<p><b>Initial purpose</b>: to effciently lift enough Solar Power Satellites to GEO to provide
abundant clean electrical power for the world, and to power the
transportation system itself thereafter.</p>
<p><b>Orbital Access Technique: </b>Payload-carrying vehicles are lifted from ground to high earth
orbit, and back, by electrodynamically braking against upward-bound
high velocity mass streams. Those mass streams are track-constrained
to an orbital transfer trajectory path between ground and GEO,
yet the stream's velocity is much higher than orbital transfer
velocity, such that the resultant excess outward centrifugal force
nearly balances the force of gravity on the mass of the associated
track and hard vacuum environment tubing forming the transportation
structure. </p>
<p><b>Longer Term Goals:</b> Abundant clean electric power for the whole world, before petrochemical
are all burned up; solar-powered total recycling of even the worst
of civilization's toxic waste materials; efficiently high spaceports
from which conventional rockets can easily reach out to the rest
of the solar system; and a place to build passively shielded large
scale space habitats such as those designed in the mid-1970's
for use at L-5 but now with easy rail commute to ground... a ring
of such space habitats, built of lunar and asteroidal materials
and infilling GEO, could support 3 times the entire present-day
population of our planet, with a comfortable sustainable lifestyle
for all... potentially.</p>
