Go back to the past and be a schoolboy

Chapter 276 Another Trick

"What, you're talking about that wireless telegraph? Hey, look for me. Let me just say that in China. Except for me, basically you can't find two people, including the earliest one in China. The radio machines, I bought them all."

Zai Tao, who was packing his things at home and was about to take part of the school guards to Europe when he heard the news, threw away his luggage, ran over immediately, found Cheng Nuo and made a call.

"Dean, Zaitao doesn't have much other skills, but in terms of knowledge, I can definitely say a few words about it. There is absolutely no problem in helping you palm your eyes."

Cheng Nuo, who was drafting a daily proclamation, looked up at the other party, and continued to write: "Mr. Zai, shouldn't you finish packing at this point in time and decide who to go to Europe? If you don't act, Professor Haber is really To become a 'Watching husband stone'."

Zai Tao's face was a little embarrassed for a while, and then he explained: "There are only a few things, and the personnel know the basics, so they can set off at any time."

Thinking of his purpose of coming here, Zai Tao went straight to Cheng Nuo's desk, propping the table with both hands: "Dean, you actually don't know something. In the last years of Guangxu, I was still a Belle Lord, and I went to Germany to visit Delfunken, they gave me a radio performance.

As soon as I saw that the effect was not bad, I directly bought two sets and put them in Nanjing and Beijing to inform each other, which worked very well.It was precisely because of this that Yuan Datou took a fancy to radio that he founded radio training in Tianjin. "

"What else is going on?" Cheng Nuo asked in surprise.

"Isn't that right? He is a foreigner, and he naturally wants to show off when he has good things. That is to grasp this point. When I went to Europe, I saw a lot of good things, and I even studied some gadgets. , it just so happens that this wireless telegraph machine is one of them." Having said this, Zai Tao couldn't help but say complacently.

"Not bad, Mr. Zai, I really didn't expect you to do research on this." Cheng Nuo put down his pen, picked up the manuscript in his hand, dried the ink on it, and handed it to the other party: "It's just right, please read it for me, Mr. Zai." See if there are any omissions in this proclamation."

Early radio technologies mainly include three types: wireless telegraphy, wireless telephone, and broadcasting radio stations. The earliest wireless telegraphy was introduced into our country, so radio stations mainly use wireless telegraphy technology.

Interestingly, in the second year of Xuantong, the French set up a radio station in Gujiazhai in the French Concession in Shanghai to report to ships, and cooperated with the Xujiahui Observatory to make daily weather reports.

This behavior was not approved by the Qing government, and they protested, but the French ignored it and still used it as usual.

In the year when Cheng Nuo lived, the public still controlled the radio, and radio supplies were regarded as military supplies and could not be freely imported. However, the concession has become a "talisman" for private radio installations due to its geographical advantages, and our radio technology has also developed to a certain extent. , full of irony.

Seeing the manuscript, Zai Tao took a deep breath: "Is this the broadcast we listen to every day at noon? At first I thought the dean asked other gentlemen to write it, but I didn't expect it to be written by the dean."

Cheng Nuo came out from behind the desk and leaned on the table: "In terms of radio technology, because the entry threshold for wireless broadcasting is relatively low, and the sound inherently has good propagation properties, it is conducive to the spread of our public opinion, but as an emerging technology, many People don't understand it, so naturally I will do it."

Zai Tao nodded, and after reading the full text, he said solemnly: "The words are sharp, I think there is no problem, but there is one thing I don't know, that is, we have just reached an apparently 30 yuan wireless purchase contract with the public, so we have a good relationship with each other. Maybe your relationship will be affected by this?"

Cheng Nuo raised his eyebrows and said with a smile: "The public is not monolithic, otherwise there wouldn't be so many frustrated people in Tianjin. Our appeal is not directly aimed at the public, but also refers to the environment of Shencheng, not specific organization or individual, as for the contract..."

After a short pause, Cheng Nuo got up and poured him two cups of hot tea, handed one to Zai Tao, warmed his hands and said, "It's said to be 30, but it's actually just 200 radio machines. With the proficiency of our workers, we can't It takes too much time to make it, and we can sell it to others if the contract is not reached."

If the normal trend of history is followed, the Zhifeng War will break out in a short time. At that time, the Beiyang government may change the person's surname to Zhang. If the delivery is really on schedule, it is really hard to say that these radio machines are in their hands.

But by virtue of his relationship with that young master, this might not be a bad thing.

Zai Tao thought for a while, then nodded and said, "That's fine, as long as you have an arrangement in mind, you can feel more at ease waiting for me in Europe."

Reminiscent of this trip to Europe, Cheng Nuo suddenly smiled and said, "However, Mr. Zai reminded you in time. This time it is really thanks to your arrival, otherwise there must be something missing."

Zai Tao was really confused now, he couldn't come up with a reason after pondering for a while, so he simply asked: "I don't know what the dean is talking about?"

Cheng Nuo shook his head and said mysteriously, "You'll find out when you come with me."

As he said that, he took the lead and walked ahead, calling out to Li Laosan to ride a tricycle, and arrived at Chang/Xindian not long after, pointing to a factory building and said: "The good things are here."

Looking at the big guys in the factory building in full swing, and then looking at the tall antenna, Zai Tao seemed to understand a little bit: "Could it be that our broadcasting station is built here?"

Cheng Nuo shook his head and said with a smile: "If that thing is really built here, if you meet some stunned youths from the public house and bring the big soldiers to the door, wouldn't you even bring the pot to me? Or do you continue Let's see."

At this time, Zai Tao couldn't hold back his curiosity any longer, he opened the tent and got in. After seeing the machines inside, he suddenly realized that this is the research room of radio machines.

"This... is this the production base of our radio equipment?" Walking to the workshop, Zai Tao looked left and right, feeling really fond of it.

"The production and assembly of machine parts are placed in the Shanghai Concession. There are our Huasheng Electric Manufacturing Factory and Qiuxin Machine Factory over there. The production is much more convenient than here, but here is Mr. Tesla. A temporary research laboratory, the current main direction is remote transmission." Cheng Nuo explained.

"That's good, that's good." Zai Tao suddenly realized, but then he understood Cheng Nuo's purpose for bringing him here: "You want me to bring a machine that can transmit signals over long distances to Europe. Do you want to experiment?"

Cheng Nuo said with a smile: "Yes, that's what I thought. As early as the beginning of the century, foreigners had already done the wireless telegraph experiment across the Atlantic Ocean. Now nearly 20 years have passed. Although our technology is not as good as the most advanced, but It can’t be too bad, it just so happens that when you go to Europe this time, you can bring a few of them to experiment.”

Zai Tao was very happy about this, and said happily: "This is a great thing, and the communication between us is more convenient."

Out of other considerations, Cheng Nuo specifically reminded: "However, our technology is not mature enough for such a high-power radio machine, and you may have to prepare for the user experience."

At this moment, Tesla, who was busy on the other side, saw Cheng Nuo and the two, put down their work and led a mighty group of students over, happened to hear Cheng Nuo's last words, and deliberately said with a straight face: "Comrade Dean, our radio technology is relatively mature."

In order to prove what he said, Tesla instructed the students to turn on one of the telegraphs and explain the parts in it one by one, meaning that despite the weight of the machine, the overall technology is definitely at the advanced level in the industry .

"No, Mr. Tesla, are you sure you are right? This machine has 1000 watts?" Looking at the machine and Tesla, Zai Tao expressed disbelief.

Tesla felt a little baffled, and after learning the purpose of the other two, he explained: "We are more than 1 kilometers away from Europe, if you don't use this special long-distance transmitter, how can you transmit the signal? Impossible at all."

Cheng Nuo suddenly felt ashamed, he was only interested in being happy just now, and ignored the difficulty of spanning the entire Eurasian continent, and hurried forward: "Mr. Can you get the signal?"

Tesla frowned and thought for a while, then shook his head, pointed to the battery inside the machine and said: "The Japanese 'Tongmao' battery is very difficult to use, the battery is made of paper, the quality is not good, and there are often cases of leakage and mold. , It will also cause the wire of the electric bead to break."

Zai Tao asked: "That is to say, this machine is still immature?"

Mr. Tesla took off his glasses, rubbed his dry eyes and said: "There is nothing wrong with radio technology. Although it cannot be mass-produced, it is still possible to manufacture a few experimentally, but this kind of battery really cannot drive machine."

At this point, Cheng Nuo finally realized why the radio technology had begun to develop steadily, and his mind was still restless. Now he remembered that he was far from taking action on the battery technology.

Although the first battery in history was just a dry battery made of starch added to an ammonium chloride solution, its electrolyte was just solidified with gypsum.

But such technology is not available in our country. Until the liberation, my country's battery industry has been in a backward state, and most of the storage batteries rely on imports.As for now, the domestic battery market is completely monopolized by foreign goods.

After thinking about it, Cheng Nuo made another note of the itinerary for the School of Chemistry.

It's a pity that the distant water can't solve the near thirst. Now that Zai Tao is about to leave, he urgently needs to take this kilowatt radio transmitter with him. It is impossible to wait until the domestic battery technology is mature before leaving.

Looking around, the light bulb above his head reminded Cheng Nuo, and he quickly said, "You can't carry such a big machine with you, the best way is to fix it somewhere, I think it can be directly driven by AC? Skip the battery level first, and we will solve it later?"

This sentence awakened Tesla. What he is good at is not alternating current. He has always considered portability before, and studied it according to the requirements. He even ignored the fact that high power is naturally opposed to portability. It is impossible to have both fish and bear's paw.

The more he thought about it, the more he felt that this method was feasible, so Tesla turned around and left.

Zai Tao was confused by this. He was about to ask a question when he was stopped by Cheng Nuo.

"Dean, this... this Mr. Tesla didn't say anything, and he was leaving. He didn't know whether it was feasible or not?" Zai Tao said anxiously.

"Don't worry, in the AC field, if Mr. Tesla calls himself the second in today's world, no one has the right to dare to be the first." Cheng Nuo comforted.

"But what is he doing?" Zai Tao asked again after heaving a sigh of relief.

Cheng Nuo turned around and walked away, and said with a smile, "Of course I'm busy modifying the machine. Time is tight and the task is heavy. If it was you, there is a high probability that you will do the same."

Thinking about it in another way, Zai Tao reckoned that he was too anxious, and he dared not let go of the inspiration, and he was afraid of forgetting things if his mind was slightly distracted.

"That's right, it's just a hard work for Mr. Tesla, so where are we going now?"

"Of course it's for the work-study program in France. The first period is about to graduate. It just so happens that your destination is France. Why don't you lead the team this time? They just happened to have a few sessions of radio. I can also help you in the middle of class."

"That's good, then I can feel more at ease."

"But Mr. Tesla is of Serbian origin. If you have time, go buy some Serbian specialties and bring them back..."

While Cheng Nuo's side was still intensively preparing for radio-related work, there was already a lot of noise about the radio, and the momentum was getting louder and louder.

Coupled with the end of World War I, we were a morally victorious country, and it was the time when the pride of public opinion was surging, and it caught up with the broadcast, and the national pride reached an unprecedented height.

The media is even more unwilling to let go of this hot spot. Shanghai's "Shen Bao" and "Oriental Magazine", Beijing's "Morning News", and Tianjin's "Ta Kung Pao" are actively promoting it.

"Shenbao": Newspapers from various countries, driven by enthusiasm, competed to comment first, thinking that wireless telephones, like angels, will become the most economical and convenient transportation tool between continents. Now Professor Cheng has developed radio broadcasting before the world. The symbolic event of the revival of our country, the whole country is jubilant...

"Oriental Magazine": Radio is a sharp weapon of transportation in the new era, a triumph of science, a splendid chapter in the new era, and the core force that can restore China's decline. I would like to pay high tribute to Professor Cheng and his Academy of Sciences...

"Morning News": Today's world is becoming more and more complicated, and the convenience of transportation is also more researched and improved. However, there is no broadcast by Professor Ruocheng, which can receive more than a thousand kilometers of telecommunications, so that Beijing can read the news of the happy war in Europe at the same time , the so-called reduction of the world's small shadows in one room, today's miniaturization, can not be called a non-telecom's splendor...

All of a sudden, all kinds of praise came one after another.
