However, it would be nice to have at least a little electricity, since so much of life in the twenty-first century is dependent on it. No electricity equals no light pollution. The problem is, it’s so remote that there is no electrical service available. I am an astronomer and wanted a place to practice my hobby far away from the terrible light pollution found near cities of any real size. Several years ago I bought some remote property in Arizona. You can purchase this book from the Mother Earth News store: Do It Yourself Projects to Get You Off the Grid.
Twenty Instructables illustrate just how simple it can be to make your own backyard chicken coop, or turn a wine barrel into a rainwater collector. This Instructables collection utilizes the best that the online community has to offer, turning a far-reaching group of people into a mammoth database churning out ideas to make life better, easier, and, in this case, greener, as this volume exemplifies.

Individual wind turbine blades can be cut out of the pipe using a jigsaw or hacksaw blade, or a one-piece pair of blades can be made. Obviously you need to take care to ensure that the blades cannot bend back far enough to hit the wind turbine mast. In strong winds the flexibility of the PVC blades is useful as it takes some of the energy out of the wind preventing the wind turbine generator from spinning too quickly and being damaged. Best of all, if your wind turbine generator is damaged in a storm it is very cheap and quick to put together another set of turbine blades.
Fortunately there is an alternative: PVC (or ABS) pipe cut to size. (Click here to find out more about Making Wooden Wind Turbine Blades). Typically blades are carved from wood, but this is very time consuming, difficult, and requires a wide range of tools (saws, drills, sanders, clamps, work bench etc). Wind turbine blades go through enormous stresses and must be made to quite tight tolerances if they are to balance and not send destructive vibrations through your wind turbine. One of the most difficult parts of making your own wind turbine is producing suitable blades. PVC wind turbine blades can simply be bolted onto a Permanent Magnet Alternator or suitable Stepper Motor and you already have a basic wind turbine. The raw material, PVC pipe, is easy to find, relatively cheap, easy to work with, and performance is more than acceptable for a small basic wind turbine generator. PVC Wind Turbine Blades are becoming more and more common for homemade domestic wind turbines.
