Chapter 762: Super Ear
"Yes, everything related to electricity. Read М" Zhao Xu smiled, "Do you still remember the voltaic battery and wired telegraph that I talked about?"
"Of course I remember." Wang Chong scratched his head and suddenly felt embarrassed, "To be honest, I also secretly made one for fun."
Zhao Xu laughed dumbly when he heard this, "So, today I can see a ready-made one? You go and get the voltaic battery, and make a laboratory wired telegraph for me in the next two days."
There is still a gap between the things in the laboratory and the actual things, which can be said to be a simplified version.
Because a thing needs to be perfected in many details from the laboratory to the popularization.
"Yes, this voltaic battery is in my room." Wang Chong raised his eyebrows and called a student to take it.
He has been living here since the research institute was built.
There are special people to serve their food, clothing, housing and transportation, and they only need to concentrate on research and manufacturing.
After a while, the student came over with a cylindrical metal object.
It was the voltaic battery.
This cylindrical metal is not a whole, but like a candied haws, with a copper stick in the middle, and then the round copper sheet with a hole in the middle, the paper soaked in salt water, and the zinc sheet stacked together in order.
These three are nothing separately, but stacked together to become a battery.
Tie copper wires at both ends of the copper stick in the middle, and it can be used for wired telegraph.
Therefore, in the 19th century, there was often a big box next to the telegraph, and the empty space in the box was filled with voltaic batteries.
Seeing the voltaic battery with his own eyes, Zhao Xu nodded slightly, "Don't forget the wired telegraph, this doesn't require the king to participate in it personally, right?"
"I have learned so many things from your highness, and we can't even do this, aren't we just good-for-nothings." Wang Chong looked confident.
In the study of electricity, voltaic batteries and wired telegraphs are the most basic things, easier than steam engines, but it becomes more difficult as time goes by.
He only needs copper wires, iron wires and a few copper plates to make a wired telegraph in two or three days.
"Even so, I will give you three days. After three days, I want to see the laboratory wired telegraph." Zhao Xu set a deadline for Wang Chong.
He was confident in Wang Chong. Under the current industrial foundation, he could easily use a lathe to manufacture parts for wired telegraphs.
However, some telegraphs are easy. The real difficult problem is to transmit messages through wired telegraphs and lay wired cables.
The original wired telegraph transmitted messages through Morse code.
He also had to come up with a set of such codes, and accurately transmit messages by knocking long and short frequencies to match the corresponding text.
Solving this problem involves laying cables.
A wired telegraph that cannot transmit information to various places in Dasong is useless.
This cable is a combination of a copper wire and an iron wire.
It is necessary to use oil paper to wrap the copper wire and the iron wire separately to prevent short circuits, and then wrap a layer of cotton yarn soaked in linseed oil on the outside.
Although the process is not difficult, it takes at least thousands of kilometers of cables to cover Jiangbei with wired cables, which is not a small project.
That's why he said that the wired telegraph in the laboratory is easy, but it is not easy to popularize it.
But just like laying railways, for matters that promote the development of Dasong, difficulties must be overcome.
He didn't want his army to fight overseas one day, and the enemy's wired telegraph arrived on the battlefield, and he had to command and dispatch on the spot.
And his generals had to send people back by boat to ask for instructions.
After instructing Wang Chong on this matter, Zhao Xu left the Research Institute.
After the wired telegraph was developed, Wang Chong could conduct various power tests until one day he had the ability to build a thermal power plant, output electricity through a transformer, and enter the second industrial revolution.
When he came to the street, Zhao Xu did not return 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, they were all new faces.
Many people studied hard in the corridor of the school with textbooks.
Satisfied with the current situation of the Science and Technology School, he went to the Military School, the Political School, the Naval School, etc.
These schools are also the same, all in good order, and a complete school management system has been established.
The talent training system of Dasong has initially matured.
There is no need for him to worry, a large number of talents will continue to emerge every year.
In the future, with their efforts, Dasong will only develop faster and faster.
After inspecting the school, Zhao Xu finally went to the Armory.
The war in Goryeo is over, but the clouds of war still echo over Dasong.
The East Earth Alliance is determined to destroy Dasong, and it will certainly not stop after Goryeo.
In terms of military affairs, he cannot relax.
After all, this is an era of great changes in weapons.
The technology of the West is also constantly advancing. In a few years, breech-loading guns, breech-loading cannons, and ironclad ships will appear one after another.
"How is the rifled cannon?" Zhao Xu asked directly when he arrived at the Armory.
He has been in Goryeo for so long, and I believe that Wang Ying must have some clues.
This time, he wanted to replace some of the guns on the sailing warships before the steam engine was launched.
So that in the next naval battle, he could completely destroy the British fleet in the East.
