if you think the trope of "ridiculously big gears in steampunk factory" was artistic freedom, nope!
check out the rest of the channel, it's got a ton of very well documented steam-powered factories
uh, wow. Got a lot of thoughts and feelings after checking this out, maybe one of the most... polarizing? iunno things I've watched in recent memory. Fascinating stuff.
Oh and it's also amazingly powerful for getting the creative juices flowing: artists come feast. This one's going in the ref library for sure.
