My untrained ear puts the acoustical resonant frequency at
about 450 Hz.  If we connect a piston and crankshaft to
this thermo acoustic device, it certainly won't spin at
that resonant frequency (27,000 RPM!)

I wonder what would happen if we increased the size of
the 'hot reservoir' to the point that it matched the
equivalent loaded frequency of the piston?
(Say 3 to 5 Hz)?   Efficiency increase?  Probably.

My own biofuel project is within sight of completion and the lathe
deserves a more noble task than making repair parts to keep Chinese
appliances running.
