The difference between a super charger and a turbocharger is the super charger is a pump bolted on to the engine being driven by shaft power.
A turbocharger is a heat engine. A brayton cycle engine.
The brayton cycle is purely driven by waste heat from the diesel cycle.
A turbodiesel is a combinded cycle heat engine, more efficient than a diesel cycle with an extra pump attached.
Later I will tell why a turbine driven alternator would suck.
