Last night I was discussing power consumption
with my brother (an electronics. tech) (we were
trying to convince management that flat-panels
were worth the extra cost in power savings.)
and learned some interesting things.
200W = c. $30 /mo? Hrrm... What's your
cost for power there? Here it's about
$.06 / kw/h and in Philly it's about $.08.
24x7x30 = 720 hours per month
200w = .2 kw
cost = kw x time x rate
.2 x 720 x .08 = $11.52/mo
Anyway! :-) Thought it was a wierd coincidence
that you mentioned power stuff the day after
I learn about it.
As I grow older, I pay less attention to what men say. I just
watch what they do.
