ONLINE DIAGRAMS ETC TO BUILD A SMALL WIND GENERATOR @ windpower.org.za or google The Wind is Free!
The generator had to fulfill the following design criteria:
An effective source of alternative power, allowing the generation of a portion of the electricty required for the household
Constructed using only a drill press and bandsaw (although rotors needed industrial cutting), and avoiding high technology
Small and light
enough to be picked up and mounted by hand
Made from readily available materials
Items such as bearings and the shaft
should be easily available and low cost
Safe: i.e. if something failed or broke damage to property would be minimal
Cheap, but sturdy enough to withstand a Northwest gale in Cape Town!
