This website documents the design and construction of a home made wind powered generator or wind turbine.
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!
