WhisperGen

The core innovative technology behind the success of the WhisperGen™ heat and power system is a Stirling external combustion engine. The WhisperGen™ is developed by Whisper Tech Limited in Christchurch, New Zealand.

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, natural gas and LPG.

WhisperGen's are currently being mass produced by Efficient Home Energy (EHE) in Spain.

EHE is a joint venture between two partners: Whisper Tech Limited, a subsidiary of the New Zealand company Meridian Energy Ltd., which holds 40% of the capital; and the Mondragón Corporation, holding the remaining 60% through its Components Division, Fagor Electrodomésticos, Mondragón Inversiones and Mondragón Innovación.
