A switch can connect or disconnect a generator and a supply unit. A control unit controls an engine in one of a plurality of control states including a power generation state, a first standby state and a second standby state. When an acceptance unit accepts a switching instruction from the first standby state to the second standby state, the control unit controls the switch to disconnect the generator and the supply unit, and reduces the engine speed of the engine from an engine speed in the first standby state to an engine speed in the second standby state.

The disclosed embodiments aim to improve upon existing multi stage generators for providing power to a load. In particular, embodiments of the invention include a regulator situated between the output of a pilot exciter and the main exciter of a multi stage generator system, the regulator arranged to limit the voltage available to a field current control element which sets the field current supplied to the main exciter.

A fluid cylinder includes an outer cylinder surrounding expandable intermediate and inner cylinders. A first sealed volume is defined between the outer cylinder and the intermediate cylinder, a second sealed volume is defined between the intermediate cylinder and the inner cylinder and a third volume defined within the inner cylinder. The first sealed volume is held at a lower pressure than the second and third volumes. At upper heights of the intermediate and inner cylinders, the pressures of the second and third volumes are approximately equal. Exerting a downward force on a linkage connected to a top end of the inner cylinder results in changes in pressure-volume relationships, causing the intermediate cylinder to fall and, upon release of the downward force, causing the intermediate and inner cylinders to rise again to their upper heights. The reciprocal motion generated can be harnessed for various purposes.

There is provided a combustion engine and an electric generator. The combustion engine comprises an engine housing, a cylindrical member configured to rotate about an axis within a cavity of the engine housing, a piston, and an engagement section for engaging the piston. The piston is mounted to the engine housing and the engagement section is mounted to the cylindrical member, or the piston is mounted to the cylindrical member and the engagement section is mounted to the engine housing, such that the piston and the engagement section periodically rotate past one another as the cylindrical member is rotated within the engine housing. The piston engages the engagement section as they rotate past one another, the engagement forcing the piston to compress gases in a combustion chamber, which fire to drive the rotation of the cylindrical member. The electric generator may be driven by the combustion engine.
