Magus Tech Chapter 19: Craftsman

Soon, the artisans of the kingdom arrived at the restaurant where Richard was.

The food on the dining table has been taken away, and Li Cha is spreading out a long scroll on it, quickly drawing something with a quill.

Edward stood by the side with a puzzled look on his face, not daring to disturb him. The craftsman didn't even have the guts to do so. He lowered his head obediently and didn't say a word. He just secretly glanced at the scroll drawn by Li Cha from time to time, thinking that His Royal Highness seemed to be drawing a machine. It looks like a windmill, but it's more complicated...

"Shushasha..."

After a long time, Li Cha put down the quill in his hand, glanced at the contents on the scroll, nodded slightly, and then turned his head to look at the craftsman who had been waiting for a long time.

The craftsman is a man who looks to be in his fifties, but in fact he is only in his forties. At present, the life of artisans in this world is not easy. Even if they are hired by the palace, they are only better than some serfs. The long-term fatigue makes them look old.

His face was covered with wrinkles, his eyes were deeply sunken, with heavy bags under his eyes, and he was looking at him with anxious eyes.

"Your name is Mark, right?" Richard said.

"Um, Gudong... If you want to return to His Royal Highness, I... the younger one is Mark." The craftsman hurriedly said, but he didn't expect His Royal Highness to call out his name accurately, with a bit of surprise and... panic. After all, it is not necessarily a good thing for a small person to be remembered by His Royal Highness.

Li Cha waved his hand and said directly: "Come here and take a look at the design I drew, can you understand it?"

"Uh, yes." The craftsman hurriedly approached, his eyes fell on the scroll, he glanced carefully, confirmed his guess just now, and asked tentatively, "This... this seems to be... a scroll. Windmill, Your Highness?"

"Yes, it is indeed a windmill, so are you sure you can make it? I will give you five days at most." Richard said.

"Ah, this..." The craftsman hesitated for a moment, looked at the design drawing, estimated the workload, and said uncertainly, "It should be possible."

"Take a closer look and tell me when you are sure. If there is anything you don't understand, you can ask me now, and I will solve it for you. Don't tell me that there is a problem and the project cannot be completed." Richard said .

"Ah, yes yes." The craftsman said on his face, he couldn't help sweating his face, he looked at the design drawing again, his eyes flickered, and suddenly found that the design drawing really didn't seem to be what he just said It's so simple, at least compared to ordinary windmills, there are many parts that he can't understand.

Hastily stretched out his hand and pointed: "Your Highness, this... this place... seems to have some problems, ordinary windmills are not all installed on a pillar, why is the place where this windmill is installed..."

Li Cha took a look and said slowly, "This is the turret."

"Turret?" The craftsman was stunned.

"Ordinary windmills can indeed be installed on pillars. They have a simple structure and are easy to manufacture. But the disadvantage is that they cannot always adapt to the wind direction and need to be manually adjusted, which is laborious and inefficient. However, according to this design drawing, the windmill The blades are installed on a special turret, and the turret can automatically rotate around the central axis to face the wind direction, so that the wind can be used to the greatest extent at all times." Li Cha explained aloud.

The craftsman's eyes widened and he was startled: "Really... can this be done? But... But Your Highness, how did you do it? The wind... doesn't come from one direction, it could be from any direction ..."

"Because there is this part on the turret." Li Cha pointed his finger on the design drawing, "Behind the main blade, there is a tail fan at right angles to it, which is connected to the gear track on the edge of the turret. So no matter When the wind blows from that direction, as long as it blows through this tail fan, the tail fan will push the turret to rotate, ensuring that the main blades of the wind tower are always aligned with the wind direction.”

After hearing this, the craftsman scratched his head and still didn't quite understand, but he understood at least one thing from Li Cha's words: His Royal Highness is not just talking nonsense, but really understands, and knows more than him.

In this case...

The next moment, the craftsman took a deep breath, found the next thing he didn't understand and asked: "Then, Your Highness, here..."

"Well, these two heavy **** swinging outward on the cantilever are centrifugal governors. You don't need to know the principle, as long as you understand that it can be used to automatically adjust the speed of the rotor to adapt to the speed of the rotor. Different wind speeds are fine. This is the technology of windmills in the 19th century, and it is a bit early now, but it should be completely possible to make."

"Um, well...then His Royal Highness, this rotor..."

"This." Li Cha picked up the quill and swiped the corresponding part, "This part is a bit complicated, so I don't need you, I'll do it myself. It's for me to induce electricity. You can’t make it with artificial magnets.”

"Okay, then the part of His Royal Highness is..."

"This is an improved crankshaft, which is used to transfer energy to drive the rotor. Please pay attention here..."

"Then His Royal Highness is here..."

"This is the part that stores the current. I will come in person. You only need to reserve the corresponding part..."

"Then here..."

“…”

……

The craftsman and Li Cha talked for more than an hour before finally figuring out all the details on the design drawing, wiped the sweat off his face, and said: "Your Highness, this windmill seems to be really difficult. Ah, I'm afraid it will take five days..."

"That's a week." Richard said, his voice a little serious, "but it can't be longer, my time is limited, and I can't delay it."

"Ah, this..." The craftsman shrank his neck and dared not refuse ~IndoMTL.com~ gritted his teeth and nodded, "Alright then, Your Royal Highness, I will definitely make it in a week."

"Well, that's good."

The craftsman took the blueprint and left. The next moment Edward was about to say something, Li Cha had already looked at him first, and ordered: "Edward, help me find some iron filings, and some Rust powder comes."

"Ah?" Edward was taken aback, and asked what he had been wanting to say just now, "Your Highness, what exactly are you trying to do?"

"You will know when the time comes." Richard said.

"Uh, okay." This answer was almost the same as no answer, Edward shrugged, turned around and left helplessly.

By the afternoon, the iron filings and rust powder were sent to Richard's independent laboratory.

……

Afternoon, Independent Lab.

The afternoon sun shone in, extremely bright.

Li Cha looked at the dozens of kilograms of iron filings and rust powder on the experimental table and nodded in satisfaction. Although Edward's swordsmanship is mediocre, he still has the ability to handle affairs.

According to Edward, the combined weight of these iron filings and rust powder exceeds 100 pounds. Pound is a British and American unit of mass, 1 pound is 0.45359237 kilograms, which is 0.9071847 catties. However, according to his habit, every time he heard someone mention this British and American unit, Li Cha would automatically convert it into the unit of memory in his brain.

1 pound is about 0.9 catties, and more than 100 pounds is more than 90 catties, which is indeed a lot.

And there is no other reason why so many iron filings and iron filing powders are needed, that is-to make rotors and use them on windmills.

This is the most fundamental method that Li Cha decided to use, and it will never fail, the method of making electricity.
