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

This refrigerator can be used without plugging in because it is a solar-powered refrigerator.

There is a solar power battery in the refrigerator. If you put the battery under the sun, it will use the energy of the sun to generate electricity, and then store the generated electricity in the battery.

Then put the charged battery back into the groove of the refrigerator, and the refrigerator is ready for use.

A fully charged solar-powered battery can last the refrigerator for several months with uninterrupted use. But it only takes an hour to charge.

This refrigerator has a total of two solar power batteries, one is for daily use; the other is a backup in case of any accidents, or the solar power battery can be replaced if it breaks down.

So there are two grooves on the back of the refrigerator to store two batteries respectively.

The two solar power batteries in the refrigerator are now fully charged and do not need to be charged for the time being.

After learning about this solar refrigerator, Gu Ning was surprised.

She had never seen a solar-powered refrigerator and had no idea that the sun could be turned into electricity.

Gu Ning looked out the window. It dawned early in summer, and now it was already bright outside. Sunlight shines into the room through the glass windows.

Gu Ning stared blankly at the sunlight shining into the room, and stretched out his hand to feel it, his eyes filled with disbelief.

She asked 001 again:

"001, how can sunlight turn into electricity? They are obviously two completely different things. Electricity is white, and sunlight is golden. My mother told me that thunder and lightning are electricity. I usually see thunder in the sky, and the electricity is not like sunlight. It doesn’t look like it either.”

Its host is still too young and has not learned knowledge to this extent. It is normal not to understand it.

001 explained without any impatience:

"Host, electricity is a kind of energy, did you know?"

Gu Ning nodded and said:

"Yes, I know this. I learned this knowledge before when I was studying physics."

001 continued:

"Then you should know about electric lights, right? They are the ones used in your home now."

Gu Ning still nodded and said:

"I know. Electric lights use electricity. They can emit light and are very bright at night."

001 continues to explain:

"So electricity can be turned into light. Electricity is a kind of energy, and light is also a kind of energy. Since electric energy can be turned into light energy, why can't light energy be turned into electrical energy? Isn't sunlight a kind of light energy? Of course solar energy There are some differences with light energy, but these hosts can be understood later."

After hearing 001's explanation, Gu Ning understood.

She had studied electrical energy and light energy before, but not solar energy, because 001 planned to let her learn solar energy alone later.

But she still understands these simple concepts, not to mention that 001 explains them in such detail.

Gu Ning was very happy after having her doubts answered.

But then she realized she couldn't use the refrigerator. As for the reason, she was too short to reach the refrigerator door handle.

Even if you pull up a stool and stand on it to solve the height problem, it still won't work. Because she was too weak to open the door.

This time she was stumped.

Gu Ning glanced at the watch on his hand again. After fussing with it for so long, it was already past seven o'clock.

Gu Ning rolled his eyes and then made a decision.

She ran outside the door of Gu Xian and Li Zi's room. The door was closed and she couldn't open it. There was no other way, so Gu Ning could only knock on the door and shout loudly to wake them up.

She felt that Gu Xian and Gigi Gigi had been sleeping for a longer time, and she really couldn't wait to try the refrigerator, so she just kept waking Gu Xian and Gigi Gigi.

Mom and dad probably also want to take a look at the refrigerator. Gu Ning thought this and suddenly felt more confident.

With her perseverance, Gu Xian and Gigi Lai successfully woke up.

When they first heard the noise, Gu Xian and Li Zi just covered their heads with quilts, trying to drive out the noise.

But it was no use at all, these sounds kept going into my ears. Unable to bear it anymore, Gigi Gigi pushed Gu Xian and motioned for him to open the door.

Gu Xian was pushed, but he didn't move at all, and he didn't want to get up and open the door.

Seeing that he didn't move, Gigi Gigi pushed him hard a few more times.

Gu Xian had no choice but to get up from the bed slowly and opened the door with a curse:

"Gu Ning, you better be in trouble. Otherwise, if you knock on my door so early in the morning, I will really beat you up."

Gu Ning was not afraid of the threats from Gu Xian at all. She knew that Gu Xian was just talking and was not willing to hit her at all.

So when Gu Xian opened the door, Gu Ning was still smiling.

Gu Xian's face was expressionless, and his whole body exuded a low pressure.

He looked at Gu Ning and asked fiercely:

"Tell me, what's the matter with you? Why are you knocking on the door of our room so early in the morning?"

Gu Ning's eyes were bright and she said loudly:

"Dad, come to my room with me quickly. 001 rewarded me with a good thing. I promise you will like it."

Gu Xian was dubious and let Gu Ning pull his pants down and followed her into her room.

As soon as he entered Gu Ning's room, he saw a big guy.

Gu Xian felt that this big guy looked familiar. It looked a bit like the refrigerators he had seen before, but it looked much prettier and bigger than the ones he had seen before.

he asked:

"Is this the reward you were talking about? What is this for?"

Gu Ning said excitedly:

"This is a refrigerator! Dad, do you know about refrigerators?"

Hearing this, Gu Xian's eyes were slightly surprised, but not as surprised as Gu Ning imagined.

He suddenly realized:

"It turns out to be a refrigerator. I just said it looks like a refrigerator I've seen before."

Now it was Gu Ning's turn to be surprised:

"Dad, do you know about refrigerators?"

Gu Xian nodded and replied:

"Yes, not only have I seen it, I have also used it. Your grandparents had one at home before, but it was not as big as this one, and it was not as beautiful."

By now Gu Xian was completely awake. He looked around the big guy up and down and was very satisfied:

"Yes, yes. You can freeze the ice cream and eat it in the summer. You can also cook more dishes in the summer, and put the uneaten ones in the refrigerator, so you don't have to worry about them spoiling."

As he spoke, he frowned again:

"No way. This refrigerator needs electricity, and it uses a lot of electricity. Our building should be able to withstand such a large voltage, but the electricity consumption is hard to explain. And this refrigerator looks different from the current refrigerators. ah."

Gu Xian rubbed his chin with one hand and said:

"It seems that we have to find a suitable excuse to show this refrigerator in front of people, otherwise it won't be usable."

Now Gu Ningke found an opportunity to show off, and she said excitedly:

"Dad, this refrigerator doesn't need to be plugged in. It runs on solar energy!"
