Xue Kaiqi's sudden words immediately attracted the attention of the two, and looking sideways, Yang Lin said even more loudly: "Oh... What's the matter, Minister Xue? Why didn't you listen to you when you were on the road these days? ”

Immediately, in the puzzled looks of the two, Xue Kaiqi showed a little embarrassment, and said brightly: "That, that, marshal, that's like this, since you put forward the theory of magnetism and electricity in the weapons research institute, through some improvements, our scientists are groping to develop a generator, and the model has come out, so it's time to make a real thing."

Between the words, Xue Kaiqi answered some questions that were not asked, and there was a faint feeling of confusion. However, Xue Kaiqi became more and more excited and became more organized: "That's also, as for the light bulb you mentioned, we have developed it, but the service life is not long, the cost is a little expensive, and it cannot be promoted to the people." ”

This day was really a happy event, which made Yang Lin excited, but his face always remained calm, as soon as Xue Kaiqi finished speaking, he didn't say anything about the generator, but immediately asked suspiciously: "Oh... What is the reason why bulbs are not durable and costly? ”

"Well... Marshal, yes, the filament used for the bulb is made of white gold, and it can only remain bright for two hours. That's why I said that the cost is a bit too high to be promoted to the private sector, and I don't know exactly what the problem is, and I need you to ask those scientists and inventors. Xue Kaiqi was a little lacking in confidence, and replied in a whisper.

Uh, Zhang San's jaw of shock is about to drop, what the hell is an electric light? It's too extravagant to use platinum as a material, and it can only be used for an hour, how much a loser is this?

However, without waiting for Zhang San to sigh too much, Yang Lin continued: "Okay, in this case, I'll see them tomorrow, what is the problem with the light bulb, which makes the light bulb impossible to popularize and use for a long time." ”

When Zhang San heard this, he was even more surprised and puzzled, even if this light bulb is very expensive, a well-off family can't afford it, and the marshal has no intention of giving up. Although thinking so, Zhang San did not say anything against it, but just watched quietly.

As a college student in the 21st century, or a science student, although the principle of the light bulb is not very detailed, but the basic overview still knows a little, therefore, I don't say much, I already have an idea in my heart, just wait for tomorrow to meet the inventor in the laboratory, according to the specific time, discuss it, and say some things I know, maybe I can accelerate the birth of the light bulb.

Early the next morning, there were a large number of soldiers patrolling the research place of Kongtong Mountain, and no matter who entered or exited, they must have corresponding signs to prove their identity. Otherwise, the guns in the hands of those soldiers are definitely not vegetarian.

In the research room, many inventors and scientists gathered together, standing around the table, their eyes either focused on the set of devices on the table, or all focused on one person, that person was Yang Lin, and Zhang San and Xue Kaiqi stood on either side.

This night, Zhang San almost lost sleep all night, didn't sleep much, and was deeply hooked by the light bulb, wanting to see where the artifact was?

Yang Lin carefully checked the entire circuit, and after thinking that there was no problem, he turned off the switch, and in an instant, the light bulb lit up.

The device of the electric lamp is very simple, that is, the volt stack, switch, electric lamp, copper wire wire, during the whole operation of the electric lamp, Yang Lin said calmly: "Everyone, have you ever thought that when this platinum filament burns, the air inside will be pumped out and turned into a vacuum, will its life be longer?" ”

The people present were all knowledgeable, they were involved in various disciplines, and they knew the composition of the air and the conditions of combustion. At this moment, a man came out of the crowd, with a high nose and a hooked nose, who looked like an Englishman, but was very young, and asked: "May I ask the marshal, do you mean to extract all the air from the electric lamp and create an environment?" ”

However, Yang Lin did not answer immediately, but turned his head to look at Zhang San, his eyes showed an inquiring look, Zhang San immediately understood, and introduced loudly: "Report Marshal, this is Humphrey David of Britain, sent from the West by Zhao Xiang, he is very proficient in the study of chemistry, before that, when he was in the UK, he did an experiment that could split water through the arc to decompose water and decompose water and oxygen. ”

"Moreover, he also made achievements in mineralogy, metallurgy, tanning and agricultural chemistry, so after arriving in Guangzhou, he did not stay in Hong Kong, but sent it here, teaching our people this knowledge and working together on some things."

Yang Lin nodded, very surprised in his heart, it seems that Zhao Xiang's West has made some achievements, and he has begun to collect various scientific and technological talents from the West for himself. Yang Lin didn't hesitate any longer, smiled kindly, and said softly: "Not only that, but my suggestion is that since there are only a few light bulb structures, glass covers, filaments and terminals for access circuits. Then, what we can change is not only its use environment, but also the internal improvement is the use of filament materials. ”

As soon as these words came out, listening to Yang Lin's meaning, it seemed that there was a bigger move waiting behind, and he was even more attracted to his mind, especially Humphrey David, who felt that this trip to the East had come to the right place, this ancient country not only had four major inventions, papermaking, gunpowder, compass, printing, but also no shortage of scientific talents, everyone was waiting for Yang Lin's incisive insights.

"As far as I know, in the beginning, the filament of the bulb was made of carbon ink, and the use time was only three minutes, in this case, there is a precedent, why don't you consider changing the material and replacing the white gold."

Just as Humphrey David was about to say something, Yang Lin's voice sounded again: "I know a material whose properties are not only resistant to wear and tear, but also resistant to high temperatures, as long as its mineral deposits are found and excavated in large quantities, it can be put into practice and promoted." ”

"That's... Marshal, what is the material? Xue Kaiqi immediately asked.

"Tungsten, use tungsten filament instead of platinum filament!" Yang Lin said lightly, very confident, and then took out a filament from his sleeve, and said again: "This is the filament, I got it by chance." ”

During the whole process, there were some assistants who were recording Yang Lin's suggestions, and more people were busy, walked to the side, took out the air extractor, and pumped the air inside on the basis of the original bulb, and more people came over, took the tungsten wire in Yang Lin's hand, and processed it slightly, and under Yang Lin's suggestion, a new electric light was made, which was carried out by Humphrey David.

In an instant, the electric lamp made of tungsten filament turned on, brighter and more gorgeous than the electric lamp made of platinum material.

As a science student, being able to be admitted to the undergraduate program shows that Yang Lin's chemistry will not be bad, and of course he will know some principles of batteries, especially about the electrolyte, the essence of battery formation, and the quality of the battery will be different depending on the material of the electrolyte.

Therefore, in the process of everyone's anticipation, Yang Lin once again said amazingly: "Everyone, since you are idle now, I also have some ideas about the improvement of the battery......"

However, when Yang Lin was about to continue, another Westerner stood up and said a little impolitely: "Oh... Isn't this battery good? Can't support this experiment? ”

Yang Lin was stunned for a moment, his eyes looked at Zhang San again, and in an instant, Zhang San understood, but the whole person was very embarrassed, and muttered: "That, Marshal, this is the Italian physicist Mr. Volt, who came to Kongtong Mountain with Humphrey Davy." ”

In an instant, Yang Lin was startled, and immediately said in disbelief: "You are Volt?" The Italian physicist who made the voltaic battery? ”

In an instant, Yang Lin suddenly realized, is it any wonder that when he proposed to improve the volt battery, this old man in the West reacted so much? No matter who it is, once someone questions his work, it doesn't feel very good.

It seems that Yang Lin will know that he will know, and he did not expect Yang Lin to know that the volt battery was invented by himself, Yang Lin's reaction, Alessandro Volt is very useful, and he can't help but feel a little proud, and said in a somewhat lame and stiff Chinese: "Yes, it is me, Count Alessandro Giuseppe Antonio Anatacio Volt, this battery was invented by me." ”

However, speaking of this, all of a sudden, Volt frowned, raised his eyebrows slightly, and said with some dissatisfaction: "Oh... By the way, listening to what you just meant, it seems that you are very dissatisfied with my battery? Do you have a better one? ”

Yang Lin was a little speechless, and said secretly, could it be that scientists have such a strange temper? Look at Humphrey David, who is only focused on research, how can he think so much? Despite the slander, Yang Lin still said patiently: "Uh... Mr. Volt, it's not that I'm not satisfied with your battery, but I think that the electrolyte of the battery can be changed, maybe the effect will be better? ”

"Well... How do you want to change? The old man's dissatisfaction had faded, but he still asked with a slight frown.

"It's very simple, that is, replace the electrolyte in it with sulfuric acid, according to the chemistry of sulfuric acid, the molecules in sulfuric acid should be much more active and stable, maybe it can improve the performance of your battery."

At this time, Volt's complexion soothed and accepted Yang Lin's opinion, after all, he had traveled all over the world and had intersected with scientists and leaders in Western countries, so he felt that Yang Lin's proposal was very reasonable.

With this in mind, Volt immediately set out to experiment with his masterpiece.

Yang Lin was not a person who could be idle, seeing that everyone was either busy improving the single lamp, or accompanying the volt battery, Yang Lin, who felt idle for a while, walked out of the research room, accompanied by Zhang San and Xue Kaiqi, and walked to the research room next door, ready to see the situation of the generator research.
