Seventy-year-old book: The villain Zaizai’s best mother

Xia Mingshuang didn't understand this, but she was very curious and asked Gu Yunshan what a water wheel pump was and how it worked.

"Is it cheaper than electricity and diesel?"

Gu Yunshan: "That's much cheaper. The water wheel pump is powered by water energy."

Xia Mingshuang said in surprise: "Oh, that's environmentally friendly and energy-saving, just like wind and solar energy."

Gu Yunshan lowered his eyelashes and looked at her, "You know a lot."

Xia Mingshuang said proudly: "That's right."

Although we are liberal arts majors, we have also studied science. Besides, having decades of experience in advanced technology has broadened our horizons.

Dr. Lou was also very interested in this. After all, he had studied science and engineering and was a man. He had a natural curiosity about machinery. "Yunshan, tell us about it. I went to different areas in my early years abroad. I have visited and found that in some areas they use windmills to generate electricity, grind mills, and lift water, in some areas they use biogas for cooking and lighting, and in other places they use water power to generate electricity and weave cloth."

Hearing what he said, Doctor Qian and Da Zhuang's children were also very interested. Da Zhuang, in particular, had been obsessed with machinery ever since he assembled bicycles. Whenever he had something to do, he would like to repair Xia Ming's double-handled bicycle here and there.

Seeing them looking at him curiously, Gu Yunshan couldn't help but curl his lips.

He usually gives lectures to technicians. He has also held exchange meetings with big guys and given lectures. Although there are many professionals staring at him with approving eyes, none of the family is worshiping him with such eager eyes at this moment. Staring at him made him feel even happier.

Most of his work content cannot be disclosed to his family and is classified as confidential, but it is still okay to talk about water power, wind power, biogas and solar energy.

He is usually very studious. When he was not at home, he used to read various professional documents besides working. He also read some foreign language materials brought back from overseas by intelligence personnel, and learned a lot.

When he was talking here, Da Zhuang even took out a ballpoint pen and a small notebook and started recording, asking him to slow down from time to time so that he could record more clearly.

Gu Yunshan: "No need to record it, just understand it. Once you have learned physics and chemistry, you will gradually become familiar with it."

Xia Mingshuang had a small appetite, so he put down his chopsticks after finishing his meal and listened to their conversation.

She said: "Don't just say that you won't practice fake moves. We can build water pumps, biogas, and solar stoves for our village to make it convenient for us. There is no electricity in this house, and it is dark all day long. It’s really inconvenient.”

Forget about wind power for now, the cost is too high and the brigade cannot afford it.

However, according to Gu Yunshan, the water wheel pump is not bad, the cost is not high, and it can be used for 30 to [-] years without breaking down. It does not require much maintenance and does not require much follow-up investment.

Biogas can also be developed, and related industries can also be developed, but this requires energy and he has no time to do it. He can only wait and see whether Mingcheng Agricultural Bureau can do it.

In addition, he can help with a simple installation of the solar cooker.

Although he has never done it, he knows that the principle is actually very simple to do, but this thing is not that practical in his opinion.

If it is cloudy and rainy, the solar cooker cannot be used.

However, in the countryside, where the courtyard is large and there is room to put it, it is still possible to use a solar cooker. You can even install a solar water heater to boil water for bathing and washing clothes at home.

He enjoys improving the quality of life for his family.

When it came to solar water heaters, Xia Mingshuangke had something to say, urging him to hurry up because she wanted one very much.

Burning coal in the boiler is very polluting, and it is inconvenient for them to buy coal. Besides, other people's homes don't have it. Her home is fine for heating in the winter, but it is too eye-catching to burn it [-] days a year.

Doctor Qian was also very moved by what Xia Mingshuang said about the bathroom, "Our house is spacious. If it's inconvenient for you, we can put it in our west wing and open a door in the wall for you to come and go easily."

Xia Mingshuang: "Okay."

Er Zhuang immediately hit Da Zhuang with his elbow and winked at Miao Miao. If it is really built, then can they sell bathing tickets and let people come to take a bath at home?

He had inquired when he went to the county seat before and found out that a bathing ticket costs [-] to [-] cents. They don't sell it that expensive, so [-] cents is the price, right?

Even if it doesn’t cost [-] cents, then [-] cents is fine, right? If it doesn't work, just four eggs will do, and that's still profitable.

Solar energy costs nothing, water costs nothing, but the machine costs money.

Dad said, that machine actually doesn’t cost much.

Both Gu Yunshan and Xia Mingshuang knew the thoughts of several children, but they did not expose them. Gu Yunshan always respected the children's wishes and did not force them to learn or do anything. This was especially true for Xia Mingshuang. She would not suppress the children if they were willing to make money. After all, Erzhuang is the military man next to Lord Hong in the book and is a little expert at making money. It is natural that he loves making money at a young age.

When Xia Mingshuang went to work the next day, he first looked for Zhang Danping.

She took out a wide woolen hairband that she designed and asked her third sister to hook it up. The navy blue hairband had a few small blue and green flowers on it, making it elegant and chic.

Zhang Danping loved these hairpins and hairbands. She often bought them from Xia Ming. When she saw them, she immediately made signs on her head in surprise.

Xia Mingshuang helped her put it on and took out a small hand mirror to take a picture of her.

Zhang Danping said happily: "Sister Ming Shuang, you are really amazing."

Xia Mingshuang: "My third sister knitted this. How can I have such ability?"

Zhang Danping: "That must be your design. Just wait, I'll give you the money..."

Xia Mingshuang interrupted her, "Pingping, I give this to you. It doesn't cost any money."

She paid the third sister to buy it for Zhang Danping as a favor and to hire someone to do something.

Zhang Danping laughed and said, "Sister Mingshuang, are you okay?"

Xia Mingshuang said angrily: "Oh, I have to ask you to do something before I give you something, right? I haven't given it to you before?"

Xia Mingshuang is not a stingy person. He often gives gifts to Zhang Danping and Li Yaoyao, including Wang Jinling and Fatty Aunt.

Zhang Danping naturally knew it, so she hurriedly held Xia Mingshuang's arm and said with a smile: "Sister Mingshuang, I was just joking. By the way, all the brigade have been paying public rations recently. There is a lot of wheat at my uncle's place, and their grain management office also grinds flour. . Do you want to buy some secretly? Let’s give you more money instead of food stamps.”

Xia Mingshuang squeezed her and said with a low smile: "You are such a considerate and lovely person. Our production team gave me a lot of wheat in exchange this year, which is enough for me. But our production team has come to hand over public grain in the past two days. , I don’t know if there will be any trouble.”

Zhang Danping immediately understood what she meant, "Don't worry, sister, I'm going out to do some work today, and I'll stop by my uncle to say something."

Xia Mingshuang: "Thank you very much. I will make you a small chocolate cake later."

Fang Rong has some imported high-end chocolates, which are quite expensive. Xia Mingshuang also buys them occasionally to give teeth to the children, or to make small chocolate cakes to share.

Zhang Danping's eyes lit up, "Then I'm really looking forward to it."
