Competitive Advantage


Our unique organic Rankine cycle (ORC) heat engine brings high thermal efficiency to small engines.  It has a much higher expansion ratio than scroll and screw expander solutions.  As a result, it converts more of the energy in a high pressure gas to useful power.  It is ideally suited to small scale applications (under 20kW).


Our engine is simple and uses only conventional manufacturing methods and materials.  It can thus be produced in high volumes at low cost.


Our engine is remarkably compact – very important in automotive and home applications.
