Xinshun 1730

Chapter 321

The best group of craftsmen gathered in the lecture hall. Some of these people have built boring machines, some have dismantled Newcomen steam engines, and there are more than a dozen semi-college students selected from the group of orphans who understand science but do not know technology. Children apprentice.

On the blackboard, Liu Yu was talking about a very important issue, but it might sound like nonsense to these people.

"When water is boiled, it turns into water vapor, which absorbs heat; when water vapor turns into water, it has to release heat...The heat is all burned by coal. Just like a bucket of water, whether you put it in a teapot or soak it in clothes , the total amount is certain.”

These seem to be very intuitive knowledge in the eyes of craftsmen.Even though much of the science since has been counter-intuitive, much of the science at this time is intuitive.

Liu Yu talked eloquently about heat release, heat absorption, and coal burning, and finally talked about improving the steam engine.

Theoretically, it is not difficult. If you have learned the mechanical principle, the crank linkage system is not a problem. Anyway, Dashun does not have a patent system, and there is no need to bypass the patent and design a planetary gear system separately like Watt.

He talked a lot, and the people below basically understood it. The overall problem is to improve the steam engine that pumps water in the dock that Weihai already has, and many of them can imitate, and separate the condensation. The appliance, finished only moving up and down until it can be cranked, burns less coal with more power.

As for how strong the strength is, strength is one issue, and power is another issue. Liu Yu didn't say it so politely, but made a joke.

"If you want to talk about how strong it is, it is said in the storytelling that Xue Rengui ate the noodle cakes of the Nine Heavens Xuannv Empress, and gained the power of one dragon, two tigers and nine oxen. We dare not imagine how great the power of the dragon and tiger is. But say This is the strength of the cow. I said that one day we will test how much work this cow can do."

"Find a deep well, build a pulley, get a 1000-jin iron lump, and let the cow pull it on flat ground. Take a pocket watch and see how far it can be pulled in one minute. This is considered the power of an ox. When you come up with an improved steam engine, if you can achieve the strength of two oxen, it will be considered a success. If you can achieve the strength of three oxen or five oxen, then there will be another reward."

"How big is the power of a cow, you can try it yourself in a few days."

After speaking, he simply drew a fixed pulley pattern, and a strange animal with two horns protruding out in front of it was regarded as a cow.

Straightforward and clear at a glance, it is more intuitive to define power than to rigidly specify such things as cattle, acceleration, speed, and mass.

Those orphans who survived the catastrophe learned the difference between power and force, and they have their own system of conversion units, and these are all their after-school exercises, so they can easily solve the power converted from high potential energy.

It's just that those craftsmen don't know how to count, but when they heard the power of one dragon, two tigers and nine oxen, they all laughed.

Hearing that Liu Yu's request is not high, that is, two or three cattle's strength is enough, some craftsmen thought to themselves, this is easier than a boring machine.

There is also a boring machine, the cylinder can also be dug, the crank structure is also available, and the self-feedback regulator is also copied. Several people looked at the pictures on the blackboard, patted their chests and said: "It can be done in two years at most. But, my lord , come up with this thing, isn’t it just used to carry water?”

Liu Yu smiled and said: "Of course not. Can't you use water to drain the business? And you don't need to have water. Some horse-drawn ones, such as grinding discs and mills, can also be used. Wrought iron, smashing armor, Even driving this boring machine, can’t it be used?”

"You make it first, and then think about where to use it in the future. Anyway, it's my money."

When everyone thought about it, they felt the same way, anyway, they would give Liu Yu money in real money.Even if it is made to play, no one can control it.

But some people immediately thought of their previous industry, and thought that if this thing could be made, it might save a lot of trouble.

For example, the salt well in Sichuan, with this thing, wouldn't it be necessary to raise so many cows pulling the potter's wheel?This thing works [-] hours a day without a break, and the cow can't work all day, even if it doesn't sleep, it has to ruminate.

Different industries have thought of different uses, and Liu Yu also has plans in mind.

Anyway, it can't be used in the textile industry first, regardless of the impact on the textile industry, it must also be considered that the steam engine is a power source, and there is no large-scale machine suitable for power machinery yet.

It is estimated that the hydraulic spinning machine in the UK is also fast. After finishing the war in the Netherlands, I will find a chance to go to Europe and evaluate what can be directly "used for doctrine". I copy it if I can.

The United Kingdom's Manchester Act has been implemented, which is both a challenge and an opportunity for Dashun's cotton textile industry.

Without this bill, Dashun would not be able to copy, because Dashun's mainstream clothing material is not wool, and wool imitation technology and wool-cotton blending technology are different from pure cotton textile technology.

This may take a while. If the steam engine is developed, it must be used in some emerging industries first.

Most of the emerging industries are controlled by him, and they are not small workshops, which will not arouse opposition from peers.

Grinding glass, mining, wrought iron, crushing ore, sawing wood, machinery... these industries are all useful.

Unlike Britain, which followed the economic law of light industry first and then heavy industry, Liu Yu wanted to use the power of the imperial court to promote rather than develop spontaneously, so he must first heavy industry.

The iron mines and coal mines in Liaodong, and even the coal mines in Tangshan, are all things that have grown from scratch, and there is not much opposition to new things.

Different from the situation in the Manchu Qing Dynasty, when the Manchu Qing came to the Boxers, it was not necessarily anti-science, but more like a kind of populism—foreigners were bad, we didn’t use the things made by foreigners, and the things made by foreigners were not so good. If you can't reach the black spot, then look for it from superstition.

It is more of a populism with a sense of loss after the fall of China.

It's a strange emotion.

If you made this thing first, then it means that this thing is really good, and foreigners are not really barbaric; if others made it first and bullied you badly, then it means this thing is not good, even if it works, there must be something. Bad things, there must be good things about things from our ancestors.

Liu Yu felt this mentality very clearly.For many traditional industries, the more useful they are, the more open and inclusive they are; the more backward and useless they are, the more closed and repulsive they are.

Since he made it first on his side, he didn't worry about it.

Waiting for this group of orphans taught by myself to practice for a few years, with a foundation in science and practical skills, they can be counted on to build steam locomotives. This is the thing that most impresses the emperor’s support—the Grand Canal that does not need water , It is convenient to deploy troops, facilitate rule, facilitate repression, facilitate centralization of power, facilitate preventing the emergence of local forces, etc., the emperor must be happy to see it.

Conversely, if it is engaged in the textile industry, the force basis for foreign dumping is not enough, so it can only roll inward.

Regardless of quality or price, Dashun's cloth has a huge advantage in the international market, but it is useless. In the real world, there is no truly free market that is not controlled by the government.

To do this is actually to enrich the profits scattered in the hands of various small handicraftsmen into the steam factory.If you want to rely on this method to enrich funds to build coal and iron complexes and build railways, Liu Yu feels that it is better to engage in trade and government-run export trade to get money faster, have less impact, and the emperor is easier to support.

He didn't even want to make money quickly through trade, so naturally he didn't want to go this way.Even if they leave, they have to establish a firm foothold in India and fully open the door to Japan before they can engage in the textile industry. The order of priority must not be mistaken.

The only thing to worry about at this time is time.The craftsmen were full of confidence and believed that within two years, the improved steam engine he requested would definitely be produced.

With the steam-powered blower driven by this, you can try new iron and steel smelting methods, which is all right.

Is this group of orphans who have high hopes cultivated by themselves, can they use their theoretical knowledge and technical experience to produce an experimental steam locomotive within ten years after the success of the steam engine research?
After the meeting ended, Liu Yu left the dozen or so half-grown children behind.Seven or eight years have passed since the great famine, and these children have also studied in a closed environment like Liugong Island for seven or eight years.

Although during these seven or eight years, on average, Liu Yu could only spare four or five days a month to give lectures to this group of children, but he still instilled enough theoretical knowledge that transcended the times.

The oldest child is already eighteen, and from those children who were on the verge of starvation to death, they have become young men and big girls.

"teacher."

Calling in unison, Liu Yu told them all to sit down and talk about the train.

They have all studied a text written by Liu Yu, or "science fiction", titled "Appearance in 50 Years".

The science fiction written by the "Prophet" is not science fiction, but a divinely accurate prophecy. Although these children have never seen a train, it does not prevent them from knowing about trains.

They not only know trains, but also know that there is nitrogen in the air, and if it can be enriched, it can be used as fertilizer; that steel and iron are only different in carbon content; that people get sick because of bacteria; Electricity is the same as electricity.

Just like the children of later generations, even if they are only ten years old, even if they have never flown into space, they still firmly believe that the earth is round.

Just like the children of later generations, even if they have never seen rhizobia, even if they have never touched chemical fertilizers in their entire lives, they still believe in the root nodules of the elders under soybeans, and are deeply impressed by the three words nitrogen, phosphorus and potassium.

The closed environment and arbitrary teaching materials gave these children a similar worldview and cognition to Liu Yu.

Liu Yu rarely quoted some poems to encourage these children.

"The old ancestors have a good saying, there are tens of thousands of mansions, and the people in the world are happy. This is what you will do in the future. If there is a train, the famine in Jiaodong will be able to adjust the south of the Yangtze River. Rice; if there is a famine in Shaanxi, Gansu, and Sichuan, grain from Sichuan can be used. People always need clothing, food, housing, and transportation, and a big shelter for the poor and happy people in the world is living. If you can make a train, you can travel and eat.”

"You have all been hungry, and you know what it feels like to be hungry. Now I am almost thirty, and the world I wrote 50 years later will be more than 50 in 70 years. People say that when people arrive Seventy years old, I hope that when I live to that time, I can see the world in that article come true.”

"Do well, I am optimistic about you. You have learned what the world is like, but the key to the problem is not to explain the world, but to change the world."
