1. A system for melting interfacial ice, comprising:

  • a first electrode embedded into or coated onto an object to be protected from ice formation;

    a second electrode, the first electrode and the second electrode defining an interelectrode space between the first electrode and the second electrode, the first electrode and the second electrode defining an interelectrode distance that separates the first electrode and the second electrode;

    an electrical insulator located in the interelectrode space, wherein the insulator comprises a nonconductive rubber windshield wipe blade; and

    an AC power source for providing an AC voltage across the first and second electrodes having a frequency greater than 1000 Hz and less than 300 KHz wherein the interfacial ice is melted upon application of the AC voltage.
