Daming: The system rejected my request for salted fish

Chapter 148

They really don't have a concrete concept, and it ultimately comes down to a problem of cognition.

Wei Wu also understood this, so when everyone was silent, he gave them a specific concept.

"You've all boiled water before, right? When the kettle boils, does the hot steam lift the lid?"

The craftsmen looked at Wei Wu, not knowing why he mentioned this, but nodded in unison.

"The steam engine I'm talking about is based on a similar principle, which uses steam to convert it into power."

"But sir, the lid of a pot has so little power that you can just hold it down with your hand. How can it be used to propel a large ship?"

As soon as Wei Wu finished speaking, Song Zhong asked another question, and then Wei Wu also gave an answer.

"Then have you noticed that when you hold up the lid, a lot of hot water will come out from the spout?"

"Because the steam has an outlet, you think it has no power and can be easily suppressed."

"If you don't believe me, you can ask Sun Chang to make you a kettle without a spout and then seal the lid tightly."

"You can try boiling water then, but I advise you to stay away from it. Be careful not to be killed by the exploding kettle."

After hearing what Wei Wu said, the craftsmen all lowered their heads and began to think.

At this time, they seemed to have some idea of ​​what hot steam was, but not much.

Just as they were deep in thought, Wei Wu spoke again.

"I have a lot to teach you, but everything starts with a foundation."

"Next, you will learn from me and use what you have learned to help me build the steam engine."

"Remember, this will be the greatest opportunity of your life, a precious chance to make your name known in history as a craftsman."

After saying this, without waiting for the craftsmen to react, Wei Wu began to fiddle with the mobile phone and projector on the table.

When the projector image appeared on the wall, the craftsmen were shocked again.

When they saw the walkie-talkie before, they could still talk and marvel at it.

But when they saw the scene before them, they couldn't even speak because they were all scared.

After a long while, someone finally came to his senses and pointed at the wall with a trembling hand.

"My Lord, my Lord, this, this thing... is immortal, why, why is it, I..."

Seeing that the man was stumbling and unable to utter a complete sentence, Wei Wu simply waved his hand to interrupt him.

"Okay, it's not a magical weapon. Remember, we are the Royal Institute of Science and Technology. Everything here is a product of technology."

“Maybe you don’t understand now or in the future, but as long as you are willing to learn from me and have an inquiring mindset, I will be able to help you.”

"I believe that as long as you work hard, one day you will understand it, and even create something that others cannot understand."

After hearing what Wei Wu said, the craftsmen not only did not calm down, but became excited instead.

It is no exaggeration to say that the scene happening before our eyes is a miracle.

But Changlebo told them that this was created by human hands, and was willing to teach them. How could they not be excited!

Fortunately, despite their excitement, the craftsmen did not disrupt Wei Wu's class. Instead, they looked at him with anticipation.

Just when everyone was full of anticipation, Wei Wu stretched out his finger and lightly swiped the screen of his mobile phone.

The next second, a structural diagram of a reciprocating steam engine was projected onto the wall.

(Illustration in the author's words)

At first the craftsmen were shocked by the projected image, but they soon shifted their attention.

All eyes were focused on the structural diagram.

The most concerned among them are carpenters, because their craftsmanship is most directly related to the structure.

Afterwards, with Wei Wu's explanation reading from the book, the craftsmen understood how the steam engine works.

Wei Wu then switched to the next picture and explained them one by one to the craftsmen.

Throttle valves, centrifugal governors, steam boilers, safety valves, pressure gauges, etc.

These things may sound complicated, but they are not simple at all.

At least it was not easy for Wei Wu. Many things are easy to say, but you will know how difficult they are when you try them yourself.

Modern people all know that glass can be made using quartz sand, but how many people can actually make it at home?

This principle is the same as the steam engine today.

Fortunately, Wei Wu only needed to say it, and the remaining production issues were left to the craftsmen.

This time, three firearms craftsmen were excluded from the craftsmen selected from the Ministry of Works.

The remaining number of blacksmiths was six, carpenters was seven, bricklayers was four, and other types of craftsmen totaled six.

After thinking for a while, Wei Wu made a decision.

Originally, he was a little worried about whether he could find the materials to make the steam engine.

After learning more about it later, I was completely relieved that the wisdom of the ancients was no worse than that of later generations.

The method of making coke has existed as early as the Song Dynasty, and blast furnaces even appeared earlier than coke.

The Ming Dynasty basically used blast furnaces to smelt iron, but the blast furnaces at that time were still relatively simple.

"Sun Chang, there are six of you blacksmiths in total and you are the leader of the blacksmith group."

"What you need to do next is to make these accessories on the drawing with precision."

"The cylinder block and base are made of cast iron, the crankshaft and connecting rod are made of wrought iron or mild steel, and the sealing piston rings are made of copper."

After saying this, Wei Wu looked at Song Zhong again.

"Song Zhong, the seven of you are the carpenter team. You will be the team leader. Your main responsibility is to thoroughly study the blueprints and work with Sun Chang to create the accessories."

"Also, while you're studying the blueprints, I want you to build a waterwheel by the river. We'll build our own blast furnace in the future."

Finally, Wei Wu looked at the four bricklayers, a stonemason and a sculptor.

"You six are the construction team. Building the blast furnace is up to you. Here are the blueprints. Take a look!"

As he spoke, Wei Wu swiped the screen of his mobile phone with one hand, and a standard and complete drawing appeared on the wall.
