Seeing IS Believing except when the subject is freshwater. We usually conclude that there is no water when we cannot spot any where we are looking.
Water in Air Is nearly all in Vapor Form
The moisture in the air is essentially in vapor form and our naked eyes cannot see any gas or vapor.
Clouds are visible to us because of the liquid water droplets that are dispersed in the air that makes up the cloud.
Fog is another example of us being able to see the moisture in air because some of this water exists in liquid form.
An Air-Moisture Map
NOAA/ESPL have mapped the moisture in the air we breathe i.e. in the air at sea level.
The average water content of this air - the air all around us and the air we breathe - varies from a low of approx 2.4 grams per cubic meter to a high of approx. 24 grams per cubic meter. The maximum amount can even exceed 26 grams per cubic meter but this concentration exists in only a very few places.
Water Amounts in Air
Using the conversion (1 cubic centimeter (cc) of water weighs 1 gram) the moisture in 1 cubic meter of air varies from approx one-sixth of a tablespoon to over One-and-a-half tablespoons.
Thus, approx. 16 cubic meters (565 cubic feet) of air contain a cup (16 teaspoons) of water. Or, the air in an average sized room 8.5 feet high, 12 feet wide and 12 feet long contains a bit more than 2 tablespoons of safe water!
All that remains to be accomplished is to capture this water for local use. Isn't this a challenge worth overcoming?
