I have been an avid subscriber to the Instructables email list for a few years now and occasionally there is an instructable that catches my interest. This week’s edition had two such items – The Office Workers Portable Solar Oven and Non PV Solar Power. I’ve only read partially through the second one, but the first one, the solar oven, has re-kindled my intentions to rebuild my first attempt and second attempt (part 1, part 2, part 3, part 4) at a solar oven. I think this time I’ve got some pretty good ideas and, as usual, I’ll take some pictures and document my trials and tribulations in the endeavor. My goal this time is to pop popcorn!
The Office Workers Portable Solar Oven Instructable apparently wasn’t highly successful, but that may be due to the projects strict guidelines of using only what was readily available around the office that he worked at. I believe his biggest downfall was using a piece of a clear garbage bag as the cover for the top instead of being able to use glass or plexiglas. He did have an amazing amount of technical information provided on how he calculated the efficiency of the oven – which I’ll try to duplicate in my reporting of my third attempt.
