The generator generates an electromotive force by an electromagnetic induction action and converts mechanical energy into electrical energy. The generator includes a cylindrical stator and a rotor rotatably housed inside the stator. Here, the electromagnet is generally used for the stator and the rotor, and the magnitude of the electromotive force can be freely changed by adding or subtracting the strength of the magnetic force by the increase or decrease of the current. This is used by winding a coil in a slot and flowing a current through it. In addition, permanent magnets may be used. For example, a coil may be wound around a slot inside the stator and a permanent magnet may be coupled to the rotor. Of course, it is also possible that the permanent magnet is coupled to the stator and the coil is wound around the rotor. Such a generator forcibly rotates the shaft on which the rotor is fixed, thereby generating electromotive force by electromagnetic induction between the rotor and the stator. Then, the electromotive force is supplied as an output voltage to the load.

The ship gains its propulsion with a screw or propeller attached to the hull aft, which is powered by a large motor. The screw or propeller spins and flips the water backwards as if the wind is spinning and the ship moves forward with the reaction.
