Isn't this somewhat similar to the magnetic plug the new Macs use (and subsequently catch fire from) ? My main worry with inductance power is the very fact that it isn't hard-wired. Doesn't that mean you could create varying levels of resistance by affecting the distance between the transformers ? If you were to put a thin object between the two devices, would that make the circuit "work harder" to overcome the distance, generating waste heat either in the gap or in the emitter circuitry as the capacitive circuit tries to compensate for the power loss ? My knowledge of electronics is limited to empirical observations so be gentle! :)

Um, no. What are you talking about? The magnet provides a mechanical attachment, not an electrical one.
