A mana stand.

This is a concept that Jin had been working on for a long time.
However, it was difficult to find an opportunity.
In modern Japan, you can imagine a charging facility for electric cars or a hydrogen station for hydrogen cars.

As long as there is no or low demand, the diffusion rate will be slow.
Jin thought that the mana station would be more meaningful if more and more households have the opportunity to use mana.
Mana is made from free magic element (ether). And free magic element (ether) is supplied from the sun, Seran.

There is no danger of depletion under normal consumption. We can rely on the free magical element (ether) with peace of mind.
If we choose to rely on fossil fuels, as on the earth, we should be worried about the environmental pollution of Ars.
The aether converter is a little, or rather a lot, bigger than the aether converter, and is a mana supplier. Because of its low efficiency, it takes a long time to charge ...... mana.

Jin's idea was to make it smaller and more efficient, to attach something like a meter, and to sell mana for a fee.
This would create a new occupation, <
"......Hmmm, sounds interesting."

Erza nodded with an interested look on her face.
"I've been thinking about talking to Reinhard about it.
Jin thought he could get some good advice from the most politically minded member of the Jin family.

"So, first, I'll make a mana stand, and at the same time, I'll approach the Kingdom of Selroa and the Shoro Kingdom."
The old man, who had been listening to Jin's conversation, gave him a hint. Jin nodded.

"I will do so.
He wanted to contact the kingdoms of Elias, Klein, Egelea, Franz, and Mitsuho if possible.
Jin started to discuss with the old man, Reiko, Elsa, Taishaku, and others to decide on a general policy first.

"We will make the first one for each country, and leave the rest to the magecraftsmen of each country, shall we?

When filling mana for a fee, we want to make sure that the amount of mana is proportional to the price, but if we leave it to each country, there is a possibility that they will cheat.
However, I don't think it would be the same if we made all the mana ourselves.
"Brother Jin, how about we decide how much it costs by the time it takes to fill it?"

Erza said, "Then there shouldn't be a big difference by anyone's standards.
"Well, it might be harder to cheat than a meter, but you could intentionally slow down the supply time. ......"
If they wanted to cheat, they could.

"It would be nice if we could fill up a mana tank of this size and say how much it costs."
It is difficult to do so because the mana tank is not standardized.
"Is it hard to expect good intentions ......?

Yes, it is. It is rather impossible not to consider countermeasures against bad intentions.
"...... Do you think it's unlikely that you'll come to a conclusion soon?"

"Yeah, that's probably true.
Erza also looked a little tired.
"Brother Jin, why don't you make a

"Yes. ......"
Whenever I get stuck in a thought, I sometimes have a good idea while I'm doing something else.
Jin decided that developing a pressure cooker was necessary and would not be a waste of time.

"Okay. Then, while I, Erza, and Reiko will make a new pressure cooker, will you and Taishaku keep working on the mana tank?"
Yes, sir.

Thus, Jin, Elsa and Reiko moved from Jin's workshop to Elsa's workshop. Edgar was waiting for them there.
"Miss Erza, Miss Jin, we have been waiting for you.
Edgar said that he had received a call from the old man.

Jin did not want to act as if he owned the place in Elsa's workshop, so he thanked the old man inwardly for his concern.
"......Brother Jin, it's a pressure cooker, but if it's not sealed with a lid,......warding?"
"Oh. I think it should be a weak wind attribute warding."

The internal pressure of a typical pressure cooker is about 2 atmospheres, or 2.5 atmospheres at the highest.
The ones used in Horaijima have more than 3 atmospheres and even 10 atmospheres, but they can be used safely because adamantite is used for the pot and hexenbiest leather is used for the gasket.
"...... and, then, the flow of magic control (magi sequence) is like this, correct?"

On a whiteboard made of ground spider resin (GSP) for examination, Erza writes a flow of magic control (Magi sequence) mixed with Magi Formula.
"Ah, it looks good. Elsa, you've grown up."
"Thank you for ......."

Erza's cheeks turned red as Jin praised her.
"Well, well."
Jin wanted to say something to the blushing Erza, but he couldn't think of anything clever to say at the moment,

"Let's decide what material the pot itself should be made of.
He could not come up with any clever words at once, so he could only say something regrettable like, "Let's decide what material the pot itself should be made of.
"If we are going to apply pressure by means of a boundary, can we use an ordinary metal?

"Yes, I think so.
"If that's the case, then ......"
Brass is the most common material used by ordinary people for pots and pans. However, brass is surprisingly, or rather,

However, Jin could not judge whether it has a bad influence on cooking or not.
The stainless steel used in the modern earth has less than 1/20th of the thermal conductivity of copper. And yet, it is used for pots and kettles.
"Hmmm ......"

The price of copper is 1800-2700 tol per kilo, iron is 5000-7000 tol per kilo. 5,000-7,000 Tall per kilo.
This is because of the high production of natural copper, but leaving that aside, Jin wanted to make a pot out of stainless steel this time.
This is because copper-based pots quickly oxidize and turn black. It takes time to polish them.

Therefore, some common people said that they could tell whether their wives were good or bad by looking at the pots and pans.
Not necessarily because of this, but because the people favored cookware made of stainless steel, which is resistant to acids and alkalis and rust-resistant, even if it is a little expensive.
"I guess the way to reduce costs is to increase the production volume," he said.

That is not something that can be done overnight.
"Father, isn't it a good idea to start out a little expensive?
"Well, I guess so."

If that is the case, it could be one of the trade goods. Since nickel and chromium are less expensive than in modern earth because they are not commonly used, there is a good chance that the price of stainless steel will be lowered.
"There is a lot of work to be done, but it is worthwhile as a person whose vocation is to make things."

The only thing that remains is the combination with the warding.
The pot is made of 18-8 stainless steel, and a magi crystal is attached to the lid.
The pressure is set at 3 atmospheres.

"I want to try it out."
"Yes, I think it's a good idea.
Erza immediately decided to try cooking with the prototype pressure cooker.
