The floor standing unit generates 3 kW of electrical and 15 kW of thermal energy. [ 23 ] [ 24 ] WhisperGen, a New Zealand firm with offices in Christchurch , has developed an "AC Micro Combined Heat and Power" Stirling cycle engine.
Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car. Thermoelectric generators have been investigated to replace the alternators in cars demonstrating a 3.45% reduction in fuel consumption. [33] Projections for future improvements are up to a 10% increase in mileage for hybrid vehicles. [34]
