Abstract
Today, due to the increase in cost of living, people are finding alternate means to generate energy. Non-conventional sources of energy such as solar, wind and geothermal energy are being harnessed to meet the increase in demand and cost. As we live in a tropical region, solar energy is reliable and available in abundance.
A solar cooker is a simple device that utilizes the heat energy obtained in form of thermal radiation form sun to cooks the food, boils water and also can be used for sterilizing instruments. Solar cooker has seen its existence as late as 1700’s. Solar cooker has seen its dominance mainly in developing and emerging countries especially in India.
In order to overcome the issues with the existing solar cooker technology, we have developed a prototype to elevate the temperature, thereby increasing the heating efficiency within the cooking chamber. Cooking chamber is enclose within a glass box expect for the side available to be opened to place food/water inside the container. The glass box and cooking chamber are well sealed so as to not allow the carbon dioxide into the cooking space. A small opening is provide in the glass box fitted with a cork, which acts as an inlet and outlet port to allow the space within the glass box to be filled with carbon dioxide. Cooking takes place in a solar box cooker based on the principle, the black absorbing material coated inside the walls of the cooking chamber absorbs direct thermal radiation from the sun converting it to heat energy. In general, sunlight both direct and reflected enters the solar box through the glass, the entered light is scattered by the green house gases mainly water vapour present within the container who’s wavelength increases. It turns to heat energy when it is absorbed by the dark absorber plate and cooking pots. This heat input causes the temperature inside of the solar box cooker to rise until the heat loss of the cooker is equal to the solar heat gain. Temperature obtained is sufficient to cook food and pasteurize water.
