Abstract
The energy by Helio-aero-gravity action can be produced by choosing a plane area of land in a desert where solar radiation is bountiful. The land is covered with some diaphanous material. A solar chimney enclosing an air turbine is to be placed at the center of canopied land. At the boundary of the patch, the canopy should be kept above the ground allowing ample space for the entrance of air. The flat patch of land is heated by direct solar radiations entering through diaphanous cover. When air moves over the heated land surface it gets heated. As a result of pressure difference, the heated air will rise in the chimney and drive the turbine. The Helio-aero plant, in which the height and diameter of the chimney are 200 m and 10 m, respectively, and the diameter of the solar collector cover is 500 m, can produce 110 to 190 kW electric powers all year. Some parameters, like ambient temperature, height of chimney, diameter of collector, solar irradiance and the efficiency of turbine, etc. which affect the performance of power generation, are analyzed.
