Abstract
A fog generator comprises a duct which is preferably vertical and very tall, an air mover for moving air down through the duct, an air director which includes a spout to direct the air emerging from the duct in a substantially horizontal stream in a chosen direction away from the duct and a fog generator which generates a fog into the moving air preferably after the air has left the spout. The spout is preferably rotatable in a horizontal plane. The invention enables a generated fog to be placed where required by the air stream in which it is entrained rather than relying on natural wind drift.
