Thanks for the links Jeff, those would for sure be more simple.
I have access to one of those large (12' diameter) smooth surface satellite dishes that I though of coating with mirror tape and building a solar tracker for. Other than needing flexible hoses to follow the tracking dish the design would be able the same. This is the perfect "grid down" way to keep things cold.
I am still really struggling with the design of this whole thing, it was simple enough to just look at a hvac unit and put in parts where I needed them. There are not many examples to just look through..... But once i get over the learn curve I think I can do this rather quickly.
