How Wireless Electricity Works: Step One
Graham Murdoch
A circuit [A] attached to the wall socket converts the standard 60-hertz current to 10 megahertz and feeds it to the transmitting coil [B]. The oscillating current inside the transmitting coil causes the coil to emit a 10-megahertz magnetic field.
The receiving coil [C] has the exact same dimensions as the sending coil and thus resonates at the same frequency and, in a process called magnetic induction, picks up the energy of the first coil's magnetic field.
If it was really this easy to "Transmit" electricity, then why don't we just use existing radio waves (hmm, maybe even static noise) to do the same thing?
Besides, there is the fundamental law of energy to make use: However much power you would need to light that bulb you would have to put into radiation (erm, radio/electromagnetic). Aren't there laws and safety regulations against that?
"If it was really this easy to "Transmit" electricity, then why don't we just use existing radio waves (hmm, maybe even static noise) to do the same thing?"
Because transmitting electricity through electromagnetic waves is inefficient, electromagnetic waves disperses when they propagate through the air loses some of the energy
It's a nice invention..
I am eagerly waiting for that to come..

imagine a 2 Kwatt consumer connected like this and try crossing the 10 Megahertz beam.Talk to me later!!!

Thank you very much for this information. I like this site
Thanks matthew. Apparently
