1. A system for preventing ice formation on a surface of a solid object, comprising:

  • a first electrode disposed on the surface;

    a second electrode proximate to the first electrode;

    an interelectrode space separating the first and second electrodes, wherein the interelectrode space has a thickness not exceeding 3 mm; and

    an AC power source connected to the first and second electrodes, the power source capable of providing an AC voltage with sufficient power to prevent freezing of a liquid water layer in the interelectrode space.
