DIY Wind Generator
Alternative energy projects are becoming increasingly popular. Not only is it a great way to save money (which is certainly a popular thing to do these days), but you can also help our environment by reducing emissions. Regardless of your believe on man-made climate change, certainly everyone should agree about the desirability of cleaner emissions and not polluting our air.
Also, ending our reliance on (largely foreign) finite energy sources would be a great idea for our country. Every little bit helps, which is what makes do-it-yourself wind generators and other DIY alternative energy projects so intriguing.
