Solar Oven

Harness the "free" energy from the sun and use a solar oven to cook your food. These ovens are easy on the environment, cost effective, and highly portable. Cooking with solar heat preserves the nutrients in food and reduces the risk of foodborne illnesses. In many of the less developed countries in the world, solar cooking has long been a primary cooking method. In areas where electricity is not readily available or affordable, it is often the only alternative to cooking over wood fires.

Whether you are looking to buy an oven or make your own, they are great for camping, traveling, and picnics. Solar cookers are an excellent alternative to conventional cooking methods.

Materials

  • Cardboard pizza box
  • Ruler
  • Scissors
  • Aluminum foil
  • Clear tape
  • Heavy-duty freezer bag
  • Black construction paper
  • Newspaper
  • Wooden spoon

Instructions

  1. Draw a square on the lid of the pizza box that is 1 inch smaller than the box on all sides.
  2. Cut three sides of the square to make a flap.
  3. Fold the flap so that it stands up when the lid is closed.
  4. Cover the inside of the flap with aluminum foil, using tape to secure it to the cardboard.
  5. Cut the freezer bag open along the seams.
  6. Open the box lid and tape the freezer bag to the inside of the flap hole. This will create an airtight window for sunlight to enter the box.
  7. Put black construction paper on the inside of the bottom of the box.
  8. Roll up several sheets of newspaper and tape them around the inside of the box bottom. Be sure that the lid can still close.

Directions for Use

  • Use the oven between the hours of 11 a.m. and 3 p.m. when the sun is highest.
  • Adjust the flap until as much sunlight as possible is reflecting off of the foil to the window area.
  • Use a ruler to keep the flap open at a right angle.
  • Try buttering a slice of bread and placing cheese on top. Cook the bread in the oven on a clear glass or plastic plate.
  • Be careful when taking the plate out of the oven; it will be hot.

  4. Center the small box on top of the scrap fabric.
  5. Fill the spaces between the two boxes with more scrap fabric.
  6. Cut a piece of aluminum sheeting 1 to 2 inches wide and nail it from the inside lip of the small box to the far top side of the large box to form a rim covering the insulating material.
  7. Place a sheet of Plexiglas over top of the cooker.
  8. Use dark cookware for best results.
