Overview
ARBOK-LIQUID GEN is a compact electrical generator using liquid-metal electromagnetic induction — no copper windings, no mechanical rotation. A conductive liquid (Galinstan) is pumped through a static, non-uniform magnetic field, inducing an EMF along the flow (Faraday's law), with no moving solid parts. Deliberately non-hyped: classical electrodynamics, no exotic materials or high-speed rotors — prioritizing reliability, silence, low maintenance, and workshop-level manufacturability.
Applications
Primary use cases: stationary/semi-stationary distributed power where robustness, silence, and low maintenance matter more than size/mass.
Industries and users: off-grid/niche power, research, resilient installations.
Scale: ~1 kW prototype; linearly scalable by tube count, field, flow, or module stacking.
Operating Principle
Conductive Galinstan is pumped (no rotor) through regions of varying magnetic intensity; the moving conductor in the field gradient induces a potential difference between electrodes along the tubes. Liquid replaces copper windings; static field replaces rotor; pump replaces rotation.
Limitations: power density lower than rotating generators; pump reliability sets MTBF; magnet cost dominates CAPEX.
Key Parameters
Stator: an array of parallel non-magnetic tubes, sized to a proprietary geometry. Medium: Galinstan (Ga–In–Sn) liquid-metal alloy. Magnets: high-strength permanent magnets arranged in a non-uniform field geometry. Flow: moderate pumped circulation with modest pump power draw. Output: approximately 1 kW at a voltage/current suited to standard rectification and grid-tie electronics, in a compact housing.
Electrical conversion efficiency is very high, with the small resistive losses in the liquid conductor; overall system efficiency is dominated by the pump's own power draw rather than by conversion losses.
Architecture and Components
Tube-array stator (Galinstan flow); high-strength permanent-magnet system (non-uniform field); pump loop with bubble removal; electrodes + power electronics. No shafts, bearings, rotors, or brushes.
Advantages
Technical: no mechanical wear (only the liquid moves); silent; no copper windings/laminated cores; classical, transparent physics.
Economic: workshop-level fabrication; prototype ~€13 600 (magnets dominate).
Environmental: Galinstan is non-toxic (vs mercury).
Strategic: robust, low-maintenance distributed power.
Integrations
Pairs with ARBOK storage/generation (Binary Battery, Long Battery Air); stationary distributed power; standard electrical interface.
Deployment & Operation
Steps: build tube/magnet/pump assembly → fill Galinstan → operate. Stationary; pump-defined maintenance; silent.
TRL
TRL 3 (concept-stage validation). Concept validated by physics and preliminary calculations. Remaining: lab prototype for electrical verification and long-duration testing.
Market Potential
Niche/distributed silent power where rotating generators' wear and noise are drawbacks. Modest market given lower power density, but valuable for robustness-critical stationary uses.
Typical Project Economics
Prototype cost approximately €13,600 total, with the permanent-magnet system the dominant cost component. Costs fall with magnet reuse, alternative alloys, and scaling.
Risk Factors
Galinstan cost and long-term material compatibility; magnet-dominated CAPEX; pump reliability (MTBF); low power density; concept-stage validation needed.
