Magus Tech

　　 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 spreading a long scroll on it, using the quill to quickly draw something.

　　Edouard looked suspicious and stood beside him not to be bothered. The craftsman didn't even have this courage. He kept his head down honestly and didn't say a word. He just glanced at the scroll painted by Li Cha from time to time. He felt that His Royal Highness the Prince was painting a machine. It looks like a windmill, but it's more complicated...

　　 "Shusha..."

　　 After a long time, Licha put down his quill pen, glanced at 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 in his fifties, but he is actually only in his forties. The life of craftsmen in the current world is not easy. Even if employed by the palace, it is only better than some serfs. The long hours of fatigue make the other party very old.

　　'S face was covered with wrinkles, two eyes were deeply concave, and a heavy eye bag was dragged underneath. At this time, he was looking at with anxious eyes.

　　 "You call Mark right?" Richard said.

　　 "Hum, goo... back to His Royal Highness, I... the younger is Mark." The craftsman quickly said, His Royal Highness could accurately call his name, with a little surprise and fear in his voice... After all, a small person, remembered by His Royal Highness, is not necessarily a good thing.

　　 Richard waved directly: "Come and see this design picture I drew, can you understand it."

"Yeah, yes." The craftsman quickly approached, his gaze fell on the scroll, carefully glanced at it, 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 to build it? Give you up to five days." Richard said.

　　 "Ah, this..." The craftsman hesitated, looked at the design drawings, estimated the workload, and said uncertainly, "It should be fine."

　　 "Let's take a closer look and make sure to say it again. If you don't understand something, you can ask me now and I will solve it for you. Don't tell me when there is a problem and you can't finish it." Richard said.

"Yeah, yes." The artisan said with a sweat on his face that he couldn't help but looked at the design again. His eyes flickered, and he suddenly realized that the design was really not what he had just thought. Simple, at least compared to ordinary windmills, there are many parts that he can't understand.

　　 quickly reached out and pointed out: "His Royal Highness, this... this place... there seems to be some problems, the general windmills are not all installed on a pillar, how is the place where this windmill is installed..."

　　 Richard glanced and said slowly: "This is the turret."

　　 "Turret?" The craftsman froze.

"General windmills can indeed be installed on the pillars. The structure is simple and easy to manufacture. However, the disadvantage is that they cannot always adapt to the wind direction. They need to be manually adjusted, which is laborious and inefficient. But according to this design, 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, and you can make the most of the wind at all times." Li Cha explained.

　　Craftsman's eyes widened and was startled: "Really... can it really be like this? But... but His Royal Highness, how did this happen, the wind... will not come from one direction, it may be any direction..."

"Because there is this part on the turret." Richard pointed a little 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 is from Blowing in the direction, as long as the tail fan is blown, 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."

　　 listened to the craftsman, scratching his head still didn't quite understand it, but at least one thing was clear from Richard's words: His Royal Highness the Prince did not just talk nonsense, but really understood it, and knew much more than him.

In this case……

　　 Next moment, the craftsman took a deep breath and found the next place where he did not understand and asked: "His prince, here..."

"Ah, these two heavy **** swinging outward on the cantilever are centrifugal governors. You don’t need to know the principle. Just understand that they can be used to automatically adjust the rotor speed to adapt to different wind speeds. That’s all. It’s the technology in the windmills of the 19th century. It’s a bit early, but it should be able to be made.”

　　 "Ah, okay... Then His Royal Highness, this rotor..."

"This." Li Cha took the quill and waved off the corresponding part. "This part is a bit complicated. I don't need you. I'll do it myself. It's what I use to sense electricity, and it needs manual labor. You can’t make a magnet."

　　 "Well, then this part of His Royal Highness is..."

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

　　 "His prince is here..."

　　 "This is the part that stores the electric current, I come in person, you only reserve the corresponding part..."

　　 "So here..."

　　 "......"

It took more than an hour for the craftsman and Richard to fully understand all the details on the design drawing, wiped the sweat on his face, and said: "His Royal Highness, this windmill seems really a bit difficult, only Fear of five days..."

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

　　 "Ah, this..." The craftsman narrowed his neck and didn't dare to refuse. UU read the book www.uukananshu.com and gritted his teeth and nodded, "Well, sir, my prince, I will make it in a week."

"that's OK."

The craftsman took the design and left. Edward was about to say something next time. Richard had already looked at him first and said, "Edward, you can help me find some iron filings and some rust powder." ."

　　 "Ah?" Edward froze and asked what he had always wanted to say, "His Royal Highness, what the **** do you want to do?"

　　 "You will know by then." Richard said.

　　 "Well, okay." This answer is almost the same as no answer. Edward shrugged and turned away helplessly.

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

　　……

　　 In the afternoon, an independent laboratory.

　　The afternoon sun shone in and it was extremely bright.

　　Richard looked at the dozens of pounds of iron filings and rust powder on the experimental table and nodded satisfactorily. Although Edward's swordsmanship was mediocre, he still had the ability to handle things.

　　According to Edward, these iron filings and rust powder together weigh more than 100 pounds. Pounds are British and American units of mass. 1 pound is 0.45359237 kilograms, which is 0.9071847 kilograms. However, according to the habit, every time someone hears this British-American unit, Richard is automatically converted into a memory unit in the brain.

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

　　 The reason why there are so many iron filings and iron filings is that there is no other reason, that is-to make the rotor and use it on the windmill.

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