A copper coil, a magnet, and a repetitive source of motion is not that hard. You’d have to go really far back not to have access to a mill, and even if you did, it wouldn’t be that hard to invent a hand crank. The question is how you make the electricity useful. I think a simple heating element is probably the best option. Show them the river cooking their food, and the benefits should be obvious
It won’t take too long for them to invent the porn machine.
That’s the first thing I’d teach them so I won’t be lynched for being a witch!
Rotating slide projector is also an easy one 😉
Tbf, I sincerely hope a lot of you understand the basic concept of a gearbox. Depending on how far back you go, a water wheel might be a pretty massive leap forward, and it might at least inspire other, smarter people of the time to work on theories of energy, and eventually electricity.
I would just bring an e-reader preloaded with Wikipedia and a solar charger. It would be treated as a relic for millennia long after it stopped working and would probably cause a collapse in the time-space continuum, but that’s just how I roll. 😎
I’ve seen enough isekai anime to know the way to make money is to show people clear glass, soap and the thing to pull water from a well without a manual bucket.
If you can research how to make the original microscopes, bringing an understanding of virology would be hugely impactful.
Honestly, you don’t even have to go that far. Just bringing back germ theory would massively advance the health and safety of ancient peoples. You might get a little bit of pushback trying to explain it to them though.
Germ theory was around for a long time before it was adopted because no one believed it.
Hello, it’s me from 2025. When are you from where germ theory is finally believed and acted upon by the majority?
People don’t poop in their drinking water, it’s an improvement.
Not in the 2025 I’m from! https://www.cbsnews.com/news/supreme-court-epa-san-francisco-sewage-discharge/
I’m pretty sure that’s just precision grinding glass and setting it at the right distances.
But getting the precision shape to grind in can be hard. There was something about dripping liquid glass just right, but that may have been professional espionage to throw people off.
Oh for sure. I’m ready in case they pick me to go back in time and push human technology forward.
jokes on you, I watched dr stone
While I have a basic understanding of using magnets and wires for motors/generators, I think an easier option would instead be a Van de Graaff generator.
Then probably get executed for witchcraft or just ignored as a lunatic for speaking in a strange foreign tongue.
Now I’m wondering how the first coil was made, because that doesn’t seem like a job for a forge
If the apocryphal kite experiment is to be believed, wet string.
You absolutely can make wire with just forging techniques. Not sure how far back, but a celtic torc can be made with many thin strands of metal, this sort of thing is more likely a question of how many 1000s of years ago were they able to.
you make a wire, you coil the wire
I think my go-to invention would be some kind of bicycle or something that uses a similar mechanism
If you accept a lack of gears, a belt drive instead of a chain probably simplifies the most difficult part of actually making it. Best pick somewhere with good roads though, since you’re definitely not making pneumatic tyres or a pump to fill them with
Shaft-drive bicycles are a thing too. That might be easier for an ancient blacksmith to tackle?
Edit: or to at least get a proof of concept you could bypass the whole torque-transmission issue by building a penny-farthing
I thought about something that stays in place, maybe a small millstone or a blower for a smith’s forge.
After that take this rock and show me how you taught it to do maths
