1. A propulsion system comprising:
a propulsion device;
an engine to selectively power the propulsion device;
a variable torque motor/generator/transmission to selectively power the propulsion device, the variable torque motor/generator/transmission comprising:
a first stator and a second stator, wherein the second stator is spaced apart from the first stator, and
an interactive field element configured to translate so as to selectively engage at least one of the first stator, the second stator, or neither of the first stator nor the second stator;
an energy storage device to store energy for powering the variable torque motor/generator/transmission; and
a controller to selectively operate the propulsion system in a first mode where the variable torque motor/generator/transmission supplies power solely to the propulsion device, and a second mode where the engine supplies power to both the propulsion device and the variable torque motor/generator/transmission, where the variable torque motor/generator/transmission supplies energy for storage in the energy storage device when the propulsion system is operated in the second mode.
