The diagram presented elucidates the sequential process involved in preparing a meal using a solar box oven.
This method encompasses six distinct stages, each contributing to the efficient harnessing of solar energy for cooking.
The initial step necessitates coating the cardboard box with a black paint, which enhances its ability to absorb sunlight effectively. Following this, a pot containing vegetables is placed within the painted cardboard box. Subsequently, the container is secured inside the black cardboard structure, thereby optimally positioning it for solar energy absorption.
The fourth phase involves placing the black box into a larger box, where insulating materials such as newspaper, grass, or sawdust are positioned at the bottom to trap heat. The larger box is then sealed with a foil cover and a glass lid to create a greenhouse effect. Finally, the entire assembly must be exposed to direct sunlight, ensuring that the temperature reaches a minimum of 82°C. The black color of the box facilitates the absorption of light, which is converted into heat, enabling the cooking of the food inside the pot.
