Do any of you have much experience with solar baking? Since it's so hot here in Baltimore today I figured I would finally try it! Trying to bake a loaf of bread right now... I'll check on it at 3 p.m. and see how it looks.
I parked my truck in the most open, sunny spot of the parking lot this morning and let the pan pre-heat from 9 to 11:30. Then I dropped the dough into the oiled roasting pan and closed it back up. Around 1:30 I moved the oven 180 degrees so that it's still getting the full rays of the sun. There are intermittent clouds today even though it's very hot, so I'm not sure if it's going to work, but we'll see!
I'm also a little worried since I forgot the clear plastic that goes over the pan to hold in the heat, but hopefully the black plastic liner of my truck will help keep the temperature raised. Also, I probably could have figured out a better parabola for my windshield reflector to maximize the heat a little more.
Not sure if bread was the best first experiment since bread really does better at super high temperatures to get that nice crust, but I'm curious to see what the results are in any case.
Maybe a better first experiment would have been dehydrating some tomatoes or peaches... perhaps I'll try that tomorrow!
Anyway, here's the dough when I first put it in at 11:30 a.m....
We'll see how it turns out!
It would be even more awesome to do this experiment in the big basket on my bike for the ultimate renewable energy machine! I thought about it this a.m. but biking to work with a big bowl of dough, windshield reflector, and huge roasting pan was a little too much to figure out last minute. Maybe next time!

Aw, end report is not good Cornelia! I had a feeling that my oven still wouldn't get hot enough... I didn't cover the roasting pan with a plastic bag to hold in the heat, and I don't know if my reflector was set up at the right angle. I think I'll try crackers or something next time instead of bread!
Sorry it didn't work out in the end. You really needed that oven bag (or you can use round pans and 4 qt. pyrex casseroles—one upside down—for a cover). The oven bag makes an astounding difference. You are also far enough north that it will help a lot if you set the shade into a tub or bucket that let's it blouse/cone a bit under the food/rack, to let the light under. But you are ALMOST there. Solar cooking does work. I can use it more than my stove six months of the year way up in northern Idaho. Here is a section of wiki page with one of my best set-ups for a windshield shade. I can get two gallons of camp water hot enough for dishes in half an hour in that puppy if the sky is right, or start early and cook up to ten pounds of meat or a couple gallons of soups/stew. The link will take you to the part with the picture (click on it to see the close-up), but the whole page is worth careful attention if you want to cook with windshield shades. http://solarcooking.wikia.com/wiki/Windshield_Shade_Solar_Cooker#.2...
LOL... I'm the opposite of Aliza now. I hate it when winter rolls around and I have to pay if I want to bake bread! I bake far more of our bread in summer when the power is free. Solar breads are wonderful. I don't have a rig to do far-end crispy-crust artisan, but all the more everyday breads come out much better in solar cookers most of the time. Here is a link to a picture of a batch of solar Challah:

Oops, didn't look at the dates. Guess this is an old post, so maybe Aliza has it all worked out by now.:)
Sharon, I am so impressed that you got this to work! Your tips were very helpful, thank you. I shared your photo of the solar baked challah on our Facebook page, it is amazing!
