An experimental model of a wind solar chimney for electrical supply was developed, firstly, the most suitable geographic space was selected for the implementation of the model. Next, we carried out a study in order to determine the environmental, wind and solar parameters using the viewers of the Ministry of Energy and Mines; Taking renewable energy resources as a starting point, a pre-dimensioning was established in order to guarantee economic and technical viability to be able to build the model.The theory of similarity was applied to define the preliminary geometry of the chimney considering built plants as referents, marking the difference of adding two additional subsystems, one wind and the other photovoltaic in order to give it greater autonomy; the wind subsystem located in the upper part of the chimney and the photovoltaic subsystem along the outer surface of the chimney collect...
