A solar heat collecting dome includes a frame having an odd number of frame elements extending upward and inward from a floor structure to a disk at the top of the dome. A dome shaped helical structure including two flexible tubes is woven to extend along and around the frame elements, with the dome shaped helical structure extending across alternating inner and outer sides of the frame elements, and with adjacent portions of the dome shaped helical structure extending across alternating inner and outer sides of each frame element. At an outer end of the dome shaped helical structure, the two tubes form an inlet and an outlet. At the inner end, the two tubes are joined. The frame may also include a fluid path, with the fluid moving in opposite directions in each of the frame elements.
