  • Regular trains don’t run underground. Lots of opencast mines exist .

    Basically all mines have an above ground terminal where whatever you mined is unloaded from your underground trains, lifts, haul trucks or whatever else onto storage piles, then loaded onto the actual long distance trains.

    If the mine entry is up a mountain, then the trip down from that point will be a net energy producer regardless of anything else.








  • There was rampant cannibalism in Polynesia along with all kinds of infighting. Maori gods have plenty of murder and war in the mythology.

    War in Asia goes far wider than just one empire. Imperial Japan were thoroughly tyrannical during WW2, as well as many other conflicts.

    Any civilisation that could spare, mobilise, and feed enough people to form an army basically did so, sooner or later. It’s a supply lines and population problem. Small populations can’t raise large armies and send them long distances.



  • Converting between Kelvin and Celsius is simple addition; converting between Rankine and Fahrenheit is simple addition. Converting between the two groups requires multiplication, and pre calculator, that’s notably harder.

    Also, all your kJ/kg/°C or BTU/lb/°F tables and factors are identical when you swap to referencing absolute zero. If you change to the other unit system, all that goes out the window.
