That damn thing was so strong, our radio instructor told a story of a
guy who built flashlights which could be WABC-powered. How's that
possible, you may ask? A simple diode circuit to turn radio frequency
energy into low-level current to power a flashlight bulb if you're
close enough to the transmitter.
There are several, possibly apocryphal, reports of people using
power extracted from high-power transmitters to provide free
electricity, and being prosecuted for doing so (the offence of
Theft of Electricity is genuine, though usually used in cases
where people have bypassed their meter or used an outlet
belonging to someone else); see for example

Whether one could extract sufficient power to work filament lamps
or other equipment is dubious, but it is certainly possible to
use RF fields to power flourescent tubes.
