Chapter 443： 443, the light bulb is on!

At 9:30 in the morning, Professor Li walked to the installed microphone and spoke.

"Good morning, everyone, welcome everyone to come to the provincial university to witness this historic moment! I think everyone must have a lot of questions in their hearts, does the sun's light and heat really contain energy? Can the sun's energy really generate electricity?

I think no matter how much I explain, it is better for everyone to see it with their own eyes, and it will be more real and profound! Then, we will show you the formal experimental operation on the spot! "

So, everyone saw someone put up a wooden ladder, and then saw someone lift a silver-gray board out of the room.

It is said to be a board, because the front that everyone sees is a flat board, which is very smooth and reflects light vaguely.

Because of the line of sight, everyone couldn't see what was under the flat board. In short, the material of this flat board looked very unique and novel, not wood or cardboard.

Then, I saw a man carrying the silver-gray board behind him, climbed up the wooden ladder step by step, and placed the silver-gray flat board on the roof of the Great Hall.

A black wire was torn out from under the flat board and was thrown to the ground by the man. Then, Professor Li picked up one end of the black wire and connected it to the power board on the table.

At this moment, a wooden pole is tied to the foot of the table, and a light bulb is tied to the top of the wooden pole!

The reason why the light bulb is supported by a long wooden pole is also to facilitate everyone to see the starting of the power clearly and clearly!

At this moment, everyone watching couldn't help holding their breaths, staring at the light bulb on the wooden pole.

Although everyone does not know the principle of solar power generation, the power cord of the light bulb has been plugged into the power board, and the switch of the power board has also been turned on. They can still understand this operation.

However, the power strip has been turned on, but in the next second, everyone did not see the light bulb light up.

"What's the matter? Why isn't the light bulb on?"

"Isn't it? Failed?"

"How did you do it? The experiment didn't work, so let everyone watch the results?"

"Let me just say, solar power is simply impossible."

"Some people are still too eager for quick success."

"I think this argument is very interesting, at least no one has put forward it yet."

........

Standing under the wooden ladder, Wu Zhihua and the others also showed nervous expressions.

A few people in their dormitory came here specially to help today. They were responsible for the on-site transportation and lay-off work. As good brothers, at such a critical moment, of course they came to support Qin Mingsheng.

Before, they were also surprised or unacceptable to Qin Mingsheng's idea of ​​solar power generation, but seeing that he was not joking, but seriously wanted to make this invention, everyone put away their contempt.

Although they still retained a bit of disbelief in their hearts, they still gave a lot of support and encouragement to the actions of the good brother.

During this period of time, they also helped Qin Mingsheng to travel a lot, just to make some investigations for him, and to inquire about some trivial matters such as experimental materials.

It can be said that they have also participated in this experimental project, so they also have feelings and dedication to this invention.

Therefore, no matter in terms of public and private, or in any aspect of affection and reason, they all hope that Qin Mingsheng's experiment will be successful.

Hearing everyone's discussion at this moment, a few people couldn't stand still.

Sun Zhenyu frowned, "It won't really fail, will it?"

Wu Zhihua snorted, "What are you saying to be disheartened!"

Feng Shengli said firmly: "We should have confidence in Mingsheng."

Yang Weixing nodded in agreement, "Yes, Mingsheng is the most potential and capable person in our physics department."

Li Dayong was a little worried, "Why haven't the light bulbs turned on yet?"

Xiang Dong looked at the crowd calmly, "Professor Li is not in a hurry, what are we worried about?"

So, several people looked at Professor Li in unison. Sure enough, at this moment, Professor Li looked calm and relaxed, as if he was very sure that the light bulb would turn on.

Even if there are more and more doubts around, it is not affected at all, just staring at the light bulb intently.

Just when the audience was about to lose their patience, someone suddenly shouted, "It's bright!!"

Everyone immediately glanced at the light bulb, and sure enough, the light bulb hanging on the wooden pole lit up. Although the light was not very obvious during the day, everyone still clearly saw that the light bulb was on.

"It's really bright!"

"Oh my, this is amazing too!"

"Can the sun's heat really generate electricity?"

"Isn't it connected to another power source!"

"It shouldn't be possible, and there is no wire connection around."

"This invention is simply amazing."

Different from the admiration of the onlookers at provincial universities, what the scientific research experts and professors saw was not the surprise of the invention, but the deep meaning behind the invention.

"Sure enough, there are talented people in the country!"

"The country's scientific research road has a successor."

"It's the pride of our country."

"Now, look at other countries laughing at you!"

"There are times when we, China, are at the forefront of the world."

"It is foreseeable how much sensation this experimental project will cause when it is launched."

The corner of Professor Li's mouth was smiling, and his expression was full of pride.

In his lifetime, he was able to participate in such a meaningful, valuable and great experimental invention, and he really had no regrets in his death.

"Comrades, please allow me to introduce this experimental invention, the solar power generation panel! The electric current is generated through the conversion of light, heat and energy, thereby starting the power supply. The flat panel you just saw is the power generation panel.

With this power generation panel, you don't need to install lines at all, and you don't need to rely on a power station. You only need to place a solar power generation panel on the roof, and you can collect solar energy through this power generation panel, and then generate power! "

"Wow!!"

Everyone exclaimed in amazement and clapped their palms.

Professor Li raised the corner of his mouth in satisfaction, pointed at Qin Mingsheng, who was still guarding the power generation panel on the roof, and introduced loudly through the microphone, "Comrades, the one standing on the roof at the moment is the inventor of today's experiment, Qin Mingsheng. !!"

The whole crowd burst into thunderous applause. Everyone looked in the direction of Qin Mingsheng, smiling and applauding excitedly, with surprise, admiration, admiration, admiration...
