The fog harp is an advancement of existing mesh-based fog harvesting technology.

What sets the fog harp apart?

Conventional meshes collect fog well, but they allow too much fog to pass through uncollected. If they are too densely woven, they are prone to loss from evaporation, as droplets get caught on horizontal threads or. The fog harp only has vertical wires, allowing droplets to quickly fall from gravity, unimpeded by horizontal cross wires or fibers.
