Ampere's experiment was quite successful, and it turned out that he achieved less loss with wires with much smaller cross-sections than those with the same cross-section as those that came out of his arm. This advancement alone can save a lot of valuable copper. In addition, although in Ampere's experiment, the high voltage that the transformer of the substation can achieve is completely incomparable with the UHV of a large eastern country in the future, and it has not even developed to the point where the loss caused by the inductive reactance must be considered, and the voltage it has reached has only just reached 10,000 (equivalent to 10,000 volts in another time and space), which can barely achieve relatively long-distance power transmission, making it possible to use a larger power plant to solve the power supply of a larger city, as for the formation of a national power gridThis kind of thing, Joseph felt, he should not be able to see.

If the time were to go back a few years, it is estimated that this experiment presided over by Ampère can only be called "the final equipment commissioning", but in the past few years, Joseph has achieved enough in science, especially after discovering electromagnetic waves and deducing the relevant formula, he can be sure that he will be hated by future generations of students from high school to college - now he does not need to brush up on this aspect anymore. On the contrary, Joseph now prefers to brush up on his reputation in terms of moral character. By the way, I got myself a lot of apprentices and grandchildren who broke cattle.

When the time comes, the world will be full of disciples and grandchildren, who dares to say that Joseph is not right, Joseph's large group of disciples and grandchildren, and even the entire European scientific community will rise up to attack him - this is enjoyable to think about, isn't it? This is just like those "masters" of a certain eastern country in later generations, one by one, if you want to talk about academic creation, most of them are actually quite limited, and more of them are just knowledge sellers with European style, but because there are many disciples and grandchildren, they are all praised to the sky. Those who don't know really think that they are masters of the same level as their contemporaries Russell, Sartre, and Heidegger.

For this reason, unless it is a very, very, very historical discovery, such an epoch-making thing as Maxwell's equations, Joseph prefers to concede other discoveries and honors to his disciples. In many cases, these discoveries should have been made by these people in the original history, but now they are grateful to Joseph when they made these discoveries. Because they all felt that they had been inspired and guided by Joseph to achieve these things.

Many people even think that if they are given a different mentor, these discoveries may become a mentor's. Only a person like Joseph, who doesn't care about fame and fortune, would say indifferently: "I've discovered enough that the Academy of Sciences has to worry about how to name some physical quantities." Moreover, I have heard that in both middle school and university, there are students who hide in the corner of the classroom and scold me when they can't do math problems. This is not a good thing, and I think it would be better for you to share more of this kind of thing! "You see, what a good man he is. It is simply a model of the ethics of scientists!

Therefore, when Ampere informed Joseph of the successful results of the experiment by wired telegram. Joseph immediately sent a telegram back to Ampere:

"Hurry up and get the paper out, show it to me, and publish it in Nature, and then get ready to go to the Academy of Sciences." Well, the number of words is a little more, but the telegraph system is all of the military-industrial complex, which is used by oneself, and there is no need to count money by letters.

Upon receiving the telegram, Ampere was moved to tears. And his mentor is thinking: "Well, this year's quota is full again, haha, you can squeeze Napoleon's fame and reputation guy until next year!" Hmph, want to go to the Academy of Sciences? I'll count how many students I have......"

As for Napoleon, he certainly didn't know that his brother was trying to get him in line until he died, but he had already thought of a way to bypass Joseph's defenses. Napoleon decided to create a social academy in addition to the Academy of Sciences, and then ...... "I'm going to make a dean too!" ”

Immediately after the success of the experiment, Joseph summoned Napoleon and Lucien over, and he told Napoleon that the spectacle of the "city that never sleeps" was ready for full progress. Of course, the power plant will have to be expanded first, and the production capacity of electric lights will gradually increase. However, advertising can already be done first, and these things must also mobilize private funds to participate.

……

Caderus walked into a new store of Bonaparte General Electric, in an inconspicuous corner east of Montmartre. It is a three-storey building, with the lower two floors for shops and showcases, and the top floor for large customers.

With the identity and purpose of Caderus, he could have gone directly to the third floor. However, he still prefers to slowly turn up from the first floor, looking at various samples and sorting out his thoughts.

On the first floor, there are mainly electric lamps and other small electrical appliances for ordinary people and general applications. For example, the cheapest 25-watt carbon filament glass lamps cost one franc each. According to GE salespeople, it can work continuously for more than 500 hours under normal use. Relative to its price, such performance is already very satisfying.

But as a business-savvy man, Cardreus could tell the tone when he heard it. The first is the word "normal use", which hides that if it breaks in less than 500 hours, it is probably because you are not using it normally.

As for the latter "more than 500 hours of continuous work", it is an interesting sentence, because no one's electric light in the house will really "work more than 500 hours continuously". Therefore, as long as the light is turned off in the middle, it is not "continuous use", and it is not lit for 500 hours, then it is not a problem of product quality.

The 25-watt incandescent lamp is far from bright enough by the standards of later generations. But in this day and age, compared to the candles, whale oil lamps and the like that everyone is used to, this thing is really very bright. Of course, as long as you can afford the electricity bill, there is no brightest, only brighter.

The luminous efficiency of incandescent lamps is very low compared with those energy-saving lamps and LEDs in later generations, so under the same power, it is much darker, but it is easy to brighten, just use the power to make up. So next to the 25-watt lamp, there are 50 watts, 100 watts, of course, these are still commonly used, so the price is normal, for example, even if it is 100 watts, the price is only 10 francs.

But in the high-end lamps on the second floor, Caderus saw the kind of lamps disguised as stone that illuminated the entire Moulin Rouge when it opened. It's a 1000-watt lamp, and the price jumps straight to a thousand francs. It is said that a spotlight shade, a housing and a small fan for heat dissipation, as in the case of the Moulin Rouge, would cost 2,000 francs. The life of the bulb is still "more than 500 hours of continuous work under normal use".

Cardreus calculated that if he put two outside his nightclub, he would cost two thousand francs a month just to change the light bulbs. So after thinking about it, Caderus crossed the idea in his own mind.

In addition to high-power bulbs, there is also a type of bulb that is also extraordinarily expensive. That's the crystal light bulb. According to the salesman, this kind of bulb, unlike the bulbs blown out of glass on the second floor, is a polyhedron carved out of a single piece of crystal, and the filament used is not a low-end product like carbon filament, but a high-end atmospheric and high-grade platinum filament. So both the light and the service life have been greatly improved, for example, the same 25-watt bulb, the kind below, in normal use, can only work continuously for more than 500 hours, but with this, well, conservatively, in normal use, it can work continuously for more than 1,000 hours.

As for the price, well, it's really like the difference between a Lafite wine and a factory wine, which costs two hundred francs a lamp. So Caderus crossed it again in his mind.

The salesman, apparently seeing that Caderus was not satisfied with the price, said to him:

"Actually, sir, we have a lamp that looks very close to this, but is much cheaper."

"Oh, can you show me?" Caderus said.

The salesman pulled out a bulb from the counter that looked like the polyhedral crystal bulb.

"Sir, look at this, I won't hide it from you, the shell of this one is glass, well, there is still a difference between transparency and fine crystal, but it is not big. And it's not a direct bulb either, but a casing that you can put on the outside of another bulb and hang it a little higher, and who can tell? ”

"This cover isn't big, can you fit a light bulb in it?" Kaderus asked.

"Sir, we have a special kind of smaller bulb that fits in." The salesman pulled out a couple of very small light bulbs from the counter, "This is a twenty-five-watt carbon filament bulb too." Under normal use, it can also work continuously for more than five hundred hours. But you know, it's not easy to make things small, so it's a little more expensive, 3 francs each. And if you use it in a glass cover, it will be more difficult to dissipate heat, and the service life will be reduced. But two or three hundred hours is still fine. ”

The salesman was a little moved by Caderus, and recommended to him the "big chandelier" made of this "crystal lamp". Cardrews calculated in his heart, the price offered by Bonaparte General Electric seemed to be much higher than the price he put together, but it was still within his acceptable range. And this thing needs to be connected to wires or something, this is a technical work, and now except for Bonaparte General Electric, he can't find any other craftsman who can do this kind of work. So he really doesn't have any more options yet.

After looking at the various electric lights, Caderus went up to the third floor.
