I had seen some of the adhesive mirror film  ...  but wasn't sure what to attach it to as it's a wide expanse without fitting more cross members. I hadn't thought of attaching it to corrugated iron  ...  that should work. Most corrugated iron nowadays isn't very shiny, so sticking foil to it wouldn't be a bad idea. Probably the best I found was some mini orb  ...  but still not all that shiny  ...  and quite expensive still. I had wondered about complaints about reflections, but we're on a dead end road, so not that much traffic. The local pilots may start complaining though. That outer collection duct has about 2 inches of foil board lining it  ...  so is well insulated. I've resurrected my temperature data loggers and will try them out again to learn more about how it works. Still very happy with the results so far.
