This article compares two systems for wireless energy transfer - one is by WiTricity and another is Bombardier PRIMOVE. I've read their descriptions thoroughly - to me they both look like resonant inductive coupling systems.
Yet the article says that WiTricity system uses resonance rather than electromagnetic induction and is more efficient because of that.
Is such comparison valid? Are there indeed "induction" and "resonance" wireless transfer systems or is it just the same thing being marketed differently?
