1855 United States Tycoon

"Mr. MacDonald, are you here?" Mitchell, the person in charge of the wireless communication project, greeted him first, followed by the energetic Thomas Edison.

"Ah, Mr. Mitchell, how are you preparing? Can you succeed?" Scrooge first reached out and took Mitchell's hand.

"Ah, Mr. MacDonald, the machine has been built, but we haven't had time to consider the appearance, so it looks very stupid. As for whether it can succeed, you see, this thing is still Have you tried it? I don’t know if it will succeed."

"Haha, I don't believe you didn't try it yourself first." Scrooge said with a smile, "Mr. Edison, don't you think?"

Scrooge suddenly asked Edison's head, which surprised Edison. He didn't know how to answer Scrooge, so he couldn't help but look at Mitchell.

"Haha, really, Mr. MacDonald, we have tried short-distance communication, and it is considered successful, but the distance is only tens of meters. At this distance, my mouth is better than this. This Secondly, we have to carry out a truly meaningful long-distance communication experiment. I don't know what the result is." Mitchell replied.

"I think we will succeed." Young Edison clenched his fists and said.

"Actually, you have already succeeded, haven't you?" Scrooge said, "Since you can succeed at a distance of tens of meters, it means that the design itself has no problem in principle. The rest is the question of how to improve. Let me talk about the whole process of the experiment."

"Okay, Mr. MacDonald." Mitchell began to introduce the experimental settings.

"We made three prototypes, two for communication with each other, and one as a backup. We set up the two transmitters on two hills about two miles apart near the school. There were no obstacles between them. It is convenient for communication. At the same time, as for mutual coordination, we use semaphores to carry out. The weather is good today, and we should be able to see clearly."

"A good idea," Scrooge said. "Then let's set off and visit the experimental site."

Several people got into the carriage and drove towards the hill outside the school. That hill is about a hundred meters high, and it is covered with tall larch. Now, it is early winter, and the larch has faded away from the golden needles of autumn, leaving only bare branches. A few days ago, there had been a snowfall. Now, the snow on the ground has already melted, but there is still white snow on the hills, reflecting the dazzling white light in the sun.

The carriage stopped at the foot of the hill. Scrooge and the others got out of the carriage and began to walk towards the top of the hill on foot. Edison was young and eager to start experimenting, and walked to the front in three steps and two steps.

"How is this young man?" Scrooge asked Mitchell.

"He is a good young man, although his foundation is not very good, but he is smart, studious, and hardworking. What is more rare is that he has broad ideas and rich imagination, unlike a guy like me, who has narrow thinking. What is even more rare is that he I can always remember some of the requirements of industrialized production, and put forward a lot of suggestions for improvement that are convenient for industrialization. Moreover, having a cheerful and lively young man like him in the team also brings us a lot of joy." Mitchell praised owner like this. Said the assistant.

"Well, smart and easy to learn. These two points are enough, and there are attributes of broad thinking and joy, which is too..." Scrooge thought silently, with a smile on his face.

The hills are not high, and they have reached the top during their conversation.

The larch on the top of the hill was cut down a few years ago. Although new saplings have been planted, they have not yet grown. The unobstructed mountain top is a natural place for radio stations. A wireless telegraph has been placed on an iron frame, and its whip antenna has been raised high. Not far from the antenna, a character ladder was erected. Two small flags, one red and one yellow, were placed aside. It seems that this is the place to play semaphores.

"Where is the other machine?" Scrooge asked.

"Over there, Mr. MacDonald, on the top of the mountain over there." Edison replied, pointing his finger at a mountain over there.

At this moment Bruto knew how to hand a telescope over, and Scrooge raised the telescope and looked over there. He saw a taller antenna erected on the top of the mountain over there, far higher than the larch.

"The top of the mountain over there is not as open as here. So we installed the antenna directly on the top of the pine tree. Maybe the signal will be better." Edison explained.

"Well, let's start the experiment." The wind is very windy on the top of the mountain, and Shi Gaozhi is also a person who pays attention to his own image. He usually needs demeanor and not temperature. He is not willing to wrap himself tightly with a dozen or even dozens of catties of cotton like Mitchell did. As a result, although he was wearing the best fur, he was still a little cold because he was really wearing too thin.

"Yeah, okay." Mitchell said, "Let's start. Thomas, first send a signal over there and ask them if they are ready."

"Okay!" Edison replied, and quickly grabbed the two small flags and climbed up the herringbone ladder, and waved the two small flags toward the opposite side.

Scrooge raised his binoculars and looked towards the other side. He saw a person waving a flag on a big tree on the other side.

"They said, ready, let us signal to pass." Edison shouted loudly.

"This kid's hearing is not very good. So he is always used to speaking very loudly." Mitchell explained to Scrooge in a low voice.

At this time, Edison had come down from the herringbone ladder. He came to the wireless telegraph and began to vigorously shake a hand-cranked Pixi generator placed there. The transmitter began to tap the electric button rhythmically, and the clicks of keystrokes spread out in all directions, and everyone stared at the transmitter closely.

The sender stopped sending the report and began to quietly wait for the reply from the other side. After a while, there was a rhythmic tapping sound of the pronunciation steel sheet from the transmitter. This is the reply from the other side, which shows that the first formal experiment of the wireless telegraph, a communication tool that has greatly changed the world, has succeeded!

Mitchell was as excited as a child, jumped up, grabbed Edison who was equally excited, and laughed, jumping and jumping.

Scrooge smiled and stood aside. When they were all excited, he said, "What signal did you send to them, and what response did they give you?""The signal we sent to them was'Mary has a little lamb' and their answer to us was'with a white coat of fluff like snow.'" Edison replied.

This is the lyrics of a popular children's song, so Mitchell and Edison used it as a signal to respond.

"Very interesting." Scrooge said, "but when the reporter is interviewing, I think it's better to tell them that the signal we send is'what are we facing, cheering loudly', and the reply we received is' You see, the Stars and Stripes will always fly high.' Do you understand what I mean? Saying this will help our commercial propaganda."

The two sentences Scrooge said are also the lyrics of a song. But this song is much taller than "Mary has a little lamb". This song is the lyrics of the United States national anthem "Stars and Stripes". Moreover, Scrooge asked everyone to replace these two sentences with the actual two sentences, not just because of the necessity of product promotion. Compared to Europe, United States is considered a wild land, but in this wild land, one of the people of United States, our Mr. Scrooge McDonald, uses one after another scientific and humanistic Great contributions have constantly proved that United States is not a wild country, and that United States is a member of the civilized world, and even one of the best. Now, according to his theory (United States guys will ignore Maxwell intentionally or unintentionally, and of course, the British guys will also ignore Scrooge consciously or unintentionally) have great inventions that can change the world. , And the first signal of this invention is from the national anthem of the United States. What a moving story and how exciting it should be. This story is destined to circulate throughout the United States. Scrooge is sure that many years later, the United States elementary or middle school textbooks will use this story to inspire children's patriotism. And Mr. Scrooge McDonald in this story will surely be enveloped in a circle of Sacred's halo.

"Mr. MacDonald, this machine is not mature enough. Compared with wired telegraph, its transmission distance is still very limited." Mitchell said, "Now this machine is still a certain distance away from being truly practical."

"I know that." Scrooge said. "With the pitiful power of such a Picsey generator, this machine can guarantee a communication distance of four to five miles at most. However, by using a large battery pack, a larger antenna, or an improved generator, we can definitely make its communication distance farther, maybe it won’t take long, and we can even communicate directly with the European continent through wireless communication."

"Mr. MacDonald." Edison said suddenly, "You said that you can improve the generator. I just happen to have a new idea."

"Oh? Tell me?" Scrooge looked at Edison with interest. He had new ideas just following Edison, who had studied mathematics and electromagnetics at the University of Cleveland for several months?

"I found that the magnetic force of electromagnets is much higher than that of natural permanent magnets. If we replace the permanent magnets in the generator with electromagnets, maybe the efficiency of power generation will be much higher. Moreover, the Pixi generator rotates a magnet. I think it would be more convenient to change it to a rotating coil." Edison replied.

"Very well, I will allocate a sum of money to you through the McDonald Venture Capital Bank to research this project. After success, you can also get a part of the patent income. What do you think?" Scrooge said hurriedly.

"Okay, thank you, Mr. MacDonald, you are so kind." Edison said gratefully.

"Perversion is perversion!" Scrooge thought in his heart, "This design change was completed by Siemens in the original history, and it was one of the things started by Siemens. I originally planned to spend a year or so. , I made it out. I didn’t expect that now, because he brought Edison to learn electromagnetics, he actually made out the concept of this design. Perversion is perversion. Fortunately, at least temporarily, he is still on our side. Perverted.” Scrooge thought.
