ALLFROMAIR® TERRA² Technical Addendum 7: Wind-Assisted Aeraulic Drive, Power-Inlet Pressure-Recovery Cowling, Reduced-Component ECO Operation & Goldilocks Site-Selection Framework

Version 7 is a voluntary physics correction. Versions 4 and 6 claimed that a passive ~600 m² sail cowling reduced the wind speed required for fan-free operation from approximately 16 m/s to 5 m/s by collecting wind kinetic power. A passive convergent cowling cannot achieve this: the driving pressure available to a passive intake is the free-stream dynamic pressure ½ρv², independent of capture area. Version 6 did not correct this — it made the erroneous threshold internally consistent. The error, the electromagnetic regeneration formulation, and several inconsistent psychrometric figures are corrected here. All superseded values are listed in Appendix A. Six disclosures: Wind-Assisted Aeraulic Drive by superposition of dynamic pressure on the system pressure balance; Power-Inlet Pressure-Recovery Cowling; Regenerative Electromagnetic Braking recovering surplus pressure above system resistance; Marine-Grade Self-Locking Storm Dampers; Reduced-Component ECO Configuration — omission of the compressor and of HX2, the reversible condenser/evaporator, moving fan-free operation from unreachable to attainable within the storm envelope; and the Goldilocks Site-Selection Framework. Every water production figure derives from a single stated rule and the Magnus equation and is reproducible by the reader. Where an input is not established, results are stated as bounded ranges. Published as open prior art. Patent pending: SE 2530864-4 · SE 2530806-5 · SE 2530843-8 · SE 2530868-5. Supersedes Addendum 7 v1–v6.
