:) me too . In axial generator 1 blade win energy 2 lost. If size is huge rpm are low . Is this true ?
See film 3 and 6 in my profile this is now way axial & generator with 1 blade

VAWT is not efective .See in my profile axial and fin with huge blade that's working in 1.5 m/s in human run speed wind.

the diameter of the 2 green rotors are exactly the same 1000 mm (the one on the right is simply closer to the camera.)
diam 1000 mm= 3,1416 meter.
It means :at 4 m/sec the wind makes a distance of12,5664 meter
the darsav makes 168 rpm at 4 m/sec
that means the darsav makes a distance 35,18592 meter
that means : nearly 3x windspeed (2.80121 x)
as simply as that
But like i told you : forget about the darsav (it's impossible to get balance)
It was just a nice try....

logical

we gave up on the darsav because we have now the HYBRID (56% !!! Betz)
the highest cP ever created by a windmill (i think...)
