A Small Wind Turbine You Can Make Yourself
As the June 17 deadline to the Instructables Green Design Contest fast approaches, Jaymi Heimbuch at TreeHugger has highlighted one particular entry: a small DIY wind power generator that can sit in your backyard.
The wind generator’s designer, out-of-the-box, offers demo videos and text instructions accompanied by photos. As the designer notes, the amount of electricity the generator can produce depends on the steper motor you choose to use when constructing it yourself. The one shown in the instructions tops out at 8 volts, but on a still day outputs around 4. Modifying the turbine to increase efficiency, out-of-the-box is posting updates after the last step in the instructions, like removing a cup off of each arm to reduce wind resistance and adding unobtrusive solar panels.
This contest’s accessibility stands out among some other green design competitions. It doesn’t involve prototypes that use obscure materials or require years of experience in aerospace engineering. Instead, each entry must provide step by step instructions to show others how to make the project themselves.
