No,not me, it's the name of the engine :roll: Stirling engine plans from Machinist Workshop, October 2003. My firstborn. It's a little sloppy, but it runs. I know how I'd like to tune it up, but I hate to take apart the only one I have that runs. The displacer is not very precisely made; and the balloon that forms the power piston, orange in the picture, is not flexible enough, next one will be latex from a disposable glove.
