This is a rough draft of a Darrieus/Savonius combination vertical-axis wind turbine intended for use with an axial flux generator.I don't recommend you try to make this thing yet! I'm still saving up for a RepRap, so I don't know how well it works, if at all. I'll post more instructions as I progress with the project, but the basic idea is:1) assemble an axial flux generator as described on the page for that Thing 2) print 8 rotor_arms 3) print 1 rotor_airfoil_tie 4) secure 4 rotor_arms to the bottom rotor of the generator 5) secure the other 4 rotor_arms together with the rotor_airfoil_tie 6) cut a sheet of plastic into 4 airfoils of your desired size (I'm planning on 3' tall) 7) secure each airfoil between two rotor_arms with superglueYou should have a functional wind turbine!
