Overview
TERU converts low-grade or waste thermal energy into electricity by dynamically varying supercapacitor capacitance with a thermal gradient — generating current directly from a temperature difference, with no fuel, sunlight, wind, or moving parts. It operates wherever a thermal differential exists (industrial heat, data-center/HVAC exhaust, the sunny/shaded sides of a wind-turbine blade, solar-panel rear zones), recovering parasitic heat that conversion systems normally waste.
Applications
Primary use cases: industrial heat recovery (power plants, smelting, manufacturing); wind-turbine blade integration; solar-panel rear-cooling add-on; data-center/HVAC exhaust capture; remote/gridless electronics and sensors; off-grid backup.
Industries and users: industry, utilities, data centers, renewable operators, IoT.
Scale: standardized modular units; stackable for industrial use, compact for mobile/remote deployments.
Operating Principle
A thermal gradient across supercapacitors changes their capacitance cyclically, displacing charge and producing current — capacitance-driven generation from heat. Passive, self-sustaining, no external power or moving parts.
Limitations: low areal power (~10 W/m²); needs a sustained thermal differential; R&D maturity.
Key Parameters
Energy source: low-grade heat / thermal gradient (ambient, solar, industrial), gradient range 10–100 °C. Module: a standardized, modular footprint suited to both stationary and mobile installations.
Supercapacitor: engineered to deliver strong charge displacement and high instantaneous current pulses through each thermal cycle.
Power output: claimed range is wide and unreconciled — roughly 10 W per square meter of module area (one source) up to multi-kilowatt levels per module (another); to be validated. Efficiency: estimated 15–35 % of available thermal potential. Solid-state, no moving parts; emission-free; passive; no consumables/fuels.
Architecture and Components
Supercapacitor array with thermal-gradient coupling; capacitance-cycling/charge-extraction electronics; surface-mount or structure-integrated module. No external power, no moving parts.
Advantages
Technical: generates from any thermal differential; passive, no moving parts; integrable into turbines, walls, panels.
Economic: minimal CAPEX/OPEX; no maintenance cycles.
Environmental: zero emissions, no fuel or chemicals — just ambient/waste heat.
Strategic: recovers otherwise-wasted parasitic heat across industry, IT, and renewables.
Integrations
Surface-mount or integrate into wind turbines, solar panels, walls, HVAC/data-center exhaust; pairs with ARBOK storage/energy-recovery systems.
Deployment & Operation
Steps: identify thermal differential → mount/integrate modules → connect load/storage. Passive operation; minimal maintenance.
TRL
TRL 3 (confirmed by Michael). Proof-of-concept; components and output tested in lab under thermal gradients. Remaining: stronger prototype validation, then field pilot.
Market Potential
Vast low-grade waste heat goes unrecovered across industry, data centers, and renewables. A passive, modular thermal-capacitance harvester fits distributed recovery and gridless electronics — though low areal power suits niche/integrated use rather than bulk generation.
Typical Project Economics
Minimal CAPEX/OPEX, no maintenance; value from recovered parasitic heat and gridless power for sensors/electronics. Bulk economics limited by ~10 W/m²; best where heat and integration are free. (Indicative until pilot data.)
Risk Factors
Low power density (~10 W/m²) limits bulk use; needs sustained thermal gradient; R&D maturity and field validation; charge-extraction efficiency to confirm.
