Mr. Ai applauded again and again, staring at the drawings drawn by Gao Yiming, and couldn't extricate himself.

"If such a section of the river is not easy to find, we can also build a dam in a place with few people, to artificially increase the potential energy of water, of course, if there is too much electricity to be wasted, we can study storage devices and long-distance transmission lines, of course, if you want to transmit electricity over long distances, you must solve the problem of electricity attenuation, which requires the use of another artifact, transformer."

Then Gao Yiming told them about the working principle of the transformer, which laid the foundation for the rapid development of Daming power in the future. However, Gao Yiming didn't think so much about it at this time, he only thought about when the college could really develop the battery, then he could see electric cars running all over the world, at that time, it was not far from life in the 21st century, and he was looking forward to it.

Gao Yiming said quickly, Mr. Ai remembered not slowly, and he asked Gao Yiming to correct the inaccurate places, and then he looked at it like life, reluctant to put it down, and at the same time began to discuss with the students the feasibility of building this kind of power generation device, after all, the generator power generation driven by the water turbine really made him dissatisfied.

Coming out of the power generation room, Gao Yiming came to the train research laboratory of the college again, where the two developed locomotives were located, and now the laboratory is waiting for the carriage and rails to be completed in the factory, and the test can begin.

Due to the lack of available paint, the locomotive retains the original color of iron, in order to increase the anti-corrosion and the service life of the locomotive, the academy under Gao Yiming's suggestion, with strong acid to blunt the surface of the train, it looks like this iron armor is majestic and exudes a dark light, looking ancient and heavy.

In order to let Gao Yiming understand, the students started the train on the spot, and the steam from the train made Gao Yiming and Cai Dafa, who had no time to get out of the factory, suddenly become soup chickens.

"This train is steaming." Gao Yiming looked at the train in front of him that could only keep turning in circles in the yard, like a trapped dragon, and the piercing sound indicated its desire to rush in the wilderness.

"Yes, Dean, this thing has a lot of strength, and dozens of cows can't pull it." Cai Dafa proudly said that this is definitely the most brilliant invention of the college.

Using a cow to test the power of the locomotive, I don't know who invented such a strange idea, Gao Yiming looked at Cai Dafa strangely, which made him a little uncomfortable.

"Is there anything wrong with the subordinates?"

"That's not it, now the rails and train cars available in the factory are ready, and the first railway can be built in the spring after the year, and then the students of the college should actively participate in it, summarize the entire train system, and form a set of standards, so that it can be better promoted throughout the country, you know?"

"Yes! Please rest assured that the teachers and students of the academy have begun to do these things, and these are all listed as top secrets by the academy. ”

"That's good, once the train appears in front of the world, I believe it will immediately cause a lot of movement, and then it will become a key place for secret agents of other countries to break through, and the secrecy work cannot be relaxed, and we do not seek to be able to keep it secret forever, but we must be at least twenty to thirty years ahead."

"Yes! The subordinates will rest assured that they will definitely live up to the dean's expectations. ”

In the academy was busy until the evening, looking at the street lights installed in the college, alternating between bright and dark in the dark night, Gao Yiming decisively broke off the idea of installing electric lights in the palace, or wait for the lights to stabilize before talking, so he found Mr. Ai and his students again, and told him the method of alternating current and direct current conversion, as for the voltage regulator, Gao Yiming didn't understand it, only told Mr. Ai how that thing worked, and before the voltage regulator came out, they could only let them use direct current first.

In addition, the miniaturization of light bulbs has a long way to go.

Coming out of Daming Academy, the sky was already full of stars.

Stretching his waist, Gao Yiming came to the arsenal again, where there is no rest for 24 hours now

The four-six work system, the assembly line is constantly assembling infantry combat vehicles, and now there are as many as 50 vehicles sent to the front line, which depends on the standardization that Gao Yiming asked them to implement.

After inspecting the arsenal and returning to the palace, seeing that the night was good, Gao Yiming asked the guards who had been with him for a day to go back to rest on their own, and walked alone in the square of the Fengtian Temple, inhaling some cold air, which made the Lingtai a lot clearer.

The snow on the square has not been cleaned by the palace in accordance with Gao Yiming's orders over the years, but some roads have been cleared after each snowfall.

Looking at the bright moon hanging in the sky, he felt a little poetic, but after holding it for a long time, he didn't hold it back, at this time, it was like constipation, frowning and standing there thinking and meditating, he didn't even know that he would come over in a week.
