An old scout trick to get water out of the air is to use a plastic sheet to make a "solar still", moisture condenses on the underside of the sheet and is collected in a cup. The environment provides the energy and moisture.

That is a cool trick, but in that case the energy gradient is from inside to outside the sheet (sunlight heats the air under the sheet), right?

I'm sure the researchers have thought of this, but it wasn't in the abstract.
