A Larger Solar Water Distiller

Here is a video showing how to make a survival distiller. I would think something this big would be enough to supply water for one person per day, as long as it's sunny.

You could also line the hole you dig with saran wrap, so it will hold water hopefully. Then you could pour water in that hole and set your empty bowl in the middle to collect the purified water.

And remember if you're in a desert with no water around and you have a larger and smaller container and some saran wrap, you could pee in the larger container, put the smaller in the middle, cover it with wrap (hopefully with duct tape or if you have a large piece, with rocks) and you could purify the pee and drink it. Although some here at CZ saying urine therapy is good for you.

Anyway, here's the video and principle.
