I don't want to sound ignorant but shouldn't i be worried about these electroc magnetic fields their using to transmit electricity through the air ??

I know you can develop tumors when living/regular exposure under high powered cables that have huge magnetic fields.

Technologies like this worry me :/ Sure it's nice and convenient but where is the health factor in all of this?

We are bombarded by earths magnetic field every second of our lives, and the sun's ultraviolet radiation. I for one am not worried about adding a little more magnetism to my diet. Taste like burning :eek:

no he didnt. his wireless energy transfer ideas failed because of inefficiency and lack of predictability

He invented alternating current too champ...made it possible to send electricity long distances with out loss, unlike direct current.

You're wrong Water does not have a resonance frequency. I used to think the same but is not necessary. You just need it hit it right. I can send you a PM with the RadioWaves book where I discovered it.

Molecules have a tendency to rotate at a certain EM frequency. Water molecules spin when hit with the microwave range of EM frequency, thus the spinning, which induces friction, which creates heat.
