I became a witch, but I started the industrial revolution

Chapter 29 Steam Turbine, the Prelude to the Age of Giant Ships

However, in this case, Media will have to set up a super department, the National Tax Department.

Because this direct-controlled department with ultimate management authority cannot be influenced and must operate independently, otherwise there would be no point in creating it.

In order to ensure its independence, it must have its own independent prisons, courts and even violent law enforcement agencies within its system.

That is, the power of investigation, judicial power, and law enforcement power, to ensure that no other department has the ability to hinder it.

In addition, local governments must unconditionally cooperate with its work. Add in the fact that auditing and accounting are also under the jurisdiction of the State Administration of Taxation, and the size of this guy is extremely terrifying.

Now this department can be directly governed by Medea himself. If used well, it will be the sword of Damocles hanging forever over the heads of all officials and businessmen who have disloyal intentions and are corrupt.

This can also provide the lower-class people with a fairer business and working environment. Medea allows some people to be rich, but this wealth must be based on her rules.

You can make money, but you can't be the only one making money.

In addition to supporting handicraftsmen in switching to business, the huge financial income gained from the expansion of trade in recent years also allows her to conduct adult re-education classes.

She aims to open adult learning classes in all places within her sphere of influence within the next five years, cultivate sufficient talent reserves and lay a solid foundation for building schools in the future.

At present, she has money, but she does not have enough manpower to provide free education for children, and there are not enough teachers, so she can only build schools flexibly according to the number of graduating teachers.

Of course, there is also a lot of good news. Sendegas is a port city with an excellent deep-water port terminal. What does this mean?

A large steamship, a giant steel warship!

In today's world, all ships, whether military or civilian, regardless of size, have wooden hulls, but they are enchanted wooden hulls.

Wood is actually not that bad. It is relatively light. The ductility, tensile strength and rigidity of some tree species are no worse than iron. Their comprehensive capabilities are even better than iron. Plus, wood is very easy to obtain.

But Medea did not intend to make this thing. First of all, she could not buy wood enough to build warships. No country would be stupid enough to sell this thing.

Even if you sell it, the price is like slaughtering a pig. Even if you bite the bullet and buy it, basically the whole continent knows that you want to build a warship...

Therefore, it is logical and reasonable for her to skip this era and overtake others.

But she can't just overtake. She has three problems to solve.

One is that the steam engine did not have enough power.

The second is how to make naval guns. The naval gun system is also a very complex project.

The third is the training of naval soldiers. Medea can only let the army go into the water~

The problem with the first steam engine was not that Media's steam engine was inefficient, but that she had already developed it into a triple-expansion steam engine with three pistons and cylinders.

Traditional steam engines have already maximized steam utilization. Even the most advanced four-stage steam engine can only utilize steam capacity to close to 40%.

So the development has basically come to an end.

Medea ran to the steam engine workshop and transferred a group of people to follow her to the steam machine tool factory.

Under her command, the lathe worker used the best materials currently available to process a batch of blades and fixed wheels for her.

After she assembled it, a device shaped like a windmill and filled with blades that could rotate appeared in her hands.

Someone asked doubtfully: "Commander, what is this?"

Medea picked up an iron rod, poked it at the fixed wheel, held it in the air and let go. With a wave of his hand, a strong airflow rushed towards it. Under the pressure, its blades began to rotate, and at the same time, the iron rod below was also moved.

"What do you think? If we put aside other devices and find a way to make high-pressure steam blow directly on this set of blades to rotate, and drive the transmission shaft below through its rotation, and enlarge this combination and add more sets of blades, won't the power of the transmission shaft be higher?"

Many people were enlightened and followed Medea's ideas.

"Yes! In fact, we don't need any connecting rod to drive the flywheel. We can just plug the flywheel with resistance plates and let it be driven by steam, right?"

"This does seem to be feasible. Theoretically, if you want to increase the power, you just need to add a set of larger blades, which requires a high level of strength for the casing and blades."

"I think the material used to make the combustion chamber shell of the steam locomotive can be modified and used. The working environments of both parties are very similar."

Medea looked with satisfaction at the craftsmen gathered around her to discuss the plan. In fact, what she was talking about was the prototype of the steam turbine. She couldn't do everything by herself, so she should train them.

Subsequently, under the intentional or unintentional guidance of Medea, the first generation of high-pressure steam turbine was initially finalized.

Simply put, the working principle is roughly equivalent to the wind blowing the windmill to drive the windmill to rotate.

When implemented in a steam turbine, high-pressure steam passes through a narrow channel and increases its flow rate, hitting the fan blades, driving the blades to rotate and generate power.

In order to utilize the steam pressure layer by layer, the fan blades are divided into a fixed stator that cannot rotate and a rotating rotor. The shape of the rotor blades is like a √ with an arc.

The stator blades are used to adjust and change the direction of the steam airflow, allowing the incoming steam to blow the concave and convex parts of the rotor blades at a suitable angle to create a driving force that drives it to rotate.

The overall design is that the stator and rotor are stacked layer by layer, and the fan blades are shaped like a trumpet from small to large, allowing the incoming steam to enter layer by layer and make full use of most of the heat in the steam.

This design has an advantage, that is, the larger it is, the more economical it is and the more powerful it is. The overall device will not take up too much space because it is placed horizontally.

Now that the biggest problem currently faced has been solved, the former shipyard at the Sendegas port has come in handy.

After demolishing the previous small slipway, Media expanded the shipyard's area tenfold with a single stroke of the pen, and the steam turbine experiment and iron ship construction were carried out simultaneously.

Her first step was not to build warships, but steel ships. Warships were too expensive and could easily cause panic in other countries. Most importantly, she needed test products for technical verification.

Building medium to large cargo ships can expand the territory's trade to other countries along the waterways, and large-scale shipments can further lower the cost of goods, which fits in with her plan to develop the economy over the next five years.

If necessary, she could even sell a batch of ships to other countries to monopolize their shipping. Large-scale ship manufacturing could also help her accumulate a group of mature shipbuilding workers.

Warships can be used to conduct sea trials of some models for technical verification. The design and installation experiments of naval guns, etc. all require hull platforms, and can also be used to train naval officers.

She was eager to make dumplings, but there were also basic rules to follow when making dumplings.

Chapter 30 Dimensionality Reduction Strike

Bernaglie

A village at the foot of a mountain

There were bursts of shouting coming from the courtyard of a common wooden house. When I got closer, I saw an old man and a young man pulling the saw blade frantically around a tree trunk that was as thick as a man's embrace.

The long saw slowly cut inwards as the two men pulled and pulled hard. They worked for more than half an hour before they stopped to rest.

The young man was breathing heavily, his sore arms were shaking as he picked up the water cup, a symptom of exhaustion. He took two more breaths before successfully bringing the water cup to his mouth and taking two big gulps.

The old man who was also drinking water looked at this scene and shook his head and sighed: "Alas, if you can't even do this little job, how can you take over my job in the future?"

The young man looked miserable when he heard this: "Dad, this tree trunk is too thick. My arms are so sore from pulling the saw blade. I will have to saw it several more times later..."

After drinking the water, the old man replied slowly: "How can you not work hard? If you don't work hard, why should you earn this money?"

"Once we have finished this set of furniture for Master Amaike, we will have enough money to find you a wife. If you don't have this skill, can you do it?"

Speaking of this, the old man also felt a little disappointed. Carpentry is a technical job and the money is good, which is much better than those who farm for noble lords. But this kid still complains about this and that.

"Have you rested enough? If you have, get up and continue working! If you don't saw well today, you won't be able to finish anything and the deadline will be missed."

Just as the old man was urging the young man to continue working, many neighbors walked past the door, as if something was attracting them.

The young man was somewhat curious and called out to one of the familiar people across the yard: "Hey! Watt, what are you doing?"

"Master Newman is hiring! He said it's for work in the carpentry workshop, and the pay is pretty good! I won't talk to you anymore, I have to go and see if I can be selected."

"What? Woodworking workshop?! Dad!"

The young man quickly turned around to look at his old man. At this time, the old man no longer cared about the work in his hands, pushed open the door and followed him.

The word "carpentry workshop" is related to the work they are doing now. How can they not go to investigate the enemy? Seeing the old man's actions, the young man hurriedly followed.

Soon the two followed the crowd to the gathering point and watched the excitement.

There was a small platform at the edge of the village, where someone was loudly shouting out recruitment requirements and wages. It was clearly stated that they were recruiting people to work in the carpentry workshop.

The old man snorted coldly when he heard this: "You don't want experienced people, you just want young people? Is carpentry work so easy? This is a technical job!"

The old man was still attracted by the people on the stage, but the young man noticed something unusual. Not only were there people gathering on this side, but they were also gathering on the other side, looking at something.

Out of curiosity, he followed the crowd and squeezed to the front, where he could see clearly what everyone was looking at.

It turned out that this was the woodworking workshop that was hiring workers. At this moment, there was also someone loudly selling the wooden stools and tables next to him.

If Medea were here, she would also shout "Wow!"

Using the recruitment benefits to fool a bunch of people who are just watching the fun to sell goods, the person who can come up with this idea is really wasted in this world~

However, the other party had already finished speaking at this time, and the young man had not had time to hear the specific price. His eyes involuntarily looked at the workers who were working in the workshop.

There used to be a bunch of people transporting things back and forth in this house. I didn't expect it was a carpentry workshop.

"With so many employees still hiring, their furniture prices must be higher than ours, so we don't have to be afraid."

The old man also squeezed next to the young man and said, his tone full of certainty.

After all, only two people in their family can do the work, and there are so many people in the woodworking workshop who have to be paid, so the cost must be the lowest in their workshop, and the price must be cheaper than the other party, so there is nothing to worry about.

Just as the old man finished saying this, a sharp sound suddenly came from the woodworking workshop. He looked closely and his eyes almost popped out on the spot.

Two young men lifted a log from the ground and placed it on the iron table.

They didn't do anything, but the high-speed rotating iron sheet in the middle of the iron table pierced deeply into the logs with a sharp whistle and flying wood chips.

As the two men pushed forward, the log was directly sawed in half by the iron sheet.

One of them rotated one of the logs that had been cut in half, adjusted the position and pushed it forward again to allow the iron sheet to cut it. After several rounds of rotation, the original log became a regular wooden board.

The whole audience was in an uproar, and the old man and the young man who were mixed in the crowd stared at it all with eyes wide open in disbelief.

Thinking back to the piece of log at home that had made them almost die from sawing, and seeing how relaxed the other person was, the young man could not help but turn around and look at the old man with suspicion.

"...The furniture they make is so crude! Look at the ones outside, they are so ugly and square."

The old man responded to his son's gaze with some lack of confidence, changed the subject and continued to watch what the other party would do next.

The more he looked, the colder the old man felt, because he discovered that there were more than one of these strange machines in this woodworking workshop, and their functions were different.

Some are for cutting, some are for drilling, some are for friction... Different machines do different things. Several workers are responsible for one step and produce a large number of identical wooden parts.

Finally, with the cooperation of a group of people, these parts were assembled into seat benches, stacked together and prepared for the final shade drying and painting.

They watched as a corner of the yard was slowly filled with furniture made by this group of workers. It was a number that the two of them could not produce in a month.

Just at this moment, the hawker on the stage next to him came up again to sell his goods and talked about the price. After hearing the specific price, the old man's legs suddenly went weak and he leaned on his son beside him.

Because the price the other party sold these wooden furniture was twenty times lower than theirs!

"Dad? Dad! Ouch, everyone, please help, my dad has fainted!"
