Abstract
Abstract A passive solar thermalization and thermal energy storage assembly which is visually transparent. The assembly consists of two substantial parallel, transparent wall members mounted in a rectangular support frame to form a liquid-tight chamber. A semitransparent thermalization plate is located in the chamber, substantially paralled to and about equidistant from the transparent wall members to thermalize solar radiation which is stored in a transparent thermal energy storage liquid which fills the chamber. A number of the devices, as modules, can be stacked together to construct a visually transparent, thermal storage wall for passive solar-heated buildings.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
A visually transparent, passive solar thermalization and thermal energy storage assembly comprising: a first transparent substantially planar wall member, a second transparent substantially planar wall member, the second member being substantially parallel to and spaced apart from the first member, a semi-transparent substantially planar thermalization plate located between the wall members and substantially parallel to both, sealing means between the first and second wall members for forming a liquid-tight chamber containing the thermalization plate, a transparent, thermal energy storage liquid in the chamber and means for preventing convective heat transfer within said liquid, said means for preventing convective heat transfer consisting of a plurality of visually transparent, horizontal accordian pleated baffles positioned between the thermalization plate and each wall member.
Claim 2
Dependent Claim
120 words
A visually transparent, passive solar thermalization and thermal energy storage assembly comprising: a first transparent substantially planar wall member, a second transparent substantially planar wall member, the second member being substantially parallel to and spaced apart from the first member, a semi-transparent substantially planar thermalization plate located between the wall members and substantially parallel to both, sealing means between the first and second wall members for forming a liquid-tight chamber containing the thermalization plate, a transparent, thermal energy storage liquid in the chamber and means for preventing convective heat transfer within said liquid, said means for preventing convective heat transfer consisting of a plurality of visually transparent, horizontal accordian pleated baffles positioned between the thermalization plate and each wall member.
Claim 3
Dependent Claim
17 words
The assembly of claim 1 wherein the wall members are mounted in a frame for structural support.
Claim 4
Dependent Claim
13 words

Claim 5
Dependent Claim
13 words
The assembly of claim 3 wherein the water contains a viscosity increasing agent.
Claim 6
Dependent Claim
128 words
A modular, visually transparent, passive solar thermalization and thermal energy storage assembly comprising: an open, rectangular-shaped support frame having substantially parallel first and second open sides, a first transparent wall member in the first open side, a second transparent wall member in the second open side, the two wall members together with the frame forming a liquid-tight chamber within the frame, a semitransparent thermalization plate in the chamber, the plate being parallel with and spaced about equidistant between the two walls, a transparent, thermal energy storage fluid within the chamber, and means for preventing convective heat transfer within said storage fluid, said means for preventing convective heat transfer consisting of a plurality of visually transparent, horizontal accordian pleated baffles positioned between the thermalization plate and each wall member.
