Abstract

This defensive publication discloses a passive, megalitre-class atmospheric water generator (AWG) architecture in which humid coastal air is drawn through an array of five parallel bedrock tunnels, condensed on the cool rock walls, and discharged through a mountain-slope-integrated inclined solar chimney. The rock itself is used as the primary condenser, the bedrock tunnels are dimensioned at the diameter that matches standard utility-scale tunnel-boring-machine (TBM) production, and the inclined solar chimney is routed along the natural face of the inland ridge so that the bedrock carries all structural loads and the chimney's own upper surface acts as a combined solar collector.

The design is deliberately honest about what it delivers. In a Nordic or continental-temperate climate the five-tunnel footprint yields approximately 0.78–0.93 million litres per day at realistic airflow rates and does not reliably reach one million litres per day. At Mediterranean-class maritime coasts the same footprint delivers approximately 1.16 million litres per day, and at tropical coasts approximately 1.98 million litres per day. The nameplate 'megalitre-class' label in this publication refers to this full envelope, not to a single universal figure.

Three elements that the present plant relies on — the Goldilocks site-selection framework, the Wind-Assisted Aeraulic Drive, and the tiered purpose-graded water-treatment distribution — are NOT claimed as new in this disclosure. They were established by the author as prior art in TERRA² Technical Addendum 7 (Goldilocks §8 and Wind-Assisted Aeraulic Drive §6) and the TERRA² Defensive Publication §5.5 (water-grade tiering), and are referenced here, not re-claimed. The present publication adds the bedrock-tunnel and inclined-solar-chimney architecture that uses all three of those frameworks.

The architecture is disclosed in full here to establish it as prior art. No patent is sought. The author retains authorship, attribution, and a perpetual, worldwide right to practice the disclosed technology, and grants the same rights to all third parties under the terms of CC BY-SA 4.0.

The disclosure is positioned as a civilisation-scale complement to the author's existing ALLFROMAIR® portfolio, in particular the TERRA² / Three-Stage-Rocket platform (Swedish patent applications SE 2530864-4, SE 2530799-2, SE 2530806-5, SE 2530843-8, SE 2530868-5) and its associated defensive publications on TD Commons and Zenodo.
