The Coolerado Cooler uses renewable, atmospheric energy to produce cold air.  Water is used as a fuel to tap into atmospheric energy.  In fact, other than a small amount of power for the controls, a fan is the only item that draws power in the Coolerado Cooler.

Renewable, atmospheric energy is contained in the air we breathe and is always around us.  Atmospheric cooling can be witnessed during a typical summer afternoon thunderstorm.  

Prior to a thunderstorm forming, the air and the ground are heated by radiation from the sun.  Through processes of radiation, conduction, convection and evaporation, a tremendous amount of energy in the form of heat is drawn from the ground to form clouds.  The clouds are formed by water condensation, and much of the energy created from this process is radiated into outer space.  Most of a thunderstorm's energy is a result of the condensation that forms the cloud. According to Encyclopedia Britannica:

If the quantity of water that is condensed in and subsequently precipitated from a cloud is known, then the total energy of a thunderstorm can be calculated. In an average thunderstorm, the energy released amounts to about 10,000,000 kilowatt-hours, which is equivalent to a 20-kiloton nuclear warhead. A large, severe thunderstorm might be 10 to 100 times more energetic.

After the clouds form and it begins to rain, the hot air below the clouds collides with the falling rainwater.  As the two come together, heat is transferred from the air into the rainwater.  It is this latent heat transfer that makes the air cooler after a rainstorm.

The Coolerado Cooler works to transfer heat from the inside to the outside of a building in much the same way.  You could say, ‘The Coolerado Cooler is a thunderstorm in a box.’

The natural perspiration process in our bodies also works in a similar fashion.  As our skin heats up, our bodies perspire and form small beads of moisture on the surface of our skin.  As warm air passes over our skin, the hot air collides with the moisture evaporating it from our skin.  Evaporation cools us to help keep our bodies at the proper temperature.

The Coolerado Cooler uses this same renewable atmospheric energy and latent heat transfer process to cool spaces and people.  However, evaporation occurs in a separate chamber and the cooling is transferred to the dry air stream that enters the building.  Hot, moist air is rejected to the outside where it will be dried and renewed through rain for use again and again.  Meanwhile, people have a cool, dry, comfortable environment in which to live and work.
