Abstract
According to one embodiment of the invention, a system for power generation inside a steering tool includes a drive system having a drive shaft disposed within a wall of the steering tool, a rotating shaft rotatably coupled to a non-rotating sleeve of the steering tool, and a spline coupled to the rotating shaft. The spline is operable to indirectly drive the drive shaft by directly coupling to an idler gear of the drive system.
