Abstract
The disclosed embodiments include systems and methods to improve downhole drilling. A representative system may include a geostationary portion (e.g. a valve assembly) and a turbine coupled to the geostationary portion to cause counter-rotation of the geostationary portion relative to a drillstring in a default state. A generator that is also operable to act as a motor is coupled to the turbine, and is also coupled to a controller and an energy that may harness any excess energy generated by the turbine when the turbine is able to counter-rotate the geostationary portion at a faster rate than needed to maintain the geostationary portion in a rotationally static condition relative to the wellbore.
