Like a mighty wind pdf download

Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to like a mighty wind pdf download my hobby far away from the terrible light pollution found near cities of any real size. I found a great piece of property.

The problem is, it’s so remote that there is no electric service available. No electricity equals no light pollution. One thing I noticed right away about my property is that most of the time, the wind is blowing. Almost from the moment I bought it, I had the idea of putting up a wind turbine and making some electricity, and later adding some solar panels. This is the story of how I did it.

Not with an expensive, store-bought turbine, but with a home-built one that cost hardly anything. If you have some fabricating skills and some electronic know-how, you can build one too. More details on this project and my other alternative energy projects including my home-built solar panels, and my home-built biomass gasifier can be found on my web site. I started by Googling for information on home-built wind turbines. There are a lot of them out there in an amazing variety of designs and complexities. I reduced the project to just five little systems.

If attacked one at a time, the project didn’t seem too terribly difficult. I decided to start with the generator. My online research showed that a lot of people were building their own generators. That seemed a bit too complicated, at least for a first effort. Others were using surplus permanent magnet DC motors as generators in their projects.

This looked like a simpler way to go. So I began looking into what motors were best for the job. The best apparently are a couple of models of motor made by Ametek. The best motor made by Ametek is a 99 volt DC motor that works great as a generator.

Unfortunately, they are almost impossible to locate these days. There are a lot of other Ametek motors around though. They don’t go that cheap these days. Blades and a hub to connect them to were the next order of business. A lot of people made their own blades by carving them out of wood.

That looked like an outrageous amount of work to me. I found that other people were making blades by cutting sections out of PVC pipe and shaping them into airfoils. That looked a lot more promising to me. This web site tells you how to make a set of blades for a small wind turbine using PVC pipe.
