Dynamically self-balanced fluid turbine

A reaction turbine system comprising:

• a casement being bilaterally symmetrically arranged about a casement plane containing an orientation axis extending substantially from a first endplate to a second endplate, the first and second endplates being parallel and spaced apart relative to orientation axis;
• a first reaction turbine offset from the casement plane and configured to receive fluid flow from the casement to drive a first reaction turbine rotor rotating with a first spin orientation in a plane perpendicular to an orientation axis producing a first torque about the orientation axis;
• a second reaction turbine symmetrically offset from the casement plane relative to the first reaction turbine and configured to receive fluid flow from the casement to drive a second reaction turbine rotor rotating in a second spin orientation opposite the first spin orientation producing a second torque about the orientation axis;
• and
• a first casement pivot attached at the first endplate allowing the casement to rotate relative to the first casement pivot about the orientation axis in response to the first and second torques.
