Abstract
Delivery of pelletized carbon dioxide (dry ice) to a target material from a distance, by projection, spraying, or aerial dropping the pelletized carbon dioxide onto the target material using gravity. Delivery may be made by a mobile apparatus. The types of target material with which the present invention is designed to apply may include, e.g., hydrocarbon material, hazardous material, burning material, and the like. The carbon dioxide may be pelletized to diameters in a size range of about 3 mm to 100 mm.
