I saw the kettle on top of the charcoal fire, the water inside was boiling, but the most important thing is, where is the lid? Where is the lid?
It’s amazing that you can understand the steam engine without the lid!
Zhang Mingwei was really speechless, so he asked: "Didn't you notice that there were no lids on the pots when you were observing?"
His question immediately made a group of people dumbfounded.
They were smart and immediately realized that a lid was needed to observe this!
Huang Zongxi couldn't help but feel annoyed when he thought about this, and subconsciously explained: "With the lid on the pot, you can't see the water boiling."
The others all nodded after hearing this.
"..." Zhang Mingwei was speechless again after hearing this. Maybe they even specially asked someone to remove the lid of the pot.
So, without saying anything, he asked someone to put a lid on the pot, and then had someone plug the spout.
Later, Zhang Mingwei said to them: "Okay, you guys will pay attention next."
Hearing this, both Zhu Yuluo and Fang Yizhi all stared at the kettle to see what would happen.
At this moment, Zhou Yuji, who heard the news, also ran over.
He also secretly boiled water about the truth that could change the times, but he didn't find anything, so he was very curious.
In just a moment, the boiling water vapor pushed the lid up, released the steam, and then fell down again, and so on.
After watching for a while, Fang Yizhi found that there was no other phenomenon. He couldn't help but feel a little puzzled and said, "It doesn't mean that boiling water can lift the lid of the pot, right?"
"Yes, that's it!" Zhang Mingwei replied affirmatively after hearing this.
Fang Yizhi also said it casually, but he didn't expect it to be true. Suddenly, he felt a little stupid. What kind of truth is this that changes the times?
He did not respect Zhang Mingwei as much as Huang Zongxi, so after hearing this, he said a little unhappy: "Could it be that the Duke is entertaining us?"
The princess was here, and he didn't dare to talk nonsense. If the princess were not here, she might have said something even worse.
At this time, Huang Zongxi was also a little disappointed. According to his thinking, if Zhang Mingwei could one day come up with so many incredible conclusions about his folding fan falling to the ground, then this era-changing conclusion would definitely be very shocking. The result is just boiling water and opening the lid of the kettle. What does that count?
However, he and Fang Yizhi had different ideas. They didn't think Zhang Mingwei would amuse them, so they said to Zhang Mingwei sincerely: "Please let me know clearly!"
He believed that there must be truth in it.
On the contrary, it was Zhu Aona, because she had watched documentaries and seen steam trains. She kept staring at the lid of the pot, which was lifted and lifted, and steam came out one after another. At this time, she finally thought of something, and asked a little uncertainly: "Sir, is it possible that the strength of this pot lid can pull something, such as a car?"
When Zhang Mingwei heard this, he pointed at her and praised: "By the way, this is it. You are really good at thinking of this!"
In ancient times, it was important for a gentleman to stay away from the kitchen. It can be said that these people around here are all in this category. Before Zhang Mingwei asked them to observe, they probably had never seen boiling water.
In addition, even if you see it occasionally, if you are not sensitive to the conversion of power, you will not think of using the power of steam.
If one had to find one Ming Dynasty who might realize this truth, it would probably be the one Zhang Mingwei asked the emperor to summon before.
At this time, neither Fang Yizhi, who was living a good life, nor Huang Zongxi, who was living a decent life, thought of this. After hearing that the princess's words were correct, they were all surprised.
"My lord, how can this steam power pull a cart?" Huang Zongxi couldn't figure it out, so he asked directly.
Fang Yizhi also asked: "So what if I can pull a car? How does this change the times? At most, it's just a car!"
They really couldn't figure it out and felt that Zhang Mingwei was exaggerating.
However, Zhu Yuyao was affirmed and knew that her association was right. Of course she knew that it would definitely change the times. The car that sprays air can be very long and can transport a lot of things.
At this time, seeing them questioning Zhang Mingwei, he became a little angry and immediately said to them: "I am stupid and don't know how to ask for advice humbly. Is this how you seek education?"
"..." Upon hearing this, Fang Yizhi and Huang Zongxi did not dare to refute the princess's words, at least their attitudes changed on the surface.
Zhang Mingwei could see that although they changed their attitude after being told by Zhu Yuyao, in fact, they must be dissatisfied in their hearts.
Well, even the Commander-in-Chief next to me doesn’t agree!
Zhang Mingwei glanced at Zhou Yuji and then said to them: "Have any of you seen the waterwheels in the fields?"
Huang Zongxi has seen it, but Fang Yizhi and Zhu Auao have not. Zhou Yuji ignored him if he didn't speak.
Zhang Mingwei then explained to them: "The water falls and drives the water wheel to rotate, so that the water wheel automatically fills the people with water. This is an application of power transformation. This steam is actually the same."
Without waiting for them to ask questions, he continued: "However, the power of water cannot affect most people due to terrain restrictions. However, the power of steam can be used anywhere, as long as it can burn Water can produce steam, thereby utilizing the power of steam."
Having said this, Zhang Mingwei pointed at the kettle and said, "Each of you can try the power of this steam. Press the lid and feel it. Be careful not to get burned!"
After hearing him explain the truth with examples, even Fang Yizhi, who was the most unconvinced, already knew that there must be some knowledge in this, and his attitude improved significantly. After hearing what Zhang Mingwei said and waiting for Princess Kunxing to try it out first, he couldn't wait to experience it too.
"How about it? Isn't this a bit powerful?" Zhang Mingwei said after seeing them all try it, "If this kettle is replaced with a solid cylinder and the lid is replaced with a piston..."
The few people in front of me can be regarded as one of the least pedantic scholars in the Ming Dynasty. What is even more rare is that they do not discriminate against miscellaneous studies and are even studying miscellaneous studies. In this way, there is no better audience than them. Therefore, Zhang Mingwei explained the principles of steam engines to them in detail.
After he had finished speaking, he began to imagine for them: "As the princess said, if this set of things is moved onto a cart and used to replace the ox-drawn cart. As long as this power is not wasted as much as possible, Can you imagine how many carriages it can pull? Also, when it moves along a fixed track, will it be able to move around the clock? Furthermore, if this set of things is moved to a ship, it can be used as a driving force. What? Wait, imagine for yourselves, will this set of things eventually change the world?"
