R&D on small solar Stirling engines TNT-2 and 3, NAS-1
Abstract
A unique 1-kW solar Stirling engine, the TNT-1, 2, and 3, is tested utilizing the internal solar heating method. Two solar concentrator dishes are tested for a prototype for future large solar Stirling power plant systems. These Stirling engines have transparent cylinder heads at their top made of quartz glass, and the solar beam concentrated by the solar dishes heats up directly the inside meshes installed upon the displacer piston, penetrating through the quartz glass. An atmosphere hot air Stirling engine NAS-1 is under test, which has rubber diaphram power piston and quite simple construction.
