VOLUME 0: ELEVATIONAL Table of Contents

Long term deployment 
of space borne enterprises

 require reliable elevation 
of Earth bound resources

without risky rockets.


1. ELEVATE PAYLOADS FROM EARTHHumanity's initial space presence will require frequent, reliable elevation of materials from Earth to orbit.  BACKGROUND: Traditional "space elevator" concept could be a start.
2. UP-LINK: Climbers Ascend Tether to GEO Node. Associated "strain" might break even the strongest cable at anytime. Thus, a physical cable requires an instant backup capability.
3. DOWN-LINK: Climbers Descend Tether to Marine Anchor.  During normal ops, dedicated downlink would provide downward bound service for climbers to return to Earth.  However, during emergency ops, downlink tether could alternate service as an upward bound tether; then, service downward bound climbers.
4. OUT-LINK: Beyond GEO to Apex Anchor.  Thought Experiment (TE) considers innovative ways to leverage Space Elevator (SE) beyond Geosynchronous Equatorial Orbit (GEO).  Beyond  GEO, "elevator" transforms to "conveyor belt".  Consider using O'Neill's Habitat in Apex Anchor role.
5. LIFEBOATS: Ride the Virtual Tether.  For a rapid return to Earth's surface, necessity will give birth to lifeboat vehicles which can anytime, safely descend back to terra firma via Earth's gravity to Low Earth Orbit (LEO); then, rapidly decelerate via an Earth based, high speed, particle beam to land at zero velocity at surface.
6. TE BASE STATION CONCEPT:  Forgo Down-Link's physical tether; exclusively use lifeboats to travel Down-Link Virtual Tether back to Base Station. However; Down-Link Base Station will need a particle beam capability.
7. SEVERED TETHER: Several scenarios; some end badly.
8.  ELEVATIONAL ALTERNATIVES  Besides the Space Elevator (SE), there are several other non-rocket proposals which might lift a vehicle and payload from Earth's surface to Earth's orbit.  This chapter briefly describes a few.
9. BEAM ME UP! Thought Experiment (TE) proposes another non-rocket method to reach GEO.  Replace Up-Link's physical tether with a virtual tether, a beam of ions from Base Station. This method can be much more practical than either tether or other elevational alternatives.
10. HIGH STAGE ONE: Leverage Lofstrom's Launch Loop concept to avoid wind and weather in lower atmosphere and get a head start on trip to GEO.
11. CONSTRUCTING SPACE ELEVATOR. Using physical tether to construct subsequent tethers is great idea, but initial tether must use risky rockets to deploy.  However, virtual tether (particle beam) does not need risky rockets during initial deployment nor anytime.
12. SPACE TUG.  TE's Space Tug could best be used in moving Space Habitats between terrestrial orbits or even to interplanetary orbits. 
13. ELEVATIONAL CHALLENGES MAIN CHALLENGE: Quickly move pax/cargo from Earth's Equator to GEO without the absurdly long cable (which might extend 1/4 distance to the Moon!!!!).
14. BASE OFF EQUATOR?  Can a tether anchor off the Equator??  Not much.  HOWEVER, a Base Station can locate well away from equator and still project an ion beam toward the GEO Node. This chapter expands envelope of ionic launch locations from strictly on the Equator to well beyond. 
15. BEAM ME OUT!!! Expand range of orbital destinations from strictly GEO to well beyond. Even escape Earth's gravity to travel throughout the Solar System.
