So I didn't expect that as soon as I invented this steam water lifter, everyone immediately thought of its main use, including more and more extensive uses, and got their unanimous praise and amazement, fortunately I couldn't help but be a little surprised, it seems that the wisdom of the ancients is really not to be underestimated.

Therefore, fortunately, I don't dare to be proud, and I am humble.

"Eh, everyone has won the prize, this is actually just a small invention, just to let everyone see the magic of steam again, open our minds, we can really use it to do many things, such as sailing, such as pumping, such as weaving, and so on."

"In short, don't be limited, you must open your mind as much as possible, diverge your thinking, dare to think and dare to do, in a word, only you can't think of it, you can't do it without it."

And hearing Wan Xing say this, Wan Chengdao is also excited.

"That's true, son, I really didn't expect that this steam engine would be so useful, it's incredible!"

"Anyway, how did you do this, what is the principle, can you explain it to the father in detail?"

"Also, what is the vacuum and atmospheric pressure you just mentioned, why has my father never heard of it before?"

Hearing this, I heard my father keep asking questions to myself like a curious baby, eager to know what was going on, and in desperation, I had to explain patiently.

"Dad, how to say it, this problem is a bit complicated in detail, not so easy to understand, not easy to explain, simply put, in the air we live in, there is not nothing, but there is pressure, although you can't see or touch, but it really exists, I call it atmospheric pressure."

"Atmospheric pressure?"

"That's right, Dad, it's atmospheric pressure, you can also understand it as a force, and it's a pretty strong force, but we don't usually feel it, because the pressure inside and outside our bodies is balanced, so we cancel each other out."

"But if we take the atmospheric pressure of one side of the equation, then this equilibrium will be broken in an instant, and the strong atmospheric pressure will immediately squeeze and flatten the other side."

"For example, the reason why boiler No. 2 can pump water is because it was filled with steam at the beginning, so the atmospheric pressure inside and outside it is balanced, and there is nothing surprising about it."

"But when I poured cold water on it, the steam inside it instantly condensed into water and formed a vacuum, so the atmospheric pressure dropped dramatically."

"At this time, the well connected to it, because the atmospheric pressure is obviously stronger than it, forcibly squeezes the well water into it until the boiler is filled with well water, so that the atmospheric pressure on both sides reaches a kind of equilibrium again."

"In short, you can understand that the strong atmospheric pressure will keep squeezing the weaker side until they reach some equilibrium, understand?"

Shaking his head in confusion, Wan Chengdao even reached out and touched it in the air, which was very incomprehensible.

"I don't understand, son, what are you talking about? Why can't my father understand it at all, what atmospheric pressure is what vacuum, there is obviously nothing in the air, my father didn't feel the pressure you said, isn't he really lying to me? ”

Seeing this, fortunately there is also a little helplessness, because it is indeed a little difficult to popularize the science of atmospheric pressure vacuum or something for the people of this era, just like listening to the book of heaven, after all, they have never been exposed to this knowledge, and they can't understand it at all.

My father is okay, but he just doubted it, and he didn't believe it completely, and ridiculed himself.

Otherwise, if you come to another person, I'm afraid you really feel like you're crazy, in nonsense, in this good air, how can there be any atmospheric pressure, I can't feel it at all, it's not nonsense?

Therefore, in desperation, he couldn't help but think that it seemed that the Magdeburg hemisphere experiment or something should be put on the agenda as soon as possible, but he couldn't be hasty, he had to find a time to pretend to be a big force, so that more people could see it and completely open up the wisdom of the people.

Only in this way, through clearly visible experiments, can they really believe in their fathers and realize that there is indeed atmospheric pressure, otherwise, they will not understand this kind of empty vernacular explanation at all.

Therefore, fortunately, it is not difficult for the strongman, and the province is looking for trouble for himself, after all, what is the use of forcing his father to understand the atmospheric pressure now, he has the current scientific experiments, and he can't use it at all, so let's study the steam engine with peace of mind first, and the province is stunned.

So he shook his head with a smile and said in a deep voice.

"Okay Dad, this question is indeed a bit troublesome, it's not so easy to explain, or I'll do an experiment for you when I have a chance in the future, so that you can feel it for yourself."

"Let's not talk about it for now, let's leave it for now, and continue to return to our previous question, how about it, you have figured out the method of taking water from steam, right?"

Hearing this, Wan Chengdao also nodded again and again and said with a smile.

"Hehe, son, I understand this, after all, I have seen you demonstrate it with my own eyes, it is indeed quite magical, it is because my father has underestimated it, I thought that this steam can only be used as power on the ship to propel the ship to sail, but I didn't expect it to be used to get water, it's really a little incredible."

"Of course, I said, Dad, the magic of this steam is definitely more than that, so then you should study and study it, and strive to invent the steam engine as soon as possible, and innovate my steam water lifter, so that it is more convenient and convenient, so that it can be promoted, okay?"

"No problem, son, I can't ask for it for my father, such an interesting thing is worth studying carefully, after all, this is something that can really benefit all people, and it is more meaningful than a rocket for my father."

Saying that, after thinking about it, Wan Chengdao is Tao again.

"By the way, is there any other use for this steam engine? You might as well tell me about it, so that my father can ponder it more carefully, and find out, so that my father can think about it day and night. ”

I heard my father say this, thought about it, and felt that it was too, so I would mention it a little more, so that my father could be one step ahead in the research and development of steam engines.

After all, at this extremely important and critical moment, there may be some unexpected use and help for them.

So fortunately, I also said with a smile.

"Okay Dad, then I'll tell you again, it's still the same sentence, as long as you study this steam engine, it will definitely be infinitely useful, and it can be used in all aspects of our lives, and it can be called a great artifact."

"For example, as I told you back then, this steam power can not only be used to propel a ship to sail, but we can also use it on the wheels to propel the car forward."

"In this way, there is no need to rely solely on manpower and animal power, it is faster and more convenient, and even as long as the fuel is sufficient, you can run tirelessly, travel thousands of miles a day, gallop like the wind, and then even if it is the distance to the ends of the world, it can also be reached quickly, connecting all parts of my Daming, and truly benefiting all people."

"Acting on the wheels to propel the car forward?"

Immediately, hearing Wan Xing say this, with a look of anticipation, Wan Chengdao was a little puzzled again.

"Son, no, how does this steam power work on the wheels? To tell you the truth, it's not that I haven't thought about this problem before, but I just think it's unlikely. ”

"After all, if you think about it, although this steam power is powerful, it is also unstable, but it is a volt together."

"Like you said, it's a constant up and down of the lid of the pot, not a continuous and constant power in the same direction, so it can't act on the wheels at all, isn't it a run pushing the car forward and backward? What's the use of that, it's equivalent to going around in circles, just doing useless work. ”

smiled, seeing that his father had keenly discovered the key to the problem, fortunately he also smiled.

"Hehe, Dad, you did find the crux of the problem, steam power does have this problem, but as long as we solve it, won't we?"

"Solution, how to solve it?" Wan Chengdao was even more puzzled, and he couldn't figure out how to solve it.

After all, although this steam power is strong, it is indeed a volt together, and it is constantly churning up and down with the lid of the pot, is it difficult to let it only go up and not down? How is that possible!

After thinking about it, I saw my father's puzzled face, and fortunately he said directly.

"In this way, Dad, you come with me, and I will take you to see one more thing, and then I believe you will understand."

Saying that, fortunately, he didn't talk nonsense, and directly pulled his father into the backyard kitchen, and the mill used to grind tofu at home pointed to the stone mill in the house.

"Dad, let me ask you, what is this?"

Seeing that Wan Xing actually pointed to a stone mill at home and asked himself what this was, Wan Chengdao was also confused, not knowing what he wanted to do, he really thought he was a fool, and he didn't even know the ordinary stone mill?

However, he also knew that Wan Xing would definitely not dare to joke with him at this time, so he replied honestly.

"Son, isn't this just a stone mill, what's the problem?"

Fortunately, he glanced at him with a smile and continued to say with a smile.

"That's right, Dad, it's a stone mill, let me ask you again, how is this stone mill used?"

Wan Chengdao was even more puzzled, scratching his head and looking at him puzzled.

"Just push and pull, no, son, what do you want to say, why is the father more confused the more he listens?"

I saw that Wan Xing snapped his fingers and praised appreciatively.

"That's right, that's right, Dad, this stone mill is to push and pull to do the work, as long as we keep pushing and grinding, we can grind beans, think about it, just like you just said, the steam power is not stable, but a volt together, constantly tossing up and down against the lid of the pot."

"And if we imagine the undulation of the steam against the lid of the pot as the push and pull when the grinding disc is used, and the undulation is equal to the push and pull, then can this undulating power be converted into a stable and continuous power through this primitive method?"

"And if you think of a grinding disc that rotates under this power as a wheel, then ......"

Immediately, without saying the next sentence, I saw that Wan Chengdao himself was extremely surprised and excited.

"Then you can really put this undulating power on the wheels and push the car all the way forward!"

As he spoke, he saw that he was in ecstasy, and all his doubts were solved at this moment, and he was ecstatic.

"I understand, son, the father finally understands, you are such a genius, the father finally knows how to apply this undulating power to the wheels, I understand, I understand everything, haha, hahaha......"

Wan Chengdao, who was extremely excited and extremely happy for a while, did not delay for a moment at all, and ran to try it without looking back, to invent the steam engine, to act on the wheels of this magical steam power, and to invent the kind of magic that Wan Xing said, you can run tirelessly by yourself, without the need for manpower and animal power to travel thousands of miles a day!
