Design and Development of Portable Solar Parabolic Cooker with Inorganic PCM Storage

Abstract

This paper, an experimental investigation is carried on a solar cooker with heat storage. Solar cookers are passive solar devices, which converts sunlight into to heat energy which is retained for boiling. Solar boilers use the cinch principle of mirror image application, green house effect and absorption to convert sunlight to heat energy. The steps involved in the solar boiler concentrating capturing and converting the PV energy. It is a clean cooking technology without any carbon emission. The main challenges of solar cooker are economically not viable, incompatible with traditional cooking, direct sun cooking, off solar boiling, risk of getting parched. The PCM material used here is Mg(NO3)2.6H20. The mentioned challenges have been resolved in proposed design
