In a wind power generating system, a pair of axially spaced turbines are connected to an outer rotor and an inner rotor of a generator, respectively, and are provided with blades having equal but opposite pitch angles so that the inner and outer rotor rotate at a same rotational speed in opposite directions. The carrier receives both a power signal and a command signal from a controller via an electrically powered surface of a drapery rod. Each B block having segments of one or more polymerized vinyl aromatic monomers selected from unsubstituted styrene monomers, ortho-substituted styrene monomers, meta-substituted styrene monomers, alpha-methylstyrene, 1,1-diphenylethylene, 1,2-diphenylethylene and mixtures thereof.
