System and apparatus for improved turbine pressure and pressure drop control

Abstract

A system for improved power generation through movement of water having a turbine with a generally cylindrical housing, where the turbine is positioned to receive kinetic energy from moving water, and a member positioned circumferentially about the housing for inducing a pressure drop across the turbine. The member may be a rotating blade, cantilevered duct, circumferential flange, radial eductor, and air tube for injection of ambient air into said water source.
