Daming Town Haiwang

Chapter 1885, Practical Lamps

"I have seen Your Highness!"

Zhu Houzhao came in with his hands behind his back, and Liu Jin naturally hurriedly saluted respectfully.

"No, no~"

Zhu Houzhao waved his hand to signal that there is no need to be too polite, then he looked carefully at Liu Jin and said in a low voice, "Be honest, did you steal anything outside?"

"."

Liu Jin was speechless immediately, you think everyone is the same as you, and you will die if there are no women.

"Your Highness, I have been with His Majesty all the time, so I don't have the heart to do those things."

Liu Jin replied speechlessly.

"Haha, I'm just asking."

"You, you, are strict wives."

"This life is so short, enjoy it when you should, why bother yourself."

Zhu Houzhao laughed immediately, and persuaded Liu Jin, a good man.

"Ahem, what is your Highness looking for the minister?"

Liu Jincai was too lazy to discuss this with Zhu Houzhao. Does he have to be like you and have hundreds of women in order to be considered a life?

"Yes, yes, talk about business, talk about business."

Hearing Liu Jin's words, Zhu Houzhao started to talk about business.

"Come on, come with me to my laboratory, and show you my newly researched electric light. It is absolutely shocking."

Zhu Houzhao took Liu Jin outside, ready to show off to Liu Jin the electric light he had researched.

Sitting in the car, Liu Jin followed Zhu Houzhao to his laboratory.

The people here in the laboratory are extremely busy, busy doing various electrical experiments, and you can see bright electric lights everywhere, and these electric lights also have glass covers, which seem to be similar to the electric lights of later generations. almost.

The lights are also quite bright, not comparable to candles and oil lamps at all.

"Oh, that's a good job. These bulbs are very bright."

Liu Jin looked at the electric lights and said in surprise.

The electric light has reached this level, which means that it is fully equipped to enter thousands of households.

"Haha, that's right, don't even look at who invented it."

"Hehe~"

"After you gave us some hints and inspiration last time, Lao Liu, we did what you said, replaced the filament with tungsten filament, and made a vacuum glass bulb for it, and made the current ones. Lights out."

"The lifespan is very long, and it can be lighted for thousands of hours casually. A few bulbs have been lit for more than 200 days since they were manufactured, and there is still no problem."

"In addition, its brightness is also very good. As long as the voltage is stable and large enough, the brightness is very good. It is not a little stronger than candles and oil lamps."

Zhu Houzhao proudly introduced the light bulbs he had researched to Liu Jin in detail.

Originally, bamboo wire was used to make light bulbs, but the practicality was poor. After Liu Jin's prompting and inspiration, Zhu Houzhao led his team to carry out many experiments.

In the end, it was found that tungsten wire is the most suitable for making filaments, coupled with the use of vacuum glass bulbs, greatly improving the life and practicability of electric lamps.

It can now be used in civil fields completely, and can be used to replace candles and lamp oil for lighting.

"Not bad."

Liu Jin nodded while watching.

The electric lights have been produced, and the problem of lighting has been solved, and then various electrical appliances can also be produced, such as telephones, electric kettles, electric fans, etc., all kinds of electrical appliances can also follow the electric The arrival of the times came into being to facilitate and enrich people's lives and improve people's productivity.

"Haha~ Of course."

Zhu Houzhao's tail is so high now, he can't be proud.

"In my opinion, this is already practical, and it can be promoted to the whole society."

Liu Jin thought for a while and said.

"It's a bit difficult. Electric lights need electricity. If many people use electric lights, they will need a lot of electricity. This requires special power generation equipment. It is impossible to say that every household can generate their own power."

Upon hearing this, Zhu Houzhao immediately shook his head and said.

Although the electric light is good, it seems that it can only be used in the laboratory, and it is not realistic to enter thousands of households. When this household uses electricity, someone needs to step on the engine, which is also very troublesome. very tiring thing.

"We can build a large power plant dedicated to generating electricity, and then send the electricity to thousands of households through the line. This household does not need to generate their own electricity. They only need to install the wiring and switches to use the lights."

Liu Jin said with a smile.

With the advent of electric lights, the electrical age is about to start. Isn't it just electricity? Building a power plant can solve the problem.

If there is a lot of water in the south, hydroelectric power plants can be built, and after they are built, they can sit and collect money. Electricity trading is a big business, no worse than any other industry.

After the promotion of electricity, electric lights, telephones, and various electrical appliances can also be produced. At that time, it can drive a wave of economic development, technological development, and progress of the times.

Of course, the most important thing is that you can make a lot of money.

There are dozens of industries and hundreds of fields related to electrical appliances. The electrical appliance manufacturing industry alone does not know how much employment can be promoted.

As long as it develops, Daming can be considered to have entered the electrical age, and the development of Daming can truly surpass the rest of the entire earth.

"There is no problem in building a power plant, but if the distance is too long, the transmission loss will be huge, and the voltage cannot be guaranteed."

Zhu Houzhao touched his chin and said.

For the research on electricity, he can be said to have come to the forefront, and he also knows that power transmission over long distances is a big problem.

"For the power transmission problem, high-voltage power transmission can be used, which can greatly reduce the loss. In addition, we can first conduct experiments in the capital to accumulate experience and technology. After the technology is mature, we can promote it on a large scale, and even in the whole country. Daming will promote it."

After thinking about it, Liu Jin began to express some electrical knowledge and methods of later generations. The problem of power transmission was indeed a big problem in the early days of electric power development. Some scientists even believed that electric power would never be able to achieve long-distance transmission.

Because the longer the wire, the more resistance and the greater the loss, which means that if the line is too long, the electricity that is finally delivered will be consumed and lost, and the voltage is also a big problem.

If the voltage is too low, the bulbs will not be bright enough, and some electrical equipment cannot be driven.

"High voltage transmission?"

"That's right, why didn't I think of this problem? With high-voltage transmission, the loss can indeed be smaller."

When Zhu Houzhao heard it, he couldn't help but slapped himself on the head suddenly. The whole person seemed to be enlightened all of a sudden, and he figured out the problem that he had been confused for a long time.

"But if the voltage is too high, it's not safe to use."

"You can look at transformers and turn high voltages into low voltages, or low voltages into high voltages, to solve this problem."

"When the power is transmitted, it is converted to a high voltage, and when it is used in the end, it is converted to a low voltage, which can protect users and increase safety."

"That's very complicated, and we haven't studied many of them yet."

"If there is no research, we can study it now. The big deal is to get more people involved, and strive to let everyone use electric lights as soon as possible."

"There is also a problem with the wires for power transmission. After the power is turned on, people will be electrocuted, which is very harmful and may cause death."

"We can wrap the wires with insulating rubber, which is much safer. We can use high poles to keep away from the ground for high-voltage transmission lines, which is also safer."

"Yes~"

Liu Jin and Zhu Houzhao kept discussing this matter, discussing the construction of power plants and the promotion of electric lights. These things must be done to prepare for the future. The dawn of the electric age has begun to illuminate the earth.
