In the small courtyard, Zhu Zhanqing ordered Chu'er to gather abalone, sea cucumber, fish lip, king oyster mushroom, tendons, flower mushrooms, cuttlefish, scallops, quail eggs, etc. together, add broth and old wine, and simmer over low heat.
Zhu Zhanzhen was following the recipe of Buddha Jumping Over the Wall, but he had only eaten this expensive thing once, so he knew that it was a one-pot stew, how to stew it, and how long to stew it. He didn't know, so he left it all to Sang Yu.
Sang Yu was cooking carefully in the courtyard. They were all made of expensive materials, and it would cost a lot of money to make a bad pot.
"Just keep doing it, don't worry about money, I have plenty." Zhu Zhanzhen was rewarded with two hundred taels of gold this time, and instantly became a nouveau riche.
Chu'er was a little anxious: "Your Highness, all the money has been spent. What will happen if it's gone?"
"Don't worry, the money will come back after you use it."
Xiaosheng walked in with a letter in his hand: "Your Highness, Miss Cao's letter."
Zhu Zhanzhen sat up from the recliner and took the letter. There was a girl's fragrance on it. He must have put some good-smelling powder on it.
He tore open the letter and read it to himself.
"His Royal Highness Wanan: The shuttle loom has been received. The female workers have given some suggestions for improvements after using it to Mr. Zhang San. The cotton needed in the north is within the plan and will not hold back His Highness. Mother has started to prepare for the supply and marketing
She, please rest assured, Your Highness."
The text was very short. After reading it, Zhu Zhanzhen felt depressed: "They are all serious things."
Chu'er reminded: "Your Highness, Miss Cao looks naughty, but she is actually shy and reserved."
Do you want her to reply that I missed you on the boat too?
It took her all night to write just these few words. She was afraid of not writing a word well, and she was afraid that she would write too much and rewrite it. She would use more paper in one night than a homebody.
Apparently she has matured a lot since her mother's incident, and has become much less frizzy.
Zhu Zhanchen picked up the pen, thought for a while and then wrote.
"Your letter is too official, and you don't even say you miss me."
Love letters should be copied as they should.
Another little eunuch came back, holding a magnet and some copper wire.
Seeing these things, Chu'er knew that His Highness had to tinker with some strange things again.
Zhu Zhanzhen had been free recently and thought that the steam engine was developing well, and Zhang San and other craftsmen were constantly learning and improving, so that he could tinker with other things.
Make electricity.
As an excellent car mechanic, he has encountered more than one car generator, and the principle of the generator is junior high school knowledge and is not very difficult.
Of course what we need to do now is not something as complex as a car generator, but simply make a device for cutting magnetic field lines and make a prototype of an electric light.
If there is electricity but no use, it is of no use.
Copper wire, magnets, carbonized bamboo wire, and wheels are also simple things.
Because he couldn't get tungsten wire, Zhu Zhanzhen used carbonized bamboo wire. In the beginning, light bulbs were made of this stuff. Even the durability and lifespan were not good. But now he has studied the principle clearly and then asked Zhang San
Just wait for others to perfect it.
I am responsible for thinking and you are responsible for doing.
Magnets include natural magnets and artificial magnets. my country has records of manufacturing magnets since the Song Dynasty.
The method of making guide fish is recorded in the Military Classics.
The guide fish is made of a thin piece of steel and is shaped like a fish.
Cut it with a thin iron leaf, two inches long and five minutes wide, with the head and tail as sharp as a fish. Place it on a charcoal fire and burn it. After it is red, use an iron sword to hold the fish head out of the fire. With the tail facing the fish head, dip it in a basin of water.
If there is no last digit, stop it and collect it with a secret weapon.
That is, placing the red-hot iron piece in the direction of the meridian and placing it in the water at a certain angle will increase the effective magnetic field strength for magnetizing the fish, and the magnetization effect will be better.
Of course, Zhu Zhanzhen used natural magnets.
Make a copper sheet into a collector ring, then wind the copper wire into a coil and connect it to the runner. The other end is close to the collector ring. There is a copper wire outside the collector ring connected to the carbonized bamboo wire to create a simple closed circuit.
.
When a part of a conductor in a closed circuit moves in a magnetic field to cut the magnetic induction line, the conductor will generate a current.
Zhu Zhanzhen started to spin. After spinning for a long time, he didn't see any sign of the carbonized bamboo silk lighting up.
Several people looked at Zhu Zhanzhen with confusion, and Zhu Zhanzhen himself also had a look of confusion on his face.
It shouldn’t be, the principle is correct.
I checked and improved the connection between the copper slip ring and the coil. Once the rotation starts, the connection between the two is easily disconnected. If the circuit is not closed, there is no way to generate current.
Zhu Zhanchen started turning again, this time speeding up.
As the coil continued to rotate rapidly, the carbonized bamboo silk gradually reacted and slowly lit up.
"Wow."
Chu'er and others exclaimed in surprise, and while they were exclaiming, the carbonized bamboo filaments glowed brightly, and then immediately broke and went out.
"Wow, I thought it was going to catch on fire just now." Chu Er was startled.
"Your Highness, what happened?"
"This is called electricity."
"Electricity? Lightning's electricity?"
"To put it simply, it can be understood like this."
Chu'er was confused: "But I didn't hear any thunder just now."
"This electricity doesn't require thunder, and we can make it ourselves."
"Really? Then Your Highness has turned into a Thunder God and a Lightning Girl."
"This is not magic, this is science."
"Science?" Xiaosheng and Chu'er both muttered the word to express their confusion.
Zhu Zhanzhen is in a very good mood. Now he has to find time to go out to find Zhang San and others. He only has theoretical foundation to support him, and the tools and the like are all there. Moreover, he has to say that he still loses to Zhang San in terms of practical ability.
Third-class craftsman.
Zhu Zhanzhen was confident that the generator could be made after a period of time, but the light bulb was not that simple. The carbonized bamboo filament could only be sustained for a while before burning out, and it could not last long in the air.
If it can be evacuated or kept in a pure nitrogen environment, it can last for a longer time, but in the end you still have to find tungsten wire.
Don't even think about tungsten wire at this stage. Zhu Zhanyi does not have the professional knowledge to support him in refining tungsten wire. He can only try to see if the newly built smelting plant can do this. It is quite difficult at this stage.
Zhu Zhanyi ran out of the palace excitedly. He was about to leave the palace, but he was stopped. The prince had an order and Zhu Zhanyi was not allowed to leave the palace unless it was a special situation. It was too convenient for Zhu Zhanyi to leave the palace before.
That's why it happened that he could sneak out. Now like other princes, he has to get Zhu Gaochi's permission before he can leave the palace.
Zhu Zhanyi simply walked to the Prince's East Palace and walked straight in.
"Father, I have made another major discovery. As long as it is successfully applied, it will definitely change the world."
Zhu Gaochi smiled bitterly and said, "What discovery?"
