Stirling engine (3D)

About this app

Heat becomes motion: a running cutaway model of a Stirling engine with a hot and a cold side, displacer and power piston 90° out of phase. The gas visibly migrates between hot (glowing) and cold (cooling fins); a live p-V diagram shows the cycle. Temperature difference and speed adjustable (Carnot efficiency).
