ABSTRACT:
A method and apparatus that uses the flow of drilling fluid to generate electrical energy in a downhole environment. A substantially cylindrical housing comprises a wall having an inlet, an outlet, and a hollow passageway therebetween. A flow of drilling fluid through the hollow passageway actuates a generator located therein, such that the generator generates electricity to power downhole tools, sensors, and networks. The miniaturization of the generator within the housing wall facilitates an unobstructed flow of drilling fluid through the central borehole of a drill string, while allowing for the introduction of tools and other equipment therein.
