Space, the final frontier... BP = d / (1 + ( √ (m²1 / m²2))

“… a new geography is being created within which physical distance is less important than electronic connectedness. ” (Seeking source 081117)

Recapping, in paraphrase, STEMI Compression:

STEMI compression in design evolution, as applied to Resilient Communities –
– Space: less volume/area used; “localization… reduction of space needed to support human activity”;
– Time: faster; Just-In-Time production;
– Energy: less energy, higher efficiency; Just-In-Place production reduces transport;
– Mass: less waste; made to order versus mass production;
– Information: “higher efficiency, less management overhead… radical simplification”;

Hypothesis set A:

  1. Limiting Assets – Natural, National, Network Development (Locational ANd Demographic) or L.A.N.D.^2 values, exist;
  2. these values are the result of positive externalities which are due to:
    • intentional investments of site-specific material and social infrastructure;
    • natural opportunities and exogenous natural capital;
    • exposure to social opportunities and demographic energy, access to market, social capital;
  3. These contain both rival and non-rival public goods;
  4. Overuse of non-rival goods can result in them becoming rival;
  5. The rationalisation of provision, or rationing of rival goods, is necessary;
  6. State-allocation is hampered by the problem of cost calculation absent market signals;
  7. Allocation through state-led privatisation of rival goods leads to negative externalities – socialisation of cost, privatisation of profit;

Hypotheses set B:

  1. Technology and design – investment of knowledge – reduce effective spatial and time distance;
  2. Technology and design reduce effective material and energy use;
  3. Both the reductions of effective space-time and matter-energy can be thought of as as reductions of resistance to human action and desire;
  4. The control of such technology and design is equivalent to control of other aspects of LAND2 (hence Infrastructure and Network);
  5. Bottlenecks in such control – whether intentional or not – create an institutional toll-bridge which the rest of society must pay;

Some previous thinkers on demographic energy, locational value, and technology…

Fuller uses as an example of this the Telstar satellite which. while weighing only one-tenth of a ton, out-performs 75,000 tons of transatlantic cable…
… substitution not only in materials but in functions… may vastly alter our lives, effecting how we otherwise spend our energy and time. For example, communications as a substitution for transportation can effect such savings to a great extent…
A society that exercises this option of using communication in place of transportation in many of its activities … can conserve many resources. (Seeking source 081117)

Von Thunen::

r = Y(p − c) − YFm

where R=land rent; Y=yield per unit of land; c=production costs per unit of commodity; p=market price per unit of commodity; F=freight rate; m=distance to market.

Locational rent, a term used by von Thünen in his argument, is to be understood as the equivalent to land value. It corresponds to the maximum amount a farmer could pay for using the land, without making losses. It can be defined as the equation below:

L = Y(P − C) − YdR

* L: Locational rent (in Money / m²)
* Y: Yield (in Units / m²)
* P: Market price of the crop (in Money / units)
* C: Production cost of the crop (in Money / units)
* d: Distance from the market (in m)
* R: Transport cost / Resistance / Friction (in Money / units / m)

Stewart:: Demographic Gravity:

F = (N1 X N2) / ( √d )
Demographic Force = (population 1 X population 2) / (distance squared)

E = (N1 X N2) / d
Demographic Energy = (population 1 X population 2) / distance; this is also Zipf’s determinant:
Interchange of value; Y value of goods exchanged; inter-community movement of goods (by value):
Y = (N1 X N2) / d

PEN1 = N2 / d
Demographic Potential Energy of population 1 = population 2 / distance

PE = N / d
Demographic Potential Energy @ point = population / distance, in persons per mile

Gradient = N / m²
Demographic Gradient = persons / (mile squared)

Force of Diversity: economy of population living at source of raw material production (saves transport to production centre); n+, N-
Force of Unity: Economy of living together in one big city where all production done (saves transport to consumers); n- (to 1), N+ (to 100%)
Conflict of economies: n number of different communities and N sizes;

Reilly’s retail gravity equilibrium::

Population 1 / (distance to balance, squared) = Population 2 / (distance to balance, squared)

Larger cities will have larger Sphere of Influences than smaller ones, meaning people travel further to reach a larger city.

BP = d / (1 + ( √ (m²1 / m²2))

The balance or Break Point (BP) is equal to the Distance (d) between two places, divided by the following: Unity or Total (1) plus the Square Root of, the size of Place One (p1) divided by the size of Place Two (p2).

Notional gravity can be influenced by a number of things, but square footage is simple and effective measure of utility, ceteris paribus.


Interchange of value; Y value of goods exchanged; inter-community movement of goods (by value):

Y = (N1 X N2) / d

The movement of goods by value – and of persons – between any two communities, N1 & N2 that are separated by the easiest transportation distance, d, will be directly proportionate to the product, N1 X N2, and inversely proportionate to the distance, d. (The “Principle of least effort”)
