You've got a degree in ancient Sheikah engineering, don't you? I'm curious, what powers the Divine Beasts? Must be something powerful if they can be dug up after 10,000 years and not need refueling...
The Divine Beasts are fuelled by a complicated knot of intertwined Ancient Sheikah tech! I couldn't possibly explain it to a layperson
WELL IT IS but more in a practical sense of categorically and straightforwardly...
I didn't make the damn things! And the blueprints were very secret even then, as well as the first thing to go after then Princess decided she was done with the idea.
There are Environmental engines on The Beasts! I saw Vah Medoh generates some energy from wind turbines, I imagine Vah Ruta has some thermal ones and Vah Rudania might have some lightning catchers.
But that is definitely supplemental, for efficiency and energy recycling. I can't imagine something like that fueling SOMETHING LIKE THAT.
Main fuel is probably the same blue juice Ancient Sheikah were putting into everything back then - processed Light. And yes, pay attention, it's Light with a capitalized L. That stuff reacts to people, not things. So if properly sealed it could last until the the end of time. And no wonder it didn't get spent after 10 000 underground. Not like the Beasts were moving a lot down there.
But that's fuel! I wouldn't say it "powers" the Divine Beasts.
Fuel is just a part of the mechanism. No more no less then all the movy-pushy piston thingies. Can you really say something ""powers"" a machine if it can be full to the brim with the stuff and still immobile?
Nah, what "powers" the Divine Beasts for real are the pilots
Unlike Guardians, which have a simpleton free will of their own, The Big Guns wouldn't move an itty bitty inch without them.
Without pilots and empathic cores I mean. The craziest part of the whole Divine Beast project.
At once ludicrous and elegant solution to the problem of "We want Sages to operate these giant complex machines, but we can't have them trained as machinists for 3 decades."
The ancient Sheikah just made it so the machines in qestion could agree with the pilots! Easy! Simple as creating an artificial intelligent personality that instinctually feels its enormous mechanical body, but lacks a will to move it. As well as a telephatic link between it and a person, so all a Sage really needs to operate a Divine Beast is to "hit it off"™ with their ride and for the two of them to agree on what the Beast should be doing at the moment.
Pish-posh, easy-peasy, banana-squeezy. Developed and built the whole thing on a weekend afternoon, no sweat, no issue.
Totally didn't take a life time of effort and dedication form the greatest Sheikah minds of the time, maybe of all time, to complete. Perfect thing to use once and burry out of sight, out of mind.
