There are not many good things in the scrap purchase station. If you want to find a bargain here, you will definitely be a dream.

The uncle was also thinking about whether he could find some used steel and iron products, or discarded bicycle parts at the scrap purchase station, so he bought it and assembled a bicycle himself.

But there is no chance.

There is no steel or iron product at the scrap purchase station, and there is no bicycle parts.

These things have long been recycled by those factories and have no chance to reach the scrap purchase station.

The uncle finally found only a few pieces of discarded wires and very small metal pieces at the acquisition station, which were not worth much. He gave three cents to the person who managed the scrap acquisition station and took away everything.

However, Zhao's father found a few good wood from the scrap purchase station and bought them all.

The father and son were extremely happy. When they returned home, Zhao's father bought a large piece of pork and even packed a meat dish and a dozen meat buns in a state-owned hotel.

When they returned home, the father and son were warmly welcomed by the family.

Well, the others did not welcome them, but the meat dishes and meat buns that the two brought back.

Zhao's mother cooked a pot of mixed grain porridge, returned the meat and vegetables to the pot, and added a lot of potatoes. The meat and vegetables that originally had only one bowl were served, and when they were served, they could only be filled in a bowl.

The whole family started to eat supper around the dining table, each with one meat bun, and everyone was full of oil.

At the dinner table, Zhao's father told me about receiving work in the city. The others reacted even more than Zhao's father at that time. He was so happy!

Even a few children were very happy.

They are all smart children. Knowing that they have work, they can eat meat.

After receiving the advice of parents, the children would not talk about their own work outside, and they were afraid that they would not be able to eat meat in the future.

The more my three sisters-in-law look at my younger brother-in-law, the more satisfied they are. As the man said, my younger brother-in-law is the lucky star of the family!

The uncle swallowed the potatoes in his mouth into his stomach and said to Zhao's mother: "Mom, after dinner, please give me a few more potatoes."

"Okay." Zhao's mother responded with a smile, and didn't ask anything to her younger son with potatoes. She thought that it must be that her son wanted to eat roasted potatoes.

After dinner, Zhao's father anxiously took his three sons to make the washing machine. In order to facilitate the three of them to do their work, Zhao's mother endured the pain and took out two oil lamps to put them in their work room.

The uncle of the junior teacher asked Mrs. Zhao to cook the potatoes that Mrs. Zhao gave him.

Mother Zhao cherishes her younger son, and the potatoes she gave to her junior uncle were the largest.

The uncle of the junior teacher entered his room with the cooked potatoes and found the light bulb wires and metal pieces he bought today.

The metal sheets were carefully selected by my uncle, and it happened that in addition to zinc sheets, they were copper sheets.

Insert the zinc and copper slices into the potatoes, connect the wires, and a green and efficient biobattery is ready.

It's that simple.

In fact, raw potatoes can also be made into batteries, but the effect is not as good as cooked potatoes.

After the potatoes are cooked, a coating will be produced on the surface. This coating is the key to the potato battery and can enhance the salt bridge capacity, making the power generation capacity of cooked potatoes about ten times stronger than that of raw potatoes.

The uncle of the junior master connected the made potato batteries with the light bulb. The light bulb lit up, which made the uncle's house extremely bright.

Well, this brightness is a comparison.

The brightness of the light bulb cannot be compared with the brightness of modern lamps, but compared to kerosene lamps, it is much brighter.

Zhao's mother and three sisters-in-law found that the house of the junior teacher suddenly became bright and were all frightened. Zhao's mother hurried to the house of the junior teacher to see if something was wrong. Then, she was shocked by the light bulb in the uncle's hand.

"Fourth brother, what is in your hand?" Zhao's mother swallowed and asked.

Uncle Master: "Light bulb."

Zhao’s mother: “We don’t have electricity at home, so why does this light bulb light up?”

The junior teacher laughed: "Because I used potatoes to generate electricity."

"What? Can potatoes generate electricity?" Zhao's mother was so shocked that her eyes were about to pop out, her eyes fixed on the potatoes under the light bulb.

My son asked him for potatoes and it turned out to be a power generation?

These cooked potatoes can generate electricity, which is incredible.

Uncle Master: "Yes, this involves a lot of chemistry knowledge..."

As he spoke, he seemed to be giving lectures to everyone, Zhao's mother quickly stopped him.

Well, they really don’t know chemistry!

Zhao's father and three sons were also shocked. The whole family surrounded the light bulb and looked at it. Zhao's father and others were unwilling to do their jobs.

After this day, every night, the Zhao family will have a bright house.

In one day or two, the villagers have not noticed it yet.

After a long time, people who got up at night were discovered.

Then, everyone in the village learned about the potato power generation.

The villagers ran to Zhao's house to ask about the electricity generation of potatoes. The uncle didn't hide it from him and told everyone who asked him.

Then, the villagers all ran to the city, bought light bulbs, went to the waste recycling station to find metal sheets and wires, and made their own batteries after they came back.

After that, every household used electric lights.

Later, people from other villages also learned that potatoes generated electricity.

People in the city also knew that potatoes generated electricity...

The county leaders reported this matter and then began to promote potato power generation nationwide.

The uncle of the junior teacher was praised by the county leaders for this and rewarded him with a job in the city to the uncle of the junior teacher.

But the uncle of the junior teacher didn’t think about going to the city to work. Isn’t it good to enjoy the happiness leisurely at home? What should I do if I suffer and suffer in the city?

So, the uncle of the junior teacher said very "concertically" that he would give his work to his three brothers. As for the brother who went to work in the city, he would let the three of them draw lots to decide.

The three brothers are so excited!

Go to work in the city! There is still a formal establishment!

I will be a city man from now on!

For rural people, this is an opportunity that everyone envies and wants to have!

Then this opportunity was placed before them.

The three brothers are even more grateful to the junior uncle, and they are their beloved younger brothers!

Zhao's mother also wanted to stop it, thinking that this opportunity belongs to her younger son and cannot be given to others.

The junior uncle quietly said in Zhao's ear: "Mom, it's too hard to be a worker, I don't want to go."

Zhao's mother did not object, but kept telling her three sons that the opportunity was given to them by the younger son. No matter who had received this job quota, the salary for the first two years must be generally handed over to the younger son.

The three sons nodded repeatedly, but even the three daughters-in-law did not object, and they also felt that this was the right way.

The little man in the heart of uncle rolled around with laughter.

What a group of cute and silly people.

They still feel good if they exploit them themselves.

It's simply!
