An object of the invention is to provide a break detection method capable of lessening a delay of motor power line break detection. End-users are coupled to a broadband customer access network. While maintaining the top of the melted silicon S\u2032 in a melted state, the melted silicon S\u2032 is solidified sequentially from the bottom in the cooled water-cooled copper crucible 200. They can include protected cavities that contain utility equipment and supplies, and they can include conduits from these cavities that can be extended upward through one or more legs of a tower. The granted request for information is received during the real time communication.
