Ok....

What's wrong with hydro electricity, or steam powered generators...

I get it, I really do, it pollutes the fantasy aspects of the story. But if you are going so far as to introduce magitech vehicles, golems, and bio-mechanical prosthetics, generating electrical power becomes a less of a technical issue and more one of knowing a few basic concepts and the logistics to collect the needed materials.

MC’s brain stopped working for a moment after hearing Meiry and Yuufi’s explanation :dogkek:

Remember that the twins, despite their incredibly vast knowledge, aren't actually from Earth, so there's going to be quite a few gaps in their knowledge; they may not actually know about hydro electricity or steam power.

And Tohru is old enough, and has been in this world long enough, that a lot of the things he learned, either directly or through osmosis, may be just vague memories. In this case, it could also be a bit of knowledge he took for granted. Like, you tell any modern person you can generate electricity through steam or raw hydro power and they'll go "yeah, of course" without thinking about the how or the why.

They may not have a reasonable place nearby for hydro, and steam power does require a lot of fuel. Though considering that they can convert the power of magic stones to mechanical energy, they could just attach that system to an electrical generator to turn that magic to mechanical energy to electricity. There is no way that wouldn't be cheaper than the process they are talking about here, and it should be a fairly efficient process.

Really though rather than trying to avoid polluting the fantasy, it feels to me more like it's an excuse to separate the mc for other stuff, and have the twins continue to act as an endless source of esoteric knowledge.

Their knowledge of chemistry far surpasses anything a casual modern person would know, but that in itself feels more outlandish than this power stuff.

In the first place, they gave up too quickly for converting Tohru's electricity into a power source. Does the electricity still carry that magical resistance even when conducted from a long line of copper? What about to a battery? A transformer? Or use that electricity to power a different electrical engine.

While hydro probably requires too much space in this monster-infested world, they gave up a bit too quickly.

I would assume the issue of making hydro electricity is time and cost. As they said, it’ll take awhile to make and the cost of a hydroelectric dam is probably more than a single person can afford. After all, I don’t think a waterwheel size hydro power is nearly enough. From what I understand, we’re talking modern earth city amount of electricity to make aluminum.

Hmm so no windmiller? they are rather useful to make electricity and they are in an area where there are winds.
it is simple.. or force a golem to run on a treadmiller that creates electricity. i am amazed like the others in this tread that they gave up damn too fast.

I think hydro is out because of the terrain and the risk from machines, so the real question is: how does on boil water in this world? Can't they use magic to create steam and spin a turbine?

It would take ~72 Kwh to smelt 1 kg of aluminum. That's as much as a fully charged electric SUV, or powering a fridge for ~six weeks and I think this is where the author decide to copy/paste the Napoleonic aluminum recipe rather than muck about with early steam engine outputs and starting a new industry or three to support electric energy production. :aquadrink:

They could even just, boil water with it to create steam. What if they create Tohru bath water tho, then things would get really tricky.

damn, you beat me to it. I was just coming to say this exact thing lol

but yeah, economies of scale are also a thing. Most countries actually exempt their smelters from standard energy prices and restrictions and give them priority access to the grid because of how electricity intensive they are. So one person seeking aluminum in this setting, without looking to create a massive industry, needs a different approach as doing things "the way we would in reality" would be shoving that world entirely through the industrial revolution just to get access to some fancy lightweight metal for her personal projects.

That's why I said it was less of a technical issue and just one of basic concepts and logistics. Neither Tohru nor the Twins needs to know the exact method, just give the genius craftswomen the gist then turn her loose.

As above, it is less about the physical location or even the exact devices and more of the concept of generating electrical power with magnetism. Wind driven turbines would be just as viable as hydro or steam. So rather then a chemical process this genius gal would create a magitech macguffin to generate the needed electricity.

I can see your point, but think it's not relevant in this case. The author went with a convoluted Napoleonic era chemical process to purify bauxite into aluminum, which arguably would require a herculean effort and a much wider industrial base to scale to the needed levels. So it was never about the infrastructure needed to produce the aluminum and more about flexing their knowledge about this one obscure method to make said metal.
