Conservatives during the last Congress accused Democrats of being anti-minority for blocking Brown, who is black; anti-women for blocking Owen, and anti-Catholic for blocking Pryor." http://www.cnn.com/2005/POLITICS/04/21/filibuster.fight.ap/index.html \_ Because it couldn't be that they're anti-psycho.. |

4/20 Why doesn't someone stick solar cells on hybrid cars? \_ I don't think hybrids have such big batteries... Why add an expensive array of solar cells when the gas engine charges the batteries just fine? \_ Plus it adds weight, and maybe distorts the car's aerodynamic shape which increases drag. \_ Photovoltaic cells don't generate very much. The surface area of a hybrid might provide enough to run the CD player on a sunny day. \_ A house-sized system can generate a few kW on a good day. A single horsepower is about 0.75kW. \_ You mean a few kWH on a good day? I was producing over 10 KWH a day with just a 3.3KW system, and my dad has a 6KW system on his house that produces I think approx 20 KwH per day ... He pays zero per year for his electricity, only a small bit for being connected to the grid. But for a car it wou'dn't work, ordinary gasoline cars need almost an order of magnitude more power than a house. This is why oil is so nice and why substitutes are hard without drastically cutting down the power requirements. \_ How much do the 3.3kW and the 6kW systems cost? \_ I'm putting in a 3.3kW system; after rebates, it comes out to about $18K. -tom \_ No, I mean a few kW will be generated on a good day. If you generated 10kWH in say 8 hours of usable sun that means you only averaged 1.25kW. If you were generating the full 3.3kW for 8 hours you would have generated 26.4kWH. I talked about kW, not kWH because kW, like hp is a unit of power, and is applicable to the way people think about cars. \_ because the drag and weight of the solar sells wouldn't make up for the energy the generate? Not to mention the weight. Besides, hybrid cars aren't about electric power, they're about 'more efficient' gas power. It's silly to think of them as some some panacea for energy savings and the environment, because ultimately they're still just burning gasoline. |

4/21 Buh, duh, huh? http://www.dw-world.de/dw/article/0,1564,1559253,00.html France Backs China on Taiwan \_ The French gov't makes me feel icky. \-C HITCHENS had a great comment about J CHIRAC: "a man, like the banker in Flaubert's Sentimental Education, 'so corrupt that he would willingly pay for the pleasure of selling himself".' --psb \_ It's wrong for France to back the Anti-Secession Law, especially when France is going against the countervailing current of world opinion that the law was unnecessary and increased tensions. As for the EU trying to convince the U.S. that it's okay for them to sell arms to China, the argument is: Russia is selling them the h07 sh17 w34P0N5 tech, so why aren't you blaming them? Then again, two wrongs don't make a right, so I consider the EU selling advanced arms to China as also wrong. \_ The US has been selling weapons to the world's worst people for a generation. It is amazingly hypocritical for us to complain about the EU doing the same thing. \_ Which country is not hypocritical? France and other European countries had been colonizing much of the world. China annexed Tibet and Xinjiang hundreds of years ago. Taiwan (the Nationalists) were oppressing the native Taiwanese decades ago. \_ So the French are simply following in their own best self interest, instead of doing what we want them to do. Is that your complaint? Especially after all the cheese-eating surrender monkey crap, they probably feel like we are not really an ally anymore. What a surprise. \_ The term Taiwanese, used by the pro-independence groups, actually refers to Chinese who settled there before Japan annexed Taiwan, rather than the aborigines, whom the pro-independence groups want to wipe out. But it was a very clever invention perfect for eliciting knee jerk "Taiwan belongs to Taiwanese" slogan. \_ Before the law was passed, Taiwan's defense minister proposed arming missles with chemical weapons and its legistators boasted developing nukes. That stopped after the law is passed. Seems like a good law. \_ increased tensions, yes, but why is the law unnecessary? \_ China doesn't need a law passed by the People's Congress saying they can invade to invade. \_ With a maturing government, China is becoming more reliant on legal codes and protcol than short term political whim. Every country goes through different periods. Dont' forget until < 100 years ago CA was the WWW and "the law" was a joke. \_ This url goes to a pair of enormous floppy breasts. \_ And the above posters are just bots who react to the word China the way I have programmed them. \_ Fixed. |

He seemed pretty nervous, not surprising since he has to explain to all those companies he consulted for why he had so much data *on a laptop* and that it was not encrypted. It's nice to see bad things happen to bad people. \_ The laptop has contacted Microsoft, the black hellicopters will be here any minute! Save yourself while there's still time!!! |

4/21 How do you calculate and determine decibel? Say I have a 20db device. Does that mean it is 20db from X distance? And what is the X constant? In addition, if I have TWO 20db devices running simultaneously, clearly, it doesn't mean 40db. What is it then? Lastly, how much does db decrease relative to distance? Is it linear? quadratic? \_ 0 dB is the threshold of human hearing (humans with good ears). http://en.wikipedia.org/wiki/Decibel You determine dB by buying a meter and viewing the digital readout. Once you have a handle on the wikipedia link, then view: http://www.kodachrome.org/salt/sunderst.htm \_ If you have 2 sources that have 20dB noise individually, then you have 2x, or about +3dB power, giving 23dB. Neglecting the damping effects of air and any echo effects, moving twice as far away from a point sound source gives 4x less power, or -6dB. If you're moving away from a line sound source, such as a long narrow air vent, then if you're 2x as far away you are also exposed to 2x as much sound producer, so it would be -6dB+3dB=-3dB quieter. \_ If you have ten 20dB devices, they become 30dB. If you have one hundred 20dB devices, they become 40dB. A decibel is 10 times log-base-10 of something. (A bel is log-base-10, and a decibel is one-tenth of a bel.) So if you have two 20dB devices, they will be 10 * log((10 ^ (20/10)) * 2) = 23.01dB. Or think of it another way, 20dB + 10 * log(2) = 23.01dB. |
