Magicraft Meister Part 3

Jin explained the details of the <> to the members of the <>.

"...... In other words, you can make magic tools without using Magi Stones or Magi Crystals. But only for limited purposes."

Reinhardt was the first to speak.

"So, it has the disadvantage of low output and not being good at rapid changes in output, but it also has the advantage of being able to make magic tools at a low cost?

"That's the way it is."

"It's use is limited, but it can be applied to a variety of consumer products. Street lamps, heating, and so on.

Bina said. <, was no exaggeration.

"Yes, that's right. It can be used for light fixtures including night lamps.

It consumes little magic, and once it is turned on, it can be left on until the light gets brighter.

Heating is similar. The only difference from lights is that the cycle of <, turning off when it gets hot and turning on when it gets cold, is a little shorter.

"Couldn't we use it for a water pump?"

Lewis says.

"It doesn't seem that difficult if you only need to pump a certain amount of water.

To which Reinhardt replied.

"Yes, Lewis is right. But the output is so small that I think it will only produce a little bit of power unless we can find some way to drive it in parallel.

"I see. But if that's the case, it won't be difficult to put it to practical use, will it?"

"Well, it's not that difficult. At a glance, it seems that if we put five sets in parallel, the performance will be better than that of ordinary magic tools.

Jin agrees with Reinhardt's estimate.

"I think it is about that much. The cost of using magic circle is ...... hmmm, compared to using magic crystals (magi crystals), it's about half to a quarter of the cost of using five of them in parallel."

"I thought it would be a little cheaper, but it's not, is it?"

Bina began to explain to Lewis.

"You're right, it is. It's fine for the lights, but in the case of the pump, the mechanical parts account for more than half of the cost."

"That's true, too. I understand."

This explanation made sense to Lewis.

"In the end, what is the operational efficiency of the free magical element (ether)?　Is that why it is low?

Hannah asked.

"Something like that.

Jin replies.

"What is the problem with that?　The magic circle itself?　Or the medium?"

"Eh ...... umm ......"

The question from Hannah made Jin stumped.

"I know that using regular paper would reduce the cost. Then, what if we use a more expensive material, such as ...... yes, leather of a magical beast?"

Which is greater, the increase in efficiency or the increase in cost, Hannah said.

"We can't compare the prices in Hourai Island. ...... old man, do you understand?"

At this point Jin decided to ask the old man.

<

About 10,000 to 100,000 yen.

Of course, dragon-type materials are excluded since they are not distributed.

"More than 100 times the cost of paper or ...... the cost outweighs the effect."

The cheapest way to construct a 3D magic circle was by <>.

Paper is suitable for this in terms of thickness, but it has poor magical properties.

On the other hand, if they used leather from magical beasts, the performance would not improve with the increased cost.

"Kuhuh, that's where the magi system comes in.

Saki speaks up at this point.

When Jin was in , he had heard about this technology from the old man and had been secretly researching the materials.

"When I experimented with paper made from trees from Horai Island, instead of ordinary paper, and stored in the free ether box for a week, the efficiency increased by about one percent," he said.

"How does that break down?"

"It's due to the better conduction to the magic power."

One percent per week. That would be 50 percent for a year, I don't know," Saki concluded.

"However, the problem with this is that the paper must be from Horai Island to be effective.

This means that the paper in general circulation is not good enough. Jin was disappointed.

"There is one more thing I tried, Jin."

Saki continued to cheer Jin up.

"What's that?"

"It's to impregnate ordinary paper with a paint that has good magical properties.

"I see. <?

That's right, Jin. That's right!

According to Saki's experiments, impregnating paper on the market with magi-polyethylene improves the magic power transmission by 50 to 70 percent.

"Hmmm, still a minus in terms of cost, right?"

Reinhard said.

"In the first place, Magi Polyethylene itself can only be made here.

Saki responded to Reinhardt's words with a wry smile.

"That's right, Reinhardt.

"Well, isn't there a better way after all?"

Jin was about to lose his strength, but then he said, "No, no, no,

"No, no, no, Jin, please hear me out.

Saki said, "No, no, no, no, Jin, please hear me out.

"There is one more magi material that is commonly available."

"What?　........................ Oh, right, the magic resin!"

"That's right. I'm sure you're right Jin.

Saki praised Jin with all her might.

"The magic resin can't be made thin by itself, but if you impregnate it with paper, it's another thing.

"Indeed.

In modern Japan, there are substrates for electronic circuits called "paper phenol substrates.

"So, this improves the magic power conduction by 40 to 60 percent," he said. But it costs twice as much."

"That's subtle."

"But it was cheap to begin with, so it's practical enough for the unit price."

If it's used where miniaturization is needed, the performance is better than with just paper, and the cost is low enough.

"That's for sure."

Jin agreed.

"Kuhu, if paper made from wood from Horai Island is impregnated with magic resin also from Horai Island, and then aged with <>, we can expect about three times increase in efficiency.

"But that's still not enough."

I'd like to hear one more," Jin said.

"I'll try a little harder on that side."

Saki accepted the offer and said, "Leave it to me.

Then Goose spoke up.

"Jin, Saki, I just thought of something, how about mica?

"Mica. ......"

Mica, also called mica, has a thin, peeling crystalline structure.

Since it does not break easily, Jin once put white mica on the windows of the village of Kaina instead of glass.

"Yes, yes, yes, good, good, goose!"

Saki was overjoyed to have a new research subject.

"Jin, I'll check it out!"

"Yes, please!"

Saki's reassuring words put Jin's mind at ease and he entrusted the project to Saki.
