Some points raised by others:
And what happens as soon as you start drawing power from a resonant circuit?
Things only resonate sharply because the energy has nowhere else to go.
Change the load of a resonant circuit and things go to hell in a handbasket. I'm having trouble dealing with the resilience of such a system in real world load scenarios.
I know the system works, because:
I know who the investors are
I know who the inventor is
I did not see system working but I did see names. LOL.
No first hand information?!! Do you also blindly believe used car salespeople and software salespeople? Because until there are results that have been verified by an independent third party, then you are smiling and nodding to someone who says "Trust me!".
You made my point, its not really magic, its a known principle of electromagnetism, to use the earth as the guide surface, just like the EMF traveling along a conductor.
To steal the power, you have to have the ability to craft a circuit that has the tuning tolerances to 0.00000001 Hz. Your car radio goes out 1 decimal place...
First you'd have to build a receiver capable of receiving a guided wave, then give it the precision to tune to 8 or more decimal points to resonate the circuit. Good luck building the receiver to those specifications ...
It seems somewhat obvious to me that the same constraints would apply in delivering power to an authorised recipient.
... and better luck finding the broadcast frequency.
What? Is a spectrum analyser no good?
I've done some small experiments in wireless power transfer systems myself. One problem is what I call "inadvertent reception" where things become energized that you don't necessarily want to be. If receiver tuning needs to be as sharp as all that, maybe inadvertent reception is less of a problem.
This is a real Pandora's Box, IMHO.
There have been claims that mobile phone transmissions can create sparks in any suitably arranged conductive bodies that are close enough. While the power levels are low and the critical dimensions are highly improbable and, that as a result, it is highly unlikely to be encountered, it
is theoretically possible. Bump up the power a few orders of magnitude and the range extends far and wide - so who knows what might just happen to "tune in".
Another aspect of this is: What effect will dumping such large amounts of power into the environment cause? Will the forests absorb some - and to what effect? What about the fleshy bags of salty water and tissue walking around? The ionosphere? The magnetosphere? Please don't say human efforts cannot compare with nature's might. Wood fires weren't a big problem for millenia, but when the Industrial Revolution came to town, carbon emissions started on a perilous trend.
Call me an alarmist if you must - but these are just questions. Questions which I believe deserve considered and researched answers.
