Back at about the same time the BBC had (and still has) a powerful
transmitter on 200khz (now198) a local farmer who lived close to the station built a large tuning coil in the loft and lit his house using fluorescent tubes. He was successfully prosecuted for stealing electricity or something similar. Alec "javawizard" wrote in message ... In the 1920's a radio station in Schenectady, NY built a powerful transmitter. In those days before FCC regulations, not knowing just how big to make a transmitter in order for the signal to be received some distance away, the station set up to broadcast at 500,000 watts. It requires about one watt to be received four blocks away. A cell phone is three watts. This station broadcast at such tremendous power that they could be heard around the world. People in New York didn't even need radios. They could sometimes hear voices in their furnaces and coming off chain-link fences. Light bulbs lit up in people's houses even if they were switched off. - from www.clip-text.com |

Here is another take on the story: =============QUOTED MATERIAL========================================= From: "Steve Maudsley" Message-ID: Newsgroups: uk.legal Subject: Theft of electricity? Date: Mon, 23 Feb 2004 18:12:00 -0000 NNTP-Posting-Host: 81.103.216.21 NNTP-Posting-Date: Mon, 23 Feb 2004 18:14:40 GMT Organization: Virgin Net Usenet Service "Jeff" wrote in message ... But a transformer still involves a direct physical connection to the mains via the primary. The primary is consuming current via its physical connection, whatever may happen to the current after it has entered the primary. The power line *is the primary*!! It is just that the secondary is separated from it by a larger distance than normal. In any case I believe that someone was prosecuted some years ago for doing what it being suggested. I do recall a story about 30 years ago (possibly apocryphal) about a farmer who lived on the UK side of the Radio Luxemburg transmitter and powered his cattle shed from the radio waves, and was prosecuted. Radio Luxemburg had some sort of phased array and the cows electrical use disrupted the beam. ================END OF QUOTED MATERIAL==================================== Michael |

In order to use the electrical current/field, all one had to do was ground one side/wire to Earth. The other side or wire would be the receptor/antenna for lack of a better term. I'm not a technical person but I think I have the basic premise right. |

I'm not a technical person but I think I have the basic premise right. No. It wasn't DC, since DC is direct current. That was Edison who would have needed a power plant every half mile or so. Tesla was hyping "Broadcast power" which was lossy broadband RF power that would wipe out most of the usable RF spectrum. Due to the 'Inverse Square Law', it was impractical, and always will be. Tesla was responsible for AC power distribution, which ****ed Edison off. -- http://improve-usenet.org/index.html aioe.org, Goggle Groups, and Web TV users must request to be white listed, or I will not see your messages. If you have broadband, your ISP may have a NNTP news server included in your account: http://www.usenettools.net/ISP.htm There are two kinds of people on this earth: The crazy, and the insane. The first sign of insanity is denying that you're crazy. |

Edison favored DC for some reason and Tesla quit and went to work for Westinghouse. When the electric chair was proposed Edison did everything he could to discredit it because it used Tesla's AC power. Dave N |

FWIW, the Wikipedia article: http://en.wikipedia.org/wiki/Wireless_energy_transfer describes some of Tesla's ideas and also has a list of references to more recent wireless energy distribution schemes.

Now whether this is true or not is another matter. It seems to me that a resonant structure to capture energy would re-radiate so I can't see where such a null would come from, the wavelength is long so the path difference between the main tx and the re-radiator would make such a phase shift difficult to achieve. -- Brian |
