GR1004837B - Wall construction for floating solar chimneys (fsc) - Google Patents

Abstract

floating solar chimney susceptible to measure some kilometres in height is disclosed herein. It can be demonstrated that the maximum operational sub-pressure exerted on the wall of the FSC is almost analogous to its height so that chimneys of great height are able to receive very high sub-pressures. For constructional reasons, it is preferable to separate the wall of the FSC from its suspension rings-balloons; this is realizable by the two constructions described hereinafter: At the first construction (fig. 1), the wall is formed by rings-balloons of small local curvature (1.1) full either with lifting gas (He or NH3), or simply with environmental air easily getting in and out therefrom. The wall is supported by the support rings 1,2 placed between the rings of the wall made of A1 or composite material of sufficient cross section for facing the strong forces of the operational sub-pressure. The suspension of the FSC is assured by external rings-balloons 1.3 of sufficiently great cross section. The external rings-balloons are attached to the support rings. At the second construction (fig. 2), the wall FSC is of simple sheet of resistant fabric 2.1 used in balloons 2.1, or airships with thermal insulation or not. The operational sub-pressure on the wall FSC is faced with the aid of support rings 2.2 made from A1 or composite material of sufficient cross-section. The successively arranged support rings are interlinked with strong threads 2.5. The distance from one to another is smaller than the height of the wall fabric encountered between them so that the fabric can form a small radius curvature for facing the operational sub-pressure exerted thereon. The suspension of the FSC is ensured by external rings-balloons 2.3 as in the foregoing construction. The bending of the FSC by external winds is guaranteed with the help of a system composed of a bipartite heavy base and a flexible accordion-type lower section (fig.3).
