Three variable gear assemblies called Transgears, an electro-mechanical rotary frequency converter, and a variable overlap generator (VOG), may be used independently and together to provide constant frequency and voltage output power from variable input water flow and wind speed. Two sets of three variable spur/helical gear assemblies of sun and planetary gear sets are combined in a mechanical three variable control to form an assembly called a Hummingbird. A Hummingbird control may comprise a constant speed control motor and a constant speed generator to produce required constant frequency and voltage. In order to provide a constant control input, a constant rotational speed can be produced by a control motor. Once a constant rotational speed is produced, a constant electric frequency and constant AC voltage can be produced by the variable output generator.
