At the 58 minute mark on the podcast, it was mentioned that there was condensation, that some of it froze on the windows, and it would likely be better if the temperature was closer to an even 70, rather than the 50 it tended to be the first year. It was mentioned perhaps to put a dehumidifier in there and run it off the volts-wagon.
I have a thought inspired by these two videos. This engineer experimented with making a desiccated air-conditioner. The idea was to dry the air by blowing it through water drops saturated in Calcium Chloride (used as a food additive or de-icing sidewalks, etc) which absorbs humidity. This raises the temperature as it drys the air; you have a different setup to do a swamp cooler effect to cool it.
But, elements can be used from this to just dry the air. I was thinking of trying something like this, a different element in this system, to evaporate sap to make Maple Syrup.
He shows you can run this just off of solar, and there might be a way to just run this off the wood stove.
Edit: (This is a recognition to make this post more useful, a brief description would cut down on a lot of time)
The mechanics of this is basically three tubes with air being blown in from the bottom, and water droplets being dropped from the top of the vertical tubes.
One tube would have air coming in from your living space, and have water saturated with sodium chloride at about room temperature. When the air passes the droplets humidity is drawn out of the air. This also has the effect of warming the air, because water vapor is condensing to liquid.
The second tube could have normal water dropping through the air from the first tube with air dropped to room temperature, which would cool the air like a swamp cooler.
The third tube would be outside, and have the diluted water from the first tube to heat it first, either by a solar panel or perhaps a wood stove, and use outside air to take the moister away, thus leaving the sodium chloride solution less diluted.
It was the first tube that I thought would be good for using as a dehydrator for the Wofoti, and the third tube to complete the cycle for the water.
It was this third tube that I wanted to think about doing it for Maple Syrup. I think it would take a lot less wood thank a conventional evaporator.
This is just a rough idea what the videos show. I am probably making an error somewhere.
