[ What is claimed is:] [1.]1. A heat exchanger for increasing the mass flow of combustion air in a power generation system, comprising:a cold side flow path through which combustion air flows after compression by an air compressor and before entering a combustion chamber;means for increasing the temperature of the combustion air as it flows through the cold side flow path;means for introducing a first amount of fluid into the cold side flow path at a first point;means for evaporating the first amount of fluid at a first location within the cold side flow path;means for introducing an additional amount of fluid into the cold side flow path at one or more additional points located appreciably downstream of said first point; and means for evaporating at least a portion of the additional amount of fluid at a second location within the cold side flow path. [5.]5. A heat exchanger for increasing the mass flow of combustion air in a power generation system, comprising:a hot side flow path;a cold side flow path through which combustion air flows, at least a portion of the cold side flow path being adjacent to and thermally coupled with the hot side flow path;means for introducing fluid into the cold side flow path at a location within said portion of the cold side flow path that is adjacent to and thermally coupled with the hot side flow path; andmeans for evaporating the fluid within the cold side flow path. [10.]10. A heat exchanger for increasing the mass flow of combustion air in a power generation system, comprising:a plurality of modules located between an air compressor and a combustion chamber, anda plurality of fluid introduction devices, each module further comprising a cold side flow path having an entrance and an exit, said cold side flow paths being indirectly coupled to one another, wherein at least one of said fluid introduction devices is located approximately at the entrance to the cold side flow path of at least one module.11. A heat exchanger as in claim 10, wherein the cold side flow paths of said modules are coupled to one another in series via ducting.12. A heat exchanger as in claim 10, wherein the cold side flow paths of said modules are coupled to one another in parallel via ducting.13. A heat exchanger as in claim 10, wherein the plurality of fluid introduction devices are chosen from the group including nozzles, orifices, misters, and foggers.14. A heat exchanger for increasing the mass flow of combustion air in a power generation system, comprising:a heat source;a cold side flow path through which combustion air flows, at least a portion of the cold side flow path being adjacent to and thermally coupled with the heat source; anda fluid introduction device disposed within said portion of the cold side flow path that is adjacent to and thermally coupled with the heat source.15. A heat exchanger as in claim 14, wherein the heat source is chosen from the group that includes: a hot side flow path through which hot exhaust gases pass, a solar array, heat-dissipating electrical components, heat-dissipating lining of combustion components, and light. [16.]16. A heat exchanger, comprising:an enclosed hot side air flow passage;an enclosed cold side air flow passage adjacent to and in thermal communication with the hot side flow passage;a fluid source, coupled to a fluid distribution system, distributing fluid to one or more fluid introduction devices located within the cold side air flow passage at a location therein that is adjacent to and thermally coupled with the hot side air flow passage, and providing micronized fluid into the cold side air flow passage.17. A heat exchanger system, comprising:a plurality of heat exchangers as in claim 16 coupled in series. [18.]18. A heat exchanger system, comprising:two or more heat exchangers, each having an enclosed hot side air flow path and an enclosed cold side air flow path, said flow paths thermally coupled with each other, the heat exchangers configured to be arranged in series, with the cold side air flow path of a first heat exchanger connecting to the cold side air flow path of a next heat exchanger,a fluid source, coupled to a fluid distribution system, distributing fluid to one or more fluid introduction devices located at the entrance to the cold side air flow path of each heat exchanger and providing micronized fluid into the cold side air flow path.
