IIRC, Otto, Diesel, and turbine engines are all approximately equally efficient at rated output. Turbines have disgusting throttle lag, and poor fuel economy at partial throttle. (Which makes them a very poor choice for a prime mover in a traditional vehicle, such as the old Chrysler turbine car.) These factors would be null for a single-load-point system. (Diesels are the most efficient at partial throttle, which makes them ideal for a prime mover in a traditional vehicle.) Turbines that generate thrust directly are fairly thirsty. But those used in turboprop aircraft are not. The system I envision uses a high-rev alternator instead of a geared-down propellor to take power off the turbine.
The high revs of a non-geared turbine makes for good power density. The lack of a cooling system makes for a smaller system, increasing the overall power density. The resulting package should be small. And light. We're only talking about maybe 20HP total here. But, I'm not a turbine engineer. I could be wrong. -- Jim > On Jun 26, 2022, at 9:26 AM, OK Don via Mercedes <mercedes@okiebenz.com> > wrote: > > AFAIK, turbines are insanely thirsty. > > On Sat, Jun 25, 2022 at 1:54 PM Jim Cathey via Mercedes < > mercedes@okiebenz.com> wrote: > >>> Aside from the pollution caused by making the batteries, I think the >> real solution is a plug in hybrid with a small Diesel engine.
