As dreaded, I'm finding that my LEAF, like all other cars I've had, accumulates moisture in its cabin that makes it very difficult to keep the windows clear. I've always yearned for an automotive climate control that would offer dehumidification as an intentional feature, instead of a side-effect of running the air conditioner to further chill cabin air that's already uncomfortably cold. I came across a couple accounts recently of industrious DIYers constructing Peltier-based air dehumidifiers, and so I did a little Googling to discover whether any such gadgets were commercially available. Turns out that there are, and I bought one of these EDV-1100
units on speculation, and I've had it in use for the past week or so. With its power cord fed through a nearly-shut window, I'm allowing it to run inside the LEAF's cabin overnight. Just by itself, it's able to extract a teaspoon or so of water in that time, but combined with the timed preheat (er, I mean "Automatic Window Pre-Fogger") feature, the dehumidifier wrings out about a cup
The EDV-1100 seems a well-made unit, although I can't understand why it was designed to run on 9V instead of 12V.
