ABSTRACT:
This study resulted in a conceptual design of a free piston solar Stirling engine-linear alternator which can be designed and developed to meet the requirements of a near term solar test bed engine with minimum risks. The conceptual design was calculated to have an overall system

efficiency of 38% and provide 15kW electric output. The free-piston engine design incorporates features such as gas bearings, close clearance seals and gas springs. This design is hermetically scaled to provide long life, reliability and maintenance free operation, An implementation assessment study performed as part of this study indicates that the free-piston solar Stirling engine-linear alternator can be manufactured at a reasonable price cost (direct labor plus material) of $2,500 per engine in production quantities of 25,000 units per year. Opportunity for significant reduction of cost is also identified. Show Less
