The diagram shows the process of the solar box oven and how it used to cook food using sunlight.
Overall, the procedure includes five main stages, beginning with preparing the cardboard container and ending with heating the food under sunlight. The process relies entirely on solar energy, converting light into heat through the easy structure.
To begin with, a cardboard box is painted black allowing it to absorb heat more effectively. Following this, vegetables are placed inside a pot, which is then inserted into the black box. At the next stage, the smaller box containing the pot is positioned inside a large box. This outer container is lined with insulating materials such as newspaper, grass or sawdust, and then the top is covered with foil before a glass lid is placed on it to prevent heat from escaping. Finally, the finished solar oven is placed outdoors under direct sunlight where temperatures must reach at least 82°C.
