Abstract
The present device provides an in-pipe turbine generator having a conduit, a plurality of runner blades positioned within the conduit, and a pitch adjustment mechanism whereby the pitch of the runner blades may be varied. The pitch adjustment mechanism further includes pitch adjustment screws that are positioned on a tangential flat on the master pitch adjustment bevel gear. Rotation of the pitch adjustment screw rotates the master pitch adjustment bevel gear thereby rotating the blade hub gears and the runner blades. Runner blade torque and angular velocity is transferred to a DC power generator and may be converted to AC power.
