"and [spline balls] work".... "work" being a relative term, I'd think. Can't
be absolute (as in... there's never been a strike with a spline ball
installed) or there would be no issue to discuss. Can't be absolute the
other way (as in... spline balls always get struck by any lighning in a ten
mile radius) or... again... there would be no discussion needed. Sometimes
spline balls appear to work, and sometimes they don't... might be a more
reasonable statement.
But people sure do insist on absolutes, don't they? If it exists, it's just
got to be measureable, definable, predictable. To admit that in many
instances it can't be... well, that's just non-scientific thinking. To say
that spline balls (or other pointy things) LESSEN (but do not eliminate) the
chances of a strike.. well, that's just too indefinite. And before we could
consider that possibility, we would absolutely have to completely understand
all the forces involved, such that we could explain exactly how it works and
when it will work and when it won't work. If we can't do all that, we just
can't accept it at all... and it gets relegated to the trash heap.
Sorry... I don't buy it. Man still has limits to his ability to measure,
analyze, and/or understand certain natural phenomena. There are still some
things... like lightning.... that remain in substantial part within the
realm of the unknown, the unpredictable, the anecdotal. Science can be
applied, but only to an extent. Try and apply a "rule" to lightning, and
someone will point out an exception. Try and explain the exception with
another "rule" and there will be another exception. Lokk at the long,
drawn-out discussion here and nothing is resolved. It will come up again in
another 6 months, too, wait and see. There's always a great supply of guys
who have doctorates in lightning behavior, but none of them know whether
lightning will or won't strike YOUR tower next time a T-storm rolls through.
Haven't we figured out by now that all anyone knows is ways to LESSEN the
chances of a strike, and to attempt to render strike energy LESS harmful or
damaging when one occurs. It's part science, but it's also part guesswork
and anecdote.
If some people find spline balls... or live porcupines...or fake golfers...
mounted on their towers makes 'em feel safer, where's the harm? Where's the
proof they WON'T work? Probably on the shelf right next to the proof they
WILL work. Enough already.
Although.... that golfer thing does have its appeal... and chance we could
use a live one? 73, Jerry K3BZ
