If you go to this URL -
http://liftoff.msfc.nasa.gov/tsslr/
you will find reams of information about the tether experiments that
NASA
is performing.
NASA had little trouble getting the tether to produce electrical
power.
They had plenty of trouble trying to stabilize the instrument sphere at
the
end of the tether. If the sphere was deployed too slow the tether got
tangled. If the sphere was deployed too fast it snapped the tether and
took
off on its own orbit.
