Diseño de un sistema sostenible de generación de energía, aprovechando el efecto piezoeléctrico en la PUJ Cali

Abstract

The present project seeks to design a sustainable energy generation system taking advantage of the piezoelectric effect that mitigates the environmental impact and the costs of current energy sources from the university in Colombia. This idea arises from the opportunity identified in the institution to use human movement as a source of energy due to the great flow of people on campus. The method was based in the anthropometrical and biomechanical characterization of the population in order to quantify the potential energy that could be obtained through the movement of people when they activate the piezoelectric product located and distributed in the place that will be identified as the area with the greatest possibility of energy generation. All of this making use of tools of industrial engineering like, methods, Plant layout, schedule and others. The tiles used in the design are composed of 80% recyclable materials, which indicates that it is a product friendly to the environment. The environmental analysis was made based on the CO2 emission factor per kWh-generated of the Colombian interconnected electricity system, which is 0.199 kg of CO2 per kWh produced. If the piezoelectric tiles are installed as indicated by the final configuration in the main traffic path obtained in the analysis of this project, a saving of 84.478 kg of CO2 could be achieved in the case of producing the minimum energy which is 424.517 kWh and a saving of 169.133 kg of CO2 in the case of producing the maximum energy corresponding to 849.913 kWh. With the decrease in CO2 emissions that result from the implementation of the tiles, the high environmental impact of the project is concluded because it contributes to the reduction of the emission of greenhouse gases caused by the energy consumption of the participating institution.
