Daming Town Haiwang

Chapter 1819, the electrical age seems to be coming soon
Zhu Hou looked at Liu Jin's expression and smiled triumphantly.

To be honest, anyone who sees this thing for the first time will be shocked by it. It doesn't need candles, oil, or firewood, and it can light up the night like a candle.

This is a miracle, an incredible invention.

At least in Zhu Houzhao's mind.

"What is this?"

Although Liu Jin already knew that this was an early electric light, he still pretended to be surprised and asked.

"Haha, what about this thing, I named it an electric lamp, which means using electricity as a lamp for lighting."

Zhu Houzhao said with a smile: "Let me tell you, we discovered this by accident, and finally researched it after a lot of experiments."

"In the process of studying electromagnetism, we found that when the current passes through some objects with relatively high resistance, the objects will quickly heat up and become hot, so we wondered whether it is possible to study this phenomenon separately."

"Inadvertently, we also discovered that when the current is large enough, it is not just as simple as heating and heating, but also gradually glowing, and then becomes as bright as a candle, or even brighter than a candle. "

"So I devoted myself to researching this thing, and gradually discovered many interesting things. After thousands of experiments, we also slowly researched the electric light in front of us."

"It is a silk thread obtained by carbonizing cotton thread. If it is made into a spiral shape and connected to an electric current, it will emit a bright light. The intensity of this light is much stronger than that of a candle."

"And it can last for dozens of hours!"

Zhu Houzhao couldn't hide secrets and things at all, he didn't need Liu Jin to ask anything, he would tell everything by himself.

"Cotton filament carbonization?"

When Liu Jin heard this, he frowned immediately. Shouldn't the filament be made of tungsten filament?
Can this cotton thread also be used to make filament?
Naturally, Liu Jin didn't know it. In fact, in the history of the development of electric lamps, in the early days, when scientists conducted research, they used cotton filaments, bamboo filaments, etc. to carbonize first, and then they could be used as filaments. , until later, at the beginning of the 20th century, the Austrians invented the tungsten wire.

Compared with cotton and bamboo filaments, tungsten filaments are brighter and have a longer lifespan, which really makes electric lights enter thousands of households.

"Yes, non-carbonized cotton will be burned directly. Only after carbonization can the cotton be used as a filament, and it will emit bright light after being powered on."

Zhu Houzhao nodded and said: "In fact, not only cotton filament, but also many plant fibers can be used as filament. We have also tested hundreds of plant fibers and found that cotton filament is relatively the best filament. "

"Why not use wire?"

Liu Jin thought for a while and said.

"Metal wire is not good, because the melting point of metal wire is generally not good, and it often melts immediately when it is energized. The wire after carbonization with these plant fibers is different, and it will not melt all at once."

Zhu Houzhao quickly said: "I have tried using copper, iron, aluminum, lead, gold and silver, etc., but they all don't work, and they will melt away soon, so there is no practical significance. At present, only this carbonized cotton thread is relatively It can be used for a longer period of time and can be illuminated for dozens of hours."

"That's it~"

"Then this should be related to the melting point. If it is made of metal wire with a high melting point, I feel that it may be much better than cotton thread."

Liu Jin touched his chin and thought for a while.

"You are so smart, you immediately thought of the key point."

"This is indeed related to the melting point. The melting point directly determines the life of the lamp."

"Metals generally have good electrical conductivity. If metals are used to make wires, the brightness will indeed be stronger than the cotton wires in front of us, but there is still no metal wire that can withstand high temperatures."

"According to the data we calculated, after the electricity is turned on, the temperature of the electric filament is more than 1000 degrees, and this temperature can already melt almost all the metal filaments."

"Of course, there are not many types of metal wires for experiments at present. Later, I will ask people to continue to experiment with various metal wires. Each metal has different characteristics. Maybe we can find some high-temperature-resistant metal wires. come out."

Upon hearing this, Zhu Houzhao immediately gave Liu Jin a thumbs up.

This Liu Jin is really evil enough, and he immediately thought of the key point. Regarding the melting point, Zhu Houzhao and his team also decided after many discussions.

Liu Jin discovered the crux of the problem at a glance, knowing that the key point of the filament is related to the melting point, which is really admirable.

"In my opinion, in fact, it is not only the material of the filament that determines the service life, but also the reaction of the filament."

Liu Jin thought for a while and said again.

"How to say?"

Upon hearing this, Zhu Houzhao asked quickly.

"The last time I went to Imperial College of Technology, I heard the professor of Imperial College of Technology talk about the complexity of the air. There are oxygen that can be used for human and animal breathing, and some gases that are useless."

"According to their research, they believe that oxygen is a very active gas, which can easily react with some things. For example, oxygen is needed when burning. Without oxygen, candles cannot burn."

"Your filament is directly exposed to the air. After being energized, it will generate high temperature, which will easily react with the oxygen in the air, causing its lifespan to decrease sharply."

Liu Jin pointed out to Zhu Houzhao some key points of making and lighting lamps in later generations.

Electric lamps, electric lamps, not to mention filling inert gas or something, at least you need to get a vacuum bulb, so that you can use it for a longer life.

If it is directly exposed to the air, it is strange that the service life can be long.

"Yes~"

"I actually forgot about it."

"Last time, I also heard people talking about oxygen, saying that oxygen can support combustion."

After Zhu Houzhao heard this, he slapped his thigh fiercely.

"I said, why the service life of the filaments I researched is so short, it turned out to be due to the oxygen in the air."

"Then how to solve this problem?"

Zhu Houzhao immediately became deep in thought, looking at the glowing filament, and began to think hard.

Liu Jin on the side looked at Zhu Houzhao, who was thinking hard, and looked at the researchers around him, who were also thinking hard now. Only Liu Jin, the little eunuch, didn't think about these headaches.

He is already in his sixties, and he has lived his whole life.

Originally, he had already made his mark in history. With Zhu Houzhao becoming the emperor, he also became the father-in-law Liu that everyone feared. Of course, the glory was fast, and the death was also fast.

In history, he was killed in the fifth year of Zhengde, but now it is the [-]th year of Hongzhi, which is the tenth year of Zhengde in history.

He is still alive and well, and he is still the little eunuch next to Zhu Houzhao. If there is no accident, he will be seventy years old in a few years, and he will be able to take care of his life and retire with honor.

Although he has never tasted power, he can live to old age in peace, and he doesn't know whether it is a good thing or a bad thing for him.

Sometimes it is really a blessing and a curse, and there are gains and losses.

Looking at Liu Jin, Liu Jin thought of himself. He was in such a high position, and he didn't know whether it was a blessing or a curse. Since ancient times, there were not many courtiers who could die well, especially reformers like Liu Jin, who even sat at the top. Auxiliary above this position.

Shaking his head slightly, Liu Jin put these troublesome things behind him.

At present, it seems that the electric age is estimated to be coming soon.

With the advent of electric lights, it is estimated that other related electrical appliances will spring up like mushrooms after rain.

This speed can be said to be very fast.

In history, it took hundreds of years to complete the road, but it only took about 20 years for Daming to complete it.

With the advent of electric lights and the arrival of the electrical age, the technological revolution and industrial revolution will develop and change in depth, bringing huge changes to the entire society.

In the future, Ming Dynasty may be more prosperous and prosperous, but it is also possible to have large-scale turmoil. After all, the power of capitalism will become stronger and stronger, and the system and ideology of feudal society will severely restrict capital. With the development of the two, the contradiction between the two will become more and more acute.
