Under Han Tuozhou's involvement, the Duke's headquarters irreversibly used steam power to build a boiler room like a fortress. Like a cement crock crusher, the steam power here is not a piston steam engine, but a steam turbine.

The first practical one in history was of course the piston steam engine. However, some verified parties pointed out that the earliest steam engine was successfully trial-made in Beijing by the famous Jesuit Nan Huairen in 1672. There was a most primitive boiler installed in the center of the car body. Well, you can also think it is a coal stove plus a bent neck kettle. The steam power produced by Nan Huairen is not complicated. The coal fire boils the water in the kettle until it boils and vaporizes it, and then sprays steam outwards. The steam flow blows to the wooden impeller. The wooden impeller turns, and then drives the wheels of the wooden cart to rotate, and the cart starts to move quickly.

Why is steam turbines later than piston steam engines put into practical use? In fact, it is just because the steam turbine speed of the steam turbine is relatively high. In the era without gear reducers, how to control the speed is simply a huge problem. Relatively speaking, the speed control of the piston steam engine is relatively simple.

Mao Geng has now solved the problem of gear reducers. Anyway, he has initially had the ability to produce gear reducers, so he chose to go to the steam turbine first.

Since cement production started with steam turbines, production capacity has been greatly improved, and some people are encouraged by this.

But after Zhao Yan came to Kaohsiung, he moved into the Duke's headquarters and was immediately attracted by the various novel patterns in the headquarters. Tap water, squat ceramic toilet flushing system, waterfalls, fountains, including transparent pain frame windows and spring sofas, etc., Zhao Yan looked here and touched there, and was very excited. Zhao Yan was smart since childhood and had a much better ability to accept. After he had thought about something new, he could understand the truth. Soon, the new things in the headquarters could not satisfy his curiosity.

In Taiwan, the indigenous people do not need Zhao Han to issue orders for the time being, and the gold mine in Taipei is still smooth, and the gold is produced more and more, but there is no need for Zhao Han to worry about. Taipei's city cannot be built in a short while. As a result, Zhao Han has not had many things to worry about. Zhao Han is idle, and after the freshness of living in the first two days of the first two days of living in the throne, he is no longer satisfied with staying in the throne. Instead, he has an unstoppable interest in everything Mao Geng did in Kaohsiung. It is impossible not to mention that Zhao Han is a young man with pursuit:

"Mao Geng, look, you not only have male disciples, but also female disciples to preach and solve their doubts. I am idle and idle, how about learning from you?"

Looking at the young emperor in front of him, he looked very studious, and thought that he might be the future emperor. He was on a whim and was infinitely curious about science. This should be a good thing, at least it would always be beneficial to the development of science in the future of the Song Dynasty.

Zhao Han had already seen the boiler in the gear. In the gear, Zhao Han wanted to look at this and that, but no one dared to stop him. However, the boiler was one size smaller than the boiler on the cement side. When Zhao Han looked at it, the operator first released some pressure to ensure that there would be no accidents when the Duke arrived. But after seeing this small boiler, Zhao Han said that he would also have to look at that big guy.

Mao Geng had no choice but to make some arrangements for this, and he also partly relieved pressure. When Zhao Han arrived, he hurriedly looked around and left by Han Tuozhou and Mao Geng.

"I haven't seen clearly yet. Mao Geng, how did that crocodile crusher act? The power is so powerful!"

Zhao Han wanted to turn back and continue to see clearly. Mao Geng quickly coaxed the emperor's grandson with kind words:

"Duke, I have asked someone to make a model of an alligator crusher in the past two days. No! It is a model of an alligator crusher that includes steam-powered. When the Duke looks at the model, he will understand."

Han Tuozhou also said:

"Duke, that's just a mechanism to smash stones. If the Duke is interested, why not go and see how to burn glass? It's amazing to burn glass."

Zhao Yan knew that everyone was worried about something, so it was not easy to use force. Moreover, Mao Geng agreed to make a model for him, so he took the lead and went to the donkey:

"Okay! It's okay not to look at the alligator crusher, or the boiler here, but if you want to see something else, you can't stop me anymore."

Mao Geng nodded repeatedly and agreed. Mao Geng thought to himself: My little ancestor, as long as you don’t insist on staying next to this first-generation boiler with a poor safety factor, you can do whatever else you want.

In order to divert Zhao Yan's interest, Mao Geng had to take Zhao Yan to see the fired glass.

When you come to the workshop where glass is burning, you can feel a heat coming from afar. When you enter the workshop, it is even more hot. The operators here are sweating, and some of them simply go barefoot to fight because it is too hot.

Zhao Han endured the heat and came to the crucible furnace. The furnace for making glass was below the ground, a furnace dug down and then made of refractory bricks. Four crucibles were arranged symmetrically above the furnace, and white flames spewed out of the crucible, and inside it was the melted glass solution.

The operator put a scoop into the crucible, scoop a scoop of glass solution, pour it into two iron rollers, and the iron roller rotates and turns into a soft red plate-like object. Don’t think that as long as it cools down, it will be a flat glass. No! You have to anneale while it is hot. So far, continuous annealing cannot be achieved, so the efficiency is very low.

However, for Zhao Han, it was already an eye-opening. A pile of sand and stones were placed in a crucible and burned, and then it could be burned into glass water, then rolled into flat plates, and after annealing for dozens of minutes, it would be a transparent flat glass. There were also many auxiliary processes, such as polishing, cutting off irregular parts, and finally turning into square and standard-sized transparent glass.

So that's how glass comes from!

Of course, it seems simple. In fact, if you don’t know the formula, you can’t make glass at all. If you know the formula, you don’t have a crucible that can withstand high temperatures, you can only stare at me. Zhao Yan was just watching the fun, but in fact, there was no way to see what was inside. Mao Geng didn’t plan to explain the chemical and physical processes in it to Zhao Yan. Mao Geng felt that Zhao Yan didn’t need to know these, and Zhao Yan was tactful and did not find the bottom line.

Today's glass workshops not only produce flat glass, but also make various utensils, cups and plates. Curious baby Zhao Han carefully watched the process of casting various utensils, cups and plates. When he saw the magical blowing glass technology, his eyes were straightened.

Zhao Han seemed to be listening to a heavenly book. After listening, his eyes were filled with stars and a look of admiration on his face. It took him a long time to say:
Chapter completed!
