The outlet pipe is buried to a depth of eleven feet and one foot above ground, with an air restrictor valve and wind turbine to pull the hot moist air through the system. The restrictor valve works in a similar way to the following experiment.
Blow air from your fully opened mouth onto you hand it will be warm.
Blow air from your mouth shaped as if you were to kiss someone it will be cool.
There are at least four heat exchange pipes and are a minimum of twenty feet long by 1.5 inch diameter . These heat exchange pipes and connection ends are slanted to allow the dew drops formed to run down into a collection tank which can be pump out by conventional means.
Method of operation
Hot moist air is drawn into the air intake pipe,, one foot above ground level seems to be the best position to capture the most moist air.
When the temperature inside the buried heat exchange pipes is below the dew point of the air flowing through them ,droplets of moisture of water will form and migrate to the collection tank. How much water is dependant on the amount of moisture in the air and the soil temperature and thermal properties. Moist soils tend to work to work the best however.
