A water-flow power generating apparatus for generating electricity by a force of a water flow in water includes a main body including one rotor configured to rotate by a force received by blades from a water flow, a generator generating electricity by a rotation force of the rotor, and a pod accommodating the generator; a mooring cable for mooring the main body to a bottom of water; and a connecting mechanism for connecting the mooring cable to the pod. The mooring cable and the pod are relatively movable along a vertical plane orthogonal to a center axis of the rotor. A center of buoyancy of the apparatus main body is on a vertical upper side with respect to a center of gravity of the apparatus main body.

The present turbine is intended for use in the field of renewable energy. The turbine comprises a rotor with a guide apparatus disposed thereon, said guide apparatus having inlets for a working fluid which are in the form of ducts that spiral around each other in helices and have nozzles situated along a tangent to the circle of rotation. The guide apparatus is configured in the form of adjacent ducts which are open along their entire length or along at least a significant portion of their length and are situated on second order surfaces of revolution or on portions of such surfaces, and in particular on convex-concave surfaces of the pseudosphere type with a cone in the pole of an axial cowl of the rotor. The result is in simplification of the structure and reduction in the turbine mass, the gyroscopic effect and the starting speed of the working fluid.
