Ärende: UPS units and Lightning
===============================

  I do have some surge protected power stripes besides the 3 UPS's. I've got
3...one for each of the computers (the main BBS computer, and one for
each of the laptops). The original BBS computer quit booting up (not
sure if it is motherboard or hard drive failure), but I quit using it at
least 2 months ago. I basically need to just take it to PC Assistance,
and have them wipe the drive, and use the rest for parts.

  However, if there's a threat of thunderstorms in my area, EVERYTHING
gets unplugged in the apartment...EXCEPT for the refrigerator/freezer,
stove, dishwasher, and garbage disposal, as they're part of the
apartment, and I wouldn't be responsible for repair or replacement on
those if they got zapped by a lightning strike or surge.

  Thunderstorms in Arkansas are prolific lightning producers...and
sometimes, it's like living in an ungrounded Faraday cage. In one
recent 12 hour period, they measured 2500 lightning strikes across
Arkansas...with Pulaski County (Little Rock) getting 500 strikes in one
hour!!

  I heard of a ham radio operator who had SPARED NO EXPENSE for
lightning protection. You name it, he bought it, and installed it. He
took a direct or very close to direct hit...his tower, mast, antenna,
and coaxial cable...were VAPORIZED (not a trace left)...then all of his
UPS's and the devices they were protecting, were DESTROYED. So, all that
money that he spent was for nothing.

  Take it from someone who has personally suffered 2 indirect
strikes...I still got the shock, but carry no electrical charge, and can
be handled safely <G>...about the power of lightning. Each bolt:

1) Is 5 miles long
2) Can strike as much as 20 miles from the parent thunderstorm
3) Is 50,000 Degrees Fahrenheit (5 times hotter than the sun's surface)
4) Has 300,000 volts...and 30,000 amps of electricity

  In short, it's no contest. I'd rather be offline a few hours or days,
rather than permanently, from a lightning strike.

  I've always used UPS's from American Power Conversion, even when the
BBS first came online in December, 1990 (on a Radio Shack 32K Model 100
laptop). In fact, over 20 years ago, my submission on how good APC units
work, was noted as "Letter Of The Month". The image from that is on the
BBS's website (toward the bottom of the page) at
