Hello!
I was wondering how many people use solar ovens on here? We just built one (working on building and earth oven but I work slow..lol..)
I'll try (not really sure if I know how) to post a picture of the one my husband made (I still have to put the top on today.)
My husband basically made a box inside a box with foam(EPS insulation) in-between. The material that you see is black 5 mill fluted plastic. The sides are just Aluminum foil covering the plastic. There is no glue used on it. I'll be using it today so hope it works good.
