Or pretty much any hub from a vehicle with disc brakes, really.

The right MacPherson strut gives you a swivel too.

The Volov people also have a pretty good website that's worth a look.

There's
also some guy making blades using cut-down bits of (4", IIRC) PVC pipe
and he claims that they're effective - I'd be interested in comments from
anyone who's tried that.

There's someone who needs to look at the difference between an impulse
and a reaction turbine.


Wind turbines are dead easy. Wind turbines on poles are much harder.
Making a practical power source is as much about getting a design that
works usefully on an affordable pole, rather than some poorly
efficient solid disk or Savonius rotor, then trying to find a pole
that can reliably support it and its varying side loads.
