Essay On Solar Cooker

INTRODUCTION
Food is necessary for living organisms but in developing countries it can be limited. Many people cook their food in open fire atmosphere and used mostly fuels for cooking purpose. In fuels, wood is used, which is expensive and due to use of wood climate change (Metcalf, Bob. 2004).
About 94% of African rural Population, and almost 73% urban population used wood as fuel for their primary use, according to statistics of World Bank (Melanic, 2006). Solar cooker is very useful use in many sunny parts of the world (Nandwani 1992, Devadas 1992 and 1997, Olusegun 2006). The concept of solar cooker technology is not new. Most work have been done over the years (Lof 1965, Wary 1992, Warren 1994).
Using special geographical locations, under particular environment and physical aspects, various types of solar cooker have been observed (Malik et al., 1996, Adegoke et al., 1998).
In various versions, box solar cooker is one of the most

(2011) summarized the efficiency of solar box cooker of about 96% by using low rate and easily available material. The experiments responced about 72C temperature for both at the roof’s top and at the ground floor having 38c and 35c air temperature. By decreasing difference of temperature between ambient and collector temperature efficiency can be inhanced. Reducing solar radiations efficiency may also reduced. Omotoyosi et al. (2017) described that due to energy and electricity crisis, solar cookers have achieved the attention. Some of solar cookers either exposed the cooking section either direct to the sun or indirectly exposing to sunshine. To overcome the solar cooker’s problems, parabolic reflectors has been used to heat the expected material in a frustum like receiver. The cooker having insulating energy storage separated from dish and cavity system. Sooler cooker with 39% of utilization energy,0.05% overall energy and 13 minutes/kg calculated characteristic boiling
