The experiment led by Ampere was quite successful. It turns out that he used wires with a much smaller cross-section to achieve lower losses than those with the same arm. Just this progress can save a lot of precious copper. In addition, although Ampere’s experiment showed that the high voltage that the transformer in the substation can achieve is completely incomparable with the UHV of a later eastern country, it has not even developed to the point where the loss of inductive reactance must be considered. The voltage reached has only just reached 10 kilovolts (equivalent to 10 kilovolts in another time and space), which is barely able to achieve relatively long-distance power transmission, so that a larger power plant can be used to solve a larger city. It is possible to supply power to the country. As for the establishment of a national power grid, Joseph felt that he should not be able to see this kind of thing.

If time goes back a few years, it is estimated that this experiment hosted by Ampere can only be called "the final equipment debugging", but in the past few years, Joseph has achieved enough in science, especially in the discovery of electromagnetic waves. After deriving the relevant formulas, he can already ensure that he will be hated by later students from middle school to university. Now he no longer needs to brush up on his reputation in this area. On the contrary, Joseph is now more willing to brush up his reputation in terms of moral character. By the way, the disciples and grandchildren who have broken a lot of cows for themselves.

When the time comes, the whole world will be full of disciples and grandchildren. Who would dare to say that Joseph is wrong, that a large group of Joseph's disciples and grandchildren, and even the entire European scientific community, will gather and attack. Isn't it fun to think about it? This is like the "masters" of a certain eastern country in the later generations. When it comes to academic creation, most of them are quite limited. Most of them are just being a knowledge dealer of Europe, but because there are many disciples and grandchildren, they are all praised. Go to heaven. Those who don't understand really think that they and their contemporaries Russell, Sartre, and Heidegger are at the same level as masters.

For this reason, unless it is a very, very, very historical discovery, such as an epoch-making thing like Maxwell's equation, Joseph is more willing to give other discoveries and honors to his apprentices. Many times, these discoveries should have belonged to these people in the original history, but now, when they make these discoveries, they are all grateful to Joseph. Because they all felt that they had made these achievements under the inspiration and guidance of Joseph.

Even many people feel that if they are given a mentor, these discoveries may become mentors. It is only Joseph who is so high-spirited, so that people who don’t care about fame and fortune will say indifferently: "I have found enough that the Academy of Sciences has to worry about how to name some physical quantities. Moreover, I heard that whether it is In middle school or university, students hide in the corner of the classroom and scold me when they can’t solve math problems. This is not a good thing. I think it’s better for you to share this kind of things!” You see, what a good person this is. It is a model of scientist's morality!

Therefore, when Ampere informed Joseph of the successful result of the experiment through the cable 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 prepare to enter the Academy of Sciences." Well, the number of words is a bit more, but the telegraph system is a military-industrial complex, and you don’t need to press letters. Count the money.

Upon receiving the telegram, Ampere was moved to tears. And his mentor is calculating: "Well, this year's quota is full again, haha, I can squeeze Napoleon's reputation guy to next year! Huh, want to enter the Academy of Sciences? I count how many I have left. A student is coming..."

As for Napoleon, he certainly didn't know that his brother was playing the bad idea of ​​making him queue to death, but he had also thought of a way to bypass Joseph's defense. Napoleon decided to create an academy of social sciences in addition to the Academy of Sciences, and then... "I want to be a dean too!"

After the test was successful, Joseph immediately called Napoleon and Lucien, and he told Napoleon that the wonder of "The City That Never Sleeps" could be fully advanced. Of course, power plants must be expanded first, and the production capacity of electric lights must be gradually increased. However, advertising can already be done first, and these things need to mobilize private funds to participate.

...

Caderousse walked into a new shop opened by Bonaparte General Electric in an unremarkable corner east of Montmartre. This is a three-story building, the lower two floors are a store and display area, and the top floor is specially prepared for large customers.

With the identity and purpose of Caderousse, he could go directly to the third floor. However, he still prefers to slowly turn up from the first floor, while looking at various samples, while also sorting out his ideas.

The main exhibits on the first floor are electric lights and other small appliances for ordinary people and general applications. For example, the cheapest 25 watt carbon filament glass lamp costs one franc each. According to the salesperson of General Electric, under normal use, it can work continuously for more than 500 hours. Relative to its price, this performance is already very satisfying.

But as someone who is used to doing business, Caderousse can hear the tone of it. The first is the word "normal use". It hides that if it breaks in less than five hundred hours, it's probably because you didn't use it normally.

As for the latter "working continuously for more than 500 hours", it is even more interesting, because no one's electric light will really "work for more than 500 hours". So as long as the light is turned off in the middle, it is not "continuous use". If it is not lit for 500 hours, it is not a product quality problem.

According to the standards of later generations, 25-watt incandescent lamps are actually far from bright. But in this era, compared with the candles and whale oil lamps 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 messed up with those of later generations of energy-saving lamps and LEDs. So under the same power, it is much darker, but it is easy to brighten it. Just use the power. So there are 50 watts and 100 watts next to the 25 watt lamp. Of course, these are still commonly used, so the price is still 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, Caderousse saw the lights disguised as stones that illuminate the entire Moulin Rouge when it opened. This is a 1,000-watt lamp, and the price jumped directly to 1,000 francs. It is said that with a spotlight cover, a shell and a small fan for heat dissipation like the Moulin Rouge, the entire lamp will cost two thousand francs. The life span of the bulb is still "more than 500 hours of continuous work under normal use."

Caderousse figured it out. If he also put two outside his nightclub, not to mention anything else, just changing the light bulb would cost two thousand francs a month. So after thinking about it, Caderousse crossed the idea in his own mind.

In addition to high-power light bulbs, there is also a light bulb that is extraordinarily expensive. That is the crystal bulb. According to the salesperson, this kind of bulb is different from the glass-blown bulbs on the second floor. They are all polyhedrons carved out of a single piece of crystal, and the filaments used are not low-end products like carbon filaments. , But the platinum wire of high-end atmosphere. Therefore, both the light and the service life have been greatly improved. For example, the same 25-watt light bulb, the following one, under normal use, can only work continuously for more than 500 hours, but it is changed. This, um, to be conservative, under normal use, it can work continuously for more than a thousand hours.

As for the price, um, it is really like the difference between Lafite wine and factory wine, which costs two hundred francs. So Caderousse crossed it again in his heart.

The salesman apparently saw that Caderousse was not satisfied with the price, so he said to him:

"Mr., we actually have another kind of lamp that looks very close to this, but much cheaper."

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

The salesman took out from the counter a bulb that looked very similar to the polyhedral crystal bulb.

"Sir, look at this, I don't hide it from you, the outer shell of this is glass, um, there is still a difference between transparency and fine crystal, but not much. And it is not a direct light bulb~lightnovelpub.net~ and It's a shell. You can put it on the outside of another bulb and hang it higher. Who can tell?"

"This cover is not big, can it cover a light bulb?" Caderousse asked.

"Sir, we have a special kind of smaller bulbs that can be put in." The salesman took out a few very small bulbs from the counter, "This is also a 25-watt carbon filament bulb. Under normal use, it can work continuously for more than 500 hours. But you know, it’s not easy to make small things, so its price is a bit more expensive, each cost 3 francs. And if you put it on the glass Used inside the cover, the heat dissipation will be more difficult, and the service life will be reduced. But two to three hundred hours are still no problem."

The salesman saw that Caderousse was a little moved, and then recommended to him the "big crystal chandelier" made from this "crystal lamp". Caderousse calculated it in his heart. The price given by Bonaparte General Electric seemed to be a lot higher than the price he had put together, but it was still within his acceptable range. And this thing needs to be connected to wires or something, which is a technical job. Nowadays, besides Bonaparte General Electric, he can't find any other craftsmen who can do this kind of job. So he really has no more choices.

After watching the lights, Caderousse went up to the third floor.
