A wind impeller that includes at least two rotor assemblies mounted to a base for rotation. Each rotor assembly has a plurality of spaced arms extending radially from a rotation axis with a vane attached at the end of each arm. The at least two rotor assemblies are mounted such that the rotors are rotatable through a first region in which the arms of the rotor assemblies converge and intermesh to travel along the same path and a second region in which the arms of the rotor assemblies diverge to travel along separate paths. A baffle plate is mounted to the base for directing wind against the vanes when in the second region to maximize the effective driving force of the wind.
