Another low cost method is to use the common household dehumidifier which can produce up to 70 pints of water daily – depending on average humidity. For best results place the dehumidifier outside in the shade; it will even capture some of your plants transpiration – the ultimate recycling.

The water can be used for garden irrigation by means of a gravity fed bucket drip irrigation system. For drinking simply pour through a filter and sterilize with a UV steripen.

a way to minimize the energy needed to produce fresh water in large amounts from, e.g. seawater is using solarpanels, electrolysis and hydrogenfuelcells. the electricity needed to produce hydrogen comes from the solarpanels, but ALSO from the hydrogenfuelcells. normally people use hydrogenfuelcells for the electricity, but when the electricity is re-used for the production of hydrogen, and the cell for ptoducing Water, the cost on energy is minimal, see the website http://www.atakama.org for details

Dear Sir;
Very in formative and clever idea.
I am 63 years old and have been going to the Mojave and Sonoran deserts with my Father since I was five. I continue to do so with my son.
We go prospecting where there are few roads and less people.
I have always carried a 6ft square piece of clear plastic (we call it Visquine)with us. You can get in trouble in 120 degree heat and have no water.
You dig a 4ft.x 4ft.x 3ft. deep hole, put a cup of some kind, cup, can, even once used a hubcap, in the bottom center of the hole.
Cover it with the plastic and cover just the edges with dirt to make a seal. Last, take a small rock and very gentley put it in the center of your plastic. Water moisture collects on the underside of the plastic and is funneled down to the lowest spot on the plastic then drips into your can or whatever. You would be very surprised at the amount of water collected in 8hrs and this will keep you alive till you can get help.
