It doesn't idle efficiently, but the Army was sold on compactness, low smoke, and low maintenance: http://www51.honeywell.com/aero/common/documents/myaerospacecatalog-documents/SurfaceSystems/ Cheers -- MrG / http://www.vectorsite.net M1 Abrams tank is turbine-powered.

They also have _very_ low torque at startup and low RPM's. They are efficient as all get out when you want something to sit and spin at a high, continuous speed (ships and power gen), but not in less controlled environments. Even locomotives, which come closer to these ideals than autos, have had little success. There has been, in better than 100 years of tinkering, exactly one successful steam turbine locomotive (the LMS Turbomotive: http://www.dself.dsl.pipex.com/MUSEUM/LOCOLOCO/turbom/turbom.htm) and none powered by gas turbines. Practical hybrid electric drives may cause some resurgence in this system as they eliminate the direct connection between the wheels and motor and could insulate the turbine from sudden throttling up and down, allowing it to spin continuously at it's most efficient speed while the battery pack sucks up excess juice or aids in startup.

I was lucky enough to see one at a local shopping mall. When they started it up, it sounded like a vacuum cleaner, very smooth, a beautiful car. They loaned several of them to families to get feedback. I believe one of the problems was that they didn't have the quick response of a regular engine. Yes, Chrysler made turbine prototypes.

I presume they didn't catch on. Chrysler made prototypes of turbine-powered cars in the 60s. I presume they didn’t catch on.

That's kind of backward looking for 1947. This is a pulse jet isn’t it? That’s kind of backward looking for 1947.
