Solar Cooking
For Solar cooking I would recommend is the box type. Although this might not be the best to cook food it is definitely the cheapest. Did you know that some people in other countries live off only $2 a day. The box cooker can be transported easily. This cooker also is the easiest to build. All you need is some aluminum foil an old shoe box or any other box. You can take some black spray paint and spray the inside to conduct heat. This would be the best in other countrys because it is easy to use. All you do is put the food inside the dark box put a piece of ceran rap over the top so that heat does not escape. This is my recomendation on solar cookers.
