http://en.wikipedia.org/wiki/Rolls-Royce_WR-21

The WR-21 is the first aeroderivative gas turbine to incorporate compressor intercooling and exhaust heat recuperation (ICR) technologies that deliver low specific fuel consumption across the engine's operating range.[2] It offers a reduction in fuel burn of 30% across the typical ship operating profile.[3]

* The intercooler cools air entering the high pressure compressor, reducing the amount of energy required to compress the air.[2]
* The recuperator preheats the combustion air by recovering waste energy from the exhaust, improving cycle efficiency and reducing fuel consumption.

Specific fuel consumption: ~190 g/kWh

Huh...Az MZ ennél kétszer többet kér. :-)
