Since he is talking about using a flywheel, a compound piston motor would probably be a good fit.




Low speed and low noise. Slower moving parts, less wear and tear when things come apart. [img]<fileStore.core_Emoticons>/emoticons/wacko.png[/img]/emoticons/[email protected] 2x" title=":S" width="20" />

Indeed.  Fairly large flywheel, fairly low RPM, alternate pole permanent magnets set in a groove along both sides of the rim, racks of coils set along both sides.  Very similar construction to the old low-speed pump motors on the New Orleans levy pumps.  But mounted horizontally; otherwise the gyroscope effect would make steering stupid squirrelly.  




The point of "hybrid" is 1) Constant engine speed.  No issue "coming apart" at 95 mph.  2) Load leveling.  High power on demand; charge batteries waiting at stoplights.  3) Power curve.  Ever seen the video of the Tesla getting off-the-line?  DC electric motors develop maximum torque at stall.  The only limit to stump-pulling is tire traction, only limit to top speed is not throwing the windings off the armatures.  




And a low-mass boiler, with separate tank.  So wait time isn't 30 minutes.  And, um, minimal effect if there's a boiler explosion.  "Better call AAA". . . .
