An integrated engine and generator is provided and includes a stationary non-rotating shaft. An engine block is provided that is capable of rotation about the shaft. The engine block comprises a plurality of cylinders with each cylinder including a piston translating in rectilinear motion while rotating about the shaft. A stationary generator housing and stator surrounds the block and has stator windings wound into the housing. Magnets are affixed to an outer surface of the block to rotate with the block, with the magnets separated from the housing by an air gap. The stator windings are electrically configured to match pole pairs of the magnets in order to generate electrical current upon block rotation.
