These plans describe how to build two sizes of machine. The diameter of the larger wind-rotor is 8 feet [2.4 m]. The smaller machine has 4' diameter [1.2 m].

This manual describes how to build a 'permanent magnet generator' (PMG). We can also call it an 'alternator', because it generates alternating current (AC). It will not generate 'mains voltage' or 'utility power' AC. It generates low voltage, 'three phase' AC, and then changes it into 'direct current' (DC) for charging a 12 volt battery.

Here, you will find instructions for building a Savonius Rotor for water pumping. The Savonius Rotor, although not as efficient as a windmill of comparable size, lends itself to water pumping for irrigation in underdeveloped areas due to its low initial cost, simplicity of materials and construction and low maintenance cost.

The plans in this booklet are for a wind turbine that really works from someone who lives with and depends on wind energy. The brakedrum windmill is a proven design that Hugh has operated at a remote, windswept headland in northwest Scotland since 1993.

The stator is the very important electrical part of the wind turbine. It contains all the coils of wire which will have voltage induced in them as the magnets pass over them. It's defined as the 'stator' because it is the 'stationary ' (it doesn't turn ) part of the alternator. For this project you're building a 3 phase alternator and the stator will have 9 coils.

Wind can be an excellent choice for isolated power supply, and such is the nature of the folk who live in such places that many will prefer to 'DIY' wherever possible. This book does an admirable job in filling a gaping hole in the available literature on practical small scale wind engineering. It comes from a disciplined and highly trained devotee who has explored all the angles and learned most of the lessons (many of them the hard way).

This document will show you how to build PicoTurbine—a fully functioning, electricity-producing scale model of a Savonius wind turbine. It is an easy to build educational kit with Building instructions, Teacher’s guide, and Technical Notes for grade 5 through adult. For hobbyists, science fairs, schools, home schools, youth groups, and experimenters.
