Abstract

Abstract 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, through means of intimately contacting pockets containing the objects being warmed.
