Water:

My desert survival kit:
Pocketknife
Clear plastic sheet, folded into pocket size
(pocket determines size)
Long string.
Directions:
1 pick location with things growing (indicates water below ground)
2 cut small twigs, leaves, etc. & a couple of thin branches.
3 cut a small piece of the plastic sheet and make a 'bowl' over a scaffold of bent twigs
4 dig a small hole (branches make digging sticks)
5 set bowl in bottom of hole
6 place greens/vegetation around bowl and in hole
7 cover top with clear plastic sheet
8 place rocks on edges of plastic sheet
9 place one small rock on top of plastic, located directly over bowl beneath
10 wait
sun's heat will evaporate moisture from vegetation
condensate drips down sheet to lowest part/ below rock
condensate drips into bowl
Repeat as needed.
Note: Same idea works on brackish or sea water
Warning!
Never scoop out any cactus and ingest sap.
You can cut up cactus to place in hole, then drink condensate.
Nuther solar still: a black plastic garbage bag, placed over a living branch of a tree for the day. Change trees every day, so you don't damage a tree too much.
Idea that has worked for a friend:
Pipe (pvc ok, 4 to 6 inches) about 1 1/2 feet long.
A layer of muslin
A layer of some very fine material
A layer of sand
A thick layer of REAL charcoal -- NOT charcoal briquettes!
Another layer of sand and all the other stuff above in the opposite direction.
Pour the water into the pipe at the top, where you have left a bit of a depression in the muslin to "hold" the water as you pour it. Change the charcoal fairly often.
For charcoal: Cook wood in a closed container until it's black. It won't burn in the container because it doesn't have enough oxygen, and a CLOSED container will allow steam & such out without letting too much oxygen in. I saw a show where they were making huge batches of it the old-fashioned way -- it was really great!
It takes a matter of hours for the wood to become completely black. That carbonization is what "catches" the particulates in the water.

Solar Stills operate on the same principles that produce rainfall. The sun is allowed into and trapped in the Still. The high temperatures produced destroy all pathogens. The water evaporates, and in this process, only pure water vapor rises in the Still, only to condense
