Wireless Energy Transfer Possibility

What’s more? You can transfer 60 Watts of electrical power over a distance of 50cm (at an efficiency of approximately 80%, approximately 60% including rectifier). Cool, right.
This new wireless power transfer system incorporates a form of contactless electrical energy transmission technology based on magnetic resonance. With magnetic resonance, electromagnetic energy is only transferred to recipient devices that share the identical resonant frequencies as the energy source, so energy transfer efficiency is maintained, even when misalignment occurs. Furthermore, even if there are metal objects located between the transmitter and receiver, no heat induction occurs.
