*******************GETTING READY*******************
Enabling Technologies
We already have the pieces to the puzzle ...
We just need to put them together.
6. Time to Upgrade

Transfer Orbits vs. G-force Profiles

Typical transfer takes a semi-orbit (SO); thus, total distance traveled would be one half the distance of the relevant ellipse. At orbital speeds, this takes a while. Most destinations take years.

Line of Sight (LOS) is a straight line from Earth to destination, LOS distance is much less then SO distance. G-force acceleration would enable ships to approximate a straight line path at much greater speeds; this would greatly decrease travel time. Typical destinations would take days.
It's time to upgrade from transfer orbits to g-force profiles.

7a. Close Look at the Particle Stream

As fuel burns, gross weight decreases.
As vessel weight decreases, burn rate also decreases.

To consider ion quantity requirements,

TE constructs following three tables.

Table-1: Every Day Differs. Fuel consumption remains a consistent percentage of current GW; thus, GW is ever decreasing due to fuel burn. TE uses an exponential method {(1-Δt)t}to model daily fuel requirements.

Table-2: Any day: 86,400 Unique Seconds TE arbitrarily chooses Day 20 as an example; Day 20's fuel requirement is 222.91 mTs of water. Simple division approximates an average burn rate of .00258 mT (= 2,580 grams) per second.

Table-3: Pulse requirements During each second, PA will create and expend many plasma packets. Each will contain small quantity of water but a large number of particles. TE arbitrarily assumes a Packet Repetition Frequency (PRF) of 10,000 per second.

Particle Accelerator components:
8. Accelerators - Storage Rings

Storage Rings keep momentum happening.


Component Accelerator Purpose Leverage Space Environ
Plasma SourceProvides charged particles for acceleration.Maybe water will work:
  • Plenty of water in the oceans
  • plenty of comets in space
  • plenty of He3 in the giants
InjectorPuts ions into wave guide. Rate determined by ship's mass.
Wave Guide vacuum tube provides path for particle beam.Design determined by size/shape of ship.
Klystronsgenerate microwaves for the particles to ride.Text coming
Magnetsfocus and steer the particle beam.Required for particle acceleration.
SuperconductorsSave enormous energyRequired for magnet practicality.
Detectorsexamines radiation from particles colliding with each other and with walls of wave guide. Needed for efficiency as well as safety concerns. Not easy to repair wave guide, even harder during powered flight.
Vacuum Systemkeeps wave guide completely clear. Plenty of vacuum in deep space.
Cooling System removes heat generated by equipment.Plenty of cold in space (4° K); can make liquid hydrogen from water supplies.
Storage Ringsstore particle beams temporarily when not in use.Key design factor.
ExtractorPuts ions into exhaust ports.Rate determined by efficiency.
9. Payloads from Earth

Materials from Earth start the process.

One Thousands Lifts per Mission. Terran topsoil, oceanic water and many other Earth bound resources must elevate to orbit to support humanity's space borne mission. If a "lifter" can transport 10 mTs per lift, it will take 300 cycles to export sufficient water for one mission. If there is an equivalent requirement for Terran top soil, then another 300 cycles. Presume another 400+ cycles for other payload requirements then one g-force mission might take 1,000 lifts.

With one strand of ribbon and one lifter; then, elevator capacity is 1 load per one 15 day cycle. At that rate, each g-force mission needs 15,000 days (about 41 years) to completely supply. With multiple strands and multiple lifters, capacity could conceivably increase to 1 load per day. This reduces supply time to 1,000 days or about 3 years.

Conveyor Belt Configuration. TE assumes greatly increased ribbon durability and ribbon redundancy to enable elevator to adopt a conveyor belt configuration. If this enables 1 lifter per hour, then, supply time decreases to about 50 days which would be a reasonable duration to be included into a mission's Work Breakdown Schedule (WBS).

Improvements could further reduce load time.
10. Lunar Launch Platform

Moon makes final contribution.


Filler for TE SpaceshipOne ton of helium-3 requires processing 14,000 tons of lunar regolith. This resource could be used to help build enormous infrastructure of g-force spacecraft.
