What is wellcomb?

wellcomb is a field-testing project exploring whether simple, rigid geometries can be used to harvest fog as a low-cost, supplementary water source.

The project focuses on testing different surface forms - including comb-like geometries - under real wind and fog conditions to understand performance, robustness, and cost before anything is scaled or deployed.

Is this a finished product?

No.

The current work is a test piece, not a finished solution.

The goal is to generate evidence about what works reliably in real conditions, not to present a final design or make claims about deployment yet.

What is fog harvesting?

Fog harvesting is a way of collecting water directly from low cloud or fog. As moist air moves through a structure, droplets collide with surfaces, merge into larger drops, and drain downward under gravity into a container.

Fog harvesting is passive - it relies on wind and gravity rather than external energy.

Where does fog harvesting work?

Fog harvesting works best in places with:

• frequent fog or low cloud
• consistent airflow
• terrain that forces moist air upward (such as hills or ridges)

It does not work everywhere. Flat landscapes, still air, or infrequent fog can make it ineffective.
