DEnd, good ideas, yes I was thinking of having a pot just sit on the solar cooker with a one way valve letting air/water vapor out, and let it sit through the night cooling it down to use the next day. I don't run any dehumidifiers at night, so night time running isn't needed.
I will start experimenting as soon as the salt arrives tomorrow.
Though I am still planning on the heat pump build as well. Just to see which is the easiest/cheapest/best.
I only used 17 kwh of power yesterday. Finally getting into a good green range, though I did have to paint the roof white......
more soon,
Shalom
