  • Polar axis solar collector
    Patent number: 5275149
    Abstract: A polar column solar collector for use in association with a building, the system having a concave mirror located on the exterior of the building and defining a focal point and a central axis, a mounting column secured to the mirror coaxial therewith, a polar axis column, a hinge swingably connecting the mounting column to the polar axis column for moving the concave mirror to aim it directly at the sun at least over a predetermined period of the daylight hours, a secondary reflector located at the focal point of the concave mirror to receive the sun's rays reflected from the concave mirror, an opening in the concave mirror to receive a concentrated beam of the sun's rays reflected from the secondary reflector and to direct the beam along the mounting column, a third reflector movably located at the junction of the mounting column and the polar axis column to receive the concentrated beam of the sun's rays from the secondary reflector reflected through the opening, and to redirect it along the polar axis colu

  • Solar collector
    Patent number: 5195503
    Abstract: A solar collector for use in association with a building, the system having a concave mirror located on the exterior of the building and defining a focal point, a moveable mounting for moving the mirror to aim it directly at the sun at least over a predetermined period of the daylight hours, a secondary reflector located at the focal point of the concave mirror to receive the sun's rays reflected from the mirror means, an opening in the concave mirror to receive a concentrated beam of the sun's rays reflected from the secondary reflector, a third reflector located on the convex side of the concave mirror to receive the concentrated beam of the sun's rays from the secondary reflector reflected through the opening, and to redirect it along a heat storage path, a support connected to the concave mirror to receive the redirected beam, the support passing from the exterior to the interior of the building, an energy conversion system within the building interior to receive the redirected light beam from the mirror
