Insulated Solar Cooker

The goal of this project was to create a box cooker that can cook chocolate chip pancakes and quesadillas. We did not want to spend too much money creating this cooker so we brainstormed materials that would be easily accessible. Anyone can have access to the materials we used; there are also many substitutions to use. The maximum temperature tested was 86 degrees F. People who have high electricity bills, use wood stoves, are at risk from pollution, care about health or the environment, or just like creating DIY projects to reduce their carbon footprint would be interested in building this cooker. Believe it or not, this project took about 10 hours to make. We made adjustments a lot along the way because materials changed and new ideas came along.

Step 1: Gathering Materials and Tools

Materials: 
Adhesive Spray*
Aluminum Foil (Heavy Duty)
Black Food Stand*
Black Spray Paint
Cardboard Box
Duct Tape
Foam Cardboard
Hay*
Plexiglas
Reflective Tape
Scrap Paper
Wooden Sticks (2) 1"x 12"

Tools:
Box Cutter
PVC (Polyvinyl Chloride) Pipe*
Ruler
Scissors
* alternatives can be used

Most of the supplies were free because our Physics teacher owned the materials, but many of the other materials are inexpensive. You would only need to buy aluminum foil, which can be purchased at any grocery store. Also, many of the materials are interchangeable. We used both aluminum foil and reflective tape, but you can use either. Cardboard can be obtained from any shipping company. The PVC pipe can be replaced by any old pipe or piece of wood to hold up the parabolic reflector.


Step 2: Spray Painting the Outer Box

Tilt the box towards you and hold the spray can six inches away from the bottom surface. In smooth, even strokes, slowly spray paint the bottom of the box. Add additional layers as necessary. Leave out in the sun to dry. 
WARNING: MAKE SURE YOU DO THIS OUTSIDE!
