Build a Solar Cooker
|
Insulated Box
1. Draw the outline of the reflector segment and cut the 4 cardboard segments.
2. Spread the glue evenly over the cardboard segments and cover them with Aluminum foil with the shiny side up. Avoid wrinkles and creases as this would decrease the efficiency of the reflector.
3. Arrange the panels keeping a 2mm space between them as shown above. The wide sections alternating with the narrow sections. Use a duct tape to join them. Flip the panel on the other side and reinforce the joint.
Insulated Box
1. Fasten the cardboard to the bottom of the reflector by its flaps using the duct tape. Be sure the box is centered.
2. Shred some newspaper and put it into the gaps between the box and the reflector.

Baking Chamber
1. In a plastic container mix black tempera paint with one teaspoon of white glue and two teaspoons of water.
2. Apply two coats of this black paint evenly over the inside of the aluminium foil loaf tin and set it aside to dry.
3. Find painted tins that fit exactly in your baking chamber.
Test It
1. Preheat the painted tins inside the solar cooker before cooking with them.
2. Place the baking chamber into the bottom of the reflector.
3. Prop up the reflector with the help of bricks etc to keep it at right angle to trap more heat from the sun.
Your dishes are ready !!!
