I don't know what the question is, are you asking if anyone's designed a specific system for the coming zombipocalypse, or has anyone considered how when the crap hits the fan we're going to declare ourselves the "Kings of the Sacred Barley water" and trade nubile slaves for our wares?
Zombipocalypes brewing threads on here are like flies on horse****, or threads about bacon, there's tons of them on here. I've probably got three of them on here myself.
The answer's pretty obvious, it's just the entire 45,000 year history in reverse.
Pretty much we'll be brewing with propane and turkey fryers like we do now, until Propane runs out, then we'll be back to how it was done in the 1800's-
