An exemplary embodiment of the invention is a power system for providing power to a critical load. The system includes a first power source producing sufficient power to supply the critical load and a second power source, independent of said first power source. The second power source produces sufficient power to supply the critical load. The system also includes a rotary device having a first power input circuit and a second power input circuit. The second power source is coupled to the rotary device at the second power input circuit. A transfer switch selectively couples the first power source to the first power input circuit and the second power input circuit.
