”
The next day, the Kyushu Academy of Sciences made another big move.
Liu Jinghong, who returned to school, teamed up with Ma Jianbin, the current interim dean of the Institute of Mechanical Power, and finally developed a synchronous motor with quite mature technology today.
The matter of Qin Enze's treason is now avoided by everyone in the Kyushu Academy of Sciences. This Ma Jianbin is the newly appointed dean and one of the earliest veterans of the Academy of Physics. Taking Qin Enze's place, in fact, they have been looking forward to Qin Enze's return, but they all know that they probably won't come back.
Unexpectedly, the synchronous motor was obviously developed by the Institute of Electromagnetics. But in the end, it was actually the cooperation between the Academy of Aeronautics and the Academy of Mechanical Engineering that pushed it to maturity. There are also shadows of the participation of the Electromagnetic Academy, but there are relatively few.
Today is the day to demonstrate synchronous motors, and the entire Institute of Physics came out. The Academy of Aviation and the Academy of Mechanics were beaming, and they were incomparably happy. However, all the staff in the Electromagnetic Institute had a gloomy face, they didn't speak, and just stood there like that. Looking at the people in the two courtyards, it seemed that they had revenge for killing their father. There is no way, the School of Electromagnetics is now focusing on asynchronous AC motors, and has no time to deal with synchronous motors. I didn't expect to let other schools take advantage of the loopholes.
Sitting on a chair, Li Zhen looked at an iron bump about the size of two fists with great interest, and said with a smile: "Synchronous motor?"
Liu Jinghong said excitedly: "Well, since the synchronous motor was shown at the Science and Technology Awards, we have fallen into research. If the synchronous motor can be added to the airship, this will complete the airship's ability to move freely. Yes, the reality of human manipulation. Steam engines and steam turbines cannot be brought into the air, because they are too heavy and require a lot of coal, which is even heavier. Not only cannot propel the airship forward, but it will become redundant. But synchronous motors are not It’s the same, you only need this small motor and a battery. The weight is much, much lighter.”
Li Zhen smiled: "Let's try it out."
Someone immediately connected the DC power to the motor.
On the spot, the rotor exposed from the iron bumps began to spin violently, which seemed to be quite efficient.
Everyone was in an uproar. They didn't expect that these two fist-sized things could have such a high speed. This speed is more than ten times higher than that of a steam turbine, or even dozens of times, right?
Liu Jinghong smiled triumphantly: "In order to let everyone feel intuitively, now connect the propeller to this rotor."
Someone immediately installed a small fan blade. The total length of the fan blade is only a dozen centimeters long, not too big.
The 'hum' rotor immediately spun at a high speed again. There was a soft sound of wind coming from 'huhuhu', and through the propeller, I could see its speed more intuitively, it was indeed extremely high ~IndoMTL.com~ But Li Zhen kept smiling until after the demonstration , and still do not comment.
Everyone turned their heads to look at Li Zhen with some unease: "Mr. Li... Do you think it is realistic to develop the synchronous motor into the driving force of the airship?"
"Unrealistic." Without any hesitation, Li Zhen shook his head decisively.
Everyone was in an uproar.
I have never seen Li Zhen be so decisive.
No, it should be very realistic, why does he insist on saying it is unrealistic?
The idea of the airship has now completely become a common topic of the Academy of Physics, they are too dreamy to conquer the blue sky. Let the airship go to the sky, did it. But moving forward... has become a common problem in the Kyushu Physics Department.
This time the maturity of synchronous motors gave them a little hope. But unexpectedly, Li Zhen decisively denied it. ) Download Free Reader!!
