A cheaper way to make Lenz VAWT wings?

I've like the idea of a Lenz II wind turbine for quite awhile - but the wings have struck me as being a little over complicated.

So I wondered if these garage wall hooks couldnt be used to make a simpler structure. I spotted them at my local hardware store (Bunnings) for $3 each. I prefer using premade components where I can.

Maybe in some future build I will give it a try....
