and
evaporation math

and seeing that today is a nice hot sunny day...
and that i have to hose out my recycling trashcans...
i broke the hose out and thought some more

the first thing i thought of was a cold beer

that taken care of, i set it down and crawled behind the groaning 
aircon compressor in back

i see a 15 amp 220V circuit, actual running rating is 12 A (with various
fusing options for startup current...and does not include fan motor 
indoors... so i will use the 15 A number...)

that works out to is 3.3KW unit .. eats 3.3KWh per hour

1 cubic foot of water saves 1.78 KWh 

so evry cubic foot evaporated shuts my aircon off for 32 minnits

so i crawled out, took a deep swig, smiled broadly  
and set the hose on 'kill'

of course... this is an experiment... so i need to keep trak of indoor 
and outdoor temperature and humidity, and water usage and a buncha udder 
stuff like aircon running time ... and utility bills ...

in my copious spare time ... watch this space for further details
