Andy posted this over at SYKW survival forum that I thought was interesting.

Here's a possibility of a inexpensive solar still for 3rd worlds. It's pretty primitive, you have to deploy a few of them to be effective at 1.0 to 1.7 Liters of condensed water per day (24 hours).

Hard to fit in a BOB, though....

Hmm, since it is conical, I am betting you could make a collapsible version just by using a more flexible plastic and instead of having the catch around the bottom belled you could just make a seam fold and it'd still catch the moisture and collect it. Then you could pinch the bottom flat and roll it up into a cylinder. I am also thinking you could make it pyramidal and have it fold flat for transport/storage under the same premise. it might not be quite as reliable, but it would still be a whole lot better than nothing.

As an alternative carry method, you could also put a cone of cloth covering over it with a little rectangular hole cut in the front of the cover and a strap at the bottom and wear it as a cool kung-fu Koolie hat.

You could easily make this an inflatable item I would think.

The bonus while blowing it up is that the moisture in your breath can be caught. LOL

I have seen listings on Ebay a number of times, for the inflatable version which is used in survival kits, although no listings currently. If I see a listing sometime, I will post it, as it may have the manufactures information for direct purchase.

It appears that I am too slow with an idea, once again... HAHAHA

Thanks, Pete!

I think your thinking of something like this:

I'm so slow that multiple products have hit the market! LOL

Actually, looking at the second link, I may have seen that item before. It looks really familiar. So I'm nt slow, I just think everyone else's good ideas are my own.

Did I ever tell you guys of this theory I had? I think I'll call it Quantum Physics!

I saw these on a show a while ago. What a great product. I wonder how effective a really large one of these could be.

I'd think production would be based on the area. Double area = double production.
