Nithya, this is VERY interesting info. Like you said, I wonder what can be - ve effects of this. Like current flowing thru grids produce magnetic field around it that is known to play with human brain, but not sure if this will be applicable here. Wonder how the current flows here in the first place.

To be very honest.. it all sounds very scary! If every house were to have at least one transmitter, I could only imagine the amount of electrical and magnetic fields spiraling through the air.

Personally, I could live with the wires to avoid this mess!

As for the exact process of WiTricity (as its popularly being called), I’m a little unsure. The physics is all way over my head. But i could give you the search words that could help.
Look up Resonant Induction and Evanescent Wave Coupling.

Thanks Nithya, I will check it out.
