Apparently wind turbines are not all that complicated to put together, as this little experiment shows. There are many situations where you might need a small amount of electricity, for instance running gate openers, safety lights and other low-power devices. If you don't want to opt for solar panel, you might give this turbine a try. This site shows how to make a simple savonius wind turbine to power a gate opener. :: Savonius Wind Turbine via Mad Experiment
