ABSTRACT:
A passive solar heating system in which an opaque black-dye solution of water and alcohol circulates through a flat tapered spreading chamber and through a series of seven parallel conical flow tubes. The spreading chamber and the flow tubes are clear glass, and this permits the direct absorption of radiant heat into the water. A flow tube is an elongated glass tube composed of multiple conical sections. The direction of flow is from the small end of the conical section to the large end. The heated water expands outward against the tapered wall of the conical section and deflects in the direction of flow, thereby increasing the rate of flow.
