Tuesday Torque: Fascinating To Watch

Hot air engines have been around for a long time and I still can't get my mind around the inner workings.  They are quiet, and have a history of working in remote places where fuel supplies were not a  sure thing.  Build a fire out of whatever and it will spin.  Maybe  not a lot of torque, but a lot of action.
