How To Make A Solar Oven

A solar oven can be used to cook anything that can be cooked in a conventional oven. If you have ever wanted to make your very own solar oven, then follow these simple steps and your solar oven will be up and running in no time.
Things Required 
  • Aluminum foil
  • Cardboard
  • Large and small cardboard boxes
  • Non-toxic glues
  • Non-toxic invisible tape
  • Plastic wrap
  • Scissors
  • Newspaper
  • Pencils
  • Black construction paper
  • Staplers 
Making A Solar Oven 
  • First of all, you will need to find two boxes. The boxes should be such that one should fit comfortably inside another with a 2 to 3 inch space on each side. However, this 2-3 inch space is not a rule of thumb. This space is required to be filled with newspapers.
  • Now, stuff the bottom of the smaller box with newspapers.
  • Next, use some crumpled newspapers to fill the space that is there between the two boxes.
  • Use some aluminum foil to fill in the sides of the inside of the smaller box. Use some sort of non toxic adhesive or tape so that the top of the box holds it in place nicely.
  • Use black paper to line the bottom of the smaller box so that it will help in absorbing the heat.
  • You will need a big piece of cardboard to lay it on to the top of the big box. Now, add 2 inches around the outside box and cut it out. This will act as a reflector.
  • The next step involves covering the cardboard piece with aluminum foil. Make sure that any kind of empty space or wrinkles are properly handled. Use some sort of non-toxic glue or adhesive tape to do the work cleanly.
  • The oven needs to trap heat into it; hence you will need to staple the reflector on to the outside back of the larger box.
  • Make sure that the reflector is facing the sun. This will help the oven in trapping maximum heat.
  • Try out your new oven by placing food which needs to be cooked inside the oven. After placing the food item inside, cover the oven with a clear plastic wrap so that the heat that is trapped is actually used to cook the food item. 

However, please note that though you can cook any food item using a solar oven, the cooking time would be almost twice that of a conventional oven. The pre-heating alone of a solar oven takes about 30 minutes.
