Since i don't know physics i lake the basics for this question.<br>
<br>
As i understood from googling it is possible to get some power from
high power radio signals (1).<br>
Since i believe that radio broadcasting (AM) allow power transfer i ask
about other types of transmittance.<br>
I guess this will be true only for analog transition since i believe
that with digital some one will lower the amount of power for the
signal, is my guess correct ? <br>
<br>
After reading part of a book in a close area i start to understand that
it is a myth to use Wi-Fi as a power generation , the question about
Terrestrial and Wi-Max still exists.<br>

But i guess using systems in other ways then they had been designed is
a bug that not only i posses.
I heard a lot about wireless power transition , while I heard about
products that provide close distant power transmitting (1) what about
using public wifi in my area ?
I met many people that "heard" about some one that know some one that
has access to device that uses radio signal to transfer low amount of
power in short ranges.
As i googled about it i guess it can be done using rectennas but only
in close range to _High_ power radio transmitters (2)
My question is it possible to be done with small radio signal
equipment as Wi-Max and Wi-Fi ,Perhaps even with the new terrestrial
transitions.
Do any one have links to this kind of devices ?
