===== Systematic Review of Operations and Components =====

Lazarus Forge is a modular, AI-driven unit (3-4 ft³, $1,500-$2,000) that processes 100 tons/day of mixed waste into outputs like vintage tubs ($1K), car kits ($10K), washers ($500), or habitat parts. It uses mechanical, thermal, electromagnetic, and biological mechanisms for destruction (shredding, melting, digestion) and rebuilding (extrusion, printing, welding). Below is a step-by-step outline of physical mechanisms, components, and ideas, designed for new people to grasp the system's flow. Each stage includes end goals, varied applications (e.g., Earth landfills vs. asteroid mining), and light ideological ties.

====== 1. Input and Waste Intake ======
* '''Physical Mechanism''': Mechanical conveyance draws in waste via gravity-fed hoppers or belts, with sensors scanning for composition (e.g., density, spectral signatures) to route materials. Vibration or air pulses prevent clogs.
* '''Components''': Hopper (steel or HDPE, $200, 50-100 kg capacity), conveyor belt ($500, 1-2 m length), sensors (LiDAR/spectrometry, $2K for 95% accuracy), AI controller (Raspberry Pi, $50) for real-time categorization.
* '''Ideas for Optimization''': Modular intake ports for varied waste (e.g., liquid biomass vs. solid metals). In space, use robotic arms ($500) for regolith scooping.
* '''End Goal/Varied Applications''': Prepare 100 tons/day for processing without jams; on Earth, handles landfill mix; in asteroids, intakes iron-rich debris. Ideologically, this stage symbolizes "awakening" waste's potential.
* '''Time/Cost''': 1-2 minutes/ton; $700 total.

====== 2. Shredding ======
* '''Physical Mechanism''': Rotary torque (1-2 hp motor) shears materials into 1-5 cm pieces, breaking molecular bonds via mechanical force. Metals endure high shear (500 MPa); plastics/biomass use grinding (20-50 MPa).
* '''Components''': Hybrid shredder ($700, dual-mode blades for metals/plastics, 5-10 kg/hour), safety enclosure ($200) to contain debris.
* '''Ideas for Optimization''': Variable speed (100-500 RPM) for material type; add water jets ($200) for dust suppression in biomass.
* '''End Goal/Varied Applications''': Uniform particles for sorting (volume reduction 50-70%); Earth: Preps landfill organics; asteroids: Breaks regolith for metal extraction. Ties to ideology: "Destruction" as the first step in rebirth.
* '''Time/Cost''': 2-5 minutes/10 kg; $900 total.

====== 3. Sorting (Magnetic Separation Upfront) ======
* '''Physical Mechanism''': Electromagnetic induction (0.1-0.5 T fields) generates Lorentz forces to separate metals—magnets pull ferrous (steel/iron), eddy currents repel non-ferrous (aluminum/copper). NIR optics scan plastics/biomass by infrared absorption.
* '''Components''': Overbelt magnets/eddy current separator ($1K-$2K, 95% efficiency), NIR scanner ($2K), air classifiers ($1K) for light organics like biomass.
* '''Ideas for Optimization''': AI integration ($500) for adaptive sorting (e.g., 98% accuracy on mixed waste); mild sorting mode tolerates 5-10% inerts for bioreactor input.
* '''End Goal/Varied Applications''': Divert metals (20 tons/day) to purification, biomass/plastics to reactors; Earth: Prevents reactor contamination; asteroids: Isolates iron-nickel from silicates. Ideologically, "separation" mirrors discerning value from waste.
* '''Time/Cost''': 1-2 minutes/ton; $4K total.

====== 4. Biomass Reactor (Stage 1, Dyson-Inspired Anaerobic Digestion) ======
* '''Physical Mechanism''': Biological decomposition in a sealed, low-oxygen environment (35-55°C)—bacteria perform hydrolysis (breaking polymers), acidogenesis (fermentation to acids), acetogenesis (acids to acetate), and methanogenesis (acetate to methane). Agitation mixes contents for uniform reaction.
* '''Components''': Vertical reactor (concrete/steel, $100K pilot, $1M full, 20-40 ton capacity), mixing paddles ($500), gas collector ($1K), heat exchangers ($2K) from biogas/solar.
* '''Ideas for Optimization''': Mild sorting allows 5-10% inerts (plastics skimmed as scum); integrate magnetic pre-sort to avoid metal contamination (10-20% yield drop).
* '''End Goal/Varied Applications''': Convert 40 tons/day biomass to biogas (5,000-10,000 kWh/day, $500-$1,000) and digestate (20-30 tons/day fertilizer, $10-$20/ton); Earth: Energy for units; asteroids: Process organic residues. Ideologically, "fermentation" as organic revival into energy.
* '''Time/Cost''': 20-60 days/cycle; $1.1M full.

====== 5. Plastics Processing (Stage 2, Pyrolysis for Fuel) ======
* '''Physical Mechanism''': Thermal decomposition (400-600°C, low oxygen) breaks polymer chains into hydrocarbons via cracking and depolymerization, yielding gases/liquids (gasoline 30-40%, diesel 40-50%, wax 5-10%).
* '''Components''': Pyrolysis reactor ($10K pilot, $100K-$1M full), condenser ($2K) for liquids, emissions scrubber ($5K).
* '''Ideas for Optimization''': Use AD scum (80-90% plastics recovery) as input; mild biomass mix tolerated but slows (10-20%)—pre-sort with flotation ($2K).
* '''End Goal/Varied Applications''': Turn 10 tons/day (or 2-5 tons post-competition) into fuels/wax ($5K-$10K/day); Earth: Power units; asteroids: Fuel analogs from trace polymers. Ideologically, "distillation" refines waste into usable energy.
* '''Time/Cost''': 1-2 hours/ton; $110K pilot.

====== 6. Metals Purification (Spin Chamber Focus) ======
* '''Physical Mechanism''': Induction heating (eddy currents, 2,700°F) melts metals; centrifugal spin (100-500 RPM, 0.5-5 G) stratifies by density (heavy metals outward, light slag inward); electro-migration (1-5 A/cm² DC) moves ions (e.g., copper to cathode, silicon to anode via quasi-electrolysis); Lorentz forces (0.5-2 T magnetic fields) stir/dampen flow for precision. Wire extrusion uses electromagnetic pinch (0.8-1.5 T coil) to stabilize stream.
* '''Components''':
* '''Induction Coils''': Copper windings ($200-$500, 2-5 kW) for melting.
* '''Spin Chamber''': Rotating vessel (200-500 RPM, motor $500) with DC electrodes (graphite, $50-$100, anode ring/center, cathode die/wall).
* '''Magnetic System''': Neodymium coils/magnets ($500-$1K, 0.5-2 T) for stirring/braking.
* '''Extrusion Die''': Ceramic (alumina/zirconia, $200, conical with embedded coils) for wire pull (1-2 mm, 0.5-2 m/min).
* '''Outer Shell''': Non-ferrous, non-conducting, high-temp material like alumina ceramic (Al2O3, melting point ~2,050°C, thermal conductivity <30 W/m·K, electrical resistivity >10^14 Ω·m) or zirconia (ZrO2, ~2,700°C, similar properties). These ceramics are ideal—non-reactive with molten metals, withstand 1,000-1,500°C operations, and insulate induction fields. Alternatives: Silicon nitride (Si3N4, ~1,900°C, non-wetting) or silicon carbide (SiC, ~2,700°C, but semi-conducting—avoid if full insulation needed). Shell thickness: 5-10 cm for structural integrity, with cooling channels (water, $200).
* '''Ideas for Optimization''': Variable fields (pulsed 3-10 T) for targeted migration; integrate with asteroid extrusion (conical heads on probes). Boosts purity from 97-98% to 99.9-99.999% in one pass.
* '''End Goal/Varied Applications''': Purify 20 tons/day (5-15 min/10 kg), extrude wire for welding/printing; Earth: High-quality brackets ($20-$50); asteroids: Iron-nickel wire for habitats. Ideologically, "purification" as refining waste's essence.
* '''Time/Cost''': 5-15 min/batch; $2K-$3K module.

====== 7. Fabrication and Output ======
* '''Physical Mechanism''': Welding (arc/MIG, 1-5 kW) fuses parts; 3D printing layers materials (laser/heat fusion).
* '''Components''': Robotic welder ($500), 3D printer (hybrid DMLS/FDM, $5K), assembly arms ($500).
* '''Ideas for Optimization''': AI ($50) for generative designs; self-replication prints new units ($500 each).
* '''End Goal/Varied Applications''': Produce goods ($5K-$20K/day), replicate (1 to 1,000 in 3-5 years); Earth: Tubs/car kits; space: Propulsion motors (100-400 kg, 2030-2040). Ideologically, "forging" completes the revival cycle.
