[AT] OT: Gas story

Mon Jul 2 22:01:10 PDT 2007

...so the only fuel that is expanded is the amount that has already come 
out of the
underground line from the tank, ie, the fairly small quantity that is up in 
the pump piping,
plus the slight expansion the gas might have as it travels from underground 
thru the pump..
Probably only the first gallon or less would be mismeasured.

Many big modern stations have a central pump that pressurizes the system,
and the "gas pumps" don't do any real pumping, they just measure.
Could be that if the pump is aboveground, the gas might get heated up a bit 
there.

The initial comment on Flying J is that the problem is (may be)  because 
they bring
in fuel in tankers all day, and the fuel in the underground tanks doesn't 
have time to
cool down + de-expand.

Ideally, gas should be sold by weight, not volume, you just care how many
molecules of gasoline you're getting. Converting pumps will cost money that
will need to be passed on to the consumer, and small stations may go out of 
business.

You need to consider the source of all this nonsense, Dennis Kucinich.
He is the guy who was Cleveland's mayor, who worked hard to drive heavy 
industry
out of town, since he claimed to be helping the working class, who then found
themselves without jobs with the heavy industry that had bailed out.
An absolute opportunist, looking for any way to jump out in front of a cause.
Oddly though, he has a really great looking wife, makes you wonder.

One other thing to note is that gasohol has quite a bit less energy per 
gallon than
straight gasoline, thus will get fewer MPG.
