... it was possible to produce as much as 6,000 gallons of water
daily for every 1,000 square feet of
condensing surface ...
That works out to just over 1/2 ounce of water per minute per square foot of
condensing surface. Remembering that heat is released as water vapor
condenses into droplets, a glance at a mechanical engineering 'steam chart'
reveals why this idea for recovering water from the atmosphere has not been
demonstrated to date: the released thermal energy quickly heats up the
condenser and the temperature difference between the air and the condenser
approaches zero, at which point no condensation will occur.
