Wireless energy transfer dates back to Tesla. It uses LF/VLF radio waves for the purpose. Since there are high powered transmitters involved, the risk of health effects (allthough not proven?) is possible.
I was thinking of another way and I would like your oppinion about it.
It is as simple as this: A permanent magnet, spins by the use of a local motor, creating a rotating magnetic field; this is the transmitter. A remote coil picks up this rotating magnetic field and converts it to AC; this is the receiver.
Very simple, like an "open" motor generator, isn't it? And there are no considered health effects from a rotating magnetic field as far as I know (patients use MRIs as a safe alternative to the X-ray machines).
Searching on this idea on the net, to see if someone else have thought it, I found that a university has used what they called "magnetic gears" to remotely charge an ellectric car. The car parks above a rotating magnet, which causes another magnet inside the car to rotate at the same speed and this rotates an internal car motor. This is basically an ingenious magnetic gear indeed.
My idea does not use a second magnet, thus minimising moveable parts (but more inefficient though), it just uses a coil to directly pick up this rotating magnetic field.
Just for fun, how does it sound to you? Have you found anything similar published before, after all it is a very simple idea for someone not to have thought it already.
