Design and Fabrication of Double Angled Eight Sided Solar Cooker

Abstract

Given the prevalent energy crises across the globe, it is always desired to exploit new and renewable energy sources which are readily available at almost negligible cost..  Solar cookers have come in various forms: parabolic cookers, panel cookers, box cookers, and funnel cookers; each with its own design and performance peculiarities. In this project double angled eight sided solar cooker was designed, fabricated and tested. Chrome plated steel whose reflectivity of 85%was used as reflective surface to increase temperature and heat required to cooking. The test results shown that maximum of upto95 ⁰C temperature can be achieved without changing the position of solar dishand also it is possible to achieve heating power of 1981.2Wattin 10 min, required for cooking any kind of vegetables.The maximum efficiency of this solar cooker is 211% for 10 min time span.
