Chapter 402 Solar cooker display, people from the Municipal Light Industry Bureau came
After Minister Lu learned that Duan Hongxuan was an old friend, he was so excited that he couldn't wait to see the new product invented by Duan Hongxuan, so he pulled Duan Hongxuan to the steel rolling mill first.
When Director Yang saw it, he trotted a few steps to lead the way, and the rest of the people followed closely behind. Everyone wanted to see the invention of this talented boy!
Director Yang led everyone to the fitter workshop. Along the way, Minister Lu kept pulling Duan Hongxuan to ask about his life and study. His care and love for Duan Hongxuan was beyond words, which moved Duan Hongxuan deeply.
It also made everyone watching around jealous and envious. Everyone couldn't help but make their own little calculations in their hearts, thinking about how to have a good relationship with Duan Hongxuan and see if they could get on Minister Lu's line!
Even if you can't get along with Minister Lu, there is no harm in getting closer to Duan Hongxuan. Anyone with a discerning eye can see that, even though Duan Hongxuan is young, he is very capable, so it goes without saying that he will have a bright future.
If we can have a good relationship with him now, it will be beneficial and harmless no matter what!
Along the way, everyone had their own thoughts. Soon, everyone came to the open space at the door of the fitter workshop, and saw something like a disaster standing in the open space, except that the cauldron was held by a shelf and lifted off the ground.
It's about half a meter high, and there's a shiny glass mirror inside, and there's a large bracket above it, which seems to be used to store something.
When everyone saw such a cauldron-like thing, their curiosity aroused and they started talking about it.
Factory Director Yang quickly stepped forward and introduced without waiting for Minister Lu and others to ask questions: "Comrades, let me introduce this cauldron to you!"
"Haha!"
"Hahaha!"
"...!"
As soon as Director Yang opened his mouth, everyone immediately burst into snickers!
Director Yang paused for a moment before continuing: "We call this big pot a solar cooker.
From the name, you may have understood to some extent that this is a stove, and it is a stove that uses solar energy!"
When Director Yang introduced it, everyone found it interesting, "This solar cooker uses a magnifying glass to focus the sunlight. However, the magnifying glass transmits the sunlight, while our solar cooker reflects the sunlight. All the
The sunlight reflected by the trans panel is focused on a single point, and the huge heat it generates is used as a stove!
Having said so much, why not give you a live demonstration so that everyone can see with your own eyes that we use this solar cooker to boil a pot of hot water!"
After finishing speaking, he asked the staff next to him to bring up a large aluminum kettle containing about five kilograms of water, and then placed the large aluminum kettle on the bracket of the solar cooker!
Factory Director Yang saw the staff putting away the aluminum pots, raised his hand and looked at his watch, and then continued to introduce to everyone: "Now that we have entered autumn, the sunshine is worse than in summer.
We just did an experiment a few days ago, and the time it took to boil this pot of water was about twenty minutes!
The most suitable season for using this solar cooker is summer. According to our inventor, classmate Duan Hongxuan, this solar cooker can theoretically boil five kilograms of cold water in no more than ten minutes in summer!
In our northern region, especially the northwest, there is drought, little rain, and long sunshine hours. Solar cookers are more suitable for these areas!
Everyone has seen the benefits of using a solar cooker. You don’t need to burn coal, let alone firewood. With such a solar cooker, you can use it as long as the weather is not cold and the sunshine conditions are good!”
After Director Yang’s introduction, everyone immediately thought of the benefits of this solar cooker and became interested!
Minister Lu asked Duan Hongxuan curiously: "Hongxuan, this little genius of yours really deserves your reputation!
This solar cooker is great! It saves coal and can be used as long as the sun shines. It’s great!
How did you come up with the idea of inventing the solar cooker?"
Duan Hongxuan replied sheepishly: "The invention of the solar cooker is actually a product that came to us unintentionally!"
"Oh?" Now not only Minister Lu was curious, but everyone else was also curious. At this time, Director Yang opened his mouth to save Duan Hongxuan and said: "Hahaha! Let me tell you!
Just like Duan Hongxuan said, he really came up with this solar stove accidentally!
Hongxuan designed a new machine tool for our steel rolling mill. Last Saturday I went to Hongxuan’s home to get the drawings of the new machine tool. At that time, we were sitting in their small courtyard drinking tea and chatting, and then I accidentally discovered this small courtyard.
There are two large black iron buckets placed on the roof of the two wing rooms.
I was curious and asked him, what is this iron bucket used for?
As a result, Hongxuan told me that he likes to be clean. He would practice boxing and kicking in the yard when he had nothing to do. In the summer, he would be covered in sweat after even a little activity.
If you have to take a shower after sweating, use cold water. He knows Chinese medicine. Even in summer, taking a cold shower after exercise is not good for the body.
But if you want to take a hot bath, you have to heat the hot water, which is troublesome!
After thinking about it, he came up with a lazy way to paint the outside of the iron bucket with black paint so that it can absorb the heat of the sun well, then put it on the roof, fill it with water, and wait for a few hours.
, the water released is hot, even a little scalding!
Now the problem of taking a bath is solved. There is no need to boil hot water. You can always have hot water whenever you want to wash!
I was immediately interested!
Hongxuan saw that I was interested in this, and then told me that the sun can actually be used to boil water.
He told me about some children playing with using a magnifying glass to focus sunlight to burn ants, and then he came up with the idea of focusing the reflected sunlight to a point and using the high temperature it generates to boil water!
That’s how solar cookers came to be!”
"Hahahaha! Wonderful, really wonderful!" After listening to Director Yang's introduction, Minister Lu immediately put his hands on his hands and laughed: "I didn't expect that this solar cooker turned out to be an accidental acquisition!
Hongxuan, you are very good!
It’s amazing to be able to combine children’s fun things in life with science and technology to create practical products that ordinary people can use!
This chapter is not over yet, please click on the next page to continue reading!
Comrades, we talk about inventions and creations all day long, but our scientific and technological workers cannot just work behind closed doors, they must look more, think more, and open up their ideas!
The emergence of solar cookers is a good example!"
Everyone around him was also filled with admiration. No one expected that the solar stove came like this. They were greatly impressed by Duan Hongxuan’s flexible mind and profound knowledge!
At this time, Vice President Gao became interested in what Director Yang said about Duan Hongxuan’s black iron bucket, and curiously asked Duan Hongxuan: “Classmate Duan Hongxuan, your black iron bucket allows you to easily have hot water for bathing in summer.
Don’t you think about extending it to thousands of households?”
"Vice Principal Gao, this simple solar water heater is only useful in summer, but not in other seasons!
And its technical content is too low. It is just a large iron bucket filled with water, painted with black paint on the outside so that it can better absorb the heat of the sun. Basically, anyone with good hands-on skills can make it by themselves!
Therefore, for such promotion, it may not be good for any factory to produce it. It is best for each street to promote it!
Moreover, there are limitations to the use of solar water heaters. Like our courtyard houses in Beijing, few homes have bathrooms, and many families don’t even have a decent kitchen at home. In this case, even with this water heater, there is basically no need for it.
Great use!
But for residents who have a bathroom, this water heater is quite practical!"
After listening to Duan Hongxuan's words, Vice President Gao thought for a while and nodded: "That's true. If there is a factory to produce it, just sell it. If there is no bathroom at home, it is not practical to buy it back!
If you have a bathroom at home, you can find a big iron bucket and make it yourself! From this point of view, this product is indeed not easy to sell!
I didn’t expect that you, who is engaged in invention research, would actually care about the market. It’s not simple!
In my opinion, with your ability and your vision for products and the market, you can become the director of a smaller factory!"
After hearing Vice President Gao's words, everyone looked at Duan Hongxuan with envy and admiration! He is a serious man with real abilities. Even without Minister Lu, Duan Hongxuan's future achievements would not be the same.
Not going anywhere!
Everyone was chatting and laughing, and the topics discussed were inseparable from the solar cooker and Duan Hongxuan!
While everyone was discussing the solar stove and Duan Hongxuan animatedly, Director Yao suddenly appeared with two people.
As soon as he arrived, he quickly ran to Minister Lu: "Old leader!"
"Oh? Why is it you? I remember you were the director of the thermos bottle factory, right? Why did you come to the steel rolling mill during working hours?"
"Hey! Old leader, I'm here to do something serious!
Let me introduce to you, old leader, this is Director Liang of the Municipal Light Industry Bureau, and this is Director Wang of the Light Industry Bureau!
Director Liang, Director Wang, this is my old leader, Minister Lu from the Ministry of Machinery Industry, and this is Vice Minister Xie!"
When Director Liang and Director Wang heard that one was a minister and the other was a deputy minister, they immediately stretched out their hands with a little panic and said hello respectfully: "Hello, Minister Lu, hello Vice Minister Xie!"
Minister Lu and Vice Minister Xie reached out and shook hands with them. Minister Lu asked curiously: "So he is a comrade from the Light Industry Bureau!
I wonder why you came to the steel rolling mill today...?"
Director Liang quickly replied: "Director Lu, Director Yao invited us here. He said he had some kind of solar cooker. Let us take a look!"
"Solar stove?" Minister Lu couldn't help but look at Factory Director Yao and said: "You Yao Tietou, when everyone heard your nickname Yao Tietou, they all thought you were a straight-up fool!
I know you are more thoughtful than anyone else!
What? Are you thinking about Xiao Yang’s solar cooker?"
Upon hearing this, Director Yao quickly explained: "Old boss, I made an agreement with Director Yang this time, and I only came with his permission!"
"Oh? Xiao Yang, is what Yao Tietou said true? You won't be tricked by this guy again, will you?"
