>i have a moral problem with using too much energy...
me too. our uu church is having a candlelight vigil tonight for the 1000
americans (and 1 million iraquis?) killed in our latest gulf war. skipping
the candles and standing outdoors under our 1000 watts of dusk-to-dawn
parking lot lights might be more to the point. we might even (gasp!) turn
them off tonight. our us energy appetite is a large part of the problem.
how did our oil get under their country? :-)

steve baer went all the way from albuquerque to west texas to find
a new pickup truck with no ac. he and his wife holly use 80 kwh/mo
of electricity, less than 1/10 of an average us household.

and people feel cooler. equally comfy at 80 f with no air movement and
82.6 f with 0.5 m/s, at 60% rh, according to the ashrae 55-2004 standard,
based on worldwide surveys of over 21,000 people.

you might replace it with grainger's $73 4tm66 16" reversible window fan,
which moves 3290 cfm with 84.1 watts or their $183 3c614 20" window fan,
which moves 7005 cfm with 170 watts, which can capture lots of cool night
air. typical whole house fans are harder to mount, leak wintertime air,
cost twice as much, and are half as efficient.

moreso than phila, at 77.0 vs 76.7 f in july,
with average daily mins of 67.2 and 66.8...
