Datang's free and easy concubine

Chapter 1717
The more Li Shimin thought about it, the more excited he became, excitedly said: "It seems that the generator still has many other uses!"

nonsense!Of course, generators have many uses, and generators are more useful than steam engines!Su Cheng knew this very well.

Of course, although Su Cheng is a science student, it would be nice if he could make a steam engine and a generator, but he didn't have the ability to make any complicated electrical appliances.

He can only be regarded as an enlightenment for Datang to do industry, and the real industrial development still has a long way to go.

Empress Changsun asked expectantly: "Su Cheng, is there any other use?"

Su Cheng said with a smile: "There are indeed many, many applications that need to be developed. In fact, the use of electricity is greater than the potential of steam engines. The simplest use is lighting."

"This generator does not only supply one light, it can continue to be connected to other lights."

Li Shimin couldn't help being slightly taken aback when he heard this: "Can you connect other lights?"

Su Cheng nodded with a smile and said, "That's right, I plan to replace all the lanterns in the mansion with electric lights. In the future, there will be no need to light oil lamps and candles, and the generator will be used to generate electricity directly when it gets dark."

Empress Changsun looked surprised: "Is it still possible?"

Su Cheng nodded and smiled: "Of course, in fact, every household in the entire Chang'an City can be connected to electric lights, and then use a generator to generate electricity, so that every household does not need to light oil lamps."

Is it okay?Li Shimin was very interested when he heard it, and asked, "What is wrapped in your rubber skin?"

Su Cheng explained: "Copper wire is to use copper wire to conduct current."

Copper wire?Want to spread copper wires in Chang'an City to transmit electricity?
Li Shimin couldn't help feeling tense when he heard this, how much copper would it take?
It's not enough to sell me, Li Shimin!
Li Shimin shook his head again and again and said, "I don't think it's necessary. People work at sunrise and rest at sunset. Occasionally they need to hold lamps and use oil lamps. There's no need to spend a lot of time laying copper wires and erecting electric lights."

Su Cheng just nodded when he heard this. It is a huge project to lay wires and install lights for the entire Chang'an City, and then build one or several power stations.

What the emperor said was indeed true. People in this era basically don't have any night life, and they go to bed after the sun goes down, so it's not very useful to connect the lights.

Moreover, copper in this era is still very precious, so it is not realistic to lay copper wires throughout Chang'an City, and the light bulbs and electricity bills are also not cheap.

In fact, even in the period of the Republic of China, electric lights had not yet become popular, let alone in the era of the Tang Dynasty.

Su Cheng could only sigh with emotion: "It's really unnecessary now, and industrial development still has a long way to go. I really hope that one day in the future, I can see the brightly lit Chang'an City, Chang'an City that Never Sleeps."

Chang'an Evernight City?
What the hell?

What do you do if you don't sleep and have a baby when it's dark?

Li Shimin was a little puzzled when he heard this, and pondered: "It is possible to lay wires and install electric lights for my palace."

Empress Changsun and Li Zhi nodded after hearing this. The electric lights are so bright and magical. It would be really good to install electric lights in the palace.

The more they thought about it, the more they felt that it was reliable. The palace is so big, and the palace is so big. The number of burning candles in the palace alone is not a small number every year. It seems that it would be good to install electric lights.

Although the cost of laying copper wires is not small, the money for candles and oil lamps is saved. As for the coal, it is only worth a few dollars.

Moreover, the lamp has no oil fume and is brighter.

Su Cheng waved his hand and said, "Let's talk about it."

Just installing electric lights in the palace, Su Cheng is really not interested, because electricity is quite dangerous, not to mention the emperor, even the emperor's concubine, or even the favored eunuch and court lady. .

In short, electricity is not good for anyone. If you want to use electricity, you must first popularize electricity safety education.

Upon hearing this, Li Shimin immediately asked: "What do you mean by talking again? The more I think about it, the more I feel that it is necessary to install electric lights in every palace in the palace!"

Su Cheng pondered and said: "It is really good to install electric lights in the palace, but there is no rush for this matter. The generator has just been manufactured, and the education on electricity safety cannot keep up. The most important thing is that there is not enough rubber! "

"Not enough rubber? Don't you know where the rubber is produced? Why is there not enough rubber?" Li Shimin asked with a puzzled look.

Su Cheng took it for granted: "I haven't sent anyone to get the rubber yet, of course there isn't enough rubber."

Li Shimin listened to the staring boss: "What? You haven't sent someone to get the rubber? It's not like you don't know how important rubber is. Why don't you send someone to get the rubber? You, you prodigal bastard!"

Now that Li Shimin understands how important rubber is, he thought that Su Cheng had already sent someone to fetch the rubber. He should have sent someone to scour the rubber early. According to his personality, he wanted to dig up all the rubber trees.

Su Cheng explained speechlessly: "Don't I have time to spare? Besides, the steam engine only uses a little rubber, and the current stock can be used for a long time. If you get back too much rubber, it will age too long." It won't work, and besides, the rubber just sits there and won't run away."

Even if it was enough before, wouldn't it be good to save more?
Besides, the lamps now have to use rubber, and the little that is saved is not enough.

This prodigal stuff, Li Shimin waved his hands helplessly and said: "Forget it, I don't count on you anymore, I will send people south to find rubber tomorrow, and bring back more rubber."

Although the emperor planned to send people to look for rubber, Su Cheng still planned to send people to have a look and find out what was going on there.

Su Cheng turned around and ordered: "Okay, stop it, don't burn it anymore."

The craftsmen stopped immediately after hearing this, but the charcoal fire was still burning fiercely, the generator was still rotating driven by the steam engine, and the light of the electric lamp was still very bright.

After a while, the steam engine stopped, and the electric light flickered a few times before it finally went out.

The lights were out, but the courtyard was not completely dark, for there were still lanterns hanging around.

However, after the comparison with the electric light, everyone looked at the lantern again and suddenly felt that the light of the lantern was too dim.

After the lights were turned off, they suddenly felt that the entire courtyard was darkened, and suddenly felt that the lantern had no lighting effect at all.

This is the reason why it is easy to go from frugal to extravagant and difficult to go from extravagant to frugal.

"What a magical light. Compared with electric lights, this lantern is really too dim. Su Cheng, what are you going to do next? Install electric lights in your house?" Li Shimin asked.
