A fluid turbine designed for increased power output including an annular housing provided with a semispherical dome for directing incoming fluid flow from a fluid source in an angular and downward direction to impinge simultaneously on a plurality of radial, horizontal, rotor blades within the housing fixed to a vertical output shaft. The simultaneous impingement of the incoming fluid on all of the rotor blades quickly overcomes the initial inertia of the blades to rotation and maintains the rotor operating at peak velocity. The housing rotates independent of and coaxial to the rotor blades so as to position its fluid entrance passage normal to the direction of fluid flow and is provided with a plurality of fluid exit passages in its base so that deenergized fluid can be flushed from the housing by the downwardly directed flow which in conjunction with a low pressure area created behind a downwardly directed frontal scoop connected to the housing, which blocks the path of flow of the ambient fluid, causes additional fluid to be continuously drawn into the housing at high velocity to impinge on the rotor blades. The housing is gyroscopically stable and prevents the rotor from cutting back into the ambient fluid, which would retard rotation, while serving as a safety shield against flying debris entrained in the fluid stream.
