First of all, a big thanks to the people at the art of illusion forums on sourceforge and also a big thanks to the guy from Sweden who dreamed up a parabolic dish made from 2 parabolic troughs.

I might not have even considered 2 troughs, let alone a trough with wings if he had not done 2 troughs 30 years ago!
Anyway, I do not know how this will turn out.
Thanks to Tom Sponheim of solar cookers intenational for putting it in the right place on their wiki and to "solarcookingnut" on yahoo groups for support.
