Power — Energize
How does my Ark generate and store energy?
The Backup Rack
Layered emergency power as the last-resort combustion and mechanical backup when the Sun Bank is depleted and the sun is not cooperating.
FootprintUtility area or shedYieldEmergency / short-term powerCycleTest monthly or quarterly (exercise generators, check fuel, rotate stocks); use only when Sun Bank + Efficiency discipline + The Burn are not enough.
The Burn
Rocket mass heater as the primary combustion-based heat source. Extreme wood efficiency (often 90%+ less wood than a conventional stove), 24-hour radiant heat from the thermal mass, and ability to cascade waste heat into water heating or cooking.
FootprintLiving room or central spaceYieldWhole-house or primary living space heatCycle1 fire per day (or every other day in mild weather)
The Efficiency Audit
A structured, recurring process (not a one-time project) to measure, label, and ruthlessly reduce every energy and water demand before you ever add more generation or storage. This is the first fuel of the entire Power (and Well) domain.
FootprintProcess + documentationYieldReduced demand across the boardCycleAnnual deep review + spot checks after any new appliance, insulation work, or behavior change; monthly quick scans of the highest-draw items.
The Sun Bank
Solar panel array with battery storage as the primary renewable generation and storage rig. MPPT controllers, battery bank (LiFePO4 preferred), inverter, and includes solar thermal for water heating where it makes sense.
