Carousel Spacecraft Electrical LiftAround the Earth Up To GEO
James E. D. Cline
Exploring both the technological feasibility,
and the potential impact on civilization, of a
non-tether, kinetic energy supported, electrical
lift rail system operating between ground and
GEO

The intent here is to provide a conceptual
outline for an alternate, very positive, near
future pathway into space for civilization
Provide transportation technological basis
Use the electrodynamic interactions insynchronous electric motor technology
Would allow construction of Satellite
Solar Power Stations finally in GEO Allow mass-spectrometer type total
recycling in GEO; Spaceports in GEO

Conceptual complexity vs.
physical size
The common CD/DVD drive in todays
computers and music systems has a similarbasic conceptual complexity
Both utilize data-controlled synchronous
rotary and linear electric motor principles But the Space Carousel would have much
greater 131,300 Km perimeter

Similarly, mass sliding in a curved track entirely
around the earth produces an outward force opposite
to the force of gravity, supporting tracks weight

The velocity of the sliding mass is chosen to be
slightly greater than that needed to just offset the
weight of the track, its tubing and loads

Also, the outer-track spacecraft are being lifted up
along the structure by loosely dragging against the
upward-moving mass sliding on the inner track.

So the structural weight support is primarily a rotary
electrical motor function, and the lift of captive
spacecraft is a servoed linear motor function

Electrical power is input to the synchronous mass
drivers at the earth terminal site, there converted into
kinetic energy of the sliding armature mass streams.

That kinetic energy is thus distributed throughout the
structure, and in turn can be electromagnetically
tapped into anywhere, for lifting or servopositioning.

The sliding armature mass streams are in contra-
rotating paired sets to balance gyroscopic
precession, and flow in a cycloid path as the earth
rotates.

Within the atmosphere, the tubing protects the
meteoric velocity armature mass streams from

A proposed new
transportation system needs
to provide initial vision as
to what possibilities it
would allow. Since the
electrical equivalent of the
energy that is given to a
mass by moving it from theequatorial surface up to
GEO is only 15.7 KWh/Kg,
an electrically powered
transportation system
functioning with an order of
magnitude of that value,
seems likely to allow
applications such as:

ConclusionGiven wholesome adequate
means for human coping withstress of change during thedevelopment, construction andapplication of a carousel spaceelevator project with its enabledapplications, this system surelycould provide wholesome newdirection to the vigorous drama of people in the flowof civilization to increase the survivability of all, in the
race for completion and application before exhaustionof low cost, high energy supplies.
