Abstract
A turbine for generating electric power when exposed to a fluid source, such as a liquid or gaseous current. The turbine has two substantially annular rotor housings spaced in parallel, horizontal planes. Each housing is provided with a plurality of radially extending blades which are connected to coaxial shafts. One of the shafts is connected to the field windings of an electric generator while the other shaft is connected to the armature windings. The radial blades in each rotor housing when exposed to the liquid or gaseous current rotate in opposite directions causing the field and armature windings of the generator to rotate in opposite directions to increase the power output of the generator. Fluid scoops are located at the entrance to each housing to accelerate the fluid current and deliver it to curved stator blades which form a series of fluid jets which further accelerate the incoming fluid and bend the fluid so as to direct it to impinge on the radial rotor blades in a direction providing increased starting torque while also increasing the effective force of the fluid. This increased effective force is added to the internal force of the fluid once operation is commenced so that the scoops and stator blades insure power output in light fluid currents and multiply power output in heavy currents.
