Pulse electro-thermal de-icing

Pulse electro-thermal de-icing (PETD) is a new method of ice removal and prevention that uses short pulses of electricity applied directly to an ice-material interface. PETD uses a thin, electrically-conductive film applied to the substrate. The film is then heated with a milliseconds-long pulse of electricity. Because only a micrometer-thin layer of ice is melted, PETD achieves nearly perfect efficiency even in extreme cold. Regular pulsing can keep surfaces consistently ice-free while maintaining low overall power consumption. Research is ongoing for the extensive applications of PETD such as de-icing of airplanes, ships, refrigeration systems, windshields, power lines, bridges and buildings, roads and walkways, and windmill turbines.
