    dig a hole about 3 ft across and 18inche,s deep..............put a can or cup in the middle ove the hole ......then cover the hole with a plastic sheet (bin bag/survival bag) place stones around the edge of the sheet to help seal the edges against the ground ...then place a small stone in the center of the sheet to help make a low point in it above your cup/can ........................

    what happens? .......

    the plastic sheet works like a green house and raises the temperature of the air and ground bellow which in turn produces vapor. this then condenses on the under side of the plastic and then drips into your waiting cup...

    the good thing is a still this size will produce a pint of clean drinkable water a day (in warm weather)

    this kind of still can be used to make clean water out of contaminated water as well all you need to do is place the contaminated water in the pit in another container and the stuff that gathers in your clean cup will be safe to drink..............matt

    Actually it could be adapted to do such a thing, you could use it as the condenser side of things. But that would be illegal in the UK;)

    I've seen this method on TV many times and, because it seems pretty simple, I think I'll give it a try someday (I will make some salty water in the first place). When I will do that, will take pictures and I will post them here.

    :cool:

    It's best if you use a black plastic sheet (absorbs heat best.. But i was wondering if using a space blanket painted black on pne sude would be better because the black would absorb the heat, but the silver on the inside would bounce the heat around and make it warmer?

    Hmm. Seems a good idea. Maybe it worth trying. As I said, I'll try the classical method as soon as I have the opportunity. Maybe someone who tried this can tell us more about it.
