Breakthrough in heat engine scalability
GREC's layered WGV geometry enables heat transfer surface to scale proportionally with work generating volume, eliminating the fundamental scaling problem in conventional heat engines where surface area increases with r² while volume increases with r³. This means GREC maintains high efficiency even when scaling up to larger units, while competing technologies suffer from degraded performance at larger sizes.
The larger the Work Generating Volume (WGV) → the more energy. Surface scales with volume!
The greater the temperature gradient → the more efficiency. Works from 80°C to 500°C+.
Low-tech design with few moving parts. Lower manufacturing costs, minimal maintenance.
Constructed from recyclable materials like aluminum. Environmentally responsible from start to finish.
Quick thermal response time enables flexible operation based on available heat and energy demand.
From kW to MW scale—much higher than typical Stirling engines (usually <100kW).
Small, light, and compact
Where there are high temperature differences, GREC can be made small and compact. Ideal for:
Large stationary units
At lower temperature differences, GREC can be built in very large stationary units with larger work generating volume. Perfect for:
A lower temperature gradient delivers lower thermal efficiency, which can be compensated by a larger Work Generating Volume (WGV). This gives high economic efficiency when the heat gradient comes at low or no cost (such as waste heat, solar, or geothermal sources).
