After the Shangyuan Festival, Zhu Jianji, as the prince of the Ming Dynasty, consciously stood up to help the cheap father share the pressure and deal with the arrival of vassal kings and foreign kings and envoys from all over the country.

It can also be regarded as an early adaptation to the life of a king.

Eating and drinking are indispensable.

During this period of time, life was extremely depressed, and he was drunk and dreaming of death with the powerful almost every day, but Zhu Jianji was smarter than the kings of the old Zhu family, whether it was a foreign country or a vassal king, the value of what Zhu Jianji rewarded back would never exceed their tribute.

In a word, courtesy is still exchanged.

Don't try to make money from Daming.

If Lao Tzu doesn't make your money, you should burn high incense.

Finally, when the foreign envoys and kings were gone, and the local vassal kings returned to their respective domains, Zhu Jianji had time to busy himself with his own affairs.

Zhao Chuanjia and Zhu Bi sent back the news from the Leizhou Peninsula.

According to the letter report, Zhu Jianji thought that the magnet should be successfully made.

With magnets, small power generation systems can be started.

After all, in the current era, to build a large-scale hydropower station, many technical problems need to be tackled.

For example, cement.

But even if there is cement, the hydropower station cannot be built, not to mention that the development of large-scale hydroelectric generators has not yet begun, and Zhu Jianji's Daming Royal Electric Power Company currently does not have the economic and technological strength to lay a power network across the country.

It needs to be taken one step at a time.

The first step, of course, is to pool money!

It's easy to get things done with money.

First, develop and produce small-scale power generation systems, and then sell them to the rich and powerful people in the country, so as to collect a large amount of funds to establish a small-scale power grid, and when the funds are enough to develop a hydropower system, then build a hydropower station, and then build a hydropower station, you can network the local small-scale power grid to form a regional power grid.

Just do it.

Zhu Jianji summoned Lu Chunjing to the Wenhua Hall early in the morning and asked, "How much money is still lying on the account of the Daming Royal Power Company?" ”

Lu Chunjing is like a few treasures, "Twenty-one thousand two hundred and thirty taels." ”

From its establishment to the present, the Royal Power Company has only built an office building, allowing Zhao Chuanjia and Zhu Bi to go to the Leizhou Peninsula twice, and the 300,000 taels that were allocated to the account at the beginning still have a surplus.

Zhu Jianji thought about it for a while, knowing that the accounts were not boring, and said with a smile: "Gu will allocate funds for you, and after the money arrives, you will first send someone to buy a large number of trees around Gyeonggi, pine or eucalyptus, and the main trunk is required to be straight, between two and three zhang long, and between half a foot and one foot thick." ”

Lu Chun nodded, "It's not difficult. ”

Zhu Jianji shook his head with a smile, "Where is this, after the trees are bought, they are burned with fire, they are scorched but not broken, they must master the heat, the surface happens to be the most perfect carbonization, and after that, all the trees are painted and air-dried for later use!" ”

Actually, it's a telephone pole.

Lu Chunjing was a little confused when he heard it, and hurriedly asked Dai Yi to find rice paper and pen and ink, and recorded all Zhu Jianji's words.

Zhu Jianji told Lu Chunjing that the Daming Royal Bank was ready to prepare for the construction of a series of departments such as a telephone pole factory, a light bulb factory, and a wire factory, so that after the experiment was successful, it would be able to be mass-produced immediately.

After Lu Chunjing left, Zhu Jianji began to prepare for the experiment.

The first step is to prepare tens of meters of copper wire.

It is not enough to have copper wire, but also need to get insulating materials, if there is no insulating material to wrap it, the effect and quality will be very poor, and there will be potential safety hazards.

There are two options that can be used for insulators.

ceramics and lacquer.

Lacquer has been available since ancient times, and the Ming Dynasty also has it, but it is expensive, but it can still be bought.

Ceramics can be customized.

Zhu Jianji has a two-pronged approach.

Lacquer is simple and purchased on the market.

Ceramics are more difficult.

Zhu Jianji asked Dai Yi to walk around Gyeonggi and invited the master of one of the most prestigious ceramic kilns to the East Palace—in fact, the real good master was in Jingdezhen.

However, Zhu Jianji is not a work of art.

So the average master is enough.

Zhu Jianji said the request, the master looked embarrassed, and said: "His Royal Highness the Prince, the grass people have never made this style of porcelain, the main reason is that the length is too long to pull the embryo, if our porcelain kiln wants to do it, we can only try to pull out the length within the range of the ability to do our best, and it will be impossible to grow any longer, so we need to try many times." ”

Zhu Jianji shook his head and said: "I don't have so much time for you to try, just do what Gu said, make a large number of finished products, and burn them out in one kiln, even if there is one out of ten, it is okay." ”

How dare the old master say anything.

Zhu Jianji smiled and said, "Don't worry, Gu will not let your porcelain kiln suffer, once you successfully burn the long porcelain pipe of Gu Yao, Gu will merge it into the industry of the East Palace at a high price." ”

The old master is overjoyed, the imperial businessman......

That's a good feeling!

Immediately said: "It is the duty of my people to be loyal to His Highness." ”

Zhu Jianji sighed, the old man was quite good at talking.

Said: "Lone has another requirement, these porcelain tubes must be glazed inside and out." ”

The master was puzzled, "The outer glaze is for good looks, and the inside is glazed for what?" ”

Zhu Jianji said nothing but didn't explain to him.

The glaze inside is to not hurt the copper wire, if the copper wire is injured, it will lead to safety accidents such as wire burning, so it is better to do it at one time.

The problem of wire and pipe is solved, and the wick is also solved.

This question......

Only Zhu Jianji can solve it himself.

Let Dai Yi buy all kinds of bamboo, find a carpenter master, cut the bamboo into a zigzag shape of earthworm thickness, like a winding mountain road, make a certain amount, and then take all of them to steam.

The wick is solved.

And then there's the light bulb.

Lu Chunjing has found the best glaze workshop near Gyeonggi, and according to Zhu Jianji's intentions, the acquisition of the glaze workshop is included in the Royal Power Company.

Zhu Jianji summoned the master of the glaze workshop, and after some inquiry, he went out of the palace in person and witnessed the master and his workers blowing out a bunch of glazed utensils in the shape that Zhu Jianji wanted.

Any strange shape of a glass container, you can blow it out!

The bulb problem is perfectly solved.

Poles, wires, bulbs, conduits, wicks......

All preparations are in order.

Make planks.

Make the rollers.

Making all kinds of washers - polishing with wood chips and polishing them into a washer style, fortunately, the carpentry master is highly skilled, and it is not difficult to make.

A U-shaped frame is then made out of wooden planks.

Measure the size accurately, make the plug of the bulb out of bamboo chips, ensure the tightness of the inside, and of course, paint it to ensure that it is truly impermeable.

Put the wick made of bamboo as the material into the bulb, connect the copper wire, leave half of each pole for easy testing, and then start to build the experimental equipment.

The U-shaped frame is in place, the center of the drum is first opened, then the copper wire is wrapped, the rotor made of wood is passed through the U-shaped frame, and then through a hole in the drum, and then the magnet is put in, the hole is passed, and the other section of the drum is passed and erected on the U-shaped frame.

Connect the left and right ends of the copper wire on the drum to the bulb.

A small electromagnetic induction generator is formed!

Everything is ready, just waiting for the magnet.
