Because of the threat of climate change, many people now look for clean alternatives to conventional sources of energy. The energy that the sun provides, for example, is gaining in popularity because it is renewable and environmentally friendly. It doesn't even have to b expensive to make the switch, since you can build an effective Solar Oven at home.
Not only is a cooker that uses the sun's heat a cheap alternative that saves electricity, but it also provides a solution for making a warm meal when you don't have access to other types of energy. In many developing countries, it can even prevent water-borne diseases because it enables people to boil water and make it potable. In addition, it's very easy to make your own cooker.
Making your own cooker is so easy that even a child can do it. You will need a cardboard box big enough to accommodate a pie tin or pot. You'll also need some aluminum foil, black construction paper, old newspapers, clear plastic wrap, and tape or glue. The tools to have on hand include scissors or a box cutter as well as a ruler, stick or wooden spoon about a foot in length.
The first step is to cut the top of the cardboard box to make a flap. Draw a straight line at least an inch from the edge, on three sides along the top. Cut along this line and lift the flap.
Next, you need to apply aluminum foil on the inside of the flap. Smooth it out as much as possible and secure it with glue or tape. The reason for the aluminum foil is to have something that will reflect rays from the sun so that they enter the box.
Black is good at absorbing heat, so use the black construction paper for lining the bottom of your cardboard box. You also need to insulate the oven to keep the heat inside. For this, you can roll up sheets of newspaper and place them all along the sides.
The best time to use your oven is around midday, when the sun shines at its brightest. Place the box in a sunny spot and place a pie tin, plate or pot with food inside. Then tightly tape two layers of clear plastic wrap over the opening in the box, since this will allow the heat to enter but not to escape again. Using a ruler, stick or wooden spoon, prop up the lid at an angle that best reflects the sunlight into the box.
Your cooker will take more time to heat up than a regular one. It is most effective for food that needs slow cooking, like stew, soup, rice or baked spuds. However, the inside can reach sufficiently high temperatures for cooking egg dishes, melting the cheese on nachos or sandwiches, baking cookies or even boiling water for tea or coffee. The trick is to check the angle of the flap throughout the process and adjust it from time to time, ensuring that it directs the rays of energy down into your homemade cooker.
