Chapter 575
Efficiency is all about efficiency, at least Zhou Sijing has solved the problem of nothing and having.

The craftsmen and officials of the Ministry of Industry are still very clever. They discovered the word resistance in the Tao Te Ching, and spent a long time in the test, choosing all the objects that can be seen in life to measure the resistance.

Chen Mu doesn’t know much about electricity, and everything he knows has been written in general by Zhao Shizhen in the Tao Te Ching. If it is said that the Tao Te Ching has some understanding of the steam engine and initially produced practical objects, then there is no electricity at all. Chen Mu can take it. Only concepts come out.

All his knowledge about electricity has been returned to the teacher. Among the concepts he still remembers, there are resistors, positive and negative poles, and stacks, but how did all this come about? He is at the same level as the craftsmen of the Ming Dynasty —He once thought they were on 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. The craftsmen knew more than Chen Mu.

The electric wires used by the Ministry of Industry are made of copper wires using the technology of Guangdong iron-drawn wires. Copper wires are wrapped with cotton cloth, the outer layer is coated with oil and asphalt, and finally the outer layer is laminated with bamboo chips, leather glue, etc. What to choose? By experiment.

They experimented with too many projects at the same time, but because of the large number of people and sufficient money and food, it is not messy. What's more, Chen Mu specially offered rewards to the Ministry of Industry. The reward of a thousand taels is full of motivation.

Just a while ago, there was a merchant named Cheng Dawei who had been doing business in Jianghuai in the past. He was deceived into losing his capital when he did business. He pushed his own measuring scooter to the Ministry of Industry and said that he had created this Come to the government to measure the land, and say that you will receive 1000 taels of silver as a reward.

In Zhou Sijing's mouth, the measuring walking cart is really ingenious. The wooden box shell of the huge trolley is placed with rolled bamboo ropes, which are painted with clear oil to prevent dirt and easy to clean. Made of swivel, drill feet and rings and other components.

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

However, he encountered a problem, that is, the ten-step tape measure made by Chen Mu had been circulated in the army. Therefore, the Ministry of Industry defined the nature of his measuring step as an improvement, and only promised him a reward of 100 taels; Living in Beijing as a guest, he compiled three sets of abacus formulas and fingerings, and took 600 taels from the Ministry of Industry before giving up and going 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 has built-in scale.

"Distillation, heat the water, steam enters the pipeline, and then condenses back to the water, the pipeline must be clean. This kind of water is heated again, and there will be less scale left in it. The more steaming, the more steaming, the cleaner it will be. "

With the development of society, many later words already existed in the Ming Dynasty, such as distillation, which has the same meaning and describes the process of transpiration, but there is no distilled water.

The term referring to the distillation process in this era is called steaming, and it is often used for the production of shochu, essential oils, etc.

Zhou Sijing has an extraordinary interest in steam engines, and he asked in surprise: "Water without roots?"

Chen Mu thought for a while, and it was indeed the same. He smiled and said, "Yes, rootless water means that groundwater evaporates and rises to the sky, and then condenses and falls back to the ground when it is cold. The same is true for our distilled water, but only with human power."

"Chen Gong is indeed a steamer master, wait a moment!"

Zhou Sijing's eyes were brightened by Chen Mu's words, especially after he designed a new type of steamer that seemed useless, Chen Mu still encouraged him to improve, and his affection for Chen Mu was so high that he couldn't be more fond of him. Mu's distilled water reminded him of something, and suddenly he arched his hands and rushed towards the hastily built wooden house in the distance.

Passing through the power generation test field with black smoke everywhere, Zhou Sijing ran half way and came back in embarrassment, and said to Chen Mu: "Mr. Chen, please follow me into the shabby room. The students have many doubts!"

The age difference between the two made Chen Mu feel embarrassed by such a title, but he did not have the face to refute Zhou Sijing. To be honest, when he saw Zhou Sijing, who was crazy about novel knowledge, he really had a kind of teacher who could only be hidden in his heart. sense of joy.

There are not many furnishings in Zhou Sijing's house. Because of the sloppy construction, there is not even a yard. It is just a hut separated by a screen, but the inside is tidied up and the wooden boards are laid on the floor, except for the bed in the inner room and the table in the outer hall. , the eye-catching is the two cabinets, filled with books.

There are thick drawings neatly placed on the table. He also likes to use craftsman’s charcoal pens, and the charcoal pens he uses are the same as those used by Chen Mu—a special product of Qianhu in Xiangshan. The rods are cut from various kinds of wood. It is oiled and processed, and some of them can also be carved with patterns. The front is equipped with a detachable bamboo slice glued charcoal head, and the bamboo slice is elastically mortised and tenoned on the pen holder, which can be disassembled after use.

This kind of thing called Xiangshan pen is sold separately from the pen holder and the nib. It is easy to make and is loved by craftsmen and painters. At present, many guards in Guangdong are making it.

"This is the drawing of steaming mechanism made by the students." Zhou Sijing smiled and pushed out the drawing, then picked up another one and said: "This is the composition drawing of Nanyang Chen Gongji, there are many questions that I don't understand, please ask Chen Gong to explain. "

Chen cock?
The name of this dish sounds very Cantonese.

Chen Mu smiled lightly, followed Zhou Sijing's fingers with his eyes, and heard him say: "The students have dismantled two steamers, and the components of the Nanyang steamer are tightly fitted. ?”

"Because most of the steamer structures in Nanyang are not cast, they are made by hand, and compared one by one, a set of components can only be made with a lot of waste. Moreover, the parts made in Nanyang are not fine, and there are also air leaks, but there are few." Chen Mu shook his head and said. : "Shortcomings are inevitable, just like when the electricity is not stable, people are willing to use the occasional flashing lights."

"There is a big difference between yes and no. First find the shortcomings, and then slowly improve them. If there are any problems, fix them. If you can't fix them, think about why you can't fix them."

"The significance of the steam engine is not only that it can be put into various productions such as electricity generation, but also that our demand for it will force various technological advancements."

In fact, he doesn't know much about this aspect, and there is no way for him to improve the existing shortcomings, but the craftsmen in the engineering department who specialize in equipment and engineering are putting more and more energy into it, which makes Chen Mu feel more and more that the steam engine Appearing is like letting Ming enter overseas hegemony. It is a hard-working but rewarding career.

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

"Our lathe is not accurate enough, so we have to find a way to make it enough; our material is too heavy and dissipates heat too quickly, so we have to find a way to make it light so that it can retain heat. All development comes from demand. Without demand, people I'd rather lie at home and drink ice water."

The reason why he can be reasonable is because Chen Mu doesn't want the old fans to see through his true colors of ignorance.

"People will think about it when the demand comes, and when they think about it, there will be extraordinary creativity, and technology will naturally improve."

As he said that, Chen Mu pointed to Zhou Sijing's steam engine, and said, "If you change the wind wheel into a harder and lighter material, and push the fan blades multiple times to guide the direction of the steam, the wooden cart equipped with the steam engine will be larger. A flatbed car with two front wheels and two rear wheels, the front wheel guides the direction, and the rear wheel is connected to the wind wheel with gears... If the car is light enough and the steam engine is light enough, can it run?"

　Then push "I stopped for two days"

　　Restart for 48 hours, what do you want to do?what can you doWhat are you going to do?
　　Zhou Ping's life, after waking up, changed!

　　Whether it's confusion or madness, nobleness or depravity... it will all stop in these two days!Or, the next two days...
