On Sat, 08 Aug 2009 22:07:28 -0500, the infamous "Martin H. Eastburn"
scrawled the following:

If you consider what a bad bearing could do - freeze a shaft and blow up
the motor physically. Flywheel jerking around as a bearing grips and lets
go... Flywheel explodes.

I used to work for Palomar Technology in Carlsbad, CA back when they
were being purchased by SKF. We built vibration monitoring and
inspecting equipment to detect bearing failure prior to it happening.
Another good flak-causing explosion would be a 30' turbine blade at
the local electric generation plant. We wondered if pieces would hit
in Vista if it blew at the SDG&E's Encina Power Plant in Carlsbad.
But PT Vibralogs were showing the bearings to be sound, so we slept at
night. g

Once SKF took over, the corporate feel crept in, Dilbert reared his
ugly head, and they moved the shop to Sandy Eggo (well, Clairmont
Mesa/Little Vietnam.) I bailed with an early retirement package and
started DIVERSIFY! rather than start commuting 3 hours a day for a
$10/hr job. Feh!
