Water, water, everywhere (from Air)

WATER, WATER, EVERYWHERE, 
NOR ANY DROP TO DRINK. 



The Rime of the Ancient Mariner (text of 1834)
By Samuel Taylor Coleridge

  All in a hot and copper sky, 
  The bloody Sun, at noon, 
  Right up above the mast did stand, 
  No bigger than the Moon. 

  Day after day, day after day, 
  We stuck, nor breath nor motion; 
  As idle as a painted ship 
  Upon a painted ocean. 

  Water, water, every where, 
  And all the boards did shrink; 
  Water, water, every where, 
  Nor any drop to drink.

  Attractive intermolecular forces are categorized into the 
  following types:
    o Hydrogen bonding
    o Ion-dipole forces and ion-induced dipole forces
    o Van der Waals forces - Keesom force, Debye force, and 
      London dispersion force

  Assuming the air is not saturated, i.e. the relative humidity
  is less than 100%, water molecules with higher kinetic energy
  overcome the intermolecular forces and evaporate into
  the atmosphere, warming the atmosphere, cooling the liquid
  water, and increasing the water in earth's atmosphere. The 
  warmer the earth, the greater the evaporation.






REASONS FOR HARVESTING WATER FROM AIR






















CONDENSATION OF ATMOSPHERIC WATER














  Here are some ways that water is being harvested from the
  atmosphere in reasonable quantity using only the sun, wind,
  and gravity (and some engineered materials)
