I love stories like this. As the article shows, stealing very low frequency mains power (60Hz) this way is highly inefficient as practical considerations would reduce the coupling efficiency to ridiculously low levels. However, I do recall a method that was apparently 'much' more efficient (at least from a theoretical perspective). That said, it was still inefficient in absolute terms. Some decades ago I read a report that someone who lived very nearby to a Navy high power (~1MW) low-frequency RF transmitter used to communicate with submarines stole power by building a suitable antenna to pick up RF energy broadcast from the transmitter (I think he put the antenna coil in his roof but that may just be hearsay). Note: I used 'low frequency' twice here so I must clarify, the RF TX was indeed very low frequency by radio standards (needed to communicate through seawater) but it was still many times higher than mains frequency. Assuming the transmitter's frequency was somewhere between say 12kHz and 35kHz then it would be between ~200 and 500 times higher than mains frequency, thus coupling the energy would be that much easier. This combined with both an antenna especially built to radiate as well as having a proper ground counterpoise/earthing system would have provided the transmitting station's neighbor with a much better opportunity to steal power. The report was so long ago I've forgotten most of the pertinent details but it seems that the guy got caught because they discovered an unexpected notch in the antenna's radiation pattern. If I recall this happened in Florida sometime in the 1960s. Seems the guy powered all his fluorescent lights from the RF. Would someone with a much better recollection of the facts please clean up the details. Thanks.
