Reasons posted were same reasons promoted the ESE protection
industry. That industry says pointed rods that discharge air will then
prevent lightning.

Meanwhile, research demonstrates that blunt rods are better
protectors than pointed ones. But both are irrelevant. That lightning
rod is made effective by its earthing.


Thats incorrect. And blunt rods being better would be some remarkable new
science.

For example, a FL couple suffered direct lightning strikes to an
exterior wall. They installed lightning rods. Lightning instead struck
that exterior wall again. Why? Bathroom plumbing connected to deeper
and more conductive earth. Lightning rods were only connected to 8 foot
rods in sand. Lightning seeks the better earth ground - that plumbing
inside the wall. To make lightning rods effective - too divert
lightning to earth on circuits that are not destructive - those
lightning rods must be connected (earthed) to better conductive soil
beneath the sand.


Ligntning rods do not stop lightning. They are a deterrent only. You
show a lack of understanding of the fundamentals of static electricity.
What you state as fact is only 1/2 true. What you refute is equally 1/2
true.

The lightning rods deterrent behavior does not require it have the best
ground, only a sufficient one. The lightning rods attractant behavior
requires it to have the better ground. Still, with the amount voltage you
will see energy going through both paths to ground.

Just like in protectors - the lightning rod is only as effective as
its earth ground. Earth ground (not the lightning rod and not the
protector) provides protection.

Wrong. Its effectiveness as an attractor is tied to the quality of its
earth ground. Its effectiveness to leak off static electricity is tied to
its shape, and the ground as well. but the ground does not have to be the
best around, just sufficient.


Where he realizes it or not, dnoyeB posted ESE industry reasoning
that was roundly rejected by the National Fire Protection Association -
who write the National Electrical Code. ESE industry claims to stop
lightning by discharging the air.

If you discharge the static electricity, then you can stop lightning. So
the claim that discharging the clouds/ground will stop lightning is 100%
scientific and correct. The flaw is that you can't guarantee that you can
discharge it fully, or continuously or fast enough.

We may share the same resonings because what I state is based on the laws
of physics. So my statements are true. However, I am not reaching the
same conclusion. I doube the reasoning was rejected but more likely they
decided the conclusion did not follow from the reasoning.


What makes a shower safe from lightning? Need lightning pass
through a bathroom to obtain earth ground? If not, then any incoming
lightning path has been properly bonded (connected) to earth ground so
that lightning is diverted (non-destructively) into earth. What makes
that earthed connection better? Shorter wire. No sharp bends. Not
inside metallic conduit. Separated from other non-grounding wires. Etc.

"No sharp bends" you realize why this is right? Same principle as
leaking off the static charge.



Protection has always been about diverting lightning into earth
where energy is harmlessly dissipated. Any protector or lightning rod
that does not dissipate lightning harmlessly in earth is not effective
and violates the science as even demonstrated by Franklin in 1752. Where
is that energy dissipated? That is what provides protection.

I agree. If you are further claiming that the act of leaking off static
charge has been proven ineffective, then I will accept that.
