SIPPING THE FOG
In response to your correspondent Grant Vanderwagen (“Mist opportunities”, Letters, July), regarding the harvesting of water from fog, great idea. Based on my own experience, I can endorse the principle. The arid west coasts of the world could well become significant water-harvesting “farms” of the future.
For 20 years, we enjoyed a beach cottage at Elands Bay. Some mornings our deck, under a roof, appeared to have been hit by an appreciable rain-shower overnight. Geoffrey Jenkins wrote of cairns of rocks, erected in coastal-desert rock-basins, producing perennial water, both used by the peoples of pre-history and the local wildlife.
A warning: corrosion will be one of your greatest enemies. Again from personal experience, it was found that any metal, short of surgical stainless, will be attacked. Good luck… maybe we can enjoy a whisky and fog, one sundown. KEITH HONEYMAN BY EMAIL
