  Let’s see… electricity in a preindustrial environment. You’ll get into Factorio levels of invent a tool to make a tool to make a tool…

  Copper wire existed at the time, (depending on the time period) but drawing it involved a person on a swing pulling it through a hole in a metal plate. So we need a metal plate. Surely there is a town blacksmith? We will need a few plates with gradually decreasing hole diameter. Enough wire for a demonstration would be difficult and expensive, but not impossible. Could also use copper busbars instead of wire.

  Now that we have conductors, we have to figure out what method of generation we want. Rather than trying to make bearings, balanced shafts, and stacks of thin metal plates all identical and radially symmetrical so we can make a generator, we should first attempt a battery. For this we can get away with stacks of two dissimilar metals in a glass or ceramic jar, bathed in some sulfuric acid. Aqua Regia was a mixture of nitric acid and sulfuric acid, but it might dissolve copper and zinc plates. Could also use lead plates, those are easier to hammer out flat. With this we could get an output around 2v per cell, put a half dozen of them together in series and one could build a simple arc lamp.

  After the proof of concept demonstration, hopefully you’d interest more smiths in the project, increasing your talent pool. With some mercury and wire you could build a version of Faraday’s homopolar motor.

  After that I’d probably be burned at the stake.

  It isn’t so hard really, to make electricity even in the olden days.

  A dynamo is just a copper wire with a magnet spinning inside.

  Making a copper wire you can accomplish by having a hole at the bottom of a kiln that drops directly into a big vat of water. Or even just drawing a line in the sand and pouring it in there.

  Getting your hands on a natural magnet might pose more problems, but ultimately those are found in nature. So they should have already been dug up by someone.

  Using the electricity usefully is harder. Since creating a light bulb needs access to gasses. What could we even use the electricity for?

  source

  • Marcbmann@lemmy.world ⁨1⁩ ⁨year⁩ ago

    If you can make a dynamo, you can make a motor. Now, you aren’t about to create Tesla. But there’s plenty of things back in the day that could benefit from being motorized.

    • Comment105@lemm.ee ⁨1⁩ ⁨year⁩ ago

      Could you also do ac/dc conversion ti make the electricity useful elsewhere? I’m guessing charging and transporting primitive batteries won’t be able to fulfill any useful purpose at all.

      Also making carbon Zink batteries should be possible, so a handheld fan would definitely be a possibility and would already be mind blowing

    You can create light with electricity with two carbon rods to make an arc light. It was literally the first electric light source and in widespread use for a long while, along with incandescent bulbs.

  There was a short story I read ages ago in some collection somewhere I’ve been dying to find. I think it was from the 60s or 70s, but a scientist brings a man from the future and the man is just a normal guy, so he can’t explain anything to the scientist’s satisfaction and the scientist gets more and more exasperated.

  The dialogue was like:

  “What is the dominant mode of transport in the future?”

  “Oh, we fleem.”

  “Fleem? What’s fleem?”

  “It’s a kind of garbol but with more slimp.”

  “Okay, never mind. How do you do it?”

  “Oh, that’s easy, you simply merfingle the blem and you’re fleeming away!”

  “WHAT IS THE BLEM?!?”

  For anyone interested a simple way is to wrap copper wire around a magnet. Static electricity was also one of the first ways people started noticing electricity.

  • atyaz@reddthat.com ⁨1⁩ ⁨year⁩ ago

    Even if you studied it, the answer boils down to “magic”.

    You take these magnets, and move them around these long snakes of metal (because electrons can move easily through metal) and that makes the electrons in the wires move.

    Okay, why does moving around a magnet near metal make something inside it move?

    Well there’s something we call the “Lorentz force” which basically pushes a magnetic thing in a specific way if you move another magnetic thing around it

    But why does that happen?

    Magic

    source

    • Mchugho@lemmy.world ⁨1⁩ ⁨year⁩ ago

      It’s all attraction between opposite charge and repulsion for the same charge, even magnetism. Magnetism is just charge in another gauge.

      What I mean by this is from our perspective we view a moving charged particle as emitting a magnetic field, but if you were to move along with the particle at the same speed it would be observed as being at rest and emitting an electric field.

      Not really though. You can say that about anything if so. If I don’t understand why atoms exist, does that make the universe “magic”?

      I mean I get what you’re saying kind of, but understanding the basics of electrical power is not the stuff of sorcerers.

  • Elivey@lemmy.world ⁨1⁩ ⁨year⁩ ago

    I mean, from this thread it shows people kinda remember stuff from those classes, but are missing a lot. Which is understandable, people left school and didn’t use that information, it doesn’t make you stupid.

    But then you think, oh yeah! I remember how to make electricity, I need copper and an iron rock! So you spend all this time trying to manufacture some relatively thin copper wire, iron would probably be a little easier to find, wrap it around and then you’re like… Okay what went wrong? Annnnd you can’t remember you actually needed a magnet and you gotta spin it.

    Then do you remember learning how to store it? Connect it to anything useful? Maybe kinda, but extrapolate the first situation to every topic ever and that’s what you’d get, half baked ideas that you don’t really remember the specifics of. And the specifics really actually matter lol.
