It was a long overdue dream of mine to build a solar oven that will work on solar power alone. Finally having some time and a lot of sun I decided to build one according to a plan found on the internet (The Heaven’s Flame Cooker). Since it is the first solar oven I built I decided to follow the plan as closely as possible so I’ll have something that should work and I’m not disappointed. And I have to say I wasn’t… using just cardboard boxes, glue, some black paint, a piece of glass and some aluminium foil the oven is a success (at least in my eyes ). On the first day I used it the outside temperature was around 25 deg Celsius, but inside the inner box the thermometer went up to 120-150 deg Celsius, enough to bake a bread in about 3-3.5 hours. So far I only used it twice to bake bread, but I’m looking forward to test it on a really hot day (40 deg Celsius) and also cook some other things in it. I also got a couple ideas how to improve the design (hopefully) and make it work even better. If I happen to find a good improvement I’ll of course post it here so everyone else can try it too.

Here some pictures while building the oven…
