Technology and life: starting with solar cars

Chapter 2 Glass
Han Guofu Guang Glass Factory.

Liu Yun was released by the security guards after showing a small goal of several hundred million.

"Hi, Grandpa Cao, I'm Liu Yun from Huaxia Yunfan Technology. I'm here to ask you to make a batch of glass." After speaking, Liu Yun took out his business card and put it in front of Cao Qingyun.

Cao Qingyun said that he had never heard of this company at all, so he picked it up curiously.

Good guy, the business scope written on the business card turned out to be car sales.A technology company sells cars, no matter how you think about it, it feels strange. Isn't this a typical trickery.

He asked Liu Yun curiously: "What kind of glass do you plan to make?"

"It's like this. Our company plans to develop solar cars, so I was sent here. The main purpose is to make a batch of glass to improve the efficiency of light utilization."

Liu Yun's face didn't turn red when he spoke, and his heart didn't beat.He is currently the only one in his so-called company, so it can be said that it is not ordinary, and it is nonsense to send him here.

Before coming here, he directly increased the company's paid-in funds to 1 trillion based on the idea that the system's money should not be used in vain, so that partners would feel more at ease.

Especially in cooperation with large companies, the strength still needs to be shown a little bit.

"Okay, young man has ambition. At present, there is no solar car in China. I don't know what your idea is?"

"I do have an idea at the moment. I want to collect solar energy as energy to achieve fast charging of cars. Compared with gasoline cars that consume oil and new energy cars that are troublesome to charge, it has some advantages."

Cao Qingyun nodded, and called the designer Wang Xuan over.

Soon, a man in a blue factory suit and leopard-print reading glasses entered the office.

Wang Xuan stood in front of Cao Qingyun and asked, "What does the boss want from me?"

Cao Qingyun didn't speak, and pointed to Liu Yun next to him.

Liu Yun smiled and said, "Hello, designer, I'm Liu Yun, and I want to make some glass, so I'd like to ask Boss Cao to call you over."

Wang Xuan nodded, put the A4 paper held in a clip on the table, took out a pencil, and asked without raising his head: "Tell me about your requirements, and then I will design according to your requirements. See if you are satisfied."

“我想制作一块长1米4、宽1米5的玻璃，其中宽的10厘米在两边各留5厘米与车体连接用。在1米4×1米4的表面尽可能多的雕刻出凸透镜，要求所有的凸透镜的曲率半径一样，但是焦距尽可能的保持在30厘米以内。”

The radius of curvature of the lens: the front and rear surfaces of the lens are curved, and the two complete surfaces are equivalent to a part of a sphere, so the sphere must have a radius, which is the radius of curvature of the lens, usually divided into The respective radii of curvature of the front and rear surfaces.

Liu Yun asked to design a plano-convex lens, that is, a lens with only one side convex.

Focal length: When light passes through the lens, a minimum point appears on the plane, and the distance between the minimum point and the lens is the focal length.

For the size of the glass, Liu Yun also has his own considerations.Take a certain brand of car as an example, the official size of the brand is 4688*1786*1472mm.

宽度按1米8算，留出20厘米的活动空间，剩下1米6来放置太阳能板足够用了。考虑到光在不同的时间有可能不直射，制造宽1米4的聚光玻璃即可。

The length can't be too long, it can only be in the area between the trunk and the front windshield.And in order to better absorb solar energy, the roof must be flat. There is no doubt that once the roof is too flat, the resistance will be greater when the car is running, which means that this kind of solar car is not suitable for rich people who play sports cars.

Wang Xuan was a little dazed. It was the first time he saw an auto glass manufacturer making convex mirrors.It is said that this kind of simple convex mirror can be manufactured in any small factory, and there is no need to come to China's largest glass factory to manufacture it.

Facing the wrinkled Wang Xuan, Liu Yun added: "I came to Fuguang Glass Factory for two reasons. One is that Fuguang Glass Factory has a large scale and can carry out large-scale production, because we may expand the demand in the future This is very important. Second, we have high requirements for glass technology, and the size, radius of curvature, and convex lens parameters of each piece of glass must be consistent, and other small factories tend to make the parameters uneven.”

Wang Xuan nodded, then lowered his head and immersed himself in the ocean of design.He took a pencil and rubbed while drawing on the paper. On the paper were one symbol after another that Liu Yun didn't understand, technical terms such as R and L.

After a few minutes, the drawing was completed, and he went straight to the glass production workshop with the designed drawings in his hands.

After Wang Xuan left, the office fell into silence.The main reason is that Liu Yun and Cao Qingyun don't know each other, and there is no common topic due to the large age span. Apart from work, there is really no personal matter to talk about.

Cao Qingyun flicked his phone boredly, and checked the information of Han Guo Yunfan Technology by the way.

If you don't check, you don't know. If you check, you will be shocked.Not to mention anything else, he was stunned by the fact that the paid-in capital of 1 trillion was the only item.

The so-called paid-in registered capital refers to the funds that have actually been paid, which is similar to the nature of the guarantee deposit, and is the opposite of the subscribed registered capital.Subscribing registered capital is intended to be paid in the future, and the funds that have not been paid yet, the specific payment time is written in the company's articles of association.

The paid-in registered capital of 1 trillion yuan has caught up with many domestic oligarchs, which is really scary.

Looking at the company's registration time, it was actually a few days ago.

Could it be that this is a company actually controlled by the United Nations?Then Cao Qingyun denied this idea.If it is really a technology company controlled by the United Nations, there is absolutely no need to come here to make glass with the technology of the United Nations.

Time passes second after second in the "didi di" of the clock.

In just half an hour, the designer Wang Xuan came back in a hurry with the designed glass plate, and he came and went in a hurry.This kind of anxious personality is a common fault of designers, who don't like to waste time on meaningless things.

He put the finished glass plate on the table, "Do you see if this model meets your requirements? It has a total of 28×28 convex lenses, its radius of curvature is 1000, and its focal length is"

He said a lot of technical terms that Liu Yun didn't understand. Liu Yun was afraid of being embarrassed, so he could only nod his head from time to time.

Turn your gaze to the glass plate.The glass plate is flat on one side and convex on the other, the surface has been polished to a shiny finish, and the glass between each convex lens has been removed.

The table below can be clearly seen through the glass, and there are no obvious defects such as particles and bubbles in the middle of the glass, which shows that the quality of the glass is very good.

Satisfied, Liu Yun took the glass panel and came under the sun, which was at 2 o'clock in the afternoon when the sun was at its most poisonous.

Sunlight shines on the newspaper prepared by Liu Yun through the lens, and the newspaper presents a dense pile of light spots.The burning newspaper with these light spots for 1 second has a burning focus, and after another 2 seconds, the newspaper is ignited.

It's so terrifying.

Liu Yun was very satisfied with the effect, and said to Wang Xuan, "Let's manufacture another 1 pieces according to the parameters of this glass plate."

Wang Xuan kindly reminded: "This glass plate is not cheap, you need one."

Liu Yun interjected directly:
"Stop, don't mention money to me, I'm not interested in money."

"But I'm interested in you. I don't know if you'd like to change jobs and come to my company. I'll give you 100w a month, including room and board."

Cao Qingyun's face was a little dark.Is it really okay to dig him in front of him? If it weren't for Liu Yun's dedication to developing technology, he would have to drive Liu Yun out.
