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?

Marcbmann ,

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.

Rubanski ,

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

Comment105 ,

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

HardlightCereal ,

You should watch Dr Stone

Destraight ,

This is exhilarating

dustyData ,

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.

Comment105 ,

You just invented cumbersome fire. Ugh ugh. No good.

dustyData ,

And we illuminated streets and factories with that for half a century.

Comment105 ,

I’m a caveman, I have night vision, why need pretty lamps?

NOPper ,

You use it to charge your phone, duh.

PersnickityPenguin ,

Electrocuting elephants?

CADmonkey ,

You can run a carbon arc lamp without glass bulbs, and without a huge voltage.

OriginalUsername ,

You spin the turbine, duh

If you went back in time and tried this, most civilizations would probably burn you at the stake

Is this a repost? Has lemmy already entered the repost phase?

Sami_Uso ,

I mean, could you imagine? The horror…

PatFussy ,

Say no more, ill repost it 1 more time in your honor

Papercrane , (edited )

First of all, no one would understand you, but how someone already pointed out, make a spool with copper and spin it. For bonus points, put a iron slab inside the spool

Edit: as someone pointed out you kinda need a magnet

hypertown ,

Plain copper will get you nowhere. Adding iron slab also won’t help. You have to have magnetic field to generate electricity

bloubz ,

Why wouldn’t they understand? People speak other languages than English

Ever tried Chaucer? And he was only 14th century.

bloubz ,

English has changed a lot (no I’ve not read a lot of poetry in languages other than my own), some others may have changed less. Maybe Aramaic, Hebrew, Arabic. Greek has changed but some people know ancient Greek

@Swedneck@discuss.tchncs.de avatar

eh language barriers are generally overstated i think, people with completely unrelated languages develop pidgins within the decade, and if you’re dropped into a place where they speak some complete gibberish like french you’ll still just naturally figure it out given a year or so of being forced to endure it.

Papercrane ,

That is very true, but maybe they would just kill you or think that you are crazy before you would have the chance to actually change mankind

Swedneck ,
@Swedneck@discuss.tchncs.de avatar

maybe, but frankly i think it’s at least equally likely that they just see you as a blessing from the heavens and frankly get a little too enthusiastic about your knowledge.

Ok, I’m in let’s be technology jesus

Just bring an encyclopedia with you, history of human advancements and history of human equality if you want to improve equality as well

Something to do with turbines.

Water wheels seem to spin a turbine. Maybe it generated current or something. Similar with windmills? Gyroscope or something.

Solar ? Quite clearly magical and a heretic, likely to burn me at the stake. Steam power pushes steam through A turbine maybe ?

Lightening sky electricity. Get a bunch of metal and kites. Die.

edinbruh ,

Solar are LEDs. But instead of putting electricity into that light comes out, you push the light in to get electricity out.

DarkDarkHouse ,
@DarkDarkHouse@lemmy.sdf.org avatar

Photovoltaic isn’t the only solar. Probably much easier back then to direct mirrors at a kettle to drive a steam turbine.

WarmSoda ,

You’re thinking of steam.
Create enough steam to turn a turbine that turns a magnet wrapped with copper.

Fun fact, nuclear power is just a powerful way to create more steam.

Mojojojo1993 ,

Ah. So turbines are steam. So ,magnets are key. Magic metal

RiderExMachina ,

Spinning an iron bar between another iron bar wrapped with one thin copper piece makes zap light.

It also makes a magnet for convenience.

Mojojojo1993 ,

So magic ? To the burning pile

RiderExMachina ,

Joke’s on you, that’s my fetish

Mojojojo1993 ,

Kinky

TrickDacy ,

Did you skip 3rd grade (and all other) science class?

atyaz ,

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

TrickDacy ,

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.

Mchugho ,

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.

atyaz ,

No it’s actually summoning demons

InternetCitizen2 ,

Idk man Jackson’s Classic Electrodynamics left me feeling like a jock in calculus.

Elivey ,

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.

Carlo ,

Such a good book. Wish it would stop being relevant.

WarmSoda ,

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.

Parlor tricks might be able to get you far when you time travel to the ancient past.

Pizzasgood ,

Wrap it in the wire, then spin one of them. That part's important! Won't do anything if you don't spin it.
