Ming Dynasty: Tanks blocked the door and you said to me, "Long live Ming Dynasty"

Wei Jinyu also bowed slightly to express his gratitude.

Zhu Youxiao looked at the parts on the table and continued speaking.

"Now I have seen the telegraph machine run successfully. Congratulations to Professor Wei!"

"This telegraph machine will be fully promoted in the Ming Dynasty in the future. I need to know more details."

Wei Jinyu said seriously: "Please ask, Dean, I will tell you everything I know!"

Zhu Youxiao asked, "What materials are used for the entire telegraph transmission and reception system? What is the total cost?"

Upon hearing this, Wei Jinyu pointed to a glass jar on the table that was 30 cm in diameter and 60 cm high and said:

"Please look, Dean. This is an accumulator."

Zhu Youxiao felt a little awkward and said, "From now on, you can call this a battery!"

"Yes, Dean, this battery is the most expensive of all the components."

Wei Jinyu continued, "There are ten sets of battery cells in it, each of which is made up of silver plates, white lead plates, and cotton cloth soaked in salt water."

"So, the cost of this battery alone is ten taels of silver!"

Wen Tiren couldn't help but be surprised: "Ten taels of silver for just this thing!"

Wei Jinyu glanced at him and said, "Sir, I just said that there are silver plates inside. Although they are not thick, they are not small, and there are exactly ten of them."

"So, including all other materials, the cost of this battery is ten taels, which is actually not that much."

Zhu Youxiao replied, "Ten taels is not expensive, where does this electricity come from?"

Wei Jinyu seemed to have been prepared. Upon hearing this, he took out a machine from under the table.

When Zhu Youxiao took a look, he saw a wheel as big as a bicycle tire with a handle, and the axle was connected to another small rotating shaft by a belt.

The small rotating shaft is connected to two large magnetic rings stuck together, which are surrounded by densely packed copper coils.

When he saw this thing, he exclaimed, "Wow!"

Isn't this a hand-cranked generator?

Last time, he just gave a hint, but he didn't expect Wei Jinyu to figure it out so quickly. The wisdom of the ancients is really amazing!

Wei Jinyu said, "This is an electric appliance. Connect the increase and decrease wires of the battery, and shake the handle to charge the battery."

"Is this thing so magical? It can actually generate electricity!"

Prince Xin was so surprised when he heard this that he could not help but step forward, grab the handle and start shaking it.

Wei Jinyu was a little speechless when he saw this: "Your Highness Prince Xin..."

Zhu Youxiao smiled and said, "Let him do whatever he wants."

When Wei Jinyu heard that the emperor had no objection and saw Prince Xin shaking the bicycle very hard, he suddenly felt that it would be a waste not to charge the battery.

So she connected the two wires of the generator to the two ends of the battery while speaking.

"Your Highness Prince Xin has great arm strength. He is truly an expert at creating electricity!"

"Hehe, I can create electricity! I am now the God of Thunder!" Prince Xin became more and more excited as he shook his head.

When Wen Tiren saw him like this, he couldn't help but stroke his beard.

It’s great to be young, you have so much energy!

Zhu Youxiao did not stop him.

Let the little brother make some noise. He won’t jump so much when he’s tired.

He continued to look at Wei Jinyu: "This electrical appliance will be called a generator in the future."

Wei Jinyu: "I'll listen to the dean in everything. The generator sounds really good!"

Zhu Youxiao continued to ask: "How long does it take to fully charge this battery, and how long can it be used?"

Wei Jinyu answered without hesitation: "It takes half an hour to fully charge each time, and it can power a telegraph for half a day."

Zhu Youxiao couldn't help but laugh when he heard this: "Charging for 25 minutes, and standby for 5 hours, not bad, quite good!"

Wei Jinyu was stunned.

Is this the emperor's hint that he should improve charging efficiency?

In fact, she had no idea that Zhu Youxiao was just remembering an advertising slogan from his previous life.

At this time, Bo Jue and Sun Yuanhua had also gathered around the batteries and generators to observe them carefully.

If they hadn't come with Zhu Youxiao on this trip, they wouldn't have known what Wei Jinyu was researching all day.

They had seen the idea of ​​creating electricity when reading ancient books before, but seeing it with their own eyes was still quite novel.

When Prince Xin saw that there were audiences, he shook the piano even harder, and the handle was almost sparked by him.

Zhu Youxiao continued to talk about telegraph machines with Wei Jinyu.

"Dean, this telegraph now uses a common antenna for both sending and receiving messages, but it cannot be operated at the same time unless two separate antennas are installed."

Zhu Youxiao looked at the two radio transmitter parts that looked like large suitcases.

One of them was connected to a key, an inductor, a spark ball and an antenna by wires. He knew it was a telegraph machine at first glance.

Needless to say, the other one is the telegraph receiver, which is connected to the antenna, machine, mineral and sound-receiving device.

Zhu Youxiao asked: "How much does this whole set of telegraph machines cost?"

Wei Jinyu thought for a moment and said, "The telegraph machine is three taels, the generator is two taels, plus the battery is ten taels, the total cost is fifteen taels of silver."

Zhu Youxiao touched his chin and rolled his eyes.

"Fifteen taels, yeah, this cost is not bad."

In fact, he was calculating in his mind how much would be appropriate to sell one of the Ministry of Revenue to Guo Laokou when he returned.

After thinking for a while, he asked again: "What is the maximum distance of telegraph communication now?"

Wei Jinyu was ashamed when she heard this: "I am ashamed. The communication distance of this telegraph cannot reach the 200 miles that the dean said. The farthest I have tried so far is only 20 miles."

Seeing this, Zhu Youxiao couldn't help but encourage him: "It's okay, the two hundred miles I mentioned before is just a target."

"Try some new materials and new methods in the future. I believe you will soon reach a distance of 200 miles or even beyond!"

In fact, he could understand it very well. With the current technical conditions, a communication range of several dozen miles is enough.

"Thank you for your encouragement, Dean!" Wei Jinyu became excited again after hearing that.

By this time, Prince Xin had been rowing for a while and was extremely tired. He no longer had the cheerful mood he had before, so he simply dropped the pole and sat on the ground complaining.

"Are you kidding me? I shook the rock for a long time, but there was no lightning or thunder!"

"Where does the electricity come from? Where does the electricity come from?"

Seeing him like this, Zhu Youxiao directly found two electric wires.

Upon closer inspection, the wires are all copper cores, with a layer of peach gum cotton cloth coated on the outside for insulation.

He connected the two wires to the two poles of the battery, and then gave Prince Xin a loving smile.

But in the next second, the other end of the wire was pushed against Prince Xin's buttocks...

Chapter 468 The first snow of the eighth year of Tianqi came earlier than usual

Prince Xin suddenly felt a sharp pain in his buttocks, his scalp went numb, and he even had the illusion that his soul and body were separated.

"Ouch!!!!!"

He let out a scream and bounced up from the spot.

I felt a burning sensation in my buttocks, and my entire thigh went numb, and my voice began to twitch.

Wei Jinyu couldn't help but cover his mouth and laugh at the funny look.

But Prince Xin turned around and looked at Zhu Youxiao with resentment in his eyes.

"Royal brother...if you want to kill me, just say it directly. Why torture me like this..."

Zhu Youxiao held the electric wire in his hand, his smile still lingering.

"Hey, my prince, didn't you just say you wanted electricity? I am doing this at your request."

Upon hearing this, the resentment in Prince Xin's eyes disappeared instantly. He became playful and stared curiously at the wire in Zhu Youxiao's hand.

"Really? The electricity that hit my butt just now was actually created by me! Was it released from this wire?"

Seeing Zhu Youxiao nod, he directly snatched the wire and looked at Wen Tiren next to him with an evil look on his face.

When Wen Tiren thought of the scream he had just heard, his heart trembled and he quickly hid behind Zhu Youxiao.

"Your Majesty, please save me!"

Prince Xin was displeased: "Lord Wen, this is not very nice of you. As the saying goes, we should share the hardship and the shock, right?"

Before Zhu Youxiao could speak, Sun Yuanhua had already stepped forward and said, "Your Highness Prince Xin, if you don't mind, why not send me a call?"

He was really curious and wanted to experience the feeling of artificial electricity himself.

Seeing this, Zhu Youxiao couldn't help but give him a thumbs up.

As expected of a scientific research maniac, there is only one word to describe himself: ruthless!

When Prince Xin saw someone volunteering, he was overjoyed.

"Old Wen, you can't do this! Look at how conscious Dean Sun is, learn from him!"

Wen Tiren just curled his lips.

What is the purpose of this official learning?

I only serve Your Majesty. I will not compromise myself for anyone else except Your Majesty.

Prince Xin had already left him aside and turned to Sun Yuanhua with excitement.

"President Sun, you asked for this on your own initiative. If anything goes wrong, you can't blame me!"

"It's okay. I should be able to handle it." He said and stretched out his hand seriously.

Prince Xin placed the copper cores of the two wires directly on his palm with an expectant look on his face.

Sun Yuanhua suddenly felt a stinging pain in his palm, mixed with bursts of burning and numbness.

He couldn't help but twitching his lips twice, but didn't say a word.

Soon he got used to it, closed his eyes, and carefully felt the wonderful feeling of electric shock.

Prince Xin couldn't help but frown upon seeing this.

"Dean Sun, your reaction...is wrong!"

As he spoke, he pulled the wire back and forth, then pressed it against his palm with a puzzled look on his face.

"what!!!"

He screamed, grimaced in pain, and quickly threw the wire away.

"Dean Sun, you cheated me! It hurts me so much!"

Sun Yuanhua looked innocent.

"Your Highness, it doesn't seem to hurt that much..."

Seeing them like this, Zhu Youxiao finally spoke up: "My brother, you may have wrongly blamed Dean Sun. Everyone's inductance is different, and the conductivity of the body is also different."

He still remembered that in his previous life there was a great man who could use his palms to fry fish with electricity. How awesome!

But most people are still easily injured by electric shock.

That is to say, the voltage of the battery is not enough to be fatal, so he dares to let Prince Xin play with it.

The few of them were having a lot of fun, but Zhu Youxiao discovered that Bo Jue, the dean of Mozi Academy, was sitting in a daze with his chin in his hand.

He couldn't help but walk over and asked curiously.

"Dean Bo, what are you thinking about? You look so absorbed in it."

Bo Jue came back to his senses and quickly bowed and said:

"Dean, I was thinking that now that Professor Wei has built this telegraph, we can communicate with people dozens of miles away."
