Just took delivery of a solar oven called the Global Sun Oven. Going to record some of my learnings in this thread. Hopefully you folks with experience will jump in when I'm off track. So Calif is blessed (and cursed) with lots of sun. Thinking through potential scenarios, it seemed that having an off-grid oven would be a worthy prep. For food of course, but also for water purification. As you know I'm a bit of a 'solar still' nut, and while Calif can run out of fresh Northern Calif water in a heartbeat, we have loads of salty ocean water. A solar still would turn that into fresh. Two of the ovens (below) had slanted-top doors that might allow them to do double-duty as a dandy solar still. We'll see. Wasn't easy to research, not many people comparing the ovens head to head. One of the few: http://www.comparethebrands.com/compare/60 The Sport Solar Oven was attractive to me because of its simplicity, low profile, and angled double-pane lid. A reported potential for warpage (all plastic construction...my plastic tub solar still warped immediately, so I was leery of that) and more in the crock pot range with top heat of 250-300F. Cost $200 w reflectors. The other alternative that caught my interest was the Global Solar Oven, angled lid, top heat 350-400F, and an anodized aluminum interior. I really wanted that anodized aluminum interior, and the additional heat didn't hurt, so I ante'd up the $260 and purchased on Amazon. Showed up in about 4 days, well packed. Simple construction, and I'll admit to a wave of regret when I thought about how I might have built something myself, like Quake did. There are parts of the oven that are surprisingly low tech, like the poplar wood frame to which the oven door and reflectors are screwed with wood screws. But then other parts are far beyond my ability to create, such as the formed, anodized aluminum tub, and the plastic outer tub that is sized to it. There's insulation between the plastic and aluminum walls. The folding reflectors would not be easy to duplicate either; they are polished and then anodized aluminum. A nice touch is the gimballed bottom to the stove, so the pot/pan stays level despite the tiltage of the oven. And on the other hand, the reflectors are kept in place by sliding over an oval thumbscrew head (ultra low tech and certain to mar the reflector in that area), and the reflectors are latched down with a loose snap strap (that needs to be shortened). There's a spring-loaded leg in the back that tilts the oven to match the sun. This leg is crotchety enough that even the promo videos could not make it look smooth, but it works. The oven becomes a tripod when you use it. There are complaints about this oven stinking on eBay. All the greenie chemophobes think it's a deadly "plastic smell." I recognized a smell immediately upon unpacking...it's the oil-based walnut stain they use on the wood frame. I've smelled it during dozens of projects. So that needs to dry out. Sun Oven should probably switch to a water or alcohol based stain and follow with a polyurethane. That would take care of at least some of the smell. However there is a "de-stink" process we are to follow, to make certain the insides of the oven are clean; basically you cook a pot of soapy water inside the oven. As luck would have it the oven arrived on a day of heavy rain, and today, following, are high winds. So I set the oven facing the eastern sun INSIDE the house at 9am, and it attained 200 degrees within an hour, and 300 in an hour and a half. Now to make my first tasty dish: Soapy water. The condensate is sheeting off the glass door and dripping into the anodized tray below, so this looks like it will be a very efficient solar still, probably beating the relatively efficient solar still I already built.
