RESEARCH EXPLAINER / 24 OCTOBER 2026

Collecting fog and clearing fog are different achievements.

Fog holds liquid water in suspended droplets. A collector can intercept some of those droplets and drain them into a reservoir. That does not, on its own, establish that visibility has improved across a road, runway or landscape.

The mechanism

Water collection asks how much liquid is recovered under defined airflow and droplet conditions. Visibility asks how strongly the remaining droplets attenuate light along a specified path. These measurements describe related but different outcomes.

The published foundation

Published research has investigated electrically driven droplet collection. The Weatherhill brief uses that literature as a starting point for defining collection experiments and their controls, while keeping visibility as a separate endpoint.

The next question

The proposed record should include flow, humidity, droplet conditions, recovered water and electrical consumption. A visibility claim additionally requires an optical measurement with a defined path and comparison. The practical opportunity becomes clearer when each result answers one precise question.
