Fog Harvesting

I just stumbled onto Fog Harvesting.
I am thinking of setting up a pilot project to see what the cost and yield are for a simple system. If successful I will expand it using my existing storage tanks.  It is completely passive once set up.
It will be interesting to see what yield I get per sq. yd. of material.

Here is another interesting site on this subject. Please comment with what you know about this subject here.

Enclosing The IBC Totes

Above are two pictures of the construction of the enclosure for the IBC totes.  Both picture are from the open end.  The second picture shows the roof sections from above.  Each section is 40" x 10' long.  They lie next to each other with the tar paper overlapping the edge of each section onto the next section.  In this picture there are 5 sections already installed.  That is approx. 200" x 10' or 
16' x 10'.  The first picture shows the same set up from below. Here you can see the tanks.  I have already mounded the wall along the right side between the tanks and the fence.  
With a few more sections I will be done.  The sections are clamped together so that the wind won't blow it away.

For the construction of the roof section I am using very lightweight strips of wood 10'x 3/4" x 1 1/2"
The ribs and ends of each section are 39 1/2"x 3/4" x 1 1/2". Stretched over the frame is a section of plastic fencing material 10' x 40" and above that is the 40lb. roofing material. You can see the sag in the lower photo, but that will be supported so that the span will only be about 5' between the support on the higher tank and the fence.

Fortunately I don't have to deal with a snow load, but I do have to be concerned with rainwater load and wind.  I am installing the sections so that there is a drop of 1/4" per foot so drain the water to one side.  I am using cheap general purpose alligator clamps to hold the sections together so they don't blow away in the wind.

If I have to remove a tank for servicing I can easily remove the roof sections and gain access.

As I add the sides I will shoot some more photos and post them also.
