Outdoors air conditioning

Years ago we were in Palm Springs and it was really really hot. However it was made quite pleasant to sit outside by the outdoors air conditioning. 

This was basically a fine mist of water sprayed in to the air and this vapourising cools the air around it.

This system isn't quite right as the water droplets are a bit too big which means they are managing to reach the ground and make it wet. It is a good start though. We just need to find a more expensive example with metal nozzles instead of the plastic ones. This is going to be great in the mean time.
