A high-efficiency residential solar thermal power plant for economically generating power from solar-thermal energy, using a parabolic trough mirror (210) having a longitudinal focal axis, for concentrating sunlight, a timer rotator for rotating the mirror (210) about the focal and longitudinal rotation axis to follow the sun, and a heat collector (220) surrounding a flow channel (288) that preferably has an oblong cross-sectional shape with a major axis aligned with a longitudinal plane of symmetry (213) of the parabolic trough mirror (210). The heat collector is coaxially positioned along the focal axis of said mirror (210) to receive concentrated sunlight so that a working fluid is heated and provided for use through an outlet end of the heat collector. |
