There is always water in the atmosphere. Clouds are, of course, the most visible manifestation of atmospheric water, but even clear air contains water—water in particles that are too small to be seen. One estimate of the volume of water in the atmosphere at any one time is about 3,100 cubic miles (mi³) or 12,900 cubic kilometers (km³). That may sound like a lot, but it is only about 0.001 percent of the total Earth's water volume of about 332,500,000 mi³ (1,385,000,000 km³). If all of the water in the atmosphere rained down at once, it would only cover the ground to a depth of 2.5 centimeters, about 1 inch. http://ga.water.usgs.gov/edu/watercycleatmosphere.html

• Max Water Desal The core principle is to pump seawater inland in such a way that distillation occurs during movement of the water. As the seawater becomes concentrated it returns to the sea or to a mineral processing plant, flow rates being regulated to maintain salt concentration below 17 g % in the system to prevent the accumulation of precipitated minerals.
  
• Max Whisson's Gust Water Trap Apparatus The Whisson vertical windmill cools the air passing through the whirling blades. As it does so, a proprietary process collects condensate, yielding fresh water from the air. The water trap apparatus can generate useful resource for consumption.
