QUESTIONS How could electricity be made feasible through early medieval technology?
Could it capable of producing enough electricity to light a just a few rooms within a two-story building? Perhaps an entire building?
I expect it to work locally not spread throughout a city, and to be a rare luxury, the equivalent of a status symbol.
If this is not possible and considering it is in a realm of fantasy, could an extremely rare "magical" mineral the equivalent of a room-temperature superconductor make continuous electricity viable? Or maybe some other kind of element, only theorized by physicists of our universe to exist?
How else could this effect technology and culture in the world, considering its availability?
MY WORLD has gone through an apocalyptic era, where most advanced technology was lost, and through several major events magic was discovered. The advent of magic cataclysms brought rare, "magical," and minable minerals. Some in our universe which are only theorized by physicists to exist. Five thousand years later, the current era is the equivalent of an Early Middle Age.
I have read the materials for creating electricity in The Early Medieval period were available, yet it would not have been able to be put to any significant use.
Here are my theories based on some light reading and (mostly) my imagination. All of which I believe would be certain consequences and limits of the medieval electricity.
Electric Lighting as a Luxury Item Electric power would be at its infancy stages, unable to power large stretches of land, but perhaps several rooms in a large manor. Such a feat would be considered a luxury reserved only for the elite, being in itself a status symbol. So an electric powered light source would be in common areas or bedrooms, while candle light would still be dominantly used.
Dependency on rushing water as power source This would mean that the electric lighting in a buildings requires a river and water mill. Could this be worked around with something like a water wheel generator within a building and a complex system of piping water?
Requires rare and expensive minerals
NOTE I am hoping not to completely upend civilization with this technology or cause an insane surge in technological progress. At least for now, my world is supposed to have major limitations to any sort of progress to industrialization.
