The Stirling engine has fascinated engineers for more than two centuries because of the elegance of its principle: heat on one side, cooling on the other, and motion created through balance and timing.
This cross twin-cylinder model takes that idea and makes it more visual.Instead of relying on a single moving cylinder, two heated cylinders work in symmetry around a central flywheel. The result is smoother movement, stronger visual balance, and a mechanical rhythm that feels almost architectural.
