Evaporation and Condensation: Daily Tug of War

Principal of Phaethon Research for Clean Energy and Arethusa Investing In Clean Water
Above is a photo of dew on plant in a desert in Namibia. In the hottest and driest deserts there is wealth of evaporation during the day! Yet the combination of temperature drop and existence of cold surface enable water vapor to condense into water at night!
We know that Type A and Type B, molecules in vapor phase, can gain or lose energy in heat transfers to air, water and other surfaces. If the heat loss is great enough Type A and B can become Type C or Type D molecules.
In The Phaethon piece " Controlling Evaporation in Reservoir or Canal Boils down to Maintaining and or Enhancing Surface Tension", surface tension is presented as the focus of evaporation control in a reservoir or canal. But inducing condensation is another possible approach. In Chile and other foggy places, nets catch windborne water droplets sufficient to support small scale farming!
The fog net technology is based on capturing windborne droplets of water. With a small lake, reservoir or canal, nets can be strategically placed in the path of the wind to capture droplets! However if the nets are cold and hydrophilic. there is potential for the net to induce condensation of water vapor!
