When I saw this in a construction dumpster yesterday I felt it was begging to be turned into a solar oven, perhaps using the projection TV fresnel lens I scavenged curb side 2 weeks ago. A home is actually being built on my street....I stopped to slip the shiny Mylar off AC conduits to use in the living room then saw this too. I'll check today as a slab of could make a great bottom for the oven.
