Mr Musk.
If the towers can be built to fasten and hold
the weight of lines between the towers,
And be able to have a structure on there,
that can withstand specific type of vehicle
(like the one I designed)
then the turbines lifting the lines,
will be additional safety, instead relying on
them for lifting....
But. Yes. 100KM or even 50KM length wires
are unlikely to withstand,
UNLESS the entire tower from bottom to up,
is designed to distribute the weight of the lines
from within. (Maybe).
Then lithium mining will need to be a extended
branch from that main application.....
