[Publib] Re: Powering off computer gear at night

[Sue Compton]

The hotel I stayed in during ALA in New Orleans had a motion detector
for the air conditioning.  Great for when you left during the day -
didn't work quite so well at night while sleeping.  I had to get up
periodically and dance a jig to get the AC to come on!!  Sue

Sounds like a good test for Consumer Union.

I know someone who worked in an energy efficient place. The lights were
all 
based on motion, no motion they would turn off. Except they would turn
off 
while he was in the office allegedly working. We used to tease  him
about 
sleeping on the job.
