SURVIVAL IDEAS, STORIES AND KNOWLEDGE
We are now living in exciting times, on many levels.
Let's take a look at practical ways to prepare our lives, in every area, for an easy, pleasant and generous way to survive.
EWA Technologies Group
has developed a new technology that harnesses the natural humidity in
the air, and converts that moisture into drinking water. The process
works in three stages: Adsorption of water from the air (getting the
water out of the air); desorption of the water (releasing the water out
of the containing material); and condensation of the drinking water.
The first, and probably most critical phase is that of removing the
ambient moisture from the air. This is accomplished by using a desiccant
material (something that will attract moisture). Since this process
actually releases heat, very minimal electricity consumption is
required. Basically, all that’s needed is something to keep the air
Releasing the water entails a combination of wind drying, heating and
negative pressure (a vacuum). Using this combination of techniques
requires only moderate heat (about 60º C).
Finally, since the steam is at a very low pressure, it begins to
spontaneously condense. Using the heat recovery unit cools the steam
further and prevents heat loss, allowing the reuse of up to 80% of
What does all that mean? Under some circumstances, water production
is about US $0.50 per cubic meter of water. And that’s worth drinking
to. Image Credit: The World of Water by Snap® via Flickr’s Media Commons
