i've been enjoying the heat so far this summer, working outside
more than usual. just emptied a 6'x8'x20' dumpster full of horse 
manure and bedding into a 2' deep mulch garden--160 trips with a
6 ft^3 wheelbarrow. the 100 tomato plants look stressed, but the
basil's ok, and it grows a large 4" crop of mushrooms every night,
which disappear the next day. skinny, blackish-gray and poisonous-
looking, with occasional headless white stalks. anyone have a copy
of that french mushroom cyclopedia with nice color pictures and
ratings in multiple forks and hospital beds? some have lots of
each, with six month delays, for adventurous terminal gourmands.

with a wide hat and lots of water, choosing to work outside on a 90 f
sunny day seems less oppressive than quietly sweating in a warm office.

be more creative? i used to work with an electronic technician 
who lived in a cardboard box in a parking lot. hated the job.
he later became a clown, for ringling brothers, as i recall.

sounds fetching, caryn, with a desirably large surface to volume ratio.
i'm typing naked at the keyboard.

of course. special traffic lanes.

eat the ice: 144 btu/lb to melt it plus 67 to raise it from 32 to 98.6
makes 211 btu, or about 53 calories, eg no-cal water ice with about
3 teaspoons of real sugar per pint, or sure-fire weight loss
with no sugar, at about 8 gallons per pound...

this works a lot better in vacuo, with fewer air molecules competing
with water molecules at the dessicant surface. get a limo or hearse
or ambulance with one of those glass partitions, and evacuate the back
seats, with a large lithium chloride fountain and pond? some german
rail cars have something like this on top.

licl works better. it can absorb 11x its weight in water, (about
11k btu/lb), and the entrained dust might prevent road rage.
there's enough waste heat in a car to make a closed cycle and
reconcentrate (evaporate) the diluted solution.

then again, wooden balls behind one's back seem to help a lot.
copper would be even cooler, or magnets, to cure cancer, etc.
