A continuous power system assembly is provided that includes an integrated shaft-driven unit. The unit contains a turbine, an alternator, a flywheel and a feed pump, all of which are coupled to the shaft. During various modes of operation, any of the turbine, alternator or flywheel may provide the torque used to drive the shaft. When the alternator is not providing the necessary torque to drive the shaft, it is operated as a generator that provides back-up power to a load. The present invention also includes a unique nozzle design that improves the ease with the nozzles may be manufactured in comparison to known designs. The nozzle is manufactured as two halves which are mated as part of the manufacturing process. The individual nozzles may, because only half of the nozzle segments exist on either half of the nozzle block, be easily manufactured using conventional machining.

A rotordynamic system includes a vertically arranged motor, rotordynamic device and controller. The rotordynamic device is a centrifugal pump or compressor operated by the motor to drive a fluid from the input to the output. A liquid cooling system operates to maintain the controller and motor at a desired operating temperature. Due to the liquid cooling system, the controller operates the motor at effectively any practical speed. The liquid cooling system is in heat exchange relationship with an oil system contained within the motor to distribute thermal energy therebetween to further increase thermal control of each.

A continuous power system accumulator assembly is provided that stores thermal energy as sensible heat and minimizes the amount of thermal energy wasted by the system. The assembly includes an accumulator at its core. A preheater assembly is wrapped around the accumulator such that it may absorb heat radiated and conducted from the accumulator. An evaporator is wrapped around the preheater so that most of the heat that is radiated and conducted from the preheater is utilized to heat the vaporizer. The outer housing of the assembly may be a double-walled housing having a layer of insulation located between the two walls. This configuration minimizes heat losses by the assembly.
