My brother has a small oven he bought one time, long ago. These ovens are amazing! You can build them, really, out of anything from cardboard to wood and I think it would be great to make one with a glass window on top that you could see things cooking but nothing could get into it. This is definitely one on my to do list. Besides, it’s just fun to use solar energy to cook!
The website above has lots of info about solar cooking and the results of my experiments this summer I will post here.
Also, Backwoods Home has a lot of information on solar cookers and loads of other information as well.
Happy Cooking!
