    steam is alive and well its just produced and consumed on humungous scales that most people dont see

    theres no better way to transmit gigawatt scales of thermal (and therefore rotational kinetic) energy short to medium distances

      Always wondered why diesel was used for trains instead of steam. Always figured it was a gas industry scam.

        diesel is safer cheaper easier to operate way less maintenance and more fuel efficient

        only advantage (in railroad anyway) that steam has is cool factor and back in the day waaaay more power but modern diesel electrics with ac frequency drive trounce any amount of tractive force a steam rig can make

        although its perfect for railroad diesel is ony efficient up to a certain scale and then theres lots of logistical issues where steam & gas turbine power are more feasible

        believe me this kinda shit is my bread & butter no scams just good progress

          I dont know enough about it to argue, the diesel passenger trains around where I am run the engines at full RPM all the time, even when theyre sitting still. I take the train all the time, sometimes its a diesel.

          They dont seem too efficient, but I also have no clue about fuel efficiency of different trains so I cant really say anything about it.

            the engine drives a generator and they run at a constant rpm but as the driver calls for power the load on the engine increases

            youll hear the engine get louder and the turbo spool up

            and thats when they swill the fuel compared to usin fuckall at idle
