OT Killing your wife
I was watching a BBC show called "Light Fantastic" Part of the show
shows how Edison was trying to build a market for electricity. It showed many appliances such as the vacuum cleaner, kitchen mixer and the phonograph. They then showed a logo sign that read.........Don't kill your wife with work! Let electricity do it. |

Jon Edison and Tesla were inventors. Westinghouse was a con artist marketer who porked Tesla. DC makes a lot more sense in some cases. They just didn't have the technology back then. Ask yourself why so many new high power/high voltage long distance lines are DC. |

The superiority of AC over DC for power transmission is due solely to these two facts: a) the higher the voltage, the lower the losses in transmission. b) AC can drive a transformer, but DC cannot. Thus, it's possible to step AC voltage up arbitrarily high for transmission to minimize losses, then step it back down for distribution. This can't be done with DC. |

Ask yourself why so many new high power/high voltage long distance lines are DC. My guess is by using DC you won't have inductive coupling problems. The capacitive and inductive reactance would be minimized and perhaps impedance wouldn't be a big problem. You wouldn't have to worry about keeping the frequency of the power supplied right on 50/60 hz. I'm no rocket surgeon but there are things about AC power that can make it a pain in the butt to deal with sometimes. I know that the magnetic field of the Earth can induce current on long lines. Perhaps a mad scientist or angry engineer could chime in and explain it all. TDD |

W/ a passive transformer that's true but solid-state devices mean can now effectively build DC voltage step-up/down devices that couldn't (practically) before. AFAIK there aren't yet any long-distance DC grid transmission lines in the existing US grid but there are at least some on/in the planning (and maybe construction by now, been nearly 10(!!??!!) years since retired and had direct contact w/ the particular utilities involved) so not sure exact status. There are plans for some new lines from various large-scale wind farms and if they're ever built in all likelihood any lines from offshore wind will be DC. Back when still working, studies in EPRI indicated something otoo 100 miles was about the breakeven point between AC losses and the extra cost of DC installations for general transmission. For dedicated facilities it could be much shorter, say 10, maybe. -- |

Well, George Westinghouse was a strict capitalist, and was the one who gave him the job in the first place. While he did indeed profit immeasurably from the work of Nikola Tesla, the relative levels of fame and wealth possessed by Mr. Tesla at the time of his death were not the responsibility of Mr. Westinghouse. That doesn't mean I don't think Mr. Tesla deserved a better end to his life, mind you, but sometimes it happens that great men die deaths unbefitting their legacy. Jon |

If you don't count Tesla letting Westinghouse off the hook. http://flyingmoose.org/truthfic/tesla.htm The agreements between Westinghouse and Tesla called for the businessman to pay the inventor a royalty of two dollars and fifty cents - for every horsepower of AC equipment sold. Even a century ago, the royalties would be enough to make Tesla one of the wealthiest men in the world. (Were such royalties to be paid on equipment in use today, the royalties on AC generators alone would be worth more than seven and a half billion dollars.) ----- Like many geniuses Tesla wasn't playing with a full deck. The guy wanted to marry a pigeon. |

The guy wanted to marry a pigeon. And the complementary passage from your link above: "Westinghouse came to Tesla and described the situation. Tesla replied with these words: "Mr. Westinghouse, you have been my friend, you believed in me when others had no faith; you were brave enough to go ahead... when others lacked courage; you supported me when even your own engineers lacked vision... you have stood by me as a friend... "Here is your contract, and here is my contract. I will tear both of them to pieces, and you will no longer have any troubles from my royalties. Is that sufficient?"" Possibly not the most practical decision, but you can't blame Westinghouse for him doing it. Jon |
