It's all about magnitude.
To light up a florescent bulb or power a tiny little temperature sensor requires very little power.
To do anything that most people would consider "useful" (eg: run a car, charge a cell phone, etc) takes a great deal more power. There just isn't that much energy being "lost" out of power lines.

You'd need a pretty big collector mounted very near the lines in order to produce any useful light.
The guys in GA got a whole freaking milliwatt, using an antenna of unspecified size (a lot larger than a patio walkway lamp) from a transmitter whose sole purpose is to dump massive amounts of EMR into the surrounding environment, and was located 500 meters away.
