The reason behind paper's confinedness to use it for such purposes is primarily that other complex factors that plays role at macro-level is neglected here. Starting right from the requirement of the power output that needs to be procured to achieving the same, each and every point is discussed here in this paper.

There must be a revolutionary way to make solar power into something that is available to everyone and anyone throughout the world. The [1]Solar Updraft Tower (SUT) technology generates renewable energy by sun-wind energy harvesting. In SUT the solar radiation, which is an inexhaustible input, is converted into electrical power through the natural updraft of heated air in a very high chimney. The main problem in traditional SUTs is that they require substantial region of greenhouses and a large updraft of air in the chimney to obtain the desired outputs, which is nearly impossible to achieve with domestic models used for educational purposes this could be tackled by the proposed invention. 1.1 BASIC PARTS OF SOLAR UPDRAFT TOWER The solar updraft tower’s three essential elements – solar air collector, chimney/tower, and wind turbines. Solar Collector- Hot air for the solar tower is produced by the greenhouse effect in a simple air collector consisting of a glass or plastic glazing stretched horizontally several meters above the ground. The height of the glazing increases adjacent to the tower base, so that the air is diverted to vertical movement with minimum friction loss. This glazing admits the solar radiation component and retains long-wave re-radiation from the heated ground[2]. Solar/Chimney Tower- The tower itself is the plant's actual thermal engine. It is a pressure tube with low friction loss (like a hydro power station pressure tube or pen stock) because of its favorable surface-volume ratio. The updraft velocity of the air is approximately proportional to the air temperature rise (∆T) in the collector and to the tower height. Turbines- Using turbines, mechanical output in the form of rotational energy can be derived from the air current in the tower. Turbines in a solar tower do not work with staged velocity like free-running wind energy converters, but as shrouded pressure-staged wind turbo generators, in which, similarly to a hydroelectric power station, static pressure is converted to rotational energy using cased turbines[3]. The SUT is a design concept for a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a hot air updraft in the tower by the chimney effect[4]. This airflow drives wind turbines, placed in the chimney updraft or around the chimney base, to produce electricity. 1.2 DESIGN PARAMETERS FOR ANALYSIS The given flow chart shows us the complete selection procedure of a SUT for educational purposes, To begin with the primary process is selecting the power output for tower, which is as per the need of one. After that it requires to presume any one of the following parameters, either it be radius of the solar collector or the height of the chimney tower.
