Dancing Circles on the Horizon of Events

After breakfast. Waltz, Cortex, and Energia were having some discussions at the bridge. They were exchanging views on what was needed and what modifications would be made when energy made modifications to go into space.

"There are a few ways to get to space? You can use a rocket engine that gets explosive thrust to normally accelerate, or you can build a mass driver and force it from the outside to accelerate, or you can build a space elevator and take it directly to a stationary orbit..."

"But if you launch Energia, you can't use all that method ~. It's too heavy in the first place. This hull, from the frame, is a reinforced enchanted forged orihalcon alloy, and the exterior is a composite ceramic material that ignores weight gain. With about a rocket engine, you won't be able to float at all, even if you put on hundreds of them, and even if you built a mass driver, I think the rail will melt with current before it generates a decent acceleration. The same applies to elevators. Or do you think you can make such a big deal in a short time ~?

"That's right...... You can't realistically...... Is there any better way?

"As always, can't we use gravity control systems to use propulsion ~?

The hull of energy had risen in the air by using a heavily outputted gravity control system mounted inside it to resist gravity. As for Cortex, he seemed to think, as before, that it might be good in a way that uses gravity control systems to accelerate --

"If we go to a completely airless space, we won't be able to use a fusion reactor to create electricity, so we won't be able to use a gravitational control system that consumes enormous amounts of electricity."

—— As Waltz pointed out, the gravity control system didn't seem to work in space.

The nuclear fusion reactor itself is capable of producing an enormous amount of heat stably, both on earth and in space, as long as it is fuelled. However, power cannot be removed directly from heat. In order to create electricity, the generator (gas turbine) must be turned once the heat is converted into a high-voltage form of steam…. In order to reuse the finished steam in the gas turbine, it is necessary to cool the steam and return it to its original water again.

However, in space, heat cannot be discarded outside the hull because there is no air and it is a vacuum. The steam produced once heated remains steam for ever. When all the water in the steam circulation system evaporates, power generation becomes impossible.

Alternatively, there was no way of cooling the radiator of the steam circulation system by discarding steam in space, taking advantage of the phenomenon that the temperature of the gas drops when the gas at high pressure changes to low pressure…. Even in that case, it was difficult to say that it was an appropriate measure in the current situation, where it was expected to drift through space for a long time, because when water and steam were depleted, they would end up in a situation where they could not be cooled. It should be noted that energy can fly steadily in a thin, airy environment called the heavenly side of the world tree, because steam is cooled in this way.

"So what does your sister think we should do ~?

"I haven't thought about it, so I'm not setting up a meeting place like this..."

and waltz angry at the question from Cortex.

That's when energy mk1 and mk2 pinch their mouths in the discussion between the two of them. While Waltz and Cortex were discussing it, it seems the Energies were consulting each other at the Energies...... Seems to have succeeded in finding ideas to crack down on the current situation.

"Hey, sister."

"Hmm? Something?

'You can't use the generator at our house because, I mean, we're running out of water, right?

"Well... you're not wrong, are you?

Why don't you ask Lucia or someone to use water magic?

…………

That way, while we have the magic, we can move the fusion reactor, right? Besides, Lucia's magic power is enormous... so it's almost unlimited, isn't it?

If you run out of water, you can refill it... The method proposed by the Energy Sisters was as simple as nothing else. As for Waltz and Cortex, who were only thinking about replenishing the water from the outside, it seemed like a proposal for scales to fall out of their eyes.

"You're geniuses, aren't you? Magically make water to move the nuclear fusion furnace, or... I didn't have that idea. (Ice magic would be nice... but it seems like it's hard to control. If I make a mistake, there will be ice clogging in the tube and it will explode, and unlike water, I don't have to replenish it occasionally, I have to keep it cool all the time...)"

After thinking about whether you can use any other magic besides water magic... Having come to the conclusion that there was only water magic, Waltz began to talk about his concerns when he used water magic.

"But is it okay to use water magic on board? Where does magically created water come from? You're not collecting the moisture in the air on board, are you?

I also had some understanding of what magic was in the world and what effects it had, waltz that magic could not be used. Fire magic is the magic of heating an object, wind magic is the magic of manipulating the flow of air, transfer magic is the magic of moving an object to a position away, etc…. These are magic in which magic is converted into physical energy, just as the operator intended. As a waltz, there seemed to be little (...) to suffer from understanding.

But I didn't understand all the magic. The magic Waltz suffered from understanding...... The representative was water magic.

Anyway, the water of water magic came from "nil". Oxygen and hydrogen did not react, nor did the water that was in the operator's body stain out, let alone collect the water that was dissolving in the air... It was a magic that completely ignored the law of mass and energy conservation: water coming out of the empty space at the end of the operator's hand. If you can really create matter from nothing, you can even create gold if you devise it.

As for the anomaly of water magic, Cortex also seemed to have noticed. Just because she's been involved in magic longer than Waltz... He seemed to have his own answer about water magic.
