In rural parts of the world, people are forced to be more creative with the resources available. Here are a couple examples of how this is the case:
*The flat blades can be created by cutting a PVC pipe lengthwise, using a saw or similar device, and then heating the pipe over a fire. Once hot, it can be molded into a long, flat blade.
*Washers can be made by hammering bottle caps to be flat and then punching a hole through the middle.
In these circumstances, nails, rocks, fire and wood become the tools to build the wind turbine. Steel or rocks can be used as hammers and bicycle spokes can be scraped along a rock to create a flat edge and plastic bags can be melted to build a handle around one end. Furthermore, drills can be created made out of a maize-cob as a handle and an extruding nail. The nail can then be heated over an open fire until it becomes red hot and then be used to penetrate through certain materials. <br>
