Abstract
A fluid-driven alternator for use in a downhole well bore having fluid flowing therethrough includes a housing and an internal impeller rotatably mounted in the housing. A stator and rotor are mounted within the housing, and the internal impeller is coupled to the rotor. Fluid flowing through the housing rotates the impeller which in turn rotates the rotor. A flow diverter can be provided to direct fluid into the housing.
