Complete Energy Systems: From Muscle Power to Electricity Generation
Energy multiplies human capability. This campaign covers every energy source from animal power through hydroelectric, wind, and solar generation.
Chapter 1: Energy Sources (Ranked by Accessibility)
| Source | Power Output | Reliability | Complexity | Initial Cost | Maintenance |
|---|---|---|---|---|---|
| Human muscle | 75-100 watts sustained | Always available | None | None | Food |
| Animal power (horse/ox) | 500-750 watts sustained | High (if fed) | Low (harness) | Animal cost | Feed + care |
| Flowing water (micro-hydro) | 100-10,000 watts | Very high (24/7) | Moderate-high | Moderate | Low |
| Wind (turbine) | 100-5,000 watts | Variable (30-40% capacity) | High | Moderate-high | Moderate |
| Wood (thermal) | 10,000-50,000 BTU/hour | High (if forest available) | Low | Very low | Harvesting |
| Solar (photovoltaic) | 100-5,000 watts | Daytime only (20-25% capacity) | Low (if panels available) | High | Very low |
| Biogas (methane digester) | 500-5,000 BTU/hour | Moderate (needs feedstock) | Moderate | Low-moderate | Daily feeding |
| Steam (wood-fired boiler) | 1,000-50,000 watts | High (if fuel available) | Very high | High | High (dangerous) |
Chapter 2: Micro-Hydro Power
| Component | Function | Specification | Material |
|---|---|---|---|
| Intake (diversion weir) | Diverts water from stream | Screened, trash rack | Stone, concrete, or wood |
| Penstock (pipe) | Carries water to turbine under pressure | 4-12 inch diameter, as long as needed | PVC, steel, or wood stave |
| Turbine/wheel | Converts water energy to rotation | Pelton (high head), Turgo, or overshot wheel | Metal, wood, or mixed |
| Generator/alternator | Converts rotation to electricity | Car alternator (12V) or permanent magnet generator | Salvaged or purpose-built |
| Controller/regulator | Manages voltage and load | Charge controller + dump load | Electronic (salvaged or built) |
| Battery bank | Stores energy for use | 12V or 24V deep cycle batteries | Lead-acid or lithium |
| Inverter | Converts DC to AC (if needed) | 1,000-3,000 watts | Electronic (salvaged) |
Power calculation: Power (watts) = Head (meters) × Flow (liters/second) × 5.3 (accounting for losses). Example: 10m head × 5 L/s × 5.3 = 265 watts continuous = 6.4 kWh/day. Enough for lights, radio, phone charging, small tools.
Chapter 3: Wind Power
| Component | Function | Specification | Material |
|---|---|---|---|
| Blades (3) | Capture wind energy | 6-12 foot diameter rotor | Wood (carved), PVC, or fiberglass |
| Hub | Connects blades to shaft | Machined or welded | Steel |
| Generator | Converts rotation to electricity | Permanent magnet (axial flux or car alternator) | Magnets + coils |
| Tower | Elevates turbine above obstacles | 30-60 feet (higher = more wind) | Steel pipe, wood, or guyed |
| Tail vane | Points turbine into wind | Flat plate on boom | Sheet metal + pipe |
| Furling mechanism | Protects in high wind | Tilts or turns turbine out of wind | Mechanical (spring or gravity) |
| Controller + batteries | Same as hydro system | Charge controller + dump load + batteries | Electronic |
Minimum wind speed: 4 m/s (9 mph) average for viable wind power. Power increases with CUBE of wind speed (double speed = 8× power). Site on hilltop or above tree line.
Chapter 4: Biogas (Methane Digester)
| Component | Function | Specification | Material |
|---|---|---|---|
| Digester tank | Anaerobic decomposition chamber | 200-2,000 gallons | Concrete, plastic, or steel (sealed) |
| Inlet | Feed organic material | Pipe with funnel | PVC or concrete |
| Outlet | Remove spent slurry (fertilizer) | Overflow pipe | PVC or concrete |
| Gas storage (gasometer) | Collect and store biogas | Floating drum or bag | Steel drum in water, or plastic bag |
| Gas line | Deliver gas to point of use | 1/2-1 inch pipe | PVC or steel |
| Burner | Cook or heat with biogas | Modified propane burner | Steel (larger orifice than propane) |
| Mixing/agitation | Prevent crusting, improve gas production | Manual stirring rod or recirculation | Steel rod through sealed bearing |
Feedstock: Animal manure (cow = best), food waste, crop residue. Mix 1:1 with water. Temperature: 35-40°C (mesophilic) for best gas production. Retention time: 20-40 days. Output: 1 cow's daily manure → 1-2 hours of cooking gas.
Chapter 5: Battery and Electrical Systems
| Component | Function | Specification | Safety Notes |
|---|---|---|---|
| Batteries (deep cycle) | Store energy | 12V, 100-200 Ah each | Ventilate (hydrogen gas). Keep upright. |
| Charge controller | Prevents overcharge | PWM or MPPT, matched to system voltage | Required. Overcharge = battery damage/fire. |
| Inverter | DC to AC conversion | Pure sine wave, 1,000-3,000W | Modified sine wave damages some electronics |
| Fuses/breakers | Overcurrent protection | At every connection point | CRITICAL safety. Batteries can deliver 1,000+ amps. |
| Wire sizing | Carry current without loss/heat | Larger wire for longer runs and higher current | Undersized wire = fire hazard |
| Grounding | Lightning and fault protection | Copper rod driven 8 feet into earth | Required for safety |
| Dump load | Absorbs excess energy | Water heater element or resistor bank | Prevents overcharge when batteries full |
Chapter 6: Energy Budget Planning
| Load | Watts | Hours/Day | Wh/Day | Priority |
|---|---|---|---|---|
| LED lighting (4 rooms) | 40 | 5 | 200 | Essential |
| Phone/radio charging | 10 | 4 | 40 | Essential |
| Water pump (small) | 100 | 2 | 200 | High |
| Refrigerator (efficient) | 60 | 12 | 720 | High |
| Power tools (intermittent) | 500 | 1 | 500 | Moderate |
| Laptop/computer | 50 | 4 | 200 | Moderate |
| Washing machine | 500 | 0.5 | 250 | Low |
| Total (all loads) | - | - | 2,110 Wh/day | - |
To supply 2,110 Wh/day: Need ~300W continuous generation (micro-hydro ideal) OR 1,000W solar array (accounting for 4-5 peak sun hours) OR 500W wind turbine (at 30% capacity factor).
Reference Card
- Micro-hydro: most reliable off-grid power. 24/7 generation. Power = Head(m) × Flow(L/s) × 5.3.
- Wind: viable above 4 m/s average. Power = cube of wind speed. Height matters enormously.
- Solar: 4-5 peak sun hours/day typical. Need 3-5× your daily Wh in panel watts to account for losses.
- Batteries: deep cycle only (not car batteries). Keep above 50% charge for longevity. Ventilate (hydrogen gas).
- Wire sizing: voltage drop kills efficiency over distance. Use larger wire for long runs. 12V systems need very thick wire.
- Safety: fuse EVERYTHING. Batteries can deliver thousands of amps (welding-level). Short circuit = fire.
- Biogas: 1 cow's manure = 1-2 hours cooking gas daily. Must be sealed anaerobic. 35-40°C optimal.
- Start small: lights + phone charging (250 Wh/day) is achievable with tiny system. Expand as needed.
