Research prototype

H-two-O — an atmospheric-water research prototype

Pulling water out of thin air — politely, and with the ground's help.

Research prototype. Not a validated potable-water product. Do not drink the results (yet).

This site will eventually live at htwo.buenatura.org.

3D model

Drag to orbit, scroll or pinch to zoom, right-drag to pan. Placeholder geometry until the real v3 model lands.

Why / reasoning

  • Contained, ground-cooled

    An atmospheric-water prototype that leans on ground cooling — not a compressor-heavy appliance pitch.

  • Small solar, small brain

    A small solar battery runs the pump, the fan, and a reused Android phone acting as controller and display.

  • Sense, then water

    A local relative-humidity sensor, and irrigation triggered by tank level.

  • Measure first, claim later

    Yield and drinking-water safety are unverified. Numbers come after measurement, not before.

Process so far

  1. v0

    CAD concept v0. Placeholder.

  2. v1

    Intake-hood work. Placeholder.

  3. v2

    Refinements. Placeholder.

  4. v3active

    Contained unit — current active design.

  5. v4cancelled

    Started and cancelled. v3 remains the working model.

  6. Nextnext

    Measurement, not more CAD.
