With Dorothea, it took several days for Scrooge to return to Cleveland from St. Paul. It was already late afternoon when they returned to Cleveland, so Scrooge took Dorothea home with him. After three days on the train, even an animal like Scrooge was quite tired, and Dorothea was even more exhausted. However, they managed to finish dinner with everyone and went to the nursery to see Scrooge's nephew and niece.

Strange to say, Donald, who was only a few months old and had not yet been weaned, did not recognize Scrooge at all, giggling with his mouth open when he saw him, and reached out to hug him. His sibling sister Dena, by contrast, was much more reserved, and although she looked at the strangers who suddenly appeared in front of them with wide eyes (Scrooge and Dorothea had appeared in front of them so rarely since they were born), she would turn her head aside and ignore them whenever Scrooge or Dorothea made a gesture that wanted to hug her. If they insist on hugging, well, our Miss Dena will prune her little mouth and cry in a majestic voice. At this time, Donald would also turn his head, first look at his sister curiously, and then cry with Denawawawa. So after a bit of scramble, well, Scrooge and Dorothea were expelled from the nursery.

"Why don't those children let me hold them, and they cry as soon as they please? I'm paying attention to the technique this time! The hand shape is absolutely right. Like a depressed child who didn't have access to a fun toy, Dorothea complained to Scrooge.

"Children are not familiar with you yet, and it will be different if they recognize you after a long time." Scrooge replied.

"But you don't know the child well, Donald will let you hug you!" Dorothea was upset and said, "It's not fair! ”

"Alright, Dorothea, don't be upset. Laugh a little. Scrooge said, "You can't be like a child, can you?" Well, you're tired today too. I'll take you back to your room. ”

Scrooge carried Dorothea to the door with a candlestick, and 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 tired too, go back and rest early." ”

"Well," said Scrooge, "good night, Dorothea. ”

"Good night!" Dorothea suddenly poked her head out of the room and looked into the hallway. Seeing that there was no one nearby, he suddenly kissed Scrooge lightly on the face like a dragonfly, and then jumped back to avoid Scrooge's embrace. Then he smiled at Scrooge and said, "Good night!" She gently closed the door in front of him.

"This little guy is getting more and more provocative......" Scrooge shook his head and walked downstairs to his room, passing by Anna's room, the door seemed to be closed tightly, and the light of a candle leaking through the crack in the door. Scrooge gave him a push, and the door opened, and Scrooge saw Anna sewing something under the candle. Hearing the sound of the door opening, she turned around and smiled softly at him when she saw that it was Scrooge.

"What are you doing?" Scrooge placed the candlestick in his hand on Anna's desk, which brightened the light around Anna.

"Make Donald and Dena a a new outfit. Autumn is coming. Anna replied without looking up, sewing finely.

"Why bother so hard, just buy a set." Scrooge said.

"It's better to buy it than to make it yourself. And I can't give the child anything, only ......," Anna whispered, the light of the candle shining on her face, a faint reddish glow.

"I saw you hugging Donald today, and I could see that he liked you very much." Anna said faintly.

"Hmm"

"Miss Dorothea is also a very nice person, and I can see that she also likes Donald and Miss Dena. And she loves you too. I can also see that you love her too. ”

"I love you too, Anna." Scrooge said, reaching out to shake Anna's hand.

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

……

Early the next morning, Scrooge rushed to the Dashi yàn room with a few retinues.

Edison and Mitchell had a dispute over the direction of the future power grid, especially motors and motors. The dispute is whether direct current or alternating current should be used.

It is said that in the original history, the "Ming King" Edison and the "Science Master" Tesla fought almost all their lives for this issue.

In the original history, Edison did his best to oppose Tesla's alternating current, and he relied on his academic hegemony to declare that Nikola Tesla was a major "heresy" in the scientific community, and his understanding of alternating current 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 invoked - it is said that Edison bribed some state government officials in the United States to change the local death penalty from hanging to alternating current in order to combat alternating current). But the alternating current does not kill people, and the prisoners are electrocuted into half death). Another theory is that Edison hired elementary school students to catch cats and dogs to use Tesla's alternating current to make a real thing, and electrocuted the cats and dogs to show the danger of Tesla's alternating current, so as to hit Tesla's alternating current status in people's minds. At the same time, he also constantly promoted that direct current is more efficient, safer and easier to use than alternating current.

Because of this history, when Scrooge knew that in the Dashi yàn room, people had a dispute over whether direct current or alternating current should be used, and Scrooge directly reflected that it must be Edison, a kid, who was against alternating current.

Scrooge knew that direct current did have many advantages, but in contrast, one advantage of alternating current was that direct current could not be compared to it in any way. That is, alternating current can pass through a guò transformer to obtain a relatively high voltage. In the process of long-distance power transmission, the higher the voltage of the wire with the same resistance, the less loss during the transmission process. In the future Rabbit Country, with this unique 1oo kilovolt ultra-high voltage transmission network, it is economically possible to transfer thousands of kilometers across regional stores, and even make this energy transmission economically cheaper than using heavy-haul trains to transport coal. It has given extremely strong support to the country's economic construction. And if direct current is used, without the help of transformers, well, historically, before the Tesla Ming alternating current transformer, Edison's direct current could only be sent a little more than a kilometer at most. In a big industrial city, every other kilometer, you have to build a power plant. This approach, in the eyes of Scrooge, who is accustomed to seeing large, large power plants, is simply intolerably inefficient.

"Edison is far from the prestige he had later, and he certainly wouldn't be as stubborn as he was later. It shouldn't be hard to convince him. On the carriage to the Dashi yàn room, Scrooge thought.

However, when he arrived at the place, Scrooge realized that he was completely wrong, and it was not Edison who strongly opposed alternating current, but Mitchell's group of Europeans, and one strongly supported alternating current, but Edison, who had been slandering alternating current all his life in the original calendar.

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

In its original history, before Tesla came up with his alternating current gadget, Edison had already obtained a whole bunch of patents related to direct current. These patents brought huge benefits to Edison's business, and he also invested too much money and energy in related research. At this time, of course, he didn't want something to jump out to change this qiē. At this time, Tesla, a genius who only had scientific and technical "right" in his head, but knew nothing about the economy, was among his employees, and he was bent on what kind of alternating current he wanted. Edison didn't suppress him, that's what's wrong.

Now, however, the situation is completely different, and since the development of shortwave stations, Edison's cousin has become more and more prominent, and there is a tendency to overwhelm Mitchell, the head of the original radio station program. A group of American technicians who were the same as Edison, who were worse than Europeans, who got less money than Europeans, who were more similar in style to Edison, and who relied more on inspiration and intuition to work, united around Edison and formed an American gang. And those Cobain-born Europeans unwittingly rallied around Mitchell and formed a European gang (in fact, they even tried to bring Maxwell in at one point, but failed because Maxwell didn't pay much attention to things like technology).

"This is really, 'where there are people, there are rivers and lakes, and where there are rivers and lakes, there are disputes', well, who said that? It seems that Ouyang Feng said it. Scrooge couldn't help but think of a certain movie he had watched in his previous life, "Ouyang Feng's words have a little truth, but they are too literate and crepe." It's better to just say, 'The ass is bigger than the head, and the ass determines the head'. Now Edison's interests are not tied to direct current, and it is actually normal for him to have such a position. In fact, think about it, historically, when Edison was desperately denigrating alternating current, as a master of playing with electricity, didn't he really know that alternating current had an advantage over direct current? How is this possible? Edison wasn't really a pig braincase. To put it bluntly, it's actually a matter of the ass. ”
