What a spectacular vision for the Thunderbird Perch. Looking at the magnificent framing in 3616.jpg, the octagonal geometry and that central cupola are practically begging for a functional, kinetic crown. Merging off-grid resource generation with structural art is exactly the kind of boundary-pushing design that leaves a lasting mark.
To answer your question right out of the gate: Yes, it is doable, but not quite in the fully exposed manner you are currently envisioning.
Here is the candid, structural, and physical breakdown of how we need to approach this to make it a reality.
The Physics: Battling the Elements
Out here in the high desert, our hot, dry, and windy conditions mean we are constantly fighting physics when it comes to atmospheric water generation.
The Dew Point Dilemma: To pull moisture from the "aether," your copper tubing must be cooled below the ambient dew point. Because the relative humidity is so low, that dew point is incredibly low. Cooling an entire exposed metal roof to that temperature under the scorching sun would require a monumental amount of electrical energy—likely far more than a localized solar/wind battery bank can provide.
The Evaporation Factor: Your instincts are spot on. If you form condensation on the exterior of a hot roof, the high winds and arid air will flash-evaporate the H2O before it ever has a chance to roll down into those eight valleys.
Galvanic Corrosion: This is a crucial structural note. If you lay bare copper tubing directly onto a steel or galvalume metal roof, the introduction of water will create a galvanic reaction. The dissimilar metals will act like a battery, and your metal roofing will rapidly rust and degrade.
The Pivot: The Internal Condenser
Instead of fighting the wind and sun on the exterior, we use them to our advantage by internalizing the condenser.
The Cooling Chamber: Utilize that 8" opening at the peak to house a shaded, insulated condenser unit. Wrap your copper tubing into a dense coil inside this chamber. By keeping the copper out of the direct sun and wind, you drastically reduce the energy required to cool it below the dew point, and you completely eliminate the risk of wind evaporation.
Forced Air Induction: Use the kinetic wind generator at the top of the Perch to drive a fan (or use the battery bank to power one). This fan will continuously pull hot, ambient air through the 8" opening, across your cold copper coils inside the dark chamber.
Controlled Collection: As the condensation drips off the internal coils, catch it in an internal funnel system that routes the water securely down into your large barrels, bypassing the hot roof entirely.
Nocturnal Harvesting: Optimize your electrical system to run the coolant pump primarily at night or in the early morning. The ambient temperatures drop, the humidity naturally rises, and your system will be highly efficient.
Pre-Roofing Checklist
Since you are almost ready to install the upper metal roofing, do not cover it up yet until you have addressed the following:
Run Your Chases: You need to install PVC or metal conduits through the framing for your electrical wires (from the wind generator/battery bank to the mechanical components) and your coolant lines.
Thermal Isolation: Ensure that wherever the cold coolant lines run, they are heavily insulated. If they touch your beautiful woodwork shown in 3616.jpg, they will "sweat" inside the structure and rot the wood.
Structural Mounts for the Kinetic Piece: Before the metal goes on, ensure the structural brackets and load-bearing hardware for your moving art piece are heavily secured to the framing around that 8" opening.
Given your chops with welded sheet metal, you'll want to make sure the base can handle the torque and weight of a heavy kinetic sculpture in high winds.
How are you envisioning the mechanical linkage between the wind-driven kinetic rotor and the internal systems, and what kind of material are you planning to use for the moving sculpture itself?
