HOW TO CREATE YOUR OWN SOLAR STILL:


Dig a shallow hole in the ground, place a lose sheet of thin plastic over the hole (be sure to put enough weight around the edges of the plastic so it will not be pulled down completely by the weight of the water it collects overnight), place a vessel at the middle of the hole and under the sheet of plastic to collect the water overnight and put a small rock at he middle of the plastic sheet to create a slight incline towards that center and wait till morning. Depending on how large the hole, sheet of plastic and container for the drinking water you will have drinking water. Those who grew up in the desert should already know this and those who are considering moving to the desert should learn how to create water out of the thin air.

It is a nice design, but it is nothing more than a solar still. As YukonJack said, a sheet of plastic , a shallow depression or large pan, and a collection cup will do the same thing, and weigh far less and cost less.
If you take a large shallow pan such as a kiddie pool, put a collection pot in the center, fill it with undrinkable water. (salt/dirt) stretch a sheet of plastic tautly over the top to seal it, then add a weight in the center of the pool directly over the collection pot, the sun's rays will distill that water into condensation on the plastic roof which will drip into the collection pot. The larger the surface area of the shallow pan, the higher the amount of water collection from condensation. This is a basic survival technique called a solar still. There is a blow up version now available for life rafts at sea.

Yukon Jack is right. I've used the plastic sheet and bowl method to collect water from moist ground and to distill muddy or brackish water.

They teach this principle in the Boy Scouts. You dig a pit, place a container in the center, cover the pit with a black plastic garbage bag and secure it, then put a rock in the center just above the container. The sun warms the air in the pit and draws moisture up from the soil which condenses on the inside of the bag and drips into the container. It's slow, but produces fresh water.
