Abstract
A turbine has a hollow conical rotor sealed by a base end cap. The outer race of a bearing is centered and mounted on the end cap. An intake shaft mounted within the bearing's inner race passes through the race. High-pressure fluid introduced into a passage within the intake shaft passes through a nozzle arm and nozzle mounted on the intake shaft within the interior of the rotor and is directed by the nozzle against the inner surface of the rotor. Friction and adhesion between the fluid and the inner surface transfers kinetic energy to the rotor, causing it to rotate. Fluid is exhausted from the interior of the cone through a passage in an output shaft attached to the apex of the rotor. Mechanical power may be extracted from the rotating output shaft directly, or through pulleys, gears, or other means. The turbine may be enhanced by addition of a cylinder between the base of the cone and the end cap, providing more surface area for energy exchange.
