Abstract
A method for suppressing the formation of ice in natural or man-made bodies of water such as lakes, rivers, sounds, straits, bays, shipping canals, shipping locks, harbors, and the like. The method is particularly useful in areas where ice breakers or the like cannot be efficiently operated. The method provides for direct replacement of heat lost to the atmosphere during the winter season by the use of heat transfer means such as permanent heat transfer apparatus located in and/or adjacent the sides of canals or rivers to prevent natural bridging of ice formations in the same or by the use of a traveling heat exchanger disposed in a barge, scow and the like.
