This paper endeavors to make clear the scope, breadth, diversity, and complexity of the power generation technical area insofar as Air Force interests are concerned. This will be done by presenting the non-functional character of power generation and the non-uniformity of specifying state-of-the-art. There follows an outlining of a means of categorization which encompasses power generation technology, functional subsystems and equipment, systems, and agencies influential upon power generation technology. A general approach to specifying power generation State of Technology will be suggested from the categorization
