How to Make a Solar Oven at Home
A solar oven is a great to cook off the grid and are easy to make on your own. Not difficult to make and your family will enjoy the fresh and hot meal. It takes about 30 minutes for a solar oven to preheat.
TO MAKE YOU NEED:
· two cardboard boxes (one large and one smaller)
· black construction paper
· scissors
· aluminum foil
· glue and tape
· staplers
· old newspapers
· a pencil (or a marker)
· plastic wrap.
- First, line the bottom of the large box with well crumbled newspaper. Then, insert the smaller box into the larger one, and fill in the empty side spaces between the boxes with newspaper crumbles.
- Make sure to cover the inside walls of the small box with aluminum foil. You can use invisible tape to glue the edges of the aluminum foil to the edges of the cardboard box.
- Glue the black construction paper onto the bottom of the small box. This will help absorb the heat much better, and your homemade solar oven will be more efficient.
- Next, on top of the large box, you need to lay a large piece of cardboard. Now trace the shape of the box on the board nicely, using a marker. Allow around 2-3 inches on each side around the trace line, and cut the cardboard.
- Now use aluminum foil in order to cover the cardboard. The aluminum foil that is placed over the cardboard must be extremely smooth and without any wrinkles so that it will reflect the light properly. Use invisible tape or glue in order to secure the aluminum foil onto the cardboard. The reflector that you obtained this way should be stapled or glued to the back of the large box.
Now your homemade solar oven is ready, and you need to make sure to place it so that the reflective part is facing the sun directly, for maximum efficiency. You can place just about any type of pot with a glass top that fits into your oven, and start making food using solar energy. You need to be patient however, because it might take even up to 3 or 4 hours until your meal is ready, so make sure to start cooking earlier than usual. If you want to make your cooker even more efficient, place a plastic wrap on top of your oven. Keeps the heat in a lot better with the plastic wrap over it.
