They have to be replaced peridocially. Just as your lower end tether
will
have to be.

Which is not a really big issue.
The weight of 10Km or so of tether is well within what can be lifted by
one
car.
You just hook on a special car, which climbs to 10Km, cuts the old cable,
ties it on to the new one, and then pays out the new one as the ground
reels it in, before tying on the other end and coming back down.

The atmospheric section, as has been correctly pointed out, is serviceable.
The denial by some that the tether will be subject to damage by lightning
strikes is beyond me to fathom. Chances are it would continue to "pick on"
the same one (unless they are conductive), until it parted, so it should be
unlikely that all of the others would fail in a single storm.

The original claim was not long term damage from accumlated from lighting
strike.

The original claim was that when hit by lighting the entire lenght of ribbon
from the strike point down to the ground would be turned into plasma, this
would then short out the naturaul charges in the upper regions thru the
BeanStalk and basic blow it it up!

Don't believe me, use google to search for BeanStalk and Plasma. The claim
was one lighting strike, or one inducted current flow from the Earth's
magnetic field and the BeanStalk would be converted to plasma.

Do you agree with this claim?

By the way no-one has yet shown *ANY* man-made structure that has been
damaged by a lighting strike conducted thru accumalate dust. Water is
diffirent, I agree that that could happen but I still claim a steam explosion
not plasma.
