In this year, the power of 10,000 taels of silver is really extraordinary, and the disciples of the School of Physics are stimulated by this reward, and they are all going crazy, and they are all racking their brains and developing various machines frantically.

Yang Cong had just finished dealing with a few blacksmith children, and before he could return home, a few more weavers' children took the initiative to come over and beg him to see the spinning machine they had "invented".

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

However, when he saw the spinning machine "invented" by these weavers, he still couldn't laugh or cry.

It's not a hammer, but it's like "inventing" a hammer.

They added a steam engine to the turntable for collecting yarn, and in other places, they still had to use manual work.

Nima, these guys think 10,000 taels of silver is too good, right?

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

A weaver of the older grade was elected and replied cautiously: "My lord, this spinning originally required the cooperation of two people, one person twisted the yarn, and one person turned the turntable to collect the yarn. So, we thought about adding a steam engine to the turntable and letting it spin on its own, so that one person could spin the yarn alone, and the speed was about the same as that of two people. “

It turns out that this is the case, according to him, this efficiency is about doubled.

If the efficiency is already very high, and it is doubled, it will be terrible, the problem is that the efficiency is very low at this time, and the steam engine has not yet been popularized, how much is the point of doubling the efficiency of a single family or two or a dozen or dozens of companies?

Yang Cong thought for a while, looked at the loom in another corner of the room, and simply asked, "Can you show me the process of spinning and weaving?" ”

Naturally, this is no problem, these guys have come out to "invent" a machine to get his approval, which is very positive, not only spinning machines and looms have been moved from home, but even cotton yarn and yarn have been moved.

As soon as Yang Cong said that he wanted to see it, they should even pick up ready-made cotton yarn and yarn and demonstrate.

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

Yang Cong looked at it carefully for a while, pondered it carefully for a while, and then raised his hand and said, "Okay, let's stop for a while and listen to me." ”

When the weavers heard this, they hurriedly put down the work in their hands and looked at it with a blank eye.

Yang Cong pointed to the loom and then to the spinning machine, and then asked: "Didn't you find that this loom has to enter dozens of yarns at a time, why can you only spin one by one when you spin, can't you spin a dozen or even dozens at a time?" ”

This guy, the efficiency of spinning one at a time is not the same as spinning a dozen or even dozens of sticks at a time, which is more than ten times or even dozens of times!

The problem is that spinning is not so simple, because people have to twist the yarn tightly and finely one by one, spinning a dozen or even dozens at a time, and there are not a bunch of people standing in front of the spinning machine!

It was still the older disciple who was elected out, and said embarrassedly: "My lord, I'm afraid there are so many people standing in front of a dozen or even dozens of spinning machines at a time." ”

When Yang Cong heard this, he fainted at the wrong point, since he has a steam engine, why do he always think about using manpower, there are so many people standing in front of the spinning machine, can there still be so many steam engines?

He patiently explained: "I just watched, in fact, the process of twisting the yarn is to constantly rotate the roving to make it thinner, this process can be completely replaced by a steam engine, how many yarns can be spun at a time, how many steam engines can be placed?" ”

Now, it was the turn of the weavers' children to faint.

What are you kidding, doesn't this steam engine cost money?

You must know that copper is always valuable at this time, and the steam engine can only be made of copper, a set of steam engines costs more than 100 taels, and 10 sets are more than 1,000 taels.

Besides, even if you have money, others don't have money like you, a spinning machine is more than a thousand taels, which weaver can use it!

The older weaver could only bite the bullet and say: "My lord is right, if you think of a way to twist the yarn, you can indeed use a steam engine to replace it, the problem is that this steam engine is too expensive, if a spinning machine uses a dozen steam engines, no one can afford to use it." ”

You also know that you think about the cost, yes, yes.

Yang Cong nodded slightly and said: "Well, if all the steam engines of this foot thick are used, the cost is indeed too high, and the problem is that the steam engine of this foot thick is used for drilling machines and grinding machines, because both drilling machines and grinding machines need a lot of output strength, so such a thick steam engine is used." If it is twisting, how much force can be needed, and can you use such a thick steam engine? ”

This is really not needed, because the drilling machine and the grinding machine are processing iron lumps, which requires a lot of strength, and the spinning is to twist the light yarn, which basically does not require any strength.

The older weaver himself nodded hurriedly and said, "This is not necessary, the student thinks that it is enough to have an inch thick." ”

When Yang Cong heard this, he couldn't help but spread his hands and said: "Isn't that over, how much is a dozen one-inch thick steam engines worth?" Also, the stove and kettle can be shared, and since you don't need any output strength, the stove and kettle don't need to be that big. In this way, a steam engine for a spinning machine will not cost a few taels of silver in total, and who will not be able to afford it? ”

If this spinning machine only needs a few taels of silver, then there must be more people, who can't afford to make up these few taels of silver, if you can buy a spinning opportunity like this, I'm afraid you can earn back this silver in a month, you know, such a spinning machine is equivalent to more than ten people working at the same time.

Problem, there is no steam engine of about an inch at this time.

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

Seeing this, Yang Cong immediately said to Wang: "Sir, this steam engine can't just be made of one foot thick, after all, this foot thick is basically used for machine tools and fire dragon cars, and when it comes to civilian use, it can't be used at all." Otherwise, let's go out of the whole inch thick and make more, the demand for this civilian is not ordinarily large. ”

Civil?

This term doesn't need to be explained, it's just for the common people.

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

He has always felt that the steam engine can only be used in a few places such as their physics college, the Ministry of Engineering, and the official kiln, where did he think that this thing would enter thousands of households and become something that ordinary people can use.
