It would be foolish to assume a charge
dissipating system would work 100% of the time.
Not even part of the time.. Thoroughly debunked through analysis,
modeling, and test.
Abdul M. Mousa, “The Applicability of Lightning Elimination Devices to
Substations and Power Lines,” IEEE Transactions on Power Delivery,
Vol. 13, No. 4, Oct. 1998m pp. 1120-1127.
Paper was peer-reviewed by six reviewers under threat of lawsuits.
Paper states that these devices do not work as the manufacturers claim.
google for "mousa lightning elimination" (there's lots of copies out
there)

Grounding runs for
lightning rods are of considerable size and are careful to bend gently
to avoid lumps of inductance.
Gentle bends (or even sharp ones) do not change the inductance, as
long as it's not a complete turn. What bends do is create corners
with small radius of curvature, which in turn leads to increase chance
of an arc jumping from conductor to something else.
Otherwise they would be destroyed the
first time they failed to defuse a strike. Ask yourself what the sharp
thingies are on those commercial towers for. Do you suppose they might
reduce the number and severity of strikes or are they just pretty
decorations for birds and tower climbers to appreciate?
People buy stuff that doesn't work for all kinds of reasons.
Maybe the owner's nephew works for lightningeliminators.com.
Maybe the owner was misled by the snake oil vendor: "Our lightning
eliminator was installed by NASA..." leaving out the "...for an
objective test and it failed miserably"
