A Fission Stirling Power Unit for Continuous Mars Surface Electricity: Conversion and Conditioning Sizing

This paper presents a sized design for a Mars surface system based on dynamic free-piston Stirling conversion of fission heat to alternating current, rectified and conditioned for a surface bus. A small fission reactor coupled to free-piston Stirling convertors delivering continuous power through dust storms and night. The study is SIMULATED, NOT MEASURED: all values are computed from stated assumptions and published Martian environmental data, and no hardware was built or tested. The principal computed results are electric power W of 10000, stirling efficiency of 0.32, carnot limit of 0.635, conditioning efficiency of 0.96. Further results include thermal power W of 32552.1, waste heat W of 22552.1, convertor units of 4, power per convertor W of 2500. The design is a computed study for peaceful surface operations — power supply, thermal control, radiation protection, construction and resource extraction for a crewed base — and it has no targeting or weapon application. Losses, deratings for dust and temperature, and the margin between capacity and the stated load are reported alongside the headline figures, and the limitations section states what a physical test would still need to establish.
