The core innovative technology behind the success of the WhisperGen™ heat and power system is a Stirling external combustion engine.  


The four cylinder Stirling WhisperGen™ heat and power system, first released commercially in 1998, produces electricity and hot water suitable for household use or space heating. A patented mechanism, the Wobble Yoke, transfers the vertical motion of the pistons to the rotary motion of the alternator.
The heat to the engine is provided by a burner. Various burners, developed by Whisper Tech Limited specifically for the WhisperGen™ heat and power system, allow different models to operate on specific fuels including diesel, kerosene and natural gas.
