The principle and structure of the DC generator were very simple. When Roland was a child, he had dismantled more than ten motors of four-wheel-drive vehicles, from ordinary white motors to the legendary Jinchao, and he had even wound the rotor copper wire by himself. These motors were typical DC motors.
These motors were typical DC motors.
There was no difference in structure between the DC generator and the DC motor. In essence, they were the same thing, and their functions could be interchangeable. As long as other machines drove the motor rotor to rotate, and the wires continuously cut the magnetic induction wire, it could generate a continuous flow of induced current.
With the help of Mystery Moon and Anna, Roland only spent half a day to assemble a simple DC motor. The stator was made entirely of wood, and Mystery Moon gave it magnetism. The commutator at the end of the rotor was embedded in a log, and the center of the log had a hole, which could be connected to the steam engine shaft. This structure was not only convenient to make, but also guaranteed the mutual insulation between the commutator.
As for the new steam engine, he and Mystery Moon watched Anna perform her amazing processing skills. When it was necessary to make large parts, she would spread out her black fire and wrap a pile of iron ingots like a cloth. After melting, she would shrink the black fire and press it into a plate that met the requirements, and finally cut it into shape.
The next day, when Roland was ready to go to the backyard of the calcining room to test the effect of the generator, the guard brought him a piece of good news, which made him very happy. The Chief Alchemist from the Redwater City Alchemy Workshop had arrived in Border Town, and he was accompanied by more than one person.
*****
Kyle Sichi was very decisive. In the afternoon, he took his family and more than ten disciples to board the merchant ship to Border Town. Unfortunately, after much hesitation, Chavez refused his invitation.
He did not disclose the contents of the letter to other alchemists, because the more people who knew, the later the departure time would be. Kyle was worried that the news of the success of the crystal glass would soon reach the ears of the Duke, and then it would not be so easy to leave — for such a high-profit luxury product, the Duke would definitely want to keep it in his hands.
He had written the formula and firing method of the crystal glass on a parchment, which was stored in the formula cabinet in the refining room, as a reward for the Duke's investment in building the alchemy workshop. But in front of the truth of alchemy, whether it was crystal glass or alchemy workshops, they weren't worth mentioning.
Five days later, Kyle finally met the person who had written the letter – the Lord of Border Town, Roland Wimbledon.
In the castle's reception hall, he had just bowed and had not even sat down when he impatiently said, "Your Highness, I want to have a good talk with your alchemist."
"My alchemist?" The other side smiled, "Before you came, there was no alchemist in Border Town. But now, you are my alchemist. "
"You mean … those alchemy formulas were written by you?" Kyle directly ignored the latter half of his sentence, his face turning pale. He suddenly thought of another possibility. The other party was a prince, and all the knowledge he received came from the palace tutors. If he knew all this, didn't it mean that the Alchemy Workshop of the King's City had already mastered the essence of alchemy? Yet, he was delusional enough to think that he was above them. This was simply too laughable.
"Not exactly," Roland said, "these formulas came from an ancient book more than 400 years ago, and I found them by accident. It seems that hundreds of years ago, they called alchemy chemistry. "
"Chemistry …?" When Kyle heard that the formulas didn't come from the Alchemy Workshop of the King's City, his heart suddenly felt a lot better, but the answer given by the prince still surprised him. Alchemy books from more than 400 years ago? One must know that the Alchemy Workshop of the King's City only had a history of less than 200 years. Could it be that the later generations were not as good as the predecessors?
"Yes, in the books, those scholars mentioned a hypothesis, which is the theory of the immortality of matter. The matter that makes up everything in the world will not disappear or increase, it just changes from one form to another, such as this pastry. "Roland pointed to the cake on the long table," After you eat it, part of it is absorbed by you, and part of it is excreted. If you add up the absorbed part and the excreted part, their mass should be equal. "
"Wait … Your Highness," Kyle thought for a moment, "If I burn a piece of wood into rice powder, no matter how I weigh it, the weight of the burned rice powder will be lighter than that of the wood. If the matter is immortal, then where does the missing part go? "
"This is also explained in the book," Roland said with a smile, "They become gas and water. The water is baked and evaporated by the flame, so in the end, you can only see the residue left. "
"Gas?" Kyle felt that something was about to come out of his heart, "Does the air also have weight?"
"Of course, all matter has mass." The prince nodded, "It's very simple to verify this point. Put a pile of sawdust into the bottle, cover the mouth of the bottle and place it on the balance scale. When the balance is reached, you will ignite the sawdust. Eventually, you will find that the weight of the bottle will not change. Because the gas released from the combustion can't escape, it remains in the bottle. "
"This … is also written in the ancient book?" Kyle asked eagerly, "Can you let me see that book?"
"If you can promise me a few conditions," Roland said, spreading out his hands.
"Please go ahead."
"First of all, you have to work for me, and your salary will be calculated according to your salary in the Redwater City Alchemy Workshop. Second, once you accept this job, you must abide by the confidentiality regulations. That is to say, you must not disclose the content of your work to other alchemists. Third, if you agree, we will sign a contract. This contract will last for five years. After five years, you will be free to choose whether to stay or leave, and your alchemy results will no longer be restricted by the confidentiality regulations. You can show them to other alchemists or the Alchemy Guild. In return, if you accept these three conditions, Border Town will provide you with housing and a chemical laboratory. At the same time, I will lend you the book 'Elementary Chemistry' to read. If there is anything you don't understand, you can ask me. "
"It doesn't sound like harsh conditions," Kyle thought. Although words like confidentiality regulations and chemical laboratory were difficult to pronounce, he could still understand the general meaning. A five-year contract was not too long. He had thought that the Lord would ask him to stay in Border Town forever.
And … even if the conditions were harsh, he wanted to see the book that recorded the essence of alchemy with his own eyes.
Thinking of this, Kyle got up and slightly bent down. "I am willing to serve you, Your Highness."
"Very well, then it's settled." The Prince didn't seem to care much about etiquette. "Your workplace will be by the Redwater River. After signing the contract, I will take you to familiarize yourself with the laboratory, and introduce you to the use and operating procedures of the glassware."
What made the chief alchemist feel a little strange was why His Highness talked about alchemy so skillfully, and even gave people a sense of confidence. Was he just an ordinary noble who had accidentally come into contact with an ancient alchemy book? But these were all minor details. He suppressed his doubts and asked, "What does Your Highness want me to refine?"
