1855 United States Tycoon

With Dorothea, it took several days before Scrooge drove back to Cleveland from Sao Paulo. It was early evening when they returned to Cleveland, so Scrooge took Dorothea home directly. After being on the train for three days, even for animals like Scrooge, they were quite tired, and Dorothea was even more tired. But they still supported Scrooge's nephew and niece after having dinner with everyone.

Strangely enough, Donald, who was only a few months old and hadn't been weaned, didn't recognize Scrooge at all. When he saw him, he opened his mouth and giggled, and stretched out his hand to hug him. In contrast, his compatriot Big Si Dena is much more reserved. Although she also opened her eyes and looked curiously at the stranger who suddenly appeared in front of them, as long as Scrooge or Dorothea made one If she wanted to hug her, she would turn her head aside and ignore them. If they insist on hugging, um, our Dena Miss will squat her mouth, and cry with a magnificent voice. At this time, Donald will also turn his head, first look at Big sis curiously, and then follow Dena to cry. So after a rush, well, Scrooge and Dorothea were expelled from the nursery.

"Why, those children didn't let me hold them, so they cried? I paid attention to the technique this time! The shape of the hand is absolutely correct." Like a child who was depressed without playing any fun toys, Dorothea turned towards Scrooge complained.

"The child is not familiar with you. It will be different if they recognize you after a long time." Scrooge replied.

"But if you don't know the child well, Donald will let you hold it!" Dorothea said unhappily, "It's not fair!"

"Okay, Dorothea, don't be upset. Smile." Scrooge said, "I can't be familiar with children, right? Well, you are tired today. I will send you back to the room. "

Scrooge held the candlestick and brought Dorothea to the door of the room. Dorothea opened the door and Scrooge went in with her and helped her light the candle on the table. Dorothea sent Scrooge to the door and said to Scrooge: "You are also very tired. Go back and rest early."

"All right, then," Scrooge said. "Good night, Dorothea."

"Good night!" Dorothea stuck her head out of the room suddenly and looked into the corridor. Seeing no one nearby, he suddenly kissed Scrooge gently on the face like a dragonfly, and then jumped back and escaped Scrooge's hug. Then he smiled at Scrooge and said, "Good night!" He gently closed the door in front of him.

"This little guy is getting more and more cute..." Scrooge shook his head and walked towards the own room downstairs. On the way, he passed Anna's room. The door seemed to be unclosed, and there was still the light of candles. Leaked through the crack in the door. Scrooge pushed it smoothly and the door opened. Scrooge saw what Anna was sewing under the candle. Hearing the sound of the door opening, she turned her head and saw that it was Scrooge, and smiled softly at him.

"What are you doing?" Scrooge put the candlestick in his hand on Anna's table, which brightened the light around Anna a lot.

"Make a new set of clothes for Donald and Dena. Autumn is almost here." Anna didn't look up, she replied while sewing carefully.

"Why so hard? Just buy a set." Scrooge said.

"It's not as good as making it by myself. And I can't give the child anything, I can only..." Anna whispered, the light of the candle shone a faint reddish light on her face.

"Seeing you holding Donald today, I can see that he likes you very much." Anna said quietly.

"Um"

"Dorothea Miss is also a very good person. I can see that she also likes Donald and Dana Miss. And she loves you very much. I can see that you love her too."

"I love you too, Anna." Scrooge said, reaching out to hold Anna's hand at the same time.

"No, Scrooge, it's different, I understand..." Anna said.

Early the next morning, Scrooge rushed to the large laboratory with several entourages.

Edison and Mitchell had a dispute about the future development direction of the power grid, especially the motor and generator. The dispute is whether to use direct current or alternating current.

It is said that in the original history, "Invention King" Edison and "Science Master" Tesla have been fighting for this issue for almost their entire lives.

In the original history, Edison did his best to oppose Tesla's alternating current. With his own academic dominance, he claimed that Nikola Tesla was a major "heresy" in the scientific world. The alternating current he invented directly affected the safety of human life. , And repeatedly showed how dogs and cats died instantly after passing alternating current. (The "electric chair" death penalty was also inspired by this. It is said that in order to combat alternating current, Edison bought some United States state government officials and changed the local death penalty from hanging to alternating current electrocution. Alternating current is available. Electricity does not kill people, and all prisoners are electrocuted to half death). Another said that Edison hired elementary school students to catch cats and dogs to use Tesla's alternating current to do experiments, and electrocuted the cats and dogs to show the harm of Tesla's alternating current, in order to combat Tesla's alternating current status in people's minds. At the same time, he continues to promote that direct current is more efficient, safer and easier to use than alternating current.

Because of this history, when Scrooge knew that in a large laboratory, people had disputes over whether to use direct current or alternating current, Scrooge directly reflected that it must be the kid Edison who was against alternating current again.

Scrooge knew that direct current does have many advantages, but in contrast, one advantage of alternating current is that direct current is incomparable anyway. That is, alternating current can obtain a relatively high voltage through a transformer. In the process of long-distance power transmission, using wires with the same resistance, the higher the voltage, the smaller the loss during the transmission process. In the later rabbit country, with the unique 1000 kV UHV transmission grid in the world, it is economically possible to deploy in inter-regional stores spanning thousands of kilometers, and even make this energy transmission more economical than using heavy-duty trains to transport coal. It's cheaper. Extremely powerful support for the country's economic construction. And if you use direct current without the help of a transformer, well, in history, before Tesla invented the alternating current transformer, Edison's direct current could only send a little more than one kilometer at most. In a large industrial city, you have to build a power plant every one kilometer. This approach, in the view of Shi Gaozhi, who is used to seeing large and super large power plants, is simply unbearable inefficiency.

"Now Edison is far from the prestige that he did later, and naturally he won't be as stubborn as he was later. It shouldn't be difficult to convince him." Scrooge thought in the carriage to the big laboratory.

However, when he got there, Scrooge realized that he was completely wrong. It was not Edison who kept opposing AC power, but the group of Europeans from Mitchell. Those who kept supporting AC power were doing their best in the original calendar. Edison slandered the AC for a lifetime.

"What's going on?" Scrooge was taken aback, but then he immediately figured out the reason. The reason was simple. It was just a butt problem.

In the original history, Edison had obtained a lot of patents related to direct current before Tesla came up with his set of AC power gadgets. These patents have brought huge benefits to Edison's enterprise, and he has also invested too much money and energy in related research. At this time, denying direct current to alternating current is simply wiping his own neck. At this time, he certainly didn't want something to pop out to change everything. At this time, his employees had a genius like Tesla, who was full of science and technology, but didn't know anything about the economy. He wanted to use AC power. Edison didn't suppress him, that's what's wrong.

But now, the situation is completely different. Starting from the development of shortwave radio, Edison's performance has become more and more prominent, and he has a tendency to overwhelm Mitchell, who was in charge of the original radio station plan. A group of United States technology personnel who are the same as Edison, who are worse than Europeans on the basis, get less money than Europeans, are more similar to Edison in style, and work more on inspiration and intuition. They unite spontaneously. Around Edison, a United States gang was formed. And those Europeans who were born in Cobain unknowingly united with Mitchell and formed a European gang (in fact, they even wanted to bring in Maxwell at one time, but because Maxwell was not concerned about technology and other things Not very concerned, but failed).

"This is really,'Where there are people, there are Rivers and Lakes, and where there are Rivers and Lakes, there are disputes', um, who said this? It seems to be Ouyang Feng." Shi Gaozhi couldn't help but think of his previous life. I’ve watched a movie, “Ouyang Feng’s words make sense, but they’re too literary and literary. It’s better to just say, “The butt is bigger than the head, and the butt determines the head.” Now Edison’s interests are not. It’s normal for him to have such a position without being tied to direct current. In fact, think about it, in history, when Edison desperately discredited alternating current, as a master of electric power, he really didn’t know that, Is alternating current more advantageous than direct current? How is this possible? Edison is not a real pig head. To put it bluntly, it's actually a butt problem."
