ABSTRACT:
A solar power collection system capable of operating with a positioning system that provides movement of the system about only a single axis of rotation. The solar power collection system includes a concentrator having at least one parabolic-trough-shaped mirror that focuses sun light reflected therefrom along a longitudinal focus line defined by a focus of the parabolic-trough shaped mirror. An absorber having a heat absorbing tube and a heat absorbing shoe is supported from the mirror such that the tube is positioned coaxially along the focus line to receive reflected sun light. The tube absorbs thermal from the sun light and conductively heats the shoe. The shoe supplies this thermal energy to an energy conversion engine. The engine, in one preferred form, is a Stirling engine that converts the thermal energy into electrical energy. A pointing system moves the concentrator about a single axis of rotation to track the sun across the horizon.
