High Tech / Low Tech Power Generation

Volunteers from Engineers Without Borders have developed a small wind turbine that will bring power to remote villages.

The engineering team had to make their design simple enough that it could be assembled from cheap and widely available components. As a result, their plans call for building the turbine out of hard plastic (or canvas) bolted on to a steel-tube structure. The rotor, which creates mechanical energy from the movement of the blades, runs into an alternator (actually a cheap DC motor running in reverse), which converts the mechanical energy into electricity.

Wired has the full story.
