This invention relates to the efficient utilization of solar energy, to a practical level, for the warming or heating of objects such as golf balls and the like. The device is portable and comprises a clear, insulated cover, a black, conductive absorber plate and an insulated carrying base. Ultra-violet and visible light is admitted and trapped within the casing and is converted to infra-red by the absorber plate. The absorber plate conducts the heat generated, by the conversion to infra-red, th...

An apparatus for supporting and adjusting a solar oven with respect to the sun, the apparatus having a horizontally disposed main frame and a pair of vertical, spaced apart supports mounted to the main frame, the solar oven being pivotally mounted to the vertical supports; with means to lock the solar oven in a variety of positions with respect to the sun.

A solar oven or cooker for permanent installation as a kitchen appliance with provision made for collection of solar radiation throughout the daylight hours. Reflective panels are provided for coping with changes in the position of the sun, and with the different requirements of various cooking operations which reflective panels may be fixedly arranged or adjustably positioned by the operator.

A solar oven of improved efficiency wherein an octagonal radiation absorbing base is provided with eight primary reflectors and eight secondary reflectors to direct the solar energy thereupon. Each primary reflector is affixed to one side of the base at an angle of about 55.degree. thereto. The triangular secondary reflectors are interposed between adjacent primary reflectors at an angle of about 57.degree. to the base. The article to be heated is placed on the base and a transparent eight-sided...

A portable oven and grill heated by solar energy, which is fabricated of lightweight materials. The oven box is formed of a shaped open diagonal box, the walls of which are heat insulators, finished on their inner surfaces with a black matte surface to absorb radiated heat. Vanes formed of insulated panels coated on their upper sides with aluminum foil to reflect radiation are mounted along the top of each edge of the oven box and oriented at an obtuse angle to the vertical inner walls of the ov...

A demountable solar oven includes a principal base upon which is mounted a secondary supporting base collar which contains the essential operating parts and which supports two removable arms at their base whose upper end form diametrically opposed pivots for receiving the appropriately disposed pivots of the cooking chamber. The food basket provided with similarly diametrically opposed pivots is disposed interiorly of the cooking chamber and by virtue of a weight disposed at the bottom thereof t...

The invention is a solar heater which may function as a humidifier and which has a reflector that is constructed to provide a window, and external thermal insulation. The window has a cover that is positioned to transmit solar radiation to the reflector. The top portion of the reflector has an opening, and a container is removably positioned in the opening. The reflector has a geometry that reflects a high percentage of solar energy to the container, which has a surface with high absorptance. Th...

A portable concave reflector assembly having a hub member, a plurality of blade members radiating from the hub member, hub interlocking means for holding each of the blade members in selectively locked and secured relation with respect to the hub member, and blade interlocking means for holding each of the blade members in selectively locked and secured relation with respect to each adjacent one of the blade members. Each one of the blade members is identical in size and shape to each other one ...

A portable, solar powered golf ball warming device includes a hollow black tube as a warming chamber for golf balls. The black tube has separate elastomer loading and dispensing apertures disposed at opposite ends thereof. The black tube is disposed within a transparent housing which also supports a parabolic reflector shield. The parabolic reflector shield reflects solar energy to thereby warm the black tube. During sunny weather conditions, the device provides continuous heat to modern golf ba...

A central solar receiver comprising a housing with a frusto-conical window for the admission of incident concentrated solar radiation, a volumetric solar absorber within the housing surrounding the window, means for the injection of working fluid into contact with the volumetric solar absorber and means for the withdrawal of heated working fluid. The frusto-conical window makes the receiver suitable for operation at elevated pressure.
