something people writing post-apocalyptic fiction always seem to forget is how extremely easy basic 20th century technology is to achieve if you have a high school education (or the equivalent books from an abandoned library), a few tools (of the type that take 20 years to rust away even if left out in the elements), and the kind of metal scrap you can strip out of a trashed building.

if you want an 18th century tech level, you really need to somehow explain the total failure of humanity as a whole to rebuild their basic tech infrastructure in the decade after your apocalypse event.

i am not a scientist or an engineer, i’m just a house husband with about the level of tech know-how it takes to troubleshoot a lawn mower engine, but i could set up a series of wind turbines and storage batteries for a survivor compound with a few weeks of trial and error out of the stuff my neighbors could loot from the wreckage of the menards out on highway 3. hell, chances are the menards has a couple roof turbines in stock right now. or you could retrofit some from ceiling fans; electric motors and electric generators are the same thing, basically.

radio is garage-tinkering level tech too. so are electric/mechanical medical devices like ventilators and blood pressure cuffs. internal combustion’s trickiest engineering challenge is maintaining your seals without a good source of replacement parts, so after a few years you’re going to be experimenting with o-rings cut out of hot water bottles, but fuel is nbd. you can use alcohol. you can make bio diesel in your back yard. you can use left-over cooking oil, ffs.

what i’m saying is, we really have to stop doing the thing where after the meteor/zombies/alien invasion/whatever everyone is suddenly doing ‘little house on the prairie’ cosplay. unless every bit of metal or every bit of knowlege is somehow erased, folks are going to get set back to 1950 at the most. and you need to account somehow for stopping them from rebuilding the modern world, because that’s going to be a lot of people’s main life goal from the moment the apocalypse lets them have a minute to breathe.

nobody who remembers flush toilets will ever be content with living the medieval life, is what i’m saying. let’s stop writing the No Tech World scenario.

the thing *I* get mad about is no one goes and fixes up any of the hundreds of thousands of airplanes lying around, or even puts together any new ones. like the big fucking stumbling block for all those thousands of years for humans seemed to just be no one managed to combine the idea for a propeller with an engine that would spin it fast enough. but now the genie is thoroughly out of the bottle: drawings of planes have the propeller on it. we will remember that the secret to airplanes is smallish airfoil wings and a very very fast propellor (or three) for a thousand years, until all the books and drawings and planes themselves have decayed away. 

like yeah you couldn’t make commercial jetliners in your garage, but if you camped out in an old airfield, you could probably bang together some kind of working franken-cessna.
