Subject: Would a wind turbine shaped like a cup anemometer produce greater power?

I have researched that Horizontal-Axis Wind Turbines produce only about 50% of 
the power of a Vertical-Axis Wind Turbine. Both Gorlov’s helical turbine and 
the Darrieus wind turbine utilize large aerofoils. These aerofoils succumb to 
drag when perpendicular to the wind direction, decreasing power generation. 
Would a Horizontal-Axis Wind Turbine shaped like a larger version of a 
hemispherical cup anemometer theoretically provide more power? I ask this, as 
because wind is almost constantly horizontal, the force would always be placed 
against the concave cups, causing no "on-and-off" drag by a rotating aerofoil. 
Also, even if it cannot produce as much power as a single Gorlov or Darrieus 
tower, the design of the HAWT would allow a series of these cup-shaped blades 
to be placed up and down a tower, allowing more "rotating cups" (and 
therefore, power) than a single aerofoil tower, allowing power production to 
be determined by height of tower.
