  • Solar energy concentrating and collecting arrangement and method
    Patent number: 3994435
    Abstract: A solar energy concentrating and collecting arrangement and method in which a semi-cylindrical oblong concave reflector/concentrator forms the roof of a house, school or other building, particularly a heat utilization building. A collector is movably supported in spaced relation above and along the length of the oblong roof/reflector, for pivotal movement to a zone of maximum confluence of solar energy rays reflected from the roof reflector as a result of variations of sun path during the various parts of the year and also to further accommodate each day's movement of the sun. Movement of the collector is by pivotal movement about an axis parallel with the center of curvature or curvatures of the roof/reflector and disposed adjacent the roof/reflector.
