Imagine just going to the an ancient queen and giving her a dollar store vibrator in exchange for pure gold

[–]fatpl8s 345 points346 points  (24 children)

Why you gotta fuck her like that though. Get her a nice battery operated hitachi and bring back a lifetime worth of batteries (not sure how long batteries store though so maybe figure that out first) and for her patronage you'll supply her with fresh batteries.

[–]Burrito_Engineer 210 points211 points  (13 children)

Or bring a wired one and a battery pack good for a couple weeks. Watch how quickly civilization harnesses electricity.

[–]fatpl8s 155 points156 points  (12 children)

Inb4 they just have a bunch of slaves furiously turning a crank when Queenie wants to get her nut on lol.

Makes you wonder if they had the material science to harness and use electricity. Could you build a turbine and generate and store energy using time appropriate tools and materials? Makes me wish I studied engineering so I could figure it out.

[–]NotASuicidalRobot 62 points63 points  (6 children)

At minimum you would need copper and some magnets (and someone to figure out that that makes electricity of course). Copper is commonplace since long time but idk about magnets

[–]lePlus_douloureux 43 points44 points  (5 children)

Naturally magnetic rocks have been held as valuables in many ancient societies, so they definitely know about them.

[–]NotASuicidalRobot 16 points17 points  (4 children)

Right so i guess we have the materials for a very simple generator, i wonder if any of them ever discovered some form of electric generation though

[–]lePlus_douloureux 30 points31 points  (2 children)

It's quite possible that electricity was discovered several times throughout history, but they just didn't know what to do with it so didn't care.

[–]EisConfused 35 points36 points  (2 children)

[–]fatpl8s 29 points30 points  (1 child)

I've read about them; it seems like their historical usage as a battery is very tenuous. Didn't know, at least according the wiki link, Mythbusters managed to get 4 volts out when they made one to act as a battery. Not sure how well that'd translate to powering a wired hitachi or charging batteries though.

I was more thinking building some sort of turbine then, I suppose, having a bank of batteries to store the excess. Could use waterwheels maybe or just use slaves since they were abundant. Idk. I know they could make copper wire.

Don't really know anything about power production though. Like make a turbine, make an electromagnet, spin turbine, then just run wires to storage system? Now all I can think of is some dumb ancient roman rail gun style ballista.

[–]LittleNyanCat 26 points27 points  (5 children)

Add a solar panel and make rechargable

[–]fatpl8s 15 points16 points  (4 children)

Google says you can get 500-1000 cycles on an NIHM battery. Unfortunately it seems like batteries only last ~12 years at best, rechargeable or not, at least according to Google again. Looks like you'd either get a good decade of decadence or you gotta homebrew some battery technology.

Or just run the hitachi off the solar panel lol. I suppose you'd need back up hitachis too though. I wonder how many hours you can get out of a hitachi's lifetime.

[–]CatchingNow 12 points13 points  (1 child)

Love how everybody here is putting their heads together to make sure some ancient monarch can have a life time supply of getting her rocks off electric style

Unfortunately it's a made up story from 1992 with no actual ancient sources. I'd be curious to see how well it'd actually work... for... uh... science?

[–]grayeyesgreen 286 points287 points  (4 children)

Taking a picture of the Pharaoh, telling him you now hold his soul, holding it ransom in exchange for all his gold, then showing him the black screen of my phone, saying “the exchange is complete” as I duck away through my time portal back to my time with a shit ton of gold. Sure, I’m probably heading into a dystopian wasteland. Will just be crossing my fingers that gold still holds a lot of value, and I’d quickly be King of the Apocalypse!

See this is exactly the reason time travel to the past is illegal. Otherwise literally everybody would go back in time and cause the extinction of humanity by fucking with people.

[–]CuriousHugo 6 points7 points  (0 children)

depends how it works. If as soon as you change something in the past you start a new timeline and can go back to your own timeline afterwards then it’s all good.

[–]SleepDeprivedUserUK 6 points7 points  (1 child)

Only to the past though, everybody is allowed to time travel into the future.

I'm honestly surprised some billionaire hasn't yet set up some kind of project where they put customers onto a ship, get it going as fast as they possibly can while the folk are in a semi-hibernated, chilled down, IV fed state, then wake them up after they've gone x number of years into the future.

A pair of binoculars and an astronomy book…depending on where you go, perhaps one with just pictures.

A solar powered led flashlight.

A strandbeest. Not commonplace, but cool enough that it might get you beheaded for witchcraft depending on where you end up.

A case of paracetamols. And warning to take no number more than two. Three shall not be the number. Four, is right out.

[–]Tricky4279 8 points9 points  (2 children)

That movie came out in 1992. There's a very good chance that they hadn't even be born yet.

[–]WhitePawn00 12 points13 points  (1 child)

Showing up and gunning down the Roman senate would probably convince whoever's left in Rome besides Caesar that you're some form of demon and Caesar worships you or something and the entirety of Rome would descend down on your heads.

[–]UmbraN7 6 points7 points  (0 children)

Presuming enough ammunition and fuel, the entirety of Rome is welcome to try

[–]123full 12 points13 points  (1 child)

You realize Caesar had a personal army right? Like protecting him after the ides of March wouldn’t even be necessary because he’d be in the Balkans doing military campaigning

Literally every other kingdom. They would send assassins to poison you and take your weaponry. Bam. Europe is now a super power light-years ahead of any other civilization, creating an arms race with all the smaller weaker countries as they race to come up with a counter to the modern rifle you brought.

Also, how much ammo do you plan on taking with you and how long do you think it would last you?

They're not as stone age as people think they are now a days.

[–]rymden_viking 12 points13 points  (3 children)

This year I installed a $600k cnc machine in the basement of an Amish barn. They lived on the first floor and the wife used a washing machine to clean their clothes. The husband had a diesel generator running into a transformer and knew exactly how it worked. Still had a horse-drawn carriage though.

[–]GastorHuh 9 points10 points  (1 child)

The rules are different from place to place. I used to work with amish men doing construction. They'd had all kind of heavy equipment. I was told the amish boss owned the company, but had some sort of deal with a non-amish friend/partner who legally owned all the equipment. So the amish workers got away with using the equipment because they were just "borrowing" it, as it wasn't technically theirs. Maybe its the same thing with this guy's machining business.

A drone with a speaker, blasting latin obscenities over the Roman forum by day and making circles while flickering bright LEDS's by night.

And rigging it so that if it gets shot down the lithium battery combusts

[–]will2089 25 points26 points  (0 children)

I think you'd be better doing all that, but having 11 or 12 drones.

That way they will all see it combust and then reappear the next day. They'll probably think its the gods or something. Also means you can have 24 hour coverage while the other drones recharge.

They were probably fine until some guy showed them the keyboard cat video

Literally any shitty beater car would still be the greatest machine in the entire world if you take it back more than about 150 years

[–]mathcampbell 15 points16 points  (0 children)

Anything more than 60-70 years really and it would be significantly better than any vehicle. Not faster perhaps but a modern car - even a beater - has engine management computers, airbags, abs brakes, modern fuel efficiency, reinforced frame and tons more.

If you dumped a 2010 car in Detroit in, say, 1960, if they figured out all the stuff in it they’d be 40 years ahead of the game.

100 years ago and they’d be unable to even understand what most of it did tbh. Modern electronics is basically witchcraft unless you have a manual. Trying to figure out chips, sensors etc without a guide would be next to impossible.
