basic consept of electrical generator

The electrical generator is somewhat analogous to a water pump, which creates a flow of water but does not create the water inside. The generator moves an electric current, but does not create electric charge, which is already present in the conductive wire of its windings. The construction of a generator is similar to that of an electric motor, and all common types of dynamos could work as motors.

The way in which a turbine-driven generator uses reciprocating motion to produce kinetic energy is similar to the way in which a turbine uses reciprocating motion--driven by gas heat--to produce power in a jet engine. Turbochargers harness engine exhaust heat to propel a turbine-like fan in order to produce high volumes of air, called "boost," which are fed into the internal combustion engine.
