DC power versus AC power

Mon Dec 30 01:45:48 UTC 2002

While I would normally think some of this exaggeration.  When I was 
at Netrail, I did a road trip to upgrade a facility in DC.  It's 
kinda amazing what passed for colo in those days.  The little UPS 
actually had a string of Pet boys car batteries.  Nathan Estes 
dropped a wrench into the battery bay and there was a nice explosion 
according to him.  The wrench literally vaporized.  Now I said that 
wasnt possible.  He will stick to his story to this day.

The only thing I could figure was that it literally moltified into 
super small droplets and just sprayed.  Regardless of whether it's 
completely accurate, he was out searching for another wrench... it 
took a lot of chocolate mile to relax him after that.
