Air fan - the base stuff for making a windturbine
Original fan motor is usable
... just make a cuts in the rotor and add neodymium magnets (from hard drive)
two times of course
A PVC waste-pipe is good material for make a twisted blades
cutting an original prop is needed to make the hub
(but much better is to make a new hub from steel or aluminium)
The other things are very easy ... Be inspired!
That´s all, folks.
