Night Cooking Solar Cooker Using Molten Sodium Chloride as Phase Change Material, 2013.
O Parida, et al.
Solar cooking technology has to undergo a sea change if at all it’s to be accepted as the main source of cooking Energy. This is why a better model that incorporates both the traditional heat trapping cum concentrator mechanism and the latest techniques like that which uses a solar battery (phase change materials with high heat retention capability) can be used as the basic idea for the purpose.
A multi-purpose hybrid solar cooker using locally available materials can be used for night as well as day cooking. It will have two way supply of heat directly from sun during day time for cooking and from the phase change material during night time. This cooker preferably provides indoor cooking and it can have two arrangements, namely Grill and Oven, for cooking various Indian foods.
Sufficient care was taken for selecting the materials to be used in this solar cooker with price and availability
constraints across rural India. The design ideally can cook two traditional meals a day for a family of five. All assumptions for the design are based on this basic aim.
