Solar Cooker - using a cardboard box construction lined with aluminum foil to harness the sun's energy for cooking your meals, dehydrating foods, and even purifying water!

Recipes can be found at: http://solarcooking.wikia.com/wiki/Recipes

or http://www.sunoven.com/sun-cooking-usa/how-to-use

Step 1: Materials Needed

Cardboard box (large enough to for cooking pan or pot to fit in)

Aluminum foil

Oven bag (large enough to cover opening on side of box)

Box cutter

White glue

Straight edge

Pen or marker

Step 2: Draw Line on Box Top

With the box top closed, using the straight edge and pen draw a line from the upper right corner to the midline of the box.

Step 3: Cut the Box Top

Using the box cutter cut the box top along line.

Step 4: Draw Line on Box Side

Using the straight edge draw a line down the midline on the side of the box to meet the cut made in the top of the box.

Step 5: Cut Side of Box

Cut down the side of the box along the line.

Step 6: Draw and Cut Bottom of Box

On the bottom of the box, again using the straight edge, draw a line from the upper left corner to the midline of the box to meet the cut made on the side of the box.

Cut along the line.

Step 7: Open the Box Up

Open the box up along the newly cut lid. Glue the flaps inside the sides of the box together using the white glue.

Step 8: Draw Window

Close the newly formed lid and draw a window leaving approx. 1 inch border.

Step 9: Cut Window

Cut along the line to create the window in the lid of the box.

Step 10: Apply Glue to Lid Window

Open the box lid and apply glue around the edges of the window.

Step 11: Apply Oven Bag

Place the oven bag over the window and press down along the glue edges.

Step 12: Trim Over Bag

Trim along the edges of the oven bag. You will need to glue the second layer of the oven bag down to the first to keep it doubly thick.

Step 13: Glue Inside of Box

Apply glue to all the interior box surfaces.

Step 14: Apply Foil to Inside of Box

Place the aluminum foil to line the interior surfaces of the box.

Step 15: Glue the Lid Flap

Close the lid and measure where to create the corners using the flaps. Apply the glue to both flaps and seal to create the corner.

    I may consider adding some fiberglass matting under the box (and around it)

    Great instructable!

    I was with you up until the very last step. I don't understand how you're creating "corners" with flaps?

    Look at step 9 and you may see what he means.

    I cannot describe it, it took me a few minutes to see what he is doing.

    The bit he is glueing is the lid (with the oven bag) so it closes, does it make sense?

    Just wondering if this would work in cold, sunny weather.

    A modern day microwave without all the electricity requirements or the micro-waves. Brilliant! :)

    I love the explanation- almost any kid should be able to do this- and that is a compliment!
