Using self-resonant coils in a strongly coupled regime, we experimentally demonstrated efficient
non radiative power transfer over distances up to 8 times the radius of the coils. We were able
to transfer 60 watts with ~40% efficiency over distances in excess of 2 meters. We present a
quantitative model describing the power transfer, which matches the experimental results to within
5%. We discuss the practical applicability of this system and suggest directions for further study.
