Basically, this is a mechanism whereby electromagnetic armature segments of a giant electricmotor slide at very high velocity along inductive magnetic levitation bearing tracks within theelectric motor's stator structure, storing kinetic energy and transferring momentum and electricenergy around the extent of the structure, and also creating a radial outward centrifugal forceagainst the track due to the curved structural track-defined path of the armature segments.

Creating A Basic

Sliding Armature

Energy-Momentum

Transfer Technology

The magnetized

armature segments

inductively transfer

electrical energy and

momentum along

their paths within

maglev tracks, and

provide an outwardforce due to their

deflection from a

straight path by the

curved stator shape,

being an upward

supportive force

relative to the

encircled planet.

The basic shape of

the motor stator is

that of an Orbital

Transfer Trajectory

between the Earthsurface and GEO.

The armature segments are traveling along maglev tracks

on the underside of the motors stator, much faster thanfor an orbital transfer trajectory. The excess velocity

above orbital transfer trajectory velocity presses outward,

upward against the weight of the stator with its live loads.

Primary Structural Support Is By Stored Energy

The actual workdone to payload by

lifting it from ground to GEO is

only16 kWh/kg Based on chemically fueled launch vehicle statistics, it may seem impossibly

expensive to move payload in large quantities from the ground up to GEO.

Yet, consider the calculated actual amount of energy added to a mass simply

by lifting it to GEO altitude and imparting orbital velocity to it there:

= 5.23 x 107 Joules / kg = 14.76 kWh /kg

To add orbital velocity energy at GEO, an additional 0.96 kWh / Kg is needed,3.1 x 103 m/sec, for a total of 15.72 kWh per kg from the equator to GEO. At

$0.10 per kWh electric rates, that is an added energy cost of only $1.58 per kgfrom ground to GEO. Any further expended transportation energy is overheadinefficiency, a function of the type of transportation system.

This compares to the work done to mass by accelerating it to escape velocity,17.8 kWh/kg. Emplacement in GEO is 91% up out of Earths gravity well.

James E. D. Cline Why Do This?

Enormous New Things

Become Possible:

To emplace huge factories

in GEO

To worldwide emplace and

maintain SSPS power

stations in GEO

To emplace total waste

recycling plants into GEOand to transport recycle

materials to/from them.

To emplace GEO spaceport

launch facilities and to lift

spacecraft between ground

and GEO

To emplace first full-sized

space settlements in GEO

and move thousands of

people and their goods up to

live and work there in space

Potentials Made Possible By Utilizing ThisTechnology for Creation Of KESTS To GEO

Early construction of adequate quantities of SolarSatellite Power Stations from earth surface materials

Construction of solar powered total recyclingplants in GEO, and transport of toxic wastes to there for

mass separation processing and then return down to earth Interplanetary exploratory and industrial spacecraftneed only to connect to GEO, already 91% up out of theearths gravity well, also far above the atmosphere

Large scale passively shielded human habitationmaintenance and tourist facilities can be built out of earthsurface materials, easy commute to the ground

For more direct access far from the equator, perhaps KESTS can be built in pairs,

balanced across the equator, leaning on each other where they meet in GEO.

Bending stress needs to be absorbed mostly by stator strength of materials.

Benefits Enormous new business opportunities become available, by

ensuring availability of abundant clean electrical energyworldwide for the future, and by rapidly embracing a space-based civilization:

Ability to emplace many SSPS in the near future

At $0.10/kWh, energy added to place in GEO is only $1.74/kg Ability to profitably take full responsibility for total recycling of

civilizations toxic waste materials of all kinds, and closing theindustrial materials loop

Abundant zero-gee hard vacuum for large mass separator plants

Enable interplanetary industrial spacecraft launches to be from GEOinstead of from the ground

GEO is already 91% up out of the Earths gravitational well

Summary A new field of transportation technology is proposed to be

created

Involves the energy and momentum exchanges betweenelectric motor moving armature segments and the motorsstationary stator maglev track

Armature segments slide along maglev tracks in a hardvacuum at km/s velocities

This technology could be used in:

Electrical energy storage for power grid load leveling

Electrical power transfer across vast distances

Momentum-exchange delivery throughout very long and high

transportation structures Planet-encircling kinetic energy supported ground to space

transportation structures, with wisdom, could open up theEarths ecosystem to the vast resources of the solar system

The enabled business opportunities are diverse and immense.For more info, visit www.kestsgeo.com

ConclusionStarting from advanced electric motor principles, wecould develop a sliding armature energy-momentum

transfer technology as applied to extremely highcapacity transfer of payload between the ground andhigh earth orbit, such as for use in emplacing andmaintaining a ring of immense solar power satellites

around the earth, high capacity toxic refuse totalrecycling plants in high orbit, and a high beachhead91% up out of the earths gravitational well for reachingout to the rest of the solar system. Consider this as an

alternative to near future extreme international conflictsdue to multiple physical resource depletions and toxicmaterials accumulation worldwide.
