The " Steam Rankine Stirling Engine" (SRSE) is a Stirling engine assisted by steam or compressed air injection. So, this engine works in the combination of Rankine cycle and Stirling cycle, so that it is called SRSE. Until today, small size SRSE of double expansion was made first and, experimented by air and steam. Using 0.8Mpa air, about 70 watt output were measured which value is several times higher than usual atmospheric Stirling engine of the same size. New 3kW SRSE was designed and manufactured, which is designed to use wooden pellets and tips as fuel with l.OMpa steam. Now it is under tests and improvements. Already about 1.5kW DC end power was measured using 0.7Mpa steam. This engine would be developed into many ways for utilization of various biomass and other renewable energy sources.
