After coming out of the machinery factory, the four of them went directly back to the courtyard.
No way, such a large amount of raw materials still has some weight.
After arriving home, Gu Baozhu learned from her parents that the Song family couple had left after they left.
They have made an appointment to meet at the Friendship Hotel on Chang'an Street three days later.
The reason for setting the time three days later is because Gu Baozhu's three brothers are not in Beijing, and it will take some time to get back.
When Zhang Xiuying talked about her brother, Gu Changping made a face and expressed his dissatisfaction.
Zhang Xiuying ignored him and continued.
She said that the immediate relatives of the Song family would come, and only relatives and friends would be invited to attend the official recognition banquet.
Gu Baozhu felt that this was not necessary and was scolded by her mother.
Her mother said that only by doing this could the Song family show that they valued her.
If you just acknowledge your relatives without any explanation, then you don't take her seriously.
"Mom, my eldest brother has recently been able to get out of bed and walk around. I'll call him up when the time comes."
"Of course." Zhang Xiuying said matter-of-factly, "Your eldest brother is the most promising person in our old Gu family. With him here, he can also help us suppress the situation."
"No matter what, we can't let the Song family think that you are too high-minded."
Gu Baozhu was unhappy, "Mother, where did you think you were going? Even if we know each other, I will live with you from now on. Besides, our family is not bad either. There is no such thing as being too high."
Zhang Xiuying glanced at her, "People's words are scary."
"All right!"
Seeing this, Gu Baozhu could only raise her hands and surrender.
She understood what her mother meant, and she just wanted to tell the Song family that their Gu family were not real country people.
She is also a delicate girl who has grown up in the hands of the Gu family, and cannot be looked down upon by the Song family.
"Looking at you rushing out early this morning, you brought back so many iron lumps?"
"What are you trying to do? I heard from the SS that these iron lumps cost a lot of money."
Zhang Xiuying couldn't help nagging, "That's not how you spend money..."
"Mom, just keep an eye on it. Soon this pile of iron lumps will turn into treasures. Then you will know whether the money spent is worth it."
Gu Baozhu grinned and pushed her out without explaining.
"I'm in a bit of a mess here. You go out and chat with the sisters-in-law first, and I'll be busy first."
Zhang Xiuying nodded her head, with a look of helplessness on her face, "Okay, just go ahead and be busy, don't be too tired."
My daughter has loved tinkering with these iron knots since she was a child, and she has really come up with a lot of good things over the years.
So she is not surprised at all. She can even tinker with radios and bicycles. Her daughter is definitely very smart.
What Gu Baozhu wants to do is a remote control airplane, which is very simple.
However, although the materials are available, many of them cannot be used directly and need to be modified.
Then she discovered a problem. Although she had the tools, she could change some parts.
However, some parts still require some technical equipment to be modified. She has these equipments in hand, but she cannot use them.
Gu Baozhu held up her face and couldn't help frowning, she was careless.
If she went to Director Guo directly, he would probably kick her out!
what can we do about it?
Gu Baozhu thought for a while, and suddenly his eyes lit up.
She can exchange her technology for the right to use the laboratory. It just so happens that the current battery cannot drive this small aircraft, and she plans to make a new battery.
She could come up with a battery technology that is more advanced than what is on the market and exchange it with Director Guo for the opportunity to use the laboratory.
Well, she is really a clever little clever girl.
As for whether it will be shocking, don't worry.
The most indispensable thing in this era is genius. In addition, her performance in all aspects has been extremely outstanding. The development of a new battery does not seem to be too eye-catching.
Gu Baozhu did it as soon as he thought of it, and immediately went to his desk to write and draw.
Two hours later, a solar panel with a world-leading conversion rate appeared.
She doesn't know what the utilization rate of solar cells is today, but it will definitely not exceed 15%.
The solar cell now designed by Gu Baozhu has a conversion rate of up to 20%.
It's not that it can't be higher, but it's very achievable with the existing materials. Even if it's 20%, it's still a very difficult task to spread it over a large area.
In order to be able to use the machinery factory's equipment, Gu Baozhu also worked hard.
In addition to the design drawings, she also wrote down some relevant information, and then packed up and prepared to go to the machine factory.
"You just came back not long ago, and you want to go out again?"
Zhang Xiuying looked at the bright sun outside and couldn't help but frown.
If you go out on such a hot day, you won't get heatstroke?
Gu Baozhu chuckled and said, "It's a small matter. I'm going out. You don't have to wait for me at noon. I may come back later."
"Then what will you do for lunch?"
"This is simple, just go to the hotel to solve it when the time comes."
Zhang Xiuying didn't say anything after hearing this. She just told her to be careful before continuing with the work at hand.
She is also restless, and since this is her own house, she can clean it up even more easily.
Gu Baozhu went out, hailed a taxi and went straight to the first mechanical department.
"why is it you again?"
The old guard could not help but wonder that the little girl had left the machine factory just two hours ago.
Why did this come back again? Could it be that you are still looking for the factory director?
"Uncle, I'm looking for Factory Director Guo."
"Little girl, didn't you just come here?"
Gu Baozhu nodded, not minding the old man's curiosity, and explained in a leisurely manner, "Isn't it because I suddenly remembered that I still had something to do, so I came here in a hurry? Can you help me?"
Would you like to notify Director Guo?"
"Just say it's urgent for Gu Baozhu to find him." She felt that solar cells were indeed an urgent matter.
"Then wait a minute, I'll go find the factory director now."
Gu Baozhu was not an employee of the machinery factory and could not enter or leave the machinery factory at will, so she didn't care and nodded.
Then she saw the old man walking quickly, but within a few minutes he disappeared.
The old man was very fast and came back in less than fifteen minutes. Following him was not Factory Director Guo, whom she had longed for.
"Comrade Gu, I heard Comrade Luo say that you have something urgent to ask me for?"
"Yes, it is indeed extremely urgent." Gu Baozhu looked around and couldn't help but frown, "Director Guo, are you sure you want to say it here?"
Guo Maoling was stunned. Before he came out, he thought that the little girl had regretted her decision and wanted to return all the spare parts. For Lao Kang's sake, it was not impossible.
But I didn't expect that it didn't seem to be the case. Does this little girl really have something urgent to do?
"Can't we say it here?" He blurted out subconsciously.
Gu Baozhu shrugged indifferently, "It's not impossible, but it's just a design drawing of a solar panel, and it's not a very high-tech technology."
"Oh, solar panels, indeed..." Guo Maoling stopped suddenly in the middle of his sentence and looked at her subconsciously, "Comrade Gu, you said, you just said..."
Gu Baozhu nodded, "I did say solar cells..."
"Let's go in, let's go in and talk!"
How could Guo Maoling let her continue talking about this kind of technical issue, or about solar cell technology, whether it was true or false, he couldn't help but be cautious.
