It is fun to watch people experience Koolfog for the first time. There is a certain tangible nature to what we do. Koolfog is both visible and tactile and its benefit can be felt as well as translated to a return on investment. But unless you are an engineer you probably wouldn’t have a clue how it works.

The truth is that although the underlying physical principles are quite complex, the explanation is fairly straightforward. When water evaporates into air it cools the surrounding air and objects in contact with it.

To put this in perspective, here are some real-life examples of evaporative cooling:
- Sweat evaporating from your skin is your body’s natural defense against the heat. You only need a stiff breeze to remind you of that.
- Walk towards a lawn being watered in the summertime and you may notice that the air temperature is cooler as you approach.
- Jump out of a pool on a warm day and feel the chill.

This form of natural cooling was leveraged by the Persians thousands of years ago with the invention of the Bâdgir (windcatcher) whose architectural design utilized wind shafts to draw air across a water source and into structures. And Koolfog moves this strategy to cool outdoor settings.
