These days, the power of 10,000 taels of silver is really extraordinary. When the disciples of the School of Physics were stimulated by this reward, they were almost crazy. They were racking their brains to develop various machinery crazily.

Yang Cong had just dealt with several blacksmith children, and before he could go back home, a few more weaver children came over and asked him to see the spinning machine they "invented".

To be honest, Yang Cong is not omniscient and omnipotent, and he really doesn't know much about the principles of spinning machines.

However, when he saw the spinning machine "invented" by these weaver children, he was still a little amused and crying.

Although this thing is not a hammer, it is similar to "inventing" a hammer.

They just added a steam engine to the turntable where they collected the yarn, and they still had to use handmade parts elsewhere.

Damn, these guys think that 10,000 taels of silver is too good?

Yang Cong was stunned for a while when he looked at the so-called "spinning machine", and then asked helplessly: "I don't know much about this spinning. Tell me, how much spinning efficiency can the spinning machine you invented improve?"

A child of a senior weaver was elected and replied carefully: "Sir, this spinning originally required two people to cooperate. One person twisted the yarn, and the other person turned the yarn to collect the yarn. If you were alone, you had to turn the yarn again. After twisting the yarn, it would be better than the two of them to work together. So, we thought about adding a steam engine to the turntable and letting it turn on by itself. In this way, one person could spin it alone, and the speed was similar to that of two people."

So that's the case. According to what he said, the efficiency has roughly doubled.

If the efficiency is already very high and doubled, it would be amazing. The problem is that the efficiency is already very low at this moment, and the steam engine has not yet been popularized. How much does it mean to double the efficiency of one or two, or dozens of companies?

Yang Cong thought about it, then looked at the loom in another corner of the room, and simply asked, "Can you demonstrate the process of spinning and weaving for me?"

Of course, there is no problem with this. These guys were very active in order to "invent" a machine and gain his recognition. Not only were the spinning machines and looms moved from home, but even the cotton yarn and yarn were moved.

Yang Congyi said he wanted to see, and they immediately picked up the ready-made cotton yarn and yarn to demonstrate.

To be honest, the spinning and weaving process at this time was indeed very backward. It was purely manpower and every process required people. There were too many things that could be improved.

Yang Cong looked carefully for a while, then thought about it for a while, then raised his hand and said, "Okay, everyone stop for a while, listen to me."

Upon hearing this, a group of children from the weaver quickly put down their work and looked over with their eyes.

Yang Cong pointed to the loom and the spinning machine, and then asked, "Didn't you find out? This loom requires dozens of yarns at a time. Why can't you spin one by one when you spin? Can't you spin dozens of or even dozens of them at a time?"

This guy has different efficiency of spinning one at a time and spinning more than ten or even dozens of them at a time. That is more than ten or even dozens of times!

Problem, spinning is not that simple, because people must twist the yarn tightly and thinly one by one. Spinning more than a dozen or even dozens of them at a time, wouldn’t there be a bunch of people standing in front of the spinning machine?

The older disciple was elected and said embarrassedly: "Sir, I'm afraid there are so many people in front of the spinning machine that spins more than a dozen or even dozens of spinning machines at a time."

When Yang Cong heard this, he fainted after a mistake. Since there is a steam engine, why do you always think about using manpower? Can you not stand so many steam engines in front of the spinning machine?

He explained patiently: "I just saw it. In fact, the process of twisting the yarn is to constantly rotate the rovings and make them thinner. This process can be replaced by a steam engine. Isn't it enough to spread as many yarn as it spun at a time?"

Now, it was the turn of the weaver children who fainted.

What a joke, is this steam engine worthless?

You should know that copper is too valuable now, and steam engines can only be made of copper. A set of steam engines costs more than 100 taels, and ten sets are more than 1,000 taels. Do you use so many steam engines, so don’t you have to pay?

Besides, even if you have money, others are not as rich as you, a spinning machine is more than 1,000 taels, which weaver can afford it!

The older weaver could only grit his teeth and said, "You are right. If you think of a way to twist the yarn, you can indeed replace it with a steam engine. The problem is that this steam engine is too expensive. If a spinning machine uses more than a dozen steam engines, no one can afford it."

You also know that you are considering the cost issue, it's good, it's good.

Yang Cong nodded slightly and said, "Well, if you use all steam engines that are thick this foot, the cost is indeed too high. The problem is that this foot-thick steam engine is used for drilling machines and grinders. Because drilling machines and grinders require a large output force, such a thick steam engine is used. If it is twisting yarn, how much force can it be required? Can such a thick steam engine be used?"

This is indeed not necessary, because the drilling machine and grinder are all iron lumps, and the force is required. If spinning, it is to twist the light yarn, and basically no force is needed.

The older Iron Dora nodded quickly and said, "No need for this. The students think that being one inch thick is enough."

When Yang Cong heard this, he couldn't help but spread his hands and said, "Will it be a bunch? How much money can a steam engine weigh more than a dozen inches? Also, the stove and the kettle can be shared completely. Since there is no need for any output force, the stove and the kettle don't need to be big. In this way, the steam engine used for a spinning machine can cost a total of several taels of silver, so who can't afford it?"

When a group of weavering children heard this, their eyes shone. If the spinning machine only needs a few taels of silver, then there will definitely be more people using it. Who can't afford to make up these taels of silver? If you can buy a spinning opportunity like this, you may be able to earn the money back in one month. You must know that such a spinning machine is equivalent to more than a dozen people working at the same time.

Problem, there is no steam engine at this moment.

Their eyes couldn't help but look at Wang Xuan on the side, because the steam engine was all made by Wang Xuan.

Seeing this, Yang Cong immediately said to Wang Xuan: "Sir, this steam engine cannot be made only one foot thick. After all, this foot thick is basically for machine tools and Fire Dragon Vehicles. If it comes to civilian use, it will not be so big. Otherwise, if you have one inch thick and more, the demand for civil use is not ordinary."

Civilian?

This term is not to be explained, it is just for the people.

When Wang Xuan heard this, he was stunned for a moment, then nodded helplessly, indicating that he knew.
