Wireless Energy Transfer
« on: June 17, 2007, 02:55:06 AM »
Hello, this probably has nothing to do with overunity but I was wondering if anybody could help me.

My friend and I have started a project trying to power a load (led light or a usb device) without any use of conductivity (wires). This was recently achieved if anybody read about it on the news. So my friend and I thought about using coils wrapped in X turns (with primary and secondary sides separated over a small distance) and insert a ferrite magnet to improve the efficiency of the power transfer. This has already been achieved and they call it inductive charging but it is very inefficient with a safety hazard tagged on it.

In order to improve the efficiency of the wireless energy transfer over a certain distance (feet), resonance was added into the equation. W/ resonance, energy would not be radiating everywhere but contained within itself unless an object with the same resonant frequency was in range.

My question is how do you match the resonant frequency of the transmitting end with the receiving end. Adding an LC component into the equation?
And how do you build a self-resonant system?

I hope someone understands what I just typed.

Google:
Evanescent coupling
magnetic coupling
resonant inductive coupling

Glad to hear you have it figured out...

You'll have to pardon the lack of answers in this thread...
Right now most of our members are heavily involved in one or more projects,
but I'm currently trying to encourage more research in this direction. Stick
with it, and please post any info you can on your device efficiency, and any
other data you think will influence others to take a look at your design.

Thanks for coming here to share your progress,
~Dingus Mungus
