1. A system, comprising:

  • a first resonator coupled to an energy source generating an oscillating near field region; and

    a second resonator optionally coupled to an energy drain and moving freely within the near field region of the first resonator,wherein the first resonator and the second resonator are coupled to transfer electromagnetic energy from said first resonator to said second resonator as the second resonator moves freely within the near field region,and where the region includes distances greater than the characteristic size of the smaller of the first resonator and the second resonator.
