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. |
Storage Rings keep momentum happening.

Materials from Earth start the process. 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. |
Moon makes final contribution.
