Abstract
The invention described herein is a Method and Process for the direct absorption of radiant solar-thermal energy by and within a radiant-heat absorbing fluid. More specifically, however, it is a total system for the direct absorption of radiant solar-thermal energy and its conversion, for the purpose of generating useful mechanical or electrical power. Wherein within the scope of the total system, a radiant-heat absorbing fluidic compound is used which comprises minute particles of colloidal size, suspended within a transparent heat-transfer fluid, having a high boiling point and being circulated within a first highly light-transparent and a second highly light-reflecting wall. Wherein that fluidic compound's optical density is such that incoming concentrated, radiant solar-thermal energy, after penetrating said light-transparent wall, will penetrate no more than one and three-quarters depth of said contained, circulating fluidic compound.
