Dancing Circles on the Horizon of Events

I heard Waltz's only wish to know what Teresa and the others were making, and moved the place from the dining room together.

At that time, Waltz and I came along with a new maid (?) Eve, and the water dragon and the flying dragon, and Teresa the guide.

It should be noted that Yuki, together with Cortex, went to the Speaker's Office to conduct the proceedings as Boleas' unofficial ambassador.

And the hunter had disappeared into the conference room because of a meeting in the morning.

As for both of us splitting apart with the exception of Cortex with a look that seemed to be glued back to Waltz's body... well, don't you have to bother telling me?

... so.

Waltz, guided as close to the dining room to a not so big warehouse, stepped inside that slightly dim room.

And against Sole, who gradually came to see from the other side of the door, Waltz...

"This is what caused the explosion..."

And with his mouth, he simultaneously gave a frightened expression, a surprised expression, and an expression of interest.

On the other hand, the water dragon, the flying dragon and Eve seemed to tilt their heads or have a difficult look like they were having trouble reacting.

"Mm-hmm. It's a preliminary" OHC "!

"... I have no idea which neighborhood is preliminary..."

Next to a single-cylinder engine the size of its own, waltz with a suspicious gaze at Theresa explaining with a look like a doyah, with her hands on her hips.

"Wasn't a two-cycle engine easier because it had fewer parts scores and didn't even need an oil circulation mechanism or anything?

"No, no, in principle, we couldn't do two cycles."

What do you mean? "

"Valve" of intake and exhaust or "cam" to move it, plus "timing belt" to convey power to the cam and "tensioner" to adjust the sagging of that belt...

If you're comparing a two-cycle engine to an OHC four-cycle engine, you're going to need at least that many extra parts, but apparently Teresa says increasing the number of parts points is not an issue...

"... it's fuel."

"Fuel? Gasoline, light oil, isn't it some flammable liquid around there?

To the smell that filled the room, Waltz threw such an inquiry while somehow anticipating Teresa's response.

Theresa then opens her mouth, shaking her neck to the side.

"... you didn't know where the oil that feeds the fuel was... I don't even know how to refine it (what is octane value?

(Uh... you know what? I was gushing out of the mountains on my way to North Fortress, Teresa, you don't know that...)

With that in mind, at the same time, he wandered around the mountains in search of a burning liquid (petroleum) (?) Waltz that doesn't even remind me of Yuki.

Well, that doesn't matter here, so let's put it aside.

"Which means you're not using oil for fuel, are you?

You're right.

With that said, Teresa glanced toward the royal castle clerk (tech) who was near the engine.

Then, towards the engine intake, the staff begins to hold hands somehow.

Perhaps instead of fueling them, they're doing some magical manipulation.

"... no way... manpower..."

"Manpower... no, it may be true, but when I hear that, it sounds somewhat unpleasant..."

"So... can I just say 'Magic Engine' powered by magic?

"'The Magic Engine'... I wonder if that sounds better than manpower for the rest of it"

and it was time for the two of them to have such an exchange.

Dogowong!!

When you suddenly hear an explosion from the engine and think white smoke has blown out of the exhaust outlet (straight pipe),

Gwwwwwww!!

Magic Guide Engine (?) began to spin in a fierce momentum.

"... I think... the efficiency of magic, magic power-magic energy conversion used by wizards is actually bad without a ton of demos, isn't it?

"No? What's that?

"... yeah, nothing"

A waltz with an unconvincing look at the fact that officials who should only be able to use very common magic started turning engines that were supposed to be very impetuous and not so mechanically efficient.

Immediately thereafter,

Dogowong!!

... because I turned the engine too vigorously, or there was a hole in the top (head) of the engine... and some fragrant calf engine oil erupted...

"Ah, the head's blown up again."

"Are you using food oil for engine oil?

"Hmm? If I could lubricate it, would that be good? Besides, this is a test."

"No, that's right, but..."

... Again, waltz with an unconvincing look on his face.

For the record, if you don't use it for a long time, it is possible to substitute engine oil even with salad oil.

Some engine oils, etc. are made from whiskey oil (sesame oil) as raw materials, so, well, is it obvious?

But Teresa's prototyped engine was apparently a simple air-cooled engine of the type that cooled with air, and on top of that, the sudden turning of the engine literally burned the internal parts...

Perhaps the carbide food oil stuck around the lower specific heat valve and stopped closing, pushed by the piston for each valve and drilled a hole in the head...

Waltz asked Teresa after anticipating, 'The reason the engine broke down is around there,' etc.

"So, let's get back to it, wouldn't a two-cycle engine have been better if it'd been enough to cause such a malfunction? I don't have a valve..."

"No? Structurally difficult. The magic you're using instead of fuel is combined magic with fire magic and water magic, but when you try to use it on a two-cycle engine, the spark doesn't inhale properly, and it explodes where it's not a cylinder."

"Water vapor explosion... that's technically different..."

"Mm-hmm. But maybe it's close to that. This prototype engine has two intakes, a spark created by fire magic from one side, and compressed water created by water magic from the other. And when the water heated by the insulation compression and fire magic spark caused by the piston to rise changes to gases, it causes the same gas expansion phenomenon that caused the fuel to explode. As a result, the piston can be pushed down to extract mechanical energy."

... long, so to sum up, I mean, it's exploding water instead of fuel.

Incidentally, even gasoline engines in the modern world have long existed that aim to improve output by spraying water inside the engine.

"That's the thing... That it's an ecological engine for a long time..."

In order not to use gasoline, a clean reciprocal engine, in which the combustion chamber does not become extremely hot and produces little nitrogen oxide or carbon dioxide...

As for the complaint, would it be the same as an electric vehicle with a hydrogen fuel cell?

Besides, fuel is... magic.

Except for the fact that water comes out as waste, it could be described as exactly a zero-emission agency...

"Still, ladies, you've learned a lot about making something like this, haven't you? I think you had to learn thermodynamics and stuff, but you're gonna need basic math and physics knowledge to do that, right?

"It's..."

Theresa shuts her mouth, looking like she's going to have a hard time talking to me somewhere after I say that.

But after it was slightly, she nodded and opened her mouth.

"Cole made me a textbook and I taught you!

(Cortex... You've had a similar hobby with me so far...)

and Waltz, who himself reminds Catalina that he is giving individual classes.

I mean, Cortex would have done the same thing to Teresa.

"Yes... So... you're saying you're gonna have this engine on your own plane?

In such a waltz inquiry, Teresa shook her head sideways again.

"No, not yet. On the ground and above, if the pressure is different, the temperature is different. I don't think we can fly safely without creating a stable engine that works in such a completely different environment. Plus, there's not enough output at all, so we have to think about multi-cylinder and high-rotation, and durability..."

"Hey... think that far..."

"So now, as a plan B, we're just testing the gas turbine engine for magic. However, the production accuracy of the bearings and the durability and heat resistance of the oil seal are difficult, so it cannot be rotated so high... Still, the craftsmen are working hard to make it, so we'll just have to wait and have a long neck."

Waltz finally loses his word to Teresa who talks to him.

... Still, she succeeded in putting into her mouth the biggest question that was in her.

"... how the hell can you do so much?

Move people, learn knowledge, repeat trial and error...

For Waltz, who has done so far only within his peers and who has managed to do most of the difficult things by himself, he couldn't understand the reason for Teresa's motivation to work with strangers to do all sorts of things in parallel.

Theresa, who was asked such a question, answered with a full grin, looking straight at the waltz with her hands on her hips.

"From everyone's dreams. It is the concubine's concubine who will make it happen!

"... yes"

If there are many other people with the same goal, can they run like Teresa...

To Waltz's eyes, her appearance, answering with joy, seemed just a little dazzling.

Before such a slightly blue waltz, Teresa is unexpected to her (?) Start saying things.

"That's because we all admire waltz, isn't it?

"... Huh?

"... who made the energy? Who put such a big door to the field on the surface? And who thinks they've remodeled the royal castle and town and revitalized Mid-Eden's economy? It's all waltz, isn't it? You don't think the Kings and the people don't realize that?

"Then I guess Waltz can get more chest strained. Waltz is never alone."

"... you're in trouble."

"Everybody loves things."

Listen to Teresa like that, and, uh, waltz reminds me of someone who said the same thing recently.

And at the turn, waltz also smiled bitterly (...) and (...) smiling when he saw a dog beastly girl with an impressive yellow natural perm smiling as she turned her nee and white teeth to herself.

"Not at all... The balance of this world... what are you going to do?

"Isn't that good? If we all want to do what we want and perish together. At least not for a concubine..."

"If that happens... I'm a real demon."

And Waltz felt like he had caught another glimpse of one end of what he called a demon god, and he sighed small.

... Thus the distance between Waltz and the royal castle staff and the king's people gradually approached.

Beyond that is fulfillment ruin or prosperity...

No matter how much I tried to imagine, happiness or unhappiness, I couldn't seem to have predicted it for Waltz.
