That's very clever. I can see indeed that we could undo in the isochoric
depressurization what we did in the isochoric pressurization step, at least
for an ideal device.
Now what is such a device (I'll accept a real one and idealize it in my
mind), and why don't intro textbooks mention it given that this seems a
pretty essential part of non-Carnot cycles?
Isn't that the metallic gauze piston that sweeps the internal space of the cylinder of a Stirling, in turn heating and cooling the charge??
