Stirling Solar Power Generators

Stirling Plant Engine

In addition to SEGS, ISCCS, PV, and updraft tower methods for collecting solar energy, Stirling solar dish systems are also used Figure 1.38 . These units focus the Sun's energy onto H2 in sealed Stirling engines. As the H2 is heated to 732 C 1,350 F , it expands and drives the pistons of the engine. Stirling engines are used on submarines because they are quiet no combustion takes place . In solar applications, their main advantage is their high efficiency 30 , which is nearly double that of...
