Cooking with a solar oven

Postby Redneck Teepee » Fri Nov 14, 2014 8:22 pm

Anybody use a solar oven to cook with while camping? I searched the topic but did not find much.

Note: All of my solar oven cooking was done in the summer months of July and August.
I purchased one a few years ago to try out, cooked a few things in it, found it to be more of a pain in the ass than useful.
They have their place where they are very useful or the only thing useful, but I don't do that kind of camping or outdoor activity.

The biggest problem is if you really want max heat out of one, is you have to attend it every hour or so to rotate it for maximum sun exposure, and that all varies for the spring, summer, fall and winter position of the sun.

The best and easiest thing I found to prepare was a cobbler that I started in the morning and left the oven in a sun neutral position, the middle of the daily suns arc so to speak, did not tend it or move the oven and it came out delicious by the evening for our regular meals dessert. Have not tried bread but I'm sure it would cook just as well over lower heat and a long sun arc.

You can use it to cook in a small dutch oven, but you would have to tend it for max temperature, which I have reached over 350 degrees with it.

Just curious if others have one, or have experimented with one......Larry

Several years ago I was working grave shift, and since I was home every day during daylight hours I did a lot of solar cooking. I have a home-made cookit http://solarcooking.wikia.com/wiki/CooKit and a Global Sun Oven, now bigger and better as the All American Sun Oven http://www.solarcooker-at-cantinawest.c ... _Oven.html. I'm at 35 degrees 53 minutes north (northern New Mexico, USA), 7200 ft above sea level, and did my cooking in October, November, and December. Oh, I do some solar cooking in all seasons, but that three-month period was my most consistent.
8)
With the CookIt, I used a blackened SS bowl in a clear glass (Pyrex) casserole http://www.amazon.com/Pyrex-Bakeware-2- ... ered+pyrex, creating a "greenhouse" cooking container. A similar, much larger vessel is used with the HotPot solar cooker http://www.solarcooker-at-cantinawest.c ... okers.html. I was able to get my rice dishes to boiling in October, but the Cookit is very touchy about breezy weather. It works, but now I use it only occasionally, mainly as a way to keep hot things hot, but not to get them to temp to begin with.

I was able to cook full meals and even bake in the Sun Oven even on Dec 26. My habit was to re-aim the oven one or two times an hour. In our cool, clear air, the oven was usually able to maintain a temperature over 300 F around mid-day with my aiming schedule, which meant I could cook a meal in a couple of hours, including biscuits or cornbread.

The Sun Oven also catches every breeze, but it has more mass and is less likely to sail off and dump a meal. That said, OctNovDec are relatively calm months here. I have had much more trouble with the Sun Oven when camping in the spring (Wind Season) and summer here, the months when we have fire restrictions in all the forests of the southwest and therefore could use the solar ovens! The sun is more directly overhead, but the wind blows more.

Yes the Sun Oven is the one I purchased, and yes wind is it's enemy as far as blowing over or off kilter of where you aimed it.

Never had trouble getting the meal cooked it just takes way too much attention for my liking. If you got some one in camp with nothing better to do that can watch it, I guess it would be a mute point.

With no fire, stove or other heating apparatus it serves it's purpose well. :thumbsup:

Stupid question?..........................Does anyone make a solar oven that has the ability to track the sun. I have never used one but have been intrigued by the idea of cooking with the sun.

We’ve done lots of Solar cooking .... made solar cookers from cardboard boxes and tin foil ... all worked fine ... Cooking around noon worked best for us , and there wasn’t much to attend to since everything cooked in just a couple hours... :thumbsup: 8)

Solar tracking

This is so easy, even a child can do it. Not so sure I could figure this out.

That is just too cool - perfect for smaller PV panels for battery tending, cookers, who knows what else. Great find!

Nose, that is pretty ingenious huh? :thinking: Not really necessary for cooking ... and while cooking over a couple hours , we might move the reflector cooker once or twice (maybe) ... It’s not necessary to have it exact all the time ... Good design helps with this too ... a Reflector type oven is much less subject to angular differences than say a focused lens type of cooker ... We tried a bunch of things , Fresnel lens, glass lenses for cookers ... Those required constant adjustment , but cooked Very Fast ... lots of ways to cook things with solar ... even the solar Pizza box works to some degree...... :o
