A wind turbine 20 has a turbine wheel 22 with a perimeter rim 24 and/or an intermediate rim 117 that are concentric with the axis of rotation of the turbine wheel. Electrical generators 46 and 48 are placed in engagement with the rims, with the generators formed in pairs that engage opposite surfaces of the rims. The electrical generators are mounted so that they may move laterally in response to the axial “wobble” likely to occur in the rims of the turbine wheel.
