Only partially linked to a guy’s previous Harrier-style Air powered RCS post (https://www.simplerockets.com/Feedback/View/rxv353/Tap-off-pressure-from-jet-turbines), I would absolutely be hooked to see a jet turbine in general which could power that post’s idea, as well as having the opportunity to provide electricity to ground vehicles without having to directly add an engine into the game. Instead of thrust a Jet turbine should provide electricity which either directly powers a vehicle, like a turboshaft application, or a battery powering electric vehicles so tanks and rovers would not have to weigh so heavy due to having a battery. As another possibility, they could be run on Kerolox when not being used in an oxygenated atmosphere as well as jet fuel.
