No, it said the device was able to produce .006 microWatts, that's .006 millionths of a watt.
No ! it said 6mW and that equals .006 Watts
in one case it was able to produce 6mW of power, at a distance of 3 or 4 kilometers from the tower.
Also keep in mind that it is rare for a broadcast station to transmit over 50 kW, so no matter how you work it that is all you could get out of it
Im sorry but your wrong about that , the amount of energy that these devices can generate using the radio waves is not bound by the amount of power that the broadcasting station used to produce the radio waves.
and leaving nothing for the communications receivers that it is aimed at.
radio broadcast are not aimed at anything specific.
you must be thinking of microwave.
http://en.wikipedia.org/wiki/Wardenclyffe_Tower it would do about the same thing as Tesla's wardenclyffe would have done long ago if he could have found a rich man who would have invested in it.
the rich man that financed wardenclyffe pictured above just couldnt figure out a way to charge people for the use of the energy they would be getting from the air.
