The goal of the project was to design a solar cooker that can boil water to cook instant noodles. The maximum temperature was 115 degrees Fahrenheit. This project would interest people in third world countries who need to cook their food, but do not have a lot of resources. These materials should cost under $20, and most if it can be recycled. It will take about 3 hours to assemble, and the final project should be square feet. Scissors and box cutters are dangerous, and sunglasses should be worn when cooking to prevent vision damage.
-3 foam sheets (21 in X 21 in)
-1 foam sheet (18 in X 8 in)
-1 roll of reflective Mylar
-4 Popsicle sticks
-a pack of ramen
-a roll of string
Cardboard can substitute for foam sheets. Reflective tape, or aluminum foil can be used to replace the Mylar. Wooden pencils or any strong stick can be used in place of the Popsicle sticks.
Step 1: Physics of How It Works
The mylar covered foam pieces capture the light from the sun. The reflective pieces is angled to reflect all the light to focus on one point, which is the black pan. Since the black color absorbs light (unlike white, which reflects light), the light energy is turned into heat energy. This heat energy is used to heat up the water in order to cook the food.
