The process illustrates how a solar box oven cooks food. This can be oultined in a number of consecutive steps. Overall, there are six steps tothe process starting with preparing the box and ending with cooking food. Moreover, the process is a simple one which requires not much time and equipment. This is man-made process.
The first stage is rather simple: cardboard box which is painted to black. Once painted, vegetables and other ingridients are put inside the pot. Then, this pot is placed into that cardboard box.
The next stage begins with preparing larger box where it has newspaper, grass, or sawdust at the bottom of that large box. After doing this, the box is placed into a larger box.
The following stage involves covering the top of the larger box with foil. And on the top of the foil is put glass lid. The final step is rather difficult: the entire setup shoul be placed under direct sunlight. The temperature should be minimum 82 Celsius degree. When the black color absorbs light and converts it into heat, this process cooks the food.
