The cicadas chirp in summer, making the weather even hotter.
Yu Qian raised his sleeves, wiped the sweat from his forehead, and stared at the instrument in front of him with Song Duanduan.
Suddenly, the pointer inside the instrument shook slightly.
"Moved!"
Yu Qian and Song Duanduan shouted in unison.
Then, the pointer shook again, this time the amplitude was obviously larger, but it quickly returned to its original position. Soon, the pointer shook again. This time the pointer not only deflected, but the amplitude of the deflection also increased little by little, and finally stabilized. At the position of the scale "3", after continuing for a period of time, the pointer seemed to have lost its support and returned to the original point.
Guo Jiale ran out of the underground laboratory and shouted from a dozen feet away: "How?"
Yu Qian and Song Duandan stood up and grinned.
Guo Jiale quickly ran over.
Song Duanduan said with great joy: "Brother Guo, you have accomplished something unprecedented and great!"
Yu Qian nodded and praised: "It is indeed worthy of the word great."
Guo Jiale laughed loudly and carefully picked up the instrument: "Whether it is great or not is a matter behind the scenes. It has nothing to do with our life and will not be discussed. But at scale 3?"
Yu Qian quickly said: "We're here."
Guo Jiale raised his brows slightly, pointed to the long wires laid on the ground, and said with a smile: "In this way, by extending the copper wires, we can indeed realize the transmission of electrical energy over a distance of 150 feet. When we make a 100-foot-long wire, we will Conduct a test, and if it still succeeds, we can ask the court to conduct a sixty-mile remote line laying and experiment."
Song Duanduan couldn't help but high-five and thought: "If it still succeeds at sixty miles, then it may succeed at three hundred, five hundred, thousand, or even ten thousand miles! Once this is done, history will be completely changed!"
Yu Qian looked at the two people and felt happy from the bottom of his heart.
For these experiments, the two worked together for two years. They finally produced tinned copper wires and successfully sealed them with rubber. They also completed the production of a hand-cranked electromagnetic induction instrument and the current induction pointer in front of them.
Although no one knows exactly how useful this thing is.
Imperial College research allows useless research, but if you want to get more financial support, you must explain the possible results of continued research, such as application scenarios and application value.
Guo Jiale doesn't know the application scenarios and value of electric energy, but he knows that this is a brand new field with fascinating mysteries. Guo Jiale hopes to gain the ability of lightning by creating electric energy and illuminate the world, but this research has not yet been completed. Without the slightest clue, the current limited electric energy cannot light anything at all, at least Guo Jiale has not done it yet.
But Guo Jiale finally found a reason to persuade the Imperial College.
Yu Qian remembered Guo Jiale's wild idea. He actually wanted to make twenty-six hand-operated electromagnetic induction instruments, and then lay out twenty-six wires to connect twenty-six current induction pointers. Each wire was set to a pinyin. Letters, when the pointer shakes, means that a letter is conveyed. In this way, language can be conveyed with the help of pinyin.
The Imperial College was shocked by this amazing idea. When Xu Huizu, who was attending classes at the Military Academy, heard about it, he immediately found Guo Jiale. After seeing the most primitive instruments, Xu Huizu said: "Just spend money. If you run out of money, go to the Imperial College for it." If the Imperial Academy didn’t have it, I asked the Ministry of War, the Ministry of Household Affairs and the Emperor to ask for it. If no one gave me money, I would. Even if I sell the Duke of Wei’s palace, I will continue to study it!”
Xu Huizu did not just say a few words. He informed the Ministry of War, the Fifth Army Governor's Office and a number of Dukes and Counts about the matter. He jointly signed a letter with more than 200 nobles, generals and officials and wrote to the court to list Guo Jiale's research as a top secret. And fully support it.
That was on February 18th, so a highly confidential "218" plan emerged. However, this highly confidential project needed to be carried out outside. It couldn't be kept secret. Guo Jiale didn't want to change places and was used to the basement of the Imperial College. .
So the Guozi Jianjiang College set up a rule, and there were "three prohibitions" on Guo Jiale's research. Without permission, no inquiries were allowed, no observations were allowed, and no reading of the literature was allowed.
files.
Yu Qian is a participant in the "218" project. He once proposed using glass to encapsulate copper wires. Although it was feasible, it was impossible to use and it accidentally broke...
The success of this plan laid the foundation for the transmission of remote messages.
Once the experiment of sixty miles or even farther is successful, then the Ming Dynasty will have a brand new channel for delivering messages, one that does not require eight hundred miles of express, no trains, no ships, and can be delivered in a very short time Spread the news far and wide.
This method of using electricity to transmit documents will greatly strengthen the court's control over local areas.
Just imagine, if Beijing's coal shortage is too large, all it takes is to send a telegram to Shanxi and ask it to transport coal in large quantities to alleviate the problem. If the Western Xinjiang Province received intelligence information from Timur's country, it could completely inform Beijing of the news via telegram, and Beijing would be able to respond with countermeasures in the shortest possible time. If there is a disaster in Fengyang Mansion, the court only needs to send telegrams to Zhejiang, Jiangxi, Henan, Shandong and other provinces to transport grain from different directions...
Of course, the most important thing is the military value. If someone wants to jump on the grassland, the chieftain from the southwest wants to eat gunpowder bombs, someone in Dingyuan province overturns the table, or Xijiang province needs activities, the court can do it in a very short time. Receive intelligence and make decisions within 10 days to more than a month.
This is an epoch-making invention and creation that changed the Ming Dynasty, and is well-deserved for its greatness!
Zhou Chang, the dean of the Craftsman Academy, came over, looked at the three happy people, and said with a smile: "It seems that the experiment was a success, which makes the three of you smile."
Guo Jiale, Song Duanduan, and Yu Qian saluted solemnly.
Zhou Chang looked at the instruments on the table, nodded and said: "Get better step by step, like a steam engine, it is still being iterated. Your electric energy is a new thing, and there is still a long way to go before it is practical. Again, the same sentence If so, just go ahead and do it, the Craftsman Academy will fully support you."
Guo Jiale thanked Zhou Chang and then said: "In the future, we need to unify the copper wire specifications, including length, to prepare for future laying."
Zhou Chang reached out and patted the instrument in front of him: "No problem, I will arrange for someone to do it according to the specifications. But I suggest that we go directly to the one-mile experiment instead of testing it over a hundred feet away."
"May I?"
Guo Jiale asked.
The experiments in the Imperial College were all carried out in small steps, and few made big strides. For example, Hu Qiyi flew into the sky with a hot air balloon. At the beginning, he started from three feet, ten feet, and twenty feet, and experimented upward little by little, and finally finally Flying is allowed.
Jogging in small increments is the basic principle of the experiment. If a large-scale advance fails, the losses will be huge.
Zhou Chang said: "Yes, I can make the decision on this matter."
Guo Jiale looked at Song Duanduan and Yu Qian.
Song Duanduan said in surprise: "If this is the case, the era of transmitting information via electrical energy will soon appear."
Zhou Chang turned around and waved his hand: "The copper wire is already being prepared. The experiment can be carried out in three days. The emperor and a group of military officers and nobles will visit. By the way, don't forget the meeting tomorrow morning."
Guo Jiale and others saluted Zhou Chang.
Yu Qian looked up at the sky and said softly: "We will have a meeting tomorrow. I heard that some people from the Second Artillery Bureau, the Science and Technology Bureau, and the Military War Bureau will also come, as well as the top supervisors from various colleges of the Imperial College."
Song Duanduan flicked his coat: "Not only that, Jinling Imperial College has also sent people. This meeting will be a genius meeting."
Guo Jiale untied the copper wire from the instrument port and said to Song Duanduan, who was about to collect the copper wire: "The term "genius's gathering" is indeed appropriate, but it's hard to say whether the gathering can produce a result. If so, what result? None, that would be a genius joke."
Yu Qian interjected: "The discussion may not produce results on the spot. No one can explain a certain sentence clearly, and inspiration may burst out."
Guo Jiale glared at Yu Qian: "You are a child, don't always be old-fashioned."
"Those who are close to red are red, what can I do..."
Yu Qian was helpless.
There are geniuses all around, except Zhu Wenkui who occasionally comes to the Imperial College
There are no people as old as me. Most of them are around thirty. The environment is calm and there is no innocence at all. Even if I wear a tiger head hat in winter, I will be laughed at. It’s easy...
Return to the basement.
Guo Jiale looked at the current-sensing pointer in front of him and said seriously: "Electric energy will attenuate to a certain extent as the distance increases. Although this attenuation is very inconspicuous at present, if the distance increases to hundreds or thousands of miles, This decay could become dire."
Song Duanduan nodded: "Judging from the shaking amplitude of the pointer, there is indeed some attenuation, but you have not found a way. You plan to make a larger hand-cranked power generation device to solve the attenuation by increasing the electric energy. . I believe that the increase in electric energy will definitely solve the attenuation problem, and transmission across thousands of miles is feasible."
Yu Qian tilted his head and asked: "When will the hand-cranked power generation be connected to the steam engine? If the steam engine drives the power generation, wouldn't the speed be faster? By then, I am looking forward to how high the electric energy intensity will be." "
Guo Jiale rubbed his sore arms: "Let the steam engine drive it, this is a feasible strategy. However, the emperor said that in the future, electric energy will replace the steam engine as a new energy. How to make electric drive drive propellers and wheels like a steam engine? , how did the movement appear..."
Song Duanduan and Yu Qian did not disturb Guo Jiale's meditation, but walked out of the basement.
The Imperial College is on summer vacation and is much quieter, but there are still a group of people who have not left, and these people are standing at the door of unknown knowledge.
Song Duanduan picked up the cattail fan and gave Yu Qian a few blows, and asked, "There is news that the second prince went to Tianjin Port. Is this true?"
