Early Ming Dynasty: Turning Clouds and Rains into New Learning Saints

Chapter 42 Because I have no brains
The Crown Princess was still visiting, and Zhu Jingjing couldn't help but be surprised and said: "This really uses the river to help with work. How is this done? No, no, no, how did you come up with this?"

Although it is said that China has had waterwheels and the like since ancient times.However, those are just ways to guide water from rivers to farmland.Zhang Yifan's use is very novel.

It was also the case that Zhu Jingjing exclaimed, what he saw was completely different from the water wheel!

As for how to do this, you can see it with your eyes, so she changed the direction of surprise.

Hearing her exclamation, the Crown Princess also turned her attention.

From outside the cement workshop, one cannot see the full picture of this hydraulic facility.But at this time, the Crown Princess, Zhu Jingjing and the others could see the whole picture.

After looking at it, the Crown Princess couldn't help but sigh: "What a wonderful idea, it turns out it can be like this!"

If you want to talk about workmanship, it is definitely not difficult.How could I have thought of doing this and let the river do the work?

When Zhang Yifan heard their sighs, he actually curled his lips inwardly. I showed you the good things, but you couldn't understand the mystery at all.

The part of his hydraulic facility that is exposed outside the river is actually called a pelton turbine. In its original history, it was invented by Pelton in modern times.

The efficiency of this type of water bucket turbine in utilizing water power has reached an astonishing level, with the energy conversion of water reaching as much as 90%.However, there is actually no technical difficulty, it is just unexpected.Therefore, this thing can be invented thousands of years in advance. It can even be said that as long as a waterwheel can be built, it can be invented.

The principle is actually very simple. At the beginning, the water flow hits the wooden board to cause rotation, and then the wooden board is changed into a wooden cup shape, and then this is the next step, which is to let the water flow hit the middle part of the two wooden cups, that is to say, it can turn The energy rebounded after the impact of the water flow is also utilized.

For those who don’t know this trick, the same waterwheel uses completely different energy.

At this time, Zhang Yifan is just using it to replace labor. When the time comes in the future, the same device can be used to generate electricity.In fact, later generations of hydropower used this type of water bucket turbine to generate electricity.

Then, there is also a mechanical energy conversion device, which is actually very rare, which is the crank connecting rod device.

However, what Zhang Yifan used was just the opposite. The hydraulic impact of the turbine rotates, and then it is converted into piston motion to rotate the hammer.If this were turned upside down, it would be the device inside cars and steam trains.

These mysteries were placed in front of the ancients, but no one understood them.

At this time, Zhang Yifan had no intention of revealing these secrets. He just answered Zhu Jingjing's question calmly: "As long as you use your brain more, you will naturally think of it!"

"Why didn't I think of that!" Zhu Jingjing said with emotion after hearing this.

When a masked man who was working not far away heard this, he raised his head and said, "Because you have no brains!"

This man was Erniu, a strong man, so he was taken to the cement workshop to do manual labor.

As soon as he said these words, the Niu Daddy next to him was frightened. He immediately slapped Er Niu on the back and made him jump forward. If it hadn't been for the mask, he would have been beaten. Take a bite of cement.Niu Daddy didn't care about him at all, but quickly apologized: "He is talking nonsense, miss, please don't take it to heart!"

Of course Zhu Jingjing was not happy being called brainless.But seeing this scene and Zhang Yifan by her side, she couldn't have a seizure, so she had no choice but to forget it.

But who would have thought that Erniu got up and muttered: "Why are you beating me? That's what Brother Fan said about me! It's so simple that you can't think of it. He just has no brains. He also said that he would give me his brain..."

Niu's father didn't expect that he would give birth to such a stupid son, so he became anxious, so he used his hands and feet together, punching and kicking, and beat Er Niu down again.

Zhang Yifan saw it and ignored it.

If Erniu speaks for himself, he has to bear the consequences of his words.After being taught a lesson by his father, he will probably have to go through his brain a bit when speaking in the future.Otherwise, if you don't have a long memory, who knows what trouble will happen.

However, Zhu Jingjing couldn't stand it anymore and said quickly: "Don't fight, what Brother Fan said must make sense!"

"..." The Crown Princess was speechless after hearing this.

Hey, I'm an outgoing girl. If I really marry this country boy in the future, I'm afraid I'll have to help count the money after being sold, right?
But fortunately, she has a great father!

While she was thinking about it, Zhu Jingjing had already asked Zhang Yifan with a smile: "Why are you so smart? How did you do it?"

Zhang Yifan did not dare to tell her a clever joke, but answered her: "In fact, it is simple, it is observation, summary and reasoning. This science can be called wuxiology or logic."

There has always been a point of view that in Chinese history, most of the people were academically inclined, that is, partial to philosophy; while science, on the other hand, requires more logic.China lacked this, so in the development of history, science was eventually surpassed by Europeans.

Although Zhu Jingjing heard the name Gewuxue better, Zhang Yifan ended up talking about logic. She immediately asked without thinking: "What is this logic like? Can you teach it?" Me?"

The princess next to her was speechless. She felt that she was a bit redundant, and she couldn't get anything to say as Zhu Jingjing rushed to speak.

Oh, by the way, didn’t I want to know the cost of cement? Why was Zhu Jingjing leading me astray?If you don't speak anymore, what kind of logic will you be talking about?

Although the Crown Princess is indeed interested in this logic, she still remembers the cement thing after all.

Therefore, before Zhang Yifan could answer, she hurriedly interrupted, interrupting Zhu Jingjing's question and said: "Let's put this logic aside first, let's verify the cost of cement first!"

When Zhu Jingjing heard this, she immediately came to her senses. Feeling a little embarrassed about her eagerness, she did not express any objection.

After all, the cement matter was an important factor in the sister-in-law's decision to take charge of her marriage.She herself also wanted to know, what is the cost of such easy-to-use cement?
After hearing this, Zhang Yifan pointed to the workshop in front of him and explained to the princess: "The cost of this cement is first the cost of fuel, and the second is the labor cost before and after firing. These two items account for the majority. At present, Estimatedly…”
