A submersible liquid-vapor generator (LVG) includes an evaporator portion in heat transfer communication with a heat energy source. The LVG also includes a magnetic field apparatus coupled in flow communication with the evaporator portion. The LVG further includes a condenser portion coupled in flow communication with the magnetic field apparatus. The LVG also includes a hybrid working fluid including nanoparticles. The evaporator portion, the magnetic field portion, and the condenser portion at least partially define a hybrid working vapor flow path. The LVG further includes an electrically non-conductive wick structure coupled in flow communication with the evaporator portion and the condenser portion. The wick structure at least partially defines a hybrid working liquid flow path extending between the condenser portion and the evaporator portion.
