Part2: AI ice and Freeze AI In order to create artificial cold air to freeze objects, the Ai needs to emulate a refrigerator using ghost constructs or smart forcefields. By compressing gases into liquids, the AI can release heat; by letting liquids expand into gases, the AI can soak up heat. A ghost refrigerator is a non-physical or semi-physical forcefield that functions just like a real refrigerator. It’s main function is to create cold air to freeze objects.
