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.
Experimental Mid-stage Ancient
Passive solar Hoop houseGlass/trombe
Sears catalog homes, sunrooms, shade porches
Courtyards, caves, solar bowls, terraced cities
Cooling / refrigeration
Ground tubesSwamp coolersPits/streams
Root cellarsShade trellisesSwamp coolers
Yakhchal/ice pits, wind catchers, fountains, qanat
Heating Pocket rocket, woodstove, cave hearth
Rocket mass heaters, geothermal
Hot rocks:Ondol, k'ang, kachelofen, tawakhenah, hypocaust

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.
