Solar oven on 'Stand-by'.
This cost me less than $2 to make. Everything used to make the solar oven were items for the recycling bin. Tin Foil was the only item I needed to purchase.
What you need:
One large box.
One smaller box (they can be either wood or cardboard).
Any insulation material (this can be polystyrene, straw, news papers, cloth, tee-shirt material, blanket).
Tin foil or reflective silver material.
Sheet of glass (glass pieces from a clip frame at Ikea have bevelled edges). If broken glass is used in an emergency situation, try and tape the edges with masking tape to avoid injury.

Mirror (if you've got one).
I put in a small cooking rack to elevate the containers (increases the surface area exposed to solar energy). A brick (which retains heat) or a few flat stones will do the same. This will be useful in windy weather.
Instructions to make solar oven:
Line larger box with insulation material (in this case polystyrene and straw).
Place the second box inside the large box.
Line the container with tinfoil or silver reflective paper.
Tape the edges box flaps (also covered in foil) together so they also act as energy selectors and gives you a deeper box.
You can lean a mirror against the box, directing light in but care must be taken to place solar oven onto brick, stone or sand to avoid an accidental fire.
Place a metal rack inside to elevate food containers.Oven is now ready to place in a sunny spot.
Cooking containers suitable for solar cooking:
Dark glass containers.
Pyrex containers with lids.
Pyrex bowls with sealed plastic bag to cover.
Metal containers with glass lids.
Glass preserving jars with lids.
Glass microwave containers with lids.
