Clip 2 pieces of 22" x 28"  (55.88cm x 71.12cm) poster board together.
<p>Purple Fig because I entered it into a contest that wanted something to do with cooking and figs. Feel free to make it any color even one of your favorite teams. I covered some in fabric.</p>
<p>Why purple?</p>

<p>I am going to try this, Love it</p>
Solar cooking actually works even better in high elevations because the air is thinner. The air temp has nothing to do with solar cooking. If you check the solar cooking wikia you will see a person solar cooking in Norway in the snow.I am cooking solar fudge right now. The highest temperature I have reached is 475F&deg;. I didn't put that in the instructable because people would doubt it. Most home ovens cook between 250F&deg; and 350F&deg; and that is what my little cooker averages. You need a low dark pan with a tight fitting glass lid to get best temps. There are over 300 people around the world cooking with the Copenhagen every day. I made the purple paper one so Everyone can afford the technology. My hope is that teachers and charities around the world make these. 2 billion people cook over open wood fires in their homes. This cooker will save trees, reduce lung diseases, home fires and burns. OK down off soapbox :)
Well, I wouldn't say that the air temp is if no consequence. If the ambient air temp is cold, it will make the container you're cooking in cold, taking it longer to heat. Also, if the wind is blowing, it will steal heat from the container and its contents as well. Now, if it could be sealed, as I've seen other solar cookers, it would insulate that internal area from as much heat loss.
Good question. Some folks use an oven bag around the cooking pan in windy areas. The continuous curve maintained with this cooker throws the air out quickly (no corners to capture the wind) and it gently waves in the wind. Not much cold air can get to the pan because the area around the pan is hot and hot air rises. For the larger size 22&quot; (55.88cm) square panel with 12&quot; (30cm) base I use a flat griddle with a Pyrex bowl inverted over pan to make a real hot little oven. At 33&deg; lat. I don't use a bag and still get good cooking temps. Bread cooks very well in it.<br>
Intriguing, and certainly attractive. I'm a bit specious of the temperatures, though. If you can show me a video, in outdoor conditions, of the oven boiling 20 oz of water at sea level in a reasonable amount of time (say, 15-20 mins), I'll vote for it. I'm a backpacker, and if this'll do the job in moderately cool (50* F) temps, I'll make one and field test it at some altitude, (3500 ft,) as well.
This video may help. A friend of mine in Canada made this video of my Copenhagen Solar Cooker. It is what I modeled Purple fig after.<br>http://www.youtube.com/watch?v=Gjr-VHq12kk<br>
I love the design! This might be the prettiest solar cooker I've ever seen :D
Thank you!
Once again, Copenhagen saves the day. I TOTALLY love this beautiful purple solar oven.
