Sixty-year-old only child: The system taught me how to become rich

"Solar energy?"

Gu Xian was very surprised and his voice raised unconsciously.

When Gu Xian went to college, he studied science. Although he didn't do research in the end, he still knew about solar energy.

This is solar power generation!

Even those developed countries that are far ahead in technological level in the world have not completely conquered this technology.

If Gu Ning could learn this technology, it would be of great help to the country.

If solar power generation can be conquered, perhaps the current situation of no electricity in many parts of the country can be solved, and the country can also earn a lot of foreign exchange by relying on this technology.

You must know that the country is now technologically blocked by those developed countries.

Therefore, even if they are very poor and cannot solve the basic necessities of life for the domestic people, they are still trying to export large quantities of materials in exchange for foreign exchange, and then purchase the machines they have eliminated from other countries.

You know, even the machines that have been eliminated by those developed countries are still at a level that cannot be reached domestically.

Thinking of this, Gu Xian began to look at this big guy again, but this time it was not with scrutiny and satisfaction, but with surprise and excitement.

No wonder I haven't seen the wires plugged in before.

Gu Xian thought that Gu Ning didn't take it out, but he didn't expect that there was no wire plugged in at all.

After looking at the solar refrigerator with novel eyes, Gu Xian asked:

"Ning Ning, how does this refrigerator use solar energy to charge? Do you put it directly under the sun to let the sun shine?"

Before Gu Ning could speak, he was interrupted by Gigi Gigi who walked into the room.

"What are you two, father and daughter, doing? And what does this big guy do? Ning Ning, is this the reason why you woke us up this morning?"

Gigi Lai asked.

Originally she was sleeping, but Gu Xian's sudden scream woke her up. I wanted to continue sleeping, but I couldn't fall asleep as I was tossing and turning on the bed, so I simply got up and came out to see what Gu Ning and Gu Xian were doing.

When she just walked outside Gu Ning's room, Gigi Gigi saw the solar refrigerator that shouldn't be in the room.

When she first saw this solar refrigerator, Gigi Lai was shocked. But she quickly realized that it was probably a new item from the 001 reward, so she made the inquiry just now.

Gu Ning nodded excitedly and replied:

"Yes, Mom. Did you know? This is a refrigerator! And it's solar powered! 001 rewarded it to me this morning. I really wanted to try it first. But I couldn't open the door or use it, so I sent you Wake up."

"Solar-powered refrigerator?"

Gigi Lai couldn't help but ask.

Gu Xian watched quietly from the side, not in a hurry, and let his daughter explain slowly, which was just a good opportunity to practice her expression skills. This kind of thing should start from daily life.

Gu Ning replied again:

"Yes, Mom. That means this refrigerator can be charged by the sun. There are two solar cells in the refrigerator. As long as you put them under the sun, they can generate electricity. A fully charged battery can power this refrigerator continuously. Use it for several months.”

Now Gigi couldn't help but be as shocked as Gu Xian. When she heard the name of this refrigerator, she had some expectations.

It wasn't until her daughter admitted it in person that she confirmed that the refrigerator was indeed what she thought, using solar power generation technology.

At this time, Gigi Lai's eyes became hot when she looked at the solar refrigerator.

This is a technology that currently none of the developed countries that are far ahead in technology in the world have been able to master it!

She and Gu Xian were indeed a couple, and both of them immediately thought of how much Gu Ning could help the country by learning this skill.

You know, although 001 comes from the interstellar world and has a much higher technological level than here, it has never rewarded Gu Ning with anything beyond the level of this era.

Usually, the most rewards are small items such as cameras. At most, the workmanship and functions are superior to the cameras currently available on the market, but in the end, they are still cameras, not much different.

This is the first time that a solar-powered refrigerator is rewarded!

Gu Xian and Li Zi both had some doubts in their hearts, but neither of them asked.

After Gigi Lai was surprised, she asked:

"Ning Ning, do you know how to take out the solar power battery and use it?"

Gu Ning nodded happily and said:

"I'll demonstrate it to you again."

After saying that, Gu Ning ran to the back of the refrigerator, opened the lid of one of the two small grooves, and took out the solar power battery inside.

Fortunately, the groove for placing the battery is relatively low, so Gu Ning can reach it easily.

She held the battery in both hands and handed it to Gu Xian and Gigi Gigi to see as if it were a treasure.

Gigi Gigi took the battery from Gu Ning's hand and looked at it carefully. She wasn't a professional after all. She just felt that the battery looked very high-tech, but she couldn't tell what it was like.

Gu Xian also came up and looked at the battery. Similar to the batteries currently used, this battery is significantly larger, looks heavy, and has a good texture.

The battery is completely black and slightly shiny in the sunlight.

The two people looked around the battery and looked at it again and again, but they didn't see anything interesting about it.

The initial excitement passed, and the two finally gave up their research.

The operation method of taking out the battery is very simple. Gigi knew it after Gu Ning did it just now.

She followed Gu Ning's previous actions and put the battery back into the groove and said:

"We'd better use this refrigerator first. The battery has been put back now. Ningning, do you know where the switch is?"

Just after asking, before Gu Ning could answer, Gigi noticed a small black button on the back of the refrigerator.

She pointed to the black button and asked:

"Ning Ning, is that a switch?"

Gu Ning nodded and said:

"Yes, that button is a switch. There is a sign on it. Mom, just press the button to the side that says on."

Gigi Lai nodded to express her understanding. Just as she was about to go over and turn on the switch, Gu Xian beat her to it.

After the switch was pressed, the three of them waited quietly, but found that the refrigerator did not respond at all.

Gu Xian and Gigi Lai felt a little strange, worried that something was broken. After all, the refrigerators they used before made noises when they were operating. This is basically the case with any machine. But when they thought it was sent by the system, they felt that it was not a big deal.

Gu Xian frowned, looked at Gu Ning and said:

"Ning Ning, can you ask 001 if this refrigerator is broken? Otherwise, why is there no sound of the machine running?"

Before Gu Ning could ask, 001, who had already heard Gu Xian's question, gave the answer.
