Abstract
An ice making module includes a conductive ice tray having a bottom surface and a barrier coating on at least a portion of the conductive ice tray. An electrical circuit in electrical communication with the conductive ice tray includes a power source and a capacitor. A switch is configured to move between a charging position, wherein the capacitor stores an electrical charge, and a pulse position, wherein the capacitor releases the electrical charge. A conductive material disposed proximate the conductive ice tray is in selective electromagnetic communication with the conductive ice tray. The electrical charge released by the capacitor generates an induced electrical current through the conductive material and a repelling electromagnetic force between the conductive ice tray and the conductive material. A water dispensing mechanism disposes water into the conductive ice tray. A cooling apparatus decrease the temperature of the water in the conductive ice tray.
