I thought I would start a discussion with others who use low or no energy cooking methods. 40° C / 104° F where I live this week (France) so other than saving energy and money, it’s great to get the cooking done mostly outside to avoid heating the house more than necessary !
At our house we have a homemade Solar oven and a homemade AND artisan made Rocket stove.
I have mentioned before that we have a commercial solar oven that looks a lot like yours, and if I want to get temps much higher than 325F, I have to fiddle with it and adjust it to face the sun about every 10 minutes. More frequently if I want to get closer to 400F. It’s kind of nice to have, but it’s far from a ‘set it and forget it’ kind of thing. I’ve seen solar powered motors that track the sun and adjust automatically, and they’re pretty cool, but I’m not ready to make that leap yet.
