F.2.1.1.3 Transport Data

This section includes data on requirements and alternatives which affect the main Provide Transport Capacity function as a whole.

Transport Requirements

As with Habitation, cost data are based on January 2013 as nearly as possible. Numerical values of all types are for the purpose of estimating the design, inputs, and outputs of all the location functions. Actual design will to some degree be a matter of choice for project participants and residents. This is less true for Transport elements than Habitation because transport has to function across the location and also outside it, so cannot be entirely different for each person. Despite that, we will try to preserve flexibility and choice where possible.

The Transport functions are divided by types into external Bulk Cargo, Delicate Cargo, and Human delivery, and Internal transport. We expect many of the hardware elements to carry out these functions will be shared across the functions, so most of the requirements are maintained at this main function level, and detailed values estimated for the component functions.

Transport Alternatives

These alternatives apply to the main Transport function as a whole.

F.2.1.1.3.1 Bulk Cargo Data

We estimate the following amounts for discrete bulk cargo, both to and from the location, and internally within the location. The delivery distances will depend on the land parcel distribution, but are estimated per the calculations under Internal Transport Data below. They will also shift slightly based on growth in the overall location size with population growth, and increasing fraction of production from local resources.

- Earthmoving for Habitation construction at 800 m3/person x short travel distance. Density averages 2 tons/cubic meter.
- Building materials for Habitation construction at 200 tons/person x 30-40 km one-way trip distance.
- Initial materials for Production and Transport at 150 tons/person x 30-40 km one-way trip average.
- Ongoing bulk materials transport at 15 tons/person/year x 3 trips per material x 20 km round trip average. 15 tons comes from 4% of initial materials for maintenance and modification. The reason for three trips is from source to Production area, movement within Production, then delivery to final point of use.

For fluids, US water use is 1500 cubic meters/person/year for all uses, so we adopt that as an estimate for both water supply and waste water transport. Transport distance will depend on whether it is from public or local supply. An undetermined amount of natural or other fuel gases would need to be delivered if they part of the location design, as well as an estimated 2 tons liquid fuel for the vehicles themselves if they are powered that way.

F.2.1.1.3.2 Delicate Cargo Data

Delicate cargo includes items like furniture, electronics, hazardous chemicals, and food, which need some level of protection during delivery. We estimate Transport at:

- Habitation movable contents at 40 tons/person initially, plus 2.5 tons/person/year for new items and moves for residents.
- Chemicals are estimated at 2 tons/person/year (mostly in Production)
- Food is estimated at 500 kg/person/year x 20 km average distance.

In addition to the cargo itself, items in this category need protection from the outside environment, shock and vibration, etc. We will make an estimate of 25% on average for padding, boxes and crates, and refrigeration.

F.2.1.1.3.3 Human Transport Data

We calculated 21,700 km/person/year previously for passenger transport. If we assume 4 person-hours/day usage x 40 km/hr average vehicle velocity, we need 0.375 passenger vehicles/person. This is lower than the US average, but we can design vehicles to self-drive when empty to the next user, optimize routing among residents and project members to increase passengers/trip, or simply reduce travel distance from less need to work outside jobs or make shopping trips as often. The conventional alternative is to use existing vehicles, and merely produce fuel for them. If building vehicles, then production requirements would theoretically be 0.375 x new resident population, and 0.02 units/per/year maintenance and replacement. Since most people already have vehicles, initial production will likely be much less than theoretical.

F.2.1.1.4.4 Internal Transport Data

Internal transport is where both ends of the trip are at the location. The amount required will greatly depend on whether the location land is one parcel or distributed into many parcels. For estimating purposes, we assume the in the distributed case the parcels follow a Zipf (harmonic) distribution with a minimum size of 1 hectare (2.5 acres). We estimate 0.45 hectare per person, so for 75 people we need 33.75 hectare/minimum parcels (83 acres). This yields approximately 11 parcels with the largest at 11 hectares (27 acres). For a population of 660 we need 297 hectares, with approximately 63 parcels, the largest being 63 hectare.

If the parcels are on average distributed with 1/2 within 30 minutes of the center of area of all the parcels, and successive halves for each additional 30 minute travel time, the average and maximum distances are (1.625, 4) and (1.875, 6) times 30 minutes for 75 and 660 population. The average distance between two random points in a circle is 2/3 the diameter, where that is 1 hour for a unit distance. This gives 65 and 75 minute average one-way travel times. Using 40 km/hr average travel speed we get 43 and 50 km average trip distance between parcels. The probability of a trip starting and ending on the same parcel is 33% and 21% respectively, for which the distance is less than 1 km, and we can use zero as an approximation. This lowers the average trip distance including same-parcel trips to 29 and 40 km.

For the non-distributed case, we can assume a land parcel with 2:1 aspect ratio, and therefore 400 x 800 meter and 1200 x 2400 meter dimensions for the 75 and 660 person sizes. If the average trip is 2/3 the long dimension, then we get 0.53 and 1.6 km average trip distances. For a single parcel, 100% of the internal transport is on the same parcel. Usefulness of alternate designs is much higher in this case because we can fully choose the design. In the distributed case we have to work within what is allowed on public routes.

If we have a goal of supplying 85% of resident needs from internal resources, then 85% of transport will be internal trips. The remaining 15% are external trips, where one end is not at location property. We will assume the same distribution of trip distances as among parcels in the distributed case, but this portion remains the same whether the parcels are distributed or not. At the start of construction there will be no residents, so all travel will be distributed. As the location is developed, the mix will shift according to the degree of land concentration.


F.2.1.1.1 Production Data

This section includes data on requirements and alternatives for the main Provide Production Capacity function as a whole.

Production Requirements

Cost data are based on January 2013 as nearly as possible, and dollar amounts in requirements are allocated for the purpose of estimating the design, inputs, and outputs of the various functions. Actual design and dollar amounts for Production will be derived from the complete needs of the location and the optimized set of alternatives chosen. The Production elements are expected to evolve over time. Meeting the following requirements is expected at the end of location growth (660 people), but approaching or reaching them earlier is desired. Maximizing the fraction of requirements met over time is used to select between different growth paths.

The first increment of major Production elements (also known as the Seed Factory) must be inherited from the Technology Development phase or supplied from outside, because they cannot produce themselves from nothing. The first increment also includes necessary attachments, bits, tooling, and conventional small workshop tools. After the first increment, an increasing percentage of Production and expansion is done locally, and a decreasing percentage is supplied from outside to reach the 85% goal. For purposes of design and tracking, additional increments of outside supplied items may be organized into Expansion Sets. The delivery schedule of items will be set by actual Production needs, however they are organized and tracked.
If not enough funding or participants are available to reach a 75 people/year production rate at first, a reduced starting rate of 45/year is an option, adding 5/year to reach the 11% growth rate, and ramping up above 75/year later on to reach the 660 person goal in 9 years. The Production elements will still be designed for a rate of 75 per year at full scale, because we need a definite scale to develop the various pieces around.
Since we are trying to keep the Seed Factory relatively simple and inexpensive, the first elements should be as flexible as possible. Later additions can be dedicated to particular purposes and specialized/optimized for them. An initial candidate list, which is very likely to change, includes:
- (1) Modular robotic tractor with multiple attachments for different land and construction tasks.
- (2) Concentrating solar furnace facility with different focal targets for different heating jobs.
- (3) Bridge mill frame with 4 replaceable head mounts (LF, RF, LR, RR) and pallet changing sliding table for different machining/printing/cutting/painting/other tasks. Sawmill operation uses both LF and RF mounts to hold the bandsaw frame. Heads and table can have additional axes for multi-axis (>3) operation.
- (4) Horizontal lathe with 4 rails: two for main spindle/chuck, tailstock/secondary spindle/supports, and two for cross-slide/turret/mill head, with tool and attachment exchange.
- (5) Modular chemical process plant to produce different bulk materials by connecting various modules in different ways.
- (6) Hydraulic press/rolling mill/ironworker to shape thinner cold metal, thicker hot metal, or press non-metallic materials by various inserted dies, molds, and blades.
- (7) Electrical/Electronic fabrication shop for making motors, generators, circuit boards, and similar items. This element is not one big machine, but a collection of a number of smaller items.
The Production share of the total output is 75% of local output x 85% local share of total output = 63.75% x $156,000/year = $99,450/year/resident. This assumes 50% of full time work by the residents in total, and thus 32% in production tasks. This goal may not be reached the first year because of lower levels of automation or lack of some production machines, but intended to be reached by the end of location construction. Participants who are not residents have the same production output goal, but do not get the benefit of integrated Habitation and Transport use because they are not physically at the location. Instead they get increased capital in the location, or withdraw a larger share of products.
- Increasing general food and housing security by designing climate-proof systems (greenhouses and energy sufficient habitation) and systems to produce them,
- Contributing to an asteroid hazard detection telescope,
- Developing modified trees or advance planting ahead of climate zone shifts, since trees are not mobile and take time to grow. Forests are net Carbon accumulators.
- Developing systems to increase albedo, reduce soot emissions, absorb or reduce carbon emissions to reduce climate effects,
- Developing extraction methods for low-grade ores, thus alleviating resource depletion.
Many of these approaches require development, and are partly assigned back to Phase 0: Technology Development, but a continuing task to implement them is included in this phase.
