Drinking the fog

In Santa Cruz, where I grew up, the fog rolls in every summer evening and burns off about noon the next day, so this story about the technology to catch fog for drinking water was particularly interesting to me. Santa Cruz is now looking at desalinization plants to fulfill future water needs, but I wonder if a system to collect the water in fog might really be a cheaper and more energy-efficient system. The redwoods have been doing well with such a system for millions of years.
