Soon, the kingdom's craftsmen arrived at the restaurant where Richard was.
The food on the table has been taken away, and Richard is spreading a long scroll on it and drawing something quickly with a quill.
Edward looked confused and stood nearby, not daring to disturb. The craftsman didn't have the guts to do so. He kept his head down and didn't say a word. He only glanced at the scroll painted by Richard from time to time, feeling that His Highness seemed to be drawing a machine. Looks like a windmill, but more complicated...
"Shashasha..."
After a long time, Richard 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.
The craftsman is a man who looks to be in his fifties, but is actually only in his forties. The current life of craftsmen in this world is not easy. Even if they are employed by the palace, they are only better than some serfs. The long hours of hard work make them look old.
His face was covered with wrinkles, his eyes were deeply sunken, and there were heavy bags under his eyes. He was looking at him with anxious eyes.
"Your name is Mark, right?" Richard said.
"Uh, Gudong... To answer His Highness, I... the youngest is Mark." The craftsman said quickly, not expecting His Highness to call his name accurately, with a bit of surprise and... panic in his voice. After all, it is not necessarily a good thing for a little person to be remembered by His Highness the Prince.
Richard waved his hand and said directly: "Come here and see if you can understand the design I drew."
"Um, yes." The craftsman quickly approached, his eyes fell on the scroll, and after scanning it carefully for a few times, he confirmed his guess and asked tentatively, "This... this seems... to be a windmill, Your Highness?" "
"Yes, it is indeed a windmill. Are you sure you can make it? I'll give you five days at most." Richard said.
"Um, um..." The craftsman hesitated for a moment, looked at the design drawing, estimated the workload, and said uncertainly, "It should be okay."
"Look at it carefully and make sure it is accurate. 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 it can't be completed until then," said Richard.
"Uh, yes, yes." The craftsman said on his face. He couldn't help sweating on his face. He looked at the design drawing again, his eyes flashed, and he suddenly realized that the design drawing was really not what he thought just now. Simple, at least compared to ordinary windmills, it had many parts that he couldn't understand.
He quickly pointed out his hand and said: "Your Highness, this... this place... seems to have some problems. Not all windmills are installed on a pillar. Why is this windmill installed like this..."
Richard took a look and said slowly: "This is the turret."
"Turntable?" The craftsman was stunned.
"General windmills can indeed be installed on pillars. They have simple structures and are easy to make. But the disadvantage is that they cannot always adapt to the wind direction and require manual adjustment, which is laborious and inefficient. To make it according to this design drawing, install the windmill blades on On a special turret, the turret can automatically rotate around the central axis to face the wind direction, so that the wind power can be maximized at all times." Richard explained aloud.
The craftsman's eyes widened and he was shocked: "Really...can this really happen? But...but Your Highness, how is this done? The wind...doesn't come from one direction, it could come from any direction..."
"Because there is this part on the turret." Richard pointed 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 where the wind comes from, If the wind blows in any direction, as long as it blows past 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 Richard's words: His Highness the Prince was not just talking nonsense, but he really understood it, and he knew much better than him.
In this case…
The next moment, the craftsman took a deep breath and found the next thing he didn't understand and asked: "Your Highness, here..."
"Well, these two heavy balls swinging outward on the cantilever are centrifugal speed regulators. 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 different wind speeds That’s it. This is the technology of windmills in the 19th century. It’s a bit early now, but it should be completely feasible.”
"Uh, okay... Then Your Highness, this rotor..."
"This." Richard picked up the quill and swung it, ticking out the corresponding part. "This part is a bit complicated. You don't need to be there. I can do it myself. I use it to induce electricity, and I need to use artificial intelligence." You can’t make a magnet yet.”
"Okay, then this part of Your Highness is..."
"This is an improved crankshaft, used to transfer energy to drive the rotor. Pay attention to this..."
"Then your Royal Highness, here..."
"This is the part that stores current. I'll do it myself. You only need to reserve the corresponding parts..."
"Then here..."
“…”
…
The craftsman talked with Richard for more than an hour before he finally figured out all the details on the design. He wiped the sweat from his face and said, "Your Highness, this windmill seems to be really difficult. I just want I’m afraid it will take five days…”
"Then it will take a week." Richard said, his voice a little serious, "But it can't be longer. My time is limited and I can't delay."
"Well, this..." The craftsman shrank his neck and did not dare to refuse. He gritted his teeth and nodded, "Okay, Your Highness, I will make it in a week."
"Ah That's good."
The craftsman left with the design drawing. The next moment Edward was about to say something, Richard had already looked at him first and said: "Edward, go and find me some iron filings and some rust powder." .”
"Ah?" Edward was stunned and asked what he had been wanting to say. "Your Highness, what on earth do you want to do?"
"You will know when the time comes." Richard said.
"Uh, okay." This answer was almost like no answer. Edward shrugged, turned around and left helplessly.
By the afternoon, the iron filings and rust powder were delivered to Richard's independent laboratory.
…
Afternoon, independent laboratory.
The afternoon sun shines in, extremely bright.
Richard looked at the dozens of kilograms of iron filings and rust powder on the experimental table and nodded with satisfaction. Although Edward's swordsmanship was mediocre, he was still capable of doing things.
According to Edward, the combined weight of these iron filings and rust powder exceeds 100 pounds. The pound is a British and American unit of mass. 1 pound equals 0.45359237 kilograms, which is 0.9071847 kilograms. However, according to his habit, every time he heard someone mention this British and American unit, Richard would automatically convert it into the remembered unit in his brain.
1 pound is about 0.9 kilograms. More than 100 pounds equals more than 90 kilograms, which is indeed a lot.
The reason why so much iron filings and iron filings powder is needed is for one reason - to make rotors for use in windmills.
This is the most fundamental and unfailing method of making electric current that Richard decided to use.
