The Nature of Power
Ernie and Erica WisnerPermaculture Voices, 2015
Ernie's Ocean
Erica's Academy of Physical Arts
In physics, power is the ability to do work. l(Lift weights, overcome friction.)l2nd law of thermodynamics/arrow of time: lThings proceed toward increasing disorder.lLaw of life (and death): Sunlight fuels self-organization.
l Direct, local options: (Minimize distance, transfers, losses, secrets) l Solve 2 problems (Solutions beget new problems)l Prepare for the unexpected
Erica's Law:
A permanent solution to a temporary problem l is a permanent problem.
Power in Permaculture
lUsing what's abundant (surplus/waste/problems)lto generate what's scarce (wants/needs/solutions).
Primitive Technology, two types:l First attempts / prototypes
lFirst choice / locally-evolved and proven
So why don't we stick to ancestral ways?
lTimes change. We adapt.lFossil fuel boom: like “free” whale oillOther resources:
l Radiant gain/loss: solar gain, night-sky cooling, line-of-sight, conduction l Convection & wind: chimney, scoop, State change: evaporate, condensel Local biomass food, wood, biogas, biofuels*l Nesting strategies l zone, insulate, mass/bank, shade, expose
Let's examine some alternatives:
lOff-grid, locally-powered or solid-state.

lTime frames day/season / 5yrs / generationslPersonal resources skills, affinities, toleranceslCommon traps / errors:
l Fads/symbolic gestures: biofuel mandates, tilapia, RMH in a tipi l “Other Guy Knows Best:” l under-estimating unknowns l outside your skillset or experiencel Community tolerancesl “Shoulds” vs. satisfactory solutionsl Too-small circles (self-consumption) l Delusion of “independence”l Illusion that leaving it = saving it.
The most powerful choices reflect knowledge of - the situation - your own nature.
