I like the way the cyclone engine heats the steam (water tube) Reminds me of the Besler. and some steam car that competed witht the stanley steamer can't member name.

But in the end it is a PISTON engine! this means that chunks of heavy stuff need to fly at high velocity one direction and then at just as high velocity in the other direction and do this hundreds or thousands of times per minute. Not an efficient movement no matter how you produce your steam.
Why not a turbine? Even a slow turbine would need to be geared down to turn a generator and would run at a specific RPM eleminating the need for complex throttle controls.
