The Technology That Kept Humanity Alive In Frostpunk

[@Zippsterman]

When you say 'pump out heat' I think it's actually more literal than you implied. The generator is built on top of a huge geothermal heat source. I think it acts as a ground-source heat pump, a sort of air conditioner in reverse (Technology Connections has great videos on this), delivering more heat energy than would be obtained by just burning the fuel directly. In FP2 this would be why the colony furnaces don't get as much heat for the same amount of fuel consumption as the generator cities. The heat is then distributed throughout the city by steam/hot water pipes where all those pipes and fittings you see covering the buildings run radiators to spread the heat inside the buildings, which in my thought includes snow melting pipes on the rooftops instead of the generator/hub just working as giant radiative heaters, which would also double as water collection sources from the melted snow (gotta get it from somewhere right?). Of course the area around each generator/hub would be nice and toasty warm from radiative heat anyways, so that's where everyone hangs out when they're not in a building somewhere. Cool video, subscribed and excited to see what else you may come up with I also just realized something - at -50 C is about 4/3 the density as it is at room temperature around 25 C. That means any sort of airship lifting gas, whether that be helium, hydrogen, or most likely hot air, would have greater capacity than was the norm in history - if your ship can suddenly be 1/3 heavier in total, but most of it was already just ship weight, your payload actually increases way more than 1/3. Airships suddenly become much more viable, so long as you can account for the winds trying to batter you around the place.
