Green Options

Utility-scale windpower is an important and growing part of the US energy portfolio. Farms ranging in size from dozens to hundreds of turbines can produce in excess of 60 megawatts of power. Plans for gigawatts of wind power are being proposed all over the globe, and new wind farms are regularly being proposed that outstrip one another to be the largest in their respective locations, or in the world. At the far end of the scale, the largest size wind turbines have a rotor diameter of 126 meters (413 feet), and are estimated to be capable of producing 20,000,000 kilowatt hours of electricity annually (enough to power as many as 5000 European homes). Since the power generated by a turbine increases exponentially as it gets larger, new turbines will continue to grow in size.

But small-scale turbines are perhaps a more exciting realm of development. The standard, propeller-style turbine is well established, and there are many suppliers for this kind of generator in a range of sizes. In 2007, Home Power Magazine had a roundup of more than a dozen small wind turbines ranging from 8 feet to 56 feet in diameter (the latter of which is far larger than even a large, inefficient household would need for their power requirements). Green Building Elements had a review of this article last year.

What better way to start making art out of your supposedly useless junk than to learn from our forefathers (and mothers)? Our wasteful generation, so used to disposing of whatever we are bored with or whose intended purpose has been fully utilized, is just now learning to maximize the resources we possess. Our grandparents, of course, had been recycling long before polar bears started shopping for floaties. Of course, they turned their Oats and Barley boxes into lampshades out of necessity, not green sensibilities.

The wonderful think about folk art is its utter versatility. You can use anything you own, broken or intact. You can super glue some broken plate pieces, old car keys, a car battery, ten randomly bent paper clips, and a torn washcloth together to make a diorama of the Palestinian-Israeli conflict.

Some of you may have the unfortunate affliction that causes everything in your house to break. This problem, commonly known as “Children” can turn everything you own, expensive or priceless, into useless junk. Of course, these debris can be collected and welded together into art that can awe your friends and strike fear into your progeny!

There has been a resurgence of this sort of behavior as of late. All around the world people are taking household items and squishing them together in a global mosaic of junk art. With them leading the way we can all test the limits of our creativity, ingenuity, and the patience of our significant others. (I will warn you now, ask before you start rummaging through their junk drawers. Sometimes a screw driver or Indian penny has more sentimental and/or monetary value than you realize.)
