Apparently they use sheet of plastic to trap moisture from the air.
the heat of the sun somehow evaporates the water which then is trapped in the sheet of plastic.

a boy scout thing. you put a sheet of plastic, 4'x4' or so, staked about 4-6"above the ground. Put a stone in the middle. Water evaporates from the ground, gets trapped by the plastic, and runs toward the stone, and drips into a bowl. Strictly a survival measure.
