ABSTRACT OF THE DISCLOSURE
The "ENERGY RADIATION REFLECTOR" is a reflective surface for the concentration of light and heat from the sun's radiation to a particular area. Its unique shape will accept incident rays from a large variety of solar zenith angles and reflect them into a focusing pattern of one long narrow straight line which falls mostly within the confines of the shape of the reflective surface and the encompassing enclosure into which it is mounted onto a heat and light receptor structure containing a circulating heat transfer medium, either liquid or gaseous.
This reflective surface is three dimensional and bent in its long horizontal plane in accordance with the following mathematical equation, in which "x" is the vertical axis and "y" is the horizontal axis, then, expressed by the following 8TH degree polinomial, with minor deviations:
y ? -(6.4550 x 10-13)x8 + (2.7799 x 10-10)x7 -(4.9542 x 10-8) x6 + (4.7343 x 10-6) x5 -(2.6403 x 10-4) x4 + (8.8896 x 10-3) x3 -(1.9194 x 10-1) x2 + (2.7232)x (2.1227 x 10-1).

SU~RY OF THE INVENTION
Our invention is a uniquely shaped reflective surface which will concentrate incident light and heat rays from a large variety of solar zenith angles along a long thin horizontal line within the confines of the reflective shape and the encompzssing enclosure into which it is mounted onto a heat and light receptor structure containing a circulating heat transfer medium either liquid or ~aseous.
For its primary purpose of concentration and collection of heat from solar energy the ends of the reflective shape are filled in vertically with a smooth insulated material with a reflective surface facing inward, also the front face of the main "energy radiation reflector" shall be covered with one or more sheets of transparent or translucent glass or plastic material, and a heat collection and transfer apparatus will be located along the horizontal line of maximum heat concen-tration. The heat collection and transfer medium may be either liquid or gaseous.
The "energy radiation reflector" may or may not, depending on circumstances, be augmented and amplified with an auxiliary reflective surface attached along the horizontal panel of the base or top of the reflective shape by hinges and capable of being tilted a variety of angles upward from the horizontal from O degrees to 90 degrees or until it completely covers th~
face.
1~37371 The "energy radiation reflector" may or may not, depending on circumstances, be augmented and amplified with auxiliary reflective surfaces attached along the front panels of the vertical ends of the reflective shape by hinges and capable of being opened and closed like doors through a variety of angles.
1~37371 BRIEF DESCRIPTION OF THE DRAWINGS
The objects and features of the invention may be understood with reference to the following detailed de-scription of an illustrative embodiment of the invention, taken together with the accompanying drawings in which:
F~G. 1 is a perspective view of the "energy radiation reflector" embodied as part of a solar heat energy collector with a variety of optional auxiliary reflective panels.
FIG. 2 is a plan view of the "energy radiation reflector"
embodied as part of a solar heat energy collector with a variety of optional auxiliary reflective panels.

FIG. 6 is a graph showing the axes upon which the descriptive mathematical equation is based which describes the "energy radiation reflector'!
DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning now descriptively to the drawings, in which similar reference characters denote similar elements through-out the several views, FIGS. 1-4 illustrate the "energy radiation reflector" (101) embodied in a solar heat collector in which a heat collection and transfer apparatus ~102) contai-ning a circulating heat transfer medium, either liquid or gaseous of any appropriate shape, size, design or material will be mounted on an approximately horizontal plane along the line of major reflected heat concentration as in (FIG. 5) on its top surface (103) and or on its bottom surface (104), or both surfaces at the same time.
The energy radiation reflector's (101) front surface (105) should be enclosed by one or more sheets of transparent or translucent glass or plastic to most efficiently allow for the maximum penetration of the surface by the shorter wavelengths of the heat spectrum and the least penetration of the surface, from the inside out, by the longer wavelengths of the heat spectrum to minimize the heat loss from the solar furnace.
The ends of the reflective shpae should be sealed with insulated upright end panels (106~ preferably mirrored on the inside surface.
The "energy radiation reflector", may or may not, depending on circumstances, be augmented and amplified with an auxiliary reflective panels (201) attached along the horizontal surface of the base or top of the energy radiation reflector by hinges (202) and capable of being tilted a variety of angles from the horizontal upwards until it covers the face (105) or, in the case of upper hinging, from the vertical position downward until it covers the face (105).
Similarly the "energy radiation reflector" may or may not, depending on circumstances, be augmented and amplified with auxiliary reflective panels (301) attached along the front surfaces of the vertical ends (106) by hinges (302) and capable of being opened and closed like doors, through a variety of angles until they cover the face (105).
In use at latitudes of 40 to 45 degrees N the reflective shape will accept and concentrate as in FIG. 5 most of the sunls rays between 30 - 60 degrees altitude measured upward from the horizontal (or 60 - 30 degree zenith angles) and when the horizontal Y
axis of the mirror (101), as designated in Figure 6, of the energy radiation reflector is elevated, on its concave side, above the horizontal position by 15 degrees it will accept and concentrate most of the sun's rays between 45 - 75 degrees altitude measured upward from the horizontal (or 45 to 15 degrees zenith angles). A 75 degree altitude is the maximum altitude of the sun at these latitudes at noon on June 21.
This one reflective shape therefore, with its two varieties of positions, accepts and focuses to a concentration area all the possible, significantly heat bearing, altitude angles of the sun for all seasons of the year. Sun altitudes of 30 ~3737~
degrees or less carry insignificant heating effect.
The following example is illustrative of the operation of the invention in use in fixed positions, which is the most economical use of this solar heat concentrator. It would ideally be used in units of 3 or multiples of 3 with one of them, or multiples thereof, facing approximately south easterly;
one, or multiples thereof, facing approximately south westerly;
and one, or multiples thereof, tilted backward at an angle of approximately 15 degrees above the horizontal, facing due south.
These angles will be changed slightly depending on whether the units are designed to maximize the heat absorption capacilities during the summer for heating swimming pools and by powering a heat exchanger to produce refrigeration effects sj or for the winter season for heating houses, or other habitable ` structures.
The shape of the reflective mirror of the energy radiation reflector (FIG. 6) is designated by the mathematical formula.
y = -(6.4550 x 10 13)x8 ~ (2.779~ x 10 ) x -(4.9542 x 10 8) ~6 ~ (4.7343 x 10 6) xS
