Solar ovens

Due to shift-work, my family had Thanksgiving today. I realized today that I really could have used a solar oven.

Tim, I know there is some way to make cardboard significantly more durable by coating it in some sort of paint, or corrugated paper, or wood seal or something. I know I've seen a thread about it on another site, but I'm having a difficult time finding it. Once I find it, I'll post it here.

Or we can utilize all those campaign signs?

My thought with wood was that in addition to strength I might also be able to make it collapse flat for storage with some clever design. Plus, I could cut multiple copies on my CNC.

I'm going to combine a solar oven with a fersnel lens. Has anybody ever fried a turkey using a fersnel/solar cooker?

Edit - I recall seeing a version that lined the inside of a solar oven with black bricks and achieved a temp over 300. Unrelated to turkey frying.

I'm interested in the umbrellas. I wonder how effective a 36" diameter umbrella could be if the inside was coated with foil or reflective tape? it's appealing to me because it could be made cheaply from things I have sitting around and it folds down nicely.

I did the satellite dish thing this sunday, was able to burn soda cans with it. (smoke rolling off the can) too hot to touch - easily burns your hand. (ask me how I know)

I was running out of sunlight, but was getting 150-170 degrees easily.

So it makes me wonder, if I pointed the dish into a solar oven or fresnel lens?
