ABSTRACT:
Recent work by this author demonstrated that the Ringbom Stirling engine is particularly well suited for operation at small temperature differentials. This pointed to the possibility of operating Ringbom engines from direct unfocused or from moderately concentrated solar energy. This paper

describes a small low temperature differential Ringbom Stirling engine designed and constructed to test direct solar operation and collect operating data. The paper includes a discussion of scaling equations derived and used in the analytic design of the engine and details of its construction. The concept of a conical reflector used as a low power solar concentrator is introduced and the design and construction of an experimental unit is detailed. Results of the conical reflector on engine performance are presented. Show Less
