Not due to environment, all kinematic (=Siemens style 4 cylinder alpha arrangement) are fundamentally flawed due to highly stressed non-lubricated piston rod seals that only last a few months in continuous use.
Alternative free-piston engines (eg infinia) are screwed due to very high tolerances required for gas lubricated bearings/seals and low speed heavy generators. Stirling engines are the perpetual bridesmaids of the heat engine world. Cyclone power looking good if they can deliver the 30%+ eff promised.
