With all the emphasis on massive power-generating wind turbines it is important to remember that wind energy can also operate on a much smaller scale. Take this wind-powered cell phone charger for example. While perhaps not quite as portable as your typical charger it would be easy to set one of these up at home and save a little energy and money each time you charge your phone – not to mention that you won’t need to be near an outlet to use it and could also therefore take it on trips anywhere.
