Abstract: My invention relates to a unique apparatus for the utilization of solar heat which incorporates a hexagonal shaped collector element, which achieves maximum heat utilization in conjunction with a heat pipe for transfer of the heat collected by the element. Various minor modifications can be made to the heat collector element and/or the heat transfer pipe without departing from the spirit or the scope of the invention. Basically, however, it is the hexagonal shaped heat collector element with the heat transfer pipe passing therethrough at substantially the optimum position so that maximum heat transfer occurs from the heat collector element to the pipe within each individual element. The entire apparatus can be adjusted for optimum sun angle, depending upon the hemisphere or latitude of use, and extremely efficient heat transfer and use of solar energy is possible.
