Chapter 19 The Craftsman

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

The food on the table has been taken away, and Richard is rolling out a long scroll on it, drawing something quickly with a quill.

Edward looked puzzled and stood beside him, not daring to disturb. The craftsman didn't have the courage, he kept his head down, didn't say a word, just glanced at the scroll that Li Cha was drawing from time to time, and felt that His Royal Highness seemed to be drawing a machine. It looks like a windmill, but it's more complicated...

"Swish..."

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 to look at the craftsman who had been waiting for a long time beside him.

The craftsman was a man who looked in his fifties, but he was actually in his forties. At present, the life of craftsmen 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 the other party very old.

His face was wrinkled, his eyes were sunken, and heavy bags were dragged under his eyes, and he was looking at him with uneasy eyes.

"Your name is Mark, right?" Li Cha said.

"Uh, gu dong... When I go back to His Royal Highness, I... The youngest is Mark." The craftsman said quickly, but he did not expect His Highness to call out his name accurately, with a bit of surprise and... panic in his voice. After all, a small person, remembered by His Royal Highness, is not necessarily a good thing.

Li Cha waved his hand and said directly, "Come here and see if I can understand this design drawing I drew."

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

"Yes, it is indeed a windmill, so are you sure you can make it? I'll give you five days at most." Li Cha said.

"Uh, this..." The craftsman hesitated for a while, looked at the design drawings, estimated the workload, and said uncertainly, "It should be possible."

"Take a closer look, and then say it again. If there is anything you don't understand, you can ask me now, and I will solve it for you. Don't tell me when there is a problem, and it cannot be completed." Li Cha said.

"Uh, yes yes yes." The craftsman said on his face, sweat dripping from his face, looked at the design again, his eyes flickered, and suddenly found that the design really didn't seem to be what he thought. Simple, at least compared to ordinary windmills, there are many parts that he can't understand.

He quickly stretched out his hand and pointed: "His Royal Highness, this... this place... there seems to be some problems. The ordinary windmills are not all installed on a pillar. Why is this windmill installed like this..."

Li Cha glanced at it and said slowly, "This is the turret."

"The turret?" The craftsman was stunned.

"General windmills can indeed be installed on the pillars, with simple structure and convenient production. But the disadvantage is that they cannot always adapt to the wind direction, and need to be adjusted manually, which is laborious and inefficient. According to this design drawing, the windmill blades are installed on the On a special turret, 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 every moment." Li Cha explained aloud.

The craftsman's eyes widened and he was shocked: "Really... Really? But... But His Royal Highness, how did this happen, the wind... It doesn't come from one direction, it could be from any direction..."

"Because there is this part on the turret." Richard pointed a finger on the design drawing. "Behind the main blade, there is a tail fan at a right angle to it, which is connected to the gear track on the edge of the turret. So no matter where the wind comes from 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 listening to 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 he really understands, and knows more than he does.

In this case……

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

"Well, these two heavy balls swinging out on the cantilever are centrifugal governors. You don't need to know the principle, just understand that it can be used to automatically adjust the rotor speed to adapt to different wind speeds. That's it. It's 19th-century windmill technology, and it's a bit early, but it should be fully achievable."

"Uh, okay... The prince, this rotor..."

"This." Li Cha picked up the quill and swiped the corresponding part, "This part is a bit complicated, I don't need you, I'll do it myself. Magnets, you can't make them yet."

"Okay, that part of His Royal Highness is..."

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

"Then His Royal Highness is here..."

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

"Then here..."

"..."

...

The craftsman and Li Cha talked for more than an hour before finally figuring out all the details on the design drawings, wiping the sweat off his face, and said, "His Royal Highness, this windmill seems to be really difficult, only Afraid of five days..."

"Then it'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."

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

"Ah That's good."

The craftsman left with the blueprint. The next moment Edward was about to say something, but Richard had already looked at him and said, "Edward, go and find some iron filings and some rust powder for me. ."

"Ah?" Edward was stunned for a moment, and asked what he had always wanted to say, "His Royal Highness, what are you trying to do?"

"You'll know when the time comes." Li Cha said.

"Uh, okay." This answer was similar to no answer, Edward shrugged, turned helplessly and left.

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

...

In the afternoon, independent laboratory.

The afternoon sun shines brightly in.

Li Cha looked at the dozens of pounds of iron filings and rust powder on the experimental table and nodded with satisfaction. Although Edward's swordsmanship was mediocre, he still had the ability to handle affairs.

According to Edward, the iron filings and rust dust together weighed more than 100 pounds. The pound is the unit of mass in the British and American systems, 1 pound equals 0.45359237 kilograms, which is 0.9071847 kilograms. However, according to habit, every time he heard someone mention this Anglo-American unit, Richard would automatically convert it into a memory unit in his brain.

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

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

This is the most fundamental method that Richard decided to use, and it will never fail, to make electricity.
