In the Department of Physics of the Academy of Sciences, Chu Yun gathered a group of physicists, including Sir Humphrey who studies arc lamps, Faraday, the father of electricity, and a group of physicists who study electromagnetics. In addition, there are several interdisciplinary collaboration chemists.

"I have an idea to make practical electric lights, but it's just an idea. Whether it can be truly invented depends on you." Chu Yun said to the physics tycoons.

That's right, Chu Yun thought of a very important invention in the history of electrical appliances - electric lights. 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 thought of the industrial revolution system at the first time and wanted to turn on the electric lamp technology. However, the industrial revolution system once again humiliated Chu Yun. The "carbonized bamboo wire incandescent lamp" technology invented by Edison requires 50,000 points of civilization point. General Electric's "tungsten wire incandescent lamp" technology requires 200,000 points of civilization point of civilization.

There are so many civilization points that Chu Yun has a lot of pain. So Chu Yun does not plan to turn on the light technology through the system. Instead, he has to use his understanding of the light and the existing scientists to develop the light technology by himself! The light technology is not an overly complex project, and there are system rewards for self-research and development.

"I have two bold ideas. One is a carbonized bamboo filament incandescent lamp, which can be used for about 1,000 hours. The other is a tungsten incandescent lamp, which has higher brightness and longer life. However, the large-scale manufacturing technology of tungsten filament is more difficult." Chu Yun expressed his understanding of electric lamp technology.

"Can you please tell me more? I have tried 2,000 batteries and two charcoal rods to make arc lamps, but this arc lamp is too bright and produces too much heat and is not durable, so it cannot be used in ordinary places." Sir Humphrey asked with a hot look.

This is the field he studied. Every breakthrough is what he has been looking forward to, and it may even be impossible to make great progress in his life. Now Chu Yun has proposed a new concept in the field of electric lights, how can he not be excited?

"My idea is this. The incandescent lamp consists of two parts: the bulb and the filament. We energize the filament and use the resistor to heat the filament to the incandescent state. When the temperature of the filament reaches a certain level, we can emit a visible electric light source."

"The material of the filament can be carbonized bamboo wire or tungsten wire, both of which are very good materials. However, I don't know how these two materials are to be made into filament. You still need to study and try it out."

Chu Yun expressed his thoughts that he was not very sure of.

"Does the heat radiation from the filament emit visible light? This is really amazing. The temperature can be estimated to reach 2,000 to 3,000 degrees Celsius." Humphrey said, "However, there is another problem that bothers me very much, that is, the filament is extremely easy to oxidize when heated, and it will be consumed all at once, and it can't hold on for an hour."

"So we need to have a light bulb, which is a vacuum glass bottle, which is filled with inert gases such as nitrogen to prevent too fast oxidation. This is why I asked several chemists to invent the electric lights together," Chu Yun said.

"It's amazing!" The knowledgeable physicists, including Hanfury, were amazed.

According to Chu Yun's idea, it might be possible.

"But I have another question in the end, which is how to evacuate the air in the glass bottle." Hanfley said. "Our vacuuming technique is quite bad and may not be able to achieve a high vacuum."

"I have also considered this. I have brought a vacuum pump that can support you in conducting research on electric lamps." Chu Yun said.

Since the electric light technology cannot be fully turned on, Chu Yun has turned on some of the pre-technology to save the country in a curve. This saves civilization points quite a bit.

"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 are needed next, and it will be a matter of time before making electric lamps! Chu Yun was deeply pleased to see that scientists began to excite the project arrangements. Some scientists were responsible for the manufacturing of vacuum bulbs and filled with inert gases, some scientists were responsible for the production of practical filaments, and some scientists needed to study the use of DC power provided on the circuit to electric lamps.

It seems simple, but it is actually very complicated. Just like the electric lamp invented by Edison has been accumulated over decades of previous generations. If the vacuum cannot be pumped out, even Edison will find it difficult to invent practical light bulbs.

"I hope to develop practical electric lights next year and then promote them to household electric lights and street lights." Chu Yun conceived this.

"...The pressure is a bit too high." The scientists from the electric lamp research and development team said that the pressure is huge.

"Try to work hard, and I will give you a large bonus after completing it." Chu Yun said, "The future research funding is easy to say."

R&D funds?! These scientists were even more motivated when they heard Chu Yun’s reward plan.

After providing the idea of ​​electric lamp design, Chu Yun left the Academy of Sciences with great satisfaction. Next, let’s look at the hard work of these big guys, and Chu Yun just received the report from the electric lamp R&D team on schedule.

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

Gradually, some power-related technologies have been opened, and the technologies of the Second Industrial Revolution will also appear in Liaodong and southern Liaoning. The next generation of power technology should be more practical technologies such as alternating current, telephone, and radio.

"The Epin ministers of the Ordos tribe have also arrived in Jinzhou City? Why not call him over and visit Mangus together." After Chu Yun left the Academy of Sciences, he went to visit Mangus 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'll ask someone to inform him now." Yu Cheng said.

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

Mangus is worthy of being an important figure in the Korqin tribe. He also bought a spacious house in Jinzhou City, where land prices are rising.

"Sit north and south, the location of this house is good." Chu Yun came to Mangus' house.

Ertian tribe leader Ertian Chen, who was resting in the inn, heard that Chu Yun invited him to visit Mangus with him, quickly packed up and hurried over with his two subordinates.
Chapter completed!
