Which outcome arises when a low-friction Stirling engine operates near theoretical Carnot efficiency?

💡 Explanation

Perfect Carnot efficiency requires isothermal processes, but isothermal heat transfer needs infinite time to occur with a finite temperature difference; the finite temperature gradient lowers performance because irreversible expansion supplants theoretical equilibrium, rather than increasing stress.
