Alternative space elevator

Some apparently brilliant people think we can't build the space
elevator as Dr. Edwards envisions, so let's analyze some
alternatives. Space rated tether may fall short of projections
for CNT = carbon nano tube. Segments 3700 kilometers =
2200 miles long, 20 micrometers thick, 100,000 micrometers
wide = two million square micrometers = 2 square millimeters
= 0.02 square centimeters = 0.02 grams per cm length = two
grams per meter of tether = 7,400,000 grams of CNT =
7.4 metric tones of CNT if the average density is one
(same as water). This permits starting construction as soon
as 1% of the required CNT = carbon nano tube is available,
even if the CNT is slightly substandard. This can be launched
from the space shuttle or several other existing launch systems.
coriolis effect will make it more horizontal than vertical, but
an ion engine pulling one end to an altitude of 4000 kilometers
will make it approximately vertical in a few weeks. Gravity and
centripetal force help, but they are slow. A half ton climber
can start moving on the tether as soon as the first kilometer
has been unwound off the reel. The climber can get its power
from surface of Earth lasers just as Dr. Edwards plans, except
the solar panel is a moving target. If problems occur at 4000
kilometers, we may have to rethink laser propulsion. Control
of the climber should be temporarily from the space shuttle
as it may be some help in unwinding the tether. The climber
can start adding a thread before the tether reaches vertical.
At 37 kilometers per hour, average, it will take 100 hours to
add one re-enforcing thread. Hopefully improved models can
lay thread faster. After the thread is in place the reel will be
released making the climber lighter and faster. Fast start
and direction reversals will be tested making transients of
various kinds on the tether. A stretch transient will reflect
back and forth between the ion engine and the climber with
a period of one day, if the transient moves at an average
speed of 308 kilometers per hour. Maximum resonance will
be attempted to learn how to make, utilize and surpress
transients. This tether should attempt to snatch a payload
from Earth's upper atmosphere with a compression transient
as this may be a partial alternative to a laser powered elevator.
A lot of energy is stored in a transient on a 100,000 kilometer
tether. The climber needs to be tested at full power, in
vacuum, in sunlight AND bathed in the energy from the Earth
laser to be sure it will not overheat. Likely a large radiator
will be necessary to dispose of waste heat.
Assuming the first segment looks good, ten are needed to
geo altitude, 27 to the far end = 100,000 kilometers altitude.
The tether slows as each segment is added, until the tether
is stationary (except for transients) with respect to the
equator of Earth, before the last segment is added. This
shorter segment is designed to be reliable in Earth's
atmosphere. The weight of last shorter segment pulls the
entire tether downward slowly to the anchoring point on an
at sea platform. Ballast is enroute to the far end to stop the
tether from falling toward Earth. A properly timed
compression transient (10 day period?) can help restore
tension after the tether is attached to the at sea platform.
I'm sure I have some errors, so please correct, embellish
and/or comment. Neil
