Great idea- may be the same idea on a small. flat cat-food can would act like the old time solar cigarette lighter?

If the optical qualities of the mylar were better or more linear, would make a great variable focal length mirror.

Very interesting. Some years ago I did something like this using a polyethilene basin, about 20 inches diameter. It was enough good to cook some hamburgers.
