    Because the airlines get substantial government support (airports, airways, etc) in addition to being classified a common carrier. If the airlines want to discriminate, then they canbloody well pay back ALL of the subsidies that they been given.

    I have a couple of sons with severe allergies and comments like yours tend to make my blood boil.

    Y2K should have been rearing its ugly head in 1970 for financial applications, specifically for 30 year mortgages. California's DMV use of two digit date codes led to an amusing story of a 103 year-old women being denied a drivers license because she was too young.

  6. Badge-engineering? on A Requiem For Saab · · Score: 1
    I would hardly call the 9000 "Badge-engineered", while the design may have borrowed from Fiat, the engines were built in the Scania plant in Sodertalje the bodies were built and cars assembled in Trollhatten. I got a tour of the Trollhatten factory with my former brother-in-law in 1986, and saw both the fabrication of the body panels and assembly of the cars.

    The 9000 was quite a nice design, roomy inside and not overly large outside. The 16 valve turbocharged 4 cylinder engine had some neat features - the central spark-plug allowed for a higher compression ratio and APC allowed operation on varying grades of gasolene.

    And by the way, the Ford V-4's were used in the Sonetts, AFAIK, SAAB never had a car called the Sonata.

  9. Re:The answer is yes. on The Limits To Skepticism · · Score: 1

    Einstein's theories of relativity give easily testable predictions, many of which have measured to great precision. AGW models rely on a water vapor feedback mechanism with an uncertainty close to the same magnitude as the predicted effect. This is more like the factor of ignorance used in civil engineering analysis rather than relativistic physics.

  10. Re:Requires a PHD .... HAHAHAH on The Limits To Skepticism · · Score: 1
    What you're saying is that there is a correlation between CO2/Methane levels and temperature. Question is: did the temperature rise in the past because of rising CO2/methane or did the CO2/methane rise because of rising temperatures.

    Yeah, I know that increasing levels of CO2 and methane will increase the sky temperature (all else being equal). My contention is that climate change (precipitation as well as temperature) is affected by far more than CO2/methane (think other GHG's, particulates, land use, etc.).

  11. Re:Chernobyl again? on NRC Relicensing Old "Zombie" Nuclear Plants · · Score: 1

    The cause of the Chernobyl disaster, however, was the poor design of Russian nuclear power plants.

    The most basic designs problem with the RBMK reactors were that the reactors could remain critical with a complete loss of coolant and that under some operating conditions they had a positive void coefficient of reactivity. In addition, the initial insertion of the scram rods increased reactivity. These all contributed to the prompt critical excursion that led to the destruction of the reactor and release of large amounts of fission products.

    Inherent to the design of light water reactors is that they will shut down with a loss of coolant (coolant and moderator being the same thing), with the worst consequenc being a meltdown.

  12. Re:Thanks for the redundant unit conversion! on UAVs Go Green With Fuel-Cell Powered "Ion Tiger" · · Score: 1
    A perhaps more useful definition of horsepower is 376 mile-pounds per hour, i.e. 1 pound of thrust at 375 MPH equals one horsepower.

    While SI is is a bit more consistent that Imperial/US customary units (would be nice if the unit of length was the light-nanosecond), there are cases where calculations are easier to do in "English" units than SI. An example is calculating the power in HP required for an airplane in level flight which is simply the product of weight in pounds times speed in MPH divided by the product of propeller efficiency and 375. To do the same calculations in SI would require taking into account the gravitational constant (~9.8m/s/s) and converting from km/hr to m/s.

    There are, of course, many situations (probably the majority) where SI is much more convenient than "English" units. I do cringe, however, when someone uses kg as a unit of weight...

    Good point, I'd also wonder how much work would be needed to take care of abnormal events with an electric vehicle, e.g. a collision disturbing the integrity of the battery and wiring. This wuld be less of a problem with compressed air.

    These were also the same environments that fireless steam locomotives were used in. The hot water stores a lot more energy for a given volume than compressed air.

  16. Re:This was first observed in 1971 on Antimatter In Lightning · · Score: 2, Interesting

    And, considering that lightning / thunderstorm related gamma rays are routinely observed with energies up to 10 MeV, there is plenty of energy to create positrons, and so I wouldn't be surprised if all of these reports included the positron annihilation line (or, at least the ones with sensitivity in that energy range).

    Considering that pair production starts becoming significant at gamma energies above 5 MeV (threshold 1.022 MeV), I would be very surprised if there weren't some 0.511 MeV gammas from thunderstorms. It is also likely that the positrons could be formed by interaction between high energy electrons and matter.

    I would think that the gammas are produced in conjunction with sprites (cloud to ionosphere) rather than normal cloud to ground strokes.

    SPARC International, IMHO, actually has a better trademark infringement case than Intel did when Intel went after an organization called "Serenity Inside".

  19. Re:the Washington Meridian on 125 Years of Longitude 0 0' 00" At Greenwich · · Score: 1

    Similarly, at one point they were considering having a brand new unit of length, defined as the length of a pendulum that swung in exactly one second when dangled at sea level at latitude 45 degrees (which would have been similar to, but not quite the same as, the metre).

    Actually that was Jefferson's idea, which he came up with before the French decided on the meter being 1/10,000,000 the distance from the pole to the equator at the Paris Meridian. The beauty of Jefferson's unit of length was that it could be recreated in any well equipped instrument shop (laboratory), something that did not happen with the metric system until 1960.

    As long as I'm ranting about units of length, it would have been really nice if the foot was 98.4% as long as the American customary foot - i.e. one light-nanosecond.

    One thing that keeps the US on the "imperial" system of units is that the land titles are almost always described in feet - changing that would be an enormous undertaking.

    Celsius makes a lot more sense to me, 0 C = water freezes, 100 C = water boils (and it's "compatible" with the Kelvin scale). What was it fahrenheit was measured by? 32 F = water freezes, 100 F = body temperature, 212 F = water boils?

    The boiling point of water is a really lousy datum for a temperature scale. Two problems, first it isn't well defined given a specified pressure, secondly atmospheric pressure depends on both altitude and weather condition.

    FWIW, Fahrenheit is compatible with the Rankine scale. For any kind of calculation regarding temperature, one will need to use a look-up table anyway, so Kelvin doesn't have that much of an advantage over Rankine. If you want a rational temperature scale, use electron-volts.

    I remember seeing an article on a flywheel powered bus in the likes of Popular Science back in the mid-60's. There would be a recharging station every few stops where the flywheel would be spun up again. These stations consisted of something similar to a trolley wire bracket with three contacts (three phase AC) and three wires from the bus would rise up to meet the contacts similar to how a trolley pole contacts the trolley wire.

    Ultracaps and modern power electronics make this idea a lot more practical.
