God’s Invisible Spring: Build Your Own Solar-Powered Machine That Harvests Water From the Air
There may be more water surrounding you than you realize.
Even on a clear day, the air can hold enormous amounts of invisible moisture. God’s Invisible Spring shows you how to capture some of that moisture and turn it into a practical backup water source using a familiar appliance, solar power, and a carefully designed collection and treatment system.
At the center of the book is a complete solar-powered atmospheric water harvesting system built around a standard dehumidifier. Humid air is drawn across a cold coil, moisture condenses into liquid water, and the collected condensate is then moved through filtration, treatment, and sanitary storage.
Instead of depending entirely on grid electricity, the system can be powered by solar panels, battery storage, and a pure-sine inverter—giving you another potential source of water when conventional systems are unavailable.
Inside God’s Invisible Spring, you'll discover:
-
How Atmospheric Water Harvesting Works – Understand the simple condensation process that pulls water already present in the air
-
How to Test Your Climate First – Determine whether your temperature and humidity make atmospheric harvesting worthwhile before investing in the complete build
-
How to Choose the Right Dehumidifier – Learn what to look for in a dependable donor machine
-
How to Build the Protective Housing – Create a weather-resistant, serviceable enclosure without choking off critical airflow
-
How to Convert a Dehumidifier Into a Water Harvester – Collect and drain condensate while keeping the original refrigeration system intact
-
How to Build the Solar Power System – Learn the relationship between the solar array, charge controller, battery, inverter, disconnects, and electrical protection
-
How to Capture and Move the Water – Properly route condensate into a separate raw-water collection system
-
How to Filter, Treat & Store It – Build a treatment chain using sediment filtration, activated carbon, UV treatment, and sanitary storage
-
How to Start and Test the Finished System – Follow a step-by-step commissioning process before depending on your machine
-
How to Measure Your Actual Water Production – Track temperature, humidity, energy consumption, runtime, and water yield instead of relying on unrealistic gallon promises
-
How to Troubleshoot Common Problems – Diagnose low output, drainage problems, inverter trips, icing, treatment issues, and more
-
How to Maintain the System for the Long Haul – Follow practical cleaning, sanitation, filter replacement, inspection, and seasonal maintenance routines
The book walks you through the complete system from humid air to treated storage, with detailed illustrations, diagrams, component breakdowns, operating procedures, worksheets, troubleshooting charts, and maintenance guidance.
You'll also discover ways to improve and expand the system over time, including humidity-based controls, additional storage, energy monitoring, freeze protection, and increased treatment capacity.
And as an additional emergency option, the book includes plans for the $12 Emergency Sky Catcher—a simple passive collector designed to experiment with capturing moisture from fog, mist, and heavy dew using inexpensive materials.
God’s Invisible Spring isn't about promising an endless supply of free water. It's about adding another layer of independence to your family's water plan.
When the grid fails, pumps stop, or your normal water supply becomes uncertain, knowing how to harvest some of the moisture already moving through the air could give you one more valuable source to fall back on.
Build it. Test it. Learn what your property can produce. And become less dependent on a single source for one of life's most important necessities—water.
