[OT] Power over radio is it a true thing or just a myth ?

[Boris shtrasman]

Sorry for the OT ,


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 ?
