People's Wind Screw proto 1

This is my first prototype. Every strut is equal length, some string tension members.It moves with barely detectable wind with no load.Easily balanced.Actually works better with axis horizontal. Looks delicate, I like that.

Hi Frank!
Good to hear from you, kinda 'fraid you'd fallen off the face of the earth. However, I see instead that you have been busy creating away with your wonderful tallent! I like the wind screw! Kind of remains me of old sailing ships coming across the horizon. How about a little info on the construction?

Construction

Hi Rob,
The basic structure is a bunch of icosahedron middle sections, joined to make a cylinder. There is a helical pattern when you make this structure. I attached tetrahedrons to some of the faces. The protruding tetrahedrons were covered with paper to make the five helical wind catchers. I need to refine the shape to make it smoother. I believe that airfoils (wing shapes) could easily be attached instead of just drag moving the thing.I am trying to make this easily to assemble.
