Elf: I am a tutor

Although Ying Shanli has a Bi Diao that can carry people, it will take at least three or four hours to go back and forth between Kapu Island and the mainland, not to mention buying some things. .biqugev

Su Fang finally calmed down this "top" researcher and realized that he was really a genius. He had been involved in the research of the Supreme Alliance since he was nine years old. He didn't know how to continue to understand, so he could only imitate HR and asked: " Tell me about your project experience or any tangible results you have achieved.”

"You don't know what I have accomplished, why did you invite me here?"

"Well..." Su Fang smiled awkwardly, "Isn't this a chance for you to express yourself?"

Underneath Higashino Xiaoyun's white coat was a pair of dark blue overalls. He didn't know how he managed to wear so many clothes on such a hot day. He took out a low-quality rainbow-colored stick from the pocket of his overalls. The lollipop was in his mouth: "As for the things I participated in the research, the Supreme Alliance won't let you talk about it, otherwise it will scare you to death!"

Su Fang:......

"So you know why I invited you here?"

Dongye Xiaoyun tilted his head and stared at Su Fang. Could this be a stupid island owner? "You invited me here. How would I know if you didn't tell me?"

Suddenly his eyes became very alert: "Let me tell you first, although half a million a month is indeed tempting, I am definitely not that kind of person! Except..."

Just when Su Fang was about to explode, Damu Shenxu came back from washing up.

"Yeah, yeah, island master, where did you find this little lolita? I like lolita the most..."

Dongye Xiaoyun grabbed the hand that was trying to touch the top of his head with both hands, lifted his left shoulder high, moved to lean back, and threw him over his shoulder!

Omu Shenxu recognized the identity of the little loli in mid-air, covered his butt and shouted: "Dongye...ahhh! It hurts! Doctor?"

Seeing this, Su Fang could only add in his heart: Although I sympathize with you, I also like you, especially the rich ones.

"you know me?"

Da Mu Shenxu hurriedly hid behind Su Fang and whispered: "Don't look at her cuteness, maybe take it out... maybe one punch will kill you."

Dongye Xiaoyun hooked his index finger: "Come here."

"Do not."

"Can't come over?"

Su Fang could only intervene to stop him. He pressed his hand and said gently: "We will be working together from now on. Don't be so tit-for-tat. Let me tell you my thoughts first."

"Yes, boss, okay, boss."

Damu Shenxu asked in a low voice: "How much did it cost?"

"Fifty thousand a month."

"Five...five hundred thousand?!" Damu Shenxu stretched out his right hand, "Ten, twenty..."

Although Higashino Xiaoyun is also a Ph.D., he is not a Ph.D. in elf science. He has no independent research topics. He basically overcomes the problems given by the Supreme Alliance. Therefore, there is basically no funding and only a meager salary. Therefore, this game world , basically everyone goes for the Doctor of Elfology.

Although the salary is quite high compared to ordinary people, at least one hundred thousand level, it is still much less than the five hundred thousand offered by Su Fang.

"You have also seen that there is no infrastructure on this island. The power generation depends on the elves. The elves are not slaves. They cannot work for us for free. And when the island develops, we will know how many elves will be needed to provide power."

Dongye Xiaoyun jumped up and sat down on Su Fang's desk without a care, licking the lollipop diligently with his little tongue: "So just give them wages, power plants are like this now, electric elves For the sake of the Lord, give them some cheap elf food or something every day, since the elves are easy to get rid of anyway."

"No, I want to generate electricity naturally, without human power or elves."

“It’s possible to use either one, but it’s impossible to use both.”

Da Mu Shenxu kept nodding in agreement. He didn't know who was tied up yesterday, but he seemed to be very familiar with it today: "I feel the same way."

Su Fang didn't know how to tell Dongye Xiaoyun that there was such a thing as wind power. Su Fang also worked hard on the power plant. After thinking about it, only wind energy was the most reliable. At most, it would only limit the development of the power supply area.

"I thought so……"

Damu Shenxu nodded: "Well, you tell me, I'm listening."

"Can you get out of here first? Go and see who is waiting for you to go to class, and then we can do our business in the afternoon."

It wasn't until Da Mu Shenxu left that the room became quieter. Su Fang organized his words a little and said, "That's what I think. Thermal power generation is not about converting thermal energy into mechanical energy. In fact, it's just about finding ways to make the thing that drives the generator rotate." Just get up."

"Have you ever seen a windmill?"

"Click!" Biting the lollipop in one bite, Higashino Xiaoyun's eyes flashed with a hint of distress before he fell into deep thought.

Seeing this, Su Fang stopped talking. After a long time, Dongye Xiaoyun said: "It's possible, but how to calculate the energy of wind? In what form should it be converted? What if there is no wind? Subsequent power conversion is not a problem. ... I definitely don’t have enough for this thing alone.”

"Isn't it still me?" Su Fang picked up a piece of white paper and started to show off the knowledge of another world for the first time, "You see, the wind blowing on a certain area of ​​fan blades will cause the fan blades to rotate. Can we Think about it this way..."

"This is the density of air, roughly..."

Watching Su Fang scribbling on the paper, the curiosity in the little Loli's eyes became more and more serious: "I understand this, just tell me."

"Then this is the wind speed, this is the collision area, and this is the pi ratio. As long as the fan blade rotates, it will be approximately equal to the force on the entire circle. This is a constant, so the mechanical power can be calculated in this way. The only problem is this constant .”

"Everything else is basically constant, so this constant determines the mechanical power that will be produced under these conditions."

Su Fang glanced at Dongye Xiaoyun. He only knew a little bit about it. He had learned about it before when he encountered a question that required calculation of Ye Jian ratio.

Dongye Xiaoyun's big eyes rolled up, and he had inadvertently stuffed two lollipops into his mouth: "Leave me alone, you continue."

"We can guess that this constant will not be infinitely large or infinitely small. If it is not fixed, it is likely to be a ratio. Then there are only a few factors that can affect the power. What is not mentioned in the previous formula is the rotation speed. I have calculated it before. , it’s probably this formula.”

Su Fang found that after explaining the meaning of this formula, he had nothing to say, because he only needed to do the questions to understand this. He felt a little guilty and said: "Well, that's about it, do you understand? "

"Nonsense, is there a time when a genius girl still doesn't understand?" Although Higashino Xiaoyun said this, she still rolled her eyes. This was probably a sign that she was thinking, but it was a little scary. "Give me some time to think."

It’s best if you understand, but I don’t understand anyway.
