Abstract
Abstract A method and apparatus for collecting, intensifying and storing solar energy which includes a hollow spherical vessel 10 having a polished reflective interior surface. A window 32 is provided in the wall of the vessel for allowing concentrated rays from the sun to enter into the interior of the vessel and be absorbed by a solar collector 20. The collector includes a substantially black (or a selective coating) heat absorbing surface carried by a spherical member 16 which is centrally located within the spherical vessel. Heat absorbing media 18 such as metal shots are carried within the spherical member and change from a solid state to a liquid state as it absorbs the solar energy. The heat absorbing media 18 cause radiant energy to be radiated radially in a symmetric beam pattern to the reflective vessel wall where the radiation is reflected back to the spherical member 16. The reflected radiant energy, in conjunction with the sun's rays, intensify the temperature of the heat absorbing media, producing a thermal power supply.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
An apparatus for collecting, intensifying or sustaining, and storing solar energy comprising: a hollow vessel having an interior wall; a window provided in said wall of said vessel for allowing concentrated rays from the sun to enter into the interior of said vessel; a solar collector carried adjacent the center of said vessel spaced from the interior walls of said vessel, said solar collector including; (i) a container, (ii) a substantially black fluid heat absorbing surface positioned for being contacted by said rays passing through said window, (iii) heat absorbing means carried in said container supporting said substantially black fluid heat absorbing surface for absorbing and storing thermal energy from said heat absorbing surface and for heating said container causing radiant energy to be emitted from said container, and (iv) said heat absorbing means being metal that goes from a solid state to a liquid state upon absorbing thermal energy from said substantially black heat absorbing surface, and a polished reflective surface carried on an interior wall of said vessel for reflecting radiant energy back to said container intensifying the temperature of said heat absorbing means.
Claim 2
Independent Claim
186 words
An apparatus for collecting, intensifying or sustaining, and storing solar energy comprising: a hollow vessel having an interior wall; a window provided in said wall of said vessel for allowing concentrated rays from the sun to enter into the interior of said vessel; a solar collector carried adjacent the center of said vessel spaced from the interior walls of said vessel, said solar collector including; (i) a container, (ii) a substantially black fluid heat absorbing surface positioned for being contacted by said rays passing through said window, (iii) heat absorbing means carried in said container supporting said substantially black fluid heat absorbing surface for absorbing and storing thermal energy from said heat absorbing surface and for heating said container causing radiant energy to be emitted from said container, and (iv) said heat absorbing means being metal that goes from a solid state to a liquid state upon absorbing thermal energy from said substantially black heat absorbing surface, and a polished reflective surface carried on an interior wall of said vessel for reflecting radiant energy back to said container intensifying the temperature of said heat absorbing means.
Claim 3
Dependent Claim
40 words
The apparatus as set forth in claim 1 further comprising: a radiant exchanger spaced from said container, means positioned between said radiant exchanger and said container for controlling the transfer of radiant energy from said container to said radiant exchanger.
Claim 4
Dependent Claim
36 words
The apparatus as set forth in claim 2 further comprising: a housing wall being spaced from and enclosing said hollow vessel, and thermal insulation carried between said housing wall and said vessel providing an insulating layer.
Claim 5
Dependent Claim
18 words
The apparatus as set forth in claim 3 further comprising: said layer of thermal insulation being diatomaceous earth.
Claim 6
Dependent Claim
30 words
The apparatus as set forth in claim 2 further comprising: said means for controlling the transfer of radiant energy from said container to said radiant exchanger including an adjustable door.
Claim 7
Dependent Claim
30 words
The apparatus as set forth in claim 5 further comprising: said adjustable door including, (i) a plurality of hinged doors; and (ii) means for selectively opening and closing said doors.
Claim 8
Dependent Claim
