Daming Crazy Emperor

Chapter 659 Telegram
The Ming Dynasty expedition fleet is about to set off, but Taichang seems to have endless things to do.

No way, he had no plans to go to America in the near future. Now the army of Shenji Battalion and Shenwu Battalion are going on an expedition outside the Great Wall.

If it wasn't for Carinho who suddenly ran over and told him the movement of the anti-Habsburg alliance, he wouldn't be in such a hurry to go out.

Other things are fine, but he has to take care of the steam engine acquired by several countries of the anti-Habsburg alliance.

He had to hurry up and block people's way of obtaining resources. If he really let it go, let the European countries use the steam engine technology to develop crazily. In a few years, people probably would build steam machine tools and ships.

At that time, Da Ming would have to pay a heavy price if he wanted to clean up the family.

Therefore, he could only hastily set off to the Americas to block people's access to resources.

He is really a bit busy right now, and he has to make arrangements for many things before he can set off with confidence.

After Xu Guangqi, chief assistant of the cabinet, and Nan Juyi, minister of the Ministry of War, left, he summoned Song Yingxing, Fang Yizhi and other heads of the research institute to the imperial ship.

After everyone arrived, he directly said: "Everyone, I must rush to America as soon as possible, and this time I may stay there for a long time. I can only roughly set the research projects for you. What's the problem? , you can write a letter and send someone to America, and I will give you a detailed answer."

Hearing the words, the heads of the research institutes were all helpless.

To be honest, the emperor's point is really very important to them. Many times, a word from the emperor can replace their hard work for days or even months.

The problem is that the emperor is the king of a country, and there are so many things to deal with, it is impossible to always accompany them to study and remind them all the time.

Alas, no way.

Song Yingxing said with some reluctance: "Your Majesty, how long do you think it will take you to come back?"

Uh, this is really hard to say.

Who knows how the situation in Europe will develop.

Taichang could only shake his head and sighed: "I can't say well about this. In short, if you encounter problems that you really can't solve, please write. I will definitely reply to you as soon as possible."

Speaking of this communication, telegram is naturally the fastest way of communication at the moment.

Just in time, if we want to arrange a research project for them, let's start with this telegram.

Thinking of this, Taichang directly asked: "Secret, how is the coding of the telegram?"

Hearing the words, Fang Yizhi quickly took out a book from his arms, handed it to Taichang respectfully, and then explained: "Your Majesty, this is the code made by my minister according to the "Thousand Characters", but the total is only [-] characters. A thousand words, I don’t know if it’s enough.”

Hearing this, Taichang took a look at the coding book and couldn't help showing excitement.

"Thousand Characters" originally used a summary of commonly used characters, but there are not as many commonly used characters at this time as later generations. I believe that with this code, most things can be communicated by telegram.

He couldn't help but nodded and said: "Very good, we can use this code to communicate first.

Now there is no problem in laying telegraph lines on land. After you make a high-power motor, you can lay telegraph lines in the direction of the Americas. "

Immediately afterwards, he pointed to the map and said: "You can first lay the line from the capital to the north to Liaodong, then from Liaodong to the southernmost tip of the vassal Korea, and then from the southwest end of Honshu Island to Wenguo Gongfu to the south, and then pass through the entire Wenguo Mansion to the vicinity of the archipelago in the north.

In addition, you can also order people to lay telegraph lines from the end of the northern archipelago in North America to the capital of Eastern Yin, and then from the capital of Eastern Yin to New Tongzhou City and New Liaoyang City.

In this way, the communication time on land can be shortened to one day, and it only takes more than ten days at sea to reach the capital of Western Yin. "

In this way, the transmission speed will be much faster.

If the letter is sent by sea by express boat, it will take at least three or four months to send the letter from the capital to the capital of Western Yin!
Unexpectedly, Fang Yizhi still had something to say: "Your Majesty, didn't you say that lines can be laid under the sea? If we lay the lines under the sea, wouldn't the communication time be shortened to one day?"

Uh, if there is not enough protective layer, you lay the line to the bottom of the sea, isn't that the electric fish?
Taichang could only seriously explain: "Mizhi, don't lay this submarine line indiscriminately, if there is not enough protective layer, it will be a waste of time.

Because once the wire sheath is damaged, the metal wire will be connected to the sea water.

The seabed is complicated, and the line skin is easy to be damaged.

For example, the undercurrent at the bottom of the sea pushes the wire to the sharp stone, or a very hungry fish catches the wire and bites it, etc., which may cause the wire sheath to be damaged.

Once the wire sheath is damaged, no matter how powerful the motor is, it will be useless.

Because after the metal wire is connected to the seawater, all the electric energy is consumed in the seawater, and the signal cannot be transmitted at all. "

Uh, this.

Hearing this, Fang Yizhi said in embarrassment: "Your Majesty, how can we ensure that the thread is not damaged?"

This difficulty is a bit bigger.

Taichang simply asked Shen Yunpei: "Jun Hou, when do you think the plastic can be extracted."

Shen Yunpei heard the words, and quickly replied: "Your Majesty, I have already made a small sealing device, and the effect seems to be okay, but the separated things have to be tested in every way, and the large sealing device also needs a certain amount of time to build. We estimate that it will take at least two or three months to mass-produce the plastic you mentioned."

You kid didn't say it earlier.

Taichang couldn't help but said excitedly: "It would be easier if there were plastics.

Secretly, in two or three months, you can lay land lines and trial-produce submarine cables at the same time.

The so-called cable is to wrap a single wire with a protective layer, then combine several wires together, and then wrap one or more layers of protective layers outside.

The protection requirements of submarine cables are relatively high. You can first wrap a layer of plastic on the outside of the wire, then combine the four wires together, then wrap a thick layer of plastic on the outside, then wrap a layer of copper, and finally Wrap a thick layer of rubber on the outside of the copper skin.

This requires the design of many special machine tools to cover it layer by layer. You can ask Liangfu about the machine tools. "

My God, this submarine cable is really not an ordinary trouble, it has to be wrapped with four layers of protection.

However, those who are really obsessed with research are really not afraid of trouble.

Fang Yizhi cupped his hands without hesitation and said, "I understand."

Taichang nodded slightly, and then solemnly said: "The project that Mizhi and Junhou are responsible for is the most important at this stage. If you have time, you can help them. As long as the telegraph line can be laid to the capital of Western Yin, our communication will be convenient. gone."

When everyone heard the words, they nodded quickly and said, "I understand."

Immediately afterwards, Taichang explained in detail: "The projects that other people are in charge of should also have a focus.

Chang Geng, you should study how to smelt aluminum as soon as possible. This metal material has great uses.

Yoshiho, your focus is on the development of large steam engines first, because our ships need to be speeded up.

Chuyang, you can first focus on increasing the rate of fire of guns and artillery, because we are still far ahead of European countries in terms of range, and it will not happen overnight to improve the power of bullets and shells.

Yaoguang, your task in this section is to make the hot air balloon carry more than ten people, and the speed must at least catch up with the infantry fighting vehicle.

Bo Gong, you start with a small boat and study how to increase the speed of the ship. The speed of this ship is not only related to power, but also related to the resistance of the water. As for how to minimize the resistance of the water, you can refer to the thermal design of Yaoguang Balloon, boat bottom and hull are designed as imitative shuttle type as far as possible. "

He said a lot in one breath, and most people would probably be in a cloud of fog after hearing it, and have no idea what he was talking about.

A group of people in charge of the research nodded thoughtfully after hearing this, and then they all cupped their hands and said: "I understand."
