Abstract

In this article, the construction and performance of a small low-temperature differential Stirling engine is presented. The engine is connected to a small DC generator and tested with actual solar energy by using a parabolic-dish concentrator as a heat source. Engine performance tested with actual solar energy is reported. Variations of engine-generator power output, combined engine and generator efficiency, and overall efficiency with direct normal intensity are presented.
