REMAKING SETTLLEMENTS. Tool Inventory:

Dollar and energy costs.

4.11.2016

These are very approximate first estimates, to be improved in later revisions of the Remaking study.  The assumption is that the workshop and garden inventories would provide for four households or 15 adult people. The estimates are based on the items used on my homestead. Spare plumbing fittings and purchases of these for household maintenance is not included, due to difficulty of estimation, but a stock of garden irrigation equipment is included. Household plumping woud be best included under house construction, and little equipment would then be needed for maintenance. The embodied energy cost of steel is assumed at 44 MJ/Kg, to include upstream inputs. Note that annual costs are arrived at by dividing total costs by estimated equipment lifetime.

Totals arrived at:

Annual per capita dollar expenditure for the stock of tools and equipment ... $38.

Annual per capita embodiedenergy cost for the stock of tools and equipment ... 84 MJ, i.e., c.23kWh.

Although a full acounting would arrive at somewhat higher totals, the figures are reremarkably low.

Blacksmithing equipment. Few items apart from hammers.

Except for a small anvil. Blower could be leather

            Cylinders (rented from supplier)                                180/y  80(?)                      

Running costs for gas and cylinder rental have not

been included.  Use would be quite low, but these

costs are high relative to other outlays here, maybe

$400/y. However it should be possible to produce

the gases cheaply via local small industry, e.g.,

processing carbide and via electrolysis of water

in the production of hydrogen.                                          200      50

            GARDEN TOOLS.

The assumption is that the equipment used at Pigface Point could be sufficient for 3+ households, or 10 people,

(but the set of pumps could provide for 20.)     Lifetimes would vary, but an overall 10 years is assumed.

(Most wooden handles can be home made.)

Poly pipe. Difficult to estimate, but considerable length needed. Mostly/all small diameter, 12, 19, or 25 mm. A very uncertain estimate is equivalent of 300 m x 19m, = $200. Joiners, Ts, sprinklers etc. home-made brazed from copper tube; assume $100(??) and 5 kg (?)

            How to account community garden tools?

This seems too complex to estimate at this stage. Little equipment would seem to be needed to

establish or maintain woodlots, ponds, orchards. Animal pens and shelter and storage sheds

would be somewhat more costly. Aquaponic equipment would be costly, but long lived assuming

concrete structures.

 

GRAND TOTAL,

... for homestead workshop, community workshop, and homestead garden tools/equipment.

 $38/pp/y       

84MJ/pp/y

Running/operating costs?           

In an established settlement these should be quite low, involving mostly maintenance, including for

instancepaint, nails, screws, bolts, grease, glue, files, hacksaw blades, solder, wire Power would

come mostly from solar panels operating machinery and pumps on sunny days.          

No fertilizers, tractor, pesticides.
