Li Zhen laughed: "Anything, don't look at the surface." ”

"What's going on? Please tell me, Master Li. Jia Liping scratched his ears and cheeks anxiously. He couldn't figure it out, why did others save money from him and didn't charge storage fees, so what could he rely on to make a profit?

Li Zhen said: "Our money bank is not just about helping others keep money. We also lend money out. This kind of loan is our main profit model. And where does the money come from to lend money to others? ”

Jia Liping slapped his thigh suddenly: "The money you lend to others is still someone else's money." ”

Li Zhen smiled and said, "You have understood." That's right, the merchants kept their money with us for convenience. According to probability, it is impossible for everyone to withdraw all their money at the same time. In this way, everyone's money is with us, but we can take it out and use it, which is a cyclical process. And those businessmen who need loans, the money they borrow is actually coming from 'someone else's money'. ”

"Empty gloves white wolf......"

"What nonsense is telling the truth."

Li Zhen scolded with a smile: "So in terms of relationship, we have formed such a connection: the person who saves money with us has theoretically become the person who lends us all the money." And we use the borrowed money, plus the interest, to lend it to those who need it. Of course, the people who deposit money with us, not only do they not charge, we also give them money. If the person who keeps money with us gives them an interest rate of 1/1000 a month, that is, if he deposits 1,000 grams of gold with us, and he takes it out after a month, he will get 1,001 grams of gold.

And those who borrow money from us, we can give them one percent interest. Borrow 1,000 grams of gold, and pay back 1,010 grams after a month. And what we earn is this spread, and this spread is nine thousandths. That is, if the left hand is reversed from the right hand, nine thousandths of the profit will fall into the pocket. ”

Jia Liping counted with his fingers, the more he calculated, the more excited he became, and asked: "But in this case, this income is a little too small, right?" It's only nine out of a thousand. ”

Li Zhen slapped him on the head fiercely: "Still young? Don't count the single digits, I'm just giving you an example. Do you know how many capitalists there are in the whole of Dongzhou? Do you know how many people there are in Dongzhou? What if everyone in the whole Dongzhou kept their money with us? What if all the people of Kyushu kept their money with us? ”

Li Zhen laughed and said, "Moreover, after we have money, we have more ways to make profits." Then open some companies and open them in the subordinate offices of the money bank. The company then uses the money in the money bank to invest in something that guarantees a steady profit and no loss. Isn't this another form of money to make money? ”

"And when our 'vouchers' mature, won't the entire market be completely circulated? Isn't this voucher a new dollar? Isn't the work of making money left to us? Even if a new dynasty is established, the whole country will still have to use the money we have created. What is the richest country? The rich rival country is that even the country of the rich has to be attached to you. ”

Jia Liping jumped up excitedly: "I understand, I understand Master Li." I see, you're really thinking about it, I didn't even think you had such a purpose in storing gold. Master Li, where did you get all this whimsy? ”

Li Zhen smiled: "I forget who told me, it seems that 10,000 years ago there was an institution called a bank. ”

"Who told you?"

Li Zhen's expression suddenly drifted away: "Forgot ......"

Jia Liping left excitedly, and another student hurriedly ran over: "Master 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, united 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 entire Kyushu Academy of Sciences. This Ma Jianbin is the newly appointed dean and the first batch of veterans of the Academy of Physics. took Qin Enze's place, in fact, they had been looking forward to Qin Enze's return, but they also knew that they should not be able to come back.

Unexpectedly, the synchronous motor was obviously researched by the Institute of Electromagnetism. But in the end, in fact, it is the cooperation between the Aviation Institute and the Mechanical Institute that has pushed it to maturity, and there is also a shadow of the participation of the Institute of Electromagnetism, but it is relatively rare.

Today is the day of the synchronous motor demonstration, and the entire physics institute has come out. The Aviation Institute and the Machinery Institute were beaming with joy and were incomparably happy. However, all the staff of the electromagnetic institute had gloomy faces, and they didn't speak, just clubbing. Looking at the people in the two houses, it was as if they had a grudge against their father. There is no way, the main focus of the School of Electromagnetism is now on the asynchronous AC motor, and there is no time to manage the synchronous motor, but I didn't expect other institutes to take advantage of the loophole.

Li Zhen sat on the chair, looked at the iron lump about the size of two fists in the field with interest, and said with a smile: "Synchronous motor? ”

Liu Jinghong said excitedly: "Well, since the synchronous motor appeared in the science and technology award, we have fallen into research. If the synchronous motor can be installed on the airship, this completes the reality that the airship can be freely and artificially controlled. Steam engines, steam turbines, can't be carried into the air because they are too heavy and require a lot of coal, heavier. Not only will it not be able to propel the airship forward, but it will become superfluous. But synchronous motors are different, only this small motor, and the battery are all you need. The weight is relatively much, much lighter. ”

Li Zhen smiled: "Let's test it." ”

Someone immediately connected the direct current to the motor.

'Buzz' on the spot, the rotor exposed outside the iron bump began to spin violently, and it 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, or even dozens of times, that of the steam turbine, right?

Liu Jinghong smiled proudly: "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 large.

The 'hum' rotor immediately emitted a high-speed rotation again. 'Huhuhu' has a gentle wind sound, through the propeller, more intuitive to see its speed, indeed the speed is extremely high.

But Li Zhen always looked smiling, and he still didn't express his opinion until after the demonstration.

Everyone turned their heads to look at Li Zhen with some uneasiness: "Master Li...... Do you think it is realistic to develop the synchronous motor into the forward driving force of the airship? ”

"Unrealistic." Without any hesitation, Li Zhen shook his head very decisively.

There was an uproar.

I have never seen Li Zhen so decisive.

No, it's supposed to be very realistic, why does he have to say it's unrealistic?

The idea of an airship has now become a common topic of the Institute of Physics, and they dream so much of conquering the blue sky. Let the airship go to the sky, and it did. But moving forward...... It has become a common problem in the Department of Physics in Kyushu.

This time, the maturity of the synchronous motor gave them a little hope. But unexpectedly, Li Zhen decisively denied it.
