Daming Crazy Emperor

Chapter 632
Armed Forces City, in the grid city surrounded by curtains.

Taichang led a group of officials from the Ministry of Industry to stand under the latest hot air balloon, watching Cheng Jiashuo's performance.

At this moment, the blades of the fan have been installed on the fire-proof device in the middle, and a round frame surrounded by a thin copper skin is added to the periphery of the blades to gather the wind force to push it forward.

Cheng Jiashuo ordered people to carefully check the ropes below, and adjusted the flame of the kerosene lamp, and the huge hot air balloon slowly went up.

This time, the hot air balloon rose a foot high.

After the rope below was straightened, Cheng Jiashuo finely adjusted the kerosene lamp until he felt that the buoyancy was almost right, and then he ordered the strong man next to him to turn the handle to make the blades rotate.

There was a gust of "huh", and the hot air balloon circled around the wooden frame below.

This time, the rope below is longer, and the hot air balloon has a wider range of motion. Moreover, after the blades are installed on the fireproof device, the thrust seems to be much larger. The speed of the hot air balloon can already catch up with the speed of normal people walking. up.

Seeing this, Taichang couldn't help but asked with a smile: "Meng Hou, how about this hot air balloon?"

Hearing this, Bi Maokang couldn't help admiringly said: "Your Majesty is wise, I really didn't expect that His Majesty can really make people fly into the sky, and he can do it in such a short time."

What I said is a bit flattering.

Taichang smiled and shook his head and said: "I just came up with some ideas, and Yaoguang did it all. This kid is really capable."

Uh, the Ministry of Industry also has many capable people, but the emperor chose a minister of the Ministry of Commerce to develop this new thing that can fly into the sky.

Hearing this, Bi Maokang was somewhat embarrassed.

He looked at the capable generals around him, and then said cautiously: "Your Majesty, I dare you, next time you want to develop something new, can you let our Ministry of Industry try it, after all, our Ministry of Industry is responsible for these things .”

There are so many things I want to develop.

That's right, that's why I invited you here.

Taichang immediately waved his hand and said, "Okay, Yaoguang, let's get off first."

When Cheng Jiashuo heard this, he quickly told the strong man to stop shaking, then turned the flame of the kerosene lamp to the minimum, and let the hot air balloon slowly descend.

Taichang saw him coming down from the wooden frame, and waved to the crowd again: "Come on, let's go to Mizhi's place to have a look."

To be honest, all the officials of the Ministry of Industry did not understand why the emperor summoned them all of a sudden.

At present, the Ministry of Industry is responsible for a lot of things, such as building ships, railways, trains, bridges, steam machine tools, weapons and equipment, etc.

It can be said that each project is a huge project, and the manpower and material resources to be used are not ordinary, and the things to be managed are not ordinary.

Therefore, they are very busy all day long, and sometimes they don't even have time to rest.

These emperors should be clear!

If it's just to see something that can fly into the sky, there seems to be no need to call them all here.

Moreover, now that they have finished watching, what does the emperor want to take them to see?

Soon, they came to a grid city that had just been opened next to it.

There are no people in this city at all, and there are not many factories and courtyards where craftsmen live.

If it weren't for the smoke coming from the chimney of a factory building, they would have thought that there was no one there.

What is it doing here?
Taichang led everyone into the factory building to have a look, and everyone couldn't help being dumbfounded.

The inside of this factory building is also too simple, the main equipment is a few big pots, a few shelves and a few pulleys for taking up wires.

There are also coils of copper wire, rubber buckets, paint buckets, iron blocks, coal, and other messy things, piled up everywhere.

At the moment, several large pots are cooking, but what is boiled is not food, but what is inside the rubber and paint.

The taste was simply unbearable.

Taichang couldn't help frowning when he smelled it.

This kid Fang Yizhi is too obsessed with research, he doesn't care about the surrounding environment at all, and he doesn't know how to arrange the factory well.

Maybe it's the same with research.

He looked up and searched in the huge factory building for a while, only to find that this kid was working on a simple long table.

What is Fang Yizhi busy with?

Everyone followed Taichang lightly and walked over to take a look, and couldn't help being dumbfounded again.

Because they have no idea what this kid is up to.

On the table was a mess of copper wires and several wooden shelves, and Fang Yizhi was carefully stuffing things into a wooden box.

Taichang understood at a glance that this kid was making a simple voltmeter.

Because working with electricity is too dangerous, it’s fine if the voltage is lower, but if the voltage is higher, people will be killed every minute.

Therefore, you must first make something to measure the voltage.

The wooden box in front of Fang Yizhi is a simple voltmeter.

That is to say, there is a small iron block under a pointer, and there is a coil with copper wire near the small iron block.

Once the coil is energized, the small iron block will be attracted by the magnetic force. The higher the voltage, the greater the magnetic force, the greater the range of the small iron block will be attracted, and the swing of the pointer above will also increase accordingly. .

A simple voltmeter works like this.

Of course, it's not that easy to do.

Fang Yizhi worked for a long time before assembling the simple voltmeter.

Immediately afterwards, he raised his hand and opened a valve without hesitation.

A fan-like thing next to the table immediately spun rapidly.

However, this fan does not have blades. Its front end is a magnet, and a circle of copper wire is fixed around it.

This is a simple generator, which is modified with a fan.

The speed of the fan shaft driven by the steam piston is not so fast, and the voltage in the copper wire is not so high. With a soft snap, an iron nail hanging on a wooden frame is sucked by an iron rod with a coil. past.

This proves that there is electricity in the coil.

Seeing this, Fang Yizhi immediately picked up the two copper wires protruding from the simple electric meter, and was about to connect them to the coil.

Taichang hastily stretched out his hand to block him, and said seriously: "Mizhi, put on the rubber gloves first, how many times have I told you that electricity is very dangerous, much more dangerous than fire, you must be careful when you experiment Wear rubber gloves."

Uh.

The emperor is here!

Fang Yizhi hurriedly cupped his hands and said: "Your Majesty, the students remember what you said, but the rubber gloves are too obstructive to wear, so the students always forget."

After finishing speaking, he directly picked up two thick gloves from the stool next to him, held two copper wires and leaned towards the two sides of the coil.

These rubber gloves are actually very simple to make, that is, melt the raw rubber, then stuff two copper hand molds inside, and then take them up after they are covered with rubber. After cooling and drying, they are rubber gloves.

However, the rubber gloves produced in this way are not guaranteed to be beautiful, nor can they be used.

Probably Fang Yizhi was busy with experiments, but he just had two copper hand molds made randomly, and the rubber gloves made out of these were a bit bigger to wear, so he would feel that it was in the way.

Of course, this does not affect him holding two copper wires close to the two ends of the coil.

As soon as the two copper wires touched up, the pointer moved.

However, this pointer hit the bottom right away.

This proves that there is still a problem with the range or structure of the voltmeter.

Fang Yizhi put down the copper wire, turned off the valve, frowned and thought for a while, then unpacked the wooden box and started to work.

Seeing this, Taichang didn't say anything, just waved his hand, and walked out lightly with a group of officials from the Ministry of Industry.

After everyone came outside, Bi Maokang finally couldn't help asking: "Your Majesty, what is he developing?"

Taichang looked back at the messy factory building again, and then said solemnly: "What he studies is electricity. Electricity has many magical functions, such as driving motors. If motors can be developed, they will be much better than steam engines."

Uh, electricity, motor?

Hearing this, Bi Maokang couldn't help being confused.

He really couldn't imagine what electricity was and what this motor was.

Taichang then asked again: "How, what do you think when you see these?"

Uh, Weichen thinks you have some opinions on our Ministry of Industry!

You are looking for Cheng Jiashuo, the minister of the Ministry of Commerce, to develop the thing that flies into the sky.

This is to develop something more important than the steam engine, and what you are looking for is a candidate who has just finished the exam.

Are we doing something wrong?
Of course, Bi Maokang dared not say so.

He thought for a while, then carefully cupped his hands and said: "I am afraid, please ask the emperor to teach me."

what are you thinking?

Taichang said helplessly: "I'm just asking you, how do you feel when you see this simple factory building?"

Uh, that's what it meant.

Bi Maokang thought for a while, and then seriously said: "If this motor is really more important than a steam engine, then we should send more people to Fang Yizhi to help him, and at the same time tidy up the inside of the factory."

Is that right?

Taichang nodded slightly and said: "Yes, we should pay attention to talents and create a good environment for them so that they can concentrate on research, study hard, and strive to produce research results as soon as possible."
