There is no space below the mirror, unfortunately, being an ultra-light. They're pretty compact down there, but I have recently added a fan to blow across the mirror to experiment with removing boundary layers. But I didn't have it on that night. I think among everything else I was trying to figure out, I just kind of forgot. Or maybe I was concerned about power, even though it only takes 0.3A. not sure why I didn't. I'll do that next time.
I wonder why it is that moving air (which is exactly the same temperature as the still air) doesn't deposit dew?
