In Topic: The smart metal Nitinol

I guess sapan soni means an engine based around a nitinol element than alternates between austenitic and martensitic forms, then this translational motion is converted into rotational motion mechanically. It would require an electrical supply to function, putting it into competition with conventional electrical motors, which I doubt it would compete with. And anyway, it would have the same existing problems electrical energy storage.
In Topic: Piston-Engined Aircraft

The main reason is that different engines have differing fuel efficiencies in take off/landing and cruising. Piston engines are more efficient at the former, turbofans at the latter. Turboprops are in the middle. So piston engines are used for short ranged, turboprops for medium distance and jet engines for longer distances.
