What were they doing?

"I recently came up with an interesting idea.

"Well, what's it about?"

It's a beetle type flying unit.

What?

Beetle?

Actually, there are not many insects on the continent of Pandor. So the word "beetle" didn't seem to ring a bell with Eira and Katya.

"I see... ...... this is the kind."

Jin drew a picture of what looked like a female canary or beetle on a piece of notepaper.

"Oh, this one. I've seen him before. I've seen it... ......, um, where was it?"

"Eira-san, I think it was on a study trip to the Shoro Kingdom. You remember when you flew into the light of the window at night?

That's it!

Most insects are phototaxis, which means that they move at a certain angle to the light.

Those that move toward the light are called , and those that flee toward the dark are called .

Insects that are attracted to light have <.

In addition, they not only aim at the light but also fly at a certain angle to the light. In this case, they may fly around the sun or the moon, but in the case of street lights, they may fly around them as if they were planets.

Let's stop for a moment.

"So, this is how the beetle flies.

Jin drew a picture of a canary flying with its forewings open and hindwings flapping.

In reality, it is the beetles (both male and female) that fly with their forewings open in a V-shape, while the canarybugs fly with their forewings closed and their hind wings alone.

Anyway, it seems that Jin got what he wanted to say.

"I see, you mean that you want to make an exterior that can be opened to form wings.

Jin nodded.

"Yeah. But I've been doing some research on my part, and it seems that the larger the size, the less suitable this method becomes.

"Yeah?　Why is that?

"That's because... ......"

Jin wondered how to explain this.

This is the field of fluid mechanics. In very simple terms, the larger and heavier the plane is, the less susceptible it is to the influence of air, and the smaller and lighter the plane is, the more susceptible it is to the influence of air.

A small and light model airplane will fly even if thrown by hand, but a large and heavy airplane will not float (i.e., will not fly) unless its speed is increased by a powerful engine.

"You can sort of understand that, can't you?"

"Oh, that's why it's limited to small golems, isn't it?"

Eira understood the explanation, even if vaguely, and Katya understood why Jin had shared this idea with them.

"That's what I meant."

Jin had a way to make the golem fly without this method, but he couldn't talk about it at the moment.

"Yes, it would be smart to store the main wings when not flying!"

When Jin had shown me the wing before, it was folded in a similar way to a folding umbrella.

"Oh, it would be nice to fold up the thin and strong wings and spread them out when they fly."

This is an image of the hind wings.

"Yes, as long as it is strong enough, it would be good.

Jin guessed that a golem about 10 centimeters tall would work.

However, Eira and his team are currently developing a small golem in the 40-centimeter-tall class.

In that case, a combination of smaller wings and a powerful propulsion system would be more suitable.

< for now, Jin and the other three decided to move on to their original topic, the application of the .

"Once again, let me remind you that if you use <> instead of <>, you must choose the right application for it, otherwise it will be very difficult to use or have poor performance.

Eira nodded at Jin's words and continued.

"Yes. That's why they are suitable for <><>.

And Katya also said,

"By making it <3-dimensional>, the range of application has been expanded and it is easier to control, but the original characteristics are still the same.

He summed up the situation as follows.

"Considering these characteristics, what kind of applications are there?

This is the key. is not just a study, but something that can be of use to people.

This is a philosophy that has been handed down since the time of the first Magecraft Meister, Adriana Barbora Zetsi.

"How about <>?"

Katya suggested first. Jin agrees.

"Yes, that's a good idea. It consumes little magic power and basically takes only two states: on and off.

"And the water pumping machine that Katya mentioned earlier. It pumps water, so it requires a little more power, but the fluctuations are small.

Eira agreed with Cachéa's idea.

"That would be nice too. And, as I said before, I think water heaters for bath equipment would be good, too."

"I think ventilators for mines and such would be good, too," he said.

"How about heating equipment for blast furnaces?"

"It could also be used for refrigerators and freezers."

"It's not practical, but you could make a fountain."

"I think it would be good for clocks."

"I think it could be used in washing machines."

How about a home heating system?

How about a doorbell?

"It may not be very strong, but it could be used as a barrier.

"Couldn't it be used for boring?

Various ideas were raised, such as, "Can't we use it for drilling?

recorded all of them in the minutes of the meeting.

"Wow, you've come up with a lot of ideas.

is impressed. But Eira says,

"Well, we all want to try, but it's hardly the role of ," she says, a little disappointed.

Eira looks a little disappointed.

<, laboratories are assigned to each theme, and no one is encouraged to do research that deviates too far from the norm.

It is a necessary rule to maintain order in the organization.

"Hmmm, I wonder if we can do something about that."

It is not a compliment for Jin, who is also one of the founders, to take the initiative in breaking the rules.

Then Reiko gave him some advice.

"Father, can't you do something about this as a temporary research topic?"

"Temporary or ......, I can manage that, can't I?"

<, we will study the development and application of <>.

If it proves to be practical, we may consider establishing a new laboratory as a new research topic.

"Yes, let's do that."

"I'll take care of the procedure!"

Katya is enthusiastic.

Jin was also very enthusiastic, as he had hoped to have a clear idea about this topic.
