TURBINE CURRENT GENERATOR

A turbine current generator includes a hollow bearing cylinder to be engaged inside a pipe or a duct for the transit of a fluid, in particular a fluid transit duct deriving from the drilling or exploration of an oil field; a hollow rotating cylinder rotatably and coaxially engaged inside the bearing cylinder and defining a respective transit cylindrical chamber for a fluid. The bearing and rotating cylinders defining at least a cylindrical gap; one or more magnetic or electromagnetic components operatively engaged to the bearing cylinder and/or to the rotating cylinder to generate at least one electric current during the rotation of the rotating cylinder inside the bearing cylinder; an impeller or impellers arranged in the chamber of the rotating cylinder according to positions aligned along a longitudinal axis of the latter, the impellers engaged inside the rotating cylinder to rotate integrally with the latter upon the action of a fluid.
