Abstract
Abstract A solar heat wave energy system having a solar energy collector that collects energy from the sun to heat a boiler which in turn runs a steam turbine generator for generating electricity during the daytime. The system also has an assembly for generating electricity during the nighttime, which assembly includes a storage structure disposed between the solar collector and the boiler. This storage structure includes a plurality of separate storage stacks, each housed underground and including a plurality of heat conductive pipes interdigitally arranged with a plurality of plates constructed from twice-baked clay and arranged resting on a base formed from a similar clay as the plates. Solar energy is absorbed by the collector and transferred to the storage structure by means of suitable piping for storage in the twice-baked clay plates. When the stored heat is to be later used, as in the nighttime or on overcast days, a switching device uncouples the collector from the storage structure and couples the storage structure to the boiler.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
An energy conversion system, comprising, in combination: (a) first and second collector means for collecting radiation from a source of radiation, each of the first and second collector means including a pipe arrangement containing a fluid to be heated; (b) support means for selectively moving the first and second collector means along a predetermined path of movement; (c) power generating means for converting into useful energy the thermal power collected by the first and second collector means; and (d) station means disposed along the predetermined path of movement for selectively coupling the pipe arrangement of each of the first and second collector means to the power generating means.
Claim 2
Dependent Claim
108 words
An energy conversion system, comprising, in combination: (a) first and second collector means for collecting radiation from a source of radiation, each of the first and second collector means including a pipe arrangement containing a fluid to be heated; (b) support means for selectively moving the first and second collector means along a predetermined path of movement; (c) power generating means for converting into useful energy the thermal power collected by the first and second collector means; and (d) station means disposed along the predetermined path of movement for selectively coupling the pipe arrangement of each of the first and second collector means to the power generating means.
Claim 3
Dependent Claim
64 words
A structure as defined in claim 1, further including heat storage means comprising a plurality of heat absorbent plates formed from twice-baked clay, and coupling means connected to the heat storage means and the first and second collector means for carrying heat to the storage means during periods when radiation from the source of radiation is impinging on the first and second collector means.
Claim 4
Dependent Claim
61 words
A structure as defined in claim 2, wherein the heat storage means includes control means for preventing conveyance of heat from the heat storage means to the power generating means during periods when radiation is impinging on the first and second collector means, and permitting conveyance of heat from the heat storage means to the power generating means at other times.
Claim 5
Dependent Claim
49 words
A structure as defined in claim 3, wherein the power generating means includes first and second generating assemblies, the first of these generating assemblies being connected directly to the first and second collector means, and the second of these generator assemblies being connected directly to the heat storage means.
Claim 6
Dependent Claim
38 words
A structure as defined in claim 2, wherein the heat storage means includes a plurality of pipe sections disposed between the twice-baked clay plates for transferring heat between a fluid contained in the pipe sections and the plates.
Claim 7
Dependent Claim
70 words
A structure as defined in claim 5, wherein the heat storage means further includes a top plate and a bottom plate both formed from twice-baked clay and each having a plurality of spaced flanges extending perpendicularly therefrom, the plates being spaced beneath and above the plurality of stacked plates, with the flanges extending between adjacent ones of the stacked plates in order to space the stacked plates from one another.
Claim 8
Dependent Claim
38 words
A structure as defined in claim 6, further including a concrete housing for containing the plates, the housing being covered by a layer of asphalt and by earth such that the heat storage means is contained totally underground.
Claim 9
Dependent Claim
24 words
A structure as set forth in claim 1, wherein the support means includes drive means for independently moving the first and second collector means.
