Chapter 544 New Source of Power

Yearning for a new world... Roland laughed dumbly. ??

Then he asked Nightingale to summon Anna.

At this time, the former will always avoid it automatically and give the two of them space to be alone.

Anna was wearing a light blue short dress today, with knee-high black stockings visible under the skirt, and a pair of moccasin boots, which made her look full of energy. These modern-style clothes were made by Roland under the guidance of tailors in his spare time. The fabrics are made of liquid coating provided by Soraya. They are not only light to wear, but also very durable, which is very suitable for her to use when processing equipment.

When he saw her watery eyes, Roland could not help but smile.

Of course, now he no longer needs to be as honest as before.

Roland pulled Anna onto his lap and sat down, smelling her fragrance from behind. After a while of intimacy, Roland got to the point, "I want to develop a new source of power."

"Like a steam engine?" She turned her head, and along her white neck, her protruding collarbone could be seen.

Roland couldn't help but stretched out his hand and touched it, causing the latter to burst into low laughter.

"Your Majesty, let's get down to business."

"Ahem, okay," he put Anna down and pulled out a stack of design drawings from the manuscript on the table, "Take a look at this first... How much can you understand?"

"Hmm..." As soon as she enters the learning state, Anna's expression will be completely immersed. Just looking at her selfless look, Roland will feel an inexplicable shame - as if he is sitting under the bright window. In the classroom, he peeked at his deskmate who was writing furiously.

In order to balance this mentality, he decided to make Anna beg for mercy that night.

"I probably understand." Anna flipped through the last drawing and nodded after thinking for a moment. "It is also driven by steam, but the pushing piston is replaced by a windmill blade, thus eliminating the need for reciprocating movement of the connecting rod. , am I right?"

"Absolutely correct," Roland put away his reverie and replied with a serious face, "Its name is a steam turbine, which essentially still uses high-pressure steam to propel it, but its efficiency is much higher than that of a reciprocating steam engine. "

This is the revolutionary product that Roland has been imagining for a long time.

It can be said that the original intention of freeing basic industries from the restrictions of witches is also based on this original intention - in this way, Anna can concentrate on higher-end mechanical production.

The steam turbine was his foray into this field.

Steam turbines are extremely versatile. They can be used as both ship power and thermal power, especially the latter. It is foreseeable that after Dragon Dragon Ridge is recaptured, Count Speer will have to stay in her town for a long time. When dealing with government affairs, it is difficult to maintain the night lighting in the factory area with Miyue's magic power alone, let alone the electrification project in the residential area. Of course, Roland was unwilling to admit that this was a planning failure caused by his lack of experience. If he wanted to make up for this mistake, he could only use conventional means to make calls.

Due to the inherent flaws in the cycle principle of the steam engine, the current coming out is sometimes high and sometimes low, and circuit voltage stabilization is Roland's weak point, so it is a more appropriate choice to use a steam turbine with more stable output power and higher thermal efficiency.

"What should I do first?" Anna asked.

"Like the last gunboat," Roland turned to a page with blades painted on it, "create a functioning verification model. It doesn't need to be too big, just about one meter. It mainly solves the angle problem of the blades and can make high-pressure steam Smoothly pass through each static blade grille. As long as you do this step, you will be more than half successful."

Without detailed data, how can we create a usable finished product like this?

Just trial and error.

Regarding the impeller part, which is the core of the steam turbine, Roland is not worried about the processing difficulties at all. Black Fire's cutting accuracy is far better than that of later finishing machine tools; he also does not have to worry about material strength. After all, the working temperature of the impeller is between five and six hundred degrees. The alloy steel Lucia found was strong enough to handle the task. The key lies in the angle matching between the static blade cascade and the moving impeller. The former is like a fixed fence, adjusting the angle at which the steam passes to prevent it from swarming into the impeller, causing direction confusion or even opposite forces. In essence, it is the same. Use a comb to detangle the airflow.

If the model can function normally, there will be no difficulty in scaling it up and manufacturing it.

When the level of processing methods and materials improves, it is inevitable to produce fruitful industrial results.

"I understand," Anna's eyes sparkled with excitement.

"Don't worry," Roland held her hand. "You should have heard from Wendy that I decided to take the initiative to capture the devil."

"Well," Anna blinked, "will you follow me this time?"

Roland shook his head slowly.

"That's okay." She leaned her head on his shoulder. "The last time I saw you injured, it almost scared me to death."

"Really? But I heard Nightingale say that you are the calmest one on the scene. If you hadn't dealt with it decisively, I might have really -"

Halfway through, his mouth was covered by Anna's soft hands, "Don't say that word casually."

"I understand." After Roland nodded, she released her palm. "Anyway, what I want to say is that you must protect yourself, understand? If an accident occurs, use the God's Punishment Symbol immediately. Don't hesitate. Even if the devil is not caught...I will wait for your triumphant return at the castle."

"Don't worry," Anna smiled, "I won't let them hurt other witches."

…

After she left, Roland was silent for a long time before saying in a deep voice, "Are you there?"

"Of course," Nightingale's figure appeared on the desk, "But I didn't eavesdrop on what you said. I only came back after seeing her leave."

He stood up and walked to the window, looking in the direction of the snow-capped mountains, and roughly described the hunting plan in his mind, "Before going out, you have to rehearse several times in advance to familiarize yourself with the entire capture steps and the tasks you are responsible for each other. . But this is only a plan for chasing a small number of devils. The specific method must be adjusted according to the actual situation." Here he paused, "If the arrest operation encounters the worst situation... ...I mean the irreparable kind, you have to bring Anna back no matter what."

Nightingale did not answer immediately. It was not until Roland turned to look at her that she said with a complicated expression, "Is this the real reason why you don't go?"

Roland did not deny it, "Otherwise you would definitely choose to save me, right?"

"...I understand," she sighed softly, "I will do my best."

"Apart from her, you are the only one I can trust," Roland patted her on the shoulder and said word by word. 8
