PNB Chapter 206
Chapter 206
Qi Cheng continued to flip through the pages and discovered that this was another essential skill for time travel. This skill was indeed quite difficult because he could no longer remember the theorem clearly.
[Essential skill for traveling through time—generator.]
[When your power is solid, you can try making a generator. Although it can't power any machines, it can still power a few light bulbs.]
【This way, you won’t have to strain your eyes when you look at things at night. 】
Daqin
Qin Shihuang quickly got up from his dragon bed and asked his guards to quickly find Fusu and the Mohist disciples. He had been interested in electricity for a long time.
Most of the things in the host's home are powered by electricity, and the effect is surprisingly good. The refrigerator can be used to store vegetables and fruits, and they will not go bad for several days.
And there's that electric griddle, he's been coveting it for a long time.
Tang Dynasty
Li Shimin laughed out loud. Is this episode going to talk about how to generate electricity? But why does it say that only light bulbs can be used? The host's home obviously has many electrical appliances.
"Your Majesty, this is about ordinary people assembling it. A large-scale device like that probably can't be completed by one person. Just like the steelmaking mentioned last time, there is still a big difference between it and their steel plant."
"So that's how it is. Send someone over here right away to understand the underlying principles so we can build a bigger generator."
[After nine years of education, time travelers should all know the principle of electromagnetic induction, which was discovered by Faraday of England in 1831. A hand-cranked generator appeared in 1832.]
[The principle of electromagnetic induction is actually very simple. When a conductor moves in a magnetic field, or when the magnetic field changes around the conductor, an induced electromotive force will appear in the conductor.]
[To be more specific, a generator consists of two parts: a stator and a rotor. The stator is fixed and contains the coils. The rotor rotates under external force, generating electricity.]
Tang Dynasty
Li Shimin was confused when he heard it. He knew every word above, but he didn't understand how they were put together. But it didn't matter, he felt that there must be someone who understood in the Tang Dynasty.
As long as we know the materials, we can definitely make it.
Qing Dynasty
Emperor Kangxi immediately ordered the chief steward of the Imperial Household Department to be on standby and to deliver all the materials mentioned on the curtain to the palace the next morning, so that he could assemble the generator himself.
"Father, you will definitely succeed." The Seventeenth Prince came closer. "Look at the sky curtain. It says this was discovered in 1831. If the Qing Dynasty can make it, those Western barbarians will have no way to deal with us."
Kangxi snorted and said, "It's still a minor path after all. The country must be rich and the people strong before it can be successful."
……
Next, we need to prepare the materials. We usually use copper wire for coils. This was not difficult in ancient my country. We mastered the metal wire drawing technology very early.
[We need to apply a layer of insulating varnish on the copper wire. This is also relatively easy. Lacquerware has already appeared during the Spring and Autumn Period and the Warring States Period.]
[The production of lacquerware is much more difficult than applying lacquer on copper wire.]
As for the question of magnetism, it's also very simple. Natural magnets are widely distributed in my country, almost everywhere from south to north, such as Yizhou in Shandong Province and Chaoyang in Liaoning Province.
Another important part is the shaft, but as we've already mentioned the steel issue, manufacturing it isn't difficult.
Daqin
After hearing this, Qin Shihuang finally understood why steel was said to be the foundation of industry. He didn't expect that it would be used now.
“Are these techniques difficult?”
The Mohist disciples carefully looked at the recorded materials. These materials were not difficult to obtain and almost all of them could be made.
"These materials are not difficult to obtain, but it still takes some time to make them. For example, we still need to collect some magnets."
Qin Shi Huang nodded, but he urged Mohism to hurry up and not drag its feet like the steam engine that never got it done.
"Yes."
Song Dynasty
Several sea merchants got together to discuss the manufacture of electric motors. They had already almost completed their attempt to install a steam engine on the ship.
Just waiting for a good day to go out to sea for testing.
"This generator doesn't look too difficult to make. I think it can be manufactured once the principle is understood." A merchant frowned and said, "But we don't have anything that uses electricity. Why didn't you mention the light bulb?"
That’s true.
The host's home is full of electrical appliances, which they envy, but they only teach generators here, which doesn't seem to be of much use.
"Eat one bite at a time, and do one thing at a time. Let's build the generator first."
……
We also need a coil holder to make the coil better. The material can be bamboo or hardwood. During the production process, be careful not to cause short circuits between turns.
【Now that all the materials are prepared, we can make the generator. 】
First, make a circular wooden ring and glue the wound coil onto it. When making the rotor, if the magnets are square, the magnets of adjacent magnets should have opposite magnetic properties.
It is explained in great detail on the sky screen. It is very easy to make a generator according to this method, but the power will definitely not be very large.
Ming Dynasty
Zhu Houzhao summoned several people from the public and asked them whether they understood what was going on. If they had any difficulties, they should tell him immediately, as he wanted to install electric lights throughout the palace.
"Your Majesty, this does present several difficulties. Judging from the canopy, this generator cannot power the entire palace. It only shows a single light bulb."
"Then increase it!"
"This... Your Majesty, this is a hand-cranked generator. If it were enlarged, I guess no one would be able to crank it."
Zhu Houzhao nodded, but he was a little curious about how generators were made in later generations. There must be other ways to drive the rotor.
drive?
He suddenly thought of the hydraulic crusher mentioned earlier. Since that thing can be driven by water, can this generator be driven by water?
There should be no problem.
"First, make this generator." Zhu Houzhao looked at the diagram he had drawn. "There will definitely be difficulties during the manufacturing process. You will have to find ways to solve them."
Qing Dynasty
Just as Empress Dowager Cixi was about to arrange for Li Lianying to go down and find someone, a young eunuch came in with a memorial, saying that it was submitted by Grand Secretary Xu Tong.
After taking a look, Cixi was helpless.
Xu Tong, who was singled out for criticism by Tianmu, showed no remorse at all. He submitted another memorial saying that the generator was invented by Westerners and that the Qing Dynasty did not need it!
"I've heard that Xu Tong only accepts Songjiang silver, not foreign currency."
