If one used a magnetic clutch, one could completely enclose the stirling engine with the only seal being the Schrader valve.
The benefit here being good being no seals against a moving shaft, so that be very simple I would suspect.
Has anyone tried this?

Looks like someone patented the idea back in 1996:

Magnetic couplers are nice. But the designer has to make compromise between weight and torque.

I think Andy Ross mentioned a magnetic coupling he tried on one of his motors in "Making Stirling Engines".

Yes. He did with his 230w engine. Magnetic coupling can also transmit high power through a thick "semi" magnetic medium; but not the way he did it.
