   If we plan on making a toothed wheel with inductive pickup part of
the design then the flywheel style alternator will need to go onto the
opposite end of the shaft. The magnetic field of the alternator will
interfere with the timing pickup. It looks like Renesis has the
toothed wheel behind the pulley.
   The DIY wind power generators I have seen are very close and are
called "axial flux"
   The coils are turned were they look like a bunch of 'O's making
petals to a flower.

   The places for the axial flux alternator:
      Prop flange
           prop rpm
           part of the split PSU and still in design phase
           moment is large
      between the planet cage and fly wheel
           engine rpm
           part of the split PSU and still in design phase
           moment is large - ~16"
      Pulley side
           Move toothed wheel to flywheel - minimal moment change
           Could be part of an accessory case design
           moment
