Chapter 838 Power Blueprint

"Hey, I don't dare to talk nonsense." Wang Chong made a gesture of invitation, "Your Highness, you can go to the research and development institute to have a look." "

Zhao Xu nodded, and Wang Chong left the palace and went straight to the research and development institute.

In a tall mechanical laboratory of the R&D Institute, Zhao Xu saw a huge triple-expansion steam engine.

The steam engine almost filled the laboratory space.

This is a triple-expansion steam engine dedicated to ships.

With it, shipyards can build warships and large steamships that are more than 30 meters or even 200 meters long in the future.

The length of Titanic using a triple-expansion steam engine is 269 meters.

From then on, Dasong's shipbuilding industry will enter a new stage, officially leaving behind the Xitu shipbuilding industry.

"It's really a huge thing, amazing, amazing." Zhao Xu couldn't help but admire.

In front of the triple-expansion steam engine, he was like facing a steel giant.

Zhao Xu was praising the three-expansion steam engine. Wang Chong thought he was praising him, so he said humbly: "Your Highness is overly complimentary. If His Highness had not provided the mature drawings of the three-expansion steam engine, I would not have been able to complete it even in three to five years." It's made."

Zhao Xu was startled for a moment, then he patted Wang Chong on the shoulder, "Even so, you have done a lot of hard work. Later, I will ask the treasury to allocate some money to you and reward the students who participated in the research and development. "

"I thank Your Highness for them." Wang Chong said happily.

After thinking for a while, Zhao Xu added: "Now that you have mastered the technology of triple-expansion steam engines, please discuss with the head of the steam engine workshop and the head of the Ship Department, Chen Shou, to jointly participate in the development of the ironclad ship."

There are many things involved in an ironclad ship, and all Chen Shou and the others can build is the hull.

The manufacturing and installation of triple-expansion steam engines, the manufacturing of ship armor, and the special naval guns for ironclad ships all require the responsibility of different departments.

Later, he would have to go to the Military Division to ask Wang Yingye to contact Chen Shou.

"Yes, Your Highness." Wang Chong responded.

After walking around the triple-expansion steam engine again, Zhao Xu satisfied his curiosity, and then left the laboratory with Wang Chong.

After all, this was the first time he had seen a real triple-expansion steam engine.

Walking along the corridor in the research and development hospital, Zhao Xu's eyes swept across the laboratories.

There are busy students in every laboratory.

They are either one person or three or five people, and they are responsible for developing different technologies.

When he passed Laboratory No. 8, his eyes suddenly froze and he stopped.

At this moment, a student in Experiment No. 8 was shaking a handle. There were stone-like things on the shelves on both sides of the handle.

Wang Chong noticed Zhao Xu's eyes and said, "Your Highness, this is an electric power laboratory."

"How's the progress?" Zhao Xu asked as he entered the laboratory.

"Li Wei, please introduce to His Highness." Wang Chong heard this and said to the busy students.

According to King Yan's request, he is currently responsible for the overall coordination of the entire research and development institute.

Unless it is an emergency project, he will not personally participate in the research and development, but will fully tap the talents of the students.

"See your highness." Hearing Wang Chong's voice, Li Wei came back to his senses and hurriedly saluted Zhao Xu.

"No courtesy." Zhao Xu smiled and patted his shoulder.

He has always been friendly towards these students, treating them like teachers and students.

This is to demonstrate the importance he attaches to scientific and technological talents.

The effect of guidance is also quite good. The number of students applying for science and technology schools is increasing day by day, and most of them are no longer focusing on the official examination.

"Your Highness, I am conducting an electromagnetic cutting experiment. The results of the experiment prove that electromagnetic induction can generate electricity." Li Wei was not a good talker. After saluting, he introduced it directly to Zhao Xu with a businesslike look.

"Well, in that case, is it time to develop a generator?" Zhao Xu asked.

The two stone-like objects on the left and right in front of him are actually magnets.

The thing Li Wei shook just now was a rectangular coil.

It is a square iron frame wrapped with copper wire.

By shaking the handle, the rectangular coil rotates between the magnets, generating electricity.

So, this is the most primitive generator.

"Yes, Your Highness, I am about to develop a formal generator next, but this will be a hand-operated generator. If successful, it will be the development of a large generator." Li Wei said with a straight look.

Zhao Xu nodded. In fact, he had already asked the R&D Institute to carry out electrical tests.

But now, Li Wei's electricity experiments are still in their earliest stages.

He did not pursue this question because he knew that the materials for the electrical experiment were unavailable and would take some time to collect.

Such as magnets.

Jiangbei naturally does not have the ability to produce artificial magnets at the moment, so the magnets Li Wei uses are natural magnets, such as magnetite.

However, although it is not easy to obtain magnets, it is not difficult either.

The ancients have known about this kind of thing that can attract iron for a long time. During the Spring and Autumn Period and the Warring States Period, the book "Guanzi" said, "If there is a magnet on the mountain, there will be gold and copper underneath."

But in addition to the magnet, there is one more thing to prepare, which is an old-fashioned voltmeter.

As soon as he entered the laboratory, he discovered a voltmeter connected in series with the coil.

So, he pointed to the voltmeter and said, "Did you make this?"

Li Wei glanced at the voltmeter and said, "Yes, Your Highness, the principle of this voltmeter is similar to that of a wired telegraph, very simple."

Zhao Xu smiled with satisfaction. This Li Wei and Wang Chong were students from the same batch and were also among the top students at that time.

He spoke calmly, which showed that he had a deep understanding of electricity.

As he said, the principle of the voltmeter is similar to that of the wired telegraph.

Like the wired telegraph, this voltmeter has a coil, which will generate magnetic force as long as it is energized.

Therefore, as long as the current is generated like a battery, the switch-like structure in the voltmeter will be attracted by the coil and move the pointer.

When measuring high voltage, just install a resistor in the meter.

"Very good, I am waiting for your large generator." Zhao Xu patted Li Wei's shoulder again.

Using a steam engine to crank the handle of a large generator is the principle of power generation in a thermal power plant.

However, even if a generator is built and can produce alternating current, it does not mean that it can be used as long as there is electricity.

The transmission of electricity is also a subject.

Next, the Institute will also develop power control and transmission equipment such as transformers.

Of course, another very important thing is the wire.

"Rubber." Zhao Xu couldn't help but whisper.

He couldn't let the development of electricity get stuck on rubber.

And to get rubber, he had to take over the rubber plantations in the southern sea area of ​​​​Tongtu.

When the Marine Corps was equipped with Qin-style rifles and the next batch of sailing warships and steamships were put into service, he had to take action in Nanyang.
