Default Bigger RFI threat than BPL, IBOC?

Greetings;


Thanks for bringing this to our attention. If the energy stays near the
coil, how would it interfere with HF?


How are you going to get it to "stay near the coil" and still couple
any energy into the other end? In fact, at that frequency it is
impossible to get much efficiency, so that majority of the RF will be
radiated. According to the article, the made id a whole six fet. To
double that distance, they would have to put four times the energy into
the system. There is enough inefficient crap on the market already. If
that idiot can't remember to charge his cell phone, then he doesn't need
it. If he's that absent minded, he shouldn't be allowed to drive, or
maybe be allowed out of his house.


Lets see my little Braun {Electric} Toothbrush already
uses Inductive Coupling {Wireless} to Charge the
Toothbrush while it is in the Cradle - Don't know the
Frequency but it is a no-contact re-powering system
for Battery run devices.

All this system does is up's the Frequency and extends
"The Gap" plus allows Power as you use it without an
Internal Battery. But at 40% Power Transfer Efficiency
a 60 Watt Light Bulb whould require 150 Watts of Source
Energy to power it. That's 150 Watts of ERP being
Generated within a House or Business : Even with only
a 10% Usage Factor thats a lot of RFI for a Nation Wide
deployment of this system.
