Zhou Yan said that he couldn't ignore it, and entered the private room to wait for Jiang Ju.

Within a few minutes, Jiang Ju brought a middle-aged man with gray hair and about fifty years old to Goubuli Restaurant.

"This is Professor Shangguan, the No. 1 expert in the application of new energy in Huaxia." Jiang Ju introduced: "This is mine...... Good friend and also my student, Zhou Yan. ”

"Fortunately, fortunately." Professor Shangguan looked a little thin, wearing a pair of thick black-rimmed glasses, and he was very bookish.

"Nice to meet you." Zhou Yan smiled: "My name is Zhou Yan, a first-year student in the Department of Chinese. ”

"Freshmen?" Professor Shangguan was a little surprised: "Aren't you supposed to be training now?" ”

"I passed all the tests on the first day of military training, so I went back to school early." Zhou Yan said lightly: "Professor Shangguan, let's order food first, there are still a lot of questions to ask you in a while." ”

"Of course, I'll leave the ordering of these things." Jiang Ju unceremoniously took the menu and began to order.

"Professor Shangguan, what I want to ask is some basic knowledge of new energy applications, and I hope to give me advice." Zhou Yan said with a smile: "While the dishes are not ready yet, let's talk about it first?" ”

"New energy, according to the current international definition, refers to all energy sources except for underground resources." Professor Shangguan nodded, he could see Zhou Yan's eagerness to seek knowledge, and said with a smile: "For example, solar energy, such as nuclear energy, such as gravitational energy, such as tidal energy...... What do you want to know? ”

"All new energy, I want to know a little bit." Zhou Yan said: "Don't seek too deep understanding, just seek rough introductory knowledge." ”

"Even so. If you want to know all the basics of new energy. I'm afraid it will take about a month. Professor Shangguan said: "Then it has to be done when I don't have classes and don't work in an outside company." ”

"That's fine." Zhou Yan said: "Now I'm fine." As long as the professor is available, I will teach whenever I want. ”

"Speaking of new energy, I would like to ask, how do you understand the word energy?"

Professor Shangguan asked with a smile, "This should be the first step to understanding new energy." ”

"This ......" Zhou Yan thought for a while and replied, "Energy should be a natural resource from which various forms of energy such as heat, mechanical, electrical, chemical, light or nuclear energy can be obtained. There are two categories: primary energy and secondary energy. It is an indispensable source of fuel and power for the development of industry, agriculture, national defense, science and technology, and the improvement of people's lives, and an important material foundation for human survival. ”

"That's right, that's the written definition of energy." Professor Ouyang smiled: "Then what do you think?" Among these energy sources, what can be used for human beings, or for the earth? …… Take what you think is the most important. ”

"Hmm......" Zhou Yan thought for a while: "I think that the current technology can be preliminarily used, there should be nuclear energy, solar energy, tidal energy, gravitational energy, these major projects, right?" ”

"Yes." Professor Shangguan said: "At present, the most important civilian energy source that we humans can use is solar energy. ”

"Solar energy is currently the only energy source that can be used in large quantities in human life." Professor Shangguan said: "Actually, although I am a professor of new energy use. But I said that the only thing I know the most about is the civilian part of solar energy. ”

"Then let's talk about the knowledge of solar power civil use!" Zhou Yan smiled and said, "You can give a lecture." Don't worry I don't understand. ”

"That's good." Professor Shangguan said: "The sun, relative to the earth, is an energy source that does not cost anything at all, and its service life is close to infinite. ”

He continued: "The earliest use of solar energy can probably be traced back to the Zhou Dynasty in China, when there were records of Fu Sui borrowing fire from the sun......

As soon as he talked about his major, Professor Shangguan immediately began to talk about the earliest use of solar energy in China to the first solar power station used in Meiguo.

At first, Zhou Yan could still understand it, but when it came to some professional words in the back, he was at a loss for the second monk.

"Brother Almighty Scene Converter, come out quickly."

Zhou Yan said silently.

"Here we are." The universal scene changer came and said, "What scene is it converted to?" ”

"Transformed into a primary school nature teaching scene." Zhou Yan had already thought of the corresponding scenario and reached it.

"No problem." The universal scene converter said: "In the scene transformation, three, two, one!" ”

Zhou Yan's environment has changed.

Professor Shangguan seems to have become Zhou Yan's nature teacher in elementary school, holding a nature textbook, and is talking to Zhou Yan: "The sun, which appears on the horizon in the morning, shines on the whole earth with its own heat, giving the earth's creatures heat and the light energy needed for growth......

Of course, Zhou Yan understood this kind of knowledge as soon as he heard it.

Although Zhou Yan had known these things for a long time, under Professor Shangguan's explanation, Zhou Yan's mind gradually became clear about the use of solar energy.

"Got it?" Professor Shangguan spoke for a while, and found that Zhou Yan not only listened very carefully, but also kept nodding his head and asked, "Perhaps, I spoke a little too deeply......

"Just right." Zhou Yan said with a smile: "Professor Shangguan is really the professor who uses the most new energy, what you said is so good." Let me, a student who does not understand the use of new energy at all, suddenly open the house and benefit a lot! ”

"Then you sue me." Professor Shangguan looked at Zhou Yan strangely, he had been a professor for many years, but he had never met a student who could comprehend the basic knowledge of new energy use in such a short period of time: "What are the ways to use new energy?" ”

This question sounded in Zhou Yan's ears, but it became: "What is the main source of heat and light energy for living beings on the earth?" ”

Zhou Yan said with a smile: "Of course it's the sun, the sun appears on the horizon every morning, using its own heat and light energy to shine on the entire earth, giving all living beings the necessary light energy and heat." ”

This answer, which stopped in the ears of Professor Shangguan and Jiang Ju, was: "The main way to use new energy is to convert them into heat, potential, nuclear, electrical and other energy that we all use on a daily basis through a series of conversion processes. So as to drive machinery or related equipment to achieve the purpose of utilization. ”

"Not bad!" Professor Shangguan had a look of surprise on his face: "No wonder Class Leader Jiang Ju specially asked me to meet you, your comprehension ability far exceeds that of more than ninety-nine percent of smart people. (To be continued......)
