Dew

Any natural or created temperature gradient can produce the dewing process. This process is based on the fact that cold air does not hold as much water as warm air. Cool the air and the water falls out. The larger the temperature gradient the faster the process. It also helps if the cooler area is higher than the hotter. For example if you have warm ground and cool air then just put up a distilling tent. This could be as simple as a clear plastic tarp in a tent shape over some wet ground.

Best shape is an A shape where the sides have roughly about 45 degree angle. PVC pipe with joints could be slipped together to form a tent shape with the plastic over the outside. Ropes over the top staked down on each side hold it down. The bottom of the plastic folded under a PVC pipe at the base of the perimeter. The plastic would be wrapped around the base perimeter made up of PVC pipe. The distilled water will form as droplets on the inside of the tent and run down into a trough made by wrapping the plastic around the base PVC pipe. This is the space between the plastic and the pipe.

Don't let air in, keep the tent closed on all sides. Fold the ends like wrapping a package. Wrap the bottom of the ends around the PVC pipe. Wait until the water begins to puddle in the plastic wrap around the edge. Dig a hole at the lowest point or points and put one or more containers to capture the distilled water. Put a small hole in the plastic to let the water drip into the container.
