An apparatus employing an assembly of four flat vanes is disclosed for obtaining kinetic energy from a working fluid. The four flat vanes are disposed in two moveable pairs, that vary in frontal area in a working fluid, to produce torque about a central axis of rotation. One or more of the apparatuses are mounted on a vertical shaft unto which may be secured a pulley for distributing power in a conventional way.
