Engineering, design and fabrication of a solar cooker with parabolic concentrator for heating, drying and cooking purposes

摘要

Indian subcontinent is blessed with ample amount of sunlight almost all through the year. Roughly 80% of all seasons are sunny of which 50% is dry and hottest. There is urgent need of switching over to a perennial source of energy reserve as a powerful alternative so as to replace all the fastly depleting fossil fuels. There is much interest in non conventional energy nowadays so as to tap energy from unassuming but promising quarters such as Solar, Wind and Tidal energy. Of which, tapping the heat and infra-red rays from the sun using air and water as appropriate mediums, separately and together as a whole is the most easiest and versatile way of energy capture. In order to tap this abundant energy we require an efficient design of a solar concentrator which heats up the ambient in the quickest pace. A cost effective solar concentrator is made with locally available raw materials which is efficient enough to make water reach steam point and air reach its hottest phase. A thorough dealing with a span of six months observation on the working of the solar cooker is presented in detail.
