I thought of that, but I wonder what my wife would think of several days of having an extension cord running down the hall, into the linen closet, and up through the attic access panel. Putting in a plug would be more "peaceful", but largely useless once the problem is resolved, I suppose. If we were ever doing anything up there (fixing something) I guess I could plug a utility lamp into it, or something.
I'm really just brainstorming off the top of my head here. Don't take any harebrained idea too seriously.
