The power system of claim 1 wherein said second power source comprises an on-site generator.

Claim 5

The power system of claim 1 wherein said second power source comprises a fuel cell.

Claim 6

The power system of claim 1 wherein said rotary device comprises a rotary condenser.

Claim 7

The power system of claim 1 wherein a third power source is coupled to said rotary device.

Claim 8

The power system of claim 6 wherein said third power source is parallel connected with said first power source at the first power input circuit.

Claim 9

The power system of claim 6 wherein said third power source is parallel connected with said second power source at the second power input circuit.

Claim 10

The power system of claim 6 wherein said third power source comprises a flywheel.

Claim 11

A power system for providing power to a critical load, the system comprising: a first power module including: a first power source producing sufficient power to supply the critical load; a second power source, independent of said first power source, said second power source producing sufficient power to supply the critical load; a rotary device having a primary power input circuit and a secondary power input circuit; said second power source coupled to said rotary device at said secondary power input circuit; and, a transfer switch for selectively coupling said first power source to said primary power input circuit and said secondary power input circuit; and; a second power module including: a first power source producing sufficient power to supply the critical load; a second power source, independent of said first power source, said second power source producing sufficient power to supply the critical load; a rotary device having a primary power input circuit and a secondary power input circuit; said second power source coupled to said rotary device at said secondary power input circuit; and, a transfer switch for selectively coupling said first power source to said primary power input circuit and said secondary power input circuit.

Claim 12

A power system for providing power to a critical load, the system comprising: a first power module including: a first power source producing sufficient power to supply the critical load; a second power source, independent of said first power source, said second power source producing sufficient power to supply the critical load; a rotary device having a primary power input circuit and a secondary power input circuit; said second power source coupled to said rotary device at said secondary power input circuit; and, a transfer switch for selectively coupling said first power source to said primary power input circuit and said secondary power input circuit; and; a second power module including: a first power source producing sufficient power to supply the critical load; a second power source, independent of said first power source, said second power source producing sufficient power to supply the critical load; a rotary device having a primary power input circuit and a secondary power input circuit; said second power source coupled to said rotary device at said secondary power input circuit; and, a transfer switch for selectively coupling said first power source to said primary power input circuit and said secondary power input circuit.
