Fox of France

Joseph’s words are actually quite inaccurate, but he couldn’t tell Napoleon, your eldest brother, I came here through time travel, so I aimed at light bulbs and electronic tubes from the beginning, right?

Be it light bulbs or electron tubes, in fact, their technology trees are almost the same, and their technical difficulties are almost the same. To conquer one is to conquer the other.

The first is the vacuum technology. The filament of an incandescent lamp is heated to two or three thousand degrees and emits a brilliant light. But any conductive material, at such a temperature, will undergo a violent oxidation reaction with the oxygen in the air, and then be burned. Therefore, in order to obtain a usable incandescent lamp, the first technical difficulty is to evacuate.

Another technical difficulty is the production of the filament. In the original history, Edison is said to have experimented with thousands of materials before selecting the barely usable carbonized bamboo filament.

Of course Joseph knew that the filaments of later generations used tungsten filaments. However, in this era, tungsten has just been discovered, the output is extremely low, and the melting point of tungsten is very high. It is almost impossible to refine by smelting. It can only be obtained by chemical purification, powder sintering, and then forging and drawing. But because tungsten itself is very hard and relatively brittle, it is not easy to draw wires. Ordinary high-carbon steel wire drawing dies cannot draw this thing at all, and diamond wire drawing dies must be used to produce this stuff. At that time, there were no artificial diamonds.

In this way, although it is not impossible to produce tungsten wire, the output and cost are unacceptable. Considering that there is still a gap between the technology of vacuuming and later generations, so even if tungsten filaments are used, the usable time of an incandescent lamp is still limited. In contrast, firing carbonized bamboo filament is much cheaper and simpler. Therefore, after trying a little bit, Joseph decided to follow Edison's path and use carbonized bamboo wire as the filament.

Of course, the attempt to pull the tungsten wire was not in vain. At least, in this process, Joseph's laboratory successfully fired tungsten carbide. Although the process of making this thing is not particularly perfect, but in the future, in metal processing and other aspects, this thing will be a big killer.

Today, Joseph's light bulb has been continuously lit for hundreds of hours, which is barely usable. And now there is no second competitor in the world at all, so there is no need for him to improve product performance as soon as possible. Even, in a sense, it's not necessarily a bad thing if this thing is smaller and faster.

As for the electronic tube, it is relatively more complicated, so the yield rate is still not high when it is being produced, but it is also considered that there is no competitor, so although the performance is a bit worse and the cost is a bit higher, it is still good. So, it's great to have no competition.

"What spectacle are you talking about?" Napoleon immediately got excited when he heard Joseph say the word "spectacle".

"Of course it's the 'city that never sleeps'." Joseph said, "Think about it, we replaced all the street lights in the whole of Paris with electric lights, and then installed electric lights on the most important landmark buildings in Paris. At night, the whole Isn't it a spectacle that Paris is as bright as day?"

Napoleon shook his head and said, "I thought it was something. There are street lights in Paris. What's the point?"

"Street lamps? Those gas lamps? Compared with electric lamps, the brightness of those things is like a will-o'-the-wisp in a cemetery. It's just like the fireflies are incomparable to Haoyue. Do you want to go to the laboratory with me to see the effect?"

When Napoleon heard this, he immediately opened his vigilant eyes, stared at Joseph and said, "Joseph, are you sure that what can be realized in your laboratory can also be realized in the factory? I won't be fooled a second time!"

"What is being fooled for the second time? Everything that can be realized in my laboratory will definitely be realized in the factory eventually, but some need a final process." Joseph said, but he looked at Napoleon's eyes, and immediately Added another sentence, "But don't worry this time, this thing can definitely be mass-produced in the factory immediately."

"That's good," said Napoleon, "how about we go over there right away? Well, take Lucien with you by the way."

Joseph thought for a while, and if he wanted to carry out product promotion, which businesses in Lucien's hands would definitely be able to bring in goods, so he nodded and said: "Alright, bring him too. However, at this moment, this Guys are probably already in..."

"What about him? No matter how busy he is, if we call him, will he still come? Does he want to rebel?" Napoleon said. In fact, Napoleon was quite happy to have legitimate reasons to bother Lucien while he was working (zuo le).

"Napoleon, you are probably jealous, that's for sure." Joseph said, and at the same time he added in his mind, "This sentence was really said by Lu Xun."

But Napoleon didn't know this. He smiled contemptuously and said, "Just him? Hehe, well, the Kingdom of Prussia just had a cute little public..."

Today, there are wired telephones between the most important departments in France. The technology of this thing is actually quite simple, and it takes almost no effort to make this thing. Joseph took it and established a "Paris Telephone Company", which was handed over to Louis, who had just graduated from the University of Paris.

However, because of the high cost of installation and operation (it is impossible to have automatic switches in this era, all telephone connections need to be done manually, which naturally increases the cost.) So now only the most important departments, and the most important departments Only rich people can afford this thing. Of course, Lucien met both conditions, so it was very easy for Joseph and Napoleon to find him now, and even his house in the Moulin Rouge had a telephone.

When the call was made, Lucien had just arrived at the Moulin Rouge and was about to start work. However, facing the call of the eldest brother and the second brother, he still put down the work in hand without hesitation, and rushed over immediately.

When he arrived at Joseph's laboratory, it was completely dark. Lucien got off the carriage and saw his two older brothers waiting for him at the door, so he trotted over quickly: "Joseph, Napoleon, my place is far away, and I'm rushing over here as soon as possible."

"We know this," Joseph said.

So Lucien let out a sigh of relief, and then asked, "Is there something important for you to come here at this time?"

"I'll show you something important," Joseph said. "Come in with me now."

While speaking, Joseph pushed open the door of the laboratory and walked in, followed by Napoleon and Lucien.

"Joseph, you are really, it is so dark, and there is no candle in it... I can't see anything... Oops!" Lucien was complaining, and suddenly his eyes lit up, and the strong light pierced his eyes. I can't even open it.

"This is... this is..." Lucien put his palm in front of his eyes and asked with squinted eyes.

"This is electric light. This is a new era where factories can run 24 hours a day." Joseph replied.

"My God. My eyes almost went blind!" Lucien gradually got used to it, "This thing is so bright! Compared with it, candles are like fireflies. Hmm... this thing has energy. How long will it last? How much? I think the entire 'Moulin Rouge', from the inside to the outside, including the red windmill blades, should be used for a full circle! If so, it is definitely..."

"You care nothing about the science of this thing?" asked Napoleon.

"Where do I need to care?" Lucien said, "Anyway, there is Joseph and you. What else do I need to care about? Besides, it's like I like eating tuna. Do I need to figure out how the chef cooks tuna? Well, Joseph, you haven’t answered my question just now.”

"Energy production can be used for about 800 hours. The price depends on the brightness of each bulb and the 50% profit reserved, ranging from 1 to 5 francs. This one is 1 franc. In the future, the output will be large. Yes, the price can drop to one-third of the current price." Joseph replied

"This 1 franc one should be commonly used, right? It's a bit more expensive. How about 5 francs? Joseph, can you do business? How can you only sell it for 5 francs? High-end ones should be sold for at least 50 francs! Ding goods; 1 franc, 5 centimes. Do you understand? I deal with those rich people every day, and I understand them best. They buy these, in addition to using them, the more important thing is to show off, 5 francs, how to show off ? Well, how do you use this thing?"

Joseph looked at Lucien and shook his head, then pointed to a rope hanging from the wall:

"Pull it once, and the light will turn on; pull it again, and it will be off. Try it?"

Lucien walked over and was about to stretch out his hand to pull the rope, but he stopped suddenly and asked, "Is this one going to get an electric shock?"

With the popularization and use of electricity, accidents of death caused by electric shock have not happened once or twice.

"Stupid!" said Napoleon, "that rope is an insulator!"

"I know, I'm just worried if it gets wet..."

"I just pulled it," Joseph said.

"Okay." Lucien collected himself, stretched out his hand to grab the rope, once he pulled it, there was a click, and his eyes were suddenly dark; he pulled again, and there was a "click", and his eyes were bright again; sound...

"It's so fun!" Lucien pulled it again and again... "Bada"...

"Why isn't it on?" Lucien asked in the darkness.

"It's ruined by you doing it like this!" Joseph said.

"Joseph, you also said that this thing can last for 800 hours!"

"Hundreds of hours before you mess around," Joseph replied.
