Abstract: A snowmaker mounting structure is described useful for attaching a snowmaking apparatus used at ski resort areas to a ski lift tower. The structure includes a generally horizontally extending boom having one end attached to an upper portion of the ski lift tower and an extending end having a snowmaker attached thereto. Control over the region of ski slopes being covered with artifically produced snow is provided by rotatably mounting the snowmaker to the end of the boom by employing a generally vertically oriented collar through which a central tubular post is inserted and rotatable therein. The water supply is conducted to one end of the post and a pair of turning cables are connected to the post which, through tension being applied to either one of the cables, causes the snowmaker to be rotated with the collar. This invention eliminates the necessity of providing a separate snowmaker mounting tower.

Abstract: Cooling water at 39.degree. F is made available at low cost all year round by erecting towers in farmer's fields and spraying the water in the air around the towers to cool the water during the winter. The cooled water is collected and stored in a lake. During the summer the same towers and water spraying system is used to act as a permanent irrigation system with the water from the lake sprayed when needed on the farmer's crops. Since the users of the cold water from the lake for cooling water have to and can easily afford to pay for the whole system, which includes a very good drainage system, farmers will greatly profit and therefore greatly favor the installation of such a system on their farms.
