Introducing the SPAWG (G+ Link)

Water… it can truly be called the substance of life.
It’s possible that life as we know it may never have begun without liquid water. And it is absolutely true that we cannot exist without the presence of liquid H2O. Next to air, water is the most important substance needed for our survival. Without any water at all, we will die in as little as two or three days. Humans can live for weeks without eating… but only a few days without water. Although there’s lots of water on the Earth, almost all of it is undrinkable for us. Only pure uncontaminated fresh water is suitable for drinking and is called potable water.
Water on Earth is recirculated in a complex cycle that starts and ends with water evaporating into the air. Water vapor circulates with the air mass and eventually coalesces into droplets that fall to the surface. From there, the water can go into the oceans and great seas or into streams, river and lakes. Some of this rainwater seeps into the ground over time and collects into aquifers and even forms subterranean rivers and lakes. These underground rivers and aquifers can bubble to the surface as springs which flow back into rivers, lakes and the sea. Then all of this liquid water eventually evaporates back into the atmosphere as water vapor and the cycle starts again. For any particular water molecule, the cycle can take minutes or millennia.
All of these pools of liquid water, from the oceans to the aquifers and all the rivers and lakes in between, are sources of potential drinking water. We have technology that can desalinate ocean and brackish water. We can filter river and lake water and we can drill wells into aquifers and capture artesian springs. But all of these sources of liquid water can also become polluted with contaminants that cannot easily be removed. Or they can dry up. Or they can move or shift beyond reach. Ultimately, any of these sources of liquid water can be altered, diverted, poisoned, polluted, restricted, or stopped in such a way, and without your permission, as to make them gone forever.
But there’s one source of water that cannot be stopped; water vapor in the air.
There are only a couple of places on the planet where the relative humidity is so low that it’s essentially zero. Every place else has water vapor in the air. Even the Sahara desert has an average relative humidity of 25%. Water vapor is the first step in the great cycle of water on the planet. That’s why you can’t stop it. As long as there are pools of liquid water, evaporation will occur. Water vapor in the air is the first and only guaranteed source of water.
However, there’s a serious problem with the idea of collecting water vapor from the air.
The air contains small amounts of bacteria. Water vapor and raindrops have this bacteria in them, too. But it’s in tiny amounts that won’t hurt you if you stick your tongue out and catch a few rain drops. Even drinking a cup of rainwater probably wouldn’t be too bad for you. But if you collect atmospheric water over time, the container you hold the water in will begin to develop a slimy coating called a biofilm. This biofilm can quickly become unhealthy and make you sick. Killing the bacteria and destroying the biofilm is necessary to keep atmospherically collected water potable and the containers uncontaminated.
All naturally occurring bodies of water can have harmful bacteria in addition to other contaminants, which is why drinking untreated water from streams, rivers and lakes can make you sick. Many of these bacteria in biofilm are difficult or impossible to filter out of liquid water because they contaminate the filter and then can’t be removed. This is why potable water is often treated with chlorine; to kill pathogens in the water and prevent biofilm buildup. The problem with putting chlorine in potable water is that most of the chlorine has to be filtered out of the water before it’s drinkable again. Unfortunately, liquid water is the most difficult medium from which to remove most contaminants. Which means, if you are going to collect atmospheric water, it’s much easier to remove contaminants and bacteria while they are in the air vapor rather than after condensation.
That’s why we developed the SPAWG, Self-Powered Atmospheric Water Generator.
The SPAWG (rhymes with frog) contains the built in power generation needed to run an atmospheric still that will pull water vapor directly from the air. As the water vapor enters the machine, it is blasted with sterilizing UV radiation and then shocked like a lightning storm. This kills all organic material and oxidizes inorganic micro-contaminants which are filtered out. The purified water vapor then travels into the condensation chamber where it is converted into liquid water which is then sent to additional filtration and treatment steps.
The base model is capable of producing five to eight gallons of pure liquid drinking water per day in normal relative humidity. It has an onboard storage capability for water generated in excess of daily usage. And the entire unit fits on a car-sized trailer that can be easily moved to other locations. The produced water can be connected to a house, cabin, RV or shelter and it can be used as a standalone source of water in any type of remote off-grid location. The proprietary patent-pending onboard filtration and decontamination system is so powerful it can produce pure clean water from air that is not clean or pure. Airborne dust, dirt, bacteria, heavy metal particles like mercury, elemental salts, ash, soot, smoke and even chemicals like chlorine and organic hydrocarbons are all effectively destroyed and completely removed. Nothing can get past the decontamination system except pure water.
This unit can even produce several gallons of drinkable water per day in dry desert conditions.
The only requirement is sun and air.
