Ever wonder why they use Fiberglass Poles in a Tent ?


I didn't know that. I learned something!!!!!

Filerglass Tent Poles are lightweight and breakdown
to a small Packable Size and that is good -but- they
also do not function as a Lightning Attractor like a
Metal Pole would.

The "Plastic" Tent Poles in creap Tents will
often start to wrap in high heat areas.

Know a few people who will only use the "Non
Metalic" Tent Stakes up in the High Sierras as
an extra step to protect themselves from T&L
-but- they leave their metal Pack Frames in
the Tent ? ? ? ;-)

Now we are getting a little ridiculous. if lightening will jump thousands
of feet, what in the world would make you think that a little bit if metal
such as a tent pole would attract it away from where it was headed in the
first place? Youre talking about hundreds of thousands of volts, if not
more. You think that fiberglass wouldnt conduct electricity at that kind of
voltage and current? Please :)

The path that lightning takes is from the bottom up.Or so I once
read.Lightning puts millions of tons of nitrogen into the air.A lot of
the bulk of trees is nitrogen.We are breathing in some nitrogen every
time we take a breath of air.And oxygen and neon and dust and other
thingys too.

Uh, that was supposed to be a joke...a little humor. (I know , very
little) grin. I'm pretty sure most people realize that the Empire
State Building has been hit by lightning and yet is still there.

But, as they say, if ya gotta explain it...

In the meanwhile, try to lighten up a bit--it's better for your health.

I live in one of the worst places in the world for lightning. I have
had battery powered equipment explode, and a SVGA monitor killed during
a storm. It was not only off, the cables were wrapped around the base
because I was rearranging my computer desk when it started. The building
had no windows, yet some of the strikes were so close that the flashes
lit it up like the noonday sun. I also felt the static charge when
several of them hit the marsh behind the radio shack. The thunder was
knocking equipment off the shelves, as well. The news reported over
15,000 strikes during that storm, and I was at the center of it.


But, as they say, if ya gotta explain it...



Then it wasn't funny, or its so old that the Social Security office
has lost its paperwork.

You might think lightning is funny, but around here you hear news
stories of people being hit because they didn't take it seriously.
People run and hide under trees, play golf in the rain, and do other
stupid things, and die from it.

If you want to join them, its your choice, but down make others think
that lightning isn't serious business. T have seen chucks of concrete
blown out of buildings from direct strikes.

One time when I was in Florida, I was gassing up my raggity old van at a
gas station.There was a golf course right across the highway.An elderly
guy in his golf cart drove across the highway to buy a cold soda
pop.There was a golf club in his golf bag that had an electric lamp cord
taped to the handle of that golf club.He said it is his electric golf
club.

The issue is not whether the fiberglass pole would conduct better or
worse than the metal pole, but rather, the issue is where the discharge
originates.

There are multiple phases of a lightening strike. Two significant
phases, the visible ones, are the leader stroke and the return stroke.
The leader stroke is from cloud to sky. It's often not visible, or
obscured by the return blast. The leader stroke will strike an object,
and often, but not always, create an ionized path that will facilitate
the return stroke. It's the return stroke that contains the Wrath of God
energy. And the return stroke originates at the surface and moves from
ground to sky.

The leader stroke, like all electrical phenomena, seek the path of
least resistance to ground. Height and conductivity will matter most,
here. If there is a high object of relative conductivity, the leader
stroke will move there. Living tissue, owing to the solutes within it's
fluids, will have a greater conductivity, and/or break down resistive
materials under heavy voltage more readily than a fiberglass pole. So,
the use of fiberglass is often, but not always, an effective measure of
safety where electrical storms are an issue, because an ionized path can
be created more readily elsewhere with much lower electric field strength.

A metal pole, however, presents a number of electrical advantages to
both the leader stroke and the return blast. Among them, besides the
obvious enhanced conductivity while in contact with the ground, is the
high curvature at the top end of the pole. High curvature on a conductor
concentrates the electric field flux offering a dramatically much easier
release of current than a flat object. This is why users of a Van De
Graaf generator note a corona discharge around the heads of tacks,
points of pins, and the like. A metal pole, stuck in the ground offers
an enormous level of electric activity that should a potential develop,
a discharge would happen at a much lower potential. Making both leader
stroke and a return blast more likely than with a fiberglass pole should
conditions develop.

It also means that many such strokes may be dissipated before they
can become dangerous by releasing electrons through corona discharge at
points of high curvature. This is how lightning rods work. But in the
case of metal tent poles, the ground system is random, not engineered
for efficiency, and poles of even height are often too few in number to
offer sufficient corona release to forestall a stroke.

So, a metal pole becomes more dangerous than a fiberglass pole when
conditions are right for lightning to occur.
