Start Being a Vassal King Today - Chapter 745

[Chapter 745]

“That’s right, everything related to electricity.” Zhao Xu smiled, “Do you still remember the voltaic battery and wired telegraph I mentioned?”

“Of course I do.” Wang Chong scratched his head, Suddenly I felt a little embarrassed, “To be honest, I even secretly made a joke.”

Zhao Xu laughed dumbfounded when he heard this, “So, today I can see a ready-made one? You go and get the voltaic battery, In the next two days, I will build a laboratory cable for the king.”

There is still a gap between the laboratory and the actual thing, which can be said to be a simplified version.

Because one thing needs to improve many details from the laboratory to the popularization.

“Yes, the voltaic battery is in the minister’s room.” Wang Chong frowned, and called a student to fetch it.

He has been living here since the Institute was built.

Food, clothing, housing and transportation are served by dedicated personnel, and they only need to concentrate on research and development.

After a while, a student came over with a cylindrical metal object.

It is the voltaic battery.

This cylindrical metal is not a whole, but like candied haws, with a copper stick in the middle, and then a round copper sheet with a hole in the middle, paper soaked in salt water, and zinc sheet stacked together in order.

Separated, these three are nothing, but stacked together they become a battery.

Copper wires are tied to both ends of the middle copper rod, which can be used for wired telegraphy.

Therefore, in the nineteenth century, there was often a large box next to the telegraph, and the empty spaces in the box were filled with voltaic batteries.

Seeing the voltaic battery with his own eyes, Zhao Xu nodded slightly, “Don’t forget the cable telegram, this king doesn’t need me to participate in this, right?

” I’ve got a wine bag and a rice bag.” Wang Chong looked confident.

In the study of electricity, voltaic batteries and wired telegraphs are the most basic things, which are easier than steam engines, but it becomes more difficult as you go to the back.

All he needed was copper and iron wire and a few copper plates, and he could make a wired telegraph in two or three days.

“Even so, I will give you three days. After three days, I will see the cable from the laboratory.” Zhao Xu set a deadline for Wang Chong.

He has confidence in Wang Chong. Under the current industrial foundation, he can easily use a lathe to manufacture cable telegraph parts.

However, some telegraphs are easy, and the really difficult problem is the transmission of messages by wire telegraph and the laying of wire cables.

The first wired telegraphs sent messages in Morse code.

He also has to come up with a set of such codes, and accurately transmit messages by tapping the long and short frequencies to match the corresponding text.

Solving this problem involves cable laying.

Wired telegrams that cannot transmit information to various parts of Daesong are useless.

This cable is a combination of copper and iron wires.

It is necessary to wrap the copper wire and the iron wire separately with oiled paper to prevent contact and short circuit, and then wrap a layer of cotton yarn soaked in linseed oil around it.

Although the process is not difficult, at least thousands of kilometers of cables are needed to cover Jiangbei with wired cables, which is not a small project.

Therefore, he said that the wired telegraph in the laboratory is easy, but it is not easy to popularize it.

But just like laying railways, there are also difficulties in promoting the development of Dasong.

He doesn’t want one day when his army is fighting overseas, and the other party sends a wired telegram to the battlefield, commanding and dispatching on the spot.

And his general had to send someone back by boat to ask for instructions.

After instructing Wang Chong about this matter, Zhao Xu left the research institute.

After the wired telegraph was developed, Wang Chong could conduct various electrical experiments until one day he was able to build a thermal power plant, output electricity through transformers, and usher in the second industrial revolution.

Coming to the street, Zhao Xu didn’t go back to the palace immediately, but went to the science and technology school.

After Wang Chong’s group of students graduated, the science and technology school did not stagnate, but continued to recruit new students, and even expanded the number of students.

Walking in the school, except for a few old students who stayed in the science and technology school to teach, all of them were new faces.

Many people study hard in the hallway of the school with textbooks.

Satisfied with the current situation of the Science and Technology Academy, he went to the Military Academy, Government Affairs Academy, Naval Academy, etc.

The same is true for these schools, all of which are in order and have established a sound school management system.

Dasong’s talent training system has initially matured.

Without his worries, a large number of talents can continue to emerge every year.

In the future, with their efforts, the development of Dasong will only get faster and faster.

After inspecting the school, Zhao Xu finally went to the Military Division.

The war in Goryeo is over, but the cloud of war still hangs over Daesong.

The Dongtu Alliance is determined to destroy Dasong, and after Koryo, it will definitely not stop.

On the military front, he cannot relax.

After all, this is an era of great changes in weapons.

Xitu’s technology is also constantly advancing. Within a few years, breech-loading guns, breech-loading guns, and iron-clad ships will appear one after another.

“How about the rifled gun?” Zhao Xu asked directly when he arrived at the Military Division.

He has been in Korea for so long, I believe Wang Ying must have some clues.

This time, he wanted to replace some of the guns of the sailing warship before the steam engine was launched.

In order to completely destroy the British fleet in the East in the next naval battle.
