Abstract
Abstract An array of several convection tubes are positioned in a series configuration to provide the equivalent of a very tall convection current generating tower, the pressure and fluid flow of the array thereby becoming capable of significant pressures such as the pressures necessary to move solar heated air into the confines of a rock storage area, the pressure increases of this array being achieved by the additive effects of connecting heated and cooled convecting columns together alternately in such a way that the output of one is connected to the input of another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
A passive solar energy operated system comprising: a multiple convection current production means comprising an array of several elongated cavities forming convection columns said convecting columns being of a twofold variety the one type producing convection fluid movement by means of heating and the other producing convecting fluid movement by means of cooling and an alternate tube connection means coupling the output fluid of a heating covection tube to the input duct of a cooling convection tube and connecting the output end of a cooling convection column to the input of yet another subsequent heating tube and so on providing a series of connected alternate heating and cooling convection tubes so interconnected that the convection action of each tube adds to the convective flow produced by the others and, convection tube heating providing a temperature rise for the alternate tubes that produce convection current by heating and, convection tube cooling means providing a temperature decline for those alternate tubes causing convection current by cooling wherein the convection tube heating means is a solar collector.

Claim 3
Dependent Claim
26 words
A pump as in claim 1 in which the heating means is a solar energy storage unit into which the heating convection tubes have been placed.
Claim 4
Dependent Claim
21 words
A pump as in claim 1 in which the convection tubes or cavities are cylinders placed into solar energy absorbtion collectors.
