Capturing moisture from fog...

[Externet]

What would yield best efficiency in collecting moisture from fog ?

 

The typical fabric used for such is the raschel, that one used for bagging potatoes, onions...

How can the dimensions be optimized/engineered ? Larger holes allow more fog passing trough; smaller holes impede the fog flow but present more moisture capturing surface. There has to be an optimal ratio from thread/ opening. Probably depends on wind speed, humidity content. How would you chose the ratio ?

 

Now, about material... Is a multifilament wick 'better' at capturing/transporting the collected moisture than a polyethilene thread ?

Better could mean faster channeling, less evaporation, aseptic, durability, higroscopy, price... what is your opinion ?

 

About knitting pattern... which would capture and convey the collection in a 'better' way ?

How much moisture is there in the air? You must know this data to understand how big a collection collector you need, and how fast the wind (or fan) needs to move the air through your collector.

This is not about volume collection ; it is about efficiency. Read again. If it was about volume, bigger simply collects more.

To find the best efficiency would take some experimentation and/or research; although, you might find someone who already knows; I do not know.

 

Nevertheless, you may or may not be able to afford the most efficient material. I would want to know how much water could theoretically be collected at 100% efficiency, the longevity of candidate materials, and other economic factors to be able to judge which is cost effective.
