Tang Dynasty good brother-in-law

Chapter 998 The copper wire needs to be pulled
Compared to the complete shock of Qin Qiong and others, Li Shimin was ecstatic.

One's own orders can be transmitted thousands of miles away, and a cup of tea is enough, so it can be said to be infinitely useful for military command, civil administration, train passage, etc.

With the telegraph, there will be electric lights, and then electric motors.

The industrial era of Datang was the beginning of the curtain.

Li Shimin was very calm about the telegraph, even if he knew the name of the telegraph, he would call Lei Yinji according to Liu Mu's new name.

The eldest grandson Wugou and Dugu Lanruo were surprised that there was such a magical weapon.

During the pleasant surprise of the two women, they even learned some telegraph knowledge.

Li Shimin and Liu Mu frowned.

"Where is the difference?" Li Shimin was not asking the researchers here, nor was he asking Liu Mu, just talking to himself.

Liu Mu also doesn't understand that the principle is the principle, and the product is the product.

Mistakes in any link may turn the product into a waste product, not to mention that the telegraph machine manufactured now can really transmit five hundred miles, but it will be scrapped after not many times of use. This is the reason why Li Shimin frowns.

And the cause of each damage is the same, the coil is damaged.

An official in charge of the institute is reporting.

"Sage, we have analyzed various reasons, and we are constantly improving the machines and solutions for making the wires. We believe that the problem lies in the copper wires. Right now, the batteries, the power generation pedals, and the wires..."

Liu Mu stood there and listened for half an hour, then suddenly said: "Drawing machine!"

"What?" Li Shimin didn't understand what Liu Mu was talking about.

Liu Mu also suddenly thought of it, and explained immediately: "The copper wires used now are rolled out. Such copper wires seem to be the same thickness, but they must be unqualified if they are placed in small places. The copper wires should be pulled out. , not pressed out."

After listening to Liu Mu's explanation, Li Shimin immediately asked, "Who has ever heard that steel wires are pulled out?"

Hundreds of excellent craftsmen stopped their work, and an old steelsmith came forward to report after getting permission: "Sage, when making copper chariots and horses in the former Qin Dynasty, copper wire was drawn out. Using familiar The copper rod is heated and pulled out, this craft is not too difficult."

Liu Mu asked, "Is it possible to evenly pull out copper wires that are thousands of feet long and exactly the same fineness?"

"It was definitely not possible before, but if there is a steam engine that can guarantee a stable speed, it is possible."

Li Shimin immediately ordered: "Two, prepare two steam engines of the best quality for them, and prepare them immediately."

"Brother Huang!" Liu Mu would still call Li Shimin "Brother Huang" when there were outsiders: "This matter should not be rushed or rushed. Let them experiment slowly, this is only half a step away from success."

Li Shimin nodded: "What else do you need, I will double it to you."

"The sage and the minister decided to start over and check all the craftsmanship. The reason for the damage is the same every time. It suddenly became very hot when it was in use, and then it was damaged. According to the knowledge I have accumulated about lightning, After a section of copper wire passes through lightning, the thinnest places will heat up."

Li Shimin nodded: "I have seen your efforts. You have worked hard for this Leiyin machine for a long time. A journey of a thousand miles begins with a single step. You have completed the first stage, and this is also the end of the second stage. I believe that you will be able to overcome many difficulties, and Leiyinji will benefit Datang."

"I will wait...

From the manager of the research area to the young apprentices, they all said that they would go all out and try their best to solve the problems in front of them, and they would definitely live up to the grace of God.

Liu Mu persuaded from the side: "Brother Huang, it's been a while since you left Chang'an, why don't you go back to Chang'an and wait for the news?"

"it is good!"

Li Shimin also understands that if he wants to live here and stare at him every day, the efficiency of these people will be reduced several times.

Every day is just stressful.

A few days later, Li Shimin and Liu Mu returned to Chang'an City.

"Second brother, I returned to Chang'an not because of the telegraph, nor because of the airship, nor because of the train. I wanted to establish the Royal Academy of Sciences of the Tang Dynasty. The people in Huayuan have hardly left Huayuan over the years. They are busy day and night. It was very hard. I want to give them an honor."

"Yes." Li Shimin agreed without a second word.

Liu Mu took out a thread-bound book with frayed corners and put it on Li Shimin's desk.

Li Shimin picked up the book with great curiosity.

After opening it, I found that it was not a book at all, but a bound blank book with a plan written in it.

Li Shimin originally planned to laugh at Liu Mu for using such a dilapidated blank book, but when he looked at the contents, Li Shimin was deeply attracted, and he didn't care whether the outer cover of the book was damaged or not.

It's a plan.

The content of the plan is that Huayuan is Datang's top research institution, and if all projects, large and small, are all researched by Huayuan, it will definitely limit Datang's technological growth.

If part of the content is divided out, it may have a miraculous effect.

After flipping through a few pages, Li Shimin put Liu Mu's plan on the table: "Have you been writing this for a long time?"

"Yes, it's been about a year and a half. I often open it and look at it, and then think about what shortcomings I have before continuing to write. Datang can make the Mediterranean feel coercive right now, because Datang surpasses them by several hundred. With years of scientific and technological strength, how to maintain technological excellence?"

After hearing Liu Mu's words, Li Shimin said: "Take copper wire as an example. If Chang'an City puts up an announcement to purchase extremely high-quality copper wire, it is estimated that some craftsmen from somewhere have sent samples of copper wire to Chang'an, and there must be very good ones. "

"Second brother, the first driving force that really promotes the power of science and technology is war. But Datang will have wars, but there will be no enemies that make Datang feel embarrassed or invincible, so the power of war is not enough to promote Datang's technology."

Li Shimin nodded and then signaled: "Continue."

"Then there is another way, that is silver."

"Money?" Li Shimin's first thought was to give a lot of money to encourage him.

Liu Mu said: "Datang's looms have been improving. It can be said that wooden looms have reached the extreme, and more efficient looms made of pure steel have entered rapid development."

After pouring himself a cup of tea, Liu Mu continued: "Again, I always think that our boats are already very good. In fact, the construction of boats is still improving, and some private boat workshops have surpassed official boat workshops in some small technologies. .”

Li Shimin clapped his hands lightly: "Second brother understands that earning coins is also the driving force for technological development."
