BRAKEDRUM PERMANENT MAGNET ALTERNATOR 

In 1993 I produced plans for building a windmill based on a permanent magnet alternator from the brakedrum of a van. This is an
updated edition.  34 page detailed, step by step guide to building a 300 watt windmill with 2.1metre (7 foot) diameter. I have built one and it has
worked for years on the hill near my house, producing an average output of 100 watts (at the battery). Readers may need to adapt the method to suit
their own brakedrum.  It is a simple, robust and efficient windmill.
              ... congratulations on providing the most riveting reading I have seen for years. The technical content
                alone is worth more than most folk would imagine, and the non-technical are catered for admirably.

REVIEW BY PAUL GIPE

 "Brakedrum Windmill includes detailed instructions for building the entire wind turbine, from carving your own blades for a 7-foot (2.1 meter)

diameter rotor to building your own permanent-magnet, direct-drive
alternator capable of generating real power. By following these plans you
will construct a genuine wind turbine--not just a toy--that can reliably
churn out 300 to 400 watts. "
