Actually I have put a bottle of water in my solar funnel cooker and left it
out at night when the temperature was in the 50F and had ice form. It will
only do it for me on a real clear night, it does not work on a cloudy night.
Bright Blessings,

Hi,
But, to create ice wouldn't that require the night time temperatures to
get to freezing? Even if the goal was to cool a heat sink, power is still
would be required.

Not shure how much heat you can get rid of in this way. A calculation or

day in their usual way. Mount on top of your dirt mound for shade.
