8/18    Forget about Prius.  Does the VW TDI diesel engine Jetta and
        Passat help save fuel costs?  are there drawbacks?  diesel
        seems to be about the same price as the lowest grade gasoline,
        but does it really run 30% further per gallon?
        \_ you can convert diesel engines to run on vegetable oil.  You
           need to start and end the day on diesel to clean out the engine,
           but once it heats up you switch over to a second gas tank, which
           you could possibly fill for free if you know anyone in the
           restaurant business.  ...I have no idea what level of emissions
           this produces, though.  -sax
        \_ yes, and you get almost no power as a bargin!
           \_ The Prius seems to have even less.  76 vs. 100 BHP.
           \_ HP ratings don't tell the whole story. You get lots
              of torque at low RPM.
              \_ Yup.  Typical for diesel engines.
        \_ Where are you located? Everywhere I've looked Diesel is more
           expensive than Premium these days.
           \_ chicago.  maybe california has more environment tax?
              \_ Yep.  Diesel #2 (auto diesel) is more than premium unleaded
                 in CA and has been for about a year or two.
              \_ Close.  It is more tax, but road tax, not environment tax.
        \_ Diesel has more energy per gram. I don't think it is 30% but
           it is quite a bit. Also, the combustion process for diesel is
           more efficient, extracting more of the energy and wasting less
           as exhaust and heat. -ausman

2/3     Can someone explain to me why no car mfgrs. produce a sports car
        with a turbodiesel?  I rode in a friend's A6 TDI, not a small auto,
        which went like shit off a shovel.  Just curious.  -John
        \_ Probably because not a lot of people like diesel, it's not even
           economical anymore. Plus a sports coup with a turbo diesel would
           probably not meet emmission standards, after all, diesel is

7/20    Do people not know that the only place where there is no speed
        limit is on a freeway onramp?  Which means that it is the entrant
        driver's job to speed up and get in past the existing traffic?
        \_ The ones who can't accelerate are in SUVs
           \_ True.  My 2nd-gen Prius (not the 2010) accelerates on the
              on-ramps fine.  -- !OP

5/31    I was talking to a harpist who asked me if there were any pieces
        that she shouldn't play at my wedding. I said... no, why would
        there be restriction? She told me there may be religious reasons
        or pieces that may touch some nerves. For example, she played
        for Jewish weddings and a few times she's been asked to not play
        Wagner's Wedding march. I find it interesting that 50 years after

        racks?  Let's assume it has side panels as well as front and rear
        doors.
        \_ I haven't done that but I've done sound proof of my Prius and
           it works quite well. The secret was putting in thick sound
           material. Look at the following crappy example:
