1. A wireless power system, comprising:

  • a signal generator, having a connection to a source of power, and which creates a substantially unmodulated signal at a first frequency; and

    a transmitting high-Q resonator, generating a magnetic field having said first frequency and based on power created by said signal generator;

    a receiving high-Q resonator, receiving a magnetic power signal created by said transmitting resonator, said receiving resonator being a distance greater than 1 m spaced from said transmitting resonator, anda load receiving part, receiving power from said receiving resonator;

    wherein a transfer efficiency between said transmitting resonator and said receiving resonator is greater than 25% at 1 m of distance between said transmitting resonator and said receiving resonator.
