When Qin Mingsheng saw the light bulb light up, he couldn't help but let out a big breath.
Although he has operated countless experiments, this is the first time he is using a power generation panel made of regular materials!
Under everyone's attention, Qin Mingsheng climbed down the wooden stairs from the roof, walked to Professor Li's side, and bowed to everyone.
Professor Li said with a smile, "I believe that everyone has a lot of curiosity in their hearts. Then everyone can raise their hands and ask questions, and we will give you an answer."
"Comrade Qin, I want to ask, why did the light bulb wait for several minutes before it came on?"
In the crowd, someone asked a question that everyone was curious about.
Qin Mingsheng replied calmly, "It's very simple, because it takes a little time for the power generation panels to gather solar energy, and the reason why the light bulbs lit up a little slow just now was because the power generation panels were placed on the roof.
If we usually put the solar panels on the roof for a long time, then we can switch on and off the power at any time without waiting. "
Question 2: "Comrade Qin, I would like to ask, since this is called a solar panel, can it generate electricity even on cloudy days without the sun?"
Qin Mingsheng: "It is possible to generate electricity on cloudy days, but the amount of electricity generated is relatively small. At present, the technology of power generation panels is still in the preliminary research and development stage. If it encounters rainy days or cold winters, the normal operation of power generation panels may be affected. "
Question 3: "Does this mean that Comrade Qin has other technical changes in the future?"
Qin Mingsheng: "Yes, the solar power panel is just a medium for energy conversion. The utility of power generation is not stable enough. It only has the function of starting the power supply, but it has no function of storing electricity. Therefore, the next step is to develop a solar battery.
If there is a battery, with enough energy stored, even if it rains, we can continue to use electricity for eight hours! "
"Wow!"
The crowd was in an uproar again, looking at Qin Mingsheng with great admiration.
There is no doubt that Qin Mingsheng at this moment is a shining body with golden light in the eyes of everyone!
Afterwards, someone asked a few more questions, and Qin Mingsheng answered them perfectly. It wasn't until eleven o'clock that the experimental observation meeting ended successfully.
But it is not that the experiment was successful. Even if it is over, there is still a lot of work to be dealt with and negotiated in the future.
Therefore, Qin Mingsheng spent another two days interviewing government leaders, and had professional technical exchanges and technical guidance with the scientific research institute.
At the same time, he also gave a professional public speech class at the school, and conducted related handover work with the person in charge of the machinery factory.
Finally, on Saturday morning, I got on the bus back to the county seat!
If he doesn't go back to the village to meet his wife, he will go crazy!
Now that the experimental project has been completed perfectly, he can give his wife an explanation when he gets home.
He hasn't seen his daughter-in-law for more than two months, especially now that her daughter-in-law is pregnant, and he doesn't know how she has been at home for more than two months?
Although he communicates with his daughter-in-law once a week, he is afraid that his daughter-in-law will report good news instead of bad news, so he does not tell him the truth.
Originally, it was a lot harder for a woman to be pregnant, and she was not by her side. Although there were other family members accompanying her, she couldn't take care of her personally.
If there is any inconvenient place at night, there is no one around to take care of it.
For example, when the eldest sister-in-law and the second sister-in-law are pregnant, and there are at least two brothers waiting by her side, even if his daughter-in-law has a great system, the system cannot replace the existence of a husband.
So whenever he thought of his daughter-in-law being alone at night, he felt very sad.
The only thing he can do is to pay more attention to reading and study, finish all the following courses in advance, and strive to graduate as soon as possible!
It is now the second semester of the junior year, and he has already started to study the courses of the last semester of the senior year. With Professor Li as a tutor, he can ask questions at any time if he does not understand. In addition, he has also watched many daughter-in-law's His professional books expand a lot of knowledge.
As for the second semester of the senior year, it is basically the stage of arranging the study by oneself, and then submitting a professional thesis before the end of the semester, even if it is the academic summary report of the four-year university.
Qin Mingsheng is now eager to liberalize as soon as possible and finish his studies ahead of schedule. Although he cannot get his graduation certificate early, he can be very flexible and free in time.
Then, he can accompany his daughter-in-law while making experimental inventions, so he doesn't have to be tied to the school.
As long as he has made inventions, national organizations and related institutions will give certain awards, so he can make money to support his family as soon as possible.
He has already thought about his future career plans.
In the past, all he wanted was to work in a public unit after graduation, and then shine in his post to make his own contribution to the construction of the country.
But things are different now, he has Yiyi!
His family Yiyi is not an ordinary woman. The time machine she has is like a time bomb. He doesn't know when the time tunnel will open.
He was afraid that the woman he loved would suddenly disappear, just as she suddenly appeared in front of him.
Therefore, he didn't want to leave her too far, and he didn't want to be separated from her for too long.
If it weren't for the ability to create better living conditions for her, he would definitely not be able to bear the days of studying in a different place.
As a man, a husband, or even a father, he has the responsibility to create a better future for his wife and children. Whether in terms of reputation or material interests, he wants to give his wife and children a better future as much as possible. .
After he graduated, he was no longer going to work in the public sector. He was going to hang up a job and make experimental inventions, just like his daughter-in-law is now.
That way, he will be able to accompany her for a long time.
The bus staggered all the way, and Qin Mingsheng's thoughts were full of flying.
**
Early in the morning on Saturday, the Qin family took action collectively!
This time, everyone in the Qin family was more serious and solemn than the one when Ma Long came to the door.
However, the Zhao family will only come to the door tomorrow, and everyone will start cleaning up today.
This attitude is obvious enough and serious enough, right?
As for Zhao Dongliang, after having breakfast, he went back to the county by car, and plans to bring his parents to the door tomorrow.
Huang Qiuhua gathered everyone in the family and distributed them one by one.
"Boss, second child, every room in the house, especially the outside places like the stove and the main room, every beam and corner, must clean up those cobwebs!"
