But of couse, most who discuss this topic don't know the differences
between economy and efficiency; to wit this thread... so you're
admitting you can't use a dictionary, words for you mean whatever you
want them to mean.


For example the boiler in my house wears a big label
that it is 90% efficient.

So what, only the boiler is efficient... its ability to heat a house
is only as efficient as the house being heated is efficient.. that's
the entire point... you can run that boiler out in the street and it
will burn fuel at 90pct effiency (that is "X" BTUs per gallon), but
that's only theoretical useable energy, it in no way transfers to
90pct efficiency at house heating, because every house situation is
different (you may heat your house with the windows open, like tenants
who don't pay for heat), just like everyone who drives a vehicle
drives differently... just like people who lease vehicles don't
maintain them... the subsequent repairs are figured into those lease
payments, there's no economy to leasing, it's just something the lazy
no account bastards do because that's how they live in all aspects of
their puny little lives, and so the car dealerships being much smarter
afford the pinheads a service for which they glady reap the monetary
benefits. I mean what kind of imbecile thinks a dealership is leasing
cars as a humanitarian endeaver... and they ain't preying on the
imbeciles, they're imbeciles after all, regardless.

That MPG rating for vehicles only applies to constant ideal
conditions; total vehicle is in top mechanical condition, tires
properly inflated, not overloaded, is driven on level ground, does not
exceed 55 mph, not driven into a head wind, and many other factors,
such as with all windows closed and A/C off. Those MPG ratings are
merely a relative economy guide and hasn't a whit to do with
efficiency. Efficiency of a motor can only be assertained by bench
testing under laboratory conditions... that engine may be very
efficient in the lab but put it in a vehicle with a driver and *all*
efficiency is out the window, then it's *all* about how one drives...
leaving that engine idling for two hours, how efficient is that. MPG
ratings are all about economy, has nothing to do with inherent
efficiency (efficiency is a static number, is constant whether the
vehicle is driven or parked). It's very rare for a vehicle to achieve
its MPG rating in actual use... maybe if only driven downhill with a
tail wind. And not only does that MPG rating come with a disclaimer*,
there are also *2* MPG ratings, yet another economy escape route...
when it says City driving it doesn't say _which_ city... just try
driving in NYC, you can burn up an entire Tank of gas to drive 20
miles (I wasn't kidding when I said 2 hours idling, in NYC you'll idle
more than you move)... for NYC driving it would be more honest to give
a TPM rating. That's why the vast majority of NYC residents don't own
a vehicle, the vehicle may be very efficient but it's not economical
to drive there... in fact it costs more to park than to drive... and
people do, they drive round and round for hours waiting for someone to
pull out of a parking spot. And then they have to worry they don't
get stabbed/shot by the other vultures looking for a spot.
Efficiency... not on your life.
