ALLFROMAIR® TERRA² Technical Addendum 7 — Wind-Assisted Aeraulic Drive, Regenerative Electromagnetic Braking, and Goldilocks Site-Selection Framework

This Addendum to the ALLFROMAIR® TERRA² Tri-Generation Platform discloses four novel extensions enabling wind-assisted and fully fan-free operation. (1) Wind-Assisted Aeraulic Drive: ambient wind replaces mechanical EC-fan work through natural pressure-driven ventilation in the low-resistance Anticubic U-Channel at wind speeds ≥ 2.5 m/s. (2) Regenerative Electromagnetic Braking: fan motor inverters operate as electromagnetic retarders, controlling channel air velocity to ±0.1 m/s while recovering 1.2–4.2 kW at 4–6 m/s wind to power sensors and AI-CORE™ control systems. (3) Marine-Grade Self-Locking Storm Dampers: worm-gear actuators with self-locking geometry maintain damper position at 0 W holding power against full storm load. (4) Goldilocks Site-Selection Framework: a systematic siting methodology combining the 1 km passive salt-filtration rule, cold deep-water intake (4°C), topographic wind-break exploitation, and coastal wind-corridor statistics. ECO 1 (compressor off, no SVRU circuits) and ECO 2 (compressor off, SVRU1 active with 4°C deep seawater) operating modes are formally defined. ECO 2 yields ~90,000 L/day at Gotland conditions (validated, Open.pdf Case D) and ~200,000 L/day at tropical coastal conditions with cold upwelling. The framework extends to tropical and desert coastal sites served by cold upwelling currents (Benguela, Humboldt, California Current). All innovations are additive to the existing TERRA² architecture; no new materials or hardware modifications are required. This publication establishes prior art under the pending Swedish patent applications SE 2530864-4, SE 2530806-5, SE 2530843-8, and SE 2530868-5. Zenodo keywords:
