Abstract:
1. An in-pipe turbine generator comprising: a) a conduit; b) a plurality of runner blades positioned within the conduit; c) a pitch adjustment mechanism positioned within the conduit and accessed through a port whereby the pitch of the runner blades may be optimized for a specific in-pipe turbine generator application by adjusting at least one pitch adjustment screw; d) a means for imparting kinetic energy to the runner blades creating torque and angular velocity comprising the passage of a fluid through the conduit; and e) a means for transferring torque and angular velocity to a DC power generator comprising a generator coupling, a gearbox reduction means, a DC generator, and a means for supporting the gearbox reduction means and the gearbox within the conduit.
