Back to Ming Dynasty with Industrial Revolution System

Chapter 266
In the Physics Department of the Academy of Sciences, Chu Yun assembled a group of physicists.Among them are Sir Humphrey who studied arc lamps, Faraday, the father of electricity, and a group of physicists who studied electromagnetism.In addition to this, there are several chemists who collaborate across disciplines.

"I have an idea for making a practical electric light, but it's just an idea. Whether I can actually invent it or not depends on everyone." Chu Yun said to the physics experts gathered together.

That's right, Chu Yun thought of a very important invention in the history of electrical appliances - the electric light.With electric lights, it is equivalent to giving the city a nightlife, which can greatly promote production and consumption, and its significance is extraordinary.

Chu Yun immediately thought of the industrial revolution system and wanted to turn on the electric light technology.However, the industrial revolution system humiliated Chu Yun again.The "carbonized bamboo filament incandescent lamp" technology invented by Edison requires 5 civilization points.General Electric's "tungsten incandescent" technology requires 20 civilization points.

With so many points of civilization, Chu Yun's flesh will be hurt for a long time.So Chu Yun does not intend to turn on the light technology through the system.Instead, use your own understanding of electric lights and existing scientific talents to develop electric light technology by yourself!Lighting technology is not too complicated a project, and there are system rewards for self-development.

"I have two bold ideas, one is carbonized bamboo filament incandescent lamp, which can be used for about 1000 hours. The other is tungsten filament incandescent lamp, which has higher brightness and longer life, but the large-scale manufacturing technology of tungsten filament filament is relatively Difficult." Chu Yun shared his understanding of electric lighting technology in his impression.

"Can you explain in detail, my lord. I have tried 2000 batteries and two carbon rods to make an arc lamp, but this arc lamp is too bright, produces too much heat and is not durable, so it cannot be used in ordinary places." Humphrey Sir Leigh asked with burning eyes.

This is his field of research, and every breakthrough is what he dreams of, and it is even possible that he will not be able to make great progress in his entire life.Now that Chu Yun has proposed a new concept in the field of electric lights, how can he not be excited.

"My idea is this. An incandescent lamp consists of a bulb and a filament. We energize the filament and use resistance to heat the filament to an incandescent state. When the temperature of the filament reaches a certain level, a visible electric light source can be emitted. .”

"The material of the filament can be carbonized bamboo wire or tungsten wire, both of which are good materials. But I don't know how to make these two materials into filaments, and you need to study and try for details."

Chu Yun expressed his unsure thoughts.

"Using the thermal radiation of the filament to emit visible light? This is really amazing, and the temperature is estimated to reach 2000 to 3000 degrees Celsius." Humphrey said, "However, there is another problem that bothers me, that is, the filament is heated. It is extremely easy to be oxidized in the state of being in a state, and it will be exhausted in a flash, and it can't even last for an hour."

"So we need a light bulb, which is a vacuum glass bottle, and then fill it with inert gas such as nitrogen to prevent excessive oxidation. That's why I invited several chemists to invent the electric light together." Chu Yun said.

"Wonderful!" The knowledgeable physicists, including Humphrey, exclaimed.

According to Chu Yun's idea, maybe it really works.

"But I still have one last question, which is how to evacuate the air in the glass bottle." Humphrey said, "Our vacuum technology is pretty bad, and it may not be able to achieve a high vacuum."

"I have also considered this point. I brought a vacuum pump to support your research on electric lights." Chu Yun said.

Since it was impossible to fully activate the electric lighting technology, Chu Yun activated some of the front-end technology to save the country with curves.This saves quite a bit of civilization.

"Vacuum pump? Let's take a look!" Physicists and chemists were excited when they heard that more advanced instruments were coming.

With such technical support, various improvements need to be made next, and it will be a matter of time before electric lights are manufactured!Chu Yun was very pleased to see that the scientists were excitedly working on the arrangement of the project.Some scientists are responsible for the manufacture of vacuum bulbs and filled with inert gas, some scientists are responsible for manufacturing practical filaments, and some scientists need to study the use of direct current provided by the circuit to provide electric lamps, etc.

It seems simple, but it is actually very complicated. Just like the electric light invented by Edison, it has been accumulated by the predecessors for decades. If the vacuum pump can't come out, it will be difficult for Edison to invent a practical light bulb.

"I hope to develop a practical electric lamp next year, and then promote it to household electric lamps and street lamps." Chu Yun imagined it this way.

"...the pressure is a bit high." The scientists of the electric light research and development team expressed the pressure.

"Try your best, and I'll give you a big bonus after you finish it." Chu Yun said, "It's also easy to talk about future research funding."

R & D funding? !These scientists became more motivated when they heard about Chu Yun's reward plan.

After providing the idea of ​​lamp design, Chu Yun left the Academy of Sciences very satisfied.The next step is to see these big cows working hard. It is good for Chu Yun to receive the report of the electric light research and development team on a regular basis.

"Hmph, there will be no difference between day and night in Jinzhou City in the future." Chu Yun said happily.

Gradually, some electricity-related technologies have been developed, and the technologies of the second industrial revolution will also appear in Liaodong and Liaonan.The next generation of electric power technology should be more practical technologies such as alternating current, telephone, and wireless telegraphy.

"Erlinchen from the Ordos tribe has also come to Jinzhou City, right? Why don't you call him over and visit Manggus together?" After Chu Yun left the Academy of Sciences, he went to visit Manggus who was recuperating in Jinzhou City.

"Yes, someone from the intelligence department has been following his whereabouts. He is at the inn in Jinzhou City. I will ask someone to inform him." Yu Cheng said.

"Well, I don't know if they know each other." Chu Yun led a few guards and walked towards the south of the city.

As expected of an important figure in the Horqin tribe, Manggus also bought a spacious house in Jinzhou City, where land prices are rising day by day.

"Facing north and south, the location of this house is good." Chu Yun came to Mang Gusi's house.

E Linchen, the leader of the Ordos tribe who was resting at the inn, heard that Chu Yun invited him to visit Manggus, so he packed up and hurried over with two of his subordinates.

"Mr. Chu, I didn't expect you to remember us who came to Jinzhou. It's a great honor to be invited." E Linchen said, "Manggus is a figure of the older generation on the grassland. Back then, he and other tribes and Jurchens When we attacked each other, I guess I was only this young. I have met him a few times, I don’t know if the old man still remembers me.”
