Efficiency is efficiency, at least Zhou Sijing solved the problem of nothingness and existence.

The craftsmen and clerks of the Ministry of Works were still very clever, they discovered the word resistance in the Tao Te Ching, and spent a long time testing it, selecting everything they could see in life to measure resistance.

Chen Mu doesn't know much about electricity, everything he knows has been written in general by Zhao Shizhen attached to the Tao Te Ching, if the Tao Te Ching has an understanding of the steam engine and initially comes up with practical objects, then electricity is not at all, Chen Mu can only come up with concepts.

His knowledge of electricity has been returned to the teacher, and in those concepts that he still remembers, there are resistances, positive and negative electrodes, and electric stacks, but how did all this come about, he was on the same level as the craftsmen of the Ming Dynasty - he once thought they were at the same level.

In fact, after the Ministry of Industry took over the motor manufacturing and telegraph, they were no longer at the same level, and the craftsmen knew more than Chen Mu.

The wire used by the Ministry of Industry is made of copper wire with the technology of Guangdong iron wire, the copper wire is wrapped in cotton cloth, the outer layer is oiled with asphalt, and finally the outer layer is combined with bamboo chips, leather glue and other materials.

There are too many projects they experiment with at the same time, but because of the large number of people and sufficient money and food, it is not messy, not to mention that Chen Mu has a special reward for the Ministry of Industry, and anyone who makes some useful achievements can receive a reward of hundreds or even thousands of taels, which is full of enthusiasm.

Just some time ago, there was a businessman named Cheng Dawei, who had been doing business in Jianghuai in the past, and was deceived and lost his capital in doing business, and pushed a measuring scooter of his own to the Ministry of Industry, saying that he was ingenious and created this for the government to measure the land, saying that he would receive a reward of 1,000 taels of silver.

In Zhou Sijing's mouth, the measuring scooter is indeed ingenious, the huge cart in which the wooden box shell is placed with rolled up bamboo rope, coated with oil to put dirt and easy to clean, in addition to the shell there are crosses, bamboo rulers, iron turns, drill feet and rings and other parts.

The ruler is retracted and put in and out of the plaque of the jacket, the drill foot is easy to accurately insert into the field measurement point, and the ring is easy to carry, making it easier to measure the land.

However, he was faced with a problem, that is, the ten-step tape measure made by Chen Mu had been circulated in the army, so the Ministry of Industry set the nature of his measuring scooter to improve, and only promised to give him a reward of one hundred taels; Later, in a fit of anger, Cheng Dawei simply lived in the capital, made up three sets of abacus formulas and fingerings, and took 600 taels from the Ministry of Industry before it was counted, and went south along the canal to do business.

In terms of electricity, Chen Mu really can't help, but the steam engine can.

For example, the boiler burns for a long time, and there is limescale in it.

"Distillation, heat the water, steam into the pipes, and then condense back water, the pipes should be clean. If this water is heated again, there will be less scale left inside, and the more you steam it, the cleaner it will be. ”

Society was developing, and many later words were already used in the Ming Dynasty, such as distillation, which also had the same meaning, describing the process of transpiration, but without distilled water.

In this era, the word referring to the distillation process was called steaming, and it was often used to make shochu and essential oils.

Zhou Sijing had an extraordinary interest in the steam engine, and he asked in surprise: "Water without roots?" ”

Chen Mu thought about it, it was indeed about the same, he smiled: "Yes, rootless water is groundwater that evaporates into the sky, and then condenses back to the ground when it is cold, and this is what we distilled water means, it's just manpower." ”

"Gong Chen is really a steamer, wait a minute!"

Zhou Sijing's eyes lit up when Chen Mu said it, especially after he designed a new steamer that seemed to be useless, Chen Mu still encouraged it to improve, and his good impression of Chen Mu in his heart was simply too high, I don't know what Chen Mu's distilled water reminded him of, and suddenly arched his hand and rushed to the hastily built wooden house in the distance.

Walking through the power generation test site with black smoke everywhere, Zhou Sijing came back a little embarrassed and said to Chen Mu: "Chen Gong, please follow me into the burrow, the students have many doubts!" ”

The age difference between the two made Chen Mu feel embarrassed by such a title, but he didn't refute Zhou Sijing's face, to be honest, he saw Zhou Sijing, who was fanatical about novel knowledge, but really had a sense of joy that could only be hidden in his heart as a teacher.

Zhou Sijing's house is not furnished, because of the hasty construction, there is not even a yard, just a small house separated by a screen, but the inside is clean, the wooden planks on the ground are flat, except for the bed in the inner room and the table in the outer hall, what catches the eye is two cabinets, full of books.

There is a very thick drawing neatly placed on the table, he also likes to use the craftsman's charcoal, and the charcoal he uses is the same as Chen Mu's - a specialty of Xiangshan Qianhu, the rod is cut with all kinds of wood, oiled processing, and some will carve out patterns, the front is detachable bamboo glued charcoal head, relying on the elastic tenon of the bamboo piece on the pen barrel, and it can be disassembled after use.

This kind of thing called Xiangshan pen is sold separately from the pen head, the production is simple, and it is loved by craftsmen and painters.

"This is a diagram of the steaming mechanism made by the students." Zhou Sijing smiled and launched the drawing, and then picked up another one and said: "This is the composition of Nanyang Chen Gongji, there are many questions that I don't understand, and I ask Chen Gong to solve my doubts." ”

Chen Rooster?

The name of this dish sounds very Cantonese.

Chen Mu chuckled, followed Zhou Sijing's fingers, and listened to him: "The students have dismantled the two steamers, the parts of the Nanyang steaming mechanism are tightly fitted, and the new speed control valve and piston made by the Ministry of Industry are not fine enough, why is this?" ”

"Because most of the steaming machines in Nanyang are not cast, they are made by hand, and they can be compared one by one, and a lot of waste can be used to create a set of components. Moreover, the Nanyang-made parts are not fine, and there are air leaks, but there are few. Chen Mu shook his head and said: "Shortcomings are inevitable, just like when electricity is not stable, people are willing to use electric lights that flicker occasionally. ”

"There is a big difference between having and not, first find the shortcomings, and then slowly improve, where there is a problem, change it, if you can't change it, just think about why you can't change it."

"The significance of the steam engine is not only that it can be used in all kinds of production such as making electricity, but also that our demand for it will force all kinds of technological progress."

In fact, he doesn't know much about this, and he has no way to improve the existing shortcomings, but with the Ministry of Industry, these craftsmen who specialize in studying tools and projects invest more and more energy, which makes Chen Mu feel more and more that the emergence of the steam engine is like letting Daming invest in overseas hegemony, which is a cause that is plucked and raised, hard work but very rewarding.

The advent of a steam engine, a small gadget, can involve almost all walks of life.

"Our lathes are not accurate enough, so we have to find a way to make it enough; Our material is too heavy, the heat dissipation is too fast, we have to find a way to make it light, so that it can retain heat, all development comes from demand, without demand, people are more willing to lie at home and drink ice water. ”

The reason why he is reasonable is because Chen Mu doesn't want the old fan brother to see through his true face of not learning and not knowing.

"When the demand comes, people will think, and when they think, there will be extraordinary creativity, and technology will naturally advance."

As he spoke, Chen Mu pointed to Zhou Sijing's steam engine and said: "If you replace the wind wheel with a harder and lighter material, and guide the direction of the steam to push the fan blades many times, the wooden car equipped with the steamer is larger, and replace it with a flat car with two wheels in the front and two wheels in the back, and the front wheel guides the direction and the rear wheel is connected with the wind wheel with gears...... If the car is light enough and the steamer is light enough, will it be able to run? ”
