Mer motorrelaterat än drivmedelsrelaterat kanske, vet inte om denna motor har nämnts här tidigare:

Citat:
The opoc's new opposed piston-opposed cylinder direct gas exchange operation provides the well known emissions benefit of 4-cycle engines, the simplicity benefits of 2-cycle engines, the power density of the less well known opposed piston engine, and the extraordinary developments in computer and thermodynamics all tied together in a new and proprietary engine architecture.

For a given power level, the opoc™ engine is 30-percent lighter, one-quarter the size, and achieves 50-percent better fuel economy compared with a state-of-the-art, conventional turbo-diesel engine. Because of this breakthrough, we are enthusiastic about the internal combustion engine’s future. It’s a breakthrough based on the strength of extraordinary power density.
Samtidigt vet vi att stora fartygsdieslar (tvåtakt) är rätt effektiva. De nämner 50%, 0.50l/mil skulle då bli 0.33 l/mil, hyfsat får man lov att säga. Och detta i en kompakt motor med avsevärt färre rörliga delar.
