A new design for large wind turbines permitting a substantial reduction in weight and cost. Lightweight airfoils comprising the turbine blades are supported within an extensive space frame system which eliminates the large bending moments to which the blades of a conventional wind turbine are subject. The turbine's useful power output is produced by lightweight electrical generators mounted inside nacelles located at the wind turbine's rotational perimeter. The nacelle-mounted generators are driven by separate, pivotable, high RPM retropellers whose high RPM is made possible by the resultant high airstream velocity encountered at the turbine perimeter.
