I once tried to harvest fog;  but mist.  (hee hee hee) Your opening line reminiscing about catching snowflakes (..er, fog droplets) is equally funny.  Thanks.

This conjures a faded memory about a movie I saw years ago when I was a kid;  It was about a group who survived a plane crash in a dessert, and they  were struggling to find water.  The professor (there's always one thinker, as from Gilligan's Island) salvaged some plastic sheet from the plane wreckage and staked it out, a few inches above the ground, with a small rock in the middle, creating a low point.  Placing a cup under the sheet at the low point would catch enough ground condensation for one cup of water per day.  I saw that movie at least 40 years ago (can not tell you what the movie was), but always remembered that trick.

W60, in an area that had lots of water, such as a rain forest, there would not be a need for a fog catching system because there would be plenty of water available. As for fog contaminated with chemicals, if you are desperate for water that would be a small concern. And really, if one is so very enslaved by fears about everything, then leave the water for others to drink. 

While a source of drinkable water in the deserts would be very handy, it is not likely that there would be any fog in desert areas. The fact is that in order to have fog you need to hace a good bit of water, and deserts seldom have lots of water. Lack of water is one large requirement for an area being a desert.

Pubudu,

I don't know this for a fact, but I'd wager that you'd probably want to run it through a filter of some sort before drinking it if collected in areas with a lot of air pollution.  Smog, acid rain, etc. are all good enough reasons if you ask me.

Cabe its true that Fog-Harvested water is pure enough to drink directly but is it true for the urban environment which has polluted air?

Is there a potential of drawing off so much fog that it would effect the environment i.e. rain forests becoming more arid?

 

Also, coiuld there be a problem harvesting fog that has been contaminated with air born chemicals, which I believe is where the term "smog" came from?

 

If there is a potential for use, then this could make a dramatic change in how people live in deserts or survive in stranded situations.

The clip doesn't show how it worked out, but they did end up with plenty of water with their setup. Enough to fill their carbouy anyway.
