Mister to Cool A Large Outdoor Area

I thought this was a pretty interesting idea to cool a large outdoor area.  Its is intended to cool cows, but would probably be appreciated by other hot mammals as well -- including two legged ones. 

 

I'm sure a PV powered version could be designed.

 

It is from Owenlea Holsteins -- Pasture Water Systems

A Pasture Mist Generator - Essential Part of the Water System

Last summer we were visiting dairy farms in southern Ohio where the temperature was 106F or 41.1C with 100% humidity. We drove by at least six dairy farms with dead cows pulled out in front of the barn. Presumably, a few farmers would have had the common sense to pull them out behind the barn, so there were probably many more.

Back at Owenlea Farm, on the same day, son Blake was in charge of our herd. He had 104F that day but managed to keep our cows fairly cool. Our cows were outside all day with no shade but he was able to keep them moist and there was some breeze. The crude drawing below may give you some idea of how our mist generator operates. With the help of the breeze, we were able to mist an area about 30 feet X 200 feet.
