Solar Cooker: Design, Construction and Performance

The main objective is to replace old usage of firewood as a source of fuel for cooking especially in the villages. According to a survey, each family utilizes two fully grown up trees in a year. Our design of solar cooking is strictly based on cost efficiency, easy availability and workability. The geometry of the cooker includes simplest form of an angled panel surrounded by reflectors for enhanced efficiency. The cooker surrounded by insulating card board box with material which when heated retains heat so that it can be used when sun is low.
